Title: Defect detector
Inventor: MIYAZAWA SADAMU
IPC: G01N21/90
Filed: 1980-06-27
Abstract: PURPOSE:To enable the whole bottle-bottom to be inspected with a high accuracy, by a method wherein the light passing through the bottom of a bottle being inspected is received by means of an image pickup tube, the video signal is stored in a memory, and the stored data is read out through the address designation by means of a spiral scanning. CONSTITUTION:Through a diffusing plate 11, a lamp 12 irradiates a body 10 to be  inspected, which is carried thereto, from the direction of the bottle bottom. The optical image thereof is picked up by means of a TV camera 13, and the 1-frame picture thereof is converted into a video signal VS, which is then sent out. Said signal is converted into a digital signal DS in an A/D converter 20 and stored in a memory  30 according to the address designated by the write signal WR from a memory controlling curcuit 40. The stored data are read out in correspondence to the spiral  scanning position from the center of the body being inspected, according to the read- out signal from the memory controlling circuit 40 operated by a pulse generator  402. If the body 10 being inspected has any defect, there is a sudden change in the  data read out from the memory 30. Therefore, said change is discriminated by  means of a discriminating circuit 50, and said body 10 is discharged through a discharger 60.

Title: Rare gas discharge lamp lighting device
Inventor: SATO YOSHINORI
IPC: H05B41/392
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To attain modulated light lighting, suppress power loss of a switching transistor and an increase in heating value, and reduce an influence of high frequency noise and high frequency leakage current by controlling the input voltage of a high frequency generator which lights a rare gas discharge lamp. SOLUTION: This rare gas discharge lamp 15 is formed with a pair of main electrodes at the outer surface of a bulb which involves a phosphor layer at its inner surface, along the tube axial by being filled with xenon, and positive column forming range is large at the time of charging, therefore, light generation area is large. A high frequency generation device 20 is a chopper, and involves an insulating type output transformer, therefore, conduction of high frequency noise and leakage current by the main electrodes to input power source side is decreased. By a PWM control which controls the ON period of a switching device 30 which is formed at the front stage of the high frequency generation device 20, an on/off rate is changed, so that light intensity of the rare gas discharge lamp 15 is changed.  In this case, the base voltage and current of the switching transistor of the high frequency generation device 20 is not changed, thus it is possible to apply no burden.

Title: Time base correction circuit
Inventor: TANAKA SEIICHI
IPC: H04N5/956
Filed: 1994-03-31
Abstract: PURPOSE:To reduce the cost and the chip area by decreasing a circuit scale. CONSTITUTION:A TBC memory 7 uses a write clock WCK following to low frequency jitter of an input video signal to write the input video signal and uses a read clock RCK for a fixed frequency to read the video signal to eliminate the low frequency jitter. Furthermore, the TBC memory 7 is read after a 1H period from the write. A phase detector 21 uses a phase error between a WH signal for a horizontal period and a horizontal synchronizing signal HD and integrates a difference of a phase error before and after the 1H period with an LPF 14 to generate a 1st degree hold signal based on high frequency residual jitter. A phase shifter 9 shifts the phase of the video signal from the TBC memory 7 based on the 1st-degree hold signal. Since the time after the detection of the phase detector 21 till the 1st-degree hold signal is generated is coincident with a delay time by the TBC memory 7, an output of the TBC memory 7 is given as it is to the phase shifter 9.

IPC: H02M1/08
Filed: 1982-05-26
Abstract: PURPOSE:To perform an accurate phase control by a digital component by commonly using most of components for individual controllable electric valves which construct a polyphase power converter. CONSTITUTION:A zero detector 4 receives as a synchronous voltage a voltage between lines which is produced through a transformer from an AC side terminal, and generates a pulse whenever the voltages pass a zero point. A waveform shaper 5 synchronizes the output pulse of the detector 4 with clock pulse VCK of a microcomputer 11. Accordingly, a synchronizing pulse which provides a reference phase point for controlling the phases of individual thyristors is sequentially generated at the output terminal of the shaper 5. These pulses are, on one hand , to a counter 6, and, on the other hand, to a counter 8. The microcomputer 11, upon inputting of an interrupt signal  I tp, shifts to the execution of the prescribed interrupted program, discriminates a thyristor to be fired and generates a control pulse Vp for the thyristor to an output amplifier 12.
