Title: Flaw detector of gear
Inventor: TANIO SHISEI
IPC: G01H17/00
Filed: 1980-05-23
Abstract: PURPOSE:To perform highly accurate flaw detection without being affected by the gain fluctuations of a measuring system by relatively comparing the maximum peak value of the signal filtered out of the vibrations produced by meshing of gears and the average value of the other peak values excluding this. CONSTITUTION:The vibration signal (a) of the gear to be measured which a vibration pickup 1 detects is applied via a charge amplifier 2 and a band-pass filter 3 to a peak holder 4, and only the peak value of the filtered signal (b) is held. The peak value signal (c) is inputted via an AD converter 5 to an arithmetic decision device 7 under the control of the read timing signal (e) branched from the filtered signal (b) and outputted via a read timing detector. In the device 7, the maximum peak value is detected from prescribed pieces of the peak values, and the ratio to the other peak values is compared with a decision reference tau, whereby whether the gear is good or not is decided. Hence, the highly accurate flaw detection is accomplished irrespectively of the fluctuations of the gain of the measuring system.

Title: Distance measuring device
Inventor: MATSUMURA SUSUMU
IPC: G01C3/00
Filed: 1983-04-19
Abstract: PURPOSE:To measure exactly a distance to an object by providing a diffraction grating so as to be insertable and shuntable in a projecting optical system, making a photoelectric converter have at least two kinds of sensitivity characteristics, and switching the photoelectric converter by interlocking with an insertion and a shunt of the diffraction grating. CONSTITUTION:A luminous flux emitted from a light emitting source 3 is diffracted by a diffraction grating 5 through a projection lens 4, and a zero-order diffracted light 8 and + or - primary diffracted lights 9, 10 are generated. A distance measuring spot by three diffracted lights 8-10 is generated on an object (ob) to be photographed, and it scans on the surface of the object to be photographed as the light emitting source 3 rotates. An intensity of the spot light is determined by an uneven quantity of the diffracted grating. Accordingly, by changing the uneven quantity of the diffracted grating, the intensity of the three spots can be made nearly equal, too, and it is also possible to form a shape by which the + or - primary lights are weak and trail to the left and right. When no diffraction grating 5 exists, only an output of A2 is supplied to a signal processing circuit. In this way, an effective photodetecting area of a photodetecting photoelectric converter is switched in accordance with the size of a shape of the projecting spot, and a distance to the object to be photographed can be derived exactly.

Title: Semiconductor laser array
Inventor: HAYASHI NOBUHIKO
IPC: H01S5/00
Filed: 1989-03-20
Abstract: PURPOSE:To convert a laser beam which oscillates at 180 deg. phase mode to a 0 deg. phase mode and emit the same by varying the effective refractive index of a waveguide in an area near a laser emission edge surface. CONSTITUTION:The effective refractive index of a waveguide 14 in an area near a laser emission edge surface 15 of the waveguide 14 is changed every other waveguide 14. If the area of the shaded section having the refractive index changed is denoted as a B area and the white section is denoted as an A area, the wavelength of a laser beam that propagates in the A area differs from that of a laser beam that propagates in the B area. As its frequency varies as the wavelength changes, the phase of a laser beam in the laser emission edge surface 15 deviates from the phase when the B area is not formed in correspondence to the length LB of the B area. The length LB of the B area is set so that this deviation becomes 180 deg.. Thus, even if a laser beam oscillates in the 180 deg. phase mode, since phases deviate 180 deg. every other waveguide 14 because of the B area in the laser emission edge surface 15, the phases of laser beams are aligned to be in the 0 deg. phase mode.
