    摘要: A digital signal is provided by correcting image signal distortions contained in an image signal outputted from an elongated direct contact type image sensor in an image reader such as a facsimile device, which image sensor reads patterns on a document in contact with the document. The image signal distortions of the sensor output are so-called shading distortions due to sensitivity distribution of sensor elements or distribution of light from light sources onto the document. Signal distortions are corrected from both a white signal outputted from the sensor when a white document is read and a black signal outputted when a black document is read. The white signal and the black signal are stored and reproduced to generate a reference signal which is obtained by dividing the voltage range across both the signals at a predetermined ratio. The digital signal is obtained by comparing the sensor output with the reference signal. If necessary, a pseudo-black signal may be produced by dividing the voltage of the white signal.

    摘要: In a contact-type image sensor for use in a facsimile equipment or the like, the surface of the sensor is provided with a transparent film which is electroconductive and of which the surface that is in contact with the sensor elements is formed as a roughened surface capable of scattering light. By virtue of the provision of this film, static electricity generated during the running of the original is prevented from causing fluctuations in the sensor output voltage. In addition, light reflected by the surface of the transparent film is prevented from becoming directly incident on the sensor elements and, hence, from causing abnormal increases in the sensor output.

    摘要: A contact type image sensor comprises a transparent substrate, photoelectric conversion elements disposed on the substrate, and an opaque film disposed selectively over the first photoelectric conversion elements. The first photoelectric conversion element over which the opaque film is disposed indicates a reference quantity of received light. The second photoelectric conversion element connected with the first photoelectric conversion element in adjacent relationship and having no opaque film disposed thereover indicates a quantity of light from an original document. A signal free from a varying luminance of the light source is obtained from the junction point of the first and second photoelectric conversion elements.

    摘要: In an apparatus for measuring thickness of a thin film, which is formed through a conductor, preventing the measurement from an error due to the curve or bend on a substrate surface or a moving surface of a stage, but without necessity of a large-scaled facility, an electric filed is applied between a probe 10 and a stage 8, so as to obtain an electrostatic capacitance of the substrate 3, an electrostatic capacitance of an insulating film, which is formed between the substrate 3, and an electrostatic capacitance defined starting from the substrate 3 to the thin film 4. The electrostatic capacitance between the substrate 3 and the thin film 4 is measured at plural numbers of places covering over the entire surface of the thin film 4. The probe 10 is so supported that the contact load “P” comes to be constant, by the probe 10 onto the thin film 4. A contact area of the probe 10 between the thin film 4 is calculated out through a predetermined equation, assuming the load “P” is constant. From respective electrostatic capacitances and the contact area measured, a distribution of thickness of the thin film 4 over the entire area thereof.

    摘要: An ultrasound diagnostic apparatus 1 causes discharge means 4 to apply a discharge pulse (having a peak value equal to or greater than a collapse voltage) between electrodes of an ultrasound transducer 20 a plurality of time while inverting the polarity of the discharge pulse each time, to thereby accelerate discharge of the charge accumulated in the diaphragm of the ultrasound transducer 20, so that a transmission-reception sensitivity offset can be caused to quickly approach zero. The charge is discharged instantaneously. That is, it is possible to quickly calibrate a transmission-reception sensitivity drift stemming from time-course accumulation of charge flowing into the diaphragm between the electrodes upon application of a DC bias thereto.

    摘要: The receive sensitivity of an ultrasound array transducer structured with a diaphragm electro-acoustic transducer (101) being a basic unit is affected by change in a charge amount with elapsed time due to leakage or the like, which causes drift of the primary beam sensitivity, degradation in the acoustic SN ratio due to a rise in the acoustic noise level, and degradation in the directivity of an ultrasound beam. To addressing this problem, a charge controller (charge monitor 211) is provided to control charge in an electro-acoustic transducer (101). A charge monitoring section (102) monitors the change in the charge amount. When change in the charge amount is small, transmit sensitivity or receive sensitivity is calibrated by a controller (104) by, for example, multiplying a receive signal by a calibration coefficient corresponding to the change amount. Further, when the change in the charge amount is large, for example, charges can be re-emitted from a charge emitter (103).
