Abstract: A calibration system that calibrates robots installed in a process includes: a reference measuring element; a flange measuring element attached to a flange provided at an arm tip of each robot; a fixed measuring device configured to measure the flange measuring element of each robot and the reference measuring element; and a controller configured to control the robots, calculate a position and attitude relation between the flange measuring element of each robot and the reference measuring element based on a measured result measured by the fixed measuring device, and calculate an error between a design installation position and attitude of each robot and an actual installation position and attitude of the robot by using the measured position and attitude relation and position and attitude data of the flange measuring element in a robot coordinate system at the time when the robot has been measured by the fixed measuring device.

Abstract: A light detecting module that detects interference light that has exited an exit end surface of an optical fiber in an OCT instrument includes: a ball lens including an incident surface entered by the interference light that has exited the exit end surface, and an exit surface exited by the interference light that has entered the incident surface; and a photodiode including a detecting surface entered by the interference light that has exited the exit surface. The interference light obliquely enters the incident surface with respect to a perpendicular line at an incident position of the interference light. The interference light obliquely exits the exit surface with respect to a perpendicular line at an exit position of the interference light. The interference light obliquely enters the detecting surface with respect to a perpendicular line at an incident position of the interference light.

Abstract: A radio communication terminal, being used in a radio communication systems in which the transmission rate varies depending on radio wave conditions and communication statuses of other users, comprises a reception module which receives packets transmitted by a base station in an idle state of the radio communication terminal, a signal processing module which estimates a transmission rate available in communication based on the packets received by the reception module, and a display module which displays information indicating the transmission rate estimated by the signal processing module.

Abstract: In a mobile communication system, a base station controller has a handoff information management table for storing distance information for each mobile station notified from each of base stations and a detection unit for updating the handoff information management table each time a new handoff information was received from the base stations and detecting any of the mobile stations that is moving out of a service area into an out-of-communication range. The detection unit performs the out-of-range detection by selecting any of the mobile stations currently communicative only with one or more of the border cell base stations as a detection target and comparing the distance information in the handoff information management table with a predetermined threshold value.

Abstract: By obtaining a two-wavelength optical device which can cancel the optical-path difference due to the difference of the wavelengths occurred when two wavelength elements are integrated in one unit, the deterioration of a reproduction signal of an optical disk which may be produced by the optical-path difference is suppressed. In a two-wavelength optical device (1) for reading from and writing to an optical disk and including a plurality of light emitting elements (3), (5) for emitting laser lights (17) having different wavelengths to the optical disk, and a light receiving element (13) for receiving a return light from the optical disk, the respective light emitting elements (3), (5) are arranged at relative positions where the optical-path difference appears due to the difference between the different wavelengths, is cancelled.

Abstract: A method of controlling hand over that reliably performs SHO even when there exists discrepancy between a range of a cell or sector and a range in which communication is possible. A reference value, which is compared with a received level of a perch channel signal for judging timing of starting and ending SHO, is corrected by using a correction value prepared for each combination of an SHO source cell and an SHO destination cell. The reference value is corrected such that SHO is started when the mobile station 10 arrives at a range in which the mobile station 10 can communicate with a base station 21 that covers the SHO destination candidate cell, and the hand over is ended when the mobile station 10 comes out of a range in which the mobile station 10 can communicate with a base station that covers the SHO source cell.
