摘要： A camera has a data imprinting device having an optical system focussing light from an LED array on a photographic film at first and second positions corresponding to full-size and panorama-size picture formats. In a first embodiment the optical system has two lens elements, at differing distances from the LED array, each aligned to imprint data at one of the two positions. In a second embodiment the optical system has a single lens element which moves from a first lens position to a second lens position at differing distances from the LED array. Amounts of light emitted by the LED array are modulated by a control system to produce correctly exposed imprinted data at both position. The control system compensates for differing numerical apertures of associated with the first and second positions. The control system also compensates for film speed. One embodiment of the invention modulates the amount of emitted light by adjusting a current level driving the LED array. Another embodiment modulates by pulse width modulating the illumination period of the LED array.

摘要： A photoelectric detector device for determining whether or not a body formed with a linear mark lies within a given range comprises an image-forming optical system for forming the image of the linear mark, two slit plates disposed adjacent the focal plane of the optical system and a corresponding number of photoelectric converter means for converting into electrical signals light beams passed through the slits in the plates. The slits each formed in the plates are parallel to the linear mark and correspond in position to the opposite ends of the range. Oscillating means are provided for causing the image-forming light beam passing through the optical system and the plates to be oscillated relative to each other at a predetermined frequency so as to scan the image of the linear mark within a range containing at least the slits. A processing circuit for taking the difference between the output signals from the two photoelectric converters derives from such difference signal a frequency component equal to the oscillation frequency of the oscillating means, thus providing either a positive or a negative signal indicating the position of the linear mark.

摘要： Timers for controlling load circuits, such as motors in motordriven cameras, have ON and OFF intervals which can either be continuously repeated or automatically interrupted after various selected sequences of ON-OFF operations for thereafter holding the load circuit in an energized or de-energized state. The timers comprise a bi-stable circuit having complementary output signals and a pair of CR time-delay circuits for generating timedelayed signals in response to the output signals, the timedelayed signals being coupled to respective inputs of the bistable circuit for causing the bi-stable circuit to be alternately set in first and second states. A load responsive to one of the output signals is energized or de-energized in accordance with the state of the bi-stable circuit. An interrupter circuit responsive to one of the time-delayed signals causes the load to be continuously energized or de-energized after a selected ON-OFF sequence.

摘要： An ellipsometer includes a polarizing optical system, a first and a second optical path changing total reflecting prism, and an analyzer. Light from a light source passes through the polarizing optical system to leave it in the form of elliptical polarized light, which in turn passes through the first total reflection prism in which the elliptical polarized light is given a phase skip difference and deflected so as to impinge on the surface of a sample obliquely with respect thereto. The light so reflected by the first total reflection prism further passes through the second total reflection prism in which the light is given a phase skip difference and deflected in a direction substantially parallel to the optical axis of the polarizing optical system. The light passed through the second total reflection prism is finally extinguished by the analyzer.
