Title: Optical recording medium
Inventor: MARO TAKESHI
IPC: G11B7/2533
Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium which prevents the occurrence of film bulging when the medium is taken out of the environment of a high temp. and high humidity to the room temp. environment. SOLUTION: The optical recording medium 400 has the structure obtd. by successively laminating an intermediate layer 56, a reflection layer 51, a first dielectric layer 52, a recording layer 53 and a second dielectric layer 54 on a resin substrate 50. The intermediate layer 56 comprises an amorphous or microcrystalline material. The intermediate layer 56 is disposed between the resin substrate 50 and the reflection layer 51, by which the interposition of the gaseous components included thus far in the resin substrate 50 between the resin substrate 50 and the reflection layer 51 is obviated and the occurrence of the film bulging on the surface of the optical recording medium is suppressed.  Even if, therefore, high-density recording is executed by using near field light, the damage of the optical recording medium by interference with the optical recording medium surface at the time of traveling of a floating type head is averted.

Title: Printer
Inventor: ANDO TERUAKI
IPC: B41J13/00
Filed: 1994-11-29
Abstract: PURPOSE: To perform a full color print of high image quality even when a mounting sheet is not proper to form an image by adhering a printer sheet adapted to form the image to the mounting sheet. CONSTITUTION: The rear surface of a printer sheet M is coated with adhesive by an adhesive coating unit 1. On the other hand, a mounting sheet S desired to be printed with an image is formed by so superposing that the sheet M and the sheet S are disposed at the lower side, and adhered by pressure contact rollers 2a, 2b. The sheet M has a receiving layer having excellent sublimable dye fixing properties, and is so adhered that the layer is exposed on the front surface. When the fact that the sheet S adhered with the sheet M is moved to the print starting position is detected, an ink film IF is superposed, and pressurized between an opposed thermal head 3 and a platen 4. The dye of the film IF is sublimated to the layer 21 of the sheet M to form a first color image.

Title: Idle rotation controller
Inventor: SOSHINO MASAHIKO
IPC: F02M69/32
Filed: 1993-12-20
Abstract: PURPOSE:To alleviate collision of a jet so as to prevent generation of noise and vibration by providing curved shapes in each part of a valve outer peripheral surface and a body inner circumferential surface, respectively, in a flow rate control valve for use in an idle rotation controller for an internal combustion engine. CONSTITUTION:A body inner circumferential surface 20a is formed into such a curved shape that its diameter becomes smaller from upstream toward a throttle portion. Meanwhile, a valve outer peripheral surface 12a is formed into such a curved shape as to be enlarged toward the downstream from the throttle portion. Consequently, fluid to be injected at a high pressure passes along the body inner circumferential surface 20a of the smooth curved shape upstream of a valve throttle, to be thus gradually throttled, while passes downstream along the valve outer peripheral surface 12a of the smooth curved shape, to be thus gradually released, thereby alleviating collision of a jet.

Title: Attitude stabilizing mechanism for underwater sensor
Inventor: ONO KOJI
IPC: G01S7/52
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To avoid increasing the underwater resistance of an underwater sensor due to the attitude disturbance of the sensor, when the sensor is pulled up quickly from water. SOLUTION: During an underwater sensor 1 sunk condition, a flange shaft 8 is pressed to a lower part of a room 12 due to the elastic force of a spring 9 and hence a lower stabilizing wing 2 remains housed in the sensor 1. When the sensor 1 is pulled up, the tension of a hanging cable 3 occurs, to thereby lift the flange shaft 8 upwards against the force of the spring 9, while a plate 4 is lifted up through a shaft 7 to lift upwards a part of the lower stabilizing wing 2 connected to the plate 4 via a pin 6 and this causes the wing 2 to rotate around a pin 5, thus developing the wing 2 outside the sensor 1.

IPC: F16H57/021
Filed: 1989-12-12
Abstract: PURPOSE: To correct the contour of a bearing surface so as to compensate a rotor for bending under a heavy load, by setting an inclination and a length of a babbitt lining so as to suitably maintain an allowable minimum thickness of a lubricating oil film of a journal bearing with respect to the rotor. CONSTITUTION: The contour of a babbitt lining 13 is corrected by uniformly and linearly grinding a right lengthwise half part 28 of the babbitt lining so that the inner diameter part of the bearing is aligned with a curved line of a rotor over one half of its length. That is, the angle of the corrected contour part 28 is set to be substantially equal to a bent angle 19 of the rotor 10. The length of the corrected contour part 28 is set so that the part 28 is extended by a reasonable distance in a range from a quarter to a full of the length L of the bearing. That corrected in the contour over a length which is 60% of the full length of the bearing has a more flexibility for obtaining a suitable oil film thickness over a range in which various loads are applied, and exhibits a large allowability for installation errors causing an error in the inclination of the journal.
