Inventor: KAARU NIISE
IPC: A47J27/08
Filed: 1993-11-25
Abstract: PURPOSE: To provide a steam pressure cooker easy-to-use and stable in performance without any danger of penetrating a water into the inside along a dome.

Title: Exhaust passage structure of engine
Inventor: TANAKA TAKAYUKI
IPC: F01N13/10
Filed: 1987-11-24
Abstract: PURPOSE:To prevent the deformation without losing the light weight by disposing branch exhaust passages cosisting of steel pipe respectively collecting at one side end in the cylinder lineup direction of an engine, and forming the branch exhaust passage positioned at the collecting side in a relatively large thickness. CONSTITUTION:At exhaust ports #1 to #4 of a multicylinder engine E, branch exhaust passages 5 to 8 which consist of steel pipe respectively are connected. In this case, in order to avoid the interference with an auxiliary machinery 11, the branch exhaust passages 5 to 8 are bent and extended pointing to the obliquely rear side, at the rear of the cylinder lineup direction, and then connected to single common exhaust passage 13 at the exhaust collecting part 12. And since the fourth branch exhaust passage 8 is liable to generate a deformation in the bending process, its thickness is set larger. On the other hand, the first to the third branch exhaust passages 5 to 7 are not liable to generate the deformation, their thickness is made smaller. In such a composition, the deformation can be prevented without losing the lightweight effect of the steel pipes.

Title: Fluorescent character display tube
Inventor: KOBAYASHI KOJI
IPC: H01J29/08
Filed: 1986-12-11
Abstract: PURPOSE:To reduce the phosphor blot-like luminescence fraction defective by making the content of the alkaline metal oxide contained in a conductive layer 1.0-3.0 wt.%. CONSTITUTION:A fluorescent character display tube has a conductive layer 7 using graphite as a main component and a phosphor layer 8 provided on the conductive layer 7, and the content of the alkaline metal oxide contained in the conductive layer 7 is made 1.0-3.0 wt.%. If the quantity of the alkaline metal oxide is reduced to 1.0-3.0 wt.%, the decomposition of the phosphor is reduced by the diffusion of water glass into the phosphor layer and the reaction between the water glass and the phosphor progressing in processes after the phosphor layer forming process while the strength of the conductive layer 7 itself and the binding strength with its bed layer are secured. Accordingly, the brightness of the fluorescent character display tube is remarkably improved, and the phosphor blot-like luminescence fraction defective due to the local decomposition of the phosphor is sharply reduced.

Title: Fixing method of half-split sleeve for bearing
Inventor: KAWAMURA SUNAO
IPC: F16C35/02
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent an excessive local load generated in a fixing part, and to slide a shaft or a bearing in the shaft direction by fitting a cylinder smaller than a sleeve outside diameter in an end part of a half-split sleeve worked in a step shape. SOLUTION: A sleeve 2 is arranged in a stepped part 1a of a shaft 1 on the shaft side of a bearing 5 for the purpose of protecting the shaft 1, and is split into two halves so as to be easily mounted on and demounted from the shaft 1. Stepped work is performed over the whole periphery on end parts 2a and 2b of the sleeve 2, and the whole periphery-integrated cylinder 4 is fitted in a stepped part 3, and the sleeve 2 is fixed to the shaft 1. An outside diameter (a) of this cylinder 4 is set almost equal to or smaller than an outside diameter (b) of the sleeve 2 and smaller than an inside diameter (c) of the bearing 5.  Therefore, since a projecting material having a diameter larger than an inside diameter of the bearing 5 does not exist on the shaft side, the shaft 1 can freely move in the shaft direction, and since a set bolt 7 is arranged in the integrated cylinder 4, even if a load by thermal deformation is applied, the possibility of damaging the bolt 7 is extremely reduced.

Title: Cooling structure for heating component
Inventor: MOCHIZUKI MASAHIRO
IPC: H01L23/473
Filed: 1990-10-31
Abstract: PURPOSE:To protect an LSI against breakdown by arranging a cooling element oppositely thereby canceling the pressing force to be imposed on a heat sink upon variation of pressure of cooling medium. CONSTITUTION:Protrusion of a heat sink 14-3 of an LSI 4-2 is inserted between heat transmission boards 2-2 of an opposing cooling elements 2 with the heat sink 14-3 being fastened to the side faces of-the opposite end members 11-1 and an intermediate member 11-2 of a cooling structure, and the protrusion is pressed resiliently by the element 2 against the heat transmission boards 2-2 on the opposite sides thereof. Consequently, even when the pressure of cooling medium ejected into the element 2 varies to increase pressing force, variation of force for pressing the protrusion of the heat sink 14-3 is canceled and the LSI 4-2 is protected against breakdown due to pressure variation. Furthermore, since the protrusion of the heat sink 14-3 can be made high and the area of the heat transmission board 2-2 can also be increased, heat transmission areas of the LSI 4-2 and the element 2 can be enlarged.

IPC: G11B21/10
Filed: 1990-11-05
Abstract: PURPOSE:To position a magnetic head correctly on a target track against disturbances such as vibrations and shocks by controlling a head moving mechanism with a signal obtained by differentiating the difference signal between the signal, which is obtained by differentiating a position signal by twice or more and suppressing the high-region component, and the basic control signal obtained by the operation of servo data on a magnetic disk. CONSTITUTION:The position of a magnetic head in the direction of the radius of a magnetic disk 2 is detected with an optical sensor 8. The obtained position signal is differentiated by twice or more with a differentiator 16. Then, the high-region component of the differentiated output signal is suppressed with a filter means 17. The difference signal between the output signal of the filter means 17 and the basic control signal obtained by operating the position-error signal based on the data in the magnetic disk is obtained with an operation amplifier 18. The difference signal is integrated in an integrator 19, and the control signal for a head moving mechanism 4 is obtained. Thus, the position of the magnetic head can be correctly determined for a target track against the disturbances such as vibrations and shocks.

Title: Semiconductor laser element
Inventor: YAMASHITA SHIGEO
IPC: H01S5/00
Filed: 1987-11-27
Abstract: PURPOSE:To obtain a semiconductor laser having suitably wrong coherency, narrow horizontal beam spreading angle and low noise by increasing the width of a stripelike protrusion shape wide near a reflecting face of the side for irradiating an optical beam, and smoothing its variation, thereby operating its pulsation. CONSTITUTION:The center of a laser has a width W1 of a photoconductor, this region is formed in a structure for effectively generating a pulsation, the vicinity of at least one reflecting face is widened to W2>W1, and a beam spreading angle is corrected in this region. The transfer from the width W1 to the W2 is smoothly performed. The beam spreading angle can be arbitrarily set by altering the width W2 of an optical guide near the reflecting face, i.e., the width of the stripelike protrusion shape provided at a semiconductor clad layer. Thus, the pulsation effectively occurs, thereby obtaining a semiconductor laser element having suitably wrong coherency, a narrow beam spreading angle adapted to be coupled with an optical system, low threshold current value and low noise in a low yield.
