Patent number: 5603714Abstract: For the purpose of facilitating correction of front-to-back and lateral vertebra curvature in scoliosis and the like, vertebra screws are passed through vertebra plates with spikes that dig into the sides of vertebrae and are screwed into each vertebra. The vertebra screws have rod passage holes in their heads, respectively, which holes are partially open on the side. A screw hole is provided at the top surface of each head. Rods are inserted into and passed through all the rod passage holes via the side openings in the heads of all the vertebra screws, the set-screws being each screwed into screw hole formed in the top surface of the head of the vertebra screw for the purpose of fixing the rods to the vertebra screws.Type: GrantFiled: December 12, 1994Date of Patent: February 18, 1997Assignee: Mizuho Ika Kogyo Kabushiki KaishaInventors: Kiyoshi Kaneda, Shoichi Takahashi, Yoshiharu Asai, Takao Shimizu

Patent number: 4852673Abstract: A region where a load cell and a weighing hopper or a scale plate are coupled to each other is surrounded by a radio wave inhibiting member. When a weighing apparatus is used in a place subjected to extraneous radio waves of a high electric field intensity, and a high-frequency voltage is induced in the weighing hopper or the scale plate which serves as an antenna, the radio wave inhibiting member prevents a high-frequency current produced by the high-frequency voltage from flowing into the load cell. Therefore, the weighing apparatus is completely protected against any weighing errors which would otherwise result from radio interference with the load cell.Type: GrantFiled: July 29, 1988Date of Patent: August 1, 1989Assignee: Ishida Scales Mfg. Co., Ltd.Inventors: Yoshiharu Asai, Shinji Tsukamoto, Shuji Murata

Patent number: 4645019Abstract: A weighing method comprising a process in which a plurality of weighing machines weigh goods, and the weighing values obtained by the weighing machines are combinational-added to compute total weight of all the combinations, so that a combination equal to or nearest the set weight is obtained among the combinations of total weight, thereby discharging groups of goods corresponding to the obtained combination from the weighing machines corresponding thereto. Hence, the weighing method can carry out the weighing of an extremely high accuracy even when the objective goods are larger in the weight and dispersion thereof or relatively smaller in the set weight in comparison with the unit weight. Also, it is possible for the method to divide weighing values gained from each weighing machine by the unit weight of the goods and convert the values into the number of goods and then the same combinational addition is carried out, thereby accurately measuring a desired number of goods.Type: GrantFiled: October 4, 1985Date of Patent: February 24, 1987Assignee: Kabushiki Kaisha Ishida Koki SeisakushoInventors: Kazukiyo Minamida, Yoshiharu Asai

Patent number: 4533006Abstract: A plurality of weighing data are combined to find a total weight combination closest to a preset value within an allowable preset range. Articles are discharged from those weighing machines which give such a total weight combination. For such a combinatorial computation, the empty weighing machines are first detected from among the weighing machines for which the combinatorial computation has been carried out, and then articles are supplied to the empty weighing machines. Weighing data from a number of weighing machines, selected from a plurality of weighing machines, are combined to allow selection of a weight combination equal or closest to the preset value. If a total weight combination given by the selected weighing machines falls within the allowable preset range, then articles are discharged from those weighing machines which give such a total weight combination during a first cycle.Type: GrantFiled: April 29, 1983Date of Patent: August 6, 1985Assignee: Kabushiki Kaisha Ishida Koki SeisakushoInventors: Kazukiyo Minamida, Yoshiharu Asai

Patent number: 4396078Abstract: Improvements in a weighing or counting method wherein on the basis of weight data on a plurality of groups of articles obtained from a plurality of weighing machines, the respective additive values of all possible or desired number of combinations are found, the additive value of a particular combination which is equal or the nearest to a set value is retrieved, and the weighing machines corresponding to the combination selected are actuated to discharge articles contained therein. During the discharge of articles from the weighing machines corresponding to the selected combination and during the subsequent feeding of fresh articles into the same weighing machines, similar combinatorial operation is effected on the basis of weight data from a fixed number of weighing machines which were not selected, or did not discharge their articles, and a particular combination whose additive value is equal or the nearest to the set value is determined as the combination for the next discharge.Type: GrantFiled: November 12, 1981Date of Patent: August 2, 1983Assignee: Kabushiki Kaisha Ishida Koki SeisakushoInventors: Kazukiyo Minamida, Yoshiharu Asai
