Title: Braking circuit for induction motor
Inventor: IWATA MASAHIKO
IPC: H02P3/24
Filed: 1980-06-26
Abstract: PURPOSE:To apply a DC braking without damage to an induction motor with a simple circuitry by stopping a basic clock of an inverter when a DC voltage lowers down to the level the same as the braking voltage applied to a converter at braking. CONSTITUTION:When an input ''1'' is applied to a control terminal C as braking command, the output of a comparator 19 is ''0'' while DC power supply voltage VP is higher than voltage braking voltage VB. A voltage adjustor 3 sends the voltage VB and the torque of an induction motor 10 with a gradual drop of the voltage VP. When VP=VB, the output of a comparator 19 goes to ''1'' while the output of an AND gate 11 to ''1''. Consequently, the input of a ramp wave generator 13 moves to ''0'' and the application of the oscillation frequency to a ring counter 17 is stopped. Therefore, an inverter 2 is stopped at any one of six driving modes and a DC voltage is applied to a stator winding of the induction motor 10 as an exciting voltage at a lower level that the DC power supply voltage at the normal time.

IPC: B60G7/00
Filed: 1982-05-22
Abstract: PURPOSE:To remove lack of stability of damping characteristic due to an inflow of bubbles by forming a plurality of pocket portions in which an incompresible fluid is enclosed, which communicate one another through holes mounted on the inner cylinder metal. CONSTITUTION:An incompresible fluid is enclosed in two concabe portions 18 of a rubber sleeve 8, and the fluids communicate each other through a hole portion 22 of a metal sleeve 6 and a peripheral groove 24 of the outer periphery of an inner cylinder metal 4. When gas penetrates into the concave portion 18 or is generated therein, the gas stays in the outer peripheral portion of the concave portion 18. Therefore, it is not feared that air bubbles flow into the hole portion 22 and the groove 24 so as to provide a stable damping characteristic.

Title: Optical waveguide integrated semiconductor laser and manufacture thereof
Inventor: IWANO HIDEAKI
IPC: H01S5/00
Filed: 1988-04-08
Abstract: PURPOSE:To obtain a current-controlled continuously adjustable beam spot by forming, on the end surface of one resonator of a semiconductor laser, a semiconductor optical waveguide region having an energy gap greater than that in an activated layer region and using a II-VI compound semiconductor to bill in a contact layer of the optical waveguide region along an optical resonator. CONSTITUTION:An optical waveguide integrated semiconductor laser comprises a semiconductor laser section 101 and an optical waveguide section 102. An activated layer 112 of the semiconductor laser section and an optical waveguide layer 113 of the optical waveguide section are formed on the same plane. The semiconductor laser has a smaller Al composition ratio than the optical waveguide layer and a greater energy gap than GaAlAs of the activated layer. A contact layer 108 is left in stripe form in the semiconductor laser section 101, while it is removed in stripe form on the optical waveguide section 102. The removed part is filled with a II-VI compound semiconductor such as ZnSe, on which electrodes 111, 110 are formed. As implantation currents 115, 114 are independently supplied thereto respectively, carriers are fed into the activated layer to cause optical amplification and to oscillate laser at a spot. Accordingly, a current control allows the spot diameter of semiconductor laser to be arbitrarily adjusted.

Abstract: PURPOSE:To facilitate the high speed switching and enable integrating elements, by compounding a semiconductor layer from an organic thin film composed of pi-conjugated polymer and equipping a gate electrode only at the part opposing the part where said semiconductor layer is put between a source electrode and the drain electrode. CONSTITUTION:A semiconductor layer 4 is made of an organic thin film composed of pi-conjugated polymer and a gate electrode 2 is formed only at the part opposing the part where said semiconductor layer is put between a source electrode 5 and a drain electrode 6. pi-conjugated polymer having a heterocyclic five-membered ring is desirable for forming the organic thin film 4 because it fits the characteristic of an FET, has high ability to form a film, and is easy to synthesize; however, any other pi-conjugated polymer is acceptable. This reduces the capacitance between the source and the gate and between the drain and the gate, increases the current switching speed, and enables integrating elements.
