Title: Optical circuit device
Inventor: KAWAGUCHI TAKAO
IPC: G02B6/42
Filed: 1984-07-02
Abstract: PURPOSE:To couple optically a semiconductor laser and an optical waveguide efficiently and stably by joining the semiconductor laser and an optical circuit into one body and impressing a voltage to a piezoelectric element to contract and expand the piezoelectric element and generating slide deformation. CONSTITUTION:A semiconductor laser 4 is fixed to the first holding part 2, and a piezoelectric element 5 is put on the second holding part 3, and an optical circuit board 7 where an optical waveguide 6 is formed on the surface is held in the piezoelectric element 5. The piezoelectric element 5 is polarized in the normal direction of the surface of the second holding part 3 by providing electrodes 8. When voltages are impressed to electrodes 8 and 10, the structure indicated by solid lines is changed to the structure indicated by broken lines. When the voltage is impressed to electrodes 10, slide deformation is generated, and therefore, the relative position of the optical waveguide 6 to the semiconductor laser 4 is changed right or left to attain efficient optical coupling.

Title: Ready mixed concrete pressure sending pump
Inventor: KATO SHOGO
IPC: F04B15/02
Filed: 1986-06-13
Abstract: PURPOSE:To prevent occurrence of clog or bite-in by making the tip of a three- way opening/closing valve furnished at the bottom outlet of a hopper for ready mixed concrete in the form of small wall thickness having a curvature, and furnishing a valve seat having a sharp tip at the inner wall surface of valve box and in the neighborhood of the bottom outlet from the hopper. CONSTITUTION:A three-way opening/closing valve 4a reducing its wall thickness gradually toward the tip 4c and having curvatures 4d, 4e is installed on a shaft 4a borne by a valve box 2a. On the other hand, a valve seat 2c with angle- shaped profile having curvatures 2e, 2f with which said tip 4c of three-way opening/closing valve 4a can contact or separate therefrom, is provided at the bottom of this valve box 2a, while another valve seat 17 having a tip 17a with which said curvature 4d of three-way opening/closing valve 4a can contact with a certain angle held, is furnished in the neighborhood of the bottom outlet 1a from the hopper 1. This eliminates risk of biting-in of aggregate in ready mixed concrete when the three-way opening/closing valve 4a is opened or closed, and clogging occurring with it can be prevented.

Title: Charge pump type booster circuit having output voltage stabilizing function
Inventor: SATO YASUSHI
IPC: H02M3/07
Filed: 1993-06-08
Abstract: PURPOSE:To stabilize the output voltage while enhancing the efficiency in voltage regulation by comparing the output from a booster circuit with a reference voltage and varying the ON resistance on one switching transistor depending on an error signal thereby controlling the charging operation. CONSTITUTION:A boosted voltage Vout appearing at the output terminal 105 of a booster circuit is divided by means of resistors R1, R2. A divided voltage V1 is applied to the positive input of a comparator 106 and compared with a reference voltage VR from a reference voltage supply 109. When the voltage V1 is higher than the reference voltage, the comparator 106 outputs a positive error signal to increase the gate bias of a transistor TR5 thus decreasing the drain/source resistance RDS. Consequently, the gate voltage of a transistor TR2 lowers to decrease the ON resistance thus lowering the output voltage Vout. When the voltage V1 drops below the reference voltage, the comparator 106 delivers a negative error signal to lower the gate bias of the TR5 and increase the resistance RDS thus increasing the output voltage Vout. This constitution realizes highly efficient stabilization and regulation of output voltage.

Title: Device for repairing pipe joint of existing pipe
Inventor: HAYASHI MITSUTOSHI
IPC: F16L55/18
Filed: 1984-07-03
Abstract: PURPOSE:To perform secure repair without consuming resin uselessly by applying a flexible covering body for enlarging a part of a dragging wire to large diameter to the external periphery of the dragging wire in a specified range in the front side of a pig. CONSTITUTION:Pigs 2, 3 inserted into an existing pipe 1 through an inserting pipe are drawn by the operation of the dragging wire 4. In this stage, resin C having low viscosity charged to the front side of the front pig 2 diffuses to the inside of the pipe 1 and into dusts incorporated in the space of a pipe joint 13 to improve the lubricity of the internal periphery of the pipe 1 and makes movement of resin D to be filled in the joint and the movement of a hind pig 3 easier. Furthermore, since a cylindrical body 14 is provided to the external periphery of the dragging wire 4 at the front side of the pig 3 in the stage for drawing the pigs 2, 3, the length in the inside of the pipe 1 occupied by the resin D is increased and the viscous resistance is increased and the resin pressure is also increased. Moreover, the time for filling the resin to the joint part is prolonged. Therefore, the filling time to the joint part is prolonged and the repair is performed securely with less consumption of resin.

Accordingly, the pressure intensifying gradient of the brake pressure is sharp so as to reach a designated level quickly. The responsiveness of the accelerating slip control is heightened as shown in (b), and good starting and accelerating performance can be ensured.

Title: Injection molding machine and production of injection-molding product
Inventor: HARADA KOJI
IPC: B29C45/27
Filed: 1995-06-06
Abstract: PURPOSE: To increase the cooling speed of the residual resin in a hot runner nozzle to prevent the thermal deterioration thereof by forming an injection hole allowing an air heat insulating layer to communicate with the outside and injecting a cooling medium and a cooling medium discharge hole to a movable mold. CONSTITUTION: A cooling medium injection hole 11 allowing the air heat insulating layer 3 to communicate with the outside and a cooling medium discharge hole 12 are formed on a movable mold Ma2 . By this constitution, the interior of the air heat insulating layer 3 becomes a cooling medium passage. Therefore, when a cooling medium is sent into the air heat insulating layer from the cooling medium injection hole 11, the cooling medium flows through the passage and a hot runner is cooled as a whole while the cooling range of the cooling medium is gradually widened from the hot runner part in the vicinity of the passage by the flow of the cooling medium. By this constitution, the resin remaining in the a hot runner nozzle 7 is also cooled.  The cooling speed of the residual resin in this case is increased and, therefore, the heat load quantity applied to the resin is reduced and the residual resin is not thermally deteriorated.
