IPC: H01P5/08
Filed: 1999-05-24
Abstract: PROBLEM TO BE SOLVED: To maintain state of grounding of a microwave oscillator IC, even under temperature variation and to obtain the stable oscillation frequency of the oscillator IC in a local osllation module. SOLUTION: Two upper and lower shielding cases 4 and 5 are secured to a printed board 2, which is mounted with a microwave oscillator IC1 and is connected with the oscillator IC1, holding the board 2 between them and the cases 4 and 5 obtain grounding with the board 2. The peripheral edge parts 1a of the oscillator IC1 are pressed by a plate spring 3 from the direction of the case 4 on the upper side of the oscillator IC1, to make the oscillator IC1 adhere closely to the board 2. The spring 3 has a plurality of leg parts, which press the peripheral edge parts 1a of the oscillator IC1 from the top panel part of the spring 3 and in the state extending from the top panel part in the direction of the lower part of the spring 3 and is covered on the oscillator IC1.  A difference between the expansivities of a substrate under the oscillator IC1 and the board 2 due to a temperature variation is absorbed by the spring elasticity of the spring 3, and while the ground planes of both of the substrate and the board keep contact with each other, the positions relative to the substrate and the board can be changed continuously.

Abstract: PURPOSE:To reduce running cost of gas analysis and to secure an analytical accuracy, by determining accuracy error of a standard gas from a reference gas, and correcting an analytical value for a sample gas, each time when a new standard gas is supplied. CONSTITUTION:After a prescribed volume of a standard gas G3' was introduced into a gaschromatographic column 1 by temporarily opening a valve 18, a prescribed volume of the first reference gas G1' is introduced into the column 1 through a valve 14, and the first reference gas is analysed by the column 1. Next, the second reference gas G2' is introduced into the column 1, and analysed. Then a calibration curve is obtained on the basis of these analytical values. When a gas whose component are unknown should be analysed, the sample gas Gs is introduced with a carrier gas from a tank 20 into the column 1 by opening valves 9 and 19, and analysed. The obtained analytical value is corrected with the use of the preliminarily obtained errors of the standard gas from the reference gases.

IPC: H01L21/205
Filed: 1989-06-07
Abstract: PURPOSE:To reduce dislocation density when a mixed crystal epitaxial layer having different lattice constant is grown on a compound semiconductor substrate, by interrupting the growth of the mixed crystal for a while, and growing a layer of uniform composition after a gradient composition layer whose composition ratio changes is formed on a substrate. CONSTITUTION:When a epitaxial layer of mixed crystal whose lattice constant is different from substrate crystal is vapor-grown on a semiconductor single crystal substrate 5, the growth of the mixed crystal is interrupted for a while after a gradient composition layer 52 whose composition ratio gradually changes is formed on the substrate 5, and then a constant composition layer 53 is grown. That is, by the growth interruption the dislocation generated in the gradient composition layer 52 can be restrained from vanishing or propagating to the growth layer thereon. Thereby dislocation density on the surface of the mixed crystal epitaxial layer 53 of constant composition can be reduced.

Title: Refining agent for iron or steel
Inventor: TAKASHIMA TADASHI
IPC: C21C7/076
Filed: 1980-10-17
Abstract: PURPOSE: To provide both a slagmaking property and an oxidizing action in conbination and also provide an exothermic reaction by a method wherein an alkali percarbonate is incorporated as a major component in a refining agent used for desiliconization and dephosphorization.  
     CONSTITUTION: An alkali percarbonate such as potassium percarbonate or sodium percarbonate is used as a refining agent, either singly or in combination with other refining agents or a carrier, and in the form of a powder, particles or blocks prepared by mixing, molding and the like. The refining agent thus formed is added to molten iron or steel, and refining is conducted by stirring, blowing or the like. The alkali percarbonate is an unstable compound containing an excess of oxygen and capable of liberating oxygen easily to become an alkali carbonate. The oxygen thus liberated oxidizes the molten metal while converting silicon, phosphor and the like into silica, phosphor pentoxide and the like respectively, and the products of oxidation combine with the alkali carbonate to form an alkali silicate and an lakali phosphate, thereby forming fluid slag. Accordingly, the molten metal can be easily desiliconized and dephosphorized. The refining agent of this invention is suitable producing a low-phosphor steel.
