Patent JP-S62207075-A (JP)
Title: Semiconductor integrated circuit
Inventor: KURIHARA HIROSUKE
IPC: H04N5/335
Filed: 1986-03-07
Abstract: PURPOSE:To reduce a fixed pattern noise by providing a coupling capacity element to absorb field through charges in parallel with a reset switch, thereby to suppress fluctuation of the input-terminal potential reset at a reference potential even when the value of capacitance seen from the input terminal is in variance. CONSTITUTION:One terminal of the coupling capacitor CC is connected with the input terminal of a read circuit. To the other terminal of the capacitor CC for the driving voltage VGR of the reset switch 6, a timing potential VC is impressed. Following the turning-ON of the switch 6 and after the turning- OFF of the switch 6 upon completion of the reset, the latter-mentioned terminal of the capacitor CC is held at the same potential as the reference potential VR until a time DELTAt lapses. Therefore, there is no charge in the capacitor CC during the reset. Immediately after the completion of the reset, the charges are injected to the capacitor CC from an input terminal 2 during the time DELTAt above. By setting the value of the capacitor CC so that the injected charges come equal in amount with the field-through charges, the potential of the input terminal 2 does not virtually drift from the reference potential VR.

Title: Balanced signal pulsating circuit
Inventor: MUTO HIROSHI
IPC: G11B5/09
Filed: 1986-03-05
Abstract: PURPOSE:To attain highly accurate pulsating processing by separating an absolute value circuit from a differentiation circuit so as to keep the symmetry of the waveform. CONSTITUTION:An absolute value circuit 1 receiving balanced input signals A, A' from a reproducing signal generating source 4 outputs balanced output signals B, C whose phase are opposite to each other. The signals are nearly completely symmetrical and the absolute value of the signal is represented independently of the polarity of the input signal. The signals B, C and fed to a differential differentiation circuit 2, which outputs nearly completely symmetrical differentiation signals D, E. A bias higher by a potential difference DELTAV is given to the differentiation waveform D than that to the differentiation waveform E to form waveforms F, G respectively, which are given to a comparator 6. The comparator 6 gives a pulse voltage output only when the level of the waveform G is higher than the level of the waveform F. Since the waveforms F, G are nearly completely symmetrical, the position of the pulsated output pulse is made stable. Thus, the highly accurate pulsating is applied.

Title: Water take-in valve
Inventor: NAGAOKA AKIRA
IPC: F16K47/02
Filed: 1987-03-04
Abstract: PURPOSE:To prevent water hammer phenomenon by pressing a main valve body against a bypass valve body by means of a coil spring arranged between the main valve body and a valve rod. CONSTITUTION:When an operating handle 37 is rotated to push down a valve rod 25, a bypass valve body 27 lowers with respect to a main valve body 20 so as to open a bypass 24. Since primary water pressure functioning onto the under face of the main valve body 27 is set higher than the initial repelling force of a coil spring 31 for pressing the upper face of the main valve body 27 downward, the main valve body 27 is not opened. When the secondary water pressure is equalized to the primary water pressure, the valve is brought into open state, i.e. water take-in state, by push-down force of a valve rod 25 produced by the operating handle 37.
