Title: Method and device for processing video signal
Inventor: FURUHATA TAKASHI
IPC: H04N19/00
Filed: 1985-01-25
Abstract: PURPOSE:To stabilize a sampling clock and to make it secure by using an oscillation output having a constant frequency instantaneously locked in phase with synchronization information included in the input video signal as the sam pling clock of an input video signal. CONSTITUTION:A horizontal synchronizing signal (b) is separated from the input video signal from a terminal 10 to be outputted, and the pulse (c) of the prescribed time width is outputted at a monostable multivibrator circuit 12. The video signal is separated from a burst signal, and supplied to an NAND gate 13. Therefore, only a burst pulse (d) based on the burst signal is outputted from the NAND gate 13 and supplied as a command signal for starting the oscillation of an oscillating circuit 50 to a terminal S. Since a control voltage VC is supplied to other terminal V, a control voltage VC controls variably the oscillation frequency of the oscillating circuit 50, and an oscillation start phase is instantaneously decided and multiplied and outputted as the sampling clock.

In terms of the configuration, since a conventional feed pipe is separated into an upper and a lower parts and a lower part reinforcing material 6 is attached to the peripheral part of a rotor supplying inlet 23 in the way it can be detached freely, no gap is needed between the rotor supplying inlet 23 and a feed pipe and the diameter of the supply routes of raw materials to be crushed can be extended by the degree of the gap. The supply amount of the raw materials to be crushed to the inside of a rotor 2 is increased. Also, the raw materials to be crushed which are thrown to the inside of the rotor 2 are usually rebounded but, since the peripheral part of the supplying inlet 23 is completely protected by the lower part reinforcing material 6, the part is prevented from wearing.
