    摘要: A time base correcting apparatus for reducing hindrance to a carrier chrominance signal due to clock jitter, when a sampling clock is generated by a digital circuit. In the time base correcting apparatus, a video signal is sampled with a clock synchronized with the video signal to be written to an FIFO memory. The video signal is then read out therefrom with a fixed clock to remove time base changes of the video signal. The fixed read clock is generated by multiplying two different frequency signals together, where one of the signals has a lower frequency approximately equal to (n+1/4) f (where n is an arbitrary integer, and f is a horizontal sync frequency) and using one of the resultant sidebands obtained through use of a bandpass filter. The read clock frequency is separated by 1/2 f from the other sideband frequency to reduce hindrance between the signals, and in turn to reduce viewable hindrances during the display of the video signal read out from the FIFO.

    摘要: In a system for eliminating time base fluctuation of a video signal having a synchronizing signal and a burst reproduced from a video disk, for example, the synchronism is first coarsely pulled in on the basis of the horizontal synchronizing signal and then precisely follows the time base fluctuation on the basis of the burst signal. A shift of the output synchronizing signal is corrected by using a phase detection of an input horizontal synchronizing signal when an output synchronizing signal is produced on the basis of the read address of a memory for eliminating time base fluctuation, thereby preventing, for example, a superimposed character using the output synchronizing signal from fluctuating on a picture.

    摘要: A time base correcting circuit is provided in which a time base error in a video signal is corrected by converting the video signal to a digital form which is then recorded into a memory with a write-in clock signal synchronized with a horizontal synchronizing signal or a color burst signal carried in the video signal, reading the digital signal with a read-out clock signal generated from a reference clock signal, and converting it into an analog form. In particular, a velocity error data is added to a corresponding horizontal blanking period of the video signal and after processing of the signals having time delays and continuation errors in the time base, the velocity error data is extracted from the horizontal blanking period of the video signal. Then, the read-out clock signal is phase modulated with the velocity error data extracted and used for correction of the velocity error in the video signal of analog form converted from its digital form.

    摘要: A microwave transmitting window for a plasma processing device. The window is a body of one or more pieces of the same or different dielectric materials. A surface of the window facing a microwave transmitting horn or waveguide is planar and extends perpendicularly to an axial direction. An opposite surface of the window is recessed such that the body has a non-uniform thickness between the two surfaces. The recessed surface can have various shapes and the overall size of the window can be equal to the size of a plasma formation chamber of the plasma processing device. The outlet of the plasma formation chamber can be formed in an end wall or the outlet can be formed by the inner periphery of the plasma formation chamber.

    摘要: A screw compressor includes a casing having low and high pressure spaces, a screw rotor inserted in a cylinder part of the casing, and a slide valve disclosed in the cylinder part. The screw rotor has a plurality of helical grooves forming a compression chamber. The slide valve is moveable along an axis of the screw rotor and faces an outer periphery of the screw rotor to form a discharge port to communicating the compression chamber with the high pressure space. Fluid in the low pressure space is sucked into the compression chamber, compressed, and then discharged to the high-pressure space when the screw rotor rotates. The slide valve includes a sealing projection located on a back surface of the slide valve opposite to the screw rotor, and separating the low and high pressure spaces from each other when the sealing projection is in slidable contact with the casing.
