摘要： A battery charger for a portable wireless telephone set comprising a rapidly charging circuit for rapidly charging the battery by a first charging current of a high level at a start of the charging operation, a tricklingly charging circuit for tricklingly charging the battery by a second charging current of a considerably low level, and a charge controller for making the tricklingly charging circuit take over the rapidly charging circuit after a charge detecting circuit detects that the battery is rapidly charged to its normal voltage. In order to avoid that the battery is insufficiently charged by the tricklingly charging circuit when the telephone set is left in a power-on condition, the battery charger further comprises another charging circuit for supplying a third charging current which is lower thn the first charging current but higher than the second charging current. When the telephone set is in the power-on condition, the charge controller operates not the tricklingly charging circuit but the other charging circuit after the battery is rapidly charged to its normal voltage, so that the battery can be charged to the normal voltage even if the telephone set is left in the power-on condition.

摘要： A mechanical filter having at least a pair of mechanical vibrators which are arrayed approximately in parallel with each other in regard to their longitudinal axes, and two couplers which are coupled to the pair of mechanical vibrators. According to the mechanical filter one of the pair of mechanical vibrators undergoes the vibration of the order of an odd number and the other one undergoes the vibration of the order of an even number in the same vibration mode, or both of them undergo the vibration of the order of an odd number or even number in the same vibration mode. Furthermore, these mechanical vibrators have such a mechanical size that they will vibrate at their required order of vibration and at their respective resonance frequencies, and the two couplers are so constructed that they will be differentially coupled to the pair of mechanical vibrators approximately at right angles therewith.

摘要： A method for automatic frequency adjustment of mechanical resonators, in which plural target frequencies are specified spaced across the distribution curve of the initial resonance frequencies of the mechanical resonators; an output quota for finished resonators is specified at each target frequency; the initial resonance frequency of each resonator is measured, and the resonator is then transferred to an automatic trimming machine; and the adjusting frequency of the automatic trimming machine is reset, for that particular resonator, to the particular one of the target frequencies which is next higher than the initial resonance frequency of the mechanical resonator. However, if the output quota for that target frequency has already been filled, a still higher target frequency is specified instead. If the output quotas have been filled for all target frequencies within a permissible adjustment range, then the resonator is returned for coarse adjustment. Additionally, the resonance frequency of the resonator may be monitored during the adjustment process in the trimming machine, and, if the resonance frequency of the resonator rises above the target frequency by more than a permissible margin of error during the trimming process, the resonator is recycled to be readjusted by the same process to a higher target frequency.

摘要： An electromechanical filter having minimum attenuation deviation in the pass band frequency range. The filter includes a plurality of mechanical resonators arranged substantially parallel to each other in one plane and mechanical couplers of longitudinal resonance characteristics which are disposed substantially transverse to the plurality of resonators for coupling the resonators together. The couplers have lengths which are between the first and second, and second and third oscillation modes of the longitudinal resonance characteristics. By virtue of the above structure, the couplers can be formed in a single mechanical coupling wire.

摘要： A radio transceiver comprises an RF amplifier and a first frequency mixer which converts an amplified RF signal into a first IF signal and whose output may include intermodulation distortion. A second frequency mixer converts the output of first frequency mixer into a second IF signal. An interference detector detects the intermodulation distortion by seeing if a beat is included in the second IF signal. Upon detection of intermodulation distortion, a controller minimizes a gain of RF amplifier to decrease or eliminate the intermodulation distortion. Responsive to the end of conversation, the controller maximizes the gain of RF amplifier to increase the reception sensitivity. The controller may periodically maximize the RF amplifier gain after the detection of the intermodulation distortion. If no intermodulation distortion is detected during this gain-maximized period, the controller keeps the gain to be a maximized value. If the intermodulation distortion is not decreased or eliminated even though the RF amplifier gain is minimized, the controller may change a used frequency to another frequency.

摘要： A mechanical filter including at least two longitudinal mode vibrators, each of which is a piezoelectric ceramic member with constant modulus alloy members mounted separately on the top and bottom surfaces thereof. The two constant modulus alloy members have the same configuration, a frequency-temperature characteristic opposite to that of the piezoelectric ceramic member, and are aligned, at their individual centers, with the center of the piezoelectric ceramic member. The configurations of the two longitudinal mode vibrators can be predetermined to suppress higher order spurious vibration modes inside the mechanical filter itself.

摘要： A flexural electromechanical transducer composed of a constant-modulus alloy material and a piezoelectric ceramic material having a high electromechanical coupling coefficient. In the transducer, the piezoelectric ceramic material is polarized in one direction and a specified frequency signal is applied to the piezoelectric ceramic material in a direction parallel to the residual polarization direction of the piezoelectric material for obtaining a thickness-shear vibration. The thickness-shear vibration of the piezoelectric material in turn causes the flexural vibration of the transducer. The transducer achieves a high quality factor Q, a low capacitance ratio r, good spurious characteristics, and low impedance.
