Abstract: Provided is a test apparatus that tests a device under test including an optical coupler transmitting optical signals in a direction perpendicular to a device surface. The test apparatus includes a substrate on which the device under test is to be loaded, an optical transmission path that transmits the optical signals, and a lens section facing the optical coupler on the substrate that focuses the optical signals from an end of either the optical coupler or the optical transmission path to an end of the other.

Abstract: In the disclosed distance measuring device a light source projects a light on an object to be photographed and at least two photo-electric converters each with several light receiving areas receive light reflected by the object. The quantity of electric charge on these areas varies with the quantity of light incident thereon. An electric charge storage stores the electric charges produced at the two converters and a control determines the operation of the light receiving areas of the photo-electric converters according to the electric charge information produced.

Abstract: PROBLEM TO BE SOLVED: To provide an equipment which compensates variation in a picture signal resulting from variation of lighting intensity.
SOLUTION: The equipment compensates variation of light emitted from an light source (1) and propagated along with a lighting path. It is a type of equipment which has a first light sensor which divides spatially and detects the intensity in the first position in the light path and forms en electric image, and has a second light sensor(27, 28, 29, 52, 54) which detects intensity in a second part in the light path, and forms an electric output signal. In this equipment, the second sensor divides spatially and detects the light intensity, and is provided with an evaluation circuit(26) which receives an output signal of the first sensor and also an output signal of the second sensor. The evaluation circuit corrects an input signal emitted from the first sensor, depending on an input signal emitted from the second sensor. The correction is performed so that the output signal of the evaluation circuit may not be substantially dependent on the variation of the light intensity.

Abstract: PROBLEM TO BE SOLVED: To improve processing efficiency by simultaneously deciding whether a processing condition is non-defective or defective by comparing the luminance detected by a luminance sensor with a criterion value. SOLUTION: The laser beam P sent from a laser beam machine body is made incident on a first condenser 9 and is condensed to the processing part A of a work W, by which the work is processed. At this time, a processing beam q is generated and is made into parallel beams by the condenser 9. These parallel beams are made incident on a second condenser 10. The component q1 progressing on a light axis line α is advanced in the as-it-is direction as q10 while being accompanied by some attenuation by a light diffuser 11 between the second condenser 10 and the first luminance sensor 12. The component is made incident only on the first luminance sensor 12. The component q2 except q1 is diffused by the light diffuser 11 and is made into a blurring beam q20 . The beam is made partly incident as the beam of the luminance equal to the first luminance 12 and on the second luminance sensor 13 as well. Decision is made by making comparison with the reference value by using the ratio of q10 and q20 , by which the exact decision is made.

Abstract: PURPOSE: To provide a comfortable indoor visible environment and to enable savings in the electric energy for illumination by separating indoor light into natural and artificial light for detection, and dimming the artificial light according to fluctuations in the natural light. CONSTITUTION: Signals output from a near infrared ray sensor 1, a visible light sensor 2 and a human body sensor 3 are converted from analog to digital form by an A/D converting part 5. A dimming signal tar ambient illumination 10 is output by the first dimming judging portion 6 of a controller 4 in response to time digital signals from the near infrared ray sensor 1 and the visible light sensor 2, and the illumination load of the ambient illumination 10 is controlled by an illumination controlling part 8 according to this output signal. Further, a dimming signal for a task lighting fixture 11 is output by the second dimming judging portion 7 of the controller 4 in response to the digital signals from the visible light sensor 2 and the human body sensor 3, and the illumination load of the task lighting fixture 11 is controlled by an illumination controlling part 9 according to this output signal.
