Abstract: PURPOSE:To quickly execute measurement with the aid of simple constitution by adjusting light flux on a prescribed optical path with the aid of a shape memory alloy part which is deformed by the change of a temperature caused by the irradiation of the light flux. CONSTITUTION:The shape memory alloy part 5 is arranged between a condensing mirror 3 and a slit 4 and it consists of a set of blocks 51A and 51B and a set of shape memory alloys 52A and 52B. The tip part of a rod 33 on the mirror 3 side is sandwiched by the tip parts of the alloys 52A and 52B and the shapes of thereof are stored so that the alloys 52A and 52B are curved in the directions of the other alloys 52B and 52A as the temperature gets high. When the light flux 7 radiated from the recessed surface 31 of the mirror 3 runs off the prescribed optical path, the block 51A is irradiated by the light flux 7, for example, the block 51A generates heat by absorbing the energy of the light flux 7 and the alloy 52A has the high temperature caused by the heat and it is deformed toward the alloy 52B. Thus, the rod 33 is turned in a direction shown by an arrow X and the mirror 3 is also turned. As the result, the optical path of the light flux 7 is corrected so that the light flux 7 is passed through a passing hole 41.

Title: Image memory
Inventor: KOBAYASHI KATSUTARO
IPC: G06T1/60
Filed: 1991-04-16
Abstract: PURPOSE:To reduce the occupancy area of a data register and to restrain the increase of a chip size by making plural sense amplifiers correspondent to the data register, selecting an sense amplifier and connecting it with the data register. CONSTITUTION:Data amplified by sense amplifiers 15(SA 1 to SA 8) are sent to read data registers 2(RDR a to RDR d) via a transfer gate TG opened and closed by transfer signals DT 1 and DT 2 and latched. These signals DT 1 and DT 2 are controlled so as to open the TG for a specified time for transferring data after the sense amplifiers 15 are amplified and thus, two sense amplifiers 15 are selected for a one bit read data register 2 and data is transferred. Since the number of data registers is reduced by this constitution, the occupancy area is reduced and the increase of the chip size is restrained. The constitution of a write register is almost similar to that of the read register 2 as well.

Title: Identifying system
Inventor: SUZUKI YASUO
IPC: G01S13/82
Filed: 1993-03-17
Abstract: PURPOSE:To allow highly accurate identification of resonance circuit by providing means for identifying resonance based on the level characteristics and phase characteristics of a reflection wave from a resonance circuit. CONSTITUTION:A transmitting means 102 transmits a continuous radio wave having frequency of predetermined range to a resonance circuit sheet 1. The wave reflected on the sheet 1 is received by a receiving means 110 which inputs a receiving signal to an identifying means 129. The identifying means 129 makes a judgement whether the level characteristics and phase characteristics of the reflected wave correspond to those prevailing at the time of AC parallel resonance or not. If they correspond each other, the means 129 decides that a circuit resonant at that frequency is present on the sheet 1. The decision is made sequentially for the predetermined range of frequency. The sheet 1 is set to function as an inherent label through combination of two arbitrary resonance circuits among ten resonance circuits. This constitution allows identification of any label.

Title: Pulse generating circuit and phase comparing circuit utilizing pulse generating circuit
Inventor: WADA KENZOU
IPC: H03K5/26
Filed: 1983-05-14
Abstract: PURPOSE:To eliminate the loss of a pulse and prevent resonance in a desired band by applying a reference input signal to both terminals of a capacitor connected to a step recovery diode in parallel, and generating a pulse wave which contains higher harmonic wave of the reference input signal at both terminals of said diode. CONSTITUTION:A pulse generated by the step recovery diode X1 is reflected completely through the short-circuit effect by a capacitor C and does propagate to a transformer T1. Therefore, the loss of the generated pulse is improved. Resonance by an input circuit, on the other hand, becomes the serial resonance of an equivalent circuit consisting of a capacitor C1, electric length (l), and opposite-directional capacitance Cd of a diode X1 as shown in figure because of the presence of the capacitor, so that the influence of the input circuit upon before the capacitor C1 is ignored. For the purpose, the electric length (l) is selected to put a resonance point outside of the desired band. A phase comparing circuit which utilizes this circuit as shown in figure samples a microwave input by a higher harmonic wave generated by the diode X1 to obtain a beat wave output corresponding to the phase difference between the reference wave and microwave.

Filed: 1996-04-05
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor tester, which can maintain an electric contact state under the high-temperature environment of a wafer burn-in test excellently and a probe unit for the tester. SOLUTION: A probe unit 10 is formed in correspondence with each semiconductor chip 8 of a semiconductor wafer 2. The units are combined, and a probe plate 11 is constituted. The wafer 2 is contained in a wafer holder 1. The probe plate 11 is applied and the wafer is pushed by a pouching unit 15. For the holder 1, material having the thermal expansion coefficient close to that of the wafer is used. A bump 20, which is the contact piece of the probe unit 10 corresponding as a chip unit, is contact with the electrode pad of each chip 8. Thus, the amount of the position deviation at every probe unit 10 becomes about several μm when exposed to the high temperature of about 125 deg.C. Therefore, the amount of the maximum position deviation can be made less than 1/10 comparison with the entire wafer, and the replacement of the probe unit 10 is simplified.

IPC: H01L21/027
Filed: 1989-03-31
Abstract: PURPOSE:To generate a rectangle beam and a forming beam other than the rectangle beam, and make it easy to correct the position deviation of said forming beam from the rectangle beam, by deflecting a first forming aperture image on a second forming aperture in the manner in which one fixed point and two fixed sides sandwiching the point between them are formed on a sample surface. CONSTITUTION:Between a first and a second forming apertures 41, 42, a forming deflection system 24 for beam forming is arranged; sizes and shapes of charged beams of rectangle and of the other forms are controlled, thereby drawing a desired pattern on a sample 11. In this charged beam pattern drawing method, when the first aperture image 41a is deflected by the forming deflection system 24, the beam other than the rectangle beam is generated, and the size is controlled, the first forming aperture image 41a is so deflected on the second forming aperture image 42 that a fixed point 61 and two fixed sides 62 putting the point 61 between them are formed on a sample 11 surface. For example, when the beam other than the rectangle beam is formed, the position deviation with respect to the rectangle beam generates on the sample 11 surface, which deviation is corrected by scanning deflection systems 25, 26 used as a positioning means on the sample 11 surface.
