Title: Magnetic disk device
Inventor: KOMAI YASUNORI
IPC: G11B33/14
Filed: 1990-03-13
Abstract: PURPOSE:To remove dust positively through the use of a differential pressure between outside and inside of casing by providing a suction and a suction air filter to a position under a lowest negative pressure in the casing and providing a delivery port and a delivery air filter to a position under a highest positive pressure with respect to an external atmospheric pressure. CONSTITUTION:A suction port 11 is provided to a casing 1 at a position under a lowest negative pressure with respect to an external atmospheric pressure in the casing 1, a suction air filter 12 removing dust to the suction port 11 or in the vicinity thereof, and on the other hand, a delivery port 13 is provided to a position under a positive pressure with respect to an atmospheric pressure in the casing 1 and a delivery air filter 14 removing dust to the delivery port 13 or in the vicinity thereof. Thus, the dust in the air taken in the casing 1 from the suction port 11 by a differential pressure between the inside and the outside of the casing 1 is removed by the suction air filter 12, and when the air is delivered from the delivery port 13 externally by the differential pressure between the inside and the outside of the casing 1, the dust in the casing 1 is removed by the delivery port air filter 14. Thus, the dust removal efficiency of the air filter is improved.

Title: Float area type flowmeter
Inventor: URATA EIZOU
IPC: G01F1/22
Filed: 1979-05-22
Abstract: PURPOSE: To enable the measurement of the flow rate of fluid with small indication errors by measuring the fluctuations in the height of an area control plate owing to the pressure differece of the time when fluid passes in the annular channel between a varied-sectional area pipe and are control plate.  
     CONSTITUTION: The fluid influent from an influent port 1 passes the spacing between a varied-sectional area pipe 2 and area control plate 3 and flows out from the effluent port 4 in the lower part. The area control plate 3 and float body 5 are firmly coupled by means of a connecting material 6 and its mean specific gravity is made smaller than that of the liquid, so that at the time when the liquid passes the annular channel between the varied-sectional area pipe 2 and area control plate 3 owing to the fluid inflow, a pressure drop is generated and the pressure difference thereof causes the float 5 to fall and balance. The height X of the area control plate 3 of this case is known visually through the varied-sectional area pipe 2 manufactured by transparent material, whereby the flow rate Q is obtained.

Title: Magnetic shielding structure
IPC: H05K9/00
Filed: 1991-03-05
Abstract: PURPOSE:To prevent magnetic penetration through an opening of a shielded space, by piling cylindrical ferromagnetic members with spaces among them in a concentric way and placed them at an opening of the shielded space. CONSTITUTION:A shielded space, where a given space is surrounded with a ferromagnetic material, has an opening. At the opening part, cylindrical members made of ferromagnetic material having their openings in the same direction as the opening of the shielded space are formed in a concentric pile with spaces d1 and d2 between them. Then, the shape of the piled cylindrical members in cross section is made equal to that of the opening part, which has a circular or polygonal shape. Since a magnetic field comes inward from the end of the opening in this cylindrical member group along the spaces d1 and d2 between them, the diameter R. of the ferromagnetic cylindrical members is so designed that the inside intensity of the magnetic field becomes uniformly equal at the outlet opening, i.e., at z=L. In this way, the spaces d1 and d2 are also determined, and thereby the magnetic penetration can be minimized.

IPC: G01N21/47
Filed: 1993-02-26
Abstract: PURPOSE:To detect an object highly accurately by enhancing the power for discriminating between noise and reflected light from the object thereby enhancing noise resistance. CONSTITUTION:The object detector comprises a light emitter 21a for emitting an optical pulse signal toward a measuring space, and a light receiver 21b for receiving a reflected optical signal from the observing space.

The assembly is fabricated as follows: secondary squeezing is performed to form a stepped bowl-shaped workpiece. Thereafter, extrusion is performed using a press to form a workpiece with projections and recesses alternately formed on its side wall. Last, the projections on the circumference of the workpiece are removed to the same level as the recesses using a press or a machining tool such as lathe as appropriate. Thus a brake yoke 1 with the salient pole portion 1A integrally formed on its inner circumferential surface and further the boss with key way integrally formed is completed.

Title: Diffusion to semiconductor substrate in sealed tube
Inventor: NAGASAKA SHIYUUICHI
IPC: H01L21/223
Filed: 1981-04-28
Abstract: PURPOSE:To prevent semiconductor substrates from attachment of an undesired diffusion material by a method wherein the semiconductor substrates and diffusion sources are arranged by facing each other in a vacuum sealed tube  through a silicon plate formed an oxide film on the main surface and heating is applied. CONSTITUTION:An oxide silicon layer 13b is formed on the surface of a polycrystal plate 13a of a plate-shaped silicon member 13 mounting a supporting base 2 supporting many silicon substrates. Polycrystalline plates 23 for supporting a diffusion source material are arranged by separating each other at the lower part of the member 13 and gallium layers are formed at the rear surfaces of the plates 23. Even if gallium is diffused and transmitted to the plates 23, the silicon substrates 1 are completely isolated from the gallium by the layer 13b of the plate-shaped silicon plate 13. Therefore, undesired gallium will not attach to the silicon substrates 1.

Title: Air-filled fixed type fender
Inventor: NAKANISHI MASANORI
IPC: E02B3/26
Filed: 1980-05-15
Abstract: PURPOSE: To allow the outer surface of an outer surface wall to be retained flat on the plane under filling a internal pressure without use of a rigid core material or the like by reinforcing the outer surface wall with a outer rubber layer through a reinforcing layer along the inner surface of a shell body dividing an internal hollow.  
     CONSTITUTION: An air bag body 1 secured on a quay is made of an elastic material and a rigid shell reinforcing layer 3a and an end reinforcing layer 3b are buried along the inner surface of the shell 1. An outer rubber layer 12 is formed on the end wall 2 in such a manner as to increase outward gradually as to the thickness in a radial direction. When an internal hollow C divided by the shell 1 and the outer surface wall 2 is filled with an air of a specified internal pressure from a ventilation path 9, the outer rubber layer 12 gets thicker toward the periphery of the wall 2 causing a strong circumferential compression stress, which checks the deformation of the air body. This fender provides a flat impact receiving surface, resulting in a larger area even initially in the distortion, ensuring a greater absorption of energy caused by berthing of a ship.
