Title: Pulley device with built-in one-way clutch for alternator and manufacture thereof
Inventor: OKUMA TAKEO
IPC: F16H55/36
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To suppress unevenness in a radial gap in one support bearing being a cylinder roller bearing to low value and besides and to sufficiently ensure a life of the bearing of a support bearing. SOLUTION: An inner ring 26 of which one support bearing 14 consists is formed simply in a cylindrical shape having no flange. After this inner ring 26 is securely and externally fitted in the outer peripheral surface of the end part of a sleeve 8a through shrink fit, grinding is applied on the outer peripheral surface of the inner ring 26 to form an inner ring track 33. Grinding is applied such that the track diameter of the inner ring track 33 is adjusted to a proper value. Thus, unevenness in a radial gap in this one support bearing 14 after assembly of one support bearing 14 into the sleeve 8a and a sleeve 7b is suppressed to a low value.

Title: Production of wire printing head
Inventor: ANDO KOICHI
IPC: B41J2/25
Filed: 1992-05-21
Abstract: PURPOSE:To easily and perfectly remove the coating layer formed on the side surface of a printing wire. CONSTITUTION:The periphery of a wire matrix 21 formed of a material having large anti-breaking force is coated with a masking material to form a masking coating layer 22 and the coated wire matrix is cut into a preset length to expose the wire matrix 21 to the cut surfaces. At this time, a printing wire 11 wherein the side surface is coated with the masking material and the wire matrix 21 is exposed at both end surfaces thereof is obtained. Continuously, particles of a material having high abrasion resistance are applied to the cut surface to which the wire matrix 21 is exposed by flame spraying and fixed thereto by anchoring effect. The masking coating layer 22 is released to form the printing wire 11. Since the masking coating layer 22 is formed on the side surface of the printing wire 11, flame spraying energy is absorbed by the masking layer 22 and the fixing force of particles is reduced.
