Title: Semiconductor laser device
Inventor: YAMAZOE YOSHIMITSU
IPC: H01S5/026
Filed: 1982-06-23
Abstract: PURPOSE:To effectively pick out a laser beam by a method wherein the light reflecting end face or the projecting end face of the beam of light of the semiconductor laser device is formed into curved surface. CONSTITUTION:An N-clad layer 6, an active layer 5, a P-clad layer 4 and a junction layer 3 are stacked on a substrate 7, and after a groove has been provided on an insulating film 2, both end faces are shaped into cylindrical curved surface by performing an etching. The axis of a cylinder is vertical to the substrate, and the center of a circlar arc 21 is located above the center line 18 of the active layer. Through these procedures, a pick-out end face 11 and a reflection end face 11a are formed, and then an electrode 1, a lead connection part 17 and an electrode 9 are provided. The width of the curved surfaces 11 and 11a is to be made wider than the beam width. When both end faces are curved, the reflection surface of laser is turned to a concave mirror, beam width is widened in the vicinity of a pick-out end face, thereby enabling to reduce the deterioration of the end face, also light is focussed in the center part of the semiconductor, and an oscillation threshold value is reduced. Besides, light is focussed at the desired point outside the element, thereby enabling to perform an easy coupling with an external photo circuit. Also, an advantage in stabilization of the device is obtained when the end face 11 is maintained in a plane state.

Abstract: PURPOSE:To enable supply or small distribution to a container to be carried out by suspending and supporting a bag-shaped container within the wide-opened part in the upper part of a supplier, and moving a contained material into the supplier through its self-weight in releasing the closure of the container port. CONSTITUTION:A bag-shaped container 20 contained with a material 40 is suspended in putting the closed mouth part 21 down, and then the mouth part 21 of the container 20 is released from closure. As the material within the container 20 comes down through its self-weight, the mouth part 21 of the container is brought into press contact with the inner surface of the wide-opened part of the supplier in its end periphery in close contact therewith. Therefore, the material 40 within the container 20 may not overflow from the wide-opened part 11 of the supplier 10, and comes down and moves into the supplier 10. The material 40 coming down thereinto is supplied in a container such as a hopper 31 or the like by a supplying part 12 through a valve 13 from the wide-opened part 11. At this time, the lower end of the supplying part 12 is placed at a position lower than the mouth part of the hopper 31, so that the material 40 coming out of the supplying part 12 is heaped such that the hopper 31 is filled thereby.

Title: Apparatus for detecting displacement of weight
Inventor: OZAWA HIROMASA
IPC: G01P15/093
Filed: 1985-05-20
Abstract: PURPOSE:To detect the absolute value and direction of acceleration with high accuracy, by providing a wt. to the free end of an optical fiber fixed at one end part thereof and forming a free end at the other end part thereof and receiving light passing through the optical fiber at the free end side by a charge coupling element. CONSTITUTION:One end part of an optical fiber 11 is fixed to the part of a fiber piercing hole 10a and a wt. 12 is mounted to the free end of the other end part of said fiber. Because the optical fiber 11 is always vertically suspended, the light emitted from a light source 13 passes through the optical fiber 11 to be formed into an image on the central part of a charge coupling element 14. However, if acceleration is acted in any direction within a horizontal plane, the wt. 12 is displaced and the optical fiber 11 is also curved to change a position where the light emitted from the optical fiber is incident to the element 14. Therefore, the difference between the central position of the element on which light is incident from the lower end of the optical fiber 11 before acceleration is acted and the position where the light from the optical fiber 11 is incident when acceleration is acted is operated by a control circuit 15 and the absolute value of the magnitude of acceleration and the direction signal of acceleration are outputted from an output circuit 23.
