Title: Driving device for washing machine
Inventor: OSUGI HIROSHI
IPC: D06F37/40
Filed: 1989-09-18
Abstract: PURPOSE:To reduce difference between the static torque and dynamic torque of a brake and to reduce a sliding tone as well when the brake is operated by changing the quality of a lining from synthetic resin to oil-containing colk and applying grease including molybdenum disulfide to the surface of the lining. CONSTITUTION:An attenuator is equipped with a groove part and the width of the groove is formed so as to be slightly smaller than the line diameter of a coil spring 105 and further to be matched with the shape of a hook part. A brake panel 114 is equipped with colk sheet-made linings 115 to be integral by adhesion, etc., on the both side of an outer periphery and bosses 116 are idly fitted in an idle fitting part 117. The brake panel 114 gets contact with a brake attenuator 118 and a lower case 121 with pressure by the brake attenuator 118, brake oscillator spring 119 and volt 120 for spring. Then, the surface of the lining 115 is engraved while including oil and further the grease including the molybdenum dislufide is applied further. The grease generates the stable brake torque and prevents a foreign tone such as a ringing tone, etc., when the lining 115 is slid.

Title: Semiconductor optical element
Inventor: TOKUDA YASUKI
IPC: H01S5/042
Filed: 1988-09-26
Abstract: PURPOSE:To change an effective refraction factor and internal loss and to enable change of oscillation wavelength and oscillation position by forming a plurality of gain waveguide paths close to each other and by changing a current to supply to each electrode. CONSTITUTION:An example of distribution feedback gain waveguide laser having three stripe electrodes is taken. Currents supplied to the three electrodes 1 are named I1, I2, and I3, respectively. Since these upper electrodes 1 are formed close to each other and the waveguide path is a gain waveguide type, a current I2 is injected to a middle electrode 1 at first for laser oscillation. An effective waveguide path width can be changed by injecting a current to electrodes I1 and I3 on the right and the left of the middle electrode I. Therefore, oscillation wavelength can be changed by thus changing an effective refraction factor and an oscillator loss. A light emission position can be made under the electrode I2 by letting I1=I3 and can be deflected right and left from the center by changing the size of I1 and I3.

IPC: H02P25/08
Filed: 1999-08-26
Abstract: PROBLEM TO BE SOLVED: To enhance efficiency of power consumption by suppressing overhead and noise of a motor drive due to chopping conduction thereby driving a motor smoothly. SOLUTION: First and second switches are connected with the opposite ends of a motor coil and a signal for designating chopping conduction of the coil is generated based on a target torque Trq and a motor speed Nm. A chopping frequency fc is set at F1=7.5 Khz when the speed Nm is in region E lower than a low level w1 and at F0=15 Khz when w1 is exceeded. In regions Ab, Cb where the target torque Trq exceeds an intermediate value t1, soft chopping is performed to turn one switch on/off and to turn on the other switch continuously. In regions Aa, Ca where the target torque Trq is equal to or lower than t1, forced soft chopping is performed to delay switching to on/off chopping by 1 μs. In regions Ac, Cc where the speed Nm exceeds w2, 0V loop soft chopping is performed to terminate on/off chopping a little before the end of phase conduction period.

Filed: 1984-11-15
Abstract: A movable and a stationary contact element are tubularly structured for the purpose of axially discharging arc gases. A blast nozzle is associated in a fixed reference position with respect to one of the contact elements. A narrowest location or throat of the blast nozzle is positioned forwardly of the end of this one contact element and is closed by the other contact element in the cut-on position of the gas-blast switch. An inlet of the blast nozzle communicates with a pump space bounded by a cylinder and a piston. The contact element with which the blast nozzle is associated displaceably extends through the piston. The pump space can be pressurized during a cut-off stroke. Both of the contact elements are provided with related outlets in their related regions which are remote from the free ends of the contact elements. At least in the cut-off position the outlets interconnect an interior space formed in the related contact element and a blow-out space. In order to utilize the pressure pulses occurring due to a switching arc, for supporting the pressure prevailing in the pump space, the outlet of the contact element, with which the blast nozzle is associated, opens into the pump space in the cut-on position and the distance of this outlet from the free end of the related contact element is greater than the pumping stroke between the piston and the cylinder which occurs during the cut-off stroke.
