Title: Piston ring
Inventor: TAKIGUCHI KATSUMI
IPC: C23C14/06
Filed: 1986-02-13
Abstract: PURPOSE:To improve closely contact performance and wear resistance, by coating a relatively large amount of metal chromium at portion near a base material of a piston ring, and coating a relative large amount of chromium nitride on a sliding surface of the piston ring. CONSTITUTION:A water-cooled copper crucible 6 containing a metal 5 as an evaporation source is located below a base material 1. Electron beam emitted from an electron gun 8 is collected and irradiated onto the metal 5 of the evaporation source. Then, pressure is reduced, and the metal 5 is heated to be evaporated. The evaporated metal 5 is deposited on the base material 1 to form a base layer having a predetermined thickness. Thereafter, a nitrogen gas is introduced into a vacuum vessel 4 to react the nitrogen gas with the evaporated metal 5 and form a film of metal nitride onto the base material 1. Accordingly, a relatively large amount of chromium nitride is coated on an outer peripheral sliding surface of the piston ring, and a relatively large amount of metal chromium is coated on a portion near the base material 1, thus improving closely contact performance and wear resistance.

Title: Method of adjusting tape driving device
Inventor: HIRASAKA HISAKADO
IPC: G11B20/14
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To find such an adjusting value of a PLL circuit as it stably operates to a signal input at the time of being defective and searching at a double speed.
