摘要： An active type distance detecting device wherein either a light emitting element or a light receiving element is operated to scan by a scanning means. A signal for driving the scanning means is interposed between pulse signals for causing the light emitting element to emit flickering light so that the former signal may not overlap with the latter pulse signals in order to reduce fluctuations of a load electric current.

摘要： A distance detector capable of measuring the distance between the range detector and an object by directing a light emitted from a light emission element to the object and receiving the reflected light and advantageously adaptable particularly to small-sized cameras.The light reflected on the object is received by a single light-receiving element. The reflected light is condensed by a condenser and concentrated on the light-receiving element. The light-receiving element comprises an element, for example a photopotentiometric element, varying in the electric output according to the position of the light spot of the reflected light. The output of the element in the form of electric signal continuously varies in proportion to the distance between the range detector and the object.

摘要： A single-lens reflex camera shutter having an operating ring driven in one direction by a gear-rack and pinion combination. The operating ring actuates the diaphragm and shutter blades and is stopped by a stop lever during the taking of an exposure. The stop lever is locked during the taking of an exposure by a signal lever that signals the taking of an exposure and is released upon completion of an exposure to allow the operating ring to continue in its travel and carry out opening of the shutter and opening of the diaphragm blades.

摘要： An electric shutter is opened and closed to effect an exposure in dependence upon the energization of an electromagnet. A switching circuit controls the energization of the electromagnet in accordance with various exposure information, such as diaphragm setting and film sensitivity. An exposure control circuit comprised of a series connection of a diode and a variable resistor is connected in parallel with the electromagnet and adjustably controls the time at which the electromagnet is deenergized to accordingly effect closing of the shutter such that the electromagnet delay time equals the shutter sector advancing time to thereby compensate for fluctuations between the two times.

摘要： The present invention provides a light generation method and a light source that are preferable in obtaining a single-mode light having high outputs, a small wavelength spectral bandwidth, and a low intensity noise. A white output from a white-light source and having wavelength components over a wide-band in a wavelength spectrum passes through an isolator and is then filtered by a disc-shaped optical filter. A transmitted light is input to a semiconductor optical amplifier having its polarization plane regulated by a polarization controller. An output from the amplifier passes through an isolator and is then filtered by a disc-shaped optical filter again to generate a single-mode light having a small spectral bandwidth and high outputs. Polarization control by the polarization controller corresponds to control of the polarization plane of a semiconductor laser in the semiconductor optical amplifier so as to obtain a maximum gain from the amplifier. This configuration enables a single-mode light having a small spectral bandwidth and high outputs to be easily generated at an arbitrary wavelength.

摘要： An auto-focusing device includes a light emitting element for emitting an optical beam to be projected upon an object, an image position detecting element for receiving the optical beam reflected from the object for outputting an image position signal, and range computing circuitry for receiving the image position signal and computing therefrom the range to the object and outputting a corresponding range signal. First and second level deciding circuits decide whether or not the computed data based on the image position signal is at a level validating the computation of the range signal. The level deciding circuits output a remotest or nearer-than-remotest signal dependent upon the computed image position signal if the computed data from the image position signal is not validated. A lens position setting device sets a lens position from either the range signal, the remotest signal or the nearer-than-remotest signal in accordance with the decisions of the first and second level deciding circuits.
