Title: Driving device for switching element
Inventor: KOMATSU SHUNICHI
IPC: H03K17/567
Filed: 1989-09-27
Abstract: PURPOSE:To make suppression of a peak voltage compromise with the reduction of switching loss between a drain and a source by changing the impedance of the transistor for gate discharge of a field effect transistor(FET) that is a switching element corresponding to an input voltage. CONSTITUTION:The transistor(TR) 4 is an N-channel FET for the CGS extraction (for gate discharge) of the FET TR1 that is the switching element, and resistor(R) 2, 3 correct the gate driving voltage of the FET TR4 corresponding to the input voltage. When the input voltage is high, the TR4 is used in a linear area, and the impedance between the drain and the source can be increased. Therefore, the VDS waveform of the FET TR1 is rounded when the TR1 is turned off, which suppressed a VDS peak voltage. Adversely, when the input voltage is low, the TR4 is used in a saturation area, then, the impedance between the drain and the source can be decreased. Thereby, the switching loss or the TR1 when the TR1 is turned off can be reduced.

Filed: 1987-10-02
Abstract: PURPOSE:To achieve an always stable detection of a congestion level, by providing a lighting controller for an elevator hall to control a difference between a reference and imaging information within a specified value when it continues to exceed the specified value for a specified time of period. CONSTITUTION:The state of a vacant elevator hall is taken with a TV camera 1 on reference lighting conditions and stored into a video memory 3 through an A/D converter 2. Under the control of a CPU 5, the contents of the memory 3 are trans ferred through an input port 8 to be compared with a reference of a data memory 7 per pixel. When the number of pixels with the brightness exceeding a specified value is counted to calculate a congestion level and congestion level information 9a is sent to an elevator controller 13 from an output port 9. As changes in the bright ness of image pick up information continue for a specified time length, a control output 9b corresponding to the difference with the reference value is outputted to a controller 11 through the output port 9 to vary the brightness of lighting whereby the difference in the brightness between the reference and the image pick up informa tion is controlled within the specified value. This permits automatic correction of the brightness of the elevator hall thereby enabling highly accurate detection of the congestion level.

Abstract: PURPOSE:To take a test without disturbing the use of a channel circuit in exchange connection service by demultiplexing and selecting a time-division multiple output signal and then monitoring its polarity bit, and detecting whether a fault occurs on a channel or not. CONSTITUTION:A selecting circuit 12 selects a signal to be tested among signals obtained by demultiplexing the channel output of a channel switch 2 and inputs the signal to a channel monitoring circuit 13. The separating circuit 14 of the circuit 13 separates the polarity bit from the inputted time-division multiple signal and inputs it to a polarity counting circuit 15. The circuit 15 adds bits with the positive polarity when they are inputted from the circuit 14 while a reset pulse with a specific period is inputted from a period pulse generating circuit 16 and subtracts bits with the negative polarity when they are inputted. When mean values in a long period are calculated, the time division multiple signal has nearly equal generation rates of positive and negative polarity bits and the counted value of the circuit 15 is nearly zero, but when the counted value exceeds a specific value, the circuit enters an overflow state and outputs a fault detection signal from a terminal 5.
