Title: Reactor core for nuclear reactor
Inventor: MASUDA HIROYUKI
IPC: G21C5/12
Filed: 1991-03-20
Abstract: PURPOSE:To enhance soundness of fuel by setting fuel inventory lower in the central region of reactor core than in the outer peripheral region thereby sustaining flatness of output distribution in the radial direction of reactor core through the entire combustion cycle. CONSTITUTION:A reactor core tank 1 is filled with moderator, i.e., heavy water 2, and a pressure pipe assembly 3 is loaded. Fuel rods having large diameter are arranged in the central region 3A of reactor core while fuel rods having small diameter are arranged in the outer peripheral region 3B thereof and thereby fuel inventory is low on the outer periphery. Fuel arranged in the outside region 3B has a high content of fissionable material and nuclear chain reaction is restrained in the initial stage of combustion cycle through the self- shielding effect. Since the effect for retarding combustion deteriorating rate at an infinite multiplication factor is offset by the low fuel inventory effect, i.e., the effect for accelerating the deterioration, for the fuel arranged in the region 3B, deterioration rate is substantially equalized for the central part and the outer peripheral part. Consequently, reaction rates of fuel in the regions 3A and 3B are sustained constant over the entire combustion cycle resulting in a uniform output distribution in the radial direction of reactor core 1.

Title: External synchronizer
Inventor: SATO YOSHIAKI
IPC: H04N5/04
Filed: 1993-03-17
Abstract: PURPOSE:To shorten the lock-in time beyond the variable range of a VCO oscillation frequency by performing the horizontal reset processing to combine the phases of external and internal horizontal synchronizing signals. CONSTITUTION:The phase locked loop consisting of a digital phase comparator 11 to a VCO 15 and a synchronizing signal generating circuit 5 is operated to delay the phase of the internal horizontal synchronizing signal behind the phase of the external horizontal synchronizing signal, thus leading in the phase, The phase of the internal horizontal synchronizing signal supplied to the digital phase comparator 11 is subjected to the horizontal reset processing by the synchronizing signal generating circuit 5 so that it slightly leads the phase of the external horizontal synchronizing signal. Consequently, the phase of the internal horizontal synchronizing signal which slightly leads the phase of the external horizontal synchronizing signal is immediately combined with the phase of the external horizontal synchronizing signal by the phase locked loop.

Title: Pop noise preventing circuit of audio equipment
Inventor: SHIYOUMURA ATARU
IPC: H04B1/10
Filed: 1983-03-31
Abstract: PURPOSE:To prevent pop noise by using a voltage dividing circuit connected between the positive and negative terminals of a power supply, a capacitor connected between the midpoint and ground, and a transistor(TR) whose base is connected to the midpoint and which discharges the negative power supply to ground through a resistor. CONSTITUTION:Since resistors R1 and R2 are selected so as to hold a base voltage of a TR4 zero while a main amplifier is actuated with a power supply turned on, the TR4 keeps inoperative. Although the operation of the main amplifier is stopped with a power switch turned off, since the voltage drop at positive side 101 of the power supply is faster than the negative side 102, a voltage is generated between the emitter and base of the TR4 thereby starting the operation of the TR4. The voltage at the negative side 102 is discharged through the resistor R3 and the TR4, the voltage rise is quickened by the share and the voltage curve is nearly coincident with the voltage drop curve of the positive side. As a result, since the final output stage of the amplifier is not held to the negative voltage, even if the power switch is turned on again, no pop noise is outputted from a speaker.
