Title: Semiconductor laser device
Inventor: KUME MASAHIRO
IPC: H01S5/022
Filed: 1984-06-13
Abstract: PURPOSE:To reduce the induced noise of a returning light by containing 1/2 wavelength plate, rotating the emitted laser light of a package at 90 deg. as a linear polarization, and forming as a linear polarization different from the polarization direction at 180 deg. from the initial when again returning to the package into a laser element. CONSTITUTION:A 1/2 wavelength plate 13 is provided between a semiconductor laser element 14 and an emitting window 12, the linear polarization light is rotated 90 deg. to a circular polarization light, and emitted as a linear polarization from the window 12. Since the laser light returned from the exterior again passes the plate 13, it becomes a linear polarization light rotated at 180 deg. in the polarization direction from the emitting time to the element 14. With this construction, returning light induction noise can be reduced in a light pickup using no light isolator, thereby improving the S/N ratio of a semiconductor laser.

Thereafter, a plunger solenoid 21 is energized. Then, the shaft 18 turns by overcoming the tension of a spring 24 and the surface 18a comes to the position opposite to the end face of the shaft 1a. A torque adder 15 is coupled to a shaft 5, and a shaft 12 is turned at a constant angle by a knob 13 to apply torque upon the object 1 via a coil spring 11, the shaft 5 and the roller 3a, thereby turning the object. In a static state, the rotating displacement angle of the shaft 5 is read with a rotating displacement angle detecting means 9, and torque T is easily calculated from the change in the torsional angle of the coil spring 11 and the rotating angle theta of the object 1 from the ratio between the diameter of the roller 3a and the diameter of the shaft 1a of the object 1.

IPC: B01F15/02
Filed: 1977-10-06
Abstract: PURPOSE:To increase the mixing efficiency and prevent the occurence of bubbling phenomenon by controlling the powder surface trough balancing the discharge and  intake of materials with no skill as the speed of the carrying device at the discharge  port is controlled. CONSTITUTION:Materials with binder added are taken into a mixing body 1 through a material intake port 1' and mixed with mixing impeller vanes 3 set to a mixing shaft 2. At the same time, the materials are heated till the binder reaches its softening point with the steam injected into the mixing body from nozzles 4 placed  on the mixing body 1, also adding necessary water for forming. Since heating and mixing take place in a certain amount of time, the flow rate is controlled by changing the carriage speed of a carrier 6 such as screw conveyor set under the discharge  port so that the material proceeding speed in a chute 7 is changed, thereby balancing the intake and discharge flow of materials and maintainng the material (powder) surface in the mixing body 1.

Filed: 1993-04-22
Abstract: PURPOSE:To prevent a counter-leakage phenomenon caused by a branching flow component in the overlapping part between a roofing tile end a bin even though the grade of the roof is moderate by forming a draining part having a slanting part inclined downward in the front end part of a head part. CONSTITUTION:An inserting part 15 and a sash 16 are formed respectively on the widthwise left and right parts of a roofing tile 11 longitudinally having a front top part 12, a rear tail part 13 and a center trough part 14. Cut-outs 17, 18 are formed respectively on the inserting part 15 side of the head part 12 and on the bridge 16 side of the tail part 13. Further, a straight line-like or concavely curved draining part 20 incorporating a slant part 27 inclined downward is formed in the front end part 19 of the head part. Accordingly, the flow rate of water on the outer surface of the roofing tile 11 is accelerated, and the water is guided further downward and forward of the roofing tile along the angle of the front end of the draining part 20, and accordingly the branching of water between the inside and outside parts of the tile 11 is reduced. Further, when the water flow rate is high, the stream of water is pushed further forward due to an ejector effect, thereby it is possible to prevent counter-flow toward the inside of the roofing tile.

Title: One way direction clutch
Inventor: NARITA KINZO
IPC: F16D41/07
Filed: 1987-05-18
Abstract: PURPOSE:To reduce wear in the region of high speed revolution, heat generation in the region of low speed revolution and wear of sprag by temporarily shifting the center of gravity in the sprag when a revolutional speed exceeds a predetermined value. CONSTITUTION:A curving surface with a radius of curvature R3 smaller than that of a radius of curvature R2 is formed on the end surface of a sprag 4. The center of gravity G is positioned at the side opposed to a vertex 10 with regard to a segment AO2 and a spring force F1 of a garter spring 9 is applied to the sprag 4. When a revolutional speed increases to make the spring force zero, the spring is vibrated so that the center of gravity is temporarily dispalced. The increase in the revolutional speed in the non-wedging direction of an outer ring 3 reduce the spring force F1 so as to make an wedging in the region of the revolutional speed to zero. As the revolutional speed is subjected to zero, the sprag 4 is vibrated with the idling frictional force and the center of gravity G is shifted on the side to which the spring force F1 is applied so as to be stabilized. Thus, the sprag 4 is separated from an inner ring 2 so that wear is not prevented. On the other hand, the reduction of the revolutional speed increases the spring force F1 so that the moment in the wedging direction is exerted on the sprag 4, thus the wedging being performed. Therefore, it is possible to prevent heat generation and wear of the sprag 4.
