Title: Optical wavelength multiplex recording and reproducing device
Inventor: ASAZUMA YASUNORI
IPC: G11B7/005
Filed: 1993-11-08
Abstract: PURPOSE:To make recording and reproducing possible with simple constitution and to reduce the size and cost of the device by constituting an optical member of a specific combination. CONSTITUTION:The recording light from a light source section 1 is reflected by a deflection beam splitter 2, is passed through a quarter-wave plate 24 and is cast to an optical wavelength multiplex recording medium 4 and recording is conducted by a two photon recording method at the time of recording. The reflected light is again passed through the quarter-wave plate 24, is rotated 90 deg. in the plane of polarization and is transmitted through the deflection beam splitter 2 to avert the return beam to the light source 1 section. At this time, the return beam is partly reflected by a polarization beam splitter 23 and is supplied to a detecting section 28, by which a servo signal is obtd. The linearly polarized light from the light source section 1 is cast to the recording medium and the return beam is again passed through the quarter-wave plate 24 to rotate the plane of polarization by 90 deg. and is made incident on the photodetecting part 3 through the deflection beam splitter 2, by which recording information is obtd. at the time of reproducing. The device is simply constituted and the size, weight and cost of the device are reduced by combining the light source lens, the beam splitters and the quarter-wave plate.

Title: Spacer for speaker
Inventor: WATANABE SHUICHI
IPC: H04R1/22
Filed: 1991-09-30
Abstract: PURPOSE:To prevent sound quality from being degraded by suppressing the increase of a sound pressure level in middle and high sound areas by providing a resonator at one part of the main body of the spacer. CONSTITUTION:A spacer 10 is composed of a head part 12 and a body part 13. In the case of assembly, a recessed part formed at the lower edge part of the head part 12 is fitted to an upper edge part equipped with the flange part of the body part 13, and these joint parts are fixed by an adhesive agent or the like. A cavity 17 is formed at the upper edge part of the body part 13. Six ports 18 communicated to the cavity 17 are formed at the flange part of the upper edge part. The resonator is composed of the cavity 17 and the ports 18. Thus, since the resonator is provided at one part of the main body of the spacer 10, a resonance frequency can be easily increased or decreased by changing the capacity of this resonator or changing the shapes of the ports 18 and the number, for example. Further, by dividing the resonator so as to have respectively different resonance frequencies, the sound pressure level in the middle and high sound areas can be decreased over a low band.

Title: Inverter device
Inventor: KUBOTA SATOSHI
IPC: H02M7/5383
Filed: 1989-10-26
Abstract: PURPOSE:To automatically restart an oscillation by stopping ON, OFF of a second switching element when the oscillation of an inverter is stopped to wait until the capacitors of commutation and resonance circuit are discharged, and then operating a controller. CONSTITUTION:A momentary power interruption, etc., occurs in a state that the storing charges of capacitors C0, C1 are charged to the voltage of a DC power source E, a transistor Q1 is turned OFF, and an oscillation is stopped. Here, it is so set that the capacitors C0, C1 are sufficiently discharged during a period in which the output of a monostable multivibrator 8 is a low level. Accordingly, when the output of the multivibrator 8 becomes a high level and a FET Q2, is turned ON, a current flows to the primary winding of a drive transformer T1 to turn ON the transistor Q1. Thus, the oscillation of an inverter can be automatically restarted without turning again ON the power source.

Title: Invariable mirror for high-output laser
Inventor: YASUDA KOZO
IPC: G02B5/08
Filed: 1989-10-26
Abstract: PURPOSE:To obtain the invariable mirror for a high-output laser for preventing the degradation in the quality of a laser beam generated by the thermal deformation of a mirror by absorption of the laser beam by joining an extremely low expanding material and a high thermal conductivity material and forming the surface of the extremely low expanding material as a specular surface. CONSTITUTION:The material 6 having an extremely low coefft. of expansion, such as 'Invar(R)' or 'Super Invar(R)', is used on a polished mirror surface (specular surface) side and the high thermal conductivity material 7, such as copper or aluminum, is used on the rear surface which is a cooling side. Both are diffusion joined or solder joined, by which a completely joined clad material is formed. This material is used as a blank material. The coefft. of the linear expansion of the extremely low expanding material, for example, 'Super Invar(R)', is 4 X 10<-7>( deg.C)<-1> and is smaller by two digits than the coefft. of linear expansion of ordinary metallic materials. The thermal deformation of the mirror is, therefore, prevented. The thermal deformation of the extremely low expanding material is obviated in this way even if the laser beam is made incident to this material; in addition, the heat absorbed in the extremely low expanding material is rapidly removed by the high thermal conductivity material.

IPC: F16H61/14
Filed: 1996-09-30
Abstract: PROBLEM TO BE SOLVED: To make responsiveness compatible with stability by performing control based on an IPD control rule when a slip deviation is large and, during a normal running thereafter, performing control based on a musynthesis control rule. SOLUTION: An automatic transmission 10 includes a torque converter 20, a transmission mechanism driven by the output of the converter 10 having first and second planetary gear mechanisms 30 and 40 and friction elements 51 to 55 for switching power transmission routes in the planetary gear mechanisms 30 and 40 and one-way clutch. For slip-controlling of the torque converter 20, a slip rate is controlled by feed forward control when a slip rate exceeds a specified value. When a slip rate is lower than the specified value and there is a large slip deviation, a slip rate is controlled based on an IPD control rule for providing good responsiveness. On the other hand, when a slip rate is small, a slip rate is controlled based on a musynthesis control rule for providing much higher stability.
