Abstract: PURPOSE:To extend the range of a kind of materials to be joined by joining soft intermediate material to first material to be joined, then, joining second material to be joined to the intermediate material and giving the frictional force to the joining face in a vacuum or inert atmosphere to carry out joining. CONSTITUTION:The materials 34 and 35 to be hardly joined are subjected to friction joining to each other. One end of the soft intermediate material 36 is abutted on the first material 34 to be joined and the vicinity of the abutted joining face if surrounded airtightly in an airtight chamber 10 and the inside thereof is maintained in the inert atmosphere containing the vacuum or inert gas or <=10ppm oxygen and the frictional force is given to the joining face to carry out joining. Continuously, the second material 35 to be joined is abutted on the other end of the intermediate material 36. Joining is then carried out in the same way by using the airtight chamber 10. The joining face is activated by the physical activation method and then, joining is carried out. By this method, plastic deformation and deterioration of the materials can be prevented.

Abstract: PURPOSE:To reduce the cost by removing non-KANJI(Chinese character) characters from a partial string of the specific number of characters which are behind a position of non- KANJI-to-KANJI change in a character string read out of a text storage means, and obtaining a degeneracy form, and providing an inscription fluctuation information extracting means and pointing out inscription fluctuations. CONSTITUTION:A text is read out of the text storage means, character by character, and a character, in order and a character kind decision means 2 decides HIRAGANA(cursive form of Japanese syllabary), KATAKANA(square form of Japanese syllabary), KANJI, numerals, alphabet, etc. Then positions of changes from non-KANJI characters to KANJI characters are recognized by a character kind change position recognizing means 3 and stored in a storage means 4. When the original inscription character string of four characters starting at the change position of character kinds is all stored in the record of a different- inscription candidate in the means 4, a degeneration acquisition means 5 deletes non-KANJI to obtain the degeneration form of the remaining two KANJI characters. Different inscription candidates which are equal in degeneration form and different in original inscription are regarded as the relation of fluctuations of inscription, extracted by an inscription information extracting means 6, and displayed on a display device 14. Consequently, the need for a large- capacity dictionary is eliminated and the cost is reduced.

CONSTITUTION:If the crankshaft of an internal combustion engine is used as a rotary shaft 10, an adjusting means 40 is suitably set so that a second housing 43 is completely locked when the rotational speed of the second housing 43 reaches a predetermined rotational speed, and accordingly, the motion initiating point of a torque limiter 50 is set such that a carrier 24 is changed over so as to be freely rotatable relative to the second housing 43 and an outer ring 22. Then, it is possible to limit the rotation of the rotary member 30 so that the rotational speed of the rotary member 30 is not increased so much even though the rotational speed of the crankshaft is increased. Accordingly, it is possible to transmit a necessary but minimum power to the accessory with no excessive load being applied, and it is also possible to reduce the burden of the internal combustion engine on the drive side.

Filed: 1998-11-16
Abstract: PROBLEM TO BE SOLVED: To increase the susceptibility of epithelial cells to viral infection and increase the gene transfer efficiency to epithelial tissues when using viruses and viral vectors by increasing transepithelial permeability of the epithelial tissues. SOLUTION: The transepithelial permeability of epithelial tissues, containing epithelial cells (preferably an airway epithelial tissue, e.g. a bronchial tissue, a tracheal tissue or an alveolar tissue) is increased to thereby increase the susceptibility of the epithelial cells to viral infection. Furthermore, the epithelial cells are proliferated by bringing the epithelial cells into contact with a proliferative factor (preferably a growth factor) to thereby achieve an increase in the susceptibility. Furthermore, the increase in the susceptibility can be achieved by bringing the cells of the epithelial tissues into contact with a tissue permealizing agent [preferably a hypotonic solution, an ion chelator (e.g. EGTA), a cationic peptide (e.g. poly-L-lysine), etc.].
