Title: Chroma noise reduction circuit of pal system
Inventor: KIMURA ICHIRO
IPC: H04N9/84
Filed: 1995-12-14
Abstract: PROBLEM TO BE SOLVED: To obtain the chroma noise reduction circuit of the PAL system equivalent to that of the NTSC system in terms of the cost as well as the characteristic by providing an R-Y axis inversion circuit and a 1H delay line. SOLUTION: An R-Y axis inversion circuit 10 and a 1H delay line 11 are provided in place of a 2H delay line having been provided for a conventional circuit. A signal inverted by the R-Y axis inversion circuit 10 is equivalent to the original signal delayed by 1H substantial. Thus, the signal delayed further by 1H in the 1H delay line after that is in matching with an output of the 2H delay line having been provided for a conventional circuit in terms of the phase. The R-Y axis inversion circuit 10 is realized with a comparatively simpler configuration than that of the 1H delay line 11 and other circuits except the 1H delay line 11 are easily integrated in a 1-chip IC.  Thus, a comparatively inexpensive 1H delay line is adopted for a component internally mounted with respect to the integrated circuit similar to the case with the NTSC system and the cost of this system is equal to that of the NTSC system.

Filed: 1992-12-07
Abstract: PURPOSE:To allow a broadcast station desired to be received to be easily preset optimizingly by storing selected frequency data with a highest reception intensity signal to a storage means when plural selection frequency data having a same network code are in existence. CONSTITUTION:A control means 28 changes sequentially frequency data given to a selection reception circuit 20 to allow the circuit 20 to scan reception frequencies.

Furthermore, when plural selection frequency data having a same network code are in existence, the control means 28 stores the selected frequency data having a highest level of the reception intensity signal among plural selected frequency data to the storage means 30. Thus, the broadcast station desired for reception is easily preset optionally.

Title: Recirculation flow controller
Inventor: NISHIYAMA HIROYUKI
IPC: G21D3/00
Filed: 1990-11-28
Abstract: PURPOSE:To prevent unnecessary low reactor water level/emergency plant stop and operation in the over limit region by running back the recirculation pump to an optimum runback speed according to the operational state in the case of lack of supply pump capacity. CONSTITUTION:An arithmetic circuit 41 calculates an optimum runback reaching speed signal 41c as a function of core flowrate signal 41a and flow force signal 41b and inputs 42c to a memory circuit 42. The output 42a of the circuit 42 varies in accordance with the input 42c when a switch 42b is closed, and maintains the value of the immediate previous input 42c when the switch 42b is opened. That means, a recirculation pump speed demand signal 45 and an output 42a are switched at switches 43a and 43b to be a recirculation pump speed command 44. If the water supply pump stops during operation by some reason and the startup of a backup pump also fails, a water supply pump capacity lacking signal 46a turns on and the switch 43a and 42b close and the switch 43b opens due to the recirculation runback signal 46. Then the signal 46a decreases to the speed of signal 41c calculated for the operation condition immediately before the signal 46a turns on. Therefore, in the case of a single pump trip, the region of emergency plant stop is minimized.

Filed: 1989-12-20
Abstract: PURPOSE:To avoid the bypass of a transmission signal due to the dispersion in a characteristic of a connected line by revising a line termination characteristic of a 2/4-wire conversion means so that a generated tone signal is not bypassed to the receiver side. CONSTITUTION:While a transmission signal TS is fed to an inverting input terminal of an inverting amplifier 20b via an input resistor R1 and a variable resistor 20c, the signal is inverted by an inverting amplifier 20a and fed to an inverting input terminal of the inverting amplifier 206 via an output resistor R2 and an input resistor R3. Thus, the signal components of the transmission signals TS whose phases are inverted to each other and whose signal levels are identical are fed to the inverting input terminal of the inverting amplifier 20b, resulting that the signal components of the transmission signals TS included in a signal RS are cancelled together. Thus, the dispersion in the characteristic of the line is automatically absorbed.
