Title: Projection picture display
Inventor: YAMAGISHI NARUMASA
IPC: G02F1/13
Filed: 1998-04-14
Abstract: PROBLEM TO BE SOLVED: To enhance reliability against heat generated around a light bulb in a transmission projection picture display constituted of the light bulb utilizing polarized light. SOLUTION: This projection picture display 200 is constituted so that a picture is displayed by regulating random light emitted from a light source 205 to unidirectional polarized light by an incident-side polarizing plate 207, controlling the polarizing direction thereof for each pixel by the light bulb and transmitting the polarized light only in one polarizing direction by an emitting-side polarizing plate 209, enlarged and projected by a projection lens 203. Since the plate 209 is a reflection polarizing plate and inclined with respect to the surface of the light bulb, heat is suppressed from being generated near the light bulb and the plate 209. Thus, deterioration of reliability is suppressed. Besides, the deterioration of a picture caused by dusts is suppressed by applying a dust-proof structure by hermetically sealing a gap between them.

Title: Manufacture of diaphragm
Inventor: KUNIYOSHI MASAAKI
IPC: B24B19/00
Filed: 1988-04-27
Abstract: PURPOSE:To eliminate replacement of grinder element even though its tip has worn by setting the wall thickness of the cylindrical portion of a grinder element of straight cup type, which is designed to bore round holes, to a dimension below the allowable value of the radius of roundness at the peripheral part of the bottom of round hole. CONSTITUTION:When a round hole 5 is bored in a silicon mono-crystal base board 4 (here the max. allowable value for the radius of roundness at the peripheral part of the bottom of round hole 5 is set to approx. 0.25 mm), revolution round its own axis is performed in the direction of arrow 6 round a shaft 3 as rotating while orbiting is made in the direction of arrow 8 with the point 7 as the center of orbiting. This planetary motion of grinder element provides a required round hole 5. Here the peripheral part of the tip of the body 1 wears to get roundness with progress of processing. Consequently the intersection 11 of a diaphragm 9 and side wall will have roundness. As the wall thickness of the body 1 is approx. 0.25 mm, however, the radius of the roundness at this intersection 11 does never exceed 0.25 mm to lead to satisfaction of the design criterion.

Title: Light propagation device using optical fiber
Inventor: MIYAZAKI SEIJI
IPC: G02B6/293
Filed: 1978-08-25
Abstract: PURPOSE:To obtain light propagation device capable of branching and coupling or branching and multiplying the light at a small loss, by disposing two of a plurality of optical fibers in a mutually orthogonal manner. CONSTITUTION:Optical fibers 1, 4 are disposed so as to be orthogonal to each other as shown in the drawing. And the light is transmitted from A in the direction of the arrow, part of the light transmitted from A to B penetrates through a semi-transparent film 7, and is sent into the optical fiber 1 from B to C, while the other light is reflected by the semi-transparent film 7, and is sent to D on a semi-transparent film 8 of the optical fiber 4 from B to be reflected again by the semi-transparent film 8 to be sent into the optical fiber 4 from D to E. Thus, the light propagates through the optical fibers 1 and 4 and is branched. Besides, such branched lights are made to converge by the lens action due to the curvature of the side faces of optical fibers 1, 4, so that the light may be branched or propagated at a small loss.

Title: On-off state detection sensor
Inventor: FUJIEDA TAKASHI
IPC: G01V9/00
Filed: 1986-05-02
Abstract: PURPOSE:To reduce the installation cost by measuring light transmitted through a gap and detecting variation in optical transmission loss due to the gap. CONSTITUTION:Optical fibers 1 and 2 are provided having end surfaces 1a and 2a opposite each other across the gap and both optical fibers 1 and 2 are fixed by optical fiber fixing members 3 and 4. Then, when an abutting part 12 abuts on a door which is open, a force operates as shown by an arrow A and the member 3 is pressed through a nut 10 to move toward the other member 4. This movement presses an outside pipe 7 and a coil spring 9 in compressing directions and the gap between the end surfaces 1a and 2a becomes small, so that the optical transmission loss DELTAP also decreased accordingly. For the purpose, light transmitted from one optical fiber to the other is measured to find the optical transmission loss due to the gap, whose width is calculated to decide an on-off state, i.e. whether the door is open or closed from whether or not the width is larger than a set value. Thus, the installation cost is reducible.

Title: Pressure oil supply device for active suspension
Inventor: NISHIO MASAHIRO
IPC: B60G17/015
Filed: 1989-04-21
Abstract: PURPOSE:To reduce pump load in a pressure oil supply device by detecting whether vehicle attitude change is less or not, and lowering the discharge pressure of a variable capacity pump when the change is less. CONSTITUTION:A car speed V detected by a speed sensor 4 is supplied to an electronic controller 6 and is compared with a required value V0 thereat. In the case that V<V0 and there is no need for an active suspension system to function under less change in posture of a car, an electromagnetic valve 10 is exited and a part between pots 10a, 10b are made in non-communication condition. Thereby, the pressure in an hydraulic chamber 22 is released through a throttle 12 and the pilot pressure in a tube 18 changes over a valve 16 in communication condition. As a result, if the pressure in the tube 18 is higher than a relatively low reference pressure, a slant plate 24b erects and the discharge amount of a variable displacement pump 24 decreases while it increases if lower. It is thus possible to alleviate the load of a pump.

IPC: B24B1/00
Filed: 1983-06-08
Abstract: PURPOSE:To facilitate discrimination between cutting streaks and a glass member having an exceedingly thin width and reduce the abrasion of a grindstone by feeding a rectangular parallelepiped composite member equipped with the glass member with a certain cutting-in amount in the direction inclined with respect to the direction crossing at right angles with the revolution shaft of a disc-shaped grindstone having a circular outer peripheral part. CONSTITUTION:A glass member 18 having an exceedingly thin width is set at the center of a rectangular parallelepiped composite member 17 and reinforced by glass members 19 and 20 from both sides. When the composite member 17 is fed with a certain cutting amount F with respect to a grindstone 15 in the direction 24 inclined by an angle theta for the direction 23 crossing at right angles to the revolution shaft 16 of the grindstone, the lowest point on the grindstone 15 on the straight line separated by a certain distance (d) in the direction 25 crossing at right angles to the direction 24 is copied onto the composite member 17. If the curvature molding grinding method is applied onto the composite member 17, the longitudinal direction of the glass member 18 having an exceedingly thin width and the direction of cutting streak form a certain angle theta, and therefore, the both can be discriminated very easily, and each point on the surface of the grindstone 15 performs uniform cutting, and generation of local abrasion is prevented.

Title: Valve spring for interenal combustion engine
Inventor: HARA NOBUO
IPC: F01L3/10
Filed: 1997-04-21
Abstract: PROBLEM TO BE SOLVED: To minimize abrasion of a retainer, by extending end part of the top of a coil-shaped valve spring whose upper end's winding diameter shrinks gradually upward and top part's winding end is flat in the direction far away from a central axial line. SOLUTION: In a bell-shaped valve spring 1 which is used for a valve system of an internal combustion engine, its top part's winding end is flat and is placed on a bottom surface of a retainer 2, and its end part 9 is extended substantially in the tangent direction far away from a central axial line. Alternatively, the end part 9 is extended outward with substantially same curvature as lower end's winding diameter of the valve spring 1. Because this extension of the end part 9 far away from the central axial line enlarges gap between an inner peripheral edge with acute angle of the end part 9 and a cylindrical part 2a of the retainer 2, probability that the end part 9 interferes with a connecting corner 5 between the cylindrical part 2a and a receiving surface is decreased and abrasion of this part is minimized.
