Abstract: A waterproof connector (10) includes a female housing (30) formed with cavities (31), and female terminals (20) connected to ends of wires (W) are inserted into the cavities (31) from behind. Shorting terminals (50) are accommodated in terminal accommodating portions (40) in a front part of the housing (30) to short adjacent female terminals (20). A one-piece rubber plug (60) is fit into a rear part of the housing (30) and includes through holes (62) through which the wires (W) are to be inserted. A rear holder (70) is mounted into the housing (30) to retain the one-piece rubber plug (60). Recesses (65) are provided on the one-piece rubber plug (60) in areas behind the terminal accommodating portions (40). Compressing protrusions (75) project from the rear holder (70) and are press-fit into the recesses (65) from behind.

Abstract: Cavities (13A) in which first terminal fittings (30A) are accommodated are at one side of shorting terminal accommodating chambers (17) arranged between cavities (13) in a height direction. Second cavities (13B) in which second terminal fittings (30B) are at the other side in the height direction. An escaping portion (23) is formed on a partition wall (22) between the shorting terminal accommodating chamber (17) and the second cavities (13B) in which the second terminal fittings (30B) are accommodated and allows resilient contact pieces (41) deformed by a short releasing portion (84) to escape. A front holder (70) is mounted on the front surface of a housing (10) and includes insulating portions (75) for insulating between the resilient contact pieces (41) and the second terminal fittings (30B) by being located at the side of the second cavities (13B) at the other side of the escaping portions (23) in the height direction.

Abstract: A connector (10) has terminal fittings (11) extending from a housing (12) and connected to a board (50). A casing (51) is mounted on the side of an upper surface (12U) of the housing (12) and covering the board (50). Liquid retaining portions (28) are formed on the upper surface (12U) of the housing (12) by connecting longitudinal grooves (29) extending in a front-back direction and horizontal grooves (31) extending in a lateral direction. Thus, the connector (10) prevents the intrusion of liquid to the board (50) along an upper surface of the housing (12).

Abstract: A connector is configured such that a casing for covering a board is to be mounted on an upper surface of a housing. Connector fitting receptacles are provided side by side in the housing while being spaced apart in a horizontal direction and mating connectors can fit therein. A lever accommodating receptacle is arranged above the connector fitting receptacles and receives a lever for assisting a connection to the mating connector. An upwardly open groove extends along an arrangement direction of the connector fitting receptacles and is provided behind the lever accommodating receptacle in a connecting direction to the mating connector. A hole is provided on a bottom part of the groove and communicates with a clearance between adjacent connector fitting receptacles.

Abstract: A mounting portion (20) of a housing (10) is to be inserted into a circular mounting hole (2) formed on a circuit board (1) and has a fixed piece (21) and two resilient locking pieces (30) at substantially equal angular intervals. The fixed piece (21) has an arcuate outer surface (22A). Each resilient locking piece (30) has a displaceable main body (31) with an arcuate outer shape (33A) that conforms to the inner peripheral surface of the mounting hole (2). A lock (37) is on a tip of the main body (31) and can be locked to an edge on an under side of the mounting hole (2). An extending portion (33) is formed on each of side edges of the main body (31) and extends circumferentially toward the fixed piece (21).

Abstract: A lever-type connector of the present invention includes a female housing (11), a lever (30) rotatably mounted on the female housing (11) and rotatable between an initial position and a connection position, a male housing (51) including a connector fitting portion (53) into which the female housing (11) is fittable and a lever fitting portion (54) into which the lever (30) is fittable, both the connector fitting portion (53) and the lever fitting portion (54) being open in the same direction, and a lock projection (56) provided in the lever fitting portion (54) and configured to hold the lever (30) fitted into the lever fitting portion (54) at the connection position.

Abstract: A decladding device of spent nuclear fuel easily and efficiently removes fuel pins from the spent nuclear fuel. Spent nuclear fuel pins P, made of austenitic stainless steel, and in which the spent nuclear fuel is filled, are fed by a feeder 7 one by one or by a unit of several pins and finely sheared into fragments by a shredder 1 having plural rotating blades 4, 5 so that fragments are of a size of 1 to 2 mm or less. The sheared fragments are separated into a fuel pin portion and a nuclear fuel portion by a magnetic separator 20. The magnetic separator 20 comprises a vibration feeder 27 feeding the sheared fragments and is arranged below the shredder 1. Without using a dissolving liquid of nitric acid, decladding is done and the spent nuclear fuel can be efficiently obtained.

Abstract: In reactor water control for a BWR power plant during an operation cycle after loading new fuel rods in the BWR power plant, an operation is performed which accelerates deposition of crud on the fuel rods until the deposition amount of the crud on the fuel rods reaches a predetermined target value within the operation cycle concerned. After the deposition amount of the crud has reached the predetermined target value, the crud deposition accelerating operation is terminated, whereby even when loading new fuel rods such as Zr liner type fuel rods having a surface on which metal ion deposition has been difficult, radioactivity in the reactor water is efficiently reduced.
