Inventor: TANIMOTO YOSHIO
IPC: H03D3/00
Filed: 1989-12-27
Abstract: PURPOSE:To realize phase synchronization detection without use of an external connector by generating a sweep signal of a voltage controlled oscillator based on the phase comparison between a carrier obtained in a PLL loop having the voltage controlled oscillator and an N-phase modulation signal and on the result of amplitude comparison between the comparison output and a reference voltage. CONSTITUTION:An N-phase modulation signal (a) is divided into two by a distributer 5, part of them is inputted to a 1st N multiplier 6, where the signal is subject to N multiple and a carrier signal (g) not subject to phase modulation is obtained. On the other hand, when a frequency of the N-phase modulation signal (a) exists in the lock range of a PLL loop comprising a phase detector 1, a phase error detector 2, a 1st low pass filter 3 and a voltage controlled oscillator 4, an output signal of the voltage controlled oscillator 4 starts locking of the frequency and phase rapidly. An output signal (h) of the phase comparator 8 passes through a low pass filter 9 and identified with a reference voltage signal (j) from a reference signal generator 10 at an amplitude processing 11. The reference voltage signal (j) is set properly to obtain a detection signal (k) discriminating the synchronizing state and the asynchronizing state is obtained.

Title: Device and method for encoding
Inventor: WATANABE KAZUO
IPC: H04N19/196
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To efficiently compress data while effectively avoiding the degradation of picture quality even concerning a high definition video signal by providing a coefficient correcting means for correcting a coefficient value for the unit of each fine block with an average value as a reference and a quantizing means, etc., for quantizing the coefficient data corrected by this means. SOLUTION: A coefficient processing circuit 23 calculates the average value of absolute values of coefficient values for the unit of a macro block concerning coefficient data D1 and outputs coefficient data D2. An inverse discrete cosine transformation(IDCT) circuit 24 performs IDCT processing to the coefficient data D2 outputted from the coefficient processing circuit 23 and outputs image data to a subtracter 3. Then, a discrete cosine transformation(DCT) circuit 5 performs DCT processing to the image data inputted to the subtracter 3, and these data are quantized by a quantizing circuit 6. Thus, since the average value is calculated and the coefficient data are corrected with the average value as the reference, even concerning the high definition video signal, the degradation of picture quality can be effectively avoided.

Title: Seat valve type three-way valve
Inventor: YONEZAWA KEITARO
IPC: F16K11/044
Filed: 1989-12-29
Abstract: PURPOSE:To reduce pressure excluding operating force so as to make a device compact by constituting it in such a way that the internal pressure of a valve chamber which acts, as valve closing force, on a valve on the outlet side, acts on a pressed area for closing valve which is obtained by subtracting a pressure excluding cross section from an unpressed cross section inside a valve face on the outlet side. CONSTITUTION:When a three-way valve 1 is changed to pressure hold condition Y from pressure supply condition X, a valve section 22 on the outlet side is closed and brought into contact with a valve seat 16 on the outlet side due to internal pressure of a valve chamber 4. At this time, a valve 23 on the inlet side is received by a valve stopper 33 on the inlet side, and clearance N is formed between both valves 22, 23. Internal pressure of a valve 4 on the outlet side acts only on a pressed area S3 for closing valve which is obtained by subtracting a pressure excluding area S2 of a pressure excluding chamber 27 from an un pressed cross section S1 inside a valve face 19 on the outlet side. As a result valve closing force which acts on the valve section 22 on the outlet side may be small. When the valve section 22 on the outlet side is opened by operating a pressure excluding operation means 37, its necessary force can do with the small force which opposes to the internal pressure which acts on the pressed area S3 for closing valve. For this reason, the operating force becomes light, and it is possible to manufacture a compact device.
