Title: Measuring method for phase-shift-interference
Inventor: NISHIKAWA NAOYUKI
IPC: G01B11/24
Filed: 1990-02-23
Abstract: PURPOSE:To perform highly accurate measurement by measuring the transmittance of a wavelength plate beforehand, and correcting the intensity of the interference fringes of refer ence light and substance light with the transmittance of the wavelength plate. CONSTITUTION:Incident laser light is converted into linearly polarized light through a polarizer 21. Then, the light passes through a wavelength plate 22. The phase difference which is determined by the characteristic of the wavelength plate 22 is imparted between the normal light and the abnormal light in the transmitted light. Thereafter, the luminous flux is split into the substance light and the reference light through a polarizing beam splitter 23. The light beams are reflected from a substance to be measured 27 and a reference light 25, respec tively, and interference frings are formed at an observing surface 29 through an analyzer 28. The wavelength plates 22, 24 and 26 are made to be to wavelength plates having the wavelengths of lambda/4, lambda/2 and 3lambda/4. The transmittance of the light of the wave length plates are made to be r1 r2 and r3. The interference fringe pattern obtained at this time is expressed by a specified expression. In order that the interference-fringe pattern is made to be the interference pattern equivalent to that when the wavelength plate having the transmittance of 1 is used, each strength of the interference fringes is divided by the transmittance of the wavelength plate used. In this way, the intensity of the interference fringes between the reference light and the substance light is corrected with the transmittance of the wave length plate.

Title: Pyroelectric sensor system
Inventor: KOJIMA HIROMASA
IPC: G01J1/42
Filed: 1985-03-07
Abstract: PURPOSE:To eliminate a latch phenomenon without any decrease in sensitivity by coupling one output terminal of a pyroelectric sensor with the output of an amplifier and coupling the other terminal with the minus input of the amplifier circuit. CONSTITUTION:One output terminal of the pyroelectric sensor 1 is coupled with the output of the amplifier circuit 2 and the other output terminal is coupled with the minus input of the amplifier circuit 2, so that the pyroelectric sensor becomes a negative feedback element. Therefore, an impedance resistance value or transient resistance value decreases greatly below a static resistance value and current amplification becomes possible, so a current flows all the time. A latch phenomenon is therefore eliminated and the need for a mechanical chopper which cuts off infrared rays intermittently is eliminated, so that the system is reduced in size and cost.

Title: Substrate for power module use
Inventor: KAWACHI TSUNEO
IPC: H01L23/15
Filed: 1992-02-28
Abstract: PURPOSE:To improve the wire bondability of aluminium wires by a method wherein the surface of a copper pattern is chemically polished to eliminate directivity in the polishing and moreover, an NiP or NiB is plated thereon. CONSTITUTION:A resist is peeled and thereafter, a copper pattern is chemically polished using a commercially available soft etching liquid. In the chemical polishing, a ceramic plate is bonded to a copper plate and, after the unnecessary parts of the ceramic plate and the copper plate are covered with the resist, the surface only of the pattern part has only to be polished. An NiP or NiB plating is applied to the surface of the copper patter subjected to chemical polishing treatment. As the NiP or NiB plating, a marketing electroless plating solution is utilized. For the thickness of the plating, a thickness of 5mum or thinner is suitable. Thereby, even aluminium wires having a large diameter can be reliably bonded and the reliability of a power module, operating at a high current, is improved significantly.

Title: Image forming device
Inventor: HOSONO NAGAO
IPC: G03B27/62
Filed: 1980-04-03
Abstract: PURPOSE:To obtain a copy in the form that part of an image is made black or blank by disposing an optical path opening-closing means that can control shutting- off of rays to an arbitrary region of the cross sectional area of an optical path and controlling the original image exposure region arbitrarily by said means. CONSTITUTION:Nichols crossed polarization filters 7, 8 are provided on the respective outer sides of two sheets of plane glasses 1, 2. 7 is used as a polarizer and 8 as an analyzer, respectively, and both 7, 8 are so disposed as to optically orthogonal or parallel each other. Voltage is applied across opposing transparent electrodes 3, 4 by a power source 9. With such constitution, the light L entering the transparent plane glass 1 from the polarizer 7 side sufficiently transmits through the transparent plane glass 2 and is held in the state of going to the analyzer 8 side while no voltage is applied across the electrodes 3, 4, but when the voltage is applied, the light transmission is shut-off. In this way, the application of light to the drum region surface is prevented during exposure by controlling the conduction of electricity, whereby the image which is made partly, for example, blank is obtained.
