Further, the present invention is: a hydride composite containing NaH, a metal salt containing an alkali earth metal or a transition metal, and an ammonia source that is a solid at ordinary temperatures and generates an ammonia gas by decomposition; and a preparation process of a hydrogen gas including a reaction process to heat such a hydride composite.

Abstract: There is provided a process for producing an energy gas at a lower temperature and in a larger amount, as well as an energy gas storage material capable of easily taking out the energy gas. A process for producing an energy gas including a MG processing step of co-grinding a mixture of a carbon-, hydrogen-, and oxygen-containing compound, an alkali metal or compound thereof, and an alkaline earth metal or a compound thereof, thereby obtaining a MG processing product and a heating step of heating the MG processing product in an inert atmosphere, as well as an energy storage material obtained by the MG processing described above. The MG processing step preferably including adding a transition metal or a compound thereof to the mixture and co-grinding the mixture.

Abstract: A complete locking confirming device for an electric connector comprising a first connector having a first connector housing, a second connector having a second connector housing capable of being coupled with the first connector housing, and locking means provided in combination with the first and second connector housings to lock the electric connector when the first and second connectors are coupled completely. The complete locking confirming device comprises a complete locking detecting slider mounted on either of the first connector housing and the second connector housing so as to be positioned at a complete locking indicating position only when the first and second connectors are coupled completely and the electric connector is locked by the locking means.

Abstract: An electric connector with a double locking mechanism for connecting the electrical conductors of electric circuits on a vehicle. The electric connector with a double locking mechanism comprises a male connector provided with a locking arm having a locking projection, a female connector housing provided with a slot for receiving the locking projection of the locking arm for primary locking when the male connector housing and the female connector housing are joined perfectly together, a locking slider mounted on the female connector housing for sliding movement toward and away from the male connector housing between a first position and a second position, and a spring basing the locking slider to the releasing position. When the male and female connector housings are joined perfectly together, the locking projection is received in the slot of the female connector housing and engages the female connector housing for primary locking.

Abstract: A locking security mechanism for an electrical connector having a pair of male and female connector members, locking means and a locking security member mounted in a male connector member in a normally undetachable manner and maintained in a pre-engagement position with a pre-engagement releasing means in a female connector member. When the male and female connector members are engaged with each other, actuating fingers in the female connector member act on a inclined lower surface of pre-engagement fingers in the locking security member to escape the pre-engagement.

When the male and female connector members are engaged with each other, actuating fingers in the female member act on a inclined lower surface of pre-engagement fingers in the locking security member to escape the pre-engagement.

Abstract: Described herein is a connector terminal retainer which is connectible to a rear portion of a connector housing to anchor terminal members in the respective terminal compartments in the connector housing. The terminal retainer is provided with; a pair of locking arms extending forward from opposite side walls of the terminal retainer body for engagement in socket portions in the connector housing, and constituted by a pair of vertical resilient portions extending parallely on opposite sides of a gap space formed in the longitudinal direction of the arm and a horizontal resilient portion extending over and along the gap space on the outer side of the vertical resilient portions; and provisional and main locking projection provided in longitudinally shifted positions on the vertical and horizontal resilient portions of the locking arms of interlocking engagement with corresponding jocking portions in the socket portions of the connector housing.

Abstract: Disclosed herein is a connector which comprises a female housing and a male housing to be fitted to said female housing for electrical connection therebetween. The connector has a locking structure including a locking arm having a locking edge portion provided on one of the housings and a locking projection provided on the other housing. The locking arm is flexibly supported on either the female or male housing and the locking projection is provided so as to be locked with the locking edge portion when the female and male housings are properly fitted together. The locking projection is constructed so as to camber the locking arm when the male housing is inserted into the female housing, thereby causing a restoring force to be generated in the locking arm. Further, the locking structure includes a member for increasing the restoring force to secure the fitting between the locking edge portion and locking projection without increasing the force required to disengage the locking structure.

Abstract: A waterproof electrical connector. The waterproof electrical connector is comprised of a male connector housing and the female connector housing. The male connector housing has an annular enclosure around an outer periphery thereof to form an annular cavity therebetween. A seal ring is inserted into the annular cavity. The above-mentioned seal ring has a first section of smaller wall thickness to leave a space, when inserted into the cavity, forwardly opening and a second section of larger wall thickness extending rearwardly of said first section to resiliently press fit the annular enclosure, the end wall and the outer periphery. The female connector housing has a sleeve formed forwardly of an outer periphery thereof and adapted to be inserted into said space. Due to the existence of the second section of larger wall thickness in the seal ring, the turning over thereof which takes place at the time of engaging and disengaging the prior art waterproof connector is prevented.

Abstract: Disclosed herein is a connector which comprises a female housing and a male housing to be inserted and fitted into the female housing for establishing electrical connection therebetween. A flexible locking arm having a locking aperture is provided on either the male or female housing, and a locking projection is provided on the other housing for generating a restoring force in the locking arm by cambering the locking arm when the male housing is inserted into the female housing. The locking projection engages with the locking aperture by the restoring force in the locking arm when the male and female housings are properly fitted together. The connector further comprises a member provided on the locking arm for producing a fitting-confirmation sound by the restoring force in the locking arm when the locking projection becomes engaged with the locking aperture.
