Abstract: PURPOSE:To simplify the circuit constitution for phase operation and phase matching of chroma signal and to achieve small sized and low cost system, by making the selection of a switch, through the use of a control siganl applied based on horizontal and vertical synchronizing signals in a TV camera. CONSTITUTION:A color difference signal is separated from a processing circuit 40 from an output of a monotube type color pickup tube 39 of a TV camera 66 and after chroma processing, it is applied to a contact-a of a selector switch 55 inverting the phase of chroma signal each 3-line and to contact-b connected to an inverter 56. A switch control signal S of a selector switch 55 is given with an output in 1/3 frequency-division for the horizontal synchronizing signal and this output is swithced with the output in 1/2 frequency-division of the vertical synchronizing signal and given to other inverters. Thus, the output of the switch 55 is a chroma signal C of (00pi) or (pipi0) every field, and applied to a selector switch 69 connected to an inverter 70 at a Y-C separation curcuit 2 of a VTR 67 and becomes the chroma signal C of (000) phase through the switching of a control signal S.

CONSTITUTION:When a current is made to flow through a coil 5, the main magnetic pole 1 and the return path part 2b of the soft magnetic substance layer 2 are excited by the part of the opposed face of a magnetic recording medium and the part 2a on the opposite side of the soft magnetic substance layer 2 is excited by the rear part of the coil 5. A magnetic flux generated by the excitation of the main magnetic pole 1 and the soft magnetic resubstance layer 2 is focused on the head part 1a of the main magnetic pole 1 and it executes effective recording in the perpendicular magnetic recording layer 13 of a magnetic recording medium 10. And the reture path 2b of the soft magnetic substance layer 2 is made to tilt against the main magnetic pole 1 and formed to have an azimuth so as to obtain an easy waveform of a sub pulse. Now, it is desirable that the width l of the tilt of the return path part 2b is made longer recorded waveform.

Abstract: PURPOSE:To allow only the normal contractor of TV reception to obtain the normal picture and sound, by giving a low band conversion to the color signal in a video signal, composing the output of said conversion with the FM modulated luminance signal to transmit the compounded signal and giving a high band conversion to the input signal received the wave detection at the receiving side to compound the input signal with the demodulated luminance signal for transmission. CONSTITUTION:A video signal Sa of NTSC system is applied to an input terminal 3, and the separated 10 luminance signal (y) of one side receives an FM modulation 11. The chrominance signal (c) of the other side receives a low frequency conversion 12. These signals (y) and (c) are then added together 13 and delivered through a terminal 5 after an AM modulation. At the receiving side, an input signal receives an AM wave detection 7 to be separated 14. The FM modulated signal (y) of one side is Fm demodulated 15 to obtain the luminance signal (y). For the chrominance signal (c) of the other side which received a low band conversion, the normal color signal is extracted via an adder circuit 17 after a frequency modulation 16.

Abstract: PURPOSE:To achieve the simplification of construction and reduction of cost by providing the rotation-control mechanisms which revolve and control various adjusting rings rotatably mounted to the lens barrel with the single driving output shaft. CONSTITUTION:The iris-adjusting ring 2, zoom-adjusting ring 3 and focus-adjusting ring 4 mounted rotatably to a lens-barrel 1 are revolved and controlled by a single driving output shaft 8 parallel to the optical axis of the lens barrel 1 and rotation control mechanisms 18, 19 and 20 for various adjusting rings. For example, to manually operate the iris-adjusting ring 2, the current supply to a solenoid 25 is stopped to release the suction action of magnets 22, 23 and detach idlers 31, 32 from the adjusting ring. Next, to expand or reduce thw exposure of iris current is supplied to the solenoid 25 that the idler 31 or 32 makes contact to the adjusting ring 2. The respective rotation-control mechanisms for zoom and focus are operated in a similar manner. In this way, the mechanisms may be simplified.

Abstract: PURPOSE:To improve the sensitivity of the head by arranging it so that a film surface can be parallel to the recording face of a magnetic recording medium in the film thickness direction of a return path code and a main magnetic pole can be almost vertical to the recording face. CONSTITUTION:A back return path core 4 and front return path cores 2 and 3, which are connected to the both end parts of the back return path core 4 and reveal one part on a sliding surface 6 of the magnetic recording medium at least, are successively laminated and formed. The central part of this back return path core 4 is protruded to the side of the sliding face 6 of the magnetic recording medium, a conductor coil 7 is spirally embedded so as to wind a protruded back return path core 4a and on the protruded back return path core 4a, a main magnetic pole 1 is provided so that it can be almost vertical to the film surface of this back return path core 4 and the top can be exposed on the sliding face 6 of the magnetic recording medium. Thus, since the head is constructed by thin film forming technique to arrange the front return path cores on the both sides of the main magnetic pole, the miniaturization of the entire head can be expected, and the sensitivity can be improved by miniaturizing a magnetic circuit.

Abstract: PURPOSE:To improve packaging density by forming two coils through a wall made of an extremely thin insulating material formed mainly by sputtering. CONSTITUTION:A 2nd insulating layer 7 is formed by thinly coating all the surface of a base substance with an insulating material such as Al2O3 and TiN. The 2nd insulating layer 7 is divided to a crown part 7a formed on a 2nd resist layer 4 and a U-shaped groove part 7b formed along the inner wall of an opening part 5, which are discontinuous. Said layer 7 is formed with technique of vacuum thin film formation, concretely, vacuum deposition or sputtering, etc., is applied. Especially, it is desirable to apply sputtering with the conditions properly selected so that the insulating material is made to adhere well even to the side wall of the opening part 5. The U-shaped groove part 7b functions as an insulating wall between two coils 8a and 8b and the thickness thereof can be made small to the extent of 1mum if it is formed by sputtering. Thus, the packaging density and the number of turns of a conductive coil can be improved.

CONSTITUTION:A non-magnetic substrate 11 such as ceramics, etc., is made to adhere with with the thick film part 12a of the main magnetic pole and after etching is made to adhere with a non-magnetic film 13. Next, a thin film part 12b is superposed on the thick film part 12a to be formed and both 12b and 12a are set as the main magnetic pole 12. An insulating layer 14 is formed all over the main magnetic pole 12 and a spiral coil conductor 15 and the insulating layer 16 covering the conductor 15 are made to adhere and formed on it. Next, after previously installing a window part 17 which reaches the main magnetic pole 12 in the insulating layers 16 and 14 and the non-magnetic layer 13, the saw-tooth tilt is formed on the insulting layer 16 [area (x) in figure] near the head of the main magnetic pole 12 after the etching resist 18 is formed in the stripes having desirable ruggedness and the sane pitch. Then on the ruggedness part 16b a soft magnetic layer 19 which becomes a return path core is formed and etched into a specified shape. Thus, a single magnetic pole type magnetic head having azimuth can be easily and precisely produced.
