Title: Reactor irradiation capsule and its temperature control method
Inventor: YASU TETSUNORI
IPC: G21C23/00
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To make the temperature of irradiated sample constant for improved data precision and reliability by incorporating a heater with winding pitch changed according to gamma exothermic distribution in each irradiation field into an irradiation capsule, adjusting heater output. SOLUTION: With the interval of double wall cylinder vessel of an inside cylinder tube 1 and an outside cylinder tube 2 as a gas gap layer 3, the heat which is gamma-heat-accumulated with argon gas, etc., sealed up is prevented from escaping in axis direction of an irradiation capsule. A heater attaching tube 7 is inserted into a core rod 8 integrated with the irradiation capsule, while a heater 13 is wound around a coil, and houses a thermocouple 10 inside of it. An electric heater 13 which controls a to-be-irradiated sample in the irradiation capsule to an arbitrary temperature is wound around the outside surface of the heater attaching tube 7 with the winding pitch changed according to gamma heat-accumulation distribution in each irradiation field.  By adjusting the heater output accordingly, irradiation can be performed with the entire irradiated sample at a constant temperature, without affected by the temperature change and gamma heat-accumulation distribution during reactor operation.

Title: Frequency measuring circuit
Inventor: NOSE TADASHI
IPC: H02H3/46
Filed: 1983-01-31
Abstract: PURPOSE:To enable a quicker response by a method wherein an input signal is shaped into a square wave to devide a clock signal by a measured value of the square wave during the period H and a value of counting division outputs for a fixed time is outputted as measured value of frequency. CONSTITUTION:An input signal fO is shaped in the waveform into f'O and a clock signal fC is turned to an fC/N signal via a division circuit 2. The signal is fed to a first counter 4 to be counted and fed to a rate multiplier 10. An FF9 produces an output signal of an inverter 6 as setting input and when counts of a second counter 7 reach the preset counts (n), an output is generated at an output port P1. While the setting output signal of the FF9 goes to H, an AND gate 11 is opened and an output signal of the multiplier 10 is fed to a third counter 12 to be counted sequentially. Counts M of the third counter 12 give a value proportional to the input signal fO. As the counts of the counter 7 reaches n+1, an output is produced so that the counts M are latched to be outputted as M'.

Abstract: PURPOSE: To produce the metal powder whose surfaces have been subjected to carburizing treatment and which is superior in abrasion resistance at high performance by providing a metal-powder-capturing ladle in which quenching oil is stored to the lower part of a plasma jet generator.  
     CONSTITUTION: Voltage is applied between the non-consumable electrode 6 and a water-cooled copper nozzle 7 of a plasma jet generator and inert gas such as Ar is flowed to let a plasma jet 8 of extra high temperature and high speed be generated. A metal wire material 9 of the same compositions as those of the intended powder is fed into this plasma jet 8. The metal wire material 9 is instantaneously melted by the plasma jet 8 and becomes fine molten metal powder 11 which then flies downward and jumps into the quenching oil 13 in the powder-capturing- ladle 12 connected to the lower pat of the device, where it freezes. At this time, the surfaces of the metal powder are carburized and harden to became the powder of superior abrasion resistance. The fine molten metal flown by this device is subjected to carburizing treatment without being contaminated by oxygen.
