Abstract: A safe and easy handling of a chemical-liquid circuit having various components. The opening/closing unit drive mechanism includes an opening/closing unit holder which detachably holds an opening/closing unit which includes a housing having flow channels and a piston for opening and closing the flow channels which is movably provided to the housing, a hook to be engaged with the piston of the opening/closing unit, which is disposed leaving a space from the opening/closing unit holder, and a linear motion mechanism which moves the hook back and forth. The opening/closing unit holder is movably supported between a first position at which the piston is engaged with the hook and a second position at which the piston is not engaged with the hook.

Abstract: An injection system has: a gasket having multiple engaging claws, and a distal end portion having across-sectional shape in which a length in a height direction of the cross-sectional shape is longer than a length in a width direction; a ram engaged with the gasket; a cylinder into which the gasket is inserted; and an injection device configured to move the ram and injecting a chemical solution in the cylinder. Each of the engaging claws includes an inner surface which defines a hole having an inlet with an enlarged diameter and inclined in a direction away from a perpendicular line passing through a center of the hole. The engaging claws are displaced between a widened position and a narrowed position. Two engaging claws aligned in the height direction have the same shape and size, and two engaging claws aligned in the width direction have the same shape and size.

Abstract: There is provided a speaker device 1 having a speaker unit 10 and an enclosure 30 in which a plurality of rod-shaped bodies 31 is integrally bonded to each other and which is arranged in a space behind the speaker unit 10. Thus, a sound wave output from the speaker unit 10 to the rear side thereof can be more effectively damped.

Abstract: An injection system has: a gasket having a plurality of engaging claws, wherein each of the engaging claws includes an inner surface S1 which defines a hole H having an inlet with an enlarged diameter and an outer surface S2 inclined in a direction away from a perpendicular line P passing through a center of the hole H, and the engaging claws are to be displaced between a widened position and a narrowed position; a rain to be inserted into the hole H so as to engage with the engaging claws; a cylinder, into which the gasket is to be inserted, contacting the outer surfaces S2; and an injection device configured to move the ram forward and injecting a chemical solution in the cylinder. An annular groove which serves as a starting point of deformation of the engaging claws is formed on the gasket.

Abstract: A novel nucleic acid fragment which has an high activity to promote expression of a structural gene located downstream thereof, and a method for promoting expression of the structural gene located downstream thereof using the nucleic acid are disclosed. A nucleic acid fragment having the nucleotide sequence shown in SEQ ID NO:1 in the Sequence Listing, and nucleic acid fragments having the same sequence as shown in SEQ ID NO:1 except that one or more nucleotides are substituted or deleted, or one or more nucleotides are inserted therein or added thereto, which have activities to promote expression of a structural gene located downstream thereof were provided.

Abstract: Nucleic acid fragments having activities to prominently promote expression of structural genes located downstream thereof are disclosed. The nucleic acid fragment according to the present invention is an isolated nucleic acid fragment having the nucleotide sequence shown in SEQ ID NO: 1 in Sequence Listing or an isolated nucleic acid fragment (excluding the nucleic acid having the nucleotide sequence shown in SEQ ID NO: 3 in Sequence Listing) having the same nucleotide sequence as shown in SEQ ID NO: 1 except that one or a plurality of nucleotides are substituted or deleted, or except that one or a plurality of nucleotides are inserted or added, which has an activity to promote expression of a structural gene located downstream of said nucleic acid fragment.

Abstract: A novel DNA fragment capable of enhancing the expression level of a gene. The DNA fragment according to the present invention contains a nucleotide sequence from one of the nucleotides at around positions 1- to 152 to one of the nucleotides at around positions 259 to 374 in the sequence represented by SEQ ID NO:1 and is capable of enhancing the expression level of a gene.

Abstract: A method for expressing a foreign gene, by which the foreign genes can be expressed more strongly than by the conventional methods, as well as a recombinant vector therefor, is disclosed. In the method for expressing a foreign gene according to the present invention, the foreign gene is inserted into a site downstream of a promoter and the foreign gene is expressed in a cell, wherein a plurality of intron-originated DNA fragments which are the same or different and are capable of promoting expression of foreign genes are inserted into one or more sites upstream of the foreign gene, and said foreign gene is expressed.

Abstract: A method for artificially changing the composition of phospholipids produced by cells is disclosed. According to the method of the invention, the host cell is transformed with a recombinant DNA having an antisense gene of phospholipase D gene, which antisense gene is expressed in the host cell to produce a mRNA that hybridizes with mRNA of phospholipase D gene in the host cell thereby inhibiting expression of the phospholipase D gene.

Abstract: Disclosed is a novel DNA which can promote expression of foreign genes and which has a nucleotide sequence different from those of known DNAs that promote expression of foreign genes. The present invention provides an isolated DNA fragment having a nucleotide sequence shown in SEQ ID NO. 1 in Sequence Listing or having a nucleotide sequence which is the same as the nucleotide sequence shown in SEQ ID NO. 1 in Sequence Listing except that one or a plurality of nucleotides are added, inserted, deleted or substituted, the latter nucleotide sequence having a function to promote expression of a gene downstream thereof.
