Title: Laser diode
Inventor: HAYASHI SHIGEO
IPC: H01S5/00
Filed: 1992-09-21
Abstract: PURPOSE:To realize laser oscillation of blue green color under pulse current injecting conditions of room temperature by inserting a distorted super lattice layer between a ZnSe layer and a ZnSSe layer having incommensurate lattice thereby suppressing propagation of structural defect, improving crystallinity, and enhancing light emission efficiency. CONSTITUTION:An n-type ZnS0.07Se0.93 layer 2 added with chlorine, an n-type ZnSe-ZnS0.07Se0.07 distorted lattice layer 3 added with chlorine, a ZnSe layer 4 added with chlorine, a Zn0.8Cd0.2Se active layer 5, a p-type ZnSe layer 6 added with nitrogen, a p-type ZnSe-ZnS0.07Se0.93Se distorted super lattice layer 7 added with nitrogen, and a p-type ZnS0.07Se0.93 layer 8 added with nitrogen are formed on an n-type GaAs single crystal substrate 1. When a distorted super lattice is formed in such a manner, structural defect formed in a layer distorted due to incommensurate lattice alters propagating direction at the heterointerface of super lattice or stops propagation thereat. This constitution improves crystallinity of ZnSe waveguide layer to be formed and realizes a highly efficient Esaki diode.

Title: Gas filled container provided with gas leak indication
Inventor: NAGAHATA ARINOBU
IPC: G01M3/36
Filed: 1988-10-05
Abstract: PURPOSE:To detect the leak of gas without ruining reliability to a sealing function by making a part of a filled container a thin film and forming a projecting pressure sensitive surface in a nearly round shape on the part. CONSTITUTION:When the leak of gas occurs in the filled container 21 and the pressure of gas 22 inside the container lowers to a specified set value or below, the pressure sensitive surface 21a can not hold its projecting shape with the energy discharging force of an energy accumulating spring 23 and is inverted to be deformed in a recessed shape. With the deformation, a gas leak indication lever 25 turns counterclockwise. Therefore, whether or not the leak of gas occurs in the filled container 21 can be decided from the displacement of the lever 25. Since sealed spots need not be newly increased in such a case, the indication of the leak of gas can be performed without ruining the ordinary gas sealing function.

Abstract: PROBLEM TO BE SOLVED: To provide a plasma processing device for performing plasma etching and plasma deposition efficiently at high speed. SOLUTION: A plasma processing device has a container having a chamber 20, a magnet 30, and a plasma generator. The generator and the magnet are placed outside the container, and a substrate 26 to be changed is placed inside the chamber. A magnetic field 32 is established almost parallel to the surface of the substrate 26 to insulate a plasma from the surface of the substrate. A radio frequency output is made to propagate from the generator into the chamber, in which a plasma is generated. The plasma is generated particularly between the surface of the substrate 26 and the wall part of the container and inside an ionization section 46. Thus an area 48 in the chamber is defined between the sections, and a plasma of almost uniform density is established.  Further, an electrode 56 may be placed in order to apply a bias voltage directly or capacitatively to the plasma to etch the surface of the substrate 26 with ions or to deposit the ions thereon. The voltage applied to the electrode may generate high-energy neutral particles that are ion-exchanged in order to etch the surface of the substrate.
