Title: Wave generating device
Inventor: MUTAGUCHI KATSUO
IPC: G01M10/00
Filed: 1988-06-08
Abstract: PURPOSE:To eliminate the influence of a wave which operates on the rear surface of a wave generating plate main body by detecting a wave force by a force sensor provided to a wave generating plate, and correcting a set wave generation signal and driving the wave generating device. CONSTITUTION:A rack 2 is installed in an experimental water tank 1, the wave generating plate main body 3 is supported by a support structure 4 and installed in the rack 2, and the main body 3 is constituted having a hollow by a front wave generating plate 13 and a rear wave generating plate 14. Then the force sensor 15 provided on the reverse surface of the wave generating plate 13 detects the wave force F and sends it to a wave generation correcting computing element 16, which compares the wave generation signal set by a wave generation signal generator 17 with the wave force F to perform correcting arithmetic operation; and the result is sent to a motor driving unit 18 through a position control computing element 21 and a motor 7 drives the structure 4 and main body 3 reciprocally. Consequently, the forward and backward moving forces of the motor 7 are controlled with a force which is detected by the sensor 15 and applied to the main body 3, so while a reflected wave from the wall surface of the opposite wave generation side is absorbed, a specific period and specific wave height are obtained.

Title: Method for sampling video signal
Inventor: TAKAHASHI MORIYOSHI
IPC: H04N9/64
Filed: 1991-06-13
Abstract: PURPOSE:To prevent color display from being defective by making close timing for changing a sampling pulse from high to low for the same display unit generated in a video signal driving circuit. CONSTITUTION:The cycle of sampling clocks phi1 and phi2 is regularly changed with ts1-ts3 as one cycle and for the cycle ts1-ts3, the dot cycle of the video signal has the fixed relation with tvo as well. Between the sampling clocks phi1 and phi2, there is phase difference corresponding to the dot cycle tvo of the video signal. Start pulses ST1 and ST2 are set corresponding to the start edges of the correspondent sampling clocks phi1 and phi2. Therefore, the timing to change the sampling pulse from high to low (to close a sampling gate) is made close at sampling pulses Q11, Q21 and Q12 corresponding to picture elements R1, G1 and B1.
