Title: Power supply
Inventor: OKUMURA MASUSAKU
IPC: H02M7/06
Filed: 1990-01-24
Abstract: PURPOSE:To suppress voltage fluctuation by connecting a voltage response switching element in parallel with a secondary coil and initiating high frequency vibration through a transformer upon turn OFF of the switching element. CONSTITUTION:When the voltage of a secondary coil SC reaches a predetermined level, a nonlinear capacitive element C is turned OFF and current is stored in a leak inductance Ll thus producing a counter electromotive force. Consequently, the leak inductance Ll and the residual capacitance produce series resonance which is then converted through a resistance component (r) into damping oscillation. The damping oscillation is superposed as a high frequency oscillation immediately before the peak of AC voltage in order to conduct a rectifying diode D. Consequently, a current corresponding to the high frequency oscillation flows through the rectifying diode D. Peak current is relatively low at this time. By such arrangement, efficiency is improved and noise level is lowered resulting in a small diode D having a high rating.

Filed: 1992-01-30
Abstract: PURPOSE:To enable a fine pattern to be enhanced in alignment accuracy when it is formed. CONSTITUTION:Cooling devices 3 are provided coming into close contact with a semiconductor 2 on a stage 1. That the cooling device 3 is aligned with a light exposure point always and controlled is carried out taking advantage of a light exposure point, an exposure time, and a mask aperture rate. Most of light energy consumed in a photosensitive resist at light exposure is absorbed in a semiconductor substrate. Therefore, heat is generated, and the semiconductor substrate is thermally expanded. By introducing the cooling device 3, the heat is prevented from diffusing, so that the substrate can be set small in temperature distribution difference. A cooling device is positioned just under a light exposure spot, whereby the heat released at light exposure is dissipated, and consequently a semiconductor substrate can be small in temperature distribution. A semiconductor substrate can be finely controlled in temperature distribution, whereby it can be lessened in temperature distribution difference.

Abstract: PURPOSE:To surely execute interface and to simplify the device by preferentially returning a multi-address frame, which is transmitted from the terminal of a token ring network TRN standard, to a transmitting terminal while utilizing the output of the node device on the variable communication network. CONSTITUTION:When a node device 2 executes broadcasting, the input frame is inputted from an output port o7 to a FIFO 16 and an input signal identification part 15. In this case, when the input frame is a frame from the TRN terminal and the multi-address frame, it is identified by the identification part 15. In the case of the multi-address frame, it is judged by detecting the final EDEL of a frame format whether the entire multi-address frame is inputted or not. After this multi-address frame is completely received, the FIFO 16 is controlled and the multi-address frame fetched into the FIFO 16 is transmitted to an input port i7. Thus, since the multi-address frame is broadcasted to all the output ports again, the multi-address frame can be received.
