IPC: H04N5/21
Filed: 1986-03-10
Abstract: PURPOSE:To reduce the noise without the deterioration of picture quality by controlling the characteristic of generation of a correction signal at low and high frequencies of picture. CONSTITUTION:A present input television signal x inputted from a terminal 1 is subtracted from a forecast signal x' from a forecast circuit 41 by a subtractor 11 to obtain a forecast error signal epsilon, which is led to a low pass filter 51 and its low frequency component epsilonL is converted into a control signal controlling the characteristic of a correction signal generating circuit 31 by a control circuit 61. A two-dimension spatial low pass filter is adopted as the low pass filter 51. Thus, the edge component and noise are separated and each horizontal/vertical edge is outputted as a low pass filter output and the low frequency component epsilonL is increased. Thus, the correction signal epsilon' is decreased at each horizontal and vertical edge and timewise fog is hardly caused.

Title: Clock abnormality detection method
Inventor: AKEIE MIKIJI
IPC: H04L7/00
Filed: 1989-03-02
Abstract: PURPOSE:To detect an abnormality of a clock for subsidiary synchronization in which the frequency is largely deviated and an adverse effect is imposed onto the system by monitoring an input voltage to a voltage controlled oscillator. CONSTITUTION:A phase comparator 1 and a loop filter 2 in a subsidiary synchronization clock generating circuit 5 convert a phase difference between subsidiary synchronization clocks C1 and C2 into a voltage and give the converted voltage to a voltage controlled oscillator 3 as an input voltage. The voltage controlled oscillator 3 generates a clock having the frequency in response to the input voltage as the subsidiary synchronization clock C1. Then the input voltage to the voltage controlled oscillator 3 is monitored by a voltage monitor 4 and an alarm is raised when the monitored input voltage exceeds a specified voltage range. Thus, a large deviation in the frequency of the subsidiary synchronization clock giving an adverse effect onto the system is quickly detected.

Title: Gain control amplifier
Inventor: SASE MASATOSHI
IPC: H03G3/10
Filed: 1985-03-14
Abstract: PURPOSE:To have a correct control characteristic in the gain control amplifier to give to a pair of inputs of the succeeding differential amplifier after a pair of output electric currents of the preceding differential amplifier is received by a PN junction by having a constant electric current load at the output part in the preceding differential amplifier. CONSTITUTION:After a pair of output electric currents of a preceding differential amplifier 1 are received by the PN junction (diodes D1 and d2), the current is given to a pair of inputs of a succeeding differential amplifier 2. A direct current electric current I0 overlapped to the PN junctions D1 and D2 is made variable and the gain is controlled. The preceding differential amplifier 1 is provided with a constant electric current load (I0+I1) at the output part. In an output point A(A') of the amplifier 1, the signal electric current, which flows at the amplifier side, is +x, and then the electric current, which flows at the A point, is constant (I0+I1), Therefore, the signal electric current, which flows from an A point to the outside, goes to be -x. The corresponding relation is never changed even when the direct current electric current I0 to control the gain for overlapping to the PN junction (D1 and D2) is made variable. Consequently, when I0 is made variable, the proportional relation of the resistance of the PN junction and the amplifier gain goes to be completely of a straight line system.

Abstract: PURPOSE:To make the length of optical path shorter, to make the size smaller and to realize lower loss, by disposing spherical lenses and a thin optical sheet relatively. CONSTITUTION:When light (solid line arrow) is inputted from a terminal A, the light is made into parallel rays with a spherical lens 4A. Part thereof is reflected by a thin optical sheet 5 for branching to a terminal B side, and the remaining part transmits through a terminal C and is thus branched. The respective rays are outputted from an optical fiber 1 through spherical lenses 4B, 4C. Conversely, when the light is inputted from terminals B and C, the rays are coupled to the terminal A in the route opposite to the above-mentioned route. The input light (dotted line arrow) from the terminal C is branched to the terminals A, D by the effect similar to the above-mentioned effect, and conversely, the input light from the terminals A and D is coupled to the terminal C, thus the device is a bidirectional optical branching and coupling filter in terms of function. The optical branching and coupling filter of variaous branching ratios is realized by changing the branching ratio of the sheet 5.
