Abstract: A mobile communication method for a mobile originating (MO) side communicating with a mobile terminating (MT) side is disclosed. A first media gateway (MGW) is included in the communication network serving the MO side, and a second MGW is included in the communication network serving the MT side. The mobile communication method includes: after a SETUP message is received from the mobile originating side, determining if the mobile originating side is in Circuit Switching (CS) Domain. If the MO side is under CS domain, determining if the MT side is under CS domain. When the MO side and the MT side are both under CS domain, voice communication signals between the MO side and the MT side are transmitted with CS bearer between the first MGW and the second MGW.

Abstract: A compact disk receiving device includes a base having a plurality of engaging members extending from a surface of the base and the engaging members are arranged as a circle. At least two of the engaging members each have at least two protrusions extending from an outer periphery thereof and the at least two protrusions are located at different distances from the surface of the base. At least two compact disks are mounted to the engaging members and are separated by the at least two protrusions.

Abstract: A speaker case includes a first part and a second part connected to the first part. Each of the first part and the second part has a recess defined in each sidewall thereof and the two recesses are cooperated to define a hole through the case. A connector includes a tubular body with grooves defined in the outer periphery thereof so that the sidewalls of the first part and the second part a first case are engaged with one groove, and the sidewalls of a second case are engaged with the other groove so that the two speaker cases are combined together. The connector may have a close end, an enlarged end or a threaded inside so as to have further functions.

Abstract: A compact disk receiving device includes a cover, a base pivotably connected to the cover, and a support plate located between the cover and the base. A shaft is rotatably engaged between two first lugs extending from a side of the cover. The shaft has a first hook member and the support plate has a second hook member which is engageable with the first hook member so that the support plate is able to be slid between the cover and the base. An opposite side of the side having the first hook member is an open side so that two shafts can be piled up by inserting the first hook member of one shaft into the open side of the other shaft.

Abstract: A speaker assembly includes two housing and two couplers secured in the housings. One of the couplers includes a bore and the other coupler includes an extension for engaging with the bore so as to secure the couplers and the housing together. One of the couplers includes a curved slot and the other coupler includes a projection for engaging with the curved slot so as to limit the rotational movement between the couplers. The couplers each includes a bore for engaging with a wire or a connecting line. A number of housings may be secured together so as to form a speaker wall.

Abstract: An apparatus for collecting roll films to be developed includes a housing having an opening formed in the front portion. A barrel is rotatably supported in the housing and has an orifice for aligning with the opening and for allowing insertion of the roll film into the barrel. The barrel may enclose the opening when the orifice is disengaged from the opening. The housing includes a pair of channels for guiding a roller and the barrel to move up and down. A roll of strip material is supported in the housing and has an end engaged between the roller and the barrel so as to be sent out of the housing via a slit.

Abstract: A speaker housing combination includes two side plates each having two strips extended from the upper and the lower portions so-as to form two channels and each having two shoulders formed in the front and the rear portions. A top and a bottom plate each has two flanges extended from the side portions for engaging with the channels and each has a shoulder formed in the front and the rear portion. A front and a rear plates each has the edges engaged with the shoulders so as to be solidly secured to the top and the bottom plates and the side plates. The top and the bottom plates may further be secured together by fastening members. The plates may be easily assembled by the users and may be stored in a compact volume which is excellent for storing and for transportation purposes.
