Patent number: 6954264Abstract: In order to improve a measuring precision in case of measuring properties of the optical fiber to be measured, in accordance with returned lights which have wavelengths different from each other, detection is carried out with respect to the returned lights of the wavelengths different from each other, at a timing based on difference of propagation rates between the returned lights in the optical fiber to be measured, and error between the returning points is compensated with respect to each returned light, in the optical pulse testing device for inputting the optical pulse to the optical fiber to be measured, to detect returned lights which have wavelengths different from each other and which are returned back from passing points in the optical fiber to be measured, respectively, in order to measure the properties of the optical fiber to be measured, in accordance with detection results of the returned lights.Type: GrantFiled: June 22, 2004Date of Patent: October 11, 2005Assignee: Yokogawa Electric CorporationInventors: Tetsuya Araki, Makoto Kuratsu, Katsumi Hirata

Patent number: 6839130Abstract: An optical pulse ?0 from a light source section 10 is incident upon an optical fiber 1 through an optical demultiplexer section 20, and its return light is supplied to an optical/electrical processing section 30 as the light of a plurality of different wavelengths ?1 to ?n by the optical demultiplexer section 20, and is respectively converted into electrical signals. Signals of the converted return light are respectively sampled and are averaged by respective processing circuits 402 to 40n of a signal processing section 40 so as to be formed as desired measurement waveforms. In the measurement waveforms, which are the results, data for corresponding sampling points are expressed as measurement data at an identical distance in the optical fiber.Type: GrantFiled: August 2, 2002Date of Patent: January 4, 2005Assignees: Ando Electric Co., Ltd., Kyusyu Ando Electric Co., Ltd.Inventors: Tetsuya Araki, Katsumi Hirata

Patent number: 6009056Abstract: In the operation to access data on a disk, the data reading operation is enabled before the rotary speed of the spindle motor of the disk is completely regulated to thereby minimize the access time and power consumption of the spindle motor for acceleration or deceleration thereof. When the actuator is in the access operation, the motor is compulsorily driven. From a time when the actuator reaches a target track in the access operation to a time when the rotary speed of the motor becomes equal to a predetermined rotary speed, the frequency control signal is created according to the position of the actuator and the rotary speed of the spindle motor. After the data reading operation is commenced, to fixedly set the data transfer rate to a predetermined value, the variable reference clock signal is stepwise corrected to be equal to the fixed master clock signal in a frequency range calculated according to the motor rotating speed and the capture range.Type: GrantFiled: January 22, 1998Date of Patent: December 28, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Tetsuya Araki, Yoshiro Kashiwabara
