Title: Semiconductor device
Inventor: KATAYAMA YOSHIFUMI
IPC: H01L29/786
Filed: 1981-03-30
Abstract: PURPOSE: To improve a character while reducing an influence by a particle boundary area by permitting the vicinity of the particle boundary area of polycrystal silicon film to contain the elements of hydrogen, fluorine chlorine and others.  
     CONSTITUTION: At least one element selected from the group including hydrogen, fluorine, chlorine, boron, idodine, lithium, natrium, kalium, rubidium and cesium is caused to be contained in the vicinity of particle boundary of polycrystal silicon film. It may be considered effective that the quantity of the contained monad is 100ppm in valence ratio substantially when the particle size of the crystal is measured large and the proportion of the particle field to the total volumn is relatively small. If the particle size of the crystal is reduced into amorphous condition, it becomes 40% substantially in valence ratio. The containing method wherein the polycrystal semiconductor film is processed with a heat treatment in the plasma atomosphere of the element, is considered more effective.

Title: Treatment of planographic printing material
Inventor: TAKAGI YOSHIHIRO
IPC: G03C8/32
Filed: 1993-02-10
Abstract: PURPOSE:To improve printing performance such as resolution and printing durability by using two baths for development, preparing a first bath containing a developer which does not substantially cause diffusion transfer development, and preparing a second bath containing a silver halide solvent which is necessary to causes diffusion transfer development. CONSTITUTION:This planographic printing material is developed by using two baths. The first bath contains a developer which does not substantially cause diffusion transfer development, while the second bath contains a developer containing a silver halide solvent which is necessary to cause diffusion transfer development. Namely, the developer in the first bath is a developer for reversal development, in which dissolving property can be suppressed by controlling the kind and quantity of the silver halide solvent. This developer 18 substantially a developer which contains no silver solvent. On the other hand, the developer in the second bath is such a developer for dissolution transfer development with high dissolving property. Thus, the silver halide which is not developed is further transferred to physical developing nuclei and precipitated as a silver image. By using two-bath development, reversal development and dissolution physical development are separated so that enough resolution and printing durability are obtd.

IPC: H01Q3/38
Filed: 1990-02-27
Abstract: PURPOSE:To eliminate undesired fluctuation of beam directivity by applying filtering processing to a phase of each element to be measured, eliminating an error component due to the measurement and decreasing the interval of correction. CONSTITUTION:An element to be measured is rotated every 90 deg. to measure voltages V1-V4 shown in the Figure and a CPU 11 fetches the result. It is substituted in equation to calculate a relative phase difference phik with respect to a reference vector. The phase difference phik is stored in a prescribed address of a filtering processing memory area M. The filtering processing is implemented by using the value. The measurement by an integral monitor is implemented at the end of scanning and the phase is rotated by four states to one element. The cut-off frequency of the filtering referred to as omega0 is selected so that an error component fluctuated at each measurement of the transmission rate is eliminated and only the drift component changing little by little due to temperature fluctuation is extracted.

Title: Heat exchanger
Inventor: OOHARA TOSHIO
IPC: F28F1/30
Filed: 1983-03-21
Abstract: PURPOSE:To provide a thin-walled, light weight heat exchanger by brazing a corrugated material thinner than a certain thickness onto a meandering tube having a brazing material coated or adhered on it. CONSTITUTION:A fin 6 having a wall thickness less than 110mum and a width more than 15mum is held in position by a welding jig in such a manner that it is interposed between a tube 3 which is wound to meander, and such is brought into an oven to vacuum-heat to melt a brazing material on the surface of the tube 3, which completes the brazing between the tube 3 and the fin 6. As the fin 6 has only a core material 1 and does not contain the brazing material 2, silicon 1a in the brazing material does not diffuse into the core material 1 even after brazing. Although there may be a case where a trace silicon may diffuse into parts where a part of the fin 6 is joined with the tube 3, such parts have adequate stiffness and are able to bear the necessary brazing load as they are solidly welded to the tube 3.
