Title: Control system
Inventor: TANAKA NAOKI
IPC: G09C1/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To reduce the complexity of control by relating plural partial systems by a common variable, synchronizing them through a chaos state and changing a parameter for one partial system so as to lead the other partial system to various uniform states. SOLUTION: For instance, the system is constituted of two partial systems (a driving system and a response system) and the driving system drives the response system by a common variable (v). When control parameters p, p' for the driving and response systems are set up p=p'=p0 under a condition that the Liapunov numbers of motional components in a direction crossing a synchronous hyperplane on which a variable (w) other than the common variable (v) of the driving system is equal to a variable w' other than the common variable (v) of the response system are negative, the response system is synchronized with the driving system and turned to a chaos state. At the time, only the driving system is controlled, the whole system is controlled so as to be turned to a uniform state and the control parameter (p) is slightly changed around the p0 to execute stabilized control.  Consequently various uniform state can be attained while suppressing the complexity of control to a low level.

Title: Pseudo-color reduction circuit for image pickup device
Inventor: TSUJI KIYOSHI
IPC: H04N9/68
Filed: 1988-02-25
Abstract: PURPOSE:To reduce the occurrence of a pseudo-color to a spike-shaped luminescent spot by providing a means to suppress a color signal in a video signal corresponding to an output signal from a high luminance extraction means. CONSTITUTION:A luminance signal is extracted from a video signal by a low- pass filter(LPF) 2. A video signal is inputted to a band-pass filter(BPF) or a high-pass filter(HPF) 3 to extract luminescent spot component, then inputted to a luminescent spot detection circuit 4 where low noise component is eliminated by clipping it or luminescent spot component higher than a limit level is extracted. Thus a gain of a gain controlled amplifier(GCA) 6 in which the color signal passed to a color signal processing circuit 5 is inputted, is controlled by said processed signal and a color signal in the part of the luminescent spot is spurred. As a result, the occurrence of a pseudo-color to a spike-shaped luminescent spot can be reduced.

Abstract: PURPOSE:To prevent the malfunction caused by an unstable clock for an integrated circuit which contains a phase control circuit where the oscillation of a master clock becomes unstable right after a power down state is canceled. CONSTITUTION:A counting operation is carried out by a master clock 250 in each cycle of a frame signal 120 of fixed frequency supplied from the outside of an integrated circuit 100. Then the oscillation frequency of the clock 250 is measured based on the count value, i.e., in a fixed time. If the measured oscillation frequency is normal, a stable clock 250 is judged. If not, an unstable clock 250 is judged respectively. When the stable clock 250 is judged, the clock 250 is used as a system clock 750 of the circuit 100. Thus it is possible to prevent the malfunction of the circuit 100 that is caused by an unstable clock right after a power control state is canceled.

Title: Water content measuring instrument for grain
Inventor: MORI TAIICHI
IPC: G01N27/04
Filed: 1986-02-28
Abstract: PURPOSE:To take a measurement with high accuracy by providing a detecting means which detects whether or not there is a grain to be tested at the entrance of a crushing part. CONSTITUTION:The tested grain presence/absence detecting means 11 is provided at the entrance of the crushing part and consists of a projecting element 11a and a photodetecting element 11b and each grain to be tested cuts off light, so it is confirmed whether or not the grain to be tested is supplied to an electrode roll part. A CPU 12 inputs a voltage-converted signal corresponding to the electric resistance characteristic to the crushed grain to be tested after A/D conversion 13 or a test-grain 'presence' signal obtained by the means 11. The converted voltage signal of the grain to be tested is converted into a water value, but only the voltage-converted signal which rises within a certain time after the detection signal is outputted is inputted as an effective grain voltage signal. Therefore, a voltage-converted signal which rises after the certain time and a converted voltage signal which rises again before a next tested grain detection signal is outputted are considered to be noise signals based upon circuit characteristic or remeasurement noise signals of a grain which stays sticking on an electrode roll. Those are made effective and the measuring operation is performed with high accuracy.
