摘要:
A radio telephone switching control system having control channels which transmit/receive control data betweeen a plurality of movable terminals and a radio base station. The control channels include a mono-functional channel for access which is dedicated to access during data transmission/receiving by calling from the terminals. The control channel also includes a bi-functional channel for paging and access usable as a channel for paging one of the terminals as well as for access. The system contains a base station with a fault detector. Only one kind of control channel information is broadcast in the same service zone. All of the movable stations existing in same service zone scan the first or second range to decide the channel for access or paging according to the received control channel information. The system also sets the mono-functional channel for access and the bi-functional channel for paging and access, when a fault is not detected. Once a fault is detected, the second range is separated from the first range, whereby the mono-functional channel for paging is used only to transmit data for paging from the base station and the mono-functional channel for access is used to transmit/receive data related to actions other than paging to the terminals.

A printed circuit board laminator adapted for laminating a film on the surfaces of the baseboards of printed circuit boards. The laminator comprises a laminating mechanism which can continuously laminate a long film on the continuously fed baseboards. The laminator comprises a constant-gap baseboard feed mechanism, which can arrange the baseboards with a constant gap therebetween, and continuously feed them to the laminating mechanism. The laminator further comprises an access hole-making unit which can make access holes in the film to be aligned with indexing holes in the baseboards, prior to the lamination. The laminator also comprises a cutting mechanism which can cut the film laminated to the boards for separating the latter from each other.

An audio reproduction device and system are capable of realizing sounds having natural sound quality with no peculiarities, and provide an excellent audio-image ascending effect which is not varied due to differences among individual persons, thereby making audio images and images coincident with each other. A frequency characteristic correction portion forms a frequency characteristic such that a sound-pressure frequency characteristic of reproduced sound radiated to a viewing position from speakers has a first peak and a second peak, wherein the center frequency of the first peak falls within the range of 6 kHz±15%, and the center frequency of the second peak falls within the range of 13 kHz±20%.

An acoustic reproduction device includes first speaker units 12 and 15 that emit sound in an inward direction and second speaker units 13 and 16 that emit sound in a forward or outward direction. The first speaker units are arranged at positions symmetrical with respect to a listening center axis, and so are second speaker units. The device further includes first and second processing units that process center channel signals as signals for the first and the second speaker units, respectively. Front channel signals are superimposed on an output signal of the second processing unit. The first processing unit includes a HPF 33 and a first high-shelf block 34 for boosting a high-range component. The second processing unit includes an LPF 38, a low-shelf block 36 for attenuating a low-range component, and a second high-shelf block 37 for attenuating a high-range component. Center channel reproduction sounds arriving from the first speaker unit and the second speaker unit that are closer to a listening position are destructive to each other in the mid-range owing to a phase difference therebetween. It is possible to expand a listening position range where the center sound image localization can be achieved, and to integrate a center speaker into a front speaker system.

In a method of manufacturing a Josephson junction, a first superconductive layer is formed on a substrate. An insulating film is formed on the first superconductive layer. The insulating film is etched to have an inclination portion. The first superconductive layer is etched using the etched insulating film as a mask, to have an inclination portion. A barrier layer is formed on a surface of the inclination portion of the first superconductive layer. A second superconductive layer is formed on the barrier layer and the inclination portion of the insulating layer.
