IPC: H04N7/00
Filed: 1990-03-30
Abstract: PURPOSE:To generate a stable variable sampling clock by frequency-dividing a master clock generated at a PLL synthesizer at a variable programmable frequency divider. CONSTITUTION:A PLL circuit is formed in a variable master clock oscillating section 1 so that a master clock is controlled at an integral number of multiple of an external comparison reference frequency and the master clock frequency is controlled by a multiple of a master clock frequency division ratio (NM) of the comparison reference frequency. A programmable frequency divider 2 is reset by an externally inputted horizontal synchronizing signal, the master clock is frequency-divided by a set sampling clock frequency division ratio (NS) to generate the sampling clock. Thus, the phase is matched with the phase of the horizontal synchronizing signal by an error of one clock of the master clock frequency to generate a sampling clock whose frequency is a multiple of NM/NS of the comparison reference frequency.

Title: Power-on clearing circuit
Inventor: KANEKO NOBORU
IPC: G06F1/24
Filed: 1983-05-18
Abstract: PURPOSE:To obtain a power-on clearing circuit which is free from a malfunction due to the power supply noise by obtaining an AND between the output signal of an oscillating circuit which detects the output of an oscillator and the output signal of a power supply application detecting circuit. CONSTITUTION:When a switch SW is turned on to apply a power supply, a differentiating circuit works to deliver a detection signal (c) to an FF14 from a power supply application detecting circuit 3. Then an H level signal (g) is delivered from the FF14. At this time point, an oscillating circuit 4 is set immediately before actuation and the output signal Q1 of a frequency dividing circuit 5 has no change. The output of an integration circuit 12 is set H level, and an AND circuit 11 is opened with the output signal (f) of an oscillation detecting circuit 13. Thus a power-on clearing signal AC is delivered. Then the circuit 4 has oscillation and therefore the signal Q1 has a change. Then the signal (f) is set at L level to close the circuit 11, and the signal AC is set at L level. While the FF14 is set at L level with the output of the circuit 5, and the detection of power supply application is released. When the noise is mixed to the power supply, the FF14 delivers an H level signal. In this case, the signal (f) is kept at L level as long as the circuit has oscillation with the signal AC kept at L level respectively.

Title: Temperature responsive valve
Inventor: FUJIWARA KATSUJI
IPC: F16K31/70
Filed: 1982-05-21
Abstract: PURPOSE:To generate large fluctuating stress during change of shape of heat operated element by using a disk shaped element made of shape memorizing alloy. CONSTITUTION:When valve chamber 4 temperature falls to a specific level, element 71 makes martensite transformation from the original to martensite form, making small curvature. Accordingly valve 11 is pressed by pressure of the liquid on inlet port 2 side and moves away from valve seat 15 opening the valve 5. Liquid flows from inlet port 2, through valve opening 5 into valve chamber 4 and flows out of exit port 3. During this time, the temperatur of the liquid rises. When the temperature reaches a specific level, element 71 changes its shape in the reverse way to the original making great curvature. This drives valve 11 onto valve seat 15, closing valve 5.

Filed: 1988-04-08
Abstract: PURPOSE:To prevent power supply pad from being damaged and to improve reliability by changing the width of power supply wiring in accordance with the density of current for keeping current supplied to the power, supply pad to be within an allowable current. CONSTITUTION:Current of a power supply pad 4b where the maximum current flows to can be reduced by making thinner at least neighboring second power supply wires 6b and 6d of a second power supply wiring 6c directly below a power supply pad 4b.

Thus, one part of current flowing to the power, supply pad 4b can be distributed to other power supply pad 4a, etc., to prevent current exceeding an allowable range from flowing.
