Title: Optical circuit function element
Inventor: SUEMATSU YASUHARU
IPC: G02F1/025
Filed: 1985-02-28
Abstract: PURPOSE:To make possible the change-over of optical waveguides at a high speed by utilizing the change of a refractive index by the change of an energy level owing to the impressed electric field in the structure of an ultra-thin film. CONSTITUTION:Input light LIN to an optical circuit function element 10 advances rectilinearly in the 1st waveguide from an inlet 28 of an optical waveguide MQW and arrives at a light outlet 0I of the 1st optical waveguide and generates output light L0I when the voltage V impressed to an electrode 26 is 0 (V=0). The refractive index in the 1st waveguide on the lower side of the electrode 26 decreases and the light reflects at the point of the electrode and advances toward a light outlet 0II of the 2nd waveguide to produce output light L0II when the impressed voltage V is made Vnot equal to 0 (V<0). The element is thus made to act as an optical switch.

IPC: H02P29/02
Filed: 1989-02-20
Abstract: PURPOSE:To improve the reliability of automatic regulation of an electronic equipment by stopping the rotation of a motor immediately to prevent the destruction of a variable element, when said variable element reaches the termination of rotation. CONSTITUTION:A current-voltage conversion is conducted relative to a load current flowing through a motor 1 by a low resistance 10 having no effect on said motor 1 and the obtained voltage is amplified alpha times by a voltage amplifier 5 to make a small change of said load current larger and to improve responcibility of an apparatus, after a variable element 3 reaches the termination of rotation, and to facilitate detecting said termination. When an input signal is L in an FF 8, an output signal is also L and a relay 4 remains ON. That is, the motor 1 continues rotation. Then, when said input signal is H, i.e., when said variable element 3 reaches the termination of rotation and the load current change signal of said motor 1 exceeds a certain level, the output of said FF 8 is also H and the relay 4 is turned OFF. That is the current path of said motor 1 is cut OFF and the motor 1 stops.

Title: Displacement sensor
Inventor: OKETANI MAKOTO
IPC: G01D5/18
Filed: 1993-03-02
Abstract: PURPOSE:To detect the displacement of an object with high sensitivity by arranging a plurality of magnets, magnetized in nonparallel with the opposing direction of the object, plane symmetrically and arranging Hall elements between the magnets and the object. CONSTITUTION:A Hall element 6 is disposed at a position separated by a predetermined distance from the upper end face of permanent magnets 4, 5 disposed plane symmetrically in a nonmagnetic case 3. When an object to be measured, i.e., a steel wire 7, is placed on the symmetrical plane, flux from N pole to S pole partially passes through the wire 7. When the wire 7 is displaced horizontally, the flux is pulled by the magnetic wire 7 in the direction of displacement whereas it is recovered in the opposite direction. Consequently, flux density at the position of the element 6 decreases as compared with the flux density prior to displacement of the wire 7. Displacement detection sensitivity of sensor is evaluated based on the variation rate of flux density. Since a plurality of magnets magnetized in nonparallel with the opposing direction of the object, flux distribution can be regulated by altering the magnetizing direction of the magnet and detection sensitivity can be enhanced by increasing the variation rate of flux density.

Then, the cylindrical lens 10 is provided in the hole 9 which constitutes the passing space so that its center axis is in the center between said light emitting element 7 and light receiving element 8. Consequently, the light from the light emitting element 7 strikes on a detection surface through the cylindrical lens 10 and its reflected light is projected on the light receiving element 8 through the cylindrical lens 10, so the light emission area and light reception area in the detection surface both become elliptic. Therefore, the light emission area and light reception area overlap with each other more than before and the detection area becomes wide.
