Abstract: PURPOSE:To increase the life of a tool for Al-Si alloy and printing board work by providing a coating layer of diamond of more than 0.1mum on a base body consisting of sintered body of Si3N4 including MgO, etc., by 0.01-30wt.% totalling less than 50wt.%. CONSTITUTION:The base body of sintered body of Si3N4 has a higher rigidity than an ultra-rigid alloy and a good abrasion resistance, and it has an almost similar linear expansion coefficient to diamond, so residual stress is not generated at a coating layer, so a coating layer having a good attachment property can be formed if the layer thickness is more than 20mum. However, the layer thickness of less than 0.1mum is not effective, or that exceeding 200mum is uneconomical. Though Si3N4 has a bad sintering property, a sufficiently dense and rigid sintered body can be obtained by adding at least one of MgO, Y2O3, Al2O3, AlN, a high temperature resistance is improved by adding ZrO2, HfO2, an abrasion resistance is improved by adding TiC, TiN, B4C, BN, TiB2, where the quantity of addition shall be within a range of 0.01-30wt.% for each, and if the total exceeds 50wt.%, the strength of Si3N4 sintered body is decreased.

Abstract: PURPOSE:To obtain proper storage time at all times in a photoelectric converter for automatic focus detection of a camera, by reading out simultaneously charge of a light current stored in a storage circuit in relation to the detected timing. CONSTITUTION:When a charge signal is supplied from outside to an input terminal 14, a gate 9-1 conducts and a condenser 8-1 is charged upto power source voltage. Consequently, potential of output point Y-1 of buffers 10-1, 11-1 is also raised, and the output is led to a comparator 18 through a diode 12-1. Out of buffer output points of photoelectric conversion circuits 6-1-6-N, one having the highest potential appears first in the signal input terminal 15 of the comparator, and a reference potential source is connected to other input terminals. The output of the comparator is inverted when the maximum output signal of the photoelectric conversion circuit arrives at a comparison level. This is detected by a control circuit and sends out a transfer pulse to a terminal 17.

Title: Optoelectronic integrated circuit
Inventor: SAWADA SOSAKU
IPC: H01L29/737
Filed: 1993-05-17
Abstract: PURPOSE:To provide an optoelectronic integrated circuit for receiving light which is suppressed in noise current and improved in sensitivity. CONSTITUTION:The integrated circuit contains a photoreceptor element and heterojunction bipolar transistor group formed on a substrate 300. The semiconductor material forming the light absorbing layer 120 of the photoreceptor element is selected so that its band-gap value can become larger than that of the semiconductor material forming the base layers 213 of the bipolar transistors. As a result, no light carrier is generated in the layer 120 and the generation of a noise current is suppressed even when the layer 120 is irradiated with the light caused by the radiation recombination of base currents in base layers at the operating time of the bipolar transistors.
