摘要:
The process of the present invention comprises the steps of (a) a step of dissolving a condensed tannin powder in an aqueous alkaline solution, (b) a step of admixing an aqueous aldehyde solution with the aqueous solution obtained in the step (a), (c) a step of adding the aqueous solution obtained by the above step (b) to a hydrophobic solvent containing a polyether type nonionic surfactant under heating and stirring to disperse the aqueous solution in the form of droplets in said hydrophobic solvent and (d) evaporating water components from the above-mentioned droplets to form a spherical and gelled insoluble tannins. Water content of the gel can be widely controlled as 5 to 90% as compared with the conventional adsorbent and the network structure and molecular space are changed depending on the size of the metal ion to be adsorbed so that a gelled insoluble tannin which can increase an adsorption capacity of metals can be obtained. Also, when it is used as an adsorbent, it is not necessary to be pulverized and a gelled insoluble tannin having a desired particle size and water content can be obtained.

A vibration-absorbing tube includes a bellows composed of a thin metal and a fiber braid reinforcement covering the bellows. The outer face of the bellows is covered (filled) with a buffer material, or rubber, from the bottom of troughs of the bellows to a height that is 0.5 to 2.0 times the height of ridges of the bellows, and the fiber braid reinforcement has a braided angle of 30° to 50°, preferably, of 35° to 45°. Gaps in the fiber braid reinforcement may be impregnated with a curable resin or rubber.

An oral composition comprising trifluoromethionine as an effective component is provided as a useful oral composition for preventing and/or treating intraoral diseases such as bad breath, periodontal disease, alveolar pyorrhea, etc., which is safe even if daily used.
摘要:
A coating system selecting kinds of coating heads and operation sequences with no errors even when two or more kinds of coating heads are used in exchange in a single coating line. The coating system uses an automatic discriminating device which automatically discriminates at least kinds of a plurality of coating heads used in exchange in a single coating line, thereby discriminating the kind of the coating head which is set in the coating line.

This invention relates to a facsimile apparatus for implementing an automatic transmission of a meaningful response to a document received from the facsimile apparatus on the other terminal of a communication line. Thereby, the addresser of the document will be notified of the receipt of the document or a receiving condition of the addressee when the transmission of the response is postponed. Further the immediate answer to the document will be received by the addresser of the document. The facsimile apparatus comprises a mode conversion unit for converting its mode from the reception operation into the transmission operation and vise versa upon completion of the reception and completion of the transmission respectively; therefore the transmission/reception of the document and the response will be conducted at the signal communication.
摘要:
An apparatus and method for page-retrieval for use with an electronic display, especially suited for so-called electronic books, wherein a current relative position of a current page of the book and the number of times a page has previously been displayed are graphically displayed. A document image is stored in a document image storage unit and the document image is displayed on a computer screen. A number of display times storage unit stores the number of times each page has been viewed by a user. A relative location image control unit determines the relative location within the book image of a currently displayed page and the electronic book is displayed on the screen showing a visual indication of the relative position of the currently displayed page. The pages of the electronic book are color shaded by a number of display times image generation unit to give a visual indication of the relative number of times each page has been displayed to allow frequently displayed pages to be quickly located by a user. A marker can also be displayed on the screen to indicate pages marked by a user.

Triglycerides are stabilized by preventing hydrolysis of triglycerides. A method for stabilizing triglycerides comprises controlling a polymorphic composition of the triglycerides so that the polymorphic composition includes either 10 to 30% by weight of .alpha. type, 20 to 40% by weight of .beta.' type and 40 to 60% by weight of .beta. type or 35 to 55% by weight of .beta.' type and 45 to 65% by weight of .beta. type.
摘要:
Provided is a telescopic shaft having a coated section that reduces sliding resistance, with fluctuation of the sliding resistance according to sliding position of the telescopic shaft being reduced. A female shaft 16B is fitted onto a male shaft in a state of interference, and by causing the male shaft 16A to slide back-and-forth a specified number of times in the axial direction with respect to the female shaft 16B while applying, for example, a load in a direction that bends the male shaft 16A with respect to the female shaft 16B, friction heat is generated between side surfaces 411 of grooves 41 in the female shaft 16B and the coated section 61, which heats the coated section 61 and causes the coated section 61 to expand along the entire length in the axial direction of teeth 51 of the male shaft 16A. Therefore, the coated section 61 plastically deforms along the entire length in the axial direction of the teeth causing compressive strain to occur. By causing the male shaft 16A to slide back-and-forth with respect to the female shaft 16B in this state, the grooves 41 of the female shaft 16B and the teeth 51 of the male shaft 16A are uniformly in contact along the entire length in the axial direction, and thus sliding friction becomes constant along the entire length of the sliding range.

A method and apparatus for playing a plurality of different video poker games using a microprocessor, a player input device and a display device including the ordered steps of displaying a plurality of different poker games on the display device, selecting one of the plurality of different poker games by means of the player input device and playing the selected one of the plurality of different poker games using the display device and player input device.
摘要:
The present invention provides a method which can enhance the precision of identification of bacterial species using a T-RFLP method and achieve, by itself, the identification of bacteria constituting a bacterial flora and the tracing of distribution changes thereof. The present invention provides a method for analyzing a bacterial community including: amplifying DNAs extracted from a bacterial community by PCR using 16S rRNA genes as templates and fluorescently labeled primers; cleaving the amplification products with a restriction enzyme to thereby obtain sample PCR fragments; electrophoresing the sample PCR fragments together with size standard PCR fragments; and comparing the mobilities thereof to thereby determine the sizes of the sample PCR fragments, wherein PCR fragments amplified by using, as a template, a 16S rRNA gene derived from a bacterium contained in the bacterial community to be analyzed are used as the size standards.
