A coaxial microstripline transducer, having an inner conductor with a center conductor portion arranged in a recess portion of a resin case and a terminal portion which is integral with the center conductor portion and formed so as to lead to a lower surface of the resin case. An outer conductor has a first conductor portion arranged along at least a part of an inner peripheral surface of the recess portion and a second conductor portion which is integral with the first conductor portion and extended to the lower surface across an upper surface and across a pair of side surfaces opposed to each other of the resin case. The inner and outer conductors are fixed to the resin case. The outer conductor is preferably made of sheet metal material so as to enjoy low high-frequency losses. The first conductor portion advantageously is resilient and projects into the recess portion of the resin case to grip and engage a plug inserted into the transducer.

Paging data are more reliably RAKE-received, according to the present invention. A paging mode control method includes the steps of forming a delay profile, searching a path timing on the basis of the delay profile, and performing RAKE receiving on the basis of the path timing. The delay profile includes a first delay profile formed by a speech mode and a second delay profile formed by a paging mode, and a time range of the second profile is wider than a time range of the first profile. With the formation of the second profile, even when the measured paging cycle is not accurate, the paging data can be reliably RAKE-received. The time range of the second delay profile is made wide by connecting a plurality of delay profiles, or by lowering a resolution.

A movable terminal and a coaxial connector have greatly improved durability and have outstanding contact/connection reliability, and are included in a communication apparatus. A coaxial connector includes a two-split synthetic resin case having a lower insulating case and an upper insulating case, a metal fixed terminal, a movable terminal, and an external terminal. The movable terminal having a spring movable function includes a movable contact portion with which the fixed terminal makes contact, a fixed portion fit in the upper and lower insulating cases, and a lead portion bent in an L-shape. The movable contact portion has a frame-shaped portion, a spring movable portion upwardly curved in an arcuate shape, and a contact portion provided at the approximate center of the spring movable portion.

A coaxial connector is connected to a leading end of a coaxial cable and is detachably connected to a receptacle. The coaxial connector includes a cylindrical housing including a spring portion having a projection to be fitted in a groove provided on the outer periphery of an outer conductor of the receptacle, a central conductor probe stored in the housing so as to be in contact with an inner terminal of the receptacle, and cylindrical sleeves held on the outer periphery of the housing so as to be movable in the axial direction. The sleeve has lock pieces provided in an upper portion and an annular portion in a lower portion. The lock pieces are in elastic contact with a first engaging portion and a second engaging portion provided on the outer periphery of the housing. The annular portion restricts expansion of the spring portion of the housing. The annular portion of the sleeve does not restrict the spring portion when detached (position A), and restricts expansion of the spring portion when attached (position B).

The present invention is to provide a coaxial connector capable of achieving secure and stable contact and connection, and realizing sufficiently small size and thin shape. A movable terminal has a movable mechanism part formed so as to have a spring movable function and a lead part, linked with the movable mechanism part, applied with the bending process into a U-shape. The movable mechanism part comprises a base part elongating from the lead part to both sides, two spring supporting parts formed at both end parts of the base part, a spring movable part elongating parallel with the base part between the spring supporting parts, and a contacting part formed projecting from the spring movable part. The spring movable part is supported and fixed at both ends by the spring supporting parts so as to form an arc-like shape with the center part bulged upward, and thus the contacting part can contact with the lower surface of the contacting part of the fixed terminal by the force derived from the spring property of the arc-like spring mechanism so that the fixed terminal and the movable terminal are contacted and connected.

A digital filter circuit has two decimation filters, a first and a second, for performing two decimations with respect to a digital data of a predetermined sampling rate. The first decimation filter has a function of producing processing signals for a filter coefficient of the second decimation filter and providing such operational signal to the second decimation filter. Since the output of the first decimation filter is not a coded numeral value but is an output in the form of a processing signal for the filter coefficient of the second decimation filter, the first decimation filter can take the form of a decoder circuit and not an operational circuit and the second decimation filter can be simpler than that having a multiplier circuit of a conventional circuit. The scale of the overall circuit can be reduced and this contributes in the enhancement of high integration of large scale integrated circuits (LSIs), in the scaling down of chip areas and in reducing the manufacturing cost.
