IPC: F25B47/02
Filed: 1983-06-15
Abstract: PURPOSE:To permit to take out any amount of heat from a hot-water reserving tank upon the rise-up of heating or defrosting and prevent mixing of hot-water with water by a method wherein the flow of water is reversed in case the heat is taken out of the hot-water reserving tank or the same is taken into the tank. CONSTITUTION:One end of the water side connecting port of a refrigerant to water heat exchanger 11, provided at the outside of the hot-water reserving tank 10, is connected to the upper part of the tank 10 and the other end thereof is connected to the lower part of the tank 10 while a reversible circulating pump 15 is provided on the way to constitute a water circulating path. The flow of water is reversed when the heat is taken out of the tank 10 and the heat is taken into the tank 10. According to this method, upon the rise-up of heating or defrosting, the water is circulated into the reverse direction of the flow upon heating the supplying hot-water while the hot-water of medium temperature is taken out of the middle section of the tank 10 and cold water is returned to the bottom part of the tank 10, therefore, any amount of heat may be utilized and the hot-water will never be mixed with the cold water. Many valves or complexed pipelines are not necessitated and, therefore, the cost of the system may be reduced and the reliability thereof may be improved.

Filed: 1984-05-25
Abstract: PURPOSE:To simplify a method of detection, by supplying diluted ammonia water to a cooling water system and mixing fuel with high-concentration sulphur containing substance and operating an engine for the specified length of time and measuring gas leakage volume from sulphur content concentration measured by extracting diluted ammonium water. CONSTITUTION:Diluted ammonium water is used as cooling water and high-content sulphur mixed gasoline as fuel, and when on engine 1 is started with cooling water supply apparatus 2 and fuel supply apparatus 3, the contained sulphur is brought to combustion into oxides of sulphur and combustion gas leaks from a joining surface of cylinder block and head and mixes with cooling water for ionization to solphur ions. Further, cooling water is taken out for sampling from a sampling valve 2b, such cations as ammonia, etc. are removed by preliminary processes and sulphur ions as anions are taken out for a quantitative analysis. By these procedures, it was found that the operating time is approximately proportional to the sulphur content, i.e. leakage volumn of gas and sealing condition during operation can be evaluated.

Title: Floating type magnetic head slider
Inventor: ITO MASARU
IPC: G11B21/21
Filed: 1989-04-28
Abstract: PURPOSE:To realize low floating by providing a recessed part on the floating surface. CONSTITUTION:When a magnetic disk medium 20 starts to rotate, air flows in between the medium 20 and a floating type magnetic head slider 10. Air flows from a tapered part 11 to the direction of a trailing edge 13, and floating force works on the slider 10. In recessed parts 14, 15, force (negative pressure) for pressing the slider 10 against the medium 20 works. When the medium 20 becomes some rotating speed, pressing force of a supporting spring, floating force and negative pressure are balanced, and the floating quantity of the slider 10 becomes constant. Because of the negative pressure, the floating quantity of the slider 10 becomes smaller than before, therefore, low floating is realized. Also, in the course of floating of the slider 10, negative pressure is generated in the recessed part 14, 15, therefore, rigidity of an air film becomes high in a corner part of four corners. Accordingly, floating of the slider 10 in the rolling direction and the pitching direction becomes more stable than before.

Abstract: PURPOSE:To obtain a table picture independently of temperature by providing a means eliminating bimetal phenomenon between a transformer at the stator side and a lower drum so as to eliminate the effect of deformation with the contact of the stationary transformer. CONSTITUTION:The lower part of a bush 10 is tapered to be contacted and fixed with the inner circumferential edge of the stationary transformer 7 and to make mutual alignment between the transformer 7 and a lower drum 8. In this case, the inner diameter of the transformer 7 is selected smaller than the inner diameter of a rotary transformer 4, the bush 10 fixes the stationary transformer 7 and is not contacted with the rotary transformer 4, then smooth rotation is attained. In fixing the stationary transformer 7 onto the lower drum 8 in a rotary magnetic head device, since they are not stuck entirely, even when temperature changes and there is a difference of expansion between the stationary transformer 7 and the lower drum 8, they give no stress to each other and no bimetal phenomenon takes place. Thus, comparatively stable constitution is attained against temperature change.
