Patent JP-S569604-A (JP)
Title: Pipe turbine
Inventor: MURAOKA TADAO
IPC: F01D1/00
Filed: 1979-07-02
Abstract: PURPOSE: To increase the thermal efficiency of a pipe turbine and minimize its fuel consumption by forming a portion of a circular-shaped air duct into a wave-shaped configurations to provide proper rotation speeds for the turbine and by installing a wave-shaped swirling air duct in a pipe compressor.  
     CONSTITUTION: Fuel gas is alternately fed into combustion chambers 8 and 8' when used as a gas turbine. Combustion gas and compressed air are alternately ejected from nozzles 9 and 9' through a circular-shaped air duct a portion of which is modified into a wave-shaped air duct so that compressibility may be obtained. The compressibility thus obtained produces a suitable rotation power which serves as a power source. The compressed air recovers heat by cooling the superheated air duct. High speed gas from the nozzle 9 proceeds along expansion plates 4, 5 and 6 where the gas is fully expanded and discharged from a hollow part 14 of a rotation shaft into a flue 15. In a wave-shaped pipe compressor 16, air enters from a hollow part 17 of the shaft and is compressed by a centrifugal action produced by a wave-shaped spiral air duct which is thick in radius directions. The device serves to increase the thermal efficiency and minimize the fuel consumption of a steam turbine, gas turbine and wave-shaped pipe compressor.

Title: Pneumatic tire for automobile
Inventor: HATADA YUJI
IPC: B60C11/03
Filed: 1993-04-12
Abstract: PURPOSE:To secure noise performance by arranging one pitch length in the circumferential direction of blocks in the state of being changed randomly, and changing the groove width of lateral grooves within a specific range. CONSTITUTION:In the tread pattern, one pitch length L1, L2, L3 in the circumferential direction of side blocks 19 and shoulder blocks 20 is arranged being changed randomly in three kinds in this example, and the groove width Gx of lateral grooves is changed within a range of Gx=0.8G-1.2G, where G in the groove width Gx is the groove width in relation to the basic pitch length of the blocks. In the case of being 1.2G or more, the lateral groove width becomes too wide, so that maneuvering stability is lowered. In the case of being 0.8G or less, the lateral groove width becomes too narrow, so that wet performance is lowered. A silencing system of dispersing mutual noise frequency into white noise is formed by the setting of Gx=0.8G-1.2G.

Abstract: PURPOSE:To form an approximately circular hole everywhere on a black matrix film for filling each phosphor dot, including the peripheral part of the phosphor screen by superimposing an arc length direction in a reversal point of switch turn movement of a light source, on the longitudinal direction of the phosphor screen. CONSTITUTION:As a light source 2, an extra-high pressure mercury lamp is arranged in a pipe manufactured out of opaque material provided with an opening. A long arc light source is coated with a cover provided with a slit for extracting irradiation light, notched perpendicular in the arc length direction, and is thus used. The mercury lamp is fixed perpendicular to shafts running the enter of the slit and running the center of a phosphor screen 1, and switch turn movement is repeated around the shafts, i.e., after the lamp is rotated by a certain angle, it is then rotated in reverse by the same angle. The arc length direction of the light source 2 in a switch turn position is superimposed on the longitudinal direction of the phosphor screen 1. The hole shape of a black matrix and a phosphor dot shape are thus closer to the circular shape.

Title: Roll stand with roll movable in axial direction
Inventor: YURUGEN ZAIDERU
IPC: B21B13/14
Filed: 1988-04-08
Abstract: PURPOSE: To prevent a product steel strip from warping, and to uniformalize its thickness by forming a projecting and recessed profile alternately on a roll body, and setting the profile which the gradient of a surface ridgeline in the change position of a cross-section becomes a maximum. CONSTITUTION: For the profiles of the rolls 20, 21, by setting a roll radius (r) and the position (x) in the axial direction as a polynomial expression of the fifth degree, and by substituting the fixed value of the roll for the polynomial expression of the fifth degree, the profiles of the rolls are determined. At this time, it is set so that the profile of the roll 20 on the one side corresponds as the image of the profile of the roll 21 on another side, and in the positions where the cross-sections of the rolls are changed, the gradients of the surface ridgelines of the rolls are formed as maximum values respectively. Consequently, the most parts of the bending of the rolls are performed in parabola shapes. And, since the surface ridgelines of the rolls have the maximum values, the most parts of the bending of the rolls 20, 21 are compensated.  Therefore, the rolled product steel strip is prevented from warping, and the thickness is uniformalized.

Title: Recording head, recording device and recording
Inventor: NEMOTO KAZUHIKO
IPC: B41M5/382
Filed: 1994-03-31
Abstract: PURPOSE:To make it possible to detect the intensity of a heating beam such as laser beam with a concurrent action to maintain the output utilization efficiency of the heating beam at high level, and enhance detection accuracy by introducing a beam intensity detection means through an area between a heating beam emission means and a recording material storage part during the non- heating time of a recording material. CONSTITUTION:If data is optically recorded, i.e., if a dye 22 is not heated by a laser beam, a light-receiving element 79 is inserted into an area between a laser 18 and a dye storage part 37 and the laser beam L having the same output intensity as an emitted laser beam L during recording is emitted directly into the light-receiving element 79 for front monitoring. A printer head 40 can use an output of the laser beam L required for the gasification of the dye on a recording sheet to a maximum extent without wasting the output. This is because the light-receiving element 79 is introduced into the proceeding direction of the emitted laser beam L only when the output is monitored, and the light- receiving element 79 is restored to an original position when recording data.

Abstract: PURPOSE:To enhance the reliability of a printed wiring board by a method wherein, during a heat treatment for fixing a catalyst nucleus, an oxide film formed around the catalyst nucleus is removed surely without dropping the catalyst nucleus from an adhesive layer and the adhesion property of a plated layer with the adhesive layer is enhanced. CONSTITUTION:A catalyst nucleus is given to a roughened adhesive layer which has been formed on a board; then, a plated resist is formed; after that, an electroless plating operation is executed; a conductor circuit is formed. After the catalyst nucleus has been given and before the electroless plating operation is executed, the board is heat-treated in order to fix the catalyst nucleus. During the heat treatment, an oxide film which has been formed around the catalyst nucleus is removed and, after that, an electroless plating operation is executed. In order to remove the oxide film, the board is immersed in a solution which contains a reducing agent. Only oxygen which has formed the oxide film is removed. Consequently, the catalyst nucleus is not dissolved and dropped from the board as different from a case where it is removed by means of an acid.
