Title: Semiconductor light-emitting element
Inventor: NISHI KENICHI
IPC: H01S5/00
Filed: 1986-03-17
Abstract: PURPOSE:To reduce the lowering of luminous efficiency, and to obtain high-speed optical-output modulation characteristics by intentionally doping an impurity only to a semiconductor layer having wide forbidden band-width in semiconductor multilayer structure. CONSTITUTION:An S-doped N-type InP buffer layer 12 in 2mum, a light-emitting section 15 consisting of four cycles of undoped In0.75Ga0.25As0.54P0.46 layers 13 in 200Angstrom  and Zn-doped P-type InP layers 14 in 200Angstrom , a Zn-doped P-type InP clad layer 16 in 2mum, an undoped InP clad layer 17 in 0.5mum are laminated on an S-doped N-type InP substrate 11 in succession.

Title: Optical isolator
Inventor: FUJII YOJI
IPC: G02B27/28
Filed: 1988-03-14
Abstract: PURPOSE:To realize high isolation as to the angle of polarization-directional rotation angle by a Faraday element by arranging a 1st birefringent crystal plate, a two-axis optical crystal plate, the Faraday element, and a 2nd birefringent crystal plate from the forward incidence side of light. CONSTITUTION:A polarizing element which is arranged on the forward incidence side of the optical isolator consists of the birefringent crystal plates 1 and 2 and the two-axis optical crystal plate 5 which is free from characteristic polarization when the light is incident in the direction of the main optical axis. Therefore, when a light beam which is incident on the two-axis optical crystal plate in backward operation is different in polarization direction from a light beam which is projected from the two-axis optical crystal plate at the same position as the incidence position in the backward operation in the forward operation, the backward light beam is never projected from the two-axis optical crystal plate at the same position as the incidence position of the light beam in the forward direction. Consequently, even if the angle of polarization- directional rotation angle of the Faraday element 3 is different from pi/4, the high isolation is obtained.

Title: Method for coating gas permeable porous body with resin
Inventor: TAKAGI NORIO
IPC: B05D3/12
Filed: 1990-03-14
Abstract: PURPOSE:To form a resin film enhanced in bond strength by bringing a part of the surface of a gas permeable porous body into contact with a fluid having a powdery resin dispersed therein to accumulate the powdery resin on the contact surface with the fluid by pressure difference and heating the accumulated film layer to fix the same to the porous body. CONSTITUTION:A part of the surface of a gas permeable porous body is brought into contact with a fluid having a powdery resin (e.g. fluoroplastics) dispersed therein to generate pressure difference between the contact surface with the fluid of the porous body and the other surface thereof. The medium constituting the fluid is allowed to flow from the contact surface with the fluid of the porous body to the other surface thereof by this pressure difference to accumulate the powdery resin on the contact surface with the fluid and the surface layer part thereof. If necessary, drying treatment is applied to the gas permeable porous body to heat the formed accumulated film layer along with the gas permeable porous body and the accumulated film layer is sintered to be fixed to the porous body. By this omitted process, the resin film enhanced in bond strength can be formed to a part of the surface of the air permeable porous body. Further, the thickness of the resin film and the flow resistance of the porous body can be altered to a large extent by the simple alteration of a condition.

IPC: B65G43/00
Filed: 1993-03-22
Abstract: PURPOSE:To securely stop the movement when a suspension plate is operated while pushing containers on the downstream end by arranging a stopper operated together with the stopping plate. CONSTITUTION:In the case of stopping to supply a container, when a cylinder 7 is extended by a stopping signal, a stopping plate 9 is pushed out, and pushes the side surfaces of containers 1 and 1a, and stops the movement. During the time, as an interval between the suspension blate 9 and a stopper fastening metal fitting 15 fixed to the cylinder 7 side becomes wide, a stopper 12 is pushed by a spring 13, and rotates around a pin 12, and the tip (a) is pushed out to the conveyor 3 side. At this time, the tip (a) projects to the conveyor 3 side from the extended surface of the side surface on the conveyor side of a rubber 10 of the stopping plate. Thereby, the tip (a) pushes more quickly the side surface on the downstream end of the conatiner 1a in the forefront, and prevents the container 1a from slopping out from the suspension plate 9. In this way, the movement of the prescribed number of containers 1 and 1a can be stopped reliably in such an improvement as arranging a simple stopper 12.
