Title: Phase comparing circuit
Inventor: YOSHIMURA KOUICHI
IPC: H03K5/26
Filed: 1981-07-02
Abstract: PURPOSE:To eliminate variation in DC voltage or phase comparison output by preventing charging and discharging paths of a capacitor, charged with the phase comparison output, from being formed during a period other than a phase comparison period. CONSTITUTION:A pulse signal from an input terminal 1 is integrated by a capacitor C1 and a resistance R1 and applied to the base of a transistor (TR)Q1. While a reference pulse C' is applied to the base of a TRQ5, TRs Q1 and Q2 are in operation to perform phase comparison. Only during the phase comparison period, diode bridges D2-D5 turn on to charge or discharge a capacitor C2 by a current which corresponds to the phase difference, sending the phase comparison output from a terminal 2. During a period other than the phase comparison period, the diode bridges D2-D5 turn off, so the capacitor C2 is neither charged nor discharged.

Abstract: PROBLEM TO BE SOLVED: To interpose a nozzle head with pressure for attaching it while being positioned in a predetermined nozzle direction by predetermining intermediate tightening torque at an intermediate tightened position, final torque at a final tightened position of a cap and a final rotation angle from the intermediate tightened position to the final tightened position. SOLUTION: A controller predetermines intermediate tightening torque, final tightening torque and a final rotation angle of a cap 12. A cap fastener 43 and a nozzle fastener 43 are simultaneously rotated to an intermediate tightened position of the cap 12. Then a spindle 51 is rotated without rotating the cap 12, so that only a nozzle head 13 is rotated to be positioned before from a nozzle direction by the final rotation angle. The spindle 51 is rotated by a servo motor to simultaneously rotate the cap 12 and the nozzle head 14 by the final rotation angle to position the nozzle head 13 in a predetermined nozzle direction. Thus the nozzle head can be interposed with pressure into a container body, and can be attached while being positioned in the nozzle direction.

Filed: 1990-04-19
Abstract: PURPOSE:To attain impedance matching with a pre-stage circuit after a package is inserted in an electronic circuit by providing a semi-fixed resistor in interlocking with an adjustment knob for impedance matching into a same package as an LC filter. CONSTITUTION:An adjustment knob 15 provided to an upper face of a package 11 is used to adjust a semi-fixed resistor in the inside of a filter externally.

Then a signal from a pre-stage circuit is inputted from the input terminal lead 12 and passes through the semi-fixed resistor 23 and an undesired signal component is eliminated by coils 21a, 21b and a capacitor 22. When impedance mis-matching takes place between the pre-stage circuit and the LC filter in the inside of the filter in the process as above, the adjustment knob 15 is turned externally to apply fine-adjustment to the semi-fixed resistor 23 to take impedance matching. Thus, the impedance matching with respect to the pre-stage circuit is easily implemented by using one component.

Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To prevent blooming of the readout gate section of a solid-state image pickup device, in which an impurity region for potential barrier is formed in the deep portion of a photodiode section, by suppressing the influence of thermal diffusion in the impurity region on the adjacent readout gate section. SOLUTION: An N--type impurity region 132 is formed on a P-type well layer 130, provided in the deep portion of a N-type Si substrate 110 and an N-type photoelectric conversion region 34 and a P+-type impurity region 36, both of which constitute a photodiode section 112 are successively formed on the region 132. The N--type impurity region 132 is formed in a size smaller than that of the photodiode section 112 and separated from a readout gate section 140 adjoining to the section 112 at an interval. Therefore, when the impurity region 132 is subjected to heat treatment process after ion implantation, the occurrence of potential decline in the readout gate section 140 is suppressed, and the blooming of the section 140 can be prevented so that the thermal diffusion in the impurity region 132 does not effect the gate section 140.
