摘要： In a coaxial connector, signal lines are switched over by mounting and dismounting a probe having a central contact, and fixed yoke terminals, a movable terminal, and a permanent magnet constitute a magnetic circuit. When the probe is dismounted, the contact portions are connected by the magnetic force of the permanent magnet. When the probe is mounted, the contact portions are disconnected against the magnetic force such that the central contact pushes a protrusion portion of the movable terminal.

摘要： 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.

摘要： An electronic component, a coaxial connector, and a communication device each have a structure wherein flux does not intrude into the components thereof during mounting. The coaxial connector includes a synthetic resin case divided into a lower-side insulative case and an upper-side insulative case, and a fixed terminal, a movable terminal, and an external terminal each being made of metal. The lower-side insulative case has two notches provided therein. One of the notches receives the lead potion of the fixed terminal, and the other of the notches receives the lead potion of the movable terminal. These notches are configured such that clearances are provided to prevent capillary effect from occurring between the lead portions of the respective two terminals and the lower-side insulative case.

摘要： An antenna-integrated strip line cable with which it is possible to improve the performance of a high-frequency appliance such as a portable telephone without making the appliance larger. An antenna-integrated strip line cable 1 is made up of a transmission line part 2, an antenna part 3 and a counterpoise 4. The transmission line part 2 is made up of two conductors 21, 22 disposed in parallel, insulators 23, 24 having plasticity or flexibility disposed between these two conductors 21, 22, and a central conductor 25 disposed between the insulators 23, 24 centrally in the width direction thereof. Wide-pattern impedance matching circuits 26a, 26b are provided in the central conductor 25. The antenna part 3 has portions of the insulator 24 and the central conductor 25 extending from the transmission line part 2. The counterpoise 4 has portions of the insulator 23 and the conductor 21 extending from the transmission line part 2. The counterpoise 4 is perpendicular to the antenna part 3 and the length of the counterpoise 4 is about one-fourth of the wavelength .lambda. of the frequency used. Some benefits of this novel construction are that the number of parts is reduced, the work of connecting a coaxial cable to an antenna is made unnecessary, the counterpoise reduces directivity of the antenna part, the antenna is tough, and it is not necessary to provide an impedance matching circuit externally.

摘要： 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.

摘要： 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.
