Title: Optical fiber type magneto-optical head
Inventor: HORIE MAKOTO
IPC: G11B7/1384
Filed: 1989-06-02
Abstract: PURPOSE:To reduce the size and weight of the moving part of the optical head by interposing an optical rotatory element between an optical means and a polarization plane maintaining optical fiber and specifying the one optical rotating angle of the polarization plane. CONSTITUTION:The optical rotatory element 28 is interposed between the optical means and the polarization plane maintaining optical fiber 26 and the one optical rotating angle of this optical rotatory element 28 is so determined as to attain equation I. Light having a polarization characteristic is emitted from the polarization maintaining optical fiber 26 while the polarization plane thereof is maintained. This light transmits the optical rotatory element 28 and after the polarization plane thereof is rotated by thetaA/2 deg., the light is projected to a magnetic recording film 2b. The projected light is rotated in the polarization plane by + or -thetaK according to the magnetization direction of the magnetic recording film 2b and is transmitted again through the optical rotatory element 28, by which the polarization plane is further rotated by thetaA/2 deg. and thereafter, the light is passed through the polarization plane maintaining optical fiber 26 and is detected by a detector 32. The stationary part 20 of the optical head and the moving part 30 of the optical head are, therefore, connected by the one polarization plane maintaining optical fiber 26. The higher speed of the optical head is obtd. in this way and the size thereof is reduced.

Title: Braking device for vehicle
Inventor: IKEGAMI HIROSHI
IPC: F16D65/14
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To suppress vibration at the time of actuating a brake by connecting a piezoelectric element to a braking device for braking a vehicle, and connecting load to the output end of the piezoelectric element. SOLUTION: A ventilated disc 1 is formed by connecting two discs 1b, 1b of doughnut shape by rib-shaped connecting bodies 1a so as to have a cavity communicated from the inner peripheral side to the outer peripheral side. A piezoelectric element 2 is interposed in this cavity in such a way as to bridge the discs 1b, 1b. The piezoelectric element 2 is held by electrodes 3a, 3a, and an output end 3 is connected to the electrodes 3a, 3a. A light emission diode 4 to be load is connected to the output end 3. When a brake is applied, the ventilated disc 1 is distorted in a direction of an arrow mark F. The piezoelectric element 2 therefore receives distortion repeatedly to start power generation. Generated electric power is consumed as light at the light emission diode 4 to be load.  At this time, compliance of the piezoelectric element 2 is lowered, and resistance to the distortion is generated to suppress vibration at the time of actuating the brake.

Abstract: PURPOSE:To improve linearity at the time of large amplitude and to improve the acoustic conversion efficiency by reducing the pressure inside the air chamber by providing a pressure reduction device, and adding a device to return deviation of diaphragm caused by the pressure differential with the atmospheric pressure to the position of the center of action. CONSTITUTION:The air chamber 1 is maintained air-tight by an enclosure 11. The pressure in the air chamber 1 is controlled to reduce by an air pump 12 by extracting at least ten times of the volume of air which is pushed away by the diaphragm by its stroke from the position of the center of action at the time when signals are lacking to the maximum rear shifting position. To a cancell spring 3 connecting between a bridge 4 and the diaphragm 2, a tension to pull back the diaphragm 2 that shifted to the rear caused by a pressure applied to the diaphragm 2 itself due to the pressure differential between the enclosure 11 and the atmosphere associative with the pressure reduction in the air chamber to the position of the center of action, is supplied. As a result, the reduction of pressure in the air chamber 1 can be enabled with the diaphragm being maintained in the position of the center of action, hence the air stiffness in the air chamber can be reduced.

Abstract: PURPOSE:To easily cut-off the supply of heat to indoor side, when heating is unnecessary, by a structure wherein the evaporation end of a heat pipe is arranged on the exterior surface of a building and its consensor end is arranged in the building and a valve device is provided between the ends. CONSTITUTION:A coolant absorbs the heat of vaporization and evaporates at the evaporation end 1a, which contacts with an absorber panel heated by solar heat of the heat pipe 1 and travels due to pressure difference to the condensor end 1b and condenses there by giving up its heat to a floor heating panel 4 and travels back to the evaporator end again by gravity. By such a cycle as mentioned above, the heat collected by the absorber panel 3 is transported to the floor heating panel 4 in order to heat a room. When no heating is required, the interior of the room is eliminated from being heated by turning-ON the power supply of a power supply cord 11 so as to actuate an electromagnet 10 in order to bring a valve body 8 into close contact with a valve seat member 7, resulting in cutting-off the flow of the coolant of the heat pipe 1.

Source and drain regions 28a and 28b are formed, and a masking material layer 31 having the property of selective etching to the insulation film 27 is formed over the whole surface; thereafter, this masking material layer is selectively removed until the remaining insulation film 27 on the side surface of the gate electrode is partly exposed. A gap is formed between the gate electrode by selective removal of the remaining insulation film 27 using the remaining masking material layer. The third impurity layers 34a and 34b of the first conductivity type are formed by introducing an impurity to the substrate through the gap.

Title: Oscillatory type angular velocity detecting device
Inventor: KATOU KENJI
IPC: G01C19/5649
Filed: 1984-07-09
Abstract: PURPOSE:To maintain the high precision of detection of an angular velocity without any error in amplification detection level with time by providing an amplifying means with an electric element which varies in amplification factor with ambient temperature similarly to the electrostatic capacity of the 2nd piezoelectric element. CONSTITUTION:An electric circuit 20 connected to an oscillation member 10 is equipped with an operational amplifier circuit 23 connected to a piezoelectric element 15. When an angular velocity is omega=0, the piezoelectric element 15 outputs a drift quantity based upon disturbance as a detection signal and then an operational amplifier 23a generates an amplified detection signal amplified with an amplification factor K in cooperation with capacitors 23b and 23c. Namely, the electrostatic capacity (amplification factor K) of the capacitor 23b varies with temperature similarly to the electrostatic capacity of the piezoelectric element and the amplified detection signal level of the amplifier 23a becomes nearly constant corresponding to the drift quantity without reference to temperature variation. Its output is supplied to an amplifier 27 through a synchronous detector 25, etc. Therefore, the angular velocity signal of the amplifier 27 is a precise value corresponding to omega=0.

Title: Detector for condition of printer
Inventor: HITOMI MASAAKI
IPC: B41J29/46
Filed: 1979-11-02
Abstract: PURPOSE: To provide the detector which ensures the returning of a carriage by generating an abnormality signal as long as a printing head fails to return to a home position in a serial printer.  
     CONSTITUTION: As soon as the printing head 3 starts returning initiated by the return action of the carriage, a busy signal is generated so that the printing head is returned in a reduced speed at the moment the head 3 passes the second position detecting element 2. Then, when the printing head 3 is returned to the home position, the timing is detected with the first position detecting means 1 while an informing means produces an information signal to indicate the end of the carriage returning. Here, only when the first position detecting signal coincides the information signal, the busy signal is vanished. On the other hand, while the first position detecting signal fails to be generated, an abnormality signal generating means produces an abnormality signal to detect whether the printing head stays at the home position correctly. This can prevents deviation in the position of starting the printing.
