Title: Wavelength converting element
Inventor: JO CHIYOUSEI
IPC: G02F1/37
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To optically vary the wavelength of signal light and the wavelength of converted light by providing an electrode which has a heating means on a substrate opposite and in parallel to an optical waveguide. SOLUTION: On the top surface of an LiNbO3 substrate 10, domain inversion areas 12 are provided in stripes. On the top surface of the LiNbO3 substrate 10, the optical waveguide 14 is provided crossing the domain inversion areas 12. On the top surface of the LiNbO3 substrate 10, heat electrodes 16 having heating means are provided on both the sides of the optical waveguide 14 at intervals with the optical waveguide 14. Then the heat electrode 16 consists of a heat electrode main part 16a for heating the area of the optical waveguide 14 and heat electrode end parts 16b and 16c for applying a voltage. At this time, the heat electrode 16 is provided in parallel to the optical waveguide 14 so as to uniformly heat the area of the optical waveguide 14.  Thus, the optical waveguide 14 can be heated by applying the voltage between the heat electrodes 16, so the refractive index of the area of the optical waveguide 14 can be varied.

Title: Control device for automatically opened/shut door
Inventor: FUJII TAKANARI
IPC: E05F15/60
Filed: 1992-02-28
Abstract: PURPOSE:To construct small a control device for an automatic opening/shutting door and make a wire harness protected, by using a multi-phase brushless DC linear motor for driving a door, and sensing the door/moving piece position, direction, and speed with a multi-phase magnetic sensor. CONSTITUTION:A door 2 is coupled with the moving piece 7 of a multi-phase brushless DC linear motor to esteblish the direct drive system. For driving the moving piece 7, a multi-phase magnetic sensor senses the relative position, direction, and speed of a door 2 to the moving piece 7 with inversion of the regular/reverse moving direction of the moving piece 7. One end of a wire harness 1 including feeder cable and signal line is connected with the moving side moving piece 7 while the other end is connected with a stationary side control circuit 8. The difference obtained by subtracting the number of pulses in which the thickness of the wire harness 1 is taken into account, from the door 2 open position is stored and controlled. This allows omitting provision of any speed reducer, belt, particular sensor, etc., to lead to simplification of the structure and permits preventing the harness 1 from being pinched by the door 2 and the open-side pillar.

Abstract: PURPOSE:To decrease the occupied area of both capacitors by providing an adjusting circuit adjusting a voltage applied to a capacitor for extracting a charge so as to be smaller at all times than a voltage applied to a capacitor for storing a charge. CONSTITUTION:A potential V1 of a node 5 is expressed approximately in Equation I, where gm<1>, gm<2> are conductances of transistors (TRs) 7, 11 and K is a back bias effect coefficient of the TR11.

The charge stored in a capacitor 1 is discharged gradually by repeating the operation above. The potential of the node 8 is adjusted so as to be decreased automatically in response to the decrease in the potential of the node 5 and the voltage fed to the capacitor 2 is kept always smaller than the voltage fed to the capacitor 1.

Title: Equipment and method for constant voltage power supply
Inventor: TANIGUCHI TERUYUKI
IPC: H02M3/155
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain required output voltage stably by installing a switching- method step-up power circuit having a control circuit in a pre-stage, and installing a dropper-method constant voltage power circuit or a switching-method step-down power circuit in an after-stage. SOLUTION: A control circuit 2 monitors the output voltage of a switching- method step-up power circuit in a pre-stage by a comparator 3. When the monitored voltage is lower than a specified output voltage for the switching- method step-up power circuit in the pre-stage, the on-state duration is extended to increase energy to be accumulated in a choke coil L1, and the switching- method step-up power circuit is so controlled that the output voltage may be higher than the specified voltage. In the case that the monitored voltage is higher than the specified voltage, the on-state duration is shortened to lessen energy to be accumulated in the choke coil L1, and the switching-method step-up power circuit in the pre-stage is so controlled that the output voltage may become lower. With this method, even when the input voltage varies, required output voltage can be obtained stably.
