    摘要: A discharge light comprising a light emitting tube (1) encapsulating a discharging medium, an inner electrode (2) disposed in the light emitting tube, and an outer electrode unit (4) fixed to the outside of the light emitting tube. The outer electrode unit comprises a plurality of outer electrodes (4b) arranged intermittently in the axial direction of the tube and having a part abutting on the outer wall face of the light emitting tube, and a part (4c) engaging with the light emitting tube while coupling the outer electrodes thereof integrally, wherein the engaging part clamps the light emitting tube at a part thereof thus holding the outer electrode unit around the light emitting tube. The light emitting tube is lighted by applying a voltage between the inner electrode and the outer electrode. The outer electrode can be fixed readily to the light emitting tube and the plurality of outer electrodes can be held against the light emitting tube with high accuracy.

    摘要: By more widely diffusing light from a rod light source, particularly in the direction of the length of the rod light source than conventional strobe lights and image recorders, a strobe light of the present invention and an image recorder containing the strobe light provide luminous intensity distribution characteristics including a light emitting angle large enough to cover, for example, landscape images and the angle of coverage of imaging lenses with a short focal length. This allows the light emitting angle in the direction of the length of the rod light source to increase during wide-angle imaging, with little variation in the luminous intensity distribution characteristics in the direction at right angles to the direction of the length of the rod light source, as compared with known-arrangement strobe lights.

    摘要: There are video and sound recording devices such as movie cameras or video cameras with an automatic focusing system of the type for setting a photographic lens to a position at which an object can be sharply focused in response to the signal which is representative of a distance from the camera to the object and obtained by measuring the time interval from the time when the ultrasonic waves are transmitted at a predetermined repetition frequency to the object to the time when the echo from the object is received. Such devices have a common defect that a microphone picks up impulse-like noise generated from an ultrasonic transducer especially at the start point of ultrasonic waves. To overcome this problem, the present invention provides an audible noise elimination or suppression means or a control circuit which operates in synchronism with the ultrasonic wave transmission so that an audio signal processing system attenuates the audio output signal.
