Patent JP-H03285223-A (JP)
Title: Operation device
Inventor: TANAKA YOSHITAKA
IPC: H01H33/38
Filed: 1990-03-30
Abstract: PURPOSE:To reduce a load applied to a circuit-closure operation mechanism as well as to reduce in number constituent parts necessary for an operation device, by providing a superconductive magnet adapted, at the time when a switch is closed, to energize a link mechanism in the direction of closing the circuit. CONSTITUTION:When it is desired to open a VCB(Vacuum Circuit Breaker), a circuit-breakage instruction switch cs2 is closed. This results in closure of a contact Xa with its auxiliary relay X excited. This causes a superconductive coil 28c to be excited. As a result, a superconductive magnet 28 is energized. A movable core 28a is thereby attracted to rotate a cross-bar 4a counterclockwise. Thus, a movable electrode is opened. Subsequent closure of a circuit- breakage instruction switch cs1 permits formation of a self-holding circuit for an auxiliary relay Y. The resulting heat generated from a heater H makes a permanent current switch 28d open. This releases the energization of the superconductive electromagnet 28. Consequently, the holding of the opened circuit is terminated and, at the same time, the circuit-closure-breakage device is actuated to closure the VCB.

Title: Semiconductor device
Inventor: SHIMADA MASAO
IPC: H01L21/52
Filed: 1992-04-08
Abstract: PURPOSE:To lessen the peeling or cracks of a semiconductor device by equipping the uppermost layer of a metallic layer with a low melting point metallic layer for fusion, the surface of which is covered with a metallic layer for prevention of oxidation. CONSTITUTION:Ti7, Pt8, and Au9 are stuck in order to a GaAs substrate 11. Subsequently, Au 12 is stuck without being exposed to air after sticking AuSn (concentration of Sn is 20%). Since the adhesion of each layer 7, 8, 9, and 10 is performed in the same vacuum device, Ti7 and AuSn10 susceptible to oxidation are covered with Au 12 for prevention of oxidation without being exposed to air. When the concentration of Sn of AuSn10 is 20%, it is on eutectic point, and it dissolves at about 280 deg.C. Hereby, the formation of voids can be prevented, and the peeling or cracks of the semiconductor device caused by voids can be lessened.

IPC: G01N35/10
Filed: 1984-04-28
Abstract: PURPOSE:To achieve an accurate analysis by analyzing the sample in different amounts to prevent mismeasurement when the amount of the same sample exceeds the peak. CONSTITUTION:First, the amount A of a sample S in a sample cup 2 is introduced into a reaction tube T1 with a sample distributor while the amount B more than the amount A thereof (for example, ten times) into a reaction tube T2. Then, a fixed amount of a reagent is distributed into the reaction tubes T1 and T2 already holding the samples with a reagent distributor 11. Then, the reaction liquids in the respective reaction tubes T1 and T2 are separately sucked and analyzed with an analyzer 21 comprising a suction pump 22 and an analyzer body 23. Two analysis values thus obtained are checked to determine whether they coincide with the ratio between the amounts A and B of the samples. When the coincidence is given, data larger in the amount of the sample is selected or otherwise, that less in the amount of the sample is selected by a means 37. Thus, mismeasurement due to the excessive amount of the sample can be avoided to enable accurate analysis.
