Title: Optical recording apparatus
Inventor: OTOMO KATSUHIKO
IPC: G11B7/00
Filed: 1993-12-21
Abstract: PURPOSE:To easily adjust an optical part when an optical system is assembled, by arranging a light-polarizing means for oscillating a recording beam in a diametrical direction of a disc by a high frequency signal immediately in front of an objective lens. CONSTITUTION:A laser beam source 1 generates recording beams to form a discrete data pattern and a tracking group as a preformat to an optical disc 6. An optical means having a relay lens 35 and an objective lens 8 condenses the recording beams onto the optical disc 6. A light modulator/deflector 3 modulates the recording beams by a data signal so that an area where the discrete data pattern is formed on the optical disc 6 is discretely exposed, and at the same time oscillates the recording beams in a diametrical direction of the disc 6 by a high frequency signal so that an area where the tracking group is formed is multiple-exposed. The optical modulator/deflector 3 is arranged within a predetermined range immediately before the objective lens 8.

Title: Compact differential pressure transducer and manufacture thereof
Inventor: HENRII GUTSUKERU
IPC: G01L19/00
Filed: 1991-12-06
Abstract: PURPOSE: To obtain a very small-sized differential pressure transducer. CONSTITUTION: This differential pressure transducer 20 is formed on a semiconductor base layer 21 of silicon and has a film spreading in a cavity 35 present at the upper part of the base layer. This film is mounted on the base layer at its peripheral edge and sealed. Excessive pressure suppression 36 is formed on the bottom of the cavity and prevents this film from deflecting toward the base layer. Further, an excessive pressure suppression 27 which is formed as a bridge spreads over the film. This is isolated from the base layer, so free deflection is obtained in a normal pressure state, but excessive deflection is prevented.

Title: Rotary compressor
Inventor: YAZAWA HIDEKI
IPC: F04C29/06
Filed: 1990-11-28
Abstract: PURPOSE:To secure such a quiet rotary compressor that reduces an operational noise as specified, by installing an oil escape passage means, forming a derain oil passage being interconnection to a space part at the more upper part than a level of lubricating oil, in a space between a compressor mechanical part and an electric motor. CONSTITUTION:At time of starting a rotary compressor, since oil to be discharged out of a cylinder bore 3a is discharged out of a silencing chamber 11 by way of three drain oil passage 5b, 3b, 4b, this oil is prevented from staying in this silencing chamber 11. Accordingly, any interferential noise so far produced by such a fact that compressed gas is discharged into oil in the silencing chamber 11 by way of a discharge valve 8 is thus prevented from occurring. In addition, these drain oil passage 5b, 3b, 4b serve as a suchlike effect as damping any energy of a discharge noise of gas being discharged to the discharge valve side. Moreover, a discharge direction is that of a case 16, where a stator 1b or the like of an electric motor M is clamped, and this case proper value is not accorded with a frequency band component inherent in the discharge noise and sound permeability is decreased by the stator 1b, thus a noise level in the discharge noise is reducible.
