    Abstract: PURPOSE:To make television broadcasting receiving antennas on a movable body possible to receive a television broadcasting signal having extremely less ghost by laying at least four dipole antennas on the roof of a movable body with their mounting directions set different by about 90 deg. from one another in nearly the same horizontal plane. CONSTITUTION:Four antennas 30a, 30b, 30c, and 30d are mounted to the roof 2 of a vehicle body 1 in the peripheries of ventilators 3 and 4. In this case, antennas 30a, 30b, 30c, and 30d are individually formed with a dipole antenna consisting of two conductive bars with one end sections thereof are proximated and reflectors laid taking a predetermined interval distant from these conductive bars, and the gap section between two conductive bars is connected to a coaxial cable via a baloon (matching transformer) and further connected to a switch installed in an underfloor unit. Furthermore, four antennas 30a, 30b, 30c, and 30d are placed shifting their mounting angles by 90 deg. horizontally, and antennas 30a and 30b are mounted before and after the ventilator 3, while antennas 30c and 30d are mounted to right and left of ventilator 4 adjacent to ventilator 3.

    Abstract: PURPOSE:To prevent a fully black level pattern or a white noise pattern from being displayed by outputting a still picture signal just before defect of reception stored in a memory means onto a monitor on the occurrence of defect of reception. CONSTITUTION:While the reception state is excellent, a video signal and an audio signal demodulated by a tuner means 3 are outputted to a monitor 4 as they are so as to allow the broadcast is viewed, and the video signal is simultaneously fed to a memory means 3b, rewritten sequentially and stored in the unit of patterns. When the defect of reception is reduced, a changeover means is switched and a picture signal stored in the memory means 3b is read out continuously as a still picture and outputted onto the monitor 4, and preferably an audio output is muted. Thus, a still picture signal just before defect of reception is displayed onto the screen of the monitor, a fully black level pattern or a white noise pattern is not generated and the disturbance of received pattern is avoided.

    Abstract: PURPOSE:To make the electric field strength in a cabin uniform by stretching an antenna in the lengthwise direction around a ceiling in the cabin and connecting its one terminal to ground via an impedance element. CONSTITUTION:A linear conductor 1 is arranged along a slot 4b of a ceiling. A spacer member 11 is properly fitted at a prescribed interval. One terminal 1a of the conductor 1 connects to a conductor of a car body 2 via an impedance element (resistive element) 9. A grounding plate 10 is used for grounding. The impedance element 9 is inserted to a hole 16 of a metallic terminal board 12 of the grounding plate 10 and soldered. The terminal board 12 is fitted to the car body by a screw 20 for the ground connection. Through the constitution above, the on-vehicle antenna is realized, which provide the radiation of an electromagnetic wave whose electric field strength is uniform to allow excellent reception in the cabin.

    Abstract: PURPOSE:To make it possible to receive teletext at a mobile body such as electric car by using a plurality of antennas constituting a diversity antenna to receive teletext by switching each antenna at an interval of at least 1sec+ or -0.5 sec. CONSTITUTION:Four antennas 30a-30d are installed on the roof of body of an electric car with their horizontal directions made different by 90 deg. from one another, and they receive radio wave coming nearly in all directions of 360 deg., and via switching section 41 in an underfloor unit 40 hanged under the floor of car body 1, booster 42, and ghost reduction tuner 43a, a previously set channel television broadcasting signal is obtained. The television broadcasting signal thus obtained is supplied to a discriminating circuit 44, and the discriminating circuit 44 discriminates a synchronous signal level contained in the broadcasting signal, controls the switching section 41 for selection of antenna line so as to be able to obtain a synchronous signal with the best level to constitute so called a diversity antenna. In this case, this discriminating circuit 44 carries out level discrimination at an interval of one second under the control of timer circuit 45.

    Abstract: PURPOSE:To make it possible to display all the screens of always relevant teletext program by storing teletext data of screen obtained by demodulating at least one screen of teletext data of a necessary teletext program in a corresponding area in a memory and by updating data stored in the memory. CONSTITUTION:Four antennas 30a-30d are installed on the roof of body of an electric car, and they receive radio wave coming nearly in all directions of 360 deg.. Switching section 41 in an underfloor unit 40 hanged under the floor of car body 1 controls a discriminating circuit 44, and selectively outputs a received signal supplied from one from four antennas on the roof, and via a booster 42, ghost reduction tuner 43, and character teletext decoder 46 obtains the teletext signal of drawing or the like. In this case, when obtaining at least one screen of data of a previously set predetermined teletext program, this data is stored in a corresponding area of memory 47, and data of a stored predetermined teletext program is sequentially read to the teletext decoder 46, output from the underfloor unit 40, and displayed on television receivers 101-124 installed in the car.

    Abstract: PURPOSE:To prevent a tape shape body from being damaged by performing the chamfering of an edge part so that the edge part corresponding to the rotating direction of a rotary drum on a sliding contact plane with the tape shape body of a video head is prevented from being protruded over the outer peripheral plane of the rotary drum. CONSTITUTION:The chamfering of the edge part P on the sliding contact plane 11a separated by an interval f3 in a direction corresponding to the direction of rotation thetaof the rotary drum from a gap forming plane 11d is performed on the video head 11 with an angle beta along a straight line 11b. When the video head 11 is mounted on the rotary drum 1 via a mounting base, the quantity h3 of protrusion of the head 11 over the outer peripheral plane 1a of the rotary drum 1 is set at around 27mum. Therefore, spacing loss between a magnetic tape being brought into contact slidably with the slidable contact plane 11a of the head 11 can be suppressed at minimum. In such a case, the edge part S in the head 11 of the magnetic tape with the slidable contact plane 11a corresponding to the direction theta is positioned at a side inner than the outer peripheral plane 1a of the rotary drum 1, therefore, the head output of the head 11 can be improved remarkably, and the spacing loss can be maintained at minimum, and the edge part of the tape can be prevented from being rolled in the edge part S of the head 11.

    Abstract: PURPOSE:To prevent damage of tape magnetic face by quickening the peripheral speed of a tape guide part more than the running speed of a tape so as to form an air film between the peripheral face of the tape guide and the tape. CONSTITUTION:In delivering a torque to a pulley 21 from a drive source (not shown) via a belt 22, a tape guide 8 is driven and an air film 23 is formed between the tape guide 8 and the tape 18 and the tape 18 is not in contact with the peripheral face 19 of the tape guide 8. In running the tape 18 in this state, the running direction is changed by the tape 18 without being in contact with the peripheral face 19 of the tape guide 8. Plural slots 20 are formed to the face 19 of the section 8, then the contact area between the tape 18 and the tape guide 8 is decreased when the tape 18 is not driven and the initial adhesion of the tape 18 is prevented.

    Abstract: PURPOSE:To receive a teletext in an excellent state even when the directivity of an antenna is changed by selecting an optimum correct character data among the same character data obtained through plural channels. CONSTITUTION:Each of plural tuners 2a-2d has a ghost cancel function and extracts only the television signal of a specific and the same channel including a character multiplex signal among television signals received by antennas 1a-1d respectively. Moreover, decoders 3a-3d separate a character signal from the television signal supplied from the tuners 2a-2d and reproduce the character data by decoding the character signal. The decoders 3a-3d detect and correct an error by using an error correction signal. Then a correct packet data with no error correction disable flag set thereto is obtained in channels 8a-8d from an extract section 4 and the correct data packet is outputted for each horizontal scanning period.
