IPC: H01F41/02
Filed: 1987-04-17
Abstract: PURPOSE:To increase the space factor of iron cores, by contracting the step parts of each part of the iron core, in the manufacturing method of the picture-frame shaped iron cores having leg parts iron cores, the iron cores and yoke parts, whose cross sectional shape is a circular, semi-circular or elliptical shape. CONSTITUTION:Electromagnetic steel-plate groups 100A and 100B are arranged in a symmetrical pattern with respect to a central line, which is in parallel with a laminating surface of a circle with a radius R. The steel-plate groups 100A and 100B are constituted with the laminated bodies of many sheets of electromagnetic steel plates 10x1-10xn each having a thickness (t), with arranging spaces for compressing members 5 being made to remain. Each electromagnetic steel plate is cut in a specified size, e.g., a width Cx, so that both edges of each electromagnetic steel plate conform to a circumscribed circle having a radius R. When compressing force is applied on the surfaces of the laminated layers with a binding tape layer 6 and a unitary body is formed, only slight gaps, which are determined with the thickness (t) of each electromagnetic steel plate, is made to remain at the step parts on both sides of each electromagnetic steel plate. Therefore, the space factor is high in comparison with that in a conventional iron core, and the picture-frame shaped laminated iron cores having the small cross sectional size is obtained.

Title: Heat pipe type solar heat water heater
Inventor: IWAMURA KAZUYUKI
IPC: F24S10/95
Filed: 1982-06-02
Abstract: PURPOSE:To improve the heat exchange efficiency of the heat pipe with respect to water in a hot water storage tank by a method wherein the hot water storage tank of a large capacity is divided into a plurality of sub-tanks of small capacity so that the heat exchange between a condensing section of the heat pipe and the water is performed within the sub-tanks. CONSTITUTION:The sunlight passed through a glass body 10 boils an operating liquid at an evaporation section 3a within the heat pipe 3. In this case, the latent heat of evaporation of the operating liquid is adsorbed at the evaporation section 3a and is discharged at the condensing section 3b to thereby heat the water 5 in the sub-tanks 11. Thus, when the water 5 in the sub-tanks is heated to a high temperature, the specific gravity of the water becomes small so that the water flows into the hot water storage tank 2 from a forward pipe 13 and an inlet port 15 through a hose 17 due to a convection phenomenon. At the same time, the low temperature hot water in the tank 2 passes through a hose 18 from an outlet port 6 and flows into the sub-tanks 11 from a return port 14.

Abstract: PURPOSE: To easily and efficiently obtain a pellicle film by controlling the temp. of a substrate to be slightly higher than the dew point when a pellicle film formed on the substrate is peeled from the substrate surface. CONSTITUTION: The material for formation of a pellicle film is dissolved in a solvent to prepare a soln. of 3-10% concn. The obtd. soln. is applied to form a pellicle film on a silicon substrate or glass substrate by soln. casting method using a spin coating or knife coating device. And, when the pellicle film is peeled from the substrate to obtain a pellicle film, the temp. of the substrate is controlled to be a slightly higher than the dew point and the film is peeled from the substrate. For example, when the film is formed in a clean room at 23 deg.C and 50% relative humidity, a cooling plate is maintained at 11 deg.C, which is slightly higher than the dew point 10.8 deg.C under those conditions. Then, the substrate is mounted on the cooling plate and cooled to peel the pellicle film from the substrate.  Thereby, only the substrate surface necessary for peeling can be selectively exposed to a water vapor environment and the film can be easily peeled.
