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： 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： 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： An indoor unit for air conditioners of the invention has a front panel (4) having a suction grille (41) at least at a central portion (4a). Indoor air is sucked in through gaps (42) of the suction grille of the front panel (4), and cooled air is blown out into a room (99) through an air outlet (8) located below the front panel (4). A lower portion (4b) of the front panel (4) opposed to a lower portion (3b) of the front grille in proximity to an upper portion of the air outlet (8) is shaped to have dips and bumps. As a result, dew condensations on the front face side of the front panel lower portion can be prevented without causing any cost increase.
