Title: Chrominance component processing device
Inventor: OTSUKI TAKUYA
IPC: H04N9/45
Filed: 1987-03-20
Abstract: PURPOSE:To prevent disturbances of ACC and APC operations caused by noise just before a horizontal synchronizing signal, by deciding pulses as horizontal synchronizing signals only when widths of synchronizing separation output pulses are smaller than a prescribed width and turning on or off ACC and APC loop filters in accordance with the decision. CONSTITUTION:A synchronizing signal deciding circuit 32 decides that signals separated at a synchronizing signal separator circuit 31 are not noises, but horizontal synchronizing signals other than a vertical synchronizing period and controls the supply of clocks which actuate LPFs 20 and 21 in accordance with the discriminated results. Therefore, supply of an ACC or APC error voltage to an ACC or APC loop is prevented even if the output of the circuit 31 is disturbed by noises, etc., and chrominance components, variation of whose amplitude and phase is controlled, are always outputted to terminals 33 and 34. In this case, the circuit 32 decides the signals separated by the separator circuit 31 as horizontal synchronizing signals only when the pulse widths of the signals are higher than a 1st threshold and lower than a 2nd threshold.

Abstract: PURPOSE:To accurately measure the spectral ray width of a semiconductor laser without generating fluctuations in the spectral ray width by forming both ends of 1st, 2nd and 3rd optical fibers respectively diagonally with the side faces of the optical fibers. CONSTITUTION:Both end faces 21a, 21b to 23a, 23b of the 1st 2nd and 3rd optical fibers 21 to 23 are polished respectively diagonally to the side faces of the optical fibers. The reflected light rays from the diagonal end faces 21a, 21b to 23a, 23b of the optical fibers 21 to 23 are no longer passed in the same route as the route of the incident light and the return of the reflected light rays to a light source side is prevented. The diagonal angle theta is about 8 deg.+ or -1 deg. from the perpendicular direction. The optical coupling fails if this angle is larger. The reflected light rays return to the semiconductor laser to be measured if the angle is small. The spectral ray width is accurately measured in this way without generating the fluctuations in the spectral ray width.

Title: Dust conveyor of dust collector
Inventor: IIDA AKIO
IPC: E02B5/08
Filed: 1995-02-27
Abstract: PURPOSE: To enhance operability by immersing a perforated bucket in a sump whose maximum water level is not permitted to exceed the top end of the bucket, receiving all the water and dust that flow down within a chute, and then trapping and releasing the dust. CONSTITUTION: Dust trapped in water flowing through a water channel is raised by a dust collector, is thrown into a chute 8, conveyed by means of the water, and allowed to drop into a bucket 10 together with the water. Since the bucket 10 is immersed in a sump 17 held at an appropriate water level by an overflow weir 16, the dust is allowed to float in the bucket 10, is dispersed as it is stirred by the water flowing down, and can be received in large amounts. As the amount of dust in the bucket 10 increases, stirring and dispersing the dust smoothly becomes impossible and the dust is piled up to or above the level of water in the bucket 10. Then conveying of the dust is stopped by stopping of a pump 21, and the bucket 10 is lifted by means of an arm 15 and inverted to discharge the dust into a dumping site. Thus the dust can be trapped and conveyed efficiently.
