Title: Reflection type diffraction grating for trisecting beam and optical pickup formed by using the same
Inventor: MORI KAZUSHI
IPC: G11B7/135
Filed: 1994-05-09
Abstract: PURPOSE:To form a reflection type diffraction grating for trisecting a beam by condensing the trisected and diffracted beams at symmetrical spot intervals to a small spot in the case of arranging the reflection type diffraction grating for trisecting the beam with a inclination with a light source. CONSTITUTION:This reflection type diffraction grating 11 for trisecting the beam is used by inclining the diffraction grating with the optical axis of the diverging laser beam source and eventually the incident angle of the laser beam varies in the inclination direction on the grating surface. The diffraction grating described above has the effect of diffracting the beam in this inclination direction. The period of the grating is so modulated that the period of the grating is longer on the grating surface 11a as the incident angle of the laser beam is larger within at least the effective aperture. The + or -1st order virtual light sources formed by the trisected diffraction effect are so formed as to be symmetrical with the zero order virtual light source as a center and to be narrow in the width of the light intensity distribution.

Title: Recognition device
Inventor: TAKAGI HIDEYUKI
IPC: G10L15/00
Filed: 1984-05-11
Abstract: PURPOSE:To correct an error in recognition without keying by correcting the error in recognition on the basis of an organism signal. CONSTITUTION:Electrode 50 are fixed at a (+) and a (-) position before recognition, and a voice signal to be recognized, e.g. ''wa'' are sent to a recognition part 1 and matched with standard patterns stored in the recognition part, and pattern characters with higher similarity are sent to a correction part 2 in order. For example, ''a'' as the 1st candidate, ''ha'' as the 2nd candidate, ''wa'' as the 3rd candidate, and ''ta'' as the 4th candidate are obtained by the recognition and then the correction part 2 sends ''a'' as the 1st candidate to a display part 3, where it is displayed. An input operator once seeing the character that the operator does not intend to input has a brief flurry and then varies in skin resistance, and this variation is detected by a detection part 5 to send a correction signal through a decision part 6. Further, when ''wa'' as the 3rd candidate is displayed, it is the character that the operator intends to input, so the signal obtained by the detection part 5 has a normal value and no correction signal is outputted from the decision part 6.

Filed: 1987-04-20
Abstract: PURPOSE:To realize a solid-state image sensing device of high performance with a small number of manhours and high yield, by applying a two-layer wiring of the same metal, forming the lower metal electrode of a photoelectric conversion element with a first layer metal wiring, and forming the wiring of a drive circuit and a lead-out wiring from the upper transparent electrode of the photoelectric conversion element with a second layer metal wiring. CONSTITUTION:After the lower electrode of a photoelectric coversion element is formed with a first layer metal wiring 108, an amorphous silicon film 109 is deposited to form a transparent electrode 110. In the case where ITO is used for the transparent electrode 110, an occupied area by the first layer wiring region is small, because a wiring for a drive circuit is not finished. Further, there is no step-difference in a base substrate of the first layer wiring 108, so that the provability that cracks generate in the amorphous silicon layer is small. Therefor, the provability that an etching liquid reaches the first layer wiring 108 is also small. The resistivity of a second layer wiring 113-115 of Al is small, and its patterning properties is excellent. Thereby, a wiring 114 connecting the photoelectric conversion element and the drive circuit, and the lead-out wiring 115 from the transparent electrode 110 can be prevented from breaking.

CONSTITUTION:The light from a light emitting element 4 is conducted via a plane waveguide 2 to the optical fibers 1A, 1B. Photoelectric converters 7A, 7B are provided to an arm 11B so as to face the aperture ends of the fibers 1A and 1B. The light from the aperture end is equally projected to respectively four pieces of photodetectors while both fibers 1A and 1B do not oscillate. On the other hand, the fibers 1A, 1B are deformed vertically in parallel with each other and in the directions opposite from each other by Coriolis force Fc when the angular speed OMEGA is inputted thereto. The optical axes of the fibers 1A, 1B are displaced both in the same direction when the acceleration is exerted thereto. The displacement directions of the light spots from the fibers 1A, 1B formed on the quadrisected photodetectors vary with the angular speed input and acceleration input in the above-mentioned manner and therefore only the angular speed is detected by utilizing the same.
