  • Patent number: 8699652
    Abstract: A control rod for nuclear reactors includes four wings including neutron absorbers containing hafnium, a front end structural member which has a cross shape in cross section and includes brackets bonded to the leading ends of the wings, and a terminal end structural member which has a cross shape in cross section and includes brackets bonded to the tailing ends of the wings. The four wings are bonded to a wing-bonding member including a cross-shaped center shaft so as to form a cross shape. The front end structural member and the wing-bonding member are made of a zirconium alloy. The wings include neutron-absorbing plates having neutron-absorbing portions and each have an outer surface which is opposed to a fuel assembly and at which a hafnium-zircaloy composite member covered with zircaloy is disposed. The neutron-absorbing plates are opposed to each other with trap spaces disposed therebetween.

  • Patent number: 6752659
    Abstract: A waterproof connector is provided with a connector housing having a mating hollow to which an opposing connector is fitted, a seal fitted to an opposite side to the mating hollow of the connector housing, and a rear holder inserted and fitted to the connector housing. The seal is further provided with a plurality of through holes to which cables provided with terminals at front ends are respectively inserted, and the rear holder is provided with insertion holes communicating with the through holes respectively. The rear holder allows the cable to pass through at a time of being inserted to a temporary engaging position, and presses the seal so as to fix at a time of being inserted to a regular engaging position. The insertion holes are extended so as to have a length at a degree at which a front end thereof is not brought into contact with lips of the through holes even when the inserted terminals are inclined.

  • Patent number: 6558179
    Abstract: A waterproof connector is constituted by a connector housing provided with a mating hollow to which an opposing connector is fitted and a terminal housing protruded within the mating hollow, a first packing pressure contacted with the opposing connector within the mating hollow so as to be closely attached to a periphery of the terminal housing, and a slide arranged between the terminal housing and the first packing. The connector housing receives a plurality of cables provided with terminals at front ends so as to hold a second packing therebetween. The slide is provided with a plurality of slits being parallel to a sliding direction and respectively inserting the terminals, and a retaining portion extending toward the first packing in one end portion. The slits prevent the terminals from falling off in a side of the retaining portion, and allow the terminals to pass through in an opposite side.

  • Patent number: 6428332
    Abstract: A connector for-use-on-board includes a bar-like terminal protruding from a connector housing. A forward end of the terminal is soldered to a printed circuit conductor of a board. A position-regulating hole is formed in such a way as to pass through a position in the vicinity of the forward end of the terminal in a direction perpendicular to an axial line of the terminal. A position-regulating protrusion protrudes from the connector housing and is loosely fitted into the position-regulating hole with a prescribed clearance.
