IPC: H01S3/093
Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To provide an optical semiconductor device which can reduce its threshold value and can improve its high-temperature operational characteristics. SOLUTION: In the optical semiconductor device, an active region 20 having a laser active layer 3 and an inactive region 21 having an inactive MFC layer are sequentially formed along a major surface of a substrate 1. The optical semiconductor device is also formed with a mesa stripe 22. At the time of forming buried layers 7 and 8 of the mesa stripe 22, the buried layers 7 and 8 are formed only on sides of the mesa stripe 22 in the active region 20, whereas, the buried layers are formed, in addition to the sides of the mesa stripe 22, even on an upper side of the stripe in the inactive region 21. Semiconductor laminated layers including the buried layers 7 and 8 form a current blocking structure of a p-n-p-n junction type, whereby, in the inactive region 21, a current can be prevented from flowing through the NFC layer.  Thus a current efficiency as a laser can be improved and its threshold can be decreased.

Title: Magnetic tape end detector
Inventor: SASAKI SHIGERU
IPC: G11B15/05
Filed: 1986-02-19
Abstract: PURPOSE:To reverse tape running as soon as a magnetic tape end comes to a head without being affected by external light by using a head to detect a level difference of hiss noise between a magnetic tape and a leader tape part to discriminate the end of the magnetic tape. CONSTITUTION:A hiss noise detection section uses a high-pass filter 5 to extract the hiss noise component only and when the hiss noise exceeds a prescribed level, an output of a comparator 6 goes to a high level and a low level is outputted when the noise level is a prescribed level or below. That is, when the magnetic tape is running, since the hiss noise level is high, the output of the comparator 6 goes to a high level, a transistor (TR) 7 is turned off, a plunger 8 is not operated and the tape running direction is continued. When the leader tape or cleaning tape is running, the output of the comparator 6 goes to a low level and the TR 7 is turned on. Thus, the plunger 8 is operated, the tape running is inverted to attain quick reversing.

IPC: G01B9/02
Filed: 1993-01-29
Abstract: PURPOSE: To simplify calibration and adjustment by subjecting a light beam generated from a light source to luminance modulation, thereby obtaining a reflectance measurement signal unaffected by polarization. CONSTITUTION: A light from an LED light source 1 is split through a 3dB power splitter 3 to optical fibers 4, 5 for reference arm and test arm. At the time of measurement, the splitter 3 couples the reflected lights from the optical fibers 4, 5 and delivers the coupled light to a polarization diversity receiver 12. Output from an envelop detector 18V or 18H is connected with a microprocessor 19, where the reflectance is determined. Means for modulating the luminance of the light source 1 and a polarization controller PC are built in for the purpose of calibration. During the luminance modulation of the light source 1, imbalance in gain is detected between the two channels V, H of the receiver 12.  Polarized state of the light returning from a reference beam path 4 is limited within a predetermined range by connected a light absorber with the test arm 5 and balancing the channels V, H using the polarization controller PC.

Filed: 1984-02-28
Abstract: PURPOSE:To obtain an inexpensive controller by reducing the current capacity of a thyristor of a regenerative converter smaller than that of the thyristor of the converter, thereby economically using an expensive thyristor. CONSTITUTION:When the effective value of the DC current from a converter 1 at the power drive time is represented by IA and the effective value of the DC current from an inverter 3 at the regenerative operation time is represented by IB, a relationship of IA>IB is valid in case of an elevator system. Accordingly, the current capacities of thyristors 4a-4f of a regenerative converter 4 are selected to smaller one as compared with that of a thyristor of the converter 1, thereby forming a regenerative converter. Thus, an expensive thyristor can be economically used, thereby obtaining an elevator controller having inexpensive regenerative function.
