摘要： A tuner module includes a filter that reduces the signal level outside the frequency band of a selected channel in an input RF signal of terrestrial television broadcasting, a local oscillation circuit that oscillates a local oscillation signal, a mixing circuit that mixes the RF signal in which the signal level outside the frequency band of the selected channel is reduced by the filter and the local oscillation signal oscillated by the local oscillation circuit to downconvert the RF signal to an intermediate frequency signal, and a control circuit that controls the local oscillation frequency of the local oscillation signal oscillated by the local oscillation circuit. The control circuit adjusts the local oscillation frequency to a value that suppresses an effect of a disturbance wave from other channels within a frequency band of the intermediate frequency signal of the selected channel.

摘要： An ink jet printer ejects ink droplets of a plurality of sizes based on image data, and prints dots of a plurality of sizes corresponding to the ink droplets of the plurality of sizes for recording the image. In the ink jet printer, in order to print a smoothing dot close to a normal dot, pulse voltage having a waveform having its printing timing changed from a waveform for printing the normal dot is applied to a piezoelectric element. As a result, an ink jet printer capable of recording high definition images can be provided.

摘要： An ink jet printer is adapted to drive a piezoelectric element by applying pulse voltage having waveforms of A1-A8 based on image data, fly ink drops respectively having sizes corresponding to waveforms A1-A8 of the pulse voltage, and record an image on a recording sheet. In the ink jet printer, a rise rate of pulse voltage having waveforms A1-A3 corresponding to ink drops of relatively small sizes is set such that the rise rate is high compared with that of pulse voltage having waveforms A4-A8.

摘要： A fixing device includes a heater and a fixing belt entrained around first and second supporting rollers. A pressure roller is arranged outside the belt. Also, an elastic forcing member is arranged inside the belt to force a portion of the belt running between the two supporting rollers against the pressure roller so that the belt portion is brought into circumferential contact with the pressure roller to form an extended nipping region. In addition, a braking device connected to an upstream support roller stretches the belt at the nip region. With this arrangement enough amount of heat is supplied to a recording medium and toner image flattening is prevented.

摘要： This invention concerns a fundus camera which can take photographs other than by fluorescence or by fluorescence. An optical device is withdrawn from the optical path of a photographic system at the same time as a barrier filter for taking photographs by fluorescence is inserted and is inserted in the optical path of the photographic system for observation purposes at the same time as the barrier filter is removed. The optical device has the same optical path length as the barrier filter, and thus a focused fundus image attained during observation is not upset when fluorescent photographs are taken.
