Patent JP-H04178022-A (JP)
Title: Field effect transistor logic circuit
Inventor: MAETA TADASHI
IPC: H03K19/0952
Filed: 1990-11-13
Abstract: PURPOSE:To decrease dispersion in a delay time due to fluctuation of temperature by obtaining a gate bias of a buffer section current source FET from a reference voltage generating circuit. CONSTITUTION:When an H level is inputted to an input terminal 10, a node 11 goes to an L level, the drive capability of a FET 3 is tentatively reduced and the charge in a load capacitor connecting to an output terminal 20 is discharged by a FET 5. The current in this case depends on a gate bias of the FET. The gate bias is obtained from a reference power supply generating circuit and the level is maximized at a threshold voltage decided by the parameter of the circuit. A current fluctuation of a current source FET caused by the fluctuation of the threshold level due to temperature fluctuation is suppressed small by setting the design value of the threshold voltage to this value. As a result, the delay time is immune to the effect of temperature fluctuation.

Title: Voltage monitoring apparatus
Inventor: TSUKUDA YOSHIHIRO
IPC: G01R31/36
Filed: 1987-12-04
Abstract: PURPOSE:To make an apparatus compact in a simple constitution and to reduce a cost, by counting the elapsed time period from a time point when a voltage which is outputted from a battery has become less than a specified voltage, and outputting the detected signal when a preset time period has elapsed. CONSTITUTION:A battery 1, which outputs a specified DC voltage, supplies the specified DC voltage to a voltage detector 3 and a control part 5. The voltage detector 3 identifies that the voltage of the battery 1 has reached a first warning level, where the normal voltage decreases to a value less than a specified voltage. The control part 5 is composed of a counter 7, a reference clock generating circuit 9 and a control circuit 11. The output terminal of the voltage detector 3 is connected to the counter 7 and the control circuit 11. A detected signal A, which indicates the decrease in voltage of the battery 1 down to the first warning level, is issued to a reset terminal CL of the counter 7 and to the control circuit 11 at the same time. When the counter 7 receives the detected signal A, counted value is reset, and the elapsed time period is measured. The counter 7 sends the data of the elapsed time period to the control circuit 11. The control circuit 11 drives a display part 13 so as to display the reduction in voltage.

Title: Active matrix liquid crystal display element
Inventor: HASHIMOTO KAZUYA
IPC: G02F1/1368
Filed: 1994-12-12
Abstract: PURPOSE: To easily convert the white defect pixel of a liquid crystal display element of a north white mode in which the central value of a source voltage is set equal to a common voltage into a black defect. CONSTITUTION: A metallic layer 29 for welding is formed on a storage capacitor electrode part 4a-1 facing a gate bus Gi+1 of a pixel electrode 4a.

Abstract: PURPOSE:To automate the sugar-coating process by measuring the weight of a sample tablet in the respective undercoating, overcoating and finish-coating stages constituting the sugar-coating process, and controlling the sugar-coating process by a controller based on the results. CONSTITUTION:The sugar-coating process for a tablet consists of the undercoating stage, overcoating stage and finish-coating stage in the preset number of cycles in a coating pan 1. A sample tablet is taken out from the pan 1 in each stage, and the weight is measured by a weigher 7. The measured values are sent to the controller 8. When the measured values are within the allowable weight range, the stage is continued in the preset number of cycles or finished by the controller 8. When the measured values are beyond the allowable weight range, a control system by weight measurement is applied in preference to the cycle control system. By this method, whether the stage proceeds to the succeeding stage or not is automatically judged.

Abstract: PURPOSE:To facilitate regulation of pinching force of a driven roller with respect to a drive roller, in a paper currency feeding mechanism, by setting pinching force of the driven roller in the central section lower than that of the side driven roller. CONSTITUTION:A bracket 37 is arranged above a carry path substrate 1 and forming a paper sheet carry path 5.
