Filed: 1991-11-21
Abstract: PURPOSE:To provide the wiring pattern detecting method and its device capable of inspecting a printed board with high reliability without overlooking a residual copper defect having a low reflection factor or a chip defect chipped with the surface only. CONSTITUTION:The excitation light containing no fluorescence is radiated to a printed board or a ceramic board 1 from a high-intensity light source 11, the light from the board 1 is split into two optical paths by a half-mirror 231, an image of fluorescence generated when the base material of the board 1 is excited by a filter 22 is formed on a detector 13 by an image forming lens 25, and a negative pattern of wiring is obtained from the detector 13. An image of the reflected light reflected from the surface of the wiring pattern of the board 1 by a filter 24 is formed on a detector 131 by an image forming lens 251, and a positive pattern of wiring is obtained from the detector 131. A defect such as the residual copper or a chip is correctly detected based on the negative pattern of wiring from the detector 13 and the positive pattern of wiring from the detector 131.

Title: Video signal processor
Inventor: FUJII TAKUYA
IPC: H04N5/783
Filed: 1999-10-27
Abstract: PROBLEM TO BE SOLVED: To display a picture in a desired position even in the case of special reproduction. SOLUTION: Plural kinds of video signals are inputted through a switch SW1 one by one, and ID data corresponding to input video signals are generated by a microcomputer 28. An ID data insertion circuit 36 inserts ID data generated by the microcomputer 28 to prescribed positions of effective horizontal lines. Video signals to which ID data are inserted are recorded on a magnetic tape by a VCR. When a video signal to which ID data has been inserted is reproduced from the magnetic tape, this reproduced video signal is inputted through the switch SW1 and is compressed (reduced) to 1/4 by compression circuits 14 and 16. A write controller 26 writes the reproduced video signal in a prescribed area on a memory 22 on the basis of ID data. Reproduced video signals written in individual areas are collectively read out by a read controller 32, as the result, plural kinds of pictures are divided and displayed on a monitor screen.

Title: Transmission circuit for video signal
Inventor: ISOGAWA TOSHIAKI
IPC: H04N5/18
Filed: 1986-12-23
Abstract: PURPOSE:To reduce irregularity in clamping levels and clamping noise by regulating the gains of an amplifier in a stage preceding a clamping circuit to be small during a clamping cycle. CONSTITUTION:During cycles other than clamping, an AGC voltage Va is taken out from a comparator circuit 23. At this time, a transistor Q1 is in off-state, and the voltage Va is supplied to the amplifier 21, and thus an AGC action is achieved for a signal S2 to be taken out. But in a clamping cycle, Q1 turns on, hence the voltage Va is not supplied to the amplifier 21, and its gain comes minimum, therefore, a noise Sn in a signal S2 also comes minimum. And in the clamping circuits 3, 5, 7 in the following stages, respective clampings are executed during a period when the noise Sn is minimum. As a result, the irregularity in the clamping levels and the clamping noise of signal S3, S5, S7 are remarkably decreased.

Title: Low noise light receiving device
Inventor: MIZUSHIMA YOSHIHIKO
IPC: H04B10/112
Filed: 1994-12-12
Abstract: PURPOSE:To transfer an optical signal in a low fluctuation state at low noise by adopting a contact capable of carrier injection for an electrode, connecting a light receiving element to a power supply via an external impedance whose impedance is higher than an internal differentiation resistance of a semiconductor substrate and providing an output of a signal when a signal light is applied to the semiconductor substrate. CONSTITUTION:A couple of electrodes are set to a semiconductor substrate indicating a photoconductive effect. A contact capable of carrier injection is adopted for the electrodes. A light receiving element 110 is connected to a power supply via an external impedance whose impedance is higher than an internal differentiation resistance of the semiconductor substrate. When a signal light P is applied to the semiconductor substrate, a low noise signal is outputted. The light receiving element 110 is provided with an optical input device superimposing a local light having a prescribed frequency difference with respect to a signal light onto a signal light to obtain an input light and an output device implementing optical heterodyne light reception. In this case, since a passing current of the light receiving element increases and an internal impedance decreases according to a local light intensity, a lower noise state is realized.

Title: Thermal transfer recorder
Inventor: IIDA AKIHIKO
IPC: B41J2/32
Filed: 1989-11-28
Abstract: PURPOSE:To prevent an image from being confused by making frictional force acting on an image receiving sheet always constant by a method wherein a common pressurizing mechanism between a thermal head and a platen is mutually established. CONSTITUTION:There thermal heads 1a, 1b, 1c are supported in a unitary manner with a head support component 6, and the support component 6 is pushed toward platen rollers 2a, 2b, 2c with a pressurizing spring 7. Further, the head support component 6 is so controlled with a pin 8 and a guide 9 sliding in contact with this pin 8 as to be movable only in a direction vertical to a carrying direction of a sheet. For instance, pressing force with the pressurizing spring 7 is taken as F, and a frictional coefficient to an image receiving sheet is taken as mu. When loads before and after the image receiving sheet 4 passes the thermal head 1a are compared, the load before passing is (F/3)mu X 3, and the load after passing is (F/2)mu X 2. Both becomes muF and no variation in loading occurs. Therefore, since the image receiving sheet 4 is always carried at a constant speed, confusion of the image at start of recording and at end of recording comes not to be generated.
