Title: Method for loading nuclear reactor with fuel
Inventor: KUSUNO SADAO
IPC: G21C5/00
Filed: 1990-04-11
Abstract: PURPOSE:To reduce power generating cost without sacrifying the stop allowance of a reactor by specifying the sum total of the number of stay cycles of the fuel assembly belonging to a cell excepting the outer peripheral part of a core and a CC (control cell) within a reactor so as to equalize the same at every cell. CONSTITUTION:This nuclear reactor is constituted of cells wherein a crossed control rod is surrounded by fuel assemblies. The loading number of the fuel assemblies to all of cores is set to T, the loading number thereof to the core outer peripheral part is set to P, the loading number thereof to CC taking out or in the control rod during the usual operation of the nuclear reactor is set to C and the number of the fuel assemblies desired to be replaced in each cycle is set to N. At this time, the sum total of the stay cycles of the fuel assemblies belonging to the cells excepting the core outer peripheral part and the CC in the reactor is set to S and, as a rule, the sum total is made equal in all of the cells and set to the following quantity. That is, the value thereof is divided by the value of R=(T-C-P)/N and S is set to 10 when R is 3.4 - 4.5, to 12 when R is 4.5 - 5.5 and to 14 when R is 5.5 - 6.5. By this method, the stop allowance of the reactor can be sufficiently enhanced without damaging economical efficiency and motion capacity.

Title: Liquid crystal display device
Inventor: KURODA MITSUHIRO
IPC: G09G3/36
Filed: 1987-04-20
Abstract: PURPOSE:To uniformize the brightness on an image plane by changing the amplitudes of the voltages to be impressed to counter electrodes successively in a row direction. CONSTITUTION:The counter electrodes 4a, 4b...4n are divided to a plurality in each of respective lines and the respective counter electrodes are connected to a voltage setting circuit 8. The amplitudes of the voltages to be impressed to the counter electrodes 4a, 4b,...4n are successively changed in the row direction. The amplitudes of the counter electrodes are previously adjusted to the amplitudes increasing toward the lower lines and, therefore, the average of the effective values of the voltages to be impressed to liquid crystal cells 1 does not diminish and the brightness in the lower part of the image plane does not decrease even if the counter electrode potentials change during the time when the voltages to be impressed to the cells 1 are held. The brightness on the image plane is thereby uniformized.

Abstract: PURPOSE:To separate a stable and highly accurate composite synchronizing signal from a weak composite signal or a strong signal by using a comparator so as to allow its threshold voltage to be changed in response to the amplitude of an inputted video composite signal. CONSTITUTION:A means potential of a television composite signal is nearly at a common potential at a point A by selecting the time constant C1R1 larger the pulse width of a vertical synchronizing signal. A gate of an analog switch 2 is opened during the synchronizing signal period to charge a capacitor C2. A potential (point B) of the capacitor C2 keeps a negative peak voltage (synchronizing signal voltage), which is divided by a resistor through a voltage follower 3 to form a threshold voltage of a comparator 4. The threshold voltage (at point C) has a value between the potential of the synchronizing signal and a common potential, it is used as a reference voltage and the synchronizing signal is separated by the comparator 4. The analog switch 2 is switched again by using the separated synchronizing signal. The time constant C2R2 is set to a value far larger than the period of the horizontal synchronizing signal.
