Abstract: PURPOSE:To enable a semiconductor laser device to have stable laser oscillation, by providing linear impurity regions parallel to each other and having a type of conductivity opposite to that of a semiconductor layer and of high-resistance buried layers, and further providing linear electrodes parallel to each other so as to be formed on said linear impurity regions and to be contacted therewith. CONSTITUTION:An N-type InGaAsP active layer 8 and an N-type InP clad layer 9 are grown in that order on an N<+> type InP substrate 7. An insulation film of SiO2 is formed and provided with an aperture. Using this insulation film having the aperture as a mask, the structure is etched to form grooves 10 reaching the N<+> type InP substrate 10. N<-> type InP high-resistance layers 10A are buried within the grooves 10 by employing the VPE process. The insulation film of SiO2 used as the mask is removed. An N-type InP layer 11 and another insulation film of SiO2 are formed. The insulation film is patterned to form linear apertures parallel to each other. Be ions are implanted with the insulation film used as a mask to form P<+> type impurity regions 12. P-side electrodes 13 and an N-side electrode 14 are further formed. A semiconductor laser device produced in this manner is allowed to have stable laser oscillation.

Filed: 1989-02-13
Abstract: PURPOSE:To offer the condenser for an optical image processing system which is high in light utilization efficiency by employing simple constitution where a diffraction grating is formed at least part of the internal wall surface of a hollow light guide. CONSTITUTION:The diffraction grating 7 provided on the internal wall surface of the light guide 1 projects incident light at a larger angle than its angle of incidence.

Inventor: MATSUMOTO SATOSHI
IPC: H04Q9/00
Filed: 1997-02-18
Abstract: PROBLEM TO BE SOLVED: To securely and speedily detect a fault of the abnormality reporting device of the remote monitor system. SOLUTION: The remote monitor system wherein a center device 1 and the abnormality reporting device 2 are connected together by a communication line 3 is provided with a specific signal sending-out device 5 which always sends a specific signal out to a disconnection monitor device 42. The disconnection monitor device 42 sends an abnormality signal out to the center device 1 once receiving no specific signal.

This monitor device 6 detects a monitor pulse that the abnormality reporting device 2 outputs to a sensor and stops supplying electric power to the specific signal sending-out device 5 when the monitor pulse is not detected.  Consequently, if the abnormality monitor device gets out of order, no specific signal is sent out of the specific signal sending-out device, so that abnormality can be detected on the center device side.
