摘要： A speaker driver is operated by a battery and drives a speaker to generate an alert tone in response to an externally input intermittent signal. The speaker driver includes a reference voltage generator for generating a reference voltage, a transconductance amplifier for outputting a current corresponding to a differential voltage between a voltage of the battery and the reference voltage, an output control switch for ON/OFF-controlling the output current from the transconductance amplifier in accordance with the intermittent signal, and a DC amplifier for amplifying the ON/OFF-controlled output current as a driving current for the speaker. Since a speaker driving current is decreased as a power source voltage is dropped, an abnormal voltage drop during an alert generation period can be prevented, thereby prolonging the service life of a battery.

摘要： An antenna having an antenna aperture area and an antenna reactance comprises a first antenna element (31) defining a first aperture area and a first reactance and a second antenna element (32) connected in parallel to the first antenna element to put a miniature radio receiver into operation in a desired frequency band. The second antenna element has a second aperture area and a second reactance greater than the first aperture area and reactance, respectively, so that the antenna aperture area and reactance are substantially determined by the second aperture area and the first reactance, respectively. The first and the second aperture areas may be coplanar. Alternatively, the aperture areas may be orthogonal to each other.

摘要： A radio paging receiver uses a receiver section for receiving and demodulating paging signals. A decoder section decodes the paging signals and a tone is generated in response thereto. When the center of slide switch is in normal position, the tone signals are rectified by a diode and applied to a speaker in order to generate subscriber alert tones. When the center of slide switch is in vibration position, the speaker does not generate any audible tones while a rectifier-integrator section is turned on to rectify and integrate the tone signals. The rectified and integrated tone signals activate a mechanical vibrator to tactilely inform the subscriber that he is being paged. The decoder section has a common output terminal for both the audible alert and the tactile vibration alert.

摘要： A kneader/stirrer includes two rotary shafts extending parallel to each other in the processing chamber, and first and second regular triangular impellers mounted to the respective rotary shafts. The first impellers are located at the same axial positions as the respective first impellers. The impellers are fixed to the respective rotary shafts at points offset from the centers of the respective impellers in a predetermined direction by a predetermined distance such that when the two rotary shafts rotate in the same direction at the same speed, each pair of first and second impellers are eccentrically pivoted, with one apex of one of the pair of impellers kept in contact with or in close proximity to the contour of the other impeller, thereby scraping off polycondensation resin (material to be processed) adhered to the other impeller.
