An automatic film winding device for camera comprising the film winding member of which the outer peripheral portion at one end is formed larger in diameter than the other outer peripheral portion. The automatic film winding device for camera comprises a pressing means mounted on a camera body for pressing the narrowed leading end of the film against the outer peripheral surface of the film winding member at the position where the leading end of the film is received into the film winding chamber. The pressing means is so set that its pressing position corresponds to a part of the cut edge of the narrowed leading end portion of the film, and mounted on the inner surface of a back cover and urged by spring means so as to be capable of pressing the leading end of the film to the film winding member in the winding operation.

A camera with built-in motor having a motor disposed horizontally at the central bottom portion of the camera body and out of path of the input light for driving various drive mechanisms necessary for the photographing. Said motor has two output shafts extending out of the housing of the motor, so that two or more loads may be simultaneously driven by the motor. Said mechanisms are suitably sorted into groups by the magnitudes of the loads imparted by these mechanisms, and these groups are driven by the motor in such a sequence as to maintain a substantially constant level of load on the motor in relation to time.

Provided is a light adjusting noise reduction circuit in which the vibration noise accompanying turning ON/OFF of a piezoelectric transformer. A full bridge circuit is controlled by a full bridge drive circuit so as to switch an input voltage (VB1) from an input voltage source and outputs it to a low pass filter. The output from the low pass filter is supplied to a piezoelectric transformer. The output current (IO) from the piezoelectric transformer is supplied to a discharge tube. Each of FET of the full bridge circuit has a drive frequency decided by a voltage control type oscillator. The full bridge circuit is connected to a duty variable circuit and a peak value control circuit. The peak value control circuit forms a rise and a fall of a waveform to be (1−cosωt).

A track width regulating section having a track width, which is smaller than the resolution obtained by the wavelength of the light used for exposure and development of a resist, is formed between a lower core layer and an upper core layer. Since the width of the upper core layer is larger than the track width, magnetic saturation can be effectively reduced. Inclined faces are formed on the upper surface of the lower core layer so as to be inclined in directions away from the track width regulating section, thereby adequately preventing write fringing.

An electromagnetic wave amplifier and an electromagnetic wave generator operate using electron beams in a vacuum environment. The amplifier, arranged in a vacuum environment, comprises an electron emitting section for emitting electron beams and an amplifying section for amplifying an inputted electromagnetic wave in one direction by utilizing energy received from an electron beam emitted from the electron emitting section and traveling in the vacuum along a dielectric waveguide having a wave-shaped form. The generator, also arranged in a vacuum environment, comprises an electron emitting section for emitting electron beams and an oscillating section for generating an electromagnetic wave by utilizing electron beams emitted from the electron emitting section and travelling in the vacuum along a dielectric waveguide having a composite wave-shaped form.

A shift register 10 receives serial data and outputs parallel data in synchronism with the timing of the serial data received. A shift register group 20, 21 receives bit outputs of the parallel data from the shift register 10. The number of bits of shift registers 20, 21 in the shift register group is set in a certain condition that corresponds to the bit outputs of the parallel data from the shift register 10. A plurality of coincidence circuits 107, 108 are provided, which detects agreement between a preset data starting pattern and the bit arrangement of the data in the shift register group. A selector 306 selects a set of parallel outputs from the shift register group according to the output signal from the coincidence circuits 107, 108. Thus only the shift register 10, performs high-speed operations at the same timing as the received serial data, and the other circuits operate at slower speeds whose timing is several times longer than that of the serial data received, thereby eliminating complex timing and averting difficulty control logic.
