IPC: H02M3/28
Filed: 1985-03-29
Abstract: PURPOSE:To prevent a switching semiconductor element from damaging due to the saturation of a transformer by connecting the output of a double voltage rectifying and smoothing circuit connected with the tertiary winding of the transformer with a load through a variable impedance circuit. CONSTITUTION:When operated in a normal state, a variable impedance circuit 8 is driven by a detection drive circuit 7, and an internal impedance in substantially zero. However, when the voltage of a capacitor c3, i.e., the output voltage V0 is remarkably low as compared with the normal state, the voltage VC3 of a capacitor C3 is detected by the circuit 7, the internal impedance of the circuit 8 is varied in response t the voltage to always maintain the VC3 to sufficiently avoid the saturation of a transformer T, thereby continuing the operation in the circuit.

Title: Information transfer system
Inventor: TOTANI KENICHI
IPC: G06F13/00
Filed: 1995-03-27
Abstract: PURPOSE: To apply the inexpensive DRAM of large capacity by using the DRAM instead of an SRAM for a time slot(TS) table. CONSTITUTION: A TBL is a TS table and a DRAM is used. Even though it is omitted here, it is assumed that there exists a circuit constitution for accessing the DRAM every time a DRAM address is changed. Generally, a TS number in a frame is closed in the process of a frame processing and a sequential number is supplied. At the time of the frame processing, the sequential TS number is defined as an address and the access of extracting processing information from the DRAM is executed. Since the access is the access to the address for which refreshing is required, the need of the refreshing at the time of the frame processing is eliminated. Then, by executing DRAM access by utilizing a circuit for generating the TS number even at the time other than the time of the frame processing, the application of the DRAM is realized without an independent refreshing circuit.

Abstract: PURPOSE: To can excellent convenience efficiency by having the same nozzle position while a user is the same, and having no use for a setting a water discharging position again without changing the water discharging position of the nozzle while a sitting state is continued. CONSTITUTION: After a nozzle position adjusting button 13i is controlled to push the hips washing button 13a, when the hips washing button 13a is pushed again, a washing position is maintained on the basis of a detection signal from a sitting sensor 15a. When a user sits over again on a closet seat, even if the user slightly leaves the seat, the sensor decides that he or she is the same one when he or she sits on the closet seat over a specific period of time, and the nozzle position is maintained. Then, based on the detection signal of the sitting sensor 15a, when the sensor decides that' the user is not the same one, a water discharging position of the washing nozzle is changed to correspond to an unspecific user. Accordingly, a device having no use for readjusting the water discharging position can be formed.
