Title: Extraction of dna derived from microorganism in soil and environment for treating waste
Inventor: FUKUDA HIROAKI
IPC: C12N15/09
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To simply and rapidly obtain a DNA sample which does not contain humic acid or the like which inhibits the PCR reaction by extracting DNA derived from microorganisms existing in an environment containing humic acid by adding a water soluble humic acid-adsorbing agent upon destroying microorganisms in an aqueous solution.

IPC: G03G21/00
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus for efficiently holding data. SOLUTION: This image forming apparatus reads the model data of a recording apparatus 104, so-called device ID from the recording apparatus 104 through a parallel interface (S302) and judges whether a P-ROM for domestic delivery is mounted from the MODEL data of the read device ID (S303). If the P-ROM for the domestic delivery is mounted, 0 is set to a variable Flag for holding destination data (S304) and, if the P-ROM for domestic delivery is not mounted, it is judged that a P-ROM for North America delivery is mounted and 1 is set to the variable Flag for holding dispatch data (S305). By this constitution, an image processor can judge the destination of the recording apparatus, that is, the destination of the image forming apparatus itself by looking the value of the variable Flag in the subsequent processing.

Title: Document preparation device and character recognizing method used therefor
Inventor: AMO MITSUHIRO
IPC: G06K9/46
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To recognize a complicated character such as a rotated character, a deformed character, and a character having a line kind other than a straight line and to output the recognized character exactly in the shape which is inputted. SOLUTION: When the rotated character is handwritten and inputted, the input character is normalized to easy-to-recognize size and the original size is stored in this case (A13). The rotational angle of the input character is decided and the normalized input character is rotated into a recognizable shape (A14). This rotated input character is regarded as an object of recognition and recognized (A15), and the recognition result is inputted (A23). In this case, the recognized character obtained as the recognition result is converted to the size when inputted (A21) in deformation output mode (A20), and rotated to the angle when inputted to output (A23).

Abstract: PROBLEM TO BE SOLVED: To provide a can top protecting cover for packing which does not hurt fingers even though a heavy can is carried for a long time and is helpful for reducing a cost. SOLUTION: A liner piece 10e is turned down toward the reverse side of a part 10d to be corded. The part 10d to be corded of a can top protecting cover 10 for packing and the liner piece 10e are put together at the reverse side of a plastic tape 12. Therefore, on carrying a paint can 11, the tape 12 is gripped so as to be wrapped in with fingers applied to the reverse side of the liner piece 10e, and the paint can 11 is lifted up. As a result, an apparent thickness of the tape 12 is increased at the reverse side thereof by a combined thickness of the part 10d to be corded and the liner piece 10e. Thereby, the lined part of the tape 12 is made to be gripped easily, and the fingers carrying the heavy paint can 11 are hardly injured. Since the protecting cover 10 is made up in a simple structure comprising the part 10d to be corded and the liner piece 10e, the cost of the protecting cover 10 can be reduced.
