Abstract: There is provided a two-dimensional code capable of performing accurate recognition. The two-dimensional code includes: a code data portion (102) where a plurality of square cells (106) are two-dimensionally arranged to constitute code data; and a plurality of corner cells (104) arranged so as to surround the code data portion (102). The corner cells (104) are configured with a greater area than the square cells (106). When the two-dimensional code is imaged by an imaging device, the corner cells (104) can be recognized in a large scale, thereby improving the two-dimensional code read accuracy.

Abstract: A method for producing a multi layered coating film, by applying a base coating composition as defined in the specification on an article to form a base coating; applying a first clear coating composition as defined in the specification on the base coating to form a first clear coating thereon; subjecting both the base coating and the first clear coating thereon to baking and/or curing to form a cured base coating film and a cured first clear coating film thereon; sanding or polishing at least one part of the cured first clear coating film to form a partially sanded or polished first clear coating film; applying a second clear coating composition as defined in the specification all over the first clear coating film to form a second clear coating; and subjecting the second clear coating to baking and/or curing to form a cured second clear coating film.

Abstract: A data classification processing apparatus assumes that data stored in a database is extracted based on a user instruction. The data classification processing apparatus comprises an information managing unit storing a management point that defines the classification method of the data stored in the database without making the classification method dependent on a particular data item, and an inquiring unit searching the database based on the classification method of the data, which is defined in the management point stored in the information managing unit, in response to a data inquiry from the user.

Abstract: An apparatus for and a computer program for managing a database, which performs a search of data from a database based on predetermined information selected by a user from among information registered as a dictionary, includes a personal dictionary registering unit that registers information on either of or both management and analysis of the data stored in the database to the dictionary as a personal dictionary that is accessible only by a predetermined user, and a dictionary reference unit that outputs the information registered in the dictionary including the information registered as the personal dictionary, and accepts a selection of the predetermined information by the user from among the information output.

Abstract: Retrieving is conducted by employing table disclosure/non-disclosure information for managing a user who conducts a retrieving and disclosure or non-disclosure information of a table, and an information management dictionary having a disclosure condition for managing a user who conducts retrieving and each data item in the table. In addition, server information for managing information of another server is employed to conduct duplicating data or the information management dictionary.

Abstract: A heat exchanger tube manufacturing method to manufacture heat exchanger tubes in a production line. The method includes the steps of molding a plurality of dimples in a plate material, which is payed out continuously, folding back the molded plate material along an axis extending in the direction in which the plate material is payed out to form the molded plate material into an intermediate tube body and cutting the intermediate tube body into parts of a predetermined length.

Abstract: A heat exchanger tube manufacturing method which is adapted to manufacture heat exchanger tubes accurately as the sealability thereof displayed when they are inserted into heat exchanger bodies is maintained, and which is used on a production line, having a dimpling step of molding a plurality of dimples in a plate material, which is payed out continuously, so as to form the plate material into a molded plate material, a tube body manufacturing step of folding back the molded plate material around an axis extending in the direction in which the plate material is payed out, so as to form the molded plate material into an intermediate tube body, and a step of cutting the intermediate tube body into parts of a predetermined length, the dimpling step including providing the plate material with non-molded sections, in which the dimples are not molded, at predetermined intervals, the cutting step including cutting predetermined parts to be cut set on the non-molded sections.
