Title: Optical head
Inventor: WATABE AKINORI
IPC: G11B7/135
Filed: 1983-08-19
Abstract: PURPOSE:To prevent the optical axis of a reflected light beam from shifting laterally and to control the positioning of a light beam in a focus and a track direction by moving an optical element which consists of an objective lens, quarter-wavelength plate, polarization prism beam splitter, etc., in one body to move in the focus or track direction. CONSTITUTION:The light beam when made incident along an optical axis 13 is deflected at right angles by an optical path conversion prism 21, made incident on and transmitted in a polarizing prism 17, and transmitted in the quarter- wavelength plate 16 to be focused on a discoid information carrier 12 through the objective. The reflected light beam from the discoid information carrier 12 passes through the convergent objective lens 11 and is transmitted through the quarter-wavelength plate 16 to perform conversion into a light beam which is polarized linearly at right angles to the polarization of the incident light beam, and the light beam is reflected by the polarization prism beam splitter 17, a reflecting prism 15, and the optical path conversion prism 22 and projected along an optical axis 14 of reflection. Therefore, the optical axis of reflected light never shifts even when optical elements 11, 15, 16, and 17 united in the track direction are moved.

Filed: 1983-08-17
Abstract: PURPOSE:To perform high-reliability continuity inspection by dividing the pattern of a printed wiring board corresponding to networks, and carrying out disconnection in a network and batch short-circuit inspection of all other pins, network by network. CONSTITUTION:Networks 1-2-5, 3-7, and 4-6 are formed in correspondence to the 1st, the 3rd, and the 4th reference pins 1, 3, and 4. Disconnection inspection is performed between pins 1 and 2, and 1 and 5 through a decoding circuit 4 with respect to the reference pin 1 to attain disconnection inspection in the 1st network. An all-active signal is outputted from a signal line D to perform batch short-circuit inspection of all pins except in the 1st network with respect to the reference pin 1. At this time, the latches C for the pins 2 and 5 are already set in the disconnection inspection, so the result of AND E is in failure and the pins in the 1st network are cut. The batch short-circuit inspection is completed momentarily, so network-by-network short-circuit inspection may spend a long time, eliminating the electricity accumulation of the wiring board.

Abstract: PURPOSE:To measure the shape and position of a body to be measured precisely in a short time by obtaining different signals between image signals of respective irradiation points obtained by a couple of image pickup means and image signals of last irradiation points respectively. CONSTITUTION:Plural places on the surface of the object body 1 in a specific direction within the overlap visual field of a couple of fixed image pickup means (image sensors 10a and 10b) which pick up an image of the object body 1 are irradiated successively with slit light from a light source and images of respective irradiation points formed with the slit light are picked up by the image pickup means. Then, an image processing means obtains and processes difference signals between image signals of the respective irradiation points and held image signals of last irradiation points. Consequently, noise components in the image signals are removed and only components of the irradiation points are exctracted, so the positions of the respective irradiation points are measured precisely. Every time the overlap visual field of both image pickup means is shifted by a specific quantity, said operation is performed repeatedly to measure the shape and position of the object body.

Title: Ttl logical circuit
Inventor: TANIZAWA SATORU
IPC: H03K19/088
Filed: 1981-09-28
Abstract: PURPOSE:To decrease a transient current flowing in the transient state of switching, by separately providing an off-buffer circuit drive transistor (TR) and an inverting TR, in place of an off-buffer circuit drive TR. CONSTITUTION:When a signal level at an input terminal A is smaller than a VBE, TRs2,3 of an off-buffer circuit are turned on and an inverting TR4 is turned off and an output terminal D goes to high level VOH. When the input signal level reaches VBE+Vf, an off-buffer circuit drive TR6 reaches the saturation state, and the potential of the collector C starts decreasing to the sum of a collector-to-emitter voltage VCE at the saturation of the TR6 and a cathode- to-anode voltage Vf of a diode D3 from the power supply voltage Vcc. Thus, when the potential difference between the collector C and the output terminal D of the TR6 becomes smaller than 2VBE, the TRs2,3 are turned off. The transient current of the TRs3,4 is reduced to zero at the transient state of switching.

Abstract: PROBLEM TO BE SOLVED: To prevent the production of interruption of automatic tracking by calculating a moving vector of a traced object based on a current coordinate of the traced object and a movement of the coordinate of the traced object in preceding several cycles so as to control interlockingly a plurality of video cameras. SOLUTION: A video signal output of one to N-sets of video cameras 1 is given to an input of a video signal changeover device 3, and a controller 2 calculates a coordinate of a traced object based on an installed location coordinate of the video camera 1 stored in a database, a distance between the video camera 1 and the traced object, a panning angle of the video camera 1 and the tilt angle of the video camera 1. Simultaneously a motion vector of the traced object is calculated based on a difference between a just preceding position of the traced object and a position of the video camera 1. When the traced object is at the outside of a tracing range of the video camera 1, the object position is estimated from the motion vector of the traced object and the video camera 1 having the coordinate in the traced range is selected.  Thus, automatic tracing is attained by interlocking of a plurality of the video cameras 1.
