Title: Moving picture decision device
Inventor: HIDARI HIROBUMI
IPC: H04N5/262
Filed: 1987-06-25
Abstract: PURPOSE: To accurately discriminate between a moving picture and a still picture at low cost with simple circuit constitution by sampling a video signal at plural points or an optional position on a picture and discriminating between the moving picture and still picture according to the difference signal.  
     CONSTITUTION: Sample-held signals from 1st and 2nd sample holding circuits 2 and 3 are supplied to a differential amplifier 4 to generate their difference signal (c). The difference signal (c) is inputted to a decision circuit 5, which discriminates between the moving picture and still picture. Namely, when the level of the difference signal is smaller than a threshold level set by the decision circuit 5, the still picture is decided, but when the level exceeds the threshold value, the moving picture is decided. Consequently, neither a large-scale memory nor a fast A/D converter is required, so the circuit constitution is simplified and the cost can be reduced.

Title: Magnetic recording and reproducing device
Inventor: IMAI TAKAHIRO
IPC: H04N5/225
Filed: 1992-05-25
Abstract: PURPOSE:To prevent a state where the rotation of a motor is stabilized from being changed even when power source voltage is varied. CONSTITUTION:A capstan motor 8 is driven by using a PWM(pulse width modulation) signal outputted from a system control servo microcomputer 5. Whether servo control output calculated in order to move the motor 8 at fixed speed is positive or negative is judged by comparing the servo control output with a specified value, and then duty at the time when the PWM signal is set to zero is varied by judging that the output is equal to or above the specified value and which is more distributed, the positive output or the negative output. The PWM duty just before changing a mode is stored in a storage part 13, and it is read out when the same mode is set again, then operation is maintained from a state at the time of storing it. Thus, the speed is made higher when the controlled result in the microcomputer 5 is positive and it is made lower when the result is negative by controlling so that zero may be set as center.

Title: Rotary electric machine with liquid-cooled circulation monitor
Inventor: INGOEDOGAARU KURAUZE
IPC: H02K9/24
Filed: 1985-07-18
Abstract: A hydraulic circuit branch of a cooling system in thermal contact with the stator winding of a hydraulic power generator is provided with a feed tube divided into two separate input tube sections. The downstream ends of the input tube sections are connected to respective multiplicities of subsidiary hydraulic circuit branches in the form of winding bars via a pair of semicircular manifolds. The current throughput through the winding bars is monitored by determining the difference between the rates of coolant flow through the approximately identical input tube sections. If the rates of coolant flow or throughputs in the input tube sections differ from one another by an amount which itself differs from a predetermined reference value by more than a preselected threshold, a warning signal is generated indicating that heat removal from the hydraulic power generator is being impaired.

Title: Antiskid controlling method
Inventor: ASAMI KEN
IPC: B60T8/58
Filed: 1983-08-30
Abstract: PURPOSE:To prevent the excessively weak brake force to be generated by measusing a time for controlling to weaken the brake froce, and extensing the control of strengthening the brake force for the prescribed time while the wheel speed becomes lower than the reference wheel speed when the time becomes longer than the prescribed time. CONSTITUTION:A braking is executed from a time t0, and when the wheel speed Vw is decelerated from the reference wheel speed Vsn, a normal antiskid control is performed. Then, the time T1 from the time point t1 than the wheel speed Vw decreases lower than the reference wheel speed Vsn to when the acceleration/deceleration V'w of a vehicle exceeds the first threshold value G1is measured. When this time T1 is longer than the prescribed time T2, it inhibits to switch an increase/decrease control solenoid D from OFF to ON during the prescribed time Tc from the time t10 when the wheel speed Vw becomes higher than the reference wheel speed Vsn from the lower state to extend the increased pressure control time of a brake hydraulic pressure C. Thus, the brake hydraulic pressure becomes higher than the normal antiskid control time indicated by a broken line, thereby preventing the hydraulic pressure from excessively decreasing.

IPC: H04M3/00
Filed: 1983-08-31
Abstract: PURPOSE:To detect dial pulses with a short delay time by applying a large pseudo inductance for an inter-line voltage change of a small amplitude and a small pseudo inductance for the change of a large amplitude. CONSTITUTION:An operational amplifier OP1 outputs a voltage VTR/2 of the half of a voltage VTR between lines of Tip and ring on a basis of a voltage VBB/2. And operational amplifier OP2 inverts the voltage of the amplifier OP1 to output a voltage -VTR/2. A capacitor C1, resistances R7 and R15, and Zener diodes Z1 and Z2 constitute a low-pass filter; and in case of a signal having a small amplitude, Zener diodes Z1 and Z2 are not made conductive but only the resistance R7 and the capacitor C1 are operated. Therefore, a high-impedance feeding circuit is realized in AC for a signal having a relatively small amplitude such as an audio signal, and this circuit responds quicly to a signal having a relatively large amplitude such as dial pulses.

Title: Scroll compressor
Inventor: SUEFUJI KAZUTAKA
IPC: F04C18/02
Filed: 1985-07-22
Abstract: PURPOSE:To safely release the excessive pressure when the excessive compres sion state is generated in an inside operation chamber by installing a unidirec tional sealing means for permitting the flow directed from an outside operation chamber to an inside operation chamber, at the top edge part in the axial direction of a scroll lap. CONSTITUTION:At the top edges in the axial direction of the lap 4b of a fixed scroll 4 and the lap 5b of a turning scroll 5, a sealing member 21 wound into the same shape to the lap is arranged. The sealing member 21 has a groove 21a on the side facing to an inside sealing chamber 30, and acts to permit only the flow directed from an outside sealed chamber 9a to an inside sealed chamber 9a. Therefore, even if the excessive compression state is generated in an outside sealed chamvber 91, the excessive pressure is certainly released into an inside sealed chamber 30 through the groove 24 formed on the sealing member 21, shoulder part of the sealing member 21, and the groove 21a of the sealing member 21.

Filed: 1979-12-12
Abstract: PURPOSE:To improve the efficiency of pump electric power by connecting voltage varactor diodes to pump electrodes on a propagation path for a surface elastic wave and by applying a pump voltage to them. CONSTITUTION:A pump voltage of a frequency twice selected frequency f0 is applied from high-frequency power source 9 to voltage varactor diodes C1-Cn. An electric signal applied to transducer 5 propagates on the surface of piezoelectric substance substrate A and while it is propagating through pump electrode groups M1-Mn, a signal component of approximate frequency f0is parametric-amplified. The amplified signal is reconverted by transducer 6 into an electric signal, which is outputted. Since the sum of widths and intervals of pump electrodes M1-Mn is made less of length lambda0 of irradiation, mechanical reflection is reduced.

Title: Coxial cable for controlling leakage quantity
Inventor: TAYA KEIICHIRO
IPC: H01B11/18
Filed: 1986-07-07
Abstract: PURPOSE:To control the leakage electric field at a low cost by employing the braiding whose braiding rate is increased/decreased in the lengthwise direction so as to constitute the titled cable. CONSTITUTION:In figure, in compliance with requirements for the applications in a tunnel requiring a uniform electric field level, S is a transmitter/receiver, 1 is a center conductor, 2 is a dielectric such as polyethylene, 3 is a metal braid and ZR is a matching resistor. The braid is densest at a feeding point F, but it is coarser gradually toward the lengthwise direction and coarsest at the position of termination E. Then the leakage quantity is least near the feeding point F and increased little by little toward the lengthwise direction, resulting that the electric field level is constant for the points of F,M,E.
