Title: Heat dissipation unit for cooling heat generating component
Inventor: YAMAMOTO MASAAKI
IPC: H01L23/427
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To enhance heat dissipation characteristics by bending the side face part of a heat absorbing plate to form a wall face and disposing a heat generating component in the inside of the heat absorbing plate forming the wall face thereby absorbing heat generated from the component efficiently. SOLUTION: The heat dissipation unit for cooling a heat generating component absorbs heat generated from a component 40 through a heat absorbing plate 10, transports the heat though a heat pipe 20 and then dissipating the heat to the outside of a housing 50 by turning a fan 30. Since the side face part of the heat absorbing plate 10 is bent to form a wall face 15 and the heat generating component 40 is disposed in the inside of the heat absorbing plate 10, heat generated from the component 40 can be absorbed efficiently. Furthermore, since a wall face 15 is formed in the heat absorbing plate 10, the inside of the heat absorbing plate 10 functions as a duct for accelerating air flow and thereby the heat dissipation characteristics are enhanced.

Title: Fm receiver
Inventor: SHINOZAKI EIJI
IPC: H04B1/16
Filed: 1985-02-28
Abstract: PURPOSE:To decrease noise at no input or a weak input by applying feedback to a selective amplifier of an FM receiver. CONSTITUTION:The selective amplifier 1 and an attenuator 3 feeding back the output of the amplifier to an input of the amplifier 1 while attenuating it are formed so as to oscillate a signal in a prescribed frequency near the center frequency f0 of the amplifier 1.

Filed: 1987-02-24
Abstract: PURPOSE:To make physical property balancing of dispersion, rigidity and shock resistance of an inorganic filler favorable, by a method wherein the inorganic filler is pulverized and surface-treated with a surface treatment agent, granulation is performed by compounding a specific quantity of polyolefin and the granulated polyolefin resin and a granular or pellet polyolefin resin are compounded at a specific ratio with each other. CONSTITUTION:An inorganic filler is pulverized and surface-treated with a surface treatment agent in a pulverizer, and granulation is performed by an agitating granulator by compounding the treated inorganic filler with polyolefin resin at a ratio of 300-900 pts. wt. of the former per 100 pts. wt. of the latter. The granulated polyolefin resin (resin a) and the granular or pellet polyolefin resin (resin b) whose means diameter is 0.1-10mm are compounded with each other at a resin wt. ratio ranging from 1:99 to 80:20. In the case where a quantity of the inorganic filler is less than 300 pts. wt., the whole of the composition becomes rice-cake- like, through which handling turns difficult, and in the case where the same exceeds 900 pts. wt., the inorganic filler can't be granulated well. In the case where a compounding ratio between the resin (a) and the resin (b) is lower than 1:99, a loading effect of the inorganic filler is low, and in the case where the same is higher than 80:20, shock resistance is deteriorated and an external appearance is also deterioration.

Also, no information light transmits the substrate 2 and the sensor substrate 1. Therefore, loss or diffusion in the light quantity of the information light can be prevented occurring, which improves an S/N, and the satisfactory sensor output can be obtained.
