Title: Analog switch circuit
Inventor: KANAYAMA MASABUMI
IPC: H03K17/687
Filed: 1990-03-07
Abstract: PURPOSE:To reduce feed through when an analog switch is turned off and the error of the hold voltage of a sample and hold circuit by connecting plural analog switches in parallel, and deviating the off timing of each switch little by little. CONSTITUTION:The switches S1 and S2 consisting two transmission gates with different size are connected in parallel between an input terminal IN and an output terminal OUT. In this circuit, the off timing of the switches S1 and S2 are deviated from each other little by little. Therefore, the feed through of the switch with earlier off timing is erased by another switch that is not turned on yet, and the feed through due to the turning off of the switch finally remains. In such a way, it is possible to reduce the feed through when the analog switch is turned off, and to reduce the error of the hold voltage of the sample-and-hold circuit.

Filed: 1982-03-31
Abstract: PURPOSE:To make it possible to easily carry out an emission spectroanalysis employing an inductive coupling plasma light source device (ICP), by automating the operation for effecting impedance matching between a power source and a load in the ICP. CONSTITUTION:The output of a high-frequency power source 1 is sent to a matching box 3 through a coaxial cable.

Title: Thin film transistor array substrate
Inventor: WATANABE TAKAHIKO
IPC: G02F1/1345
Filed: 1989-03-06
Abstract: PURPOSE:To decrease short-circuit defects of an internal element and to take an electrostatic countermeasure for the internal element by removing upper-layer wiring on a cutting part, and employing through-hole wiring for the upper-layer wiring and lower-layer wiring. CONSTITUTION:The lower-layer wiring 4 is formed on a glass substrate 6 and an inter-layer insulating film 5 is formed; and a through hole 3 is formed by etching in the insulating film on the lower-layer wiring and then wiring 1 is formed of Cr.

IPC: B41J2/055
Filed: 1991-03-19
Abstract: PURPOSE:To drive an ink jet printer head so that ink emitting quantity is enhanced and the flight direction of an ink droplet can be corrected. CONSTITUTION:By applying voltage of constant potential to the electrode 5 of a pressure chamber 3 for a definite time in order to emit the ink in the pressure chamber, the decay speed of the pressure in the pressure chamber 3 accompanied by the emission of ink is decreased and the decay of the flight speed of an ink droplet on the side of the tail part thereof is relaxed.

Abstract: PURPOSE:To protect a motor against an overload without separately mounting a temperature detector by detecting the temperature of a winding by utilizing the temperature dependency of the output of a pole position detector, and turning a drive circuit OFF when it is set temperature or higher. CONSTITUTION:Output signals of Hall elements 3a-3c for detecting the position of the pole 2d of a Hall motor 2 are input to a control system which has a shaper 7, a distribution signal circuit 8 and a base drive circuit 9 for controlling the conduction of a transistor of a main circuit inverter 1b, and also input to an overload detector 6. Since the absolute values of the outputs of the Hall element vary in response to the temperature around the elements, the absolute values are produced, and compared by a comparator 6b with the value corresponding to the reference set temperature. When exceeding the set value, it is judged as being abnormal overheated state due to the overload, and the power supply from the main circuit 1 is stopped.
