Publication number: 20090252190Abstract: In a method of fabricating a semiconductor optical device, a semiconductor region is formed by growing an InP lower film, a active region, an InP upper film and a capping film on a substrate sequentially. Material of the capping film is different from that of InP. Next, a mask is formed on the capping film, and the semiconductor region is etched using the mask to form a semiconductor stripe mesa, which includes an InP lower cladding layer, a active layer, an InP upper cladding layer and a capping layer. The active layer comprises aluminum-based III-V compound. A width of the top surface of the capping layer is greater than that of a width of the bottom surface of the capping layer. A width of the top surface of the InP upper cladding layer is smaller than that of the bottom surface of the InP upper cladding layer.

Patent number: 7436144Abstract: A CPU calculates, based on a frequency command value for driving a motor and on a state quantity of the motor, an output-voltage command value in which only the phase advances while amplitude is constant in each calculation period, without reducing the calculation period. An ASIC reflects the output-voltage command value in a triangular wave signal in a time-series order to compare with each other, and outputs a PWM signal to a switching circuit. Thus, a waveform of an output voltage is made close to a sine wave irrespective of an output frequency being high or low, and a processing load of the CPU is reduced.Type: GrantFiled: September 30, 2003Date of Patent: October 14, 2008Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Manabu Yoshimura, Toshiyuki Kaitani

Patent number: 7366565Abstract: In an exercise machine, when a measurement starts, an electrocardiographic signal is detected by an electrocardiographic sensor 1 (ST33), a load drive is started (ST4), and heartbeat rate intervals of the electrocardiographic signal are sequentially obtained. A fluctuation of heartbeat rate intervals PI(n) % is obtained from a calculation formula in which the RR interval RR(n+1) of the current heartbeat is subtracted from the RR interval RR(n) of the previous heartbeat, which is then divided by RR(n) and multiplied by 100% (ST5). Entropy is calculated from 128 pieces of such PI (ST6). From the change of the entropy under the gradually increasing load (ST8), a minimum point of the entropy is obtained, which point is designated as an anaerobic threshold point (ST7). The load of the exercise machine is controlled employing this anaerobic threshold.Type: GrantFiled: December 5, 2002Date of Patent: April 29, 2008Assignee: Omron Healthcare Co., Ltd.Inventors: Toshikazu Shiga, Tatsuya Kobayashi, Hiromi Matsumoto, Manabu Yoshimura

Patent number: 6912391Abstract: 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.Type: GrantFiled: August 10, 2001Date of Patent: June 28, 2005Assignees: Hitachi, Ltd., KDDI CorporationInventors: Satoshi Masuda, Shirou Mazawa, Manabu Yoshimura, Masato Inagaki, Yoshio Takauchi, Akira Yamaguchi
