Abstract: PURPOSE:To improve integration density by blocking reactive current by using a semi-insulation semiconductor layer as the semiconductor layer which decides the division of a current passage to the light emitting region. CONSTITUTION:The semi-insulation InP layer 12 doped with chrome by vapor growing method is grown on an N type InP substrate 11.

Abstract: PURPOSE:To make the photocharacteristic of a molded product to be excellent, removing its residual stress-fracture, warpage and deformation by a method in which the incline of the inner pressure of a mold in the flow direction of a molded product before the process of mold clamping/compressing, is omitted, and the mold clamping/compressing is further precisely multistage-controlled. CONSTITUTION:To equalize the amount of injected resin of every shot when the inner pressure Pa of a mold (near a gate) obtained by a sensor 16a reaches injecting compressive pressure P1 (filling pressure in the mold plus compressive pressure) having been preliminarily set, a screw 1 is retreated and the inner pressure is reduced to P2 from P1. After that, the inner pressure Pa of the mold is regulated to P3 by the fine advance and retreat of the screw correspondingly to the change of the inner pressure Pb (the end of resin blow) of the mold obtained by the sensor 16. Its regulation time is controlled with the fine regulation timer t2 for pressure reducing constant. Then, the process is advanced to the compression caused by mold clamping pressure, and the detected inner pressure Pa of the mold is compared with preliminarily set values P4, P5, P6, thereby operating the control mechanism 20 for mold clamping, and controlling the mold clamping process by a closed loop.

Filed: 1990-06-18
Abstract: PURPOSE:To prevent a remote side from being a state that loop forming cannot be restored by allowing the remote side to apply loop control depending on the presence of a remote loop test signal. CONSTITUTION:When a test control signal at a local side is set, a transmission changeover circuit and a reception changeover circuit are switched, a transmission data signal is a remote loop test signal, and a reception data is inputted to a bit error discrimination circuit.

The remote loop is released by resetting a test control signal to stop the transmission of the remote loop test signal. When the remote side cannot detect the remote loop test signal, the remote side releases the loop.
