IPC: H01S5/00
Filed: 1985-04-22
Abstract: PURPOSE:To minimize a nonpoint aberration and avoid a return light noise and reduce a threshold current by a method wherein recessed parts, which are lower than a substrate surface, are provided outside a groove near the surface of a light emitting end and current blocking layers, whose conductive type is opposite to that of the substrate, are provided in stripe shape regions including the recessed parts outside the groove. CONSTITUTION:After recessed parts 2 are formed on a P-type GaAs substrate 1 by etching, N-type GaAs current blocking layers 3 are formed. Then a groove 4 is formed and a cladding layer 5, an activation layer 6, a cladding layer 7 and a cap layer 8 are successively made to grow. Then, after an N-type electrode 9 and a P-type electrode 10 are formed, a reflection plane is formed by cleavage. Therefore, the thicknesses of the cladding layer 5 and the activation layer 6 are different between the outside and the inside of the edges of the groove 4 near the surface of a light emitting end and a large difference of refractive indexes is produced so that a laser beam is confined and a nonpoint aberration is minimized. On the other hand, at the center part, both the cladding layer 5 and the activation layer 6 are thicker and a difference of refractive indexes between inside and outside the edges of the groove is small so that the oscillation spectrum becomes provided with multimode and a return light noise is avoided.

Title: Integrated circuit
Inventor: KAMIYA SHIGEO
IPC: G06F11/24
Filed: 1982-05-20
Abstract: PURPOSE:To detect a fault of an output buffer independently, by connecting selecting circuits provided between an internal logical element and plural output buffers in series and applying outputs trailing stages in a loop, and causing self- oscillational. CONSTITUTION:Plural output buffers 2 (four units in a figure) are connected to the internal logical element through selecting circuits 4. The selecting circuits 4 are connected in series and also input the outputs of trailing stages. The output of the highest-order stage is inputted to the lowest-order selecting circuit to form a loop. When a test terminal 5 is controlled to place the selecting circuits in test mode, the loop circuit enters into a self-oscillation state. If one output buffer 2 is fault, the self-oscillation is not performed. Thus, only the output buffers are checked independently regardless of the internal logical element 1. Further, the delay timer of the output buffer is tested by measuring the frequency of the self-oscillation. This circuit is used suitably for testing an integrated circuit.

Filed: 1992-04-07
Abstract: PURPOSE:To prevent adhesion on the wall face of an intake passage, of fuel injected to the straight port side of an internal combustion engine which includes an intake control valve which generates an intake swirl and allows fuel injection to a swirl port and the straight port. CONSTITUTION:Fuel injection is applied to a swirl port 12a and a straight port 12b from a fuel injection valve 26. A communication passage 27 which allows communication between both ports 12a,12b is provided on a partitioning wall 28 located downstream of the fuel injection valve 26, so that the fuel injection to the straight port side when an intake control valve 32 is closed is atomized by airstream which flows from the swirl port side to the straight port side through the communication passage 27. The fuel injection must be finished before air flow speed becomes excessively large for the purpose of preventing the fuel from adhering on the wall face, but the air flow speed is varied depending on an air leaking quantity at the time of closing the intake control valve 32. Accordingly, the air leaking quantity is determined by a control circuit (ECU) 50 on the basis of the opening of a throttle valve 22, engine speed, an intake air quantity and the like, and a fuel injection timing is adjusted so as to prevent the adhesion of fuel on the wall face.
