Abstract: A battery adapter for adapting a large capacity battery to a hand phone so as to supply power thereto in the case that the power of the hand phone battery is insufficient and it is impossible to charge the battery. The battery adapter includes an adapter and an imitative battery. The adapter has a mating face for mating with a large capacity battery. The mating face is disposed with more than one set of positive and negative electrodes connected to a lead wire. The lead wire extends from one side of the adapter to the imitative battery. The imitative battery has a shape similar to that of the battery for the hand phone and a mating face for mating with the hand phone. The mating face is disposed with several power terminals connected to the lead wire. When used, the large capacity battery is engaged on the mating face of the adapter and the imitative battery is engaged on the mating face of the hand phone so that the large capacity battery can supply power to the hand phone for long term of use.

Abstract: A device for receiving earphone/microphone wire of holdfree hand set, including a housing, a winding set and an earphone/microphone wire. The winding set is received in the housing. The winding set includes a lower reel and an upper reel for winding the earphone/microphone wire thereon without tangling or missing.

Abstract: A detachable clip assembly has a clip member which is removably engaged with a securing seat fixed to the back of a pager, a remote controller, a cell phone and a leather pocket etc. The securing seat has a positioning hole at the upper portion thereof. The clip member has a spring biased push plate on which a press button having a projected rib is disposed. The push plate is inserted into the securing seat with the projected rib engaged with the positioning hole for locking purpose. The press button can be actuated to get the projected rib to engaged with or disengaged from the positioning hole so that the clip member can be either removed from the securing seat or secured to the same as one desires.

Abstract: A back clip structure for a mobile phone, including a main body, a clip member and a stand. The main body is formed with a restricting seat and an engaging slot for fitting with the clip member. The clip member has a first face formed with an inner recess for placing the stand therein and a second face disposed with a support arm for inserting into the restricting seat of the main body. A row of tooth blocks are disposed on the surface of the inner recess for engaging with the stand. The stand is placed in the inner recess of the clip member to support the mobile phone in an upright state. The stand is slidable along the slide channels for height adjustment. When used with a mobile phone case, the main body is disassembled from the clip member, permitting the mobile phone to be fitted into the mobile phone case. The main body and the clip member have the same height so that the charging operation will not be affected.

Abstract: An improved electric plug for automobile use is equipped with an extra extension cord sticking out of a side hole; and a cord fixing hook disposed at the periphery of the top end of the plug body; and a socket disposed at the top end of the plug body so as to permit another plug to be coupled thereto consecutively. The extension cord can be adjustably wound around the plug body with the cord retained by the cord fixing hook, permitting the length of the cord to be varied to meet different requirement in use.

Abstract: The invention is directed to a tape cassette winder/rewinder adapted to wind on rewinder a conventional VHS tape cassette or a compact VHS-C type cassette. This is achieved by providing a space to receive the conventional VHS tape cassette and a recess below this space to house retractable confining arms that extend to hold a VHS-C tape cassette. The recess also houses a retractable idle gear assembly which extends to drive the take up reel of the VHS-C cassette when it is being held by the confining arms.

Abstract: A drive mechanism and control means for a bi-directionally operable 8-mm-video tape winding device which includes an electric circuit for actuating a motor to drive gears engaging a rack member pivotally attached to the underside of a slide board which, through cooperating means, permits starting winding before the winding direction is set and which further includes a clutch device associated with control buttons and tension sensing means to control the winding speed and direction of the tape winding device.
