Title: Elevator door device
Inventor: KOIZUMI YOSHIHIKO
IPC: B66B13/12
Filed: 1994-11-21
Abstract: PURPOSE: To improve safety, maintainability, and economy by providing a cam having a recessed part which actuates door closing force on a sliding door by own weight of a link mechanism, when the sliding door is tightly closed, and an arc part which displaces a movable member to an engagement position of an engagement element, when the sliding door is fully opened. CONSTITUTION: When a sliding door 4 is fully opened, a roller 5d is supported by a recessed part 12e of a cam 12d and an engagement element 10 is arranged between a movable member 5b and a fixed board 5a with its unheld state. A duplex link mechanism 12 is actuated by dead load in such states that the first link 12a rotates clockwise by setting a pivot connection point with the fixed body 3 as a fulcrum and the second link 12b rotates counterclockwise by setting a contact point between the recessed part 12e of the cam 12 and the roller 5d as a fulcrum so that an energizing force in the door closing direction acts on the sliding door 4 under its fully opened state. In the case of tightly closed, an energizing body 13 is in a compressed state so that door closing force of the sliding door is generated. In the case of fully opened, the energizing body 13 is in a tensile state, door opening force is generated. Elasticity of the energizing body 13 can be thus decreased, when the sliding door is tightly closed and energized in the door opening direction, when it is fully opened.

Title: Semiconductor laser device and manufacture thereof
Inventor: YAGI TETSUYA
IPC: H01S5/00
Filed: 1990-10-23
Abstract: PURPOSE:To suppress the reactive current of a semiconductor laser device to nearly zero so as to improve the reliability of the device by forming an active layer having a disordered region near the side face sections of the active layer on the stripe-like projecting section of the first clad layer and the second clad layer of the second conductivity type on the active layer. CONSTITUTION:A p-Al0.15Ga0.85As active layer 3 having a quantum well structure is provided in the stripe-like projecting section 11 of the first clad layer 2, with the areas of the layer 3 near the side face section of the layer 3 being disordered to become mixed-crystal regions 12, and the second clad layer 4 is formed on the layer 3. When a bias voltage is applied across a p- and n- side electrodes 7 and 8 so that the electrode 7 side can become positive, an electric current does not flow to the region between both electrodes 7 and 8 where an SiO2 insulating film 6 exists, but selectively flows to the stripe-like projecting section 11 only. Even in the projecting section 11, the electric current does not flow to the disorder regions 12, since the diffusion potential at the p-n junction in the regions 12 near the side face sections of the layer 3 is higher than that in the non-disordered region. Therefore, the reliability of this semiconductor laser device can be improved, since the reactive current of the device can be suppressed to nearly zero.

Filed: 1991-10-31
Abstract: PURPOSE:To suppress a rise of a DC voltage to a constant value or less when a motor is reversely rotated by an external force by providing a protecting circuit for turning OFF all switching elements when a reverse rotation of the motor is detected and a speed detected value exceeds a preset reference value. CONSTITUTION:When a fan 7 is reversely rotated by influence of an external wind, a reverse rotation detection signal 39 is input from reverse rotation detecting means 35 to an AND circuit 40. On the other hand, a reverse rotating speed detected value is compared with a reference value of a reverse rotating speed of whether all arms are turned OFF or not by a setter 36 by a comparator 37. As a result of comparison, if the detected value does not exceed the reference value, a signal 38 is not output, and hence a signal 41 is not input to a phase distributor 29, and it is normally operated. Accordingly, switching elements 4UU, 4VU, 4WU of the upper arm are sequentially turned ON at each 120 deg. according to a phase detection signal 21.

Abstract: PURPOSE:To change over to a steady state current system from a feedback control system at the teaching time of a moving position and to move a carriage reciprocating in the vertical direction directly by hand by providing a means for switching the feedback control system and steady state current system. CONSTITUTION:The current value necessary for stopping a movable carriage reciprocating in the vertical direction is stored, this current is fed to a driving circuit 10 from a steady state current system 19 and meanwhile no current is fed from a feedback control system 16 by the action of a changing over switch 20. Accordingly, the vertical direction reciprocating movable carriage is moved by hand directly to the aiming position and the teaching of a positional order is enabled. At this time, the current necessary for supporting the dead weight of the vertical direction reciprocating movable carrier is fed to the driving circuit 10 by the steady state current system 19, so to support the vertical direction reciprocating movable carrier by hand during teaching is unnecessary.
