摘要:
The invention provides a high capacity binary shuttle vector having T-DNA region and Ri ori and capable to integrate a large genome fragment in it; a genomic library having the ability to transform a plant, especially monocotyledonous ones; a plant transformed with the high capacity binary shuttle vector; and a method of searching for a useful gene by use of the above vector. The present high capacity binary shuttle vector can introduce a large genome fragment of 10 kb or more, easily, efficiently and stably into a plant, especially monocotyledonous ones under those conditions in which the rearrangement or deletion of these genome fragments does not occur. The invention also provides some other vectors derived from the above Ri ori driven vectors, which can integrate circular genome library plasmids with a lox site, or which can efficiently transform plants with genes of arbitrary expression properties. The invention includes also the assessment method for the functions of genome fragments inserted in the above vectors by complementation assay. In addition, a useful gene or gene complex can be efficiently examined so its isolation is also made easy.

A facsimile machine is connected to another facsimile machine by a telephone line and to a computer by an exclusive line. The facsimile machine has a computer-linked mode and an ordinary facsimile mode. If the facsimile machine is in the computer-linked mode, the image data transmission between the facsimile machine and the computer is performed based on an instruction command from an operator of the computer. If the facsimile machine is in the ordinary facsimile mode, the image data transmission between the facsimile machine and another facsimile machine is performed in an ordinary facsimile transmission manner. When an instruction command comes from the computer, the facsimile machine sends a response signal (or message) to the computer in answer to the instruction command. Thus, the facsimile machine operates under the supervision of the computer. This improves the control reliability.

A method for transmitting data from each of n transmitting devices (1) to (n) is provided. According to this method, the data is transmitted with each of a plurality of transmission cycles being one group. Each of the plurality of transmission cycles includes a transmission unit and a first transmission rest period, and the transmission unit includes at least n transmission periods and at least (n-1) second transmission rest periods. The transmission periods and the second transmission rest periods are alternately repeated. The method includes the step of transmitting send data and determination data for determining whether or not two given transmission periods belong to an identical transmission cycle during each of the at least n transmission periods, where n is a positive integer.

A method of corrugating a metallic pipe which achieves an increase in the limit of tube expansion ratios. First, a heated part is formed by heating a local part of an outer periphery of a pipe in a circumferential direction by a high frequency coil. Next, the heated part is located within a forming surface of a forming die, and an axial compressive stress is applied to the pipe. Thus, the heated part is expanded while restricted by the forming surface. Therefore, even when the axial length of the heated part is increased, formability is stabilized and the tube expansion ratio can be raised.

The present invention provides nucleic acid markers for rice blast resistance genes, which are isolated from the rice genomic DNA, are DNA sequences having a total length of up to 2 kb, with two identical sequences of at least ten bases at the both ends thereof and are located within a distance of 2.0 cM from rice blast resistance genes Pi-b, Pi-ta or Pi-ta.sup.2 . According to the present invention, it becomes possible to easily isolate rice blast resistance genes and related genes from rice cultivars containing Pi-b, Pi-ta.sup.2 or Pi-ta, thus promoting development and breeding of superior cultivars. It becomes also possible to easily carry out a resistance test of rice. This will open up the way to create new resistance genes.

A first method for manufacturing a solid oxide film having a highly densified solid oxide film having a small thickness and an improved electric conductivity; and a second method for manufacturing a solid oxide fuel cell in which a solid oxide film formed on an air electrode or a fuel electrode is manufactured by the first method. The solid oxide fuel cell according to the present invention is capable of generating a high power. The solid oxide film is formed on a substrate in such manner that a solid oxide material is sprayed on the substrate to form a sprayed solid oxide film thereon; Then a solution of metal compound including at least one metal selected from a group of manganese, iron, cobalt, nickel, copper and zinc is impregnated into the sprayed solid oxide film; and the sprayed solid oxide film is subjected to a heat treatment in order to increase an airtightness of the film. It may be possible to use a material for spraying, in which 1.about.10 parts by weight of an oxide of said metal is contained, instead of the impregnation, or to obtain a material for spraying by mixing the compound powder containing the metal and the solid oxide material in a spray gun via separately arranged powder supply devices.
