Abstract: Provided is a mobile terminal that communicates with a server that performs call control between an intercom disposed in a lobby of an apartment building and an indoor monitor. The server stores event information transmitted from the intercom, the indoor monitor, or a terminal apparatus connected to the server. The mobile terminal includes: a receiver that receives the event information from the server; and a display section that displays the event information in chronological order from an upper side to a lower side of a display apparatus and that scroll displays the event information.

Abstract: A linear motor heat dissipation structure including multiple teeth arranged linearly at predetermined intervals each with coil wound around rectangular tube-shaped bobbin, and heat dissipation member provided between adjacent coils that dissipates heat generated coils by transmitting the heat to an external section. Heat dissipation member is sandwiched by bowed sections of coils that are curved outwards within edges of rectangular tube-shaped bobbin due to elastic force of coils. Accordingly, even when there are component tolerances and assembly tolerances, those tolerances are absorbed by the elastic deformation of the bowed section of coils such that the variance in the contact state between coil and heat dissipation member is made smaller so that stable and high heat dissipation performance is achieved.

Abstract: A linear motor device comprising: a path member including a magnet extending in a movement direction; and a moving body including a coil that is movably mounted on the path member; the linear motor device generates thrust in the movement direction between the magnet and the coil by current being passed through the coil; the moving body further includes a magnetic shielding target object, and a magnetic shielding member formed from strongly magnetic material that shields the magnetic shielding target. The magnetic shielding member includes a parallel shielding plate provided parallel to the movement direction between the magnetic shielding target object and the magnet, and a perpendicular shielding plate provided extending away from the magnet in a direction perpendicular to the movement direction at at least one of a front edge and a rear edge of the parallel shielding plate in the movement direction.

Abstract: Extruded polymer foams are made from a polymer composition that includes an unbrominated styrenic polymer, a brominated vinyl aromatic/butadiene flame retardant, and an unbrominated vinyl aromatic/butadiene polymer. The unbrominated vinyl aromatic/butadiene polymer improves the cell homogeneity.

Abstract: A cordless base unit includes a controller that performs control in a case where an incoming call arrives from the landline telephone network, in such a manner that the cordless handset and the mobile information terminal perform sound ringing for the incoming call, that automatic answering starts after a predetermined time has elapsed and the sound ringing for the incoming call is stopped except for the mobile information terminal that is set to be used outside of the house, and that while the automatic answering is performed, the mobile information terminal that is set to be used outside of the house continues to perform the sound ringing for the incoming call.

Abstract: An automatic telephone answering apparatus sends an out-going message recorded in a memory through a telephone line and records in-coming messages in another in-coming message memory. In addition, the apparatus records a conversation between an operator and a partner. The apparatus includes a line status detector that detects the status of the telephone line and a controller that is responsive to the line status detector for effecting a predetermined preparation operation. The apparatus further includes a control mechanism for detecting an area of the in-coming message memory where in-coming messages are stored and detecting an empty area of the in-coming message memory. The controller effects the preparation operation by causing the control mechanism to detect the empty area.
