Abstract: This linear motor drive device includes: a stator on which a plurality of coils connected in series are disposed to be arrayed; a plurality of half-bridges; and a switching controller including a half-bridge output voltage calculator. Both ends of a series unit of the coils and connection points between the coils are each connected to an output point of a different one of the half-bridges. AC voltages are applied to the respective coils. The half-bridge output voltage calculator obtains, through calculation, output voltage references for the respective half-bridges on the basis of application voltage references for voltages to be applied to the respective coils. The switching controller obtains switching signals for controlling switches of the half-bridges by using the respective half-bridge output voltage references having been obtained.

Abstract: A printed wiring board includes: a first insulating layer having a first surface and a second surface opposite from the first surface; a second insulating layer stacked on the first surface of the first insulating layer; and a conductor wiring interposed between the first insulating layer and the second insulating layer. The first insulating layer contains a liquid crystal polymer. The second insulating layer contains a cured product of a thermosetting composition, containing an inorganic filler and a thermosetting component, and a fibrous base member. A temperature, at which a decrease in the mass of the second insulating layer that has had its temperature increased at a temperature increase rate of 10° C./min from an initial-state temperature of 25° C. reaches 5% of its initial-state mass, is equal to or higher than 355° C.

Abstract: Disclosed is a mobile communication system including a network constituted of at least one switching center and a plurality of base stations, and a mobile station which communicates with the base stations simultaneously. The system permits varying transmission delay between the switching center and the base stations according to the type of services available to the mobile station. The object of the present invention is to propose a communication which permits varying transmission delay according to the type of service currently employed, and to promptly recover a synchronization state even if an out-of-sync state happens. To attain the object, a memory means (mobile switching center processor 32) stores transmission delay characteristics corresponding to services which are available to the mobile station.

Abstract: A spreading and/or despreading mechanism in which the inphase component and a quadrature component of a signal are to be transmitted by using a short code and a long code. The long code has an inphase component and a quadrature component that are different from each other. The spreading and despreading operations carry out a complex-to-complex operation between a combination of the inphase component and the quadrature component of the signal and a combination of the inphase component and the quadrature component of the long code.
