Title: Semiconductor laser
Inventor: WATANABE NOZOMI
IPC: H01S5/026
Filed: 1986-03-10
Abstract: PURPOSE:To eliminate a light reflecting surface for forming an optical resonator by providing first and second optical guides connected with a light emitting unit, and a feedback guide having first and second optical transfer units. CONSTITUTION:An optical looplike feedback guide 23 connected with first and second photodetecting diodes 4, 4a has first and second optical transfer units 23a, 23b which approach to first and second guides 21, 22 of lengths L1 and L2 in parallel with the guides 21, 22 for communicating lights to be propagated. The propagating length of the light propagated between first and second optical transfer units 23a and 23b to be fed back to a light emitting unit 3 is integer times as large as the wavelength of a laser light to generate an optical resonance in an active layer. Since a quantum amplification is performed due to inductive emission in the unit 3 by such guides 23, the light reflecting surface for forming an optical resonator can be eliminated.

IPC: G03D13/00
Filed: 1988-03-03
Abstract: PURPOSE:To expand the range of a sheet which can copy a color image by transcribing the color image on the photosensitive pressure sensitive sheet which has an adhered adhesive layer to other sheets such as a post card, film, etc. CONSTITUTION:The adhesive strength of the adhesive layer 7 is specified so as to permit the adhesive strength between the adhesive layer 7 and the photosensitive pressure sensitive sheet 11S becomes stronger than the adhesive strength between the adhesive layer 7 and a base sheet 8. Therefore, the adhesive layer 7 is removed from the sheet 8, and the adhesive layer 7 adheres to the sheet 11S. Then the sheet 11S passes through a heat roller 18 under the condition that the sheet 11S is put on a manually inserted sheet 19 such as the post card. At this operation, the adhesive strength is specified so as to permit the adhesive strength between the sheet 19, the adhesive layer 7 and a developer layer 2 becomes stronger than the adhesive strength between the sheet type supporting body 1 and the developer layer 2. Thus, the developer layer 2 is removed from the supporting body 1, and the developer 2 adheres to the sheet 19, and the color image on the sheet 11S surface is transcribed to the sheet 19.

Title: Ophthalmologic apparatus
Inventor: UCHIDA KOJI
IPC: A61B3/14
Filed: 1996-02-15
Abstract: PROBLEM TO BE SOLVED: To accomplish continuous measurement smoothly at a proper timing by avoiding inadvertent measurement and photographing. SOLUTION: When a signal of an alignment light receiving element 15 exceeds a reference value showing an allowable range of measurement, a CPU 25 sends a solenoid drive signal to a solenoid drive circuit 31 and a forbidding circuit 30 is operated based on a timing of a solenoid drive signal to forbid further reception of a solenoid signal. At the same time, a hold signal is sent to a sample holding circuit 28 to hold a signal level of an alignment light receiving element 15 immediately. When any signal is lower than the signal level, a unforbidding signal is sent to the forbidding circuit 30 from a comparator circuit 29. When the solenoid drive signal is stopped while the unforbidding signal is already sent to the forbidding circuit 30, the forbidding circuit 30 stops its operation to allow the reception of the solenoid signal.

Title: Method and equipment for recording video information on tape recording medium
Inventor: GERUTO RAIME
IPC: H04N9/80
Filed: 1990-03-01
Abstract: PURPOSE: To substantially increase tape speed by recording frequency bands of contents successively transmitted to tilt tracks of a tape recording medium and shifting the recording frequency bands of the contents by a specific frequency quantity successively and relatively to each other according to a repetitive program processing. CONSTITUTION: A recording frequency band 11 of video information of the contents of tilt tracks to be recorded by frequency modulation is shifted to the back of respective 2nd tilt tracks according to a specific contact repetitive shift sequence, e.g. by a specific frequency shift of 100kHz. A luminance frequency band 25 includes frequencies assigned to separated luminance values which adjoin to frequency limit side bands 26 and 27 of combination frequencies of those luminance frequencies. During the frequency shift period, since a color frequency band 9 which is not detected is very small in level, it is not detected within a level range that the recording frequency band is dominant.

Title: Positioning unit of electron-beam exposure unit
Inventor: SHIMAZU NOBUO
IPC: H01L21/027
Filed: 1978-04-28
Abstract: PURPOSE: To shorten the positioning time for electron-beam exposure by making use of a vibrating method as it is called and a direct feedback loop to a deflection part.  
     CONSTITUTION: Analog switches 12 to 14 all turn ON by a start command so as to generate 15 a sine wave, and a beam vibrates at mark 18 on a sample surface. A shift between the center of the mark and the vibration center is detected 21 and a voltage value equivalent to the shift is outputted from lockin amplifier 23. Output information is negatively fed back to the deflecting plate by way of feedback-amount setter 24 and driving amplifier 16 to correct the shift and when the shift is zero, the output of amplifier 23 is zero, so that automatic positioning will be realized via the direct feedback loop. When the voltage of output information 23 reaches a fixed value, comparison information 24X is generated and the feedback-amount setting output voltage is stored 24 via control part 11. Memory information 25 is sent to integration control part 10, where center information of mark 18 before the positioning is given, and switches 12 to 13 turn OFF as soon as storing 25 ends. At this time, the beam vibration stops in the center coincidence stage by memory 25. Exposure-position information is inputted to amplifier 16, where the exposure position is fixed on the basis of the mark center.

Title: Handwriting recognition device
Inventor: ISHIZUKA YASUSHI
IPC: G06F3/0488
Filed: 1995-03-10
Abstract: PURPOSE: To recognize a handwritten character including a (running hand character) and a (simplified form character) stably at a high recognition rate. CONSTITUTION: A dictionary storage part 10 stores a reference pattern in unit of sub-pattern easy to write with one stroke. A stroke processing part 5 extracts a feature point representing the feature of a curvature part in advance before normalization. A feature resampling part 8 performs the normalization, interpolation and noise elimination at every chain of stroke, and interpolates an off- stroke section with the feature point. A character recognition part 9 performs DP matching using the reference pattern in unit of sub-pattern. In such a way, the feature of the curvature part is prevented from being lost due to the normalization by sampling the feature point of the curvature part before the normalization.  Also, the accuracy of the DP matching is improved and a time is reduced by the feature point extracted by using both an equal division method and an angle method and a standard pattern for every sub-pattern. Also, it is possible to deal with the (running hand character) and the (simplified form character) by performing write with one stroke by interpolating the off-stroke section.

Abstract: PURPOSE:To enable precise determination for the condition of suck-up of an electronic part vacuum-absorbed by a suck-up nozzle, by identifying data of vacuum upon suck-up of the part which are transmitted from an analog output type vacuum sensor with a reference vacuum determining range. CONSTITUTION:An analog output type vacuum sensor 17 which is disposed in an air circuit 8 for a suck-up nozzle 4a between the latter and a vacuum producing device 9 disposed in the air circuit 8, detects a degree of vacuum before suck-up of a part, and transmits detected data to a CPU 11 which compares the degree of vacuum with a reference degree of vacuum so as to compensate an OK determining area coping with the difference between the detected degree of vacuum and the reference degree of vacuum. This compensating value is empirically obtained, and is previously stored in memory in the CPU 11. The CPU controls an XY robot 5 so as to actuate the suck-up nozzle 4a which accordingly sucks up a part 2a.
