Title: Buried structure semiconductor laser and manufacture thereof
Inventor: SUGAO SHIGEO
IPC: H01S5/00
Filed: 1985-06-27
Abstract: PURPOSE:To improve the high-speed modulation characteristics, efficiency and reliability by a method wherein the buried layer contains at least one kind of impurity which forms a deep level in the layer, and a spacer containing to impurity is provided between the buried layer and the active region. CONSTITUTION:An undoped spacer layer 15 is provided along the side of a double-hetero structure including an active region 11, a P clad layer 12 and a portion of an N buffer layer 13, and when energization is applied to the P side electrode 18 and the N side electrode 19, the current is constricted into the active region 11 because of the function of a high-resistance current blocking layer 14 and a SiO2 layer 17 blocking the current. Since the P-N junction is formed only in the region integrating the active region 11 and the undoped spacer layer 15, the parasitic capacitance reduces, enabling high-speed modulation. Moreover, since the undoped spacer layer 15 is thin, the leakage current flowing while bypassing the active region 11 is small, providing high-efficiency oscillation. Further, since the contamination of the active region by the impurity in the high-resistance current blocking layer 14 is prevented by the undoped spacer layer, the active region does not deteriorate, providing high reliability.

Abstract: PURPOSE:To improve simultaneity of a flaw detecting signal and precision of flaw detection, by a method wherein a magnetic field, which absolute method detecting coils emanate, is utilized for differential method detecting coils, and a dummy coil, shielded with a metal ring, is connected to the absolute method detecting coil. CONSTITUTION:Absolute detecting coils 4, 25 and differential coils 2, 3 are coaxially located at a probe 1. The absolute detecting coil 4 is positioned in the proximity of the middle of the differential detecting ciols 2 and 3, and the absolute coil (dummy coil) 25 is placed at a position allowing it to be spaced enoughly away from the detecting coils 2, 3, and 4 and is shielded with a metal ring 26. As a result, a magnetic field, which the detecting coil emanates, does not reach a wall of a pipe 6 to be measured. If the probe 1 is inserted into a pipe 6 to be measured, the differential detecting coils 2 and 3 are influenced by the magnetic field, which the absolute detecting coils emanate, to detect a flaw detecting signal, and thereby the signals, transmitted by an absolute method and a differential method, are obtained simultaneously. Additionally, the change in temperture and an electrostatic capacity, can be removed, because an absolute detect coil (dummy coil) 25 is provided in the coil of the absolute detecting coil.

Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent such an error as the unattachment of an adjusting fixture, at the time of making a high-voltage output adjustment, at a low cost by permitting the high-voltage output adjustment, only when the removal of a developing unit to be detected by a developing nit presence/absence signal and the attachment of an adjusting fixture unit to be detected by a drum surface temperature signal are detected. SOLUTION: When a printer CPU 110 is connected to the adjusting fixture unit, the printer CPU 110 recognizes that the developing unit 46 is not connected. Further, a thermistor 46a for detecting the surface temp. of a photoreceptor drum outputs a signal changed according to the temperature value of the photoreceptor drum and judges that the adjusting fixture unit is connected to a connector, when the signal is a voltage of 0V, to permit the high-voltage output adjustment. When a supplied signal is a voltage of +1.2V-+3.8V, it is judged that there is a possibility that the developing unit 46 is connected, not to permit the high-voltage output adjustment.
