Title: Reactor core and reactor operating method
Inventor: YAMAMOTO TORU
IPC: G21C3/328
Filed: 1995-04-27
Abstract: PURPOSE: To attain the same burnup as that of a reload fuel assembly by setting the combustion initial reactivity of the initial load core of a reactor specific times the combustion initial reactivity of the reload fuel assembly. CONSTITUTION: The conditions that the burnup of the initial load fuel becomes equal to that of the reload fuel are expressed as 1.05 <= initial load fuel reactivity/reload fuel reactivity (combustion initial stage) <=1.2 in consideration of the fact that an initial load core is constituted of one or several kinds of initial load fuels. The reactivity of the fuel in the core at the initial stage of combustion is nearly proportional to the enrichment of the fuel, and the conditions that the burnup of the initial load fuel becomes equal to the burnup of the reload fuel are expressed as 1.05 <= enrichment of initial load fuel/- enrichment of reload fuel <=1.2.  The reactivity of the initial load fuel evaluated on the assemption that it has no flammable poisonous substance at the initial stage of combustion is assumed to be equal to the reactivity of the reload fuel evaluated on the assemption that it has likewise no flammable poisonous substance.

Title: Torque detecting apparatus for rotary shaft
Inventor: GOTO YOSHIYUKI
IPC: G01L3/10
Filed: 1989-04-24
Abstract: PURPOSE:To improve detecting sensitivity and accuracy by constituting an oscillating circuit which is oscillated at the resonant frequency of an optical oscillating circuit with a resonant circuit and a detecting part, and detecting the difference in rotary angles corresponding to torque as the change in oscillating frequency. CONSTITUTION:A rotary shaft 1 is a driving shaft, and a rotary shaft 2 is a driven shaft. Then, the shaft 2 is rotated with the shaft 1. Torsion is generated in an elastic body which is provided between both shafts 1 and 2. Therefore, a rotary angle is generated. The gaps between detecting coils 31 and 33 and metal cores 32 and 34 changes. The inductances of the coils 31 and 33 changes. Namely, when a core part 21 of the core 32 is moved back and forth in the cavity part of the coil 31, the eddy current generated in the core 32 changes, and the inductance of the coil 31 changes. With this change, the resonant frequency of an LC series circuit Kx which is coupled with a sensor part Jx changes. The oscillating frequency in a detecting part Lx changes based on said change. Thus an output fx is obtained.

Title: Power-on resetting circuit
Inventor: UEDA CHIHARU
IPC: H03K17/22
Filed: 1981-07-02
Abstract: PURPOSE:To prevent malfunction due to variation in power voltage, etc., even if the values of a capacitor and a resistance are increased so as to reduce the influence of the rising time of the power voltage, by connecting an MOS transistor (TR) in parallel to the resistance. CONSTITUTION:When a power voltage is applied between power terminals 10 (VDD) and 11 (VSS), the voltage at the connection point 14 of a capacitor 12 and a resistance 13 approaches from VSS to VDD as the power voltage rises and then falls gradually down to VSS, but when it reaches the inversion level VT of an inverter 15, the voltage at its output terminal is inverted from VSS to VDD to turn on an MOSTR16 with relatively low in resistance, and thus the value of the resistance between the connection point 14 and power terminal 11 is decreased to lower the level at the connection point 14 to VSS rapidly. The time up to the inversion of the inverter 15 depends upon the capacitor 12 and resistance 13 and after a setting pulse is outputted temporarily to invert the inverter 15, the MOSTR16 held in the on state holds the connection point 14 at VSS.
