摘要： A microcomputer provided in a camera body uses a data signal read by sensors facing the data disk of a film cartridge as a positional signal to set the stop position of the spool for providing exposed/unexposed indication to the film. The voltage of the power supply of the camera is detected to modulate a pulse duration by which the number of rotations of the motor can be kept constant in rewinding the film. The sensors are disposed upstream in the rotational direction of the data disk by a certain angle .theta. with respect to the point at which the spool is stopped in order to prevent the dislocation between the display mark of the cartridge and the pointing mark of the data disk. The microcomputer discriminates whether or not data has been read. The mechanism for feeding the film is controlled to set the film at a predetermined position after the decision that the data has been read.

摘要： A camera has a function of determining whether a frame is exposed or unexposed by reproducing signals recorded on a magnetic-recording region of a film. When a film cartridge is loaded into the camera, the film is fed out therefrom. If it is determined that a noise having a level higher than a reference level is included in a reproduced signal read by a magnetic head, for reading the signals recorded on the magnetic-recording region, before the magnetic head reaches the magnetic-recording region, film feeding is stopped and a warning is issued.

摘要： A DC power supply apparatus includes an input-side rectifier which rectifies an input AC voltage and supplies the rectified voltage to a voltage-boosting converter. The voltage-boosting converter converts the supplied voltage to a voltage of a predetermined magnitude. The predetermined magnitude voltage is, then, converted to a high-frequency voltage by an inverter and applied to a primary winding of a transformer. An output-side rectifier rectifies a high-frequency voltage induced in a secondary winding of the transformer. The inverter includes IGBTs and diodes, which are connected in a full-bridge configuration. A capacitor is connected in parallel with each IGBT. When the IGBTs are rendered conductive by the charging and discharging of the capacitors, no current flows through the IGBTs, and when the IGBTs are rendered nonconductive, the voltages applied to the IGBTs are made to become zero.

摘要： The present invention provides an optical amplifier for amplifying and outputting an input optical signal, and the optical amplifier comprises an erbium-doped optical fiber (EDF) (3), a laser diode (1), a WDM coupler (2), and a temperature setting control unit (8). A pumping light outputted from the laser diode (1) is divided at a given wavelength by the WDM coupler (2) to a light component on long wavelength side and a light component on short wavelength side, and these are separately outputted. Among these light components, the light component on long wavelength side is inputted to the EDF (3) as a forward pumping light. The light component on short wavelength side is inputted as a backward pumping light. The temperature setting control unit (8) sets a ratio of forward pumping light intensity to backward pumping light intensity and controls temperature of the laser light source according to the preset value.

摘要： An optical direct amplifier lowers the power consumption with a simple structure at a low cost. This amplifier includes an optical amplification medium (e.g., optical fiber) that carries out an optical amplification function in response to optical excitation by an exciting light source (e.g., semiconductor laser); a temperature controller for controlling the temperature of the amplification medium; a heat radiating member for radiating the heat generated by the light source; and a heat transmission regulator (e.g., Peltier module) for allowing the heat to flow into the amplification medium from the light source and for preventing the heat from flowing into the light source from the amplification medium. The amplification medium is heated by application of the heat generated by the light source by way of the heat radiating member and the heat transmission regulator.

摘要： A wavelength within an amplifying wavelength band of an optical amplifier is introduced into the optical amplifier at all times or when an interruption and/or reduction of a ray of input light is detected. When the interruption and/or reduction of the input light is detected, an output of the excited light is interrupted or reduced, an optical switch is controlled so that the input light is interrupted, and after the input light is restored, a transmittivity of the optical switch is progressively increased or the input light is passed for a constant period of protection time. Thus, when the input light has been restored, a light surge may be reduced without any adverse affect of a reverse distribution of the optical amplifier. In the case where the input light is abruptly raised during a period of moderation of the excited level, it is possible to suppress the light surge caused by the long service life due to the natural discharge of the excited level.

摘要： A camera (100), suitable for using photographic film (18) with a magnetic track (33), includes a transporting mechanism (M, 22) for transporting the film along a film transport path, a magnetic head (11) positioned adjacent the film transport path so as to read information magnetically recorded on an adjacent portion of the magnetic track, signal processing circuits (12, 42) to provide a digital output signal responsive to thus read information, and a microcomputer (13) for comparing a digital output signal to predetermined threshold levels in order to determine whether or not information is recorded on the portion of the magnetic track being read by the magnetic head and for setting the threshold values. The threshold levels can be set in accordance with a level of the digital output signal when magnetically recorded information is not being read by the magnetic head, e.g., before the film is fed or during the feeding of the film before the first frame reaches the magnetic head. The camera can also include a detector (45) for detecting information (27) indicative of the type of film in the camera and the threshold levels can be set in accordance with the type of film detected by the detector. The threshold levels can be upper and lower threshold values centered on a predetermined value.
