Inventor: SHIRAKAWA YOSHIHIRO
IPC: H01M10/05
Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To efficiently manufacture a sack-shaped envelope for a secondary battery with high quality.  <P>SOLUTION: The sack-shaped envelope having an opening is formed by pressing the edges of crossing two sides of a sheet member 1 folded in half from outside. Seal blocks 93, 93 have L-shaped end surface 93b for pressing corresponding to the edges of crossing two sides. The crimping mechanism is constructed so as to push in the seal blocks 93, 93 along the line vertical to a surface of the sheet member 1 to be pressed through a center of gravity by a cylinder 11 (pressing part). As the cylinder 11 (pressing part) uniformly pushes in the seal blocks 93, 93 having L-shaped end surface 93b, the secondary battery with high quality can be efficiently manufactured without forming any knots.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for controlling an actuator for reducing load on a controller by simply performing a vibration suppression and a suspension device using the same method.  <P>SOLUTION: An electromagnetic suspension unit 2 has a linear motor 8 and a rotating motor 9 for rotating an outer cylinder of the linear motor 8. Vibration acting on a vehicle is separated into low frequency signals and high frequency signals by a low-pass filter 85. The rotating motor 9 is controlled by the low frequency signals and the linear motor 8 is controlled by the high frequency signals. A movable spring receiver is displaced in the longitudinal direction of the outer cylinder of the linear motor 8 by an operation of the rotating motor 9, spring force of a coil spring is changed and a vehicle height adjustment is performed. By using two driving circuits (a linear motor driver 56 and a rotating motor driver 61, for instance) for the one electromagnetic suspension unit 2, the vibration suppression and vehicle height adjustment are performed in excellent states, the driving circuits can be reduced, and load of the controller can be reduced.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Filed: 2003-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To prevent illegal copy utilizing analog image data obtained by decoding of encoded data since the image data are remarkably deteriorated in encoding and decoding in the second time and afterward.  <P>SOLUTION: A high-pass coefficient removal part 145 in an encoding part 135 removes coefficient data (conversion coefficients) of a high-pass frequency region regarding prescribed blocks (for example, every other blocks in at least one of horizontal and vertical directions) among pieces of coefficient data DT1 of each block quantized by a quantization circuit 144. In a decoding part, regarding the blocks from which the coefficient data of the high-pass frequency region are removed, interpolation is performed by using the coefficient data of a block located in the vicinity of the block. In the encoding, decoding in the second time and afterward, the coefficient data itself to be interpolated in the case of decoding are already deteriorated since a block position is shifted to a block position in encoding, decoding in the first time because of fluctuation of a sampling phase.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
