    Abstract: PURPOSE:To prevent exactly the resonance of an elasticity working part by a structure which can be worked easily, by providing as one body a rib on at least the elasticity working part of a head supporting spring by means of press working. CONSTITUTION:A rib 31 whose section is roughly a semicircular arc shape is provided as one body by means of drawing press working on the whole periphery of an elasticity working part 24 being an inner frame of a rectangular shape of a head supporting spring 21. 31 is worked simultaneously when stamping the head supporting spring 21 from a plate spring of a metal. In this way, the rigidity of the elasticity working part 24 is raised remarkably by the rib 31, and as a result, the resonance of the elasticity working part 24, generated by a rotation of a floppy disk at the time of reproduction can be prevented exactly.

    Abstract: PURPOSE:To achieve the conversion of major bit information into minor bit information with a simple constitution, by sectioning the information consisting of a prescribed bit number into a plurality of less number of bit information and inserting a switching signal at each section. CONSTITUTION:The information is outputted from a computer 1 with a binary signal in a prescribed bit number. This information is sectioned into characters and symbols at an ROM2 and converted into a binary signal in corresponding less number of bits and a switching signal if the information is characters or symbols is formed. The signals are respectively applied to a changeover switch 3. Further, the switching signal from the ROM2 is applied to a detection circuit 4 and a switching detection signal is applied to the switch 3, allowing to change over the switch for a prescribed time. The signal from the switch 3 is applied to a tape punch 5. Thus, if the switching signal is changed, the switch 3 is changed over and the switching signal is inserted at the first half of the signal.

    Abstract: PURPOSE:To improve the application efficiency of a tape, by recording address information and a tracking detecting signal in tracks along the upper and lower ends on the tape where data is recorded on a track extending in the transverse direction. CONSTITUTION:On tape recording medium 10 where data is recorded in the first track 19 extending in the transverse direction, prescribed signals which are address information as well as tracking detecting information for the first track 19 are recorded in the second tracks 17 and 16 in the longitudinal direction along one or both of the upper and lower ends. For example, servo track 17 and address track 16 are provided along the upper and lower ends of magnetic tape 10 which is in the stationary state scanned obliquely by the rotary head. Then, the tracking state is detected by change of the amplitude of the reproduced output at the scanning time of tracks 17 and 16 (the reproduced output becomes as shown in figures D and E when the scanning locus moves as shown in broken line 18').

    Abstract: PURPOSE:To read braille points at fixed locations while protecting the tip of fingers of users, by projecting the right row side of dot portion materials corresponding to one unit as delaying the right row side more than the left row side in time while mounting a buffer means to a projection device. CONSTITUTION:A pivotal motion arm 14 for pushing up and projection driving a dot portion material 10 for braille points pivotally acts slowly by means of a damper portion material 18, and gently thrust up the dot portion material 10. Dot portion materials 10A, 10B, 10C at the left row side are first brought to fixed projecting conditions in response to dot signals among dot portion materials 10A-10F for braille points corresponding to one unit, the dot portion materials 10D, 10E, 10F at the right row side are changed into fixed projecting conditions for a limited time after retardation time and braille points characters corresponding to one character are indicated by using drive means 20A-20F functioning as mentioned above.

    Abstract: PROBLEM TO BE SOLVED: To provide an optical disk having an electronic circuit and excellent in an appearance in which problems such as the disruption of a mechanical strength balance and mechanical strength reduction are solved. SOLUTION: The electronic circuit including a plurality of electronic parts is provided in a blank part 13 except a portion corresponding to a main information recording region in an optical disk substrate having a center hole 11. A plurality of non-mounting regions 31 to 39 where electronic parts are not mounted are set in the blank part in the radial direction of the optical disk substrate in advance. The plurality of electronic parts are mounted on the regions other than the non-mounting regions of the blank part 13 except for wiring to connect the electronic parts with each other.

    Abstract: PURPOSE:To provide a slip ring device in which a slip ring and a rotational position detector are formed integrally in an extremely compact shape so as to be mountable and demountable freely. CONSTITUTION:A slip ring part 15 is constituted of a rotating shaft 11 pivotally fixed in the first and the second casings so as to be rotatable freely. The slip ring part 15 and a rotational position detector 18 are formed integrally of the first casing 13 of this slip ring part 15 and the third casing having the rotational position detector 18 capable of engaging with it so as to be mountable and demountable freely.

    Abstract: PURPOSE:To enable a lighting position to properly follow an illuminated body by automatically changing the position in response to the motion of the illuminated body. CONSTITUTION:The lighting system in the title is equipped with a lighting device 1 movable in lighting position, drive means 2 and 4 to cause the fluctuation of the lighting position for light, a light receiving device 5 capable of changing a light receiving direction integrally with a lighting position fluctuation, and a transmitter 7 to transmit a specified light signal including the predetermined code signal. The drive means 2 and 4 generate a lighting position control signal on the basis of an optical signal received from the transmitter 7, and drive the lighting device 1 in order for the lighting position to follow the position of the transmitter 7. Also, the follow-up motion of the lighting position on the basis of the lighting position control signal continues, until at least the position falls within the prescribed error range. According to this construction, the lighting position can be changed to a desired position accurately, quickly and automatically.
