IPC: G05D19/02
Filed: 1995-03-27
Abstract: PURPOSE: To surely reduce vibration and noise inside a car due to the operation of an engine without the influence of weather conditions and road circumstances. CONSTITUTION: A vibration noise reducing device has a shaker for generating vibration; a G sensor 6 for detecting the vibration inside a car; a microphone for gathering noise inside the car; an importance giving means 45 for severally giving importance to the signals of the G sensor 6 and of the microphone 7; and a control means 46 which generates a control signal having a phase reverse to the vibration and noise inside the car being due to the operation of an engine on the two above signals having given importance for controlling the shaker 4. The importance giving means 45 makes an importance giving factor for a signal which includes more vibration and noise due to the source except the operation of the engine than any among the signals of the G sensor 6 and of the microphone 7 smaller than the importance giving factor for other signals.  Thus the control signal having a phase reverse to the vibration and noise inside the car being due to the operation of the engine is surely generated to negate the vibration inside the car through the vibration generated by the shaker 4 for reducing the vibration.

Abstract: PURPOSE:To obtain a thermally reversible hydrophilic and hydrophobic polymer having a transition temperature different from that of a conventional thermally reversible polyacrylamide derivative and useful for a light screen for a greenhouse or a chemical laboratory, a temperature sensor, a display, etc., by radical- polymerizing a specified vinyl compound. CONSTITUTION:A vinyl compound of formula I (wherein R1 is H or methyl and R2 is a lower alkyl) is radical-polymerized to obtain a thermally reversible hydrophilic and hydrophobic polymer of formula II (wherein R1 and R2 are as defined above). This polymer has such a thermal reversibility of high- temperature hydrophobicity type that it can dissolve in water in a low- temperature range and can not dissolve in water in a high-temperature range. Although the transition temperature of the polymer varies with polymerization conditions, for example, that of poly(N-methoxypropylacrylamide) is 44-48 deg.C in a 1wt%-aqueous solution. Said polymerization is carried out preferably by a solution polymerization process. It is preferable that the degree of polymerization is 0.01-6.0 in terms of an intrinsic viscosity [eta] (as measured in a methanol solution at 30 deg.C).

IPC: G11B7/09
Filed: 1995-03-27
Abstract: PURPOSE: To realize on optical pickup device and method capable of reducing the track detecting error due to the deviation of an optical axis. CONSTITUTION: An optical disk 5 is irradiated by the luminous flux from a semiconductor laser 1 through in order of a collimate lens 2, a polarized light separating element 3, an objective lens 4, and a substrate 9 being a refractive index ellipsoid with uniaxial anisotropy such as the optical anisotropy having the main axis in the thickness direction. After the reflected light is passed through the substrate 9 and the objective lens 4, the component perpendicular to the polarization direction X of the semiconductor laser is separated by the polarized light separating element 3, then the light is received by a photodetector 6. Since the reflected light S is received on the position separated from a dividing line 8 on the light receiving surface 7, the track detecting error is reduced even when the deviation ▵S of the optical axis occurs.
