Title: Detection of origin of offset amount for sharing interference measuring system
Inventor: TSUCHIYA YOSHIYUKI
IPC: G01J9/02
Filed: 1984-01-17
Abstract: PURPOSE:To elevate the measuring accuracy by measuring phase difference between two wave surfaces at points in the interference region by a fringe scanning method each time the reference wave surface is shifted to specify the origin of the offset amount accurately. CONSTITUTION:A laser light from a laser light source 1 proceeds to a beam splitter 2 through a collimator lens L1 and the reflected component is incident into an object O to be measured through a converter lens L2. The light reflected from the object O is focused on flat mirrors M1 and M2 through a condenser L3. The light reflected on the flat mirrors M1 and M2 is incident onto a light receiving surface of an area sensor 5 through an image formation lens L4. Here, the reference wave surface is repeated several times at a specified very small interval with respect to the wave surfaces being measured. Each time the reference wave is shifted, the phase difference between the two wave surfaces at points in the interference region is measured by a fringe scanning method to specify the origin of the offset amount.

Title: Electromagnetic induction heating cooker
Inventor: KAME MASAHIRO
IPC: H05B6/12
Filed: 1994-01-25
Abstract: PURPOSE:To safely and immediately stop heating when an emergency stop is needed by immediately stopping oscillation of a switching element when a specific abnormality signal is received from an abnormality detecting device. CONSTITUTION:When an overcurrent is made to flow through either of switching elements 6a, 6b by load fluctuation, an abnormal current detecting circuit 10 detects it and outputs an abnormality detection signal to a control unit 7 to immediately lower the level of a signal to an oscillation circuit 8 to 0V, and a signal from the control unit 7 is received by the circuit 8, which then stops oscillation. Before the elements 6a, 6b are damaged by the overcurrent, the oscillation is stopped so as to prevent damage to the elements 6a, 6b. If a load temperature rises abnormalily as an empty cooker is heated, an abnormal load temperature detecting circuit 11 detects it and then outputs an abnormality detection signal to the unit 7, which then gradually lowers the level of a signal to the circuit 8. Further, the circuit 8 gradually decreases the on period of oscillating pulses, and stops oscillation when the output of the unit 7 becomes 0V.

Abstract: PURPOSE:To prevent malfunction due to a rate of rise of on-state voltage (dv/dt) by connecting a transient current detecting circuit comprising a PNP transistor (TR) having a dielectric strength voltage in both polarities whose base is opened between a 1st main terminal and a base of a TR of a variable impedance circuit. CONSTITUTION:The PNP TR 12 of transversal arrangement and having a bipolar dielectric strength charactristic is a transient current detection circuit whose input/output terminals 13, 14 are constituted by a collector and an emitter and is connected to a base of a TR 10 forming a variable impedance circuit and a 1st main terminal 6a. With a thyristor 9 not in operating state, if a rapid positive potential fluctuation is produced to the 1st main terminal 6a or a rapid negative potential fluctuation exists in a 2nd main terminal 6b, the transient current flows in a route of 6a   12, the TR 10 is driven and the current reaches the terminal 6b. In this case, the transient current is amplified by the PNP TR 12 and a larger current is obtained. As a result, the gate-cathode voltage of the thyristor 9 is clamped by the collector-emitter voltage of the TR 10 to prevent malfunction of the thyristor 9.

Title: Quench and temper of continuously cast high tensile steel material
Inventor: BETSUSHIYO KIYOSHI
IPC: C21D1/78
Filed: 1978-01-25
Abstract: PURPOSE:Continuously cast steel material is quenched from a gamma zone temperature, then requenched from a alpha+gamma zone temperature and tempered at a temperature of below A1 modification point, thus eliminating surface crack defects from the high tensile steel material. CONSTITUTION:Continously cast and rolled steel materials have segregated C, Mn, P, S, etc., produced in the casting process, at the center area of the materials. The steel material is first quanched into water from a temperature of gamma zone (austenite zone), or about 930 deg.C. The material is then maintained at a temperature of 780 deg.C which is alpha+gamma zone for about 30 minutes, to diffuse C, Mn, P, and S to the central area thereby removing temperature segregation. From this temperature the material is quenched and then tempered at about 650 deg.C which is below A1 modification point (723 deg.C) for about 30 minutes. The process thus prevents surface crack occurrence which otherwise may caused by segregated components.
