Title: Semiconductor device and manufacture thereof
Inventor: SOMEYA TOMOYUKI
IPC: H01L29/78
Filed: 1990-11-21
Abstract: PURPOSE:To enable a side wall oxide film on a source side of a gate electrode to be thin and resistance at the source side to be reduced without preventing an electric field relaxation effect on a drain side by performing a skew anisotropic etching from the source side in a MOSFET when forming a side wall. CONSTITUTION:After a gate electrode 2 is formed on a semiconductor substrate 1, a low impurities concentration layer 3 is formed by ion implantation and an oxide film 15 is deposited by a normal CVD method. Then, by changing an angle of a substrate and performing anisotropic dry etching, a side wall oxide film 3 and a side wall oxide film 4 which are asymmetrical left and right are formed. High impurities concentration layers 7 and 8 are formed in self-aligned manner on the semiconductor substrate 1 with the gate electrode 2 and the side wall oxide films 3 and 4 as a mask. A MOS transistor is formed here, to prevent deterioration of an element due to hot electron with a side where the side wall oxide film 4 is thin and resistance is reduced as a source 8 and a side where the side wall oxide film 3 is thick and electric field is relaxed as a drain 7.

Title: Pocket dosimeter with alarm function
Inventor: TANOUE TOSHIYA
IPC: G01T1/17
Filed: 1989-12-01
Abstract: PURPOSE:To use a comparator which is slow in response speed by resetting a peak held when conversion into a digital signal by comparator A connected additionally to an amplifier is completed. CONSTITUTION:Pulses outputted by the amplifier 3 are converted into the digital signal A exceeding a discrimination level A of the added comparator. At the same time, the pulses have peaks held by peak holding circuits 6 - 10. When the conversion into the digital signal by the added comparator 7 is completed, the held peaks are eliminated with the leading edge of the digital signal A. Therefore, the time the peak hole signal exceeds the discrimination level B becomes long and even the comparator which is slow in response speed operates stably at all times to perform conversion into a digital signal B.

Abstract: PURPOSE:To obtain a downsized, lightweight recorder which has a carriage that moves along a recording medium and is equipped with two or more recording devices, by a method wherein the distance in the carriage traveling direction between adjacent head elements of the recording devices is specified to decrease the traveling range of the carriage. CONSTITUTION:A recording mechanism of an ink jet recorder has a carriage 6 that reciprocally travels along a guide rail and is equipped with two or more recording heads 8 (two in the case of the drawing) as recording devices.
