Title: Product of ultraviolet light intercepting glass
Inventor: KURAMITSU OSAMU
IPC: C03C17/23
Filed: 1985-06-25
Abstract: PURPOSE:To reduce the cost and improve adhesion to glass and discoloration of films in a high-temperature atmosphere, by coating a formed glass article at a high temperature just after forming with a coating material containing an organometallic compound. CONSTITUTION:A formed glass article at a high temperature just after forming is coated with a coating material containing an organometallic compound at least once to produce the aimed ultraviolet light intercepting glass product. The formed glass article just after forming has preferably 300-700 deg.C body glass temperature. Normally, the body glass temperature of the formed glass article just after forming is <=700 deg.C, and rapidly decreased by allowing the article to stand. If the body glass temperature becomes <300 deg.C, the cracking of the body glass results. Ce, Fe, Ti and V are preferred for the metal in the above-mentioned organometallic compound. The reason why the organometallic compound is used is that the film of a metal oxide having good adhesion can be readily formed when applied to the formed glass article at a high temperature.

Abstract: PURPOSE:To obtain a commutator which can resist centrifugal force by forming the protrusion of a commutator chip holder such that the cross sectional shape thereof will become narrower toward the center of the commutator chip holder. CONSTITUTION:A commutator chip holder 1 is composed of ceramic where protrusions 10 are formed at the outer circumferential section and proper number of axially extending grooves 1a are provided. The protrusion 10 is formed such that the cross sectional shape thereof will become narrower toward the center of the commutator chip holder 1, and a commutator chip 2 is pressure inserted into the protrusion 10. A stopper member 3 is inserted into the holding groove 1a with the opposite end sections 21 of the commutator chip 2 being pressed to the side section 12 of the holding groove 1a. Even when the commutator chip holder 1 rotates to exert centrifugal force onto the stop member 3, function of the centrifugal force is limited because the outside face at the end section 21 of the commutator chip 2 is made wider toward the center. By such arrangement, a commutator having excellent resistance against heat and centrifugal force due to the rotation can be realized through a simple structure.
