    摘要： A sheet member adapted for attachment to an acoustic or imaging apparatus to improve the acoustic or imaging performance thereof. The sheet member is generally circular, including a plurality of generally W-shaped cut-outs and a like plurality of generally V-shaped cut-outs both formed alternately and equi-angularly in the outer circumference thereof. The sheet member improves the acoustic or imaging performance by reducing the interference caused by electromagnetic radiations emitted from the acoustic or imaging apparatus or their components to which the sheet member is attached. The reduction of such interference can be attained also by forming a compact disc, a laser disc, a magnetic tape, a semiconductor chip, a circuit board, a magnetic or IC card or the like in a manner to have such cut-outs in their outer circumference.

    摘要： A charging/discharging circuit is formed of transistors Q1, Q2; resistors R1-R4; and a capacitor C. The series resistors R1, R2 are connected between the power supply line +Vcc and the circuit ground. The series resistors R3, R4 are connected between the line +Vcc and the circuit ground. The collector of NPN transistor Q1 is connected to +Vcc, the base thereof is connected to the junction between R3 and R4, and the emitter thereof is coupled to the junction between R1 and R2. The collector of PNP transistor Q1 is connected to the circuit ground, the base thereof is connected to the junction between R3 and R4, and the emitter thereof is coupled to the junction between R1 and R2. Capacitor C is connected in parallel to R2. The charged voltage of C is used as a reference potential VR for another linear circuit. Suppose that R1=R2, R3=R4 and +Vcc=10 V. When +Vcc rises from 0 V to 10 V but VR does not reach to 5 V, Q1 is forwardly biased so that C is quickly charged by the emitter current of Q1. When +Vcc falls from 10 V to 0 V but VR does not reach 0 V, Q2 is forwardly biased so that C is quickly discharged by the emitter current of Q2. When VR=5 V (stationary state), Q1 and Q2 are both cut-off, so that only small currents flow through the series circuits of R1, R2 and R3, R4. The time constant of (R1.vertline..vertline.R2).C can be made large so that VR is free from ripples of +Vcc.

    摘要： In tracing a tape with a signal recording head to form tracks having digital data recorded thereon, a plurality of tracks provide each of blocks, and a usual playback data area NA and trick playback areas TH and TL are arranged on each of the tracks included in each block. The trick playback areas are enlarged to provide increment areas TA with a decrease in the bit rate of usual playback data. In recording image data as to a plurality of programs on a tape conjointly, signal recording tracks are formed on the tape, and a usual playback data area and a trick playback data area are formed on each of the tracks or on one track per plurality of tracks, as arranged longitudinally of the track, whereby the image data as to programs A to D is conjointly recorded on the same tape. In this method, a number of tracks in accordance with the number of speed multiplication for trick playback provide one TP frame, the same trick playback data is repeatedly recorded from track to track in the trick playback data areas of the tracks within the same TP frame, and the image data as to the programs A to D is cyclically recorded in such respective TP frames, each for one program.

    摘要： In processing a video signal reproduced from a track of a magnetic disc (10), if the reproduction video signal, from one track of the frame recorded on two adjacent tracks, is stored in a memory (34), then the control circuit (20) determines whether the memory (34) should be used as a field memory or a frame memory based on a field/frame discriminating signal reproduced from the reproduced track. Therefore, error which occurs when only one of the two tracks is erased, can be prevented.
