摘要： A light-source driver for a light-source, detachable from an endoscope body includes a first switch, a pilot lamp, a warning lamp, a second switch, and a light switcher. The first switch switches between the On-state and Off-state in connection with the attachment and detachment of the light-source to the endoscope body. The pilot lamp indicates that the illumination light source is energized. The warning lamp indicates that the output voltage of a battery has dropped below a predetermined value. The second switch switches the warning lamp between the On-state and Off-state in connection with the On-state and Off-state of the first switch. The light switcher switches the pilot lamp to the Off-state and enables the second switch when the second switch is set to the On-state and the output voltage has declined to or below the predetermined value.

摘要： An ink transfer printer has an electrically-insulated base plate. An array of electric heater elements, aligned with each other, is provided on a surface of the base plate, the heater elements being selectively and electrically energized in accordance with a series of digital image-pixel signals. A frame member, having an opening, is securely provided on the base plate such that the array of elements is encompassed by the opening of the frame member. A sheet of film covers the frame member such that the opening of the frame member is defined as an ink space fillable with ink, and the film sheet has a plurality of fine pores arranged along the array, with at least one of the plurality of fine pores being allocated to each of the heater elements. A heat dissipating conductor is formed of a thermal conductive material, and is associated with the film sheet such that thermal energy, locally generated by an electrical energization of at least one of the electric heater elements, is promptly dissipated.

摘要： In an electronic endoscope system, an imaging device images a subject at a first frame frequency. A signal generating unit receives image signals of the subject imaged by the imaging device to generate signals of a standard TV system having a second frame frequency that is approximately n/m-fold (where, n and m are natural numbers, and n is unequal to m) of the first frame frequency. Then, a timing control unit synchronizes the first frame frequency of the imaging device with the second frame frequency using a predetermined timing signal output by the signal generating unit. The timing controller can also synchronize a first frame frequency of a color field sequential illumination unit with a second frame frequency using a predetermined timing signal.

摘要： In an electronic endoscope apparatus each of the signals of a plurality of systems output from at least one solid state imaging device is judged by a signal monitoring device as to whether it is normal or not. On the basis of the judged result, the processing mode corresponding to each of the signals of the plurality of systems is changed and each signal is processed. If an abnormality occurs, an observed image with which the endoscope inspection can continue will be secured to be safe. Further, in the electronic endoscope apparatus, when the output signal from the solid state imaging device is judged to be abnormal, the amount of illuminating light will be attenuated, the danger by the excessive amount of illuminating light will be avoided and the safety of the person being monitored will be secured.

摘要： A charge detection circuit is capable of converting electrostatic charge quantities on a solid-state imaging chip into voltage signals of negative polarity. The voltage signals of the negative polarity are suppled to a DC-coupled polarity inversion circuit which inverts the polarity of the signals and amplifies the signals. In consequence, the generation of heat in the transistor of the outpout stage is reduced so as to suppress undesirable temperature rise of the solid-state imaging chip.

摘要： An optical disk apparatus comprises an optical pickup having an optical pickup body carrying a laser and a photodetector responsive to light emitted from the laser and reflected by the optical disk for producing tracking error signals mounted on the optical pickup body for reciprocal movement in a tracking direction responsive to operation of an actuator, and supports an objective for focusing the beam on the disk. A position sensor produces position signals in response to displacement of the movable portion in the tracking direction. Finally a servo tracking circuit outputs driving signals to the actuator on the basis of tracking error signals produced either in response to tracking error signals produced from outputs of the photodetector and position signals produced from output signals of the position sensor, in response only to the latter. The optical disk apparatus having the foregoing construction eliminates direct-current offset included in tracking error signals, stabilizes driving of the objective, and reduces access time.
