Title: Diffuser of centrifugal compressor
Inventor: TAMAKI HIDEAKI
IPC: F04D29/44
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To generate no peeling at the pressure surface side of a guide vane even at the hub side having a small flow-out angle, to prevent the full pressure loss of a diffuser, and to allow to improve the efficiency. SOLUTION: In a diffuser 20, a passage space held between side walls 10H and 10S of a casing 10 is partitioned by plural guide vanes 21 provided in the peripheral direction, at the outer peripheral side of an impeller 30; the downstream from a throat forms an expansion passage in a specific expanding angle, between the guide vane 21 and the adjacent guide vane and the inner surface 20H of a hub side wall 10H, or the inner surface 20S of a shroud side wall 10S, is formed inclined, from a specific position at the downstream side from the throat to the side to reduce the passage thickness.

Title: Air-motor operated clutch
Inventor: ORII TAKESHI
IPC: F16D25/0635
Filed: 1987-04-06
Abstract: PURPOSE:To cut down the manufacturing cost of and miniaturize the captioned clutch by forming a pneumatic chamber between the inner periphery of the clutch main body and the outer periphery of a piston and introducing the compressed gas into the pneumatic chamber so that a clutch plate is pushed for contact with another clutch plate. CONSTITUTION:A pneumatic chamber 37 is formed between the outer periphery of a piston 33 and the inner periphery of a cylinder 24. When compressed gas is introduced into the pneumatic chamber 37 via an air introducing hole 38, the piston 33 moves toward the left-end side, resisting the pushing force of a spring 30. On the other hand, when the compressed gas runs out from the pneumatic chamber 37, the spring 39 puts the piston back to the initial position. Accordingly, the clutch main body, which forms the pneumatic chamber 37, does not rotate at all, thereby dispensing with a casing. Thus, the captioned clutch can be miniaturized.

Abstract: PURPOSE: To obtain economically a copolymer having excellent heat resistance, by stopping the polymerization so as to leave a small amount of unreacted monomers and introducing steam into the reaction mixture to separate the unreacted monomers, in emulsion-polymerizing an α-alkylstyrene with vinyl cyanide.  
     CONSTITUTION: A monomer mixture consisting of not less than 70wt% α-alkylstyrene represented by the formula, wherein R 1  is a 1W3C alkyl, R 2  is a 1W3C alkyl or a haloalkyl, e.g., α-methylstyrene, and not more than 30wt% vinyl cyanide is emulsion-polymerized by using a radical initiator, e.g., potassium persulfate. The polymerization reaction is stopped when the content of unreacted vinyl cyanide becomes 3wt% or lower, based on the total monomers. Then, title high α-alkylstyrene content copolymer is obtained advantageously by introducing steam into the resulting copolymer latex thereby to separate and recover the unreacted monomers remaining in the copolymer latex.

IPC: G06F12/00
Filed: 1986-04-09
Abstract: PURPOSE:To prevent a partial overflow from arising an a data file by providing a file controlling a data storage place and a file storing information retrieving data. CONSTITUTION:The data file 4 is composed of plural areas (extents), and the control file 5 controls to which extent and the it which position on record is stored.

Abstract: PURPOSE: To make attachment strong by removing mini impurities attached with metal ions collided into the surface and then by attaching an attached metal when attaching an electrode with a vapor deposit in the surface of a piezo-electric element.  
     CONSTITUTION: An piezo electric element is fixed below a deposit dome 7 and sealed by a deposit velgier 8 whose inside is at a vacuum of 10 -1 ∼10 -3  Torr. Then about 1KV of high voltage is built up to a W-type ring 9 set up in the velgier 8 and ions jumped from the surface of a ring 9 or fine impurities sticked to the surface of an element 6 are removed. And a high voltage is shut off after 5 to 10 minutes and a vacuum rate in the velgier 8 below 5×10 -5  Torr. Vapor-deposited metals such as Cr and Au or Cr and Ag from a vapor source 10 are sticked to the surface of the element 6. Thus, stickness becomes stronger to stabilize a filtering feature when used for piezo-electric porcelain and filter.

Title: Ultrasonic cutter device
Inventor: TERADA SOTARO
IPC: B26F3/00
Filed: 1994-03-30
Abstract: PURPOSE:To decrease the accidents of damaging a tool hone in particular so as to reduce the fray etc., of a cutting plane and to enhance the durability of a device as a whole by forming the corner of the end of the tool hone into an acute-angled cross section. CONSTITUTION:The vibration of a tool hone 7 is applied on a machining-blade support surface 31A along its support shaft and in a predetermined direction a of inclination. An ultrasonic vibration component that contributes to cutting is therefore only that which is oriented perpendicular to the machining blade support surface 31A. An ultrasonic vibration component that does not contribute to cutting works perpendicular to the direction of cutting. Therefore, the component perpendicular to the direction of cutting by the ultrasonic vibration works in a direction for separating one cut planar member M from the other planar member M. When the corner of the tool hone 7 is set to an acute angle, the device cuts well with each motion, enabling the speed of operations to be increased. The acute-angled corner can reduce fray etc.
