Title: Composite plied substrate for polishing disc
Inventor: MOCHIZUKI HIDEO
IPC: B24D11/00
Filed: 1984-02-24
Abstract: PURPOSE:To maintain the uniform cutting performance up to the near center of a polishing disc by forming a polishing disc substrate by plying nonwoven fabrics and the cloth material having rough weaving degree, thus reducing the hygroscopic performance of the polishing disc made of the above-described substrate. CONSTITUTION:A polishing-disc substrate is formed by superposing the nonwoven fabric impregnated with resin (e.g., phenol resin) and the cloth material having rough weaving degree which is impregnated with resin (e.g., phenol resin) and press-attaching these two fabrics under pressure by a hot press. The rough weaving degree side of the substrate is applied with resin, and polishing grains are attached, and then resin is applied again, and the fabric is heated and hardened to form a polishing disc. The hygroscpoic performance of the polishing disc thus formed is markedly reduced, and the abrasion of the substrate is generated, accompanied by the falling-off of the grinding grains on the peripheral part of the disc through grinding work, and the peripheral part having the superior cutting performance can be always exposed, accompanied by the abrasion, and the use of the disc with the uniform cutting performance up to the center of the disc is permitted.

Title: Laser diode module
Inventor: ONODERA TAKAYUKI
IPC: H01S5/022
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To reduce distortion of a waveform transmitted through a long fiber by using an optical device having a small insertion loss in a short wavelength and a large insertion loss at a long wavelength, in an optical system of a laser diode module. SOLUTION: When the luminescent center wavelength of an optical-modulator- built-in DFB-LD device 1 is set at a wavelength region such that an insertion loss is small in a short wavelength side and large in a long wavelength side, small variations in the wavelength during modulation increases optical output relatively, at a digital modulated waveform rising and decreases it relatively at the digital modulated waveform falling, which therefore can provide a steep rising waveform and a steep falling waveform. This steep rising/falling characteristics in the digital modulated waveform can reproduce an optical signal having less error in a receiver for converting an optical signal to an electrical signal, even if an inputted optical signal is low in level.

Abstract: PURPOSE:To obtain a safe electrothermal cooker which does not fire even if a thermostat is in trouble and further an overheating preventing means does not work normally by forming a spring of a shape memory alloy which will contract when temperature rises too high, so that it can energize a hook lever to engage with a lid. CONSTITUTION:Free length of a spring 15 made of a shape memory alloy at normal cooking time is set at value (A) and free length at overheating time is at value (B). If the spring 15 is arranged not to energize a hook lever 11 when its free length is of the value (B), the spring 15 contracts when temperature rises too high. A lid 7 always is arranged to act in opening direction by means of a spring member 10, so that the hook lever 11 engages with an engaging part 20. When the lid 7 is opened, heat accumulated within the body 1 by constant power supply from a heating unit 21 disperses from an opening made in the upper surface of the body 1. Further a pan 3 works as radiating fin of the heating unit 21, and therefore, the heating and radiating of the heating unit 21 reaches equivalence. Thus the rising of temperature of the heating unit 21 stops to prevent firing.
