IPC: H03G3/20
Filed: 1989-05-22
Abstract: PURPOSE:To obtain a microphone output signal in response to a level of a song output signal by synthesizing a sound signal amplified or attenuated with a level variable means and a reproduced sound signal and outputting the synthesized signal. CONSTITUTION:An accompanyment + song output signal 1 being a sound multiplex output and an accompanyment output signal 2 are given to a double channel subtraction circuit 3, the accompanyment output signal 2 in common to both channels is subtracted to generate the song output signal 4 and it passes through a level hold circuit 5.

Title: Electrophotographic copying machine
Inventor: SHIMIZU TOSHIO
IPC: G03G21/00
Filed: 1981-08-14
Abstract: PURPOSE:To ensure the even concentration of an image, by delaying for a certain period of time at a time point when a fault is recovered and a series of processes are performed again in case the abnormal light is irradiated to a photoreceptor and then reserving the copying operation until the potential of the photoreceptor is stabilized. CONSTITUTION:A series of copying processes including the charging 2, image exposure 3, development 4, copying 5, cleaning 7 and destaticization 8 are performed on a photoreceptor drum 1. If the cover of the copying machine main body is opened due to the occurrence of the paper jam, etc., the surface of the drum 1 receives an abnormal exposure by the disturbance light. Thus the electric charge of the electron, the positive hole etc. is caught at the trap existing inside the photoreceptor to cause the so-called fatigue phenomenon. As a result, the charged potential of the photoreceptor is lowered. After the paper jam is recovered, the copying operation is reserved for a certain period of time until the potential of the photoreceptor is stabilized in order to eliminate the effect of the abnormal light.

Title: Recording and reproducing system of sound signal
Inventor: NISHIMURA MASARU
IPC: G11B20/00
Filed: 1982-07-20
Abstract: PURPOSE:To perform reproduction with no effect of noises generated when a video head is switched, by eliminating periodically a part of the reproduced sound signals by a time axis expanding circuit and at the same time reproducing the remaining signals with extension of the time axis. CONSTITUTION:The signals reproduced by video heads 5 and 6 are amplified and then switched mutually with 60Hz by a switching circuit 12 to receive the video and sound reproductions through demodulation circuits 13 and 14 respectively. For the demodulated sound signal, the switching point part is removed by an analog switch 15. Then the demodulated sound signal undergoes a time axis expansion through a time axis expanding circuit 16 and is extracted through an output terminal 18 via an LPF17. The head switching position varies from the front edge of a vertical synchronizing signal within a 5-7H range. However, the effect of switching noises covers a considerable period, and therefore a 5-10H range is blanked by the switch 15. Then this period is approximately defined for expansion of time axis.

Title: Automatic adjuster of tape tension
Inventor: HONDA SHIGEMICHI
IPC: B65H59/16
Filed: 1977-10-24
Abstract: PURPOSE: To make the back tension of tape of always stable constant value satisfactorily by finely vibrating a tape guide with an electro-mechanical transducer thereby controlling its friction coefficient with the tape.  
     CONSTITUTION: A tape guide 2 which is provided therein with an electro-mechanical transducer formed by a piezoelectric ceramic cylinder 3, electordes 4a, 4b, etc. is finely vibrated in its circumferential direction by the high frequency electric signal being applied to the electrodes 4a, 4b. When the amplitude or frequency of this high frequency electric signal is controlled according to the signal corresponding to the back tension of the tape being detected by a tape tension detecting means 18, then the friction coefficient of the guide 2 and the tape changes, thereby changing the back tension being applied to the tape. In this case, the friction resistance is smaller as compared to that in the case of a stationary guide owing to the fine vibrations of the guide 2 and therefore the back tension being applied to the tape stabilizes at an always constant and small value, and is thus well adjusted and controlled
