Title: Heat exchanger and turbine equipment
Inventor: HASEGAWA NAOMIKI
IPC: F28F1/00
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To eliminate mixing of liquid into air thereby to prevent mixing of liquid refrigerant into cooling air that is introduced into a gas turbine. SOLUTION: In this heat exchanger, in a case where liquid refrigerant is mixed into air flowing through a heat transfer pipe group 13 of a heat exchange path 20 to flow together with the air, the air mixed with the liquid refrigerant flowing through the pipe group 13 is subjected to centrifugal force with inversion when the air mixed with the liquid refrigerant turns downward as turn flow at a lower portion of a body 11 and gravity acts on the air when flowing upward at low speed in an upward flow passage 19. By the centrifugal force, large diameter drops put on an inner wall of the body 11 and then is eliminated. While drops with low speed that cannot move upward are fallen by the gravity and are stored in a leak detecting portion 21. Liquid is eliminated from the air mixed with liquid refrigerant, so that cooling air is introduced into a gas turbine in a state where the liquid refrigerant is not mixed into the cooling air. Accordingly, the adherence of liquid on such as wings of the gas turbine and a rotor is prevented.

IPC: H01L21/768
Filed: 1979-03-23
Abstract: PURPOSE:To improve to a great extent the degree of integration of a semiconductor integrated circuit without spoiling the characteristics of a FET, by covering with aluminum the surface of a pn-junction section formed by diffusing impurity into a poly-Si gate member of C-MOSFET in the IC. CONSTITUTION:A drain layer 10 and a source layer 11 of a p channel FET are formed on an n-type Si substrate. A drain 13 and a source 14 of n channel FET are formed in a p<-> section 19. Gates 12, 15 of these FET's are formed with a continuous poly-Si layer, into which p-type impurity and n-type impurity are diffused, respectively, at the time of formation of the layers 10, 11; 13, 14 so that a pn-junction 18 occurs in an intermediate portion of the poly-Si layer. An opening 16 extending to both sides of the pn-junction 18 is made and then covered with aluminum 17 to thereby subject the gates 12, 15 to ohmic connection. Owing to this structure, the connection of the gates 12, 15 has no influence upon the operation of the FET's and causes no increase in area. This structure allows the degree of integration of an Si gate FET to be improved to a great extent.

Title: Magnetic head
Inventor: TAKASHIMA HIDEO
IPC: G11B5/105
Filed: 1984-02-27
Abstract: PURPOSE:To improve the parallel accuracy and ratio between the magnetic tape rubbing surface and a grinding reference surface of a magnetic head and therefore to improve the reliability of said head, by providing a projected part to secure a spot contact between a core holder and a case and changing the case position within a prescribed range of angles when the core holder is set to the case. CONSTITUTION:A hemispherical projected part 4d is provided at the center of a lower end face 4c of a core holder 4 to secure a spot contact with a case 6. When a head element is put into the case 6 after opening downward a plate spring 5 with pressure, a rear end face 4b of the holder 4 has a contact with a fixed face 8. Then the case 6 is pressed down in the direction shown by arrow heads. Thus the case 6 changes its position freely with the part 4d or the spring 5 defined as a fulcrum in order to control the parallel degree between sides A and B. Under such conditions, a magnetic tape rubbing surface 6a of a magnetic head is ground to keep a highly accurate parallel degree between the surface 6a and a grinding reference surface. This improves the nondefective ratio of the head and improves the reliability of the head with reduction of the cost. Furthermore the thickness of the case 6 is reduced to attain a small and lightweight structure of the head.

Title: Iron sintered parts
Inventor: MATSUMOTO SHIYUUJI
IPC: F16C33/10
Filed: 1980-03-18
Abstract: PURPOSE: To improve the lubricity of iron sintered parts and prevent the occurrence of seizure and noise by impregnating sintered bodies with lubricating liquid contg. a fine-particle solid lubricant.  
     CONSTITUTION: A powder molded article of a predetermined part shape is press- molded of iron material powder, and this molded article is sintered, whereby a sintered body is obtained. Next, lubricating liquid contg. a solid lubricant is impregnated in this sintered body. In this impregnation, the sintered body is evacuated under reduced pressure, and after the sintered body is immersed in the lubricating liquid heated under reduced pressure, it is restored to ordinary pressure, and the lubricating liquid is allowed to force-feed to the inside of the sintered both under atmospheric pressure. If the frictional surface of other part is brought into slide contact with the frictional surface of this oil impregnated type iron sintered part, the impregnated lubricating liquid is oozed out from the holes of the sintered body together with the solid lubricant, and forms an oil film between the frictional surfaces, thereby making lubricating action and preventing the occurrence of seizure and noise.

Abstract: PROBLEM TO BE SOLVED: To enable more precise measurement to a specified region of an object to be measured by calculating an inclination angle and three-dimensional position of the specified region of the object to be measured with a simple constitution. SOLUTION: A first luminous flux L1 from a first light source part 2 and a second luminous flux L2 from a second light source part 3 are reflected by a reflecting member 11 arranged on an object A to be measured.

IPC: C02F3/12
Filed: 1983-03-03
Abstract: PURPOSE:To perform treatment of waste liquid of high ammonia concn. without pretreatment or dilution by adjusting the concn. of dissolved oxygen in an aeration tank contg. waste liquid of high ammonia concn. to 0.1-0.5ppm and performing treatment with activated sludge for the adjusted waste liquid. CONSTITUTION:Ammonia liquor having 5,000ppm ammonia concn. is charged to an aeration tank and aerated to 0.3ppm dissolved oxygen. and then subjected to the treatment with activated sludge. As the result, SCN<-> is held always at <=3ppm; the superiority of the performance of the treatment is thus recognized. The control of the dissolved oxygen in the aeration tank is performed by the control of the working number of stirrers in accordance with detection signals issued by a measuring instrument for the dissolved oxygen installed in the aeration tank, or by other means. For the control of the dissolved oxygen, it is desirable to use simultaneously oxidation-reduction potential and pH as the measure for the operation. By this way, treatment of waste liquid of high ammonia concn. is possible without dilution.
