Title: Cover coating composition for printed wiring board
Inventor: NITTA KATSUNORI
IPC: C08L63/00
Filed: 1987-12-03
Abstract: PURPOSE:To obtain the title resin composition improved in soldering heat resistance and bending resistance, by adding an epoxy resin to a system containing a polyamino-bismaleimide prepolymer and a catboxylated phenol resin. CONSTITUTION:The title composition is prepared by adding an epoxy resin (preferably, a novolac epoxy resin) to a system containing a polyaminobismaleimide prepolymer and a carboxylated phenol resin (e.g., acryl- modified phenol resin). When the above three resins are dissolved in a common solvent, a reaction of bonding them together takes place to form a new polyimide-modified resin, and when this resin is applied as a cover coat to a flexible printed wiring board and cured, a film excellent in bending resistance and soldering heat resistance can be formed.

IPC: G01B11/06
Filed: 1994-12-08
Abstract: PURPOSE: To precisely estimate thickness of two adjacent thin film layers in multiple lamination layer films with unknown thicknesses by assuming that one of the layers has a substantially uniform thickness. CONSTITUTION: A reference library of reflectance us. wavelength characteristic is generated in a wide thickness range of a film in the first layer 40 of lamination layers.

Experimental data of the reflectance us. wavelength are obtained from multiple points in the lamination layer, and respective discriminating characteristics are matched with those of the library. Then, the least square errors between the respective stored values in the library and the measured discriminating characteristics are generated, and the mean least square error is computed from those for which the discriminating characteristics closest to those of the library.  After generation of a new library and mean least square error computing is repeated and the minimum value is found, the optimum library represents the estimation value closest to the thickness of the second layer 42, and the estimation value optimally matching with the experimental discriminating characteristic shows the thickness of the first layer 40.

Title: Resistor and variable resistor for high electric power
Inventor: TANABE KOJI
IPC: H01C7/00
Filed: 1989-11-24
Abstract: PURPOSE:To increase applied power per unit area as a resistor which can withstand the use at high electric power by forming a spot shaped noble metal part on the surface of a resistor part. CONSTITUTION:At least one kind of a noble metal part comprising gold, silver, platinum, rhodium or alloy containing these metals or the like is formed in a spot shape on the surface of a resistor part. It is preferable that the particle diameter of the powder of the noble metal part is set at 0.3-20mum and the noble metal part and the surface of the resistor part are sintered at the contact point. In a variable resistor, the surface of the resistor part of the resistor body is electrically in contact with a metal brush through the particles of the noble metal part which are present in the spot shape. Since the metal brush which is slidden on the surface of the resistor part is in direct contact with the noble metal part, the contact resistance can be made low. Even if high electric power is applied, the contact part is not heated, and the very reliable device is obtained. Since the noble metal part is not the constituent component in a resistance applied film, basically there is no effect on the resistance value of the resistor part. The dispersion of the resistance value is not increased.
