Abstract: PURPOSE:To obtain a high output power semiconductor laser which is excellent in productivity and reliability by a method wherein a second conductivity type impurity is injected from the crystal surface to make the conductivity type of an active layer inverted and to form a stripe-like mesa along a second crystal orientation, and both the sides of the mesa are filled with a second conductivity type light absorbing layer whose forbidden bandwidth is smaller than that of the active layer. CONSTITUTION:An n-type Al0.3Ga0.7As first clad layer 2, an n-type Al0.06Ga0.94As active layer 3, an n-type Al0.3Ga0.7As second clad layer 4, and an n-type GaAs cap layer 5 are made to grow in crystal on an n-type GaAs substrate 1 provided with a (100) plane through an inorganic-metal thermal-decomposition vapor growth method. And, a stripe-like SiO2 mask provided with an opening in, for instance, <011> direction is formed, and Zn is diffused until its diffusing front reaches to the lower end of the active layer 3. At this point, the diffusing front reaches a point inside the second clad layer 4 as deep as 0.7mum, and then the whole face is coated with an SiO2 film and the diffusion is made to continue.

Title: Air-fuel ratio feedback control method for internal combustion engine
Inventor: HIBINO YOSHITAKA
IPC: F02D41/14
Filed: 1987-08-31
Abstract: PURPOSE:To prevent a gap in air-fuel ratio due to aged deterioration of O2 sensor by increasing an integration constant when the change degree of O2 sensor is large in case of feedback controlling the air-fuel ratio according to a deviation between a detection value of O2 sensor and a reference value under proportional-plus-integral control. CONSTITUTION:Detection values of a throttle valve opening sensor 4, an intake air absolute pressure sensor 8, a water temperature sensor 9, an engine speed sensor 10, O2 sensor 13 and so on are input to an electronic control unit 5 to compute and control the valve opening time of a fuel injection valve 6. The electronic control unit 5 feedback controls the air-fuel ratio under the proportional-plus-integral control according to a deviation between a detection value of O2 sensor 13 and a reference value when feedback control conditions within a designated engine speed range are effectuated after the completion of warming-up. At that time, as the change degree of output voltage value of O2 sensor is increased, integration constant is set larger to reduce a gap in the air-fuel ration.

Title: Laser distance measuring instrument
Inventor: YAMADA OSAMU
IPC: G01S17/36
Filed: 1986-09-16
Abstract: PURPOSE:To obtain distance information having no phase detection error by providing a means which corrects a phase shift which is a phase difference according to the intensity of reflected light. CONSTITUTION:Laser light emitted by a laser oscillator 1 is guided to an intensity detector 11 and a phase detector 12. Distance information measured by the phase detector 12 contains an error due to the phase shift corresponding to the intensity of the input signal. For the correction of this error, a correcting value for correcting the phase shift from the previously measured signal intensity is generated by a correcting value generator 13 based on input signal intensity information to the phase detector 12, i.e. intensity information measured by the intensity detector 11 and a phase shift correcting device 14 corrects the distance information by using characteristics of the phase detection error. Thus, a laser distance measuring instrument which irradiates an object with the intensity-modulated laser light to detect the phase difference of the reflected light accurately obtains distance information at a high speed even with a light signal having a wide dynamic range.

Title: Automatic loading system for magnetic tape
Inventor: MARUYAMA TADASHI
IPC: G11B15/67
Filed: 1982-12-13
Abstract: PURPOSE:To determine the direction of a run of a tape for positioning its BOT by detecting the amount of the tape around a take-up reel in muted tape loading operation. CONSTITUTION:In figure, 12 is a photoblock for diameter detection which constitutes a radius sensor together with a reflecting mirror 13 and 14 is a take-up reel motor; and 15 is a diameter detection signal and 16 is an optical signal. When the signal 15 is ''0'' (indicating that the amount of the tape is much) while the tape in a column is taken up, it is judged that the BOT (beginning of tape) is on the take-up reel side, and rewinding operation is started. When the signal 15 is ''1'' (indicating that the amount of the tape is little), it is judged that the BOT is on the payoff reel side, and the tape is fed forward; and the tape is stopped once the BOT is detected within a specific time (required to feed the tape from the beginning to a BOT specifying position), but when the BOT is not detected within the specific time, it is judged that the BOT is closer to the take-up reel side than the photoblock when the tape is taken up from the column, and the rewinding operation is performed.

Title: Load controller
Inventor: KITAGAWA KATSUNORI
IPC: H02J13/00
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent a load from being left on at the time of outgoing, retiring or the like and to conserve power by connecting a plurality of electronic switch masters via signal lines, and attaching a simultaneous OFF means, thereby turning OFF all the loads. SOLUTION: When a simultaneous Off switch 15 is operated, a controller 11 judges the state of switch elements of respective electronic switch masters based on inputs from respective voltage monitors 13. That is, the switch element connected to a signal line of 24 V of a line voltage is judged to be the OFF state, the element connected to a signal line of 47 V of the line voltage is judged to be the ON state, and only the element judged to be ON is turned OFF. For example, in the case that illumination lords of a 'living room' and a 'lavatory' are turned ON and the other illumination loads are OFF, when the switch 15 is operated, individual switches S1, S4 are turned ON by the controller 11. As a result, the load of the 'living room' and the load of the 'lavatory' are turned OFF, and all the loads are turned OFF.

Title: Side straightening control method
Inventor: NAKADA MASATO
IPC: B65H9/20
Filed: 1990-08-21
Abstract: PURPOSE:To shorten throughput by providing two sensors along a contact face, at a space narrower than the length of a medium, and judging the medium to be conveyed normally at the time of both sensors detecting, thereby conveying the medium without performing side straightening action. CONSTITUTION:Along a contact face 3, two sensors 5, 6 are provided at a space narrower than the length of a medium 2. When the conveyance is started and the medium 2 is conveyed into a side straightening position 4, the conveyance is stopped once to recognize the output of the sensors 5, 6. When both sensors 5, 6 are recognized, the medium 2 is judged to have no skew generated, and conveyed as it is into a printing position without being subjected to side straightening action. When only one sensor is recognized, however, the generation of a skew is judged, and the side straightening action is executed and repeated until recognizing both sensors 5, 6. With this constitution, total throughput in a device can be shortened.
