Abstract: Provided are an analog-to-digital (AD) converter, a sensor processing circuit, and a sensor system capable of improving responsiveness of feedback control. AD converter includes input part, AD conversion part, first output part, and second output part. The analog signal output from sensor is input to input part. AD conversion part digitally converts an analog signal to generate first digital data and second digital data. First output part outputs the first digital data to control circuit. Second output part outputs the second digital data to sensor before first output part outputs the first digital data.

Abstract: A small bowel endoscopic system of an ileus tube type using a monolithic composite optical fiber that can be applied with an ileus tube employed to administer a contrast agent or the like to a patient suffering from ileus and which is an integral assembly of a large-diameter optical fiber with a core/cladding structure intended for laser light transmission and a multi-core image fiber section surrounding that optical fiber to enable image transmission.

Abstract: This invention provides a self-running cleaning apparatus and self-cleaning method that is capable of efficiently moving over the entire bottom surface of a pool and cleaning the entire bottom surface of the pool in a short period of time. A movement-control unit 50 operates a right motor 51, left motor 53 and displacement motor 55 based on a movement-operation program that is stored in the operation memory 57, and moves the self-running cleaning apparatus according to information received from distance sensors 16 to 21 that are located on the front, right side and left side. The operation memory 57 stores the wall-movement operation, detour-movement operation, 90-degree right turn operation, 180-degree right turn operation, 180-degree left turn operation and position-detection operation as the movement-operation program.
