Title: Crystal oscillator
Inventor: YAMASHINA MIKIHIKO
IPC: H03H9/13
Filed: 1978-09-20
Abstract: PURPOSE:To suppress the secondary resonance response by adding the mass at the intersection between the end face and the center line passing through the center of the opposing end faces of the square plate and then giving the adjustment within the range which does not affect the main resonance. CONSTITUTION:Mass 15 and 15' are added to the intersections between end faces 14 and 14' and the center line passing through the center of opposing end faces 14 and 14' of square plate 11. The mass is the material which features the viscosity and functions as the mechanical resistance, and is composed of the bonding agent, the coating material and the like. Thus the adjustment can be given properly within the range which does not affect the main resonance. As a result, the secondary resonance response can be suppressed.

Title: Preparation of diamond
Inventor: NISHIDA SHIGEO
IPC: C30B29/04
Filed: 1982-07-05
Abstract: PURPOSE:In precipitating liberated atomic carbon, to prepare a large amount of diamond easily, by making a paraffinic hydrocarbon and hyrogen molecule exist in a gaseous state. CONSTITUTION:Liberated atomic carbon evolved by a well-known method such as discharge of carbon electrode is sent directly or by a carrier gas to a precipitating part. The precipitating part is previously packed with one or more of a paraffinic hydrocarbon atom and hydrogen molecule having a catalytic effect as a medium in a gaseous state. In the operation, the temperature of the precipitating part can be freely controlled independently of the evolving part of the atomic carbon, and carbon atom is agglomerated at the precipitating part, to give diamond. Consequently, diamond can be prepared under the temperature and pressure conditions of quasi-stable range of diamond. Seed crystal is not necessarily required by this method, as it is required by a conventional method, and a large amount of diamond is prepared easily.

IPC: H01H15/04
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To reduce infiltration of a flux into the inside at soldering time to a printed circuit board, and reduce influence of heat of solder by setting a pulling-out place from a main body box body of leads of an electronic part having the leads soldered to the circuit board by being pulled outside the main body box body, to a ceiling surface side position distant from the bottom surface side where the main body box body faces to the circuit board. SOLUTION: A pulling-out section 25 from a main box body 20 of leads 3 and 4 soldered to a printed circuit board 1 is set to a ceiling surface side position distant from the bottom surface side where the main box body 20 faces the printed circuit board 1. Therefore, when a slide switch 2 is soldered to the printed circuit board 1, rise by capillary phenomenon along the leads 3 and 4 of a flux used at soldering time hardly takes place, and can be prevented from entering the main body box body 20. Since a leg length of the leads 3 and 4 becomes long, heat of solder at soldering time is hardly transmitted to the main body box body 20 through the leads 3 and 4, and thermal deformation of a body part 21 and a bottom part 23 can be avoided.
