    摘要： Interference measuring apparatus having an optical system for dividing a coherent light beam into two light beams, and causing the divided two light beams to pass along discrete optical paths. The light beams are made into linearly polarized light beams orthogonal to each other and given modulation to the phase of the wave front of at least one of them. The wave fronts of the linearly polarized light beams are superposed one upon the others. A light dividing member divides the light beams superposed one upon the other by the optical system into a plurality of light beams. A polarizing plate takes out each light beam with a 45° polarized component, and a plurality of light receiving elements individually receive the light beams taken out by the polarizing plate.

    摘要： An image processing apparatus for reading an image pattern such as characters, graphics or the like written on a printed matter comprises: a lamp for illuminating such an image pattern; a photo-sensor as an image reading unit for converting the light reflected from the pattern to an electrical signal as multi-value digital data; a converter for converting the output data from the photo-sensor to a binary digital value on the basis of the maximum value and the minimum value of this data; and a control unit for controlling the photo-sensor so as to stabilize the binary output data from the converter on the basis of this output data. With this apparatus, the image pattern is converted to the mechanical vibrational pattern or enlarged display pattern due to the piezoelectric elements or LEDs, thereby enabling a blind person or person with poor vision to easily and certainly perceive the characters or graphic information on the printed matter.

    摘要： A power saving type indicator apparatus for a telephone line. Existence of one of input signals on a telephone line is indicated by actuating an indicator and existence of the other is indicated by deactuating the indicator so that the consumption of electric power in indicating the presence and absence of the input signals is reduced substantially. Furthermore, in connection with another indicator apparatus which indicates the presence of the other input signal by actuating the indicator, indication of signals is so controlled as not to indicate the same signal by actuating two indicators at the same time. Thereby, a further saving of electric power in indicating such signals will be attained. By saving the electric power consumed in signal indication in this manner, a substantial extention of useful life of such a communications system is attained.

    摘要： An optical type encoder includes a light-emitting element, a scale, a light receiving element for detecting light from the scale when a light beam from the light-emitting element is projected onto the scale, an incremental signal resulting from displacement of the scale being obtained by detection by the light receiving element, two or more mark portions for producing an origin signal formed on the scale, and an origin detecting system for detecting the mark portions for producing the origin signal. The rising position or the falling position of at least one pulse signal indicative of the origin is determined by the detection signals of the two or more mark portions for producing the origin signal by the origin detecting system.
