Patent JP-H02266217-A (JP)
Title: Optical fiber gyroscope
Inventor: MATSUDA YOSHIKAZU
IPC: G01C19/72
Filed: 1989-04-07
Abstract: PURPOSE:To keep the polarized component of light wave propagated in a fiber coil and to prevent fluctuation in a polarization direction from occurring by using a polarization maintaining fiber for the fiber coil. CONSTITUTION:Light emitted from a light source 1 passes through an optical coupler 4 and reaches the fiber coil 7. In this case, the polarized state of the light made incident in the coil 7 is decided in accordance with optical constitution which means from the light source 1 to the coupler 4. The polarized components out of the light made incident in the coil 7 is separately propagated in the coil 7 as (x) polarized wave and (y) polarized wave. Since the length of the coil 7 is set longer than coherent length, the (x) polarized wave and the (y) polarized wave are made incoherent and do not interfere with each other. Non-polarized component of the light wave is separated to the (x) and (y) polarized waves to be propagated. Then, clockwise light and counterclockwise light propagated in the coil 7 are synthesized by a 2nd coupler, and the (x) polarized wave and the (y) polarized wave which are incoherent do not interfere with each other, so that the (x) polarized waves of the light mutually interfere one another and the (y) polarized waves of the light mutually interfere one another. Therefore, the polarized component is kept.

Title: Method and apparatus for detecting condition
Inventor: YAMAKI ISAO
IPC: F02D29/02
Filed: 1980-07-01
Abstract: PURPOSE:To detect a condition of a slip of a wheel without using acceleration signals by comparing false speed signals, a rising rate thereof is limited to a fixed value, with the speed of the wheel. CONSTITUTION:Wheel speed signals VW obtained by means of a F-V converter 2 are changed into signals higher only by DELTAV by means of an adding circuit 3. The signals are inputted to a +G gradient limit circuit 4, and used as the false speed signals VT. The signals are inputted to a comparator 5 together with the wheel speed signals VW. When the wheel speed signals exceed the false speed signals VT, slip signals S are outputted, and a driving force reducer 7 is operated. Since the false speed signals VT are set employing a limit of the acceleration of a car as the reference, the wheel can be decided as being brought to the condition of the slip when the speed of the wheel exceeds the signals VT, and malfunction is not generated because the acceleration signals are not used.

Title: Manufacture of solid-state electrolytic capacitor
Inventor: IIDA KAZUYUKI
IPC: H01G9/04
Filed: 1989-04-07
Abstract: PURPOSE:To increase capacitance and improve leakage current characteristics by performing heat treatment after a first anodic oxidation, and then performing a second anodic oxidation applying the higher voltage. CONSTITUTION:After a first anodic oxidation, a sintered body is subjected to a heat treatment, and then a second anodic oxidation is performed by applying a voltage higher than the first anodic oxidation. That is, the first anodic oxidation is formed by applying a voltage about 2-3 times the rated voltage, and electrostatic capacitance is made comparatively large. After the first anodic oxidation, leakage current is reduced by heat treatment. After the heat treatment, the second anodic oxidation is performed by applying a voltage higher than the first anodic oxidation, thereby selectively forming imperfect parts of an oxide film generated by heat treatment and the like. Thereby electrostatic capacitance can be increased, and tandelta characteristics, leakage current characteristics, etc., can be improved.

Title: Drive mechanism for remote control mirror for automobile
Inventor: KAWAMOTO NAOTO
IPC: G02B7/182
Filed: 1995-04-14
Abstract: PURPOSE: To reduce the size and the weight of a clutch mechanism located at a transmission system between a drive motor and a moving forward and backward lever by modifying the drive mechanism of a remote control mirror for an automobile, to improve operation reliability and durability, and to stabilize slide operation of a clutch. CONSTITUTION: A gear train is arranged between a drive motor 2 and a male screw 11 to feed a moving forward backward lever by a screw. A clutch mechanism 16 is located between the intermediate gears 14 and 15 of the gear train to form a subassembly. Since a clutch mechanism is arranged in the middle of a reduction transmission system, transmission torque of the clutch mechanism being lower than that of a conventional type where a clutch is arranged at the stage preceded by a reduction transmission system suffices for operation. Thus, even when the size and the weight of a clutch mechanism are reduced, reliable operation is practicable.

IPC: G11B20/10
Filed: 1985-04-26
Abstract: PURPOSE:To attain accurate control by using a difference between the emitter voltage of the 2nd transistor (TR) and a held peak value as a control signal. CONSTITUTION:A capacitor C2 is functioned as a peak holding circuit. The voltage between the base and emitter of the 2nd TR Q2 is equal to that of the 1st TR Q1 and the emitter of the TR Q2 is earthed by a resistor R22. Since the working point of the TRs Q1, Q2 is set up to a bias voltage Vb, the emitter output of the TR Q1 is based upon Vb-VBE and the capacitor C2 is charged with the emitter output. On the other hand, Vb-VBE is serially outputted to the emitter of the TR Q2 and the output voltage Vc of a difference voltage generating circuit D offsets also the value of the VBE independently of the bias voltage Vb and is precisely proportional to the amplitude of an input signal. Consequently, a control signal precisely proportional to a reading signal can be obtained and accurate control can be attained.
