Title: Molding die
Inventor: OOTANI MASUHISA
IPC: B29C43/36
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To improve the pollution recovery ratio of a molding by a method wherein the surface of a cavity for molding the molding is etched by chemical treatment and the etched surface is treated by blasting through the jetting of particulates. SOLUTION: In a molding die for molding a molding, the surface of a cavity is etched by chemical treatment and then the etched surface is treated by blasting with particulates having the particle diameter of 20-200μm. As a result, the portion having undercuts 1 and the portion having sharp corners 2 in the surface of the cavity are rounded, resulting in allowing to easily remove even when pollutant adheres to the surface and improve the pollution recovery ratio of the molding. Accordingly, by employing this molding die, the moldings excellent in pollution resistance and improved in external designedness such as floor material, wall material, bathtub or the like can be molded.

Abstract: PURPOSE:To eliminate the vertical error of a sensor and to make the measurement of the sensor accurate by directly communicating the 1st housing chamber housing a biaxial gimbal mechanism and sensor main body with the 2nd housing chambers housing hair springs which supply power to the sensor main body and have very small diameters. CONSTITUTION:This device for holding the vertical axis of a sensor is constituted in such a way that the inside of its casing 1 is divided into three chambers by means of two partition plates 11 and a biaxial gimbal mechanism 3 and sensor main body (magnetic sensor) 4 held by the mechanism 3 are housed in the 1st housing chamber 2 at the center. The 2nd housing chambers 5 on both sides of the chamber 2 house hair springs 6 for supplying power. The casing 1 is put in a, for example, discoid outer case when this device is used.
