IPC: H01M4/26
Filed: 1997-10-29
Abstract: PROBLEM TO BE SOLVED: To activate a Zr-Ni Laves phase hydrogen storage alloy so as to enhance the alloy capacity of a hydrogen storage alloy electrode. SOLUTION: A hydrogen storage alloy is hydrogenated by heating in a hot atmosphere of hydrogen and rapidly cooling immediately after the heating and then degassing is carried out by evacuation to highly activate the hydrogen storage alloy. It is preferable that the activated hydrogen storage alloy is heated in a KOH soln. after dipping in a soln. of HF and NH4 F.HF to which an Ni salt is optionally added. Activation frequency in initial activation is considerably reduced and the alloy capacity of a hydrogen storage alloy electrode can be enhanced.

IPC: H03K17/66
Filed: 1994-11-30
Abstract: PURPOSE: To provide a driver circuit for signal transmission without using an element with high allowable dissipation and in which power consumption can be reduced. CONSTITUTION: Output transistors Q1 , Q2 are connected complementarily, and connected between both terminals of a power source. The bases of both output transistors Q1 , Q2 are commonly connected, and a transistor Q6 for driving is inserted between the positive electrode of the power source.

Title: Moving field type dc motor
Inventor: NOMURA TAKASHI
IPC: H02K23/62
Filed: 1990-11-05
Abstract: PURPOSE:To obtain an easy-to-start moving field DC motor having simple structure by providing an annular stator producing N and S poles alternately and a rotor comprising permanent magnets having polarities corresponding to the N and S poles of the stator and then switching the N and S poles in synchronism with the rotation of the rotary shaft of the rotor. CONSTITUTION:When a switch SW 23 is turned ON to excite a stator 10, the stator 10 produces N and S poles substantially identical to the N and S poles of a permanent magnet 3. Since a shading ring coil 6 is provided, combined flux has phase delay and the N and S poles of the stator 10 have phase shift, corresponding to the flux produced from the shading ring coil 6, from the N and S poles of the permanent magnet 3. Consequently, the permanent magnet 3 mounted on the rotor 2 on a rotary shaft 1 is subjected to repulsion and rotates. The rotor 10 is thereby switched, in synchronism with the rotation of the rotary shaft 1, by means of a slip ring 21 and a brush 24 and the permanent magnet 3 is provided continuously with toray torque thus sustaining the rotation. According to the constitution, the motor can be started easily and the structure thereof is simplified.

Filed: 1985-12-28
Abstract: PURPOSE:To transport a photographic paper stably without applying an excessive force to it and to prevent the degradation in processing capability by forming plural printed pictures on both sides in a lateral direction on the long- sized photographic paper while leaving a blank part and using the blank part as a guide part for transportation. CONSTITUTION:A focusing lens 133 is placed in a position L1 of a turret type holding frame 132 to form a printed picture on a left area P1 in the lateral direction of the photographic paper, and the lens is moved to a position L2 to form a printed picture on an area P2, and the photographic paper is transported by an extent corresponding to one frame and pictures are printed by the lens in positions L2 and L1, and this operation is repeated. The excessive force is not applied to the photographic paper because the transporting speed can be make lower than that in the process where pictures are printed in a row in the longitudinal direction of the photographic paper, and the pictures are not damaged because both ends of the photographic paper are guided by guides 51 and 52 and the blank part between printing area is guided by a U-shaped guide 53. Thus, the photographic paper is transported stably without degrading the processing capability.

Abstract: PURPOSE:To prevent the attenuation of information light by using coherent light for the transmission and exchange of light information and providing an exchange control section which modulates the light to the polarization angle allotted to an outgoing part of the address in an incoming part. CONSTITUTION:Polarization angle modulating means 10, 11 of the incoming part 1 set the modulation and polarization angle in conformity with the angles desired by polarization filter means 20, 21 provided in the outgoing part 2 by the control of the exchange control section 3. The setting of the polarization angle is executed by using a Faraday effect if the polarization angle modulation means 10, 11 use transmitted light and by adapting a Kerr effect if the means use reflected light. The modulation means 10, 11 modulate plane 400 of polarization of the incident information light to the modulation angle 405 when the set angles of the polarization filtering means 20, 21 of the outgoing lines 5, 6 are 205 and 206 and select the formation of a channel to the outgoing line 5 and modulate the polarization angle to the modulation angle 406 when the outgoing line 6 is selected. The information light of the incident plane 400 of polarization to the incoming line 4 is modulated and propagated to the plane 405 of polarization, by which the light is selectively transmitted by the polarization filtering means 21 and is emitted to the outgoing line 5. The channel 7 from the incoming line 4 to the outgoing line 5 is formed in this way.
