Title: Pressure gauge
Inventor: FURAAJIYU PORIAKU
IPC: G01B11/00
Filed: 1981-05-11
Abstract: PURPOSE:To improve responding characteristics by constraining the motion of a pressure receiving diaphragm, by measuring the displacement of the diaphragm by pressure by converting it into variation in interferennce fringes. CONSTITUTION:A laser emitted from a light source 6 is separated through a half-mirror 9 into transmitted light and reflected light; the transmitted light is reflected by striking the mirror surface 2a of a pressure receiving diaphragm 2, and the other reflected light is reflected by striking a reference mirror 11. Then, both lights are guided to an interference fringe detection surface 3, forming concentric interference fringes. When the diaphragm 2 is displaced by pressure, said interference fringes move, which is detected by photoelectric detectors 14 and 15; and the number of interference fringes passing through the photoelectric detectros 14 and 15 is counted by a counter 16 to measure the displacement of the pressure receiving diaphragm 2 as a digital value which is a multiple of the wavelength of the light source.

IPC: G11B5/53
Filed: 1989-03-23
Abstract: PURPOSE:To independently perform recording without changing mechanical specification by providing a sound signal in a gap between a recording track for a video signal and a recording track for a video signal. CONSTITUTION:Supposing that the advanced mounting angle of recording and reproducing heads for sound 1 and 2 against recording and reproducing heads for video 3 and 4 is X deg., the difference of mounting height is Y, a track pitch on a tape pattern which is obtained by a low tape speed is P1 and the track pitch which is obtained by another tape speed is P2, the head is arranged on a head drum 5 with the values of X deg. and Y satisfying formulas I and II. In the tape pattern obtained by the low speed, the track for the video signal is overwritten in the center of the recording track for the video signal. In the tape pattern obtained by the high speed, the track for the sound signal is recorded in the center of the gap between the recording tracks for the video signal. Then, the width of the head for video signal is taken as P1 and the width of the head for the sound signal is taken as P2-P1. Thus, the sound signal and the video signal are independently recorded and reproduced while keeping the interchangeability with a VTR.

Title: Discriminating circuit of sweep stop signal
Inventor: SUYAMA MINEO
IPC: H03J7/28
Filed: 1982-04-27
Abstract: PURPOSE:To stop surely a sweep, by stopping the sweep when a sweep stopping signal is detected once and completing the sweep if the sweep stop signal comes again after a prescribed time. CONSTITUTION:When a pulse signal 202 outputted from a counter 12 comes during the period of the sweep stopping signal 203, an AND circuit 41 outputs a signal 204 having a pulse in the same timing as that of the pulse from the counter 12. A one-shot multivibrator 42 outputs a pulse 205 of a time constant T1. This pulse is inverted by an inverter 43, a one-shot multivibrator 44 inputs this inverting signal, detects the fall of the pulse signal 205 and then rises, and outputs a pulse signal 206 having a time constant T2. The presence and absence of the sweep stopping signal 203 is discriminated again in the time T2.

Title: Output signal lock circuit of common bus connection circuit
Inventor: TAKAHASHI YOSHIAKI
IPC: G06F13/00
Filed: 1978-06-14
Abstract: PURPOSE: To make it possible to disconnect a circuit in an operator's simple operation by constituting the circuit so that the circuit can be operated stably even if the  logical power source voltage drops and making a lock switch single.  
     CONSTITUTION: Output signals can be locked without disturbing I/0 bus signals at not only a switching time but also an insertion time of I/0 circuit 2. In case that lock switch SW15 is turned on and signal 3 is inserted to circuit 2, logical power source voltage VCC rises gradually. Then, though Tr 23 is turned on when VCC becomes equal to voltage VBE between the base and the emitter of transistor Tr23, Tr21 is not turned on until VCC reaches a voltage obtained by adding the forward drop voltage of diode 18 to voltage VBE. Consequently, until SW15 is turned off at an insertion time, Tr23 is held in a turning-on state stably, and output signals are locked. Thus, the number of required lock switches is only one, and the operation miss of the operator is reduced.

Title: Latent image forming method
Inventor: TSUCHIYA HIROAKI
IPC: G03G15/043
Filed: 1981-05-12
Abstract: PURPOSE:To obtain stable picture quality by eliminating an image density difference of halftones during variable magnification to equal magnification, etc., by holding the time when a photoreceptor moves from a pre-exposure position to a secondary simultaneous charging and exposure position constant without reference to its moving speed. CONSTITUTION:A lamp 8 is arranged behind a primary charger 4 and during variable magnification (contraction in this case), the lamp is turned on. Then, a pre-exposure position A is extended to a position A' and the distance from the pre-exposure position to a secondary simultaneous charging and exposure position B is shortened, so that the moving time of a photoreceptor 1 during nonmagnification is nearly equal to that during magnification variation. Therefore, the VM and VN of an E-V characteristic curve become nearly equal to each other and an image density difference of halftones is eliminated, thereby obtaining stable picture quality.
