IPC: G02B7/28
Filed: 1986-03-25
Abstract: PURPOSE:To project a pattern with specific luminance distribution to an object with a simple constitution by forming the projection pattern by plural light emitting element, applying current gradient to each light emitting element group to supply current and projecting the object with unsufficient light emission. CONSTITUTION:The projection pattern 108 formed by LED chips 201-203 in a LED element group having a metallic film electrode 201b or the like on its center and making the center part dark and the periphery bright is inclined by a prescribed angle from the optical axis of a projection lens 107. When the pattern 108 is projected to an object with less light emission, a projection pattern based on the chips 201-203 is projected to the object in accordance with the distance of the object. The projection light formed on the object is detected by a photoelectric transducer array 106 of a camera 105. In this case, current gradient is applied to the current to the supplied to the chips 201-203, so that sufficient light is supplied to the object arranged on a far distance and highly accurate automatic focus detection can be attained by projecting a pattern with a specific luminance distribution appropriate for the distance of the object.

Title: Detecting circuit of hit of electric power source

Filed: 1979-05-31
Abstract: PURPOSE: To obtain an alarm output against hit of electric power source, by providing a compartor in a power source hit detecting circuit of digital system, and providing this comparator with power source voltages obtained by dividing the power source voltage by mutually different dividing ratios.  
     CONSTITUTION: An electric power source voltage Vcc is divided by resistances 1, 2 and supplied to positive phase input 9a of a comparator 9, and Vcc is divided by resistances 3, 4 by a different dividing ratio and supplied to opposite phase input 9b of the comparator 9. The power source of the comparator 9 is supplied through a diode 8, and a resistance 5 and a capacitor 7 are connected parallel to a power source input terminal 9c of the comparator 9. In normal state, it is so set that the positive phase input 9a may have a higher voltage than the opposite phase input 9b, and the output of the comparator 9 is "H". On the other hand, when the Vcc drops momentarily, the positive phase input 9a lowers in proportion to the Vcc, while the opposite phase input 9b, which is forming an RC circuit, lowers more slowly, so that the input 9a becomes lower than the input 9b. As a result, the output of the comparator 9 becomes "L". When this Vcc fluctuates, since the power source for the comparator 9 is supplied from the capacitor 7, an alarm output is obtained when the output becomes "L".
