Title: Method of charging spent fuel body
Inventor: UEDA KIYOSHI
IPC: G21C19/40
Filed: 1988-11-08
Abstract: PURPOSE:To ensure subcriticalness of a spent fuel body by continuously monitoring the effective multiplication constant accompanying the charge of spent fuel bodies. CONSTITUTION:When spent fuel bodies are charged in a housing vessel such as a spent fuel transport vessel or a spent fuel rack having many housing holes for charging the spent fuel bodies, a neutron level with which the spent fuels spontaneously releases is successively monitored to precisely evaluate a neutron multiplication characteristic on the basis of the detected level. At the time of the charge or taking-out of the spent fuel bodies, critical safety can sufficiently be ensured in a condition in which the multiplication characteristic heightens extremely. In other words, in the case where a neutron flux level is being monitored, the spent fuel bodies are charged and a fear in which the neutron flux level exceeds the allowable limit occurs, the housed spent fuel body of the largest neutron multiplication characteristic is pulled out from at least one housed hole in the housing vessel can be subcriticalness of the spent fuel bodies can be ensured by charging non-fuel bodies which make it impossible to charge the spent fuel bodies in their housed holes.

Title: Impact print head
Inventor: MIYAZONO YUTAKA
IPC: B41J2/28
Filed: 1989-10-26
Abstract: PURPOSE:To improve the driving efficiency by a method wherein a contact part at which an armature and a core are constantly in contact with each other is formed on an end face of a printing wire-side pillar projection part of a core. CONSTITUTION:A U-shaped core 1 is provided with an outer pillar projection part 1d and an inner pillar projection part 1e. An armature 3 is made rotatable while constantly coming into contact with an edge 1a of an end face 1c of the inner pillar projection part 1e. A sub-core 4 disposed on an end face 1b of the outer pillar projection part 1d functions to improve a magnetic efficiency of a magnetic circuit consisting of the armature 3 and the U-shaped core 1. An electric conduction to a coil 2 results in the armature 3 being attracted to the end face 1c of the inner pillar projection part 1e of the U-shaped core 1. With this attraction, a printing wire 4 moves in a direction of an arrow A to apply an impact force to an ink ribbon 8. As a result, an ink of the ink ribbon 8 adheres to paper 9, and a dot is formed thereon. Since a distance from a contact part 1a to the printing wire 4 can be decreased in this manner, a smaller inertia moment and a smaller gap (g) can be realized to improve a drive efficiency.
