Title: Thin leaf conveying device and utilizing device therefor
Inventor: TATETSUKI SABURO
IPC: B65H5/02
Filed: 1997-11-12
Abstract: PROBLEM TO BE SOLVED: To provide a thin leaf conveying device to improve the conveyance force of an opposite belt conveying mechanism to convey thin leaves such as bank notes, slips and cards and to provide a utilizing device, for example, a pachinko machine island device. SOLUTION: The conveyance passage 200 of a thin leaf conveying device 300 conveys 100 in a given direction T nipping a thin leaf 100 between the flat belts 45A and 45B (45A1 and 45B1 on the feed side), arranged facing each other, of an opposite belt conveying mechanism 42. A roller 201 (a single or a plural number) for guide arranged in the intermediate of the flat belts 45A and 45B (45A1 and 45B1 on the feed side) is deviated in directions U and V, crossing the given direction T, to bend the conveyance passage 200. Through bending of the conveyance passage 200, a nipping force on the thin leaf 100 between the flat belts 45A and 45B (the 45A1 and 45B1 on the feed side) is increased, whereby a conveyance force is improved.  The positions of pulleys 43B and 44B are displaced from pulleys 43A and 44A and deviated from each other in directions U and V and even in this case, conveyance is effected in a similar manner described above. Jamming is prevented from occurring due to hook of the upper and lower parts 100C of the thin leaf 100 at a guide piece 255 to cover the shafts 201A and 201B of the roller 201.

Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a core reactor with gaps, which prevents the generation of the unequal distribution of the magnetic flux density of yoke cores under operation and enable a reduction in the noise and the loss. SOLUTION: This reactor has a structure, wherein a plurality of pieces of block cores 1a, which are formed by laminating radially blanks consisting of a silicon steel plate and have a section formed into a circular form, are stacked via magnetic gaps 2 to constitute a core leg 1 with gaps, a winding 3 is wound on the periphery of this leg 1 and this leg 1 with a circular section and yoke cores 4 and 5 with a rectangular section are combined integrally with each other.  At this time, as the cores 1a, which oppose to the upper and lower yoke cores 4, respectively spread to the sides of the cores 4 and are constituted into a sectional form of an circular form or a polygonal form, the movement of a magnetic flux from the center part in the laminated direction of the cores 4 to both end parts of the cores 4 and the movement of a magnetic flux in the width direction of the yoke blanks are inhibited. As a result, the blanks in each section part of the cores 4 are equally extended and the generation of an unreasonable compression stress due to a difference between the thermal expansions of the core 4 is prevented. Accordingly, the generation of magnetostrictive noise due to the unreasonable compressive stress is inhibited and a reduction in the noise of the reactor and a reduction in the loss of the reactor become possible.

Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To suppress production of camera-shake caused when an image of a moving object is picked up. SOLUTION: An initial value T0 of a period of a 4-phase drive signal driving a CCD of an image pickup device 1 is calculated according to equation T0 =(L×p)/(f×v), where L is a distance from the CCD to a product 11 (object), (f) is a focal distance of an optical system used between the CCD and the product 11, (v) denotes a mobile speed of the product and (p) denotes an arrangement interval of photo diodes of the CCD. The period T of the drive signal is properly adjusted depending on an image pickup position of the product 11. Since a charge corresponding to an image of a same part of the product is stored in a same potential well formed by the drive signal by generating the drive signal in this way, an image of the product 11 is picked up while camera-shake is suppressed corresponding to the speed of the product 11.
