Title: Switching circuit
Inventor: SAKAMOTO TOSHIKI
IPC: H03K17/22
Filed: 1993-01-26
Abstract: PURPOSE:To obtain a stable output signal without being affected by a power-ON noise and a power source noise by connecting an output electric pole between the input side of an output switching part and a power source, and providing a PNP bipolar transistor(TR) whose capacity is connected to an input electric pole. CONSTITUTION:An emitter as one of the output electric poles of the PNP bipolar TR 21 is connected to a power source terminal Vcc, a collector as one of the remaining electric poles is connected to the uninverted input terminal (+) of a comparator 1, and a base as the input electrode is open. Consequently, when electric power Vcc is supplied, the TR 21 turns ON since the base of the TR 21 is installed through capacitance of several pF to supply the electric power from the power source to the uninverted input terminal A of the comparator 1, and consequently the potential at the point A rises without any time delay, so that the potential at a point B will not be higher than the potential at the point A. Therefore, an output voltage Vo becomes neither high nor low.

Title: Semiconductor memory device
Inventor: MIYAMOTO EIJI
IPC: G11C29/00
Filed: 1989-02-09
Abstract: PURPOSE:To protect a word shunt line against disconnection caused by electromigration by a method wherein adjacent word shunt lines are formed vertically separated from each other interposing an insulating layer between them. CONSTITUTION:Word lines 8 and 8' are formed on an Si substrate 3 through the intermediary of an insulating film 13. When word shunt lines 10 and 10' adjacent to each other through the intermediary of pad electrodes 11 and 11' are formed, the shunt lines 10 and 10' are vertically separated from each other through the insulating film 22 and the electrode 12 or formed at different levels. Therefore, the shunt lines 10 and 10' are protected against disconnection due to electromigration or the stress caused by an interlaminar insulating film by making the shunt lines 10 and 10' large in width. As the coupling capacitance between the shunt lines 10 and 10' is small, an abnormal read-write operation can be prevented. Moreover, when a column address decoder selects two or more shunt lines at a time, the decoder is made to have a selection logic in which the load of the selected shunt line is always constant to any address, whereby a memory device of this design can be accelerated and stabilized in access operation.

Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce the cost, size and weight of a power circuit provided with a current resonance converter which can cope with a wide range and increase the reliability of a product. SOLUTION: In a power factor improvement circuit 10, a parallel circuit LSP of choke coils LS1 /LS2 is installed and the end of the choke coil LS2 is connected through a switch S. The switch S is turned on when a 100-volt AC supply is used and is turned off when a 200-volt AC supply is used to variably control the industance of the parallel circuit LSP. By this method, when a 100-volt AC supply is used, a resonance impedance of a series resonance circuit is lowered and the lower limit regulation region is guaranteed. And, when a 200-volt Ac supply is used, the resonance impedance of the series resonance circuit is raised and a high power factor is kept as it is and thereby a wide range can be coped with.
