Title: Scanning type optical microscope
Inventor: HORIKAWA YOSHIAKI
IPC: G02B21/00
Filed: 1985-05-28
Abstract: PURPOSE:To obtain a confocal type image for detecting transmission by arranging a peak value detection type photodetector array on an object image surface or near the image surface so that a peak value can be detected only when dot-like light reaches just above each photodetector element of the photodetector array. CONSTITUTION:An optical beam 10 from a laser is made incident upon the 1st light deflector 14 and the deflected optical beam 15 is made incident upon the 2nd light deflector 18 through pupil transmission lenses 16, 17. These light deflectors 14, 18 are used for horizontal and vertical scanning and a fine spot scans the surface of a sample 21 two-dimensionally as rasters. The optical beam transmitted through the sample 21 forms fine spots 28, 29 on an image surface 27 through a condenser lens 25 and an image forming lens 26. If the peak value detection type photodetector array 30 is arranged on the image surface 27, each photodetector element 32 detects only the quantity of light obtained when the fine spot 31 is located just above the element 32. Thus, the confocal type image can be obtained.

Filed: 1985-05-27
Abstract: PURPOSE:To enable the dertermination of the phase of a repeating stress at which an AE (acoustic emission) wave is generated, by performing and resetting the measurement of phase information of the repeating stress at each cycle thereof to output phase information when the AE wave is generated. CONSTITUTION:When a stress signal is inputted into a comparator 1, a high level signal is outputted to a one-shot multivibrator 3 only while it is larger than threshold TH and the multivibrator 3 is triggered with the rising of the high level signal to obtain a one-shot pulse. A counter 5 is reset by the pulse to turn the contents to zero and advances by '+1' in response to a pulse from an oscillator 7. As an AE signal is outputted from a sensor 11, the contents of the counter 5 is latched with a latch 9 at the start of the rising thereof and thus, phase information of a repeated stress at the time point when the AE wave is generated is given.

Title: Video camera and contour emphasis device
Inventor: ASAIDA TAKASHI
IPC: H04N5/208
Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To obtain a stable video output with reduced noise by extracting a minimum signal among signals corresponding to a plurality of pixels before and after a video signal and providing an output of the extracted signal to a compression means so as to avoid a level of a contour emphasis signal from being largely changed between pixels even when a level of the video signal is varied between the picture elements. SOLUTION: A low frequency component Si from a low pass filter 171 is given to a minimum value extract circuit 173, which selects a minimum signal among three signals, that is, a signal before being latched by a D flip-flop and signals latched by D flip-flop circuits 174, 175. Thus, a signal with a higher level is not in existence in an output signal Sm of the minimum value extract circuit 173. The output signal Sm of the minimum value extract circuit 173 is compressed for a level by a level depend circuit 178, resulting that a detail signal is not deflected large when the output signal is multiplied with the detail signal and no large noise is produced in a camera output.

Title: Ecl logic circuit
Inventor: SAITO TAICHI
IPC: H03K19/086
Filed: 1990-05-02
Abstract: PURPOSE:To allow even an active pull-down ECL circuit to form an E-dot by providing a circuit controlling a bias voltage of an active pull-down circuit according to an emitter follower current to the ECL circuit provided with the active pull-down circuit. CONSTITUTION:A current of an emitter follower Q4 is detected to adjust a base bias of a transistor(TR) Q5. A current of the Q4 depends on a current at an output OUT, and when a wired-OR is employed for the output OUT, the output current depends on number of ECL circuits at an H level. Number of wired-OR circuits is 2, and the level of the one circuit changes from H to L and the other circuit remains at an H level, then the current of the Q4 is halved, and the base bias of the TR Q5 is decreased more than that when the said current is equivalent to 1. Then even when the drive by active pull-down is applied, the base bias of the TR Q5 and, accordingly, the current of the TR Q5 does not increase so much. Thus, spike noise caused at an H level is not too high.
