Title: Manufacture of quartz oscillator
Inventor: WAKASUGI MAKOTO
IPC: H03H9/19
Filed: 1981-04-30
Abstract: PURPOSE:To suppress crystal impedance low and to stabilize an electric equivalent circuit constant by forming an electrode film while resist for electrode formation projects out of a crystal-side surface, and thus preventing a flank electrode from extending onto a main surface. CONSTITUTION:For etching a crystal wafer 5, a pattern of photoresist 5-10mum wider than the external contour of a CrAu thin film 6 serving substantially as resist is formed partially on the CrAu thin film 6. Then, the crystal wafer 5 is etched to remove parts 11, 12 and 13 unavoidable in electrode turnaround, thus forming an electrode whose flank electrode never extends onto a main surface. As a result, the principal part of the flank electrode of a tuning fork type quartz bar material never extends onto the main surface, and the crystal impedance of the quartz oscillator is suppressed low.

Title: Handrail member
Inventor: KAWAMURA KEIZO
IPC: E04F11/18
Filed: 1995-03-24
Abstract: PURPOSE: To provide a handrail section, which has excellent appearance design properties and is clasped easily without sliding, on which there is no cold feeling and in which a surface is smoothed and is difficult to be fouled, by covering the external surface of a cylindrical core material, in which projecting sections are formed to a surface, with a cylindrical elastic material with a skin layer. CONSTITUTION: A handrail member 1 is formed of a cylindrical core material 2 and a cylindrical elastic material 3. Projecting sections 2a are arrayed and shaped in the circumferential direction of the external surface of the core material 2. The elastic material 3 is formed of a foamed layer 3a and a skin layer 3b. When the elastic material 3 is pushed from the external surface of the elastic material 3, the foamed layer 3a is sunk. Consequently, when the elastic material 3 is pushed by the bulb of a finger, the elastic material 3 is sunk along the shape of the finger, thus preventing sliding. Accordingly, the handrail member 1 is grasped easily without sliding, has no cold feeling, a surface thereof is smoothed and fouling is difficult to adhere, and can be used safely from children to the aged.
