IPC: F16K17/00
Filed: 1982-07-20
Abstract: PURPOSE:To eliminate a cross-over type relief valve, by a method wherein pilot pressure chambers are formed at the opposite ends of a spool, a plunger is positioned in a manner to face the pilot pressure chamber and brought into contact with the end surface of the pressure chamber, and pump ports cross each other to communicate them with the respective pressure chambers. CONSTITUTION:A pair of first annular grooves 12 and 13 and second annular grooves 14 and 15 are formed in a spool hole 6, pump ports 2 and 3 cross each other within a valve body 1 to connect them to the first grooves 13 and 12, and actuator ports 4 and 5 are connected to the second annular grooves 14 and 15. The opposite ends of a spool 7 face pressure chambers 8 and 9, and annular recesses 34 and 35 are provided in the outer periphery of the spool. When the spool moves rightwardly or leftwardly, only one annular recess engages with the first and the second annular groove.

Abstract: PURPOSE:An extraction raw material such as animal or vegetable substance is made to contact with a supercritical gas together with an extraction assistant consisting of an alcohol or an organic solvent to effect the extraction of the extractable substance in the supercritical gas and the extractable substance is separated by varying the pressure and temperature of the supercritical gas. CONSTITUTION:The extraction raw material is mixed with the extraction assistant (e.g. alcohol, organic solvent, etc.) in the stirring tank 29, and the mixture is heated with the heat exchanger 31 and supplied to the extraction tank 27. Separately, liquid carbon dioxide is treated with the booster pump 25 and the heat-exchanger 26, and the obtained supercritical gas is introduced into the extraction tank 27 to effect the extraction of the extractable substance with the supercritical gas. The supercritical gas containing the extracted substance is introduced into the separation tank 33, and only the extracted substance is separated under a prssure 1.0-2.0 times the critical pressure at a temperature 1.0-1.2 times the critical temperature. After the separation treatment, the gas is introduced into the extraction assistant-separation tank 35. The carbon dioxide gas is circulated through the valve 36 and the extraction assistant is reused after separation the low-boiling impurities in the separation tank 37. EFFECT:The extraction assistant can be dissolved in the supercritical gas at an arbitrary ratio and an extractable substance free of extraction assistant can be produced.

Title: Manufacture of flat platelike heating element
Inventor: OMORI NOBUHIKO
IPC: H05K3/28
Filed: 1988-05-23
Abstract: PURPOSE:To enable mass producing with good workability highly reliable flat platelike heating elements resistant to a thermal shock extending over a long period of time, by spray coating and accumulating ceramic on the metal shaped into a heating electrode placed on a ceramic base and by holding and fixing said metal between both ceramics. CONSTITUTION:A tungsten foil rapped into a desired shape of heating electrode 1 is temporarily fixed on an alumina single crystal base 2 by adhesive so as to be placed on said base, alumina is accumulated and stuck through plasma spray coating to form an alumina layer 3, and said tungsten foil is held and fixed between the alumina single crystal base 2 and alumina layer 3 so that a flat platelike heating element is obtained. Accordingly, the production time of said element is as short as about one minute and the number of manufacturing processes also decreases to enable the mass production of the heating element. Further, because a tungsten foil is used as the heating electrode 1 for said flat platelike heating element, the element thus manufactured is higher in denseness and less in stress than a vapor deposited film. Therefore, said element causes neither breaking of wire nor crack and can exhibit an excellent thermal shock resistance.

Title: Magnetic recording medium
Inventor: SHIYOUBUDA FUMIO
IPC: G11B25/04
Filed: 1990-05-18
Abstract: PURPOSE:To prevent the influence of the magnetic fields at the time of writing of a magnetic head from exerting on a servo head by providing conductive layers, which have the thickness size larger than the thickness size of the skin depth thereof, on a nonconductive substrate. CONSTITUTION:Plating films or sputtered layers 12 of aluminum or copper having a film thickness h are formed on the front and rear surfaces of the nonconductive substrate 10 consisting of glass or ceramics and magnetic layers 14 are formed atop these layers. The layers 12 are the conductive layers and are formed to the thickness h at which a magnetic shielding effect is exhibited. The magnetic fields generated at the time of writing to the magnetic recording medium by the magnetic head are shielded by the conductors as the external magnetic fields are negated by the diamagnetic fields by the eddy currents generated in the conductors. The generated currents exist only in the surface layers of the thickness called the skin depth delta and, therefore, the thickness size h of the conductive layers 12 is set at the delta or above.
