Title: Relief valve for brake circuit
Inventor: SAKAMOTO HIROKATSU
IPC: F16K17/00
Filed: 1980-08-29
Abstract: PURPOSE: To remove shock at starting or brake-starting of an inertia-body-revolving hydrodynamic drive device by constructing a relief valve to keep its set pressure at a low level at the initial stage of operation and raise to pressure to a high level gradually and slowly after starting.  
     CONSTITUTION: When a direction control valve 1 is switched over from a position B to a neutral position, a counter balance valve 5 is retuend to the neutral position by springs on its both ends. Meanwhile, an oil pressure motor 8 gives pumping by inertia force, and by the discharge liquid thereof, the primary side liquid pressure of a pipe line 7 is threatened to rise at a stretch. However, in a relief valve 11, a poppet 14 is lifted to keep the liquid pressure in the pipe line 7 at a low level. Then, the poppet 14 is brought in contact with a piston 25, and shifted to close the valve by the primary side liquid pressure given from its front and rear for obtaining high-pressure setting. At this stage, the shift speed of the poppet is controlled by a flow regulation valve 23 with temperature/pressure compensation, and the primary side liquid pressure is gradually risen. Consequently, an inertia body can be braked smoothly.

IPC: G05D1/02
Filed: 1977-10-07
Abstract: PURPOSE: To stably shift an unattended vehicle to a guide track in programmed turing of the vehicle, by switching the vehicle to guided movement when reverse- motion turning approaches the end.  
     CONSTITUTION: A signal proportional to the run distance of the vehicle is detected by a distance detector 11. A counter 12 counts the number of pulses of the signal. Depending on the counted value, a trapezoidal wave generator 13 generates an outpt signal Sb to instruct a steer angle. The output signal is applied to a terminal 10a of a switch 10. Depending on the guided movement or the programmed turning, the switch 10 selects one of a steering instruction signal Sa being conducted to the terminal 10a and a steering instruction signal Sb being conducted to a terminal 10b. The signal selected by the switch is applied to an addition point 14. A steer angle detector 18 detects the quantity of steering 17 by a steering unit 17 in the real steering direction and feedbacks the quantity to the addition point 14. A deviation signal is applied from the addition point to an actuator 16 connected to the steering unit 17 to perform the programmed turning

Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To improve the detection accuracy of a straight line by performing the Hough transform in a state where the image of a small value area is enlarged on the X-Y coordinates and a candidate point is shifted to an area of high X-Y value. SOLUTION: An image division means 31 sets the orthogonal coordinates (X-Y coordinates) which define the four corners of an image as an apex for an image fetched into an image memory 13A and takes out an image of small X-Y value including an original point to divide the image. An enlargement image memory 32 enlarges and stores the divided and taken out image data. An edge detection means 13C generates an edge detection image in both memories 32 and 13A respectively. Then a binarization means 13D binarizes the images of both memories 32 and 13A. Furthermore, a Hough transform means 13E applies the Hough transform to every candidate point included in the memory 32 to obtain a curve group. Meanwhile, the Hough transform is also applied to the candidate points remaining in the memory 13A. These curve groups are stored in a curve group memory 13B.

Title: Jitter measuring system
Inventor: KYO MASAAKI
IPC: H04N5/95
Filed: 1992-05-13
Abstract: PURPOSE:To measure the residual jitter in a video signal after it passes through a time base correction TBC circuit. CONSTITUTION:In test video signal generation parts 51-54, a pulse whose polarity is inverted from a horizontal synchronizing signal and whose width and height are equal to those of the horizontal synchronizing signal is set to be video information with respect to a pedestal level, and a signal obtained by adding the information to a synchronizing signal is frequency-modulated based on an external signal. Thus, a test video signal including the jitter is generated in a period except for a vertical blanking period. Then, the test video signal is led to the time base correction means TBC circuit 20, a time base is corrected by replacing the synchronizing signal and it is led to signal inversion parts 41-43. The signal inversion parts 41-43 invert the test video signal which is time base-corrected in the period except for the vertical blanking period. Since the residual jitter is present in the horizontal synchronizing part of the test video signal which is inversion-processed at the time of replacing the synchronizing signal, the test video signal is led to jitter measurement means 11-16 which can measure the jitter of the horizontal synchronizing signal and the jitter is measured.

Abstract: PURPOSE:To make a voltage difference between a boosting voltage boosted by the boosting power supply voltage and a voltage of a DC power supply circuit constant. CONSTITUTION:A voltage difference between a boosting voltage boosted by the boosting power supply circuit 14 and a voltage of a DC power supply E is detected by using an operational amplifier 17 and resistors R1-R4 as components for a voltage detection circuit and a boosting control circuit 16 controls the boosting power supply circuit 14 so that the voltage difference is constant. As a result, even when a voltage of the DC, power supply E is fluctuated, a switching element 12 is surely driven. Moreover, even when a voltage of the DC power supply E is fluctuated to a high value, since the drive current of the switching element 12 is not increased, the power loss of the resistor 13 deciding the drive current is suppressed.
