Title: Semiconductor laser array device
Inventor: HAMADA TAKESHI
IPC: H01S5/00
Filed: 1983-11-08
Abstract: PURPOSE:To obtain two different wavelengths through the same manufacture as a normal device by forming each layer containing an active layer on a substrate, to which a stepped section and a groove are shaped, and each forming current injection regions to the stepped section and the groove section. CONSTITUTION:A stepped section 1a is formed on the surface of a substrate 1, and a groove 1b is shaped to a substrate flat section on the lower side of the stepped section. An n type clad layer 2, an active layer 3, a p type clad layer 4 and an n type cap layer 4 are grown continuously on the substrate 1. A p type impurity is diffused selectively to a section just above the folding section of the layer 3 formed by the stepped section 1a on the substrate and a section just above the groove section 1b in a striped shape from the surface grown, and made to reach to the layer 4. When currents are injected so as to drive a laser C formed to the stepped section in such constitution, beams generated in the layers 3, 3 are confined in the folding section of the layer 3, and an oscillation is generated in the folding section. When currents are injected so as to drive a laser D formed to the groove section 1b, on the other hand, beams generated in the layer 3 are confined in the groove section. The oscillating wavelength of the laser C is made longer than that of the laser D.

Title: Displacement sensor
Inventor: TANIGUCHI YOSHIHISA
IPC: G01B11/00
Filed: 1993-07-30
Abstract: PURPOSE:To detect the absolute value of a displacement amount having a multi-degree of freedom by providing a light receiving means for outputting a signal corresponding to the incident position of an optical beam, and an arithmetic means for finding the displacement of the light receiving means from an illuminant on the basis of the output. CONSTITUTION:An illuminant (semiconductor laser) 1 is fixed to a base, while a light receiving means (two-dimensional CCD) 4 is mounted on a travel body. In this case, when an optical beam 2 from the illuminant 1 is incident on the light receiving means 4, a cell address corresponding the incident position thereof is outputted. Also, with the motion of the travel body, the output cell address changes, depending upon the incident position of the beam 2. Furthermore, an arithmetic means (microprocessor) can obtain the displacement of the travel body from a difference between new and old addresses. In addition, the angle of rotation (angular displacement) of the travel body can be obtained from the direction of the vector thereof by subtracting the address of the incident point A of the beam 2 from the address of the incident point B of another optical beam 3 emitted from the illuminant 1. Thus, the displacement of three degrees of freedom for rotation about X- and Y-axis directions can be detected with a single displacement sensor in non-contact state.

Filed: 1988-08-23
Abstract: PURPOSE:To positively prevent an automobile from being stolen by bringing the seat back of a driver's seat down forward when the seat is detected to have been unattended and when doors are detected to have been locked, and thereby constituting the seat that it can be locked in a brought down forward condition. CONSTITUTION:When a driver gets off an automobile and when doors are closed, firstly a seat switch 41 detects that a seat 1 has been unattended so as to output a signal, and secondly a door lock detecting switch 51 detects that the doors have been locked so as to output another signal. Then, a control device 60 allows actuating signals to be outputted after time more than a specified one (roughly 10 seconds) has elapsed since both of the signals have been inputted. The actuating signals allow a clutch type motor 12 to be operated so as to let both a holding member 9 and a locking member 10 which are meshed with a pinion 33 be moved downward. This permits both engagement between a pawl section 26 and an engaging section 18 and engagement between a pawl section 29 and a segment gear 14 to be released so that a seat back 3 is brought down forward, which situation permits the pawl section of a cylinder lock 34 to be engaged with a locking piece 15 so as to be locked.
