Patent number: 6098435Abstract: A bending order which provides a highest possible bending accuracy is determined. First a bending order generating section generates a plurality of bending orders possible for bending operation. Then, whether the bend angle of each bend can be measured in each generated bending order is checked by a measurement judging section. For each bend which has been determined as an objective bend "impossible to measure", a reference bend whose correction value for a die driving amount is to be used for calculating a correction value for the objective bend is set by a correction condition setting section. Weighting is carried out by a weight setting section based on the degree of the correlation between the processing factors of the objective bend and the processing factors of its associated reference bend, and the weights assigned to all the objective bends are summed by a weight sum computing section.Type: GrantFiled: June 2, 1998Date of Patent: August 8, 2000Assignees: Komatsu Ltd., Komatsu Industries CorporationInventor: Masaaki Takada

Patent number: 6087869Abstract: A digital PLL circuit recovers a clock signal from an analog baseband signal. The PLL circuit has a phase comparator. The phase comparator provides a loop filter with a control value for a period of the recovered clock signal after a determination is made. If the determination is that the baseband signal has crossed a transition level, the control value corresponds to a time difference between a sampling point and a transition-level crossing point of the baseband signal. If the determination is that the baseband signal has not crossed the transition level, the control value is 0. The PLL circuit shortens a lockup time and provides stable operation even if the baseband signal involves an offset.Type: GrantFiled: October 6, 1998Date of Patent: July 11, 2000Assignee: Fujitsu LimitedInventors: Syouji Ohishi, Masaya Tamamura, Koichi Hatta

Patent number: 6079232Abstract: A widened loop is formed by using a flat knitting machine which has at least a pair of needle beds and one of the needle beds can be moved sideways. A widening needle is made to be empty, and yarn is fed from one end of the knitting range to a needle short of the widening needle. Next, yarn is not fed to the widening needle but to a needle next to the widening needle. The yarn feeder is reversed and yarn is fed to the widening needle. Then the yarn feeder is reversed again and yarn is fed to a needle next to the needle to which yarn has been fed. According to the method loops 21, 23 on both sides of the widened loop 11 are connected together by a cross-over yarn 25, and the widened loop 11 is held by a loop 13 of the previous course. Therefore it will not be pulled up. Because of these arrangements, an open gap will be hardly generated around the widened loop 11.Type: GrantFiled: March 2, 1999Date of Patent: June 27, 2000Assignee: Shima Seiki Manufacturing, Ltd.Inventor: Manabu Yui
