Title: Image reader, image reading method and image forming apparatus
Inventor: FUTAMI HIROYUKI
IPC: H04N5/335
Filed: 2002-01-31
Abstract: <P>PROBLEM TO BE SOLVED: To acquire exact image information by sampling the output electric signal of a solid-state imaging device within a signal period.  <P>SOLUTION: A time point to sample the output of the solid-state imaging device (Figure 6 (A)) in a sampling circuit is made variable (sampling positions (a)-(d)) and the output of the sampling circuit is made into fixed output by automatic gain control in an amplifier circuit. Thereby, when the sampling position is changed, by detecting the sampling position of a time point (sampling position (c)) in which an amplified gain value becomes minimum from the change of the amplified gain value in the amplifier circuit (Figure 6 (B)), the sampling position within the signal period of an output waveform from the solid-state imaging device can be extracted.  <P>COPYRIGHT: (C)2003,JPO

Title: Method and device for fluorescent image detection and method and device for dna inspection
Inventor: OSHIDA YOSHITADA
IPC: C12M1/00
Filed: 2002-02-13
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that it is difficult to widen the dynamic range for fluorescence detection without sacrificing detecting time by maintaining detection sensitivity in a sufficiently high state although it is needed to increase the dynamic range to about 10,000 or higher at the time of performing DNA expression, analysis, etc., because the ordinary dynamic range for fluorescence detection is <1,000.  <P>SOLUTION: While weak exciting light and strong exciting light are alternately projected in one pixel, fluorescence of both intensities is detected and the intensities of the fluorescence are detected from these two data. In addition, at the time of detecting a fluorescent image obtained from the exciting light of one intensity by branching the image, the intensities of the fluorescence are detected by multiplying the intensity ratio between detected light rays by ten to several hundreds times and the intensities of the fluorescence are detected from the data of both intensities. Thus fluorescence detection is performed over a wide dynamic range. In addition, the fluorescence detection is made possible in a three-digit or >4-digit dynamic range by making the detecting time longer by performing photon counting and detection and multi-spot detection.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-02-21
Abstract: PROBLEM TO BE SOLVED: To provide a transmitting circuit apparatus with excellent linearity and low power consumption that is applied to digital radio communication adopting a modulation system such as the QPSK. SOLUTION: A frequency modulator 1 performs frequency modulation of a carrier wave signal with a frequency modulation component of vector modulation. A high-order sigma delta modulator 3 performs signal delta modulation of the amplitude modulation component of the vector modulation. An amplitude modulator 2 performs sigma delta modulation of an output signal from the frequency modulator 1 with the sigma delta modulated amplitude component. A band pass filter reduces an unnecessary frequency component of an output from the amplitude modulator 2 and provides an output of the result. Since the amplitude modulator is used in a state close to saturation and includes less components depending on the analog characteristic, the amplitude modulator is highly efficient so as to attain low current consumption and can easily ensure the linearity.
