Title: Method for defining multi-database
Inventor: YAGAWA YUICHI
IPC: G06F12/00
Filed: 2000-06-19
Abstract: PROBLEM TO BE SOLVED: To correctly and easily define the schemer of a multi-database in which plural databases operate cooperatively. SOLUTION: A multi-database defining means registers the element schemer of each database, and uniquely defines the names of a list, and makes the columns correspond to a common data type. Then, the multi-database defining means defines and registers the outside schemer of an application, and defines a map from the outside schemer to the element schemer. Then, the multi- database defining means defines and registers a replica list schemer specifying a range for integrating the outside schemer into a substance, and defines a map from the replica list schemer to the outside schemer.  At the time of outputting an integral schemer to a multi-database server, the multi-database defining means inspects that the element schemer to be referred to by the outside schemer and the outside schemer to be referred to by the replica list schemer correctly exist, and erases the data of the element schemer which is not referred to by the outside schemer in the integral schemer.

Title: Weighing conveyor and weighing device provided with this
Inventor: TAKAHASHI ATSUSHI
IPC: G01G11/00
Filed: 2000-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a weighing conveyor and a weighing device avoiding deterioration of weighing accuracy caused by noise occurring in a weighing signal of a load detector by rotational vibration of a driving motor with a simple structure and without complicating the hardware and software structures. SOLUTION: A conveying face 17 of a conveying mechanism 5 is extended in a horizontal direction L1 so as to horizontally convey a weighing object. A load cell 4 is arranged so as to detect a load by displacement of a straining body 4a in a vertical direction L2. The driving motor 6 is arranged so that a rotary shaft is extended in a vertical direction L3. Since the rotational vibration of the rotary shaft of the driving motor 6 acts in the horizontal direction and it does not displace the straining body 4a, noise of a characteristic frequency does not appear in the weighing signal of the load cell 4 and the deterioration of the weighing accuracy is avoided. Since only the rotary shaft of the driving motor 6 is vertically arranged, the hardware structure is not complicated.  Since the weighing signal of the load cell 4 can be used as it is, the software structure for signal processing is not complicated.
