Title: High-sensitivity interferometer
Inventor: KANOU HITOSHI
IPC: G01D5/26
Filed: 1983-11-07
Abstract: PURPOSE:To reduce output variation greatly and to improve resolution, precision, and stability by switching one light beam from an optical branching device so as to make incident to an optical fiber for measurement or optical fiber for calibration through an optical switch. CONSTITUTION:The output of interference between light passed through the optical fiber 5 for measurement and light passed through an optical fiber 4 for reference is calibrated with the output of interference between light passed through the optical fiber 6 for calibration and the light passed through the optical fiber 4 for reference. Consequently, a stable, drift-free output is obtained, so the output variation is reduced greatly and the resolution, precision, and stability are improved. Further, even if there is a factor of drift generation, the drift is reduced, so a countermeasure (e.g. temperature control in case of pressure measurement) to the drift factor is unnecessary, thereby simplifying the whole constitution.

Abstract: PURPOSE:To enable simultaneous data writing on the entire surface, enable a written condition to be maintained for a long time and enable a larger area and a higher density, by a construction wherein a memory medium returned from a second optical characteristic to a first optical characteristic when a bias is applied thereto is clamped by a plurality of electrodes. CONSTITUTION:A superlattice film 3 is provided by carrying out an RF glow discharge decomposition method, a sputtering method, a photo-CVD method or the like using, for example, a mixed gas of SiH4 and B2H6 for a p-layer and similarly using, for example, a mixed gas of SiH4 and PH3 for an n-layer. This process is repeated to periodically providing pnpn...pnp layers so that the thickness of each p-layer and that of each n-layer are substantially equal, thereby obtaining the superlattice film. Writing is conducted by setting the device in a short-circuit condition, and irradiating the device with rays, preferably having a frequency selected in the range from IR rays to UV rays. Though writing may be conducted with a bias applied to the device, the ratio of change in optical characteristic is maximized when the bias is 0. When optical writing is carried out with a bias of 0, the ratio of change in the optical characteristic reaches its maximum.

Title: Lead terminal for electronic component
Inventor: YAGYU KOICHI
IPC: H05K3/34
Filed: 1987-08-25
Abstract: PURPOSE:To easily restore a shape even when lead terminals have come close to each other or have been deformed by a method wherein the lead terminals extracted from a component element are constituted by a shape memory alloy. CONSTITUTION:Lead terminals 4 composed of a shape memory alloy are used; a material to be used is an alloy which is subjected to a thermoelastic martensitic transformation; the temperature hysteresis between a transformation starting temperature and a reverse-transformation starting temperature is less than about 30 deg.C. A martensite caused due to a temperature drop or a temperature rise is grown or contracted continuously; its matching performance is kept at a boundary between a mother phase and a martensite phase. The reverse-transformation starting temperature is set at about 200 deg.C where a solder is melted; a soldering operation can be executed in a short time without a loss to bend the lead terminals again or the like. The lead terminals whose shape has been restored due to a heating operation by the solder or the like completely eliminates a residual strain at the boundary between the mother phase and the martensite and inside the martensite due to the heating operation at a temperature of higher than the reverse-transformation starting temperature; they are transformed reversely to the mother phase of a stable crystal structure; accordingly, a sufficient bonding operation which complies with a purpose to connect a component element 1 to a printed-circuit board 3 is realized.

Abstract: PURPOSE:To realize a simpler, higher-precision method of rating for a semiconductor wafer by a method wherein the reflection ranging wide in intensity of a wafer surface is digitized and the resultant numbers are used to standardize the degree of the light transmitting feature of the wafer. CONSTITUTION:A white light from a light source 1 is converted into a monochromatic light in a spectroscope 2 and then penetrates a GaAs specimen 3 after passing through a gap provided in a detector 4 measuring the light reflected from the surface of the specimen 3. The light is then detected by the detector 5 after penetrating the specimen 3. The detector 5 sends out signals that are supplied to a recorder 7 and digital voltmeter 8 after passing through an amplifier 6. Reflection from the specimen 3 detected by the detector 4 is supplied to a digital voltmeter 9 and used to standardize the light displayed by the digital voltmeter 8 after passing through the specimen 3. Real-time rating of the specimen 3 is possible when a data processing system 10 with a display is provided. A system using an optical band-pass filter instead of the spectroscope 2 is also acceptable and is lower in price.
