Title: Semiconductor laser device
Inventor: KUMABE HISAO
IPC: H01S5/00
Filed: 1981-08-31
Abstract: PURPOSE:To stabilize high output operation by forming the crank structure at both ends of a resonator in a thicknesswise direction of a semiconductor substrate. CONSTITUTION:An N type AlxGax-1As active layer 3a is bent toward the thicknesswise direction of a substrate in the vicinity of the end surface 10 of the substrate to form a crank part 12. The region in which a current contributing to the laser oscillation is injected is a straight part 14, and the light emitted here is propagated from the crank part 12 to the end surface 10 through AlyGay-1As second clad layer 4a, thereby amplifying and oscillating. Since the clad layer has larger forbidden band width than the AlxGax-1As active layer 3a (y>x), the absorption of the propagated light through the crank part 12 is reduced that much. The difference of the energy gap between the AlyGay-1As second clad layer 4a and the AlxGax-1As active layer 3a is 400-500meV, and when the  optical path length of the crank part 12 is shorter, the light absorption can be  effectively reduced.

Title: Picture signal receiving circuit
Inventor: TAKAHASHI MASAAKI
IPC: H04N7/16
Filed: 1987-05-30
Abstract: PURPOSE:To prevent the deadlock of an AGC loop when an excessive optical signal is inputted at the time of the input of a silence signal by providing a pilot extracting preamplifier on the output of a photodetector and executing an AGC operation to the photodetector and an automatic gain control amplifier (AGC) by the extracted pilot signal. CONSTITUTION:The pilot signal extracting preamplifier 3 for extracting and amplifying the pilot signal superimposed on the output of the photodetector 1 is provided to execute the AGC by the extracted pilot signal. A pilot signal level is lower by 10dB-20dB than the picture signal level of a main signal. Further, the pilot signal has a frequency completely separate from the picture signal. Thereby, even at the time of inputting the excessive optical signal from the state of the absence of an optical input, the signal is not dissipated even though the output of the pilot signal extracting preamplifier 3 is distorted but the pilot signal can be constantly detected and the AGC operation is maintained in this case to prevent the deadlock of the AGC loop.

Abstract: PURPOSE:To press locally an insulating film into a base metal and to reduce the iron loss of a silicon steel sheet by irradiating a finish-annealed grain oriented silicon steel sheet having an insulating film with at least two electron beams dissimilar in acceleration energy along the width direction of this steel sheet. CONSTITUTION:After finish annealing is applied to a grain oriented silicon steel sheet, e.g., a forsterite film h2 is formed on the above steel sheet and also an insulating film h1 is further formed on the above. Subsequently, the resulting coated steel sheet is irradiated with an electron beam A which has high voltage and small electric current and also has relatively narrow beam diameter and penetrates deeply into the steel sheet, by which local and recessed minute melted regions are formed in the interface between the film and the base metal and simultaneously the film is pressed into these regions to fractionize a magnetic domain. Then, the above sheet is irradiated with an electron beam B of low voltage and small electric current, by which strain in the forsterite film or the insulating film can be released and deterioration in magnetic properties due to the presence of strain can be avoided, and further, iron loss can be advantageously reduced.
