Filed: 1997-11-05
Abstract: PROBLEM TO BE SOLVED: To provide a tracking method precisely performing tracking even when an angle between a polarization direction of laser luminous flux and a track groove is fluctuated due to turning of a coarse adjusting arm.

IPC: H03F1/30
Filed: 1998-11-10
Abstract: PROBLEM TO BE SOLVED: To compensate the distortion characteristic against a change of the ambient temperature. SOLUTION: This semiconductor circuit includes a compensation circuit which combines a thermistor Rt1 which has the negative temperature characteristic and changes its resistance value according to its ambient temperature in order to compensate the distortion that is caused by the ambient temperature of the signal outputted from an FET Q1 with a thermistor Rt2 which has the positive temperature characteristic and changes its resistance value according to its ambient temperature. This combination of both thermistors is set to minimize the current that flows at a reference temperature. As a result, the increase of distortion can be suppressed or prevented against a change of the ambient temperature.

Title: Steering angle control device for vehicle
Inventor: IWAMOTO HIDEO
IPC: B62D137/00
Filed: 1991-12-03
Abstract: PURPOSE:To obtain a stable vehicle characteristic without giving any uneasy feeling to a driver by preventing the steering characteristic of 4 WS from being characterized in over steering on account of execution of control, even though the handle angle is constant. CONSTITUTION:A yaw rate object value setter 4 sets a steady characteristic by means of a linear steady yaw rate gain object value setter 4a, a steady yaw rate gain limiter 4b, and a yaw rate steady object value setter 4c, by using a standard model. The limiter 4b limits the steady yaw rate gain with a control amount according to a car speed V beforehand, and thereby, the steering characteristic of the vehicle is prevented from being shifted to an oversteering characteristic side by carrying out a steering angle control. Even though a designer increases the yaw rate gain by aiming at possibility of turning a vehicle a smaller steering angle input on a low speed side, as for the setting of the steady yaw rate gain of the standard model to be an operation object, the steering characteristic is never placed in an oversteering condition, and consequently, it never suffers from fluctuation of its change.

Abstract: PURPOSE:To prevent a reduction in cooling capacity and a dew formation of a fan by a method wherein a thermal insulation layer is arranged between an indoor fan and an outdoor fan of a single fan which is rotatably extended over an indoor aeration circuit and an outdoor aeration circuit. CONSTITUTION:Indoor air sucked from an indoor suction port 9 passes through an upper part of a heat exchanger 8 acting as an evaporator, then the air is supplied as cold air from the indoor blowing port 10 into a room by an indoor fan as indicated by an arrow A.

Abstract: PURPOSE:To obtain an optical resonator for oscillating a laser light of low order mode without using a diaphragm by providing reflecting faces having different reflectivities on one of two mirrors opposed through a laser medium commonly with optical axes by concentrically limiting the optical axes. CONSTITUTION:An optical resonator 1 is composed by interposing a laser medium 3 between a rear mirror 5 and an output mirror 7 matched at the optical axes, the rear mirror 5 is coated with a total-reflecting film on the part M1 from the center of the optical axis to a radius omega, the periphery M2 is coated with a non-reflecting film, and the output mirror 7 is coated with a translucent film on the whole surface. Accordingly, since the rear mirror 5 reflects only on the part M1, an oscillation of a laser beam of TEM01 deg. mode is suppressed, but only a laser beam of TEM00 mode is oscillated. As a result, an optical resonator for oscillating a laser beam of low order mode can be obtained without using a diaphragm.
