摘要： To reduce the magnetic flux leakage through the gap between magnetic pole teeth of an armature so as to reduce the magnetic attraction force generated between the armature and a needle, an armature unit is provided with two magnetic poles, on the top of which are magnetic pole teeth protruding toward the opposing magnetic pole, where the magnetic pole teeth of the magnetic pole are arranged at two heights, upper and lower, and the magnetic pole teeth of the opposing magnetic pole are arranged at two heights, upper and lower, so that the magnetic flux flows upward and downward alternately between the upper and lower magnetic pole teeth. The needle equipped with permanent magnets moves relatively in the gap between the upper and lower magnetic pole surfaces of the armature unit.

摘要： For a plurality of digital video signals whose frame frequencies are different, a pixel number converting circuit to convert the number of pixels is provided so that differences of the frame frequencies are replaced to differences of the numbers of pixels and a plurality of digital video signals whose frame frequencies are different can be processed by a common clock frequency. The frame frequency is detected by a frame frequency value decoder and the number of pixels in the horizontal direction of the pixel number converting circuit is properly set in accordance with the frame frequency. As mentioned above, if the differences of the frame frequencies are replaced to the differences of the numbers of pixels and the images are converted into the image in which the frame frequencies are the same and the numbers of pixels are different, the frame frequencies are equalized and the signals can be processed by the same clock.

摘要： This invention relates to a apparatus and a method for allowing a digital broadcast receiver smoothly to switch from one broadcast channel to another. In response to a reproduction output request, encoded data that are requested to be reproduced and output are selected and decoded accordingly. At the same time, arrangements may be provided to select and decode other encoded data in accordance with a predetermined rule. Whenever the encoded data selected as per the predetermined rule are to be reproduced and output on request, conventionally required demultiplexing and decoding processes are not needed. This provides a significant reduction in channel select time.

摘要： Signal levels of received signals are detected within a plurality of different frequency bands by a first electric field strength detecting means 15 and a second electric field strength detecting means 16, then it is detected by an adjacent wave detecting means 17 based on this output signal whether or not adjacent waves are contained, then a filter controlling signal 19 is output to a first I low-pass filter 9a and a first Q low-pass filter 10a from a baseband filter controlling means 18 according to whether or not the adjacent waves are contained, whereby low-frequency cut-off frequencies of the first I low-pass filter 9a and a first Q low-pass filter 10a are switched and controlled. Accordingly, a receiving sensitivity can be improved by reducing an influence of an adjacent wave and a tolerance for frequency offset of an oscillation frequency of a local oscillator relative to a carrier frequency of a received signal can be enhanced.

摘要： A direct conversion receiver includes a local oscillator for generating a first local oscillator signal having a variable frequency. A 90° phase shifter operates for shifting a phase of the first local oscillator signal by 90° to convert the first local oscillator signal into a second local oscillator signal. A first mixer operates for mixing a received RF signal and the first local oscillator signal. A second mixer operates for mixing the received RF signal and the second local oscillator signal. A first low pass filter processes an output signal of the first mixer. The first low pass filter has a controllable cutoff frequency. A second low pass filter processes an output signal of the second mixer. The second low pass filter has a controllable cutoff frequency. A demodulator recovers an information signal represented by the received RF signal from output signals of the first and second low pass filters. A frequency error detector operates for detecting an error between a frequency of a carrier of the received RF signal and the frequency of the first local oscillator signal in response to the information signal recovered by the demodulator. An oscillator controller operates for controlling the frequency of the first local oscillator signal in response to the error detected by the frequency error detector. A filter controller operates for controlling the cutoff frequencies of the first and second low pass filters in response to the error detected by the frequency error detector.
