Title: Pll circuit
Inventor: KIYOFUJI TAKASHI
IPC: H03L7/091
Filed: 1990-01-31
Abstract: PURPOSE:To lock in a PLL quickly by setting a counter so that a trigger signal is sent from an n-ary counter to a pulse generator in a form of matching a timing of rising of a phase of a DFF signal in the initial state such as signal input start or drum rotation start at application of power. CONSTITUTION:An n-ary counter 6 counts an output of a voltage controlled oscillator (VCO) 5 repetitively up to 0-n and generates an output at two points of time when the count is 0 and 1/4.n. A 1st output generated when the count is 0 is fed to a 1st DRAM flip-flop (DFF) state detector 9 and a 2nd output generated when the count is 1/4.n is fed to a 2nd DRAM flip-flop (DFF) state detector 10. That is, the 1st and 2nd outputs with two different generating timings are generated from the n-adic counter 6 and the phase state of the input signal is detected in a different timing and a trigger signal is fed to a pulse generator 3 from the n-ary counter 6 in a form of matching the timing of leading of the phase of the input signal. Thus, the PLL circuit is locked in quickly.

Sewage overflowing from one end of a U-shaped trap flows into the main drainpipe channel through the weir to run against a side wall forming the main drainpipe channel. Sewage flowing toward the inlet side of the sewage running against the side wall is made to change the stream by the uneven step section and flows toward the outlet side. Accordingly, as the step of the uneven step section is made greater, the sewage flowing backward toward the inlet side is controlled more greatly to facilitate a quick drainage.
