Title: Tip seal for scroll type compressor and manufacture thereof
Inventor: MATSUOKA AKIHIKO
IPC: F04C18/02
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To fill a metal die sufficiently with a resin composition so as to prevent deterioration of strength in a high requirement characteristic part by setting a gate arranged in injection molding into a specified position. SOLUTION: A tip seal 1, which is used for a scroll type compressor, provided with a rectangular cross section, and formed into a spiral shape in a plane vision, is formed by injection molding. A gate trace 2 is left in the tip seal 1 because of this injection molding. In this case, a gate in the injection molding is set within a part from 1/10 or less than 4/10 of the spiral overall length from the winding end part of the spiral shape. The gate is formed as a side gate, and the tip seal side face, in which the gate is arranged, is formed of a substantially vertical plane facing the advancing direction of molten resin in the side gate. In this way, resin composition filling performance can be improved, and deterioration of strength in a position of a high requirement characteristic such as strength of the tip seal can be prevented.

IPC: H03F1/34
Filed: 1988-06-30
Abstract: PURPOSE:To realize highly accurate and stable power amplification by amplifying a potential difference detected by means of a shunt resistance separately from the earth of a power amplifier. CONSTITUTION:An error amplifying section 11 converts an input signal and output current into a voltage and amplifies the error amount to an amplified signal and a power amplifying section 12 amplifies the power of the output of the error amplifier 11.
