Abstract: A connector device comprises a connector and a mating connector. The connector is mateable with the mating connector and removable from the mating connector. The mating connector includes a mating primary terminal and a mating secondary terminal. The connector includes a housing, a sub-connector, a first operation member and a second operation member. The housing holds a primary terminal while the sub-connector holds a secondary terminal. When the first operation member is operated, the housing is moved, and the primary terminal is connected to the mating primary terminal. When the second operation member is operated, the sub-connector is moved, and the secondary terminal is connected to the mating secondary terminal.

Abstract: A connector device comprises a connector and a mating connector connectable with each other. The mating connector comprises a mating primary terminal and a mating secondary terminal. The connector comprises a primary terminal, a secondary terminal, an operation member and a push-back mechanism. The operation member changes its state from an initial state to a second state via a second state. When the state of the operation member is changed to the first state, the primary terminal is connected to the mating primary terminal. When the state of the operation member is changed to the second state, the secondary terminal is connected to the mating secondary terminal. When the state of the operation member is changed to the first state, the push-back mechanism applies a push-back force to the operation member to change the state of the operation member back toward the initial state.

Abstract: A contact increased in contact reliability by accommodating misalignment from a mating contact. A female-side contact includes a contact body including a contact portion that is brought into contact with a mating contact portion of a male-side contact, and a supporting member formed separate from the contact body, for receiving therein the mating contact portion and movably supporting the contact portion. The supporting member includes a supporting member body for receiving therein the mating contact portion and the contact portion, and first and second spring portions provided on the supporting member body, for bringing the mating contact portion inserted in the supporting member body and the contact portion into contact with each other. The contact portion includes a contact portion body having a flat plate shape and contact point portions protruding from the contact portion body into the inside of the supporting member body.

Abstract: A railcar includes a heat-resistant floor, and the heat-resistant floor includes a floor panel, a heat absorbing layer provided under the floor panel and configured to absorb heat, and a supporting plate configured to support the heat absorbing layer from below. The supporting plate includes contacting portions each configured to contact the heat absorbing layer and separated portions each continuously formed from the contacting portion in a railcar width direction, separated downward from the heat absorbing layer, and extending in a railcar longitudinal direction.

Abstract: A connector is receivable an object along a receiving direction. The connector ejects the object along an ejecting direction opposite to the receiving direction. The object has a mating terminal, a pressed portion and a regulated portion. The connector comprises a holding member, a terminal and an operation member. The operation member is supported by the holding member so as to be movable between a first position and a second position. The operation member includes a press portion and a regulating portion. When the operation member is operated to be moved from the first position toward the second position, the press portion presses the pressed portion in the ejecting direction to move the object in the ejecting direction.

Abstract: Provided is a floor structure of a railcar in which thickness of a heat insulating material can be reduced while having predetermined heat resistance. The floor structure of the railcar includes a underframe having a pair of side sills extending in a railcar longitudinal direction and a cross beam arranged between the side sills and extending in a railcar width direction, a structural floor provided on an upper surface of the underframe, and a first heat insulating material arranged on a lower side of the structural floor via an air layer for the structural floor.

Abstract: An underframe structure of a railcar capable of reducing a deformation amount of a cross beam supporting an underfloor equipment upon underfloor fire. The underframe structure of the railcar includes an underframe having a pair of side sills extending in a railcar longitudinal direction and a cross beam arranged between the side sills and extending in a railcar width direction, a structural floor provided on an upper surface of the underframe, and an underfloor equipment suspended down in a center part in the railcar width direction of the cross beam. The underframe structure includes a passenger cabin floor provided on an upper side of the structural floor, the passenger cabin floor forming a lower surface of a passenger cabin S, and floor receiving members supporting the passenger cabin floor and extending in the railcar longitudinal direction between the structural floor and the passenger cabin floor.

Abstract: (1) Monolithic ceramic filter having a portion of the partition wall of a honeycomb structure exposed with its end face on an outer wall surface 13 of the structure and increased in thickness as compared to the remaining portion of the partition wall to form a flow resistance relaxing portion 12.

Abstract: A monolithic ceramic filter having a portion of the partition wall of a honeycomb structure exposed with its end face on an outer wall surface of the structure and increased in thickness as compared to the remaining portion of the partition wall to form a flow resistance relaxing portion is disclosed. The monolithic ceramic filter may also have a groove-shaped recess which is separated via a partition from a liquid supply passage of a honeycomb structure and is in communication with the outside of the structure. The flow resistance of the filtrate within the partition walls may be diminished to enable efficient filtration. The filter is produced simply by extrusion molding. There is no necessity of forming holes for discharging the filtrate in some cases.
