Title: Manufacture of synchronizer ring
Inventor: SAITO KENJI
IPC: F16D23/06
Filed: 1993-08-30
Abstract: PURPOSE:To dispense with use of an expensive edge tool, form a continuous flame spraying layer, and heighten the close contact strength by carrying out broach work on grooves before cementation quenching is carried out, carrying out grinding work on the conical friction surfaces and back faces from which cementation is prevented, and lastly carrying out flame spraying of flame spraying metal such as molybdenum. CONSTITUTION:Before cementation quenching is carried out, on the whole circumference of the friction surfaces 22, broach work is carried out on grooves 23 in parallel with the rotation axis of a synchronizer ring 21 in succession to machine work of the conical friction surfaces 22. Thereby, use of a cemented carbide tool can be dispensed with, and the device life of an edge tool is lengthened, and productivity is also improved. After the broach work and the cementation quenching are carried out, flame spraying of tungsten or the like is carried out, and since a continuous flame spraying coating film 27 is formed on the whole surfaces of the grooves 23 and projections 24, close contact strength of this flame spraying layer 27 is heightened, and durability is improved.

Filed: 1985-10-23
Abstract: PURPOSE:To improve the focus characteristic by forming a field producing means such that a plastic holder having a required coefficient of linear expansion is fitted over a tubular body to hold a pair of ring magnets, thereby performing temperature compensation. CONSTITUTION:Main focus electron lens of a field focus type cathod-ray tube is formed with a magnetic lens formed by a field producing means 5 arranged at the outside of the neck section 3 of a tubular body 1. Here, a plastic holder 6 having required coefficient of linear expansion is fitted over the neck section 3 to hold a pair of ring magnets 7A, 7B. The gap G between the ring magnets 7A, 7B is varied through expansion/contraction of the holder 6 caused through temperature variation, thus compensating variation of the flux density of each magnet. Consequently, variation of the focus characteristic can be suppressed effectively even upon temperature variation by selecting the temperature coefficients of the magnets 7A, 7B and the coefficient of linear expansion of the holder 6.
