Title: Automatic focus detector and camera provided with the detector
Inventor: KOBAYASHI KAZUYA
IPC: G02B7/28
Filed: 2001-03-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the influence of the flicker of a fluorescent lamp or the like, and to accurately detect a focus even under low illuminance without slowing focusing operation. SOLUTION: In the automatic focus detector, an optical image is formed on an imaging device by a photographing lens system and converted into a video signal by the imaging device. The video signal includes a high frequency component changed in accordance with the lens position of the photographing lens system, and the focal position of a photographing lens system is detected based on the high frequency component. While changing an image forming state on the imaging device, the video signal is read out in every field cycle VD and is separated to three video signals sampled by 3 VD cycle being the least common multiple of the flicker cycle (1/100 sec) and the field cycle VD (1/60 sec) of a light source in a video signal separation circuit 10.  The peak position of the high frequency component included in the video signal is detected by a peak position detection circuit 20, and the curve of a contrast value is decided by interpolating arithmetic operation based on the peak position so as to detect a focusing position in an interpolating arithmetic operation circuit 30.

Title: Switched reluctance motor, its control method and apparatus, and program thereof
Inventor: YAMAI HIROYUKI
IPC: H02P25/06
Filed: 2001-03-14
Abstract: PROBLEM TO BE SOLVED: To obtain small torque, without reducing current that is allowed to flow to a switched reluctance motor. SOLUTION: Sections θ0u -θ1u of a position angle θ, where current flows to a U-phase coil, include a position angle θ2u . Before and after a position close to the position angle θ2u , the signs of the derivatives dLu /dθ with respect to the position angle θ of inductance LU of the U-phase coil differ. Therefore, the sign of the total of torque, that is generated at sections θ0u -θ2u is opposite to that of the total of torque that is generated at sections θ2u -θ1u , and the total of the toque of the switched reluctance motor, when being illustrated in U phase is determined by the subtraction of both of them. Therefore, even if the torque is small, the current flowing through the U-phase coil is increased for improving noise resistance, thus accurately estimating the position angle θ.

Title: Device for predicting execution result of instruction
Inventor: TAKAMURA AKIHIRO
IPC: G06F9/38
Filed: 2001-03-21
Abstract: PROBLEM TO BE SOLVED: To provide a means to perform branching/value prediction by which high correct answer rate of prediction is realized.
