摘要:
A mobile communication system includes a switching unit, a plurality of radio base stations, and a mobile station. The switching unit processes a call from an originating terminal. The radio base stations have service areas allowing radio communication and are connected to the switching unit. The mobile station performs radio communication with the radio base station within the service area. The switching unit includes a switching section, a database, and a message forming section. The switching section performs switching/connection between the originating terminal and the mobile station on a terminating side through the radio base station. The database stores last registration time recognized by the mobile station. The message forming section forms a speech message including the last registration time stored in the database and outputting the message to the originating terminal when there is no response from the mobile station with respect to a terminating operation.
摘要:
A radiation imaging operation, wherein a radiation source irradiates radiation to an object, while the radiation source is being moved in one direction, is performed a plurality of times with the radiation source taking various different positions. A radiation detector is reciprocally moved within a period, during which the radiation source is moved in the one direction from a stage of beginning of the plurality of times of the radiation imaging operations to a stage of finishing of the plurality of times of the radiation imaging operations. The radiation detector is moved in a direction opposite to the one direction of the movement of the radiation source within each of radiation imaging operation periods.

Provided is an anti-vibration rubber member wherein there is low friction resistance between the anti-vibration rubber member and a mating member, and a coating film is not prone to separation from a rubber elastic body, and a production method thereof. An anti-vibration rubber member absorbs at least a portion of the vibration of a mating member and has a sliding surface that is relatively in sliding contact with the mating member. The anti-vibration rubber member further includes: a rubber elastic body that is made of a self-lubricating rubber containing an elastomer and a bleeding lubricant; a coating film that covers at least a portion of a sliding inner surface that is among a surface of the rubber elastic body and disposed on an inner side of the sliding surface, contains a resin having a mercapto group, and is deformable to follow up deformation of the rubber elastic body, and a lubricating film that covers at least a portion of a surface of the coating film, is formed by the bleeding lubricant of the rubber elastic body penetrating the coating film and oozing onto the surface of the coating film, and forms at least a portion of the sliding surface.

A smoke detector having a structure in which, at a time of performing smoke detection, an S/N ratio of a signal of a light receiving element is improved, to thereby accurately detect the occurrence of a fire. At opposite end portions of an inside of an optical case (21) having a substantially cylindrical shape, a light emitting element (11) and a stray light portion (22) are arranged. In the stray light portion (22), a light trap (23) is provided. Further, in the vicinity of the light emitting element (11), a condenser lens (24) is provided to allow light L to be incident on a curved surface of the light trap (23). At the time of smoke detection, light scattered by smoke particles in a smoke detection portion (25) is received by a light receiving element (12). However, the light that is incident on the light trap (23) is reflected on the curved surface a plurality of times to be attenuated in each reflection, so the light is not received by the light receiving element (12). Accordingly, the S/N ratio of an output signal S obtained from the light receiving element (12) is improved, thereby making it possible to accurately perform smoke detection at an early stage.
摘要:
A supporting/moving section for supporting and moving a device to predetermined positions at which radiation imaging is performed is prepared. An operating portion is provided for manipulating the movement of the device supported by the supporting/moving means. A detecting section outputs detection signals, which are obtained by detecting external forces which are applied to the operating portion. A control section controls the supporting/moving means to move the device such that the movement tracks target values for movement, which are determined from the detection signals. During manipulation of the operating portion, a unique oscillation frequency measuring section executes measurements to obtain a unique oscillation frequency of the device. A unique oscillation attenuating section attenuates signal components, which are included in control signals output by the control means to control the supporting/moving means and cause the movement of the device to fluctuate at the unique oscillation frequency, in real time.

In a shift lever, when a button of a knob is pressed, a link member is pivoted, and a detent rod is moved down. Further, impact sound or the like is restrained or prevented from being emitted by bringing the link member into contact with a contact member and elastically deforming the contact member. Here, a cover portion of the knob and the contact member are constituted by separate members. Therefore, the cover portion of the knob and the contact member can easily be constituted by materials suitable for respective functions.
