Publication number: 20030094933Abstract: A Band gap reference voltage circuit of the present invention includes a first band gap reference voltage formation portion for outputting a first reference voltage and a second band gap reference voltage formation portion for outputting a second reference voltage. The band gap reference voltage circuit then outputs a higher one of the first and second band gap reference voltage formation portions to output a constant reference voltage. Accordingly, even if one of the output voltages decreases caused by applying any stress for the first and second band gap reference voltage formation portions, the higher voltage is output as an output voltage of the band gap reference voltage circuit.Type: ApplicationFiled: October 31, 2002Publication date: May 22, 2003Inventor: Kiyoshi Yamamoto

Publication number: 20030043287Abstract: A three-dimensional image capturing device has a center LED and peripheral LEDs which are arranged around the center LED. The center LED and peripheral LEDs irradiate distance measuring light beams to a measurement subject. The distance measurement light beams are reflected by a surface of the measurement subject, and the reflected light beams are received by an imaging device, so that distances from the imaging device to the measurement subject are sensed in accordance with the received light amount. The irradiation timings of the center LED and the peripheral LEDs are adjusted, in such a manner that, when the measurement subject is a flat plane parallel to the light receiving surface of the imaging device, the reflected light beams from all of the LEDs are simultaneously received by the imaging device.Type: ApplicationFiled: August 30, 2002Publication date: March 6, 2003Applicant: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Shinichi Kakiuchi, Kiyoshi Yamamoto

Patent number: 6034766Abstract: An optical member inspection apparatus is disclosed. A light shielding plate functions to cast a shadow region so that a line sensor receives an image producing a particular defined image data output, generally speaking a dark image representing an absence of light from an illuminator. When an inspection target optical member is inserted in the light path to intersect that shadow region, the line sensor produces the same image data in the event that there is no defect in the optical member. However, a defect in the optical member will enable light from outside that shadow region to be diffused to impinge on the line sensor thereby producing a change in the image data output. Evaluation of the change in the image data output can provide an indication of the degree of defectiveness.Type: GrantFiled: March 5, 1998Date of Patent: March 7, 2000Assignee: Asahi Kogaku Kogyo Kabushiki KaishaInventors: Masayuki Sugiura, Kiyoshi Yamamoto, Taichi Nakanishi
