Abstract: A solid titanium catalyst component (I) for olefin polymer production contains titanium, magnesium, halogen, and a cyclic multiple-ester-group-containing compound (a) represented by the formula (1). Preferably, a propylene polymer that is obtained by the olefin polymerization method and has specific thermal properties as determined primarily by differential scanning calorimetry (DSC).

Abstract: A wireless network controller according to an embodiment includes multiple base stations, having multiple wireless channels including wireless channels having different communication rates, for carrying out wireless communication with communication terminals using the wireless channels. The wireless network controller controls a base station communicating with the communication terminal before movement and a movement destination base station for a new communication when the communication terminal is required to communicate with another base station.

Abstract: A resource seizure failure and a delay time in resource seizure are prevented from occurring when a packet transmit request is made, during a connected voice call, from a mobile station to which a multicall service is provided. When setting up a CS call, a resource for a PS call is reserved. When a PS call request is made by the user, the PS call is set up by using the reserved resource.

Abstract: An incoming call radio distributing apparatus provided in a communication system to distribute incoming calls to radio stations, which has a receiving station selecting unit selecting an available operator radio station for an incoming call among a plurality of operator radio stations for responding to incoming calls on the basis of states of communication of the plural operator radio stations, and an incoming call distributing unit preferentially connecting the incoming call to an operator radio station selected by the selecting unit. It is thereby possible to configure a mobile call center employing a mobile station as an operator station, provide station communications where calls are difficult to be disconnected, and high communication quality, a wide transmission band are available, and realize operator work not bound to a specific place.

Abstract: Disclosed herein is an adhesive composition which contains specific amounts of (A) an aqueous emulsion, (B) a filler and (C) a resin solution of a resinous tackifier dissolved in a solvent and/or plasticizer. The adhesive composition has a fast setting time in adhesion strength and excellent water-proofness and hence produces superb adhesion force even when applied to a fresh mortar base which has been aged insufficiently.
