Patent JP-H06283553-A (JP)
Title: Field-effect transistor and manufacturing method thereof
Inventor: SAKAI MASAYUKI
IPC: H01L29/43
Filed: 1993-03-30
Abstract: PURPOSE:To suppress the accumulation of the holes generated in the high field region at a drain side for boosting the drain breakdown voltage. CONSTITUTION:A high concentration n type layer 3a on the source side of a field-effect transistor is encircled by a P type layer 19 so as to be grounded through the intermediary of a high cencentration P type layer 18. Through these procedures, the breakdown phenomenon mentioned as follows can be suppressed i.e., the field in the substrate on the source side is weakened by the accumulation on the source side of the holes generated on the drain side while the field on the drain side 5 is intensified by the extension of the high cencentration hole region on the drain side 5. Accordingly, within the planar type FET wherein the drain.source breakdown voltage poses a more serious problem than the gate.drain breakdown voltage, the drain-source breakdown voltage can be boosted.

Title: Electromagnetic shielding material
Inventor: HATAKEYAMA KENICHI
IPC: H05K9/00
Filed: 1989-03-23
Abstract: PURPOSE:To shield an electromagnetic wave which leaks out of a clearance section of a box body by providing a board of metal box body with a magnetic substance whose permeability has an incline which increases from an outer side of the box body toward an inner side thereof. CONSTITUTION:A metal box body board A which covers a metal box body B is provided with a magnetic substance D whose permeability has an incline which increases from an outer side of the box body toward an inner side thereof. Therefore, if a ratio of space occupied by the magnetic substance D is made larger inside the box body in correspondence with the clearance of an overlapped section C, the gradient of permeability at the clearance section can be acquired equivalently. As for an influence of the gradient of permeability concerning prevention of leakage from the clearance, strictly speaking, a propagation equation should be derived from the Maxwell's equations in a state where the permeability mu is a function of the position; however, it can be qualitatively explained by that the propagation velocity (v) is in inversely proportion to sq. rt. mu. Thereby, leakage of an electromagnetic wave from the clearance section of the box body can be restrained.

Filed: 1986-03-29
Abstract: PURPOSE:To improve the response speed of an error amplifier circuit by applying directly a voltage to a reference voltage generating circuit and an error amplifier circuit by an output voltage of a switching circuit connected to a pulse oscillator. CONSTITUTION:A switching circuit 9 is conducted or interrupted by an output pulse from the pulse oscillator 10, and when it is conductive, an output pulse rises from an operational amplifier 4 of an error amplifier circuit 5 while receiving power supply from a DC power supply Vcc based on the leading depending on its through-rate. When the switching circuit 9 is interrupted, the power supply from the DC power Vcc is stopped and the output pulse of the operational amplifier 4 falls down momentarily. Since the through-rate does not participate in the trailing of the output pulse of the operational amplifier 4, the response delay is not caused.
