Abstract: A vector having a region encoding a cold shock protein gene mRNA-origin 5?-nontranslated region, characterized in that the 5?-nontranslated region has a mutation having been transferred therein so as to change the distance of the stem structure formed by the region.

Abstract: A high-performance gasket (1) capable of coping with a reduction in size and developing a sealing property without producing a squeeze-out at the time of attachment and using a material having a hardness range of 30 to 80 degrees (JIS durometer type A), wherein the requirement of W1/W0<0.9 is satisfied where the bonding width of a base part (1a) is (W0) and the width thereof at a position half a height from the bonding part of the base part (1a) to the tip end of a main bead part (2) is (W1), the requirement of 1.15<H/W0<1.80 is satisfied where the height from the bonding part of the base part (1a) to the tip end of the main bead part (2) is (H), the requirement of L/W0>=3 is satisfied where the length of the non-bonded portion of the base part (1a) around the cross-section thereof excluding the bonded portion is (L), and the compressibility of the gasket when compressed is 13.5% or higher.

Abstract: In order to make it possible to previously specify which of two members the rubber-like elastic part pinched between the two members attaches to, and to improve workability of rework or the like, an attachment member specifying structure is provided in the rubber-like elastic part so that the rubber-like elastic part is surely detached from one member and attached to the other member at a time of moving the two members apart from each other, preferably by forming a contact area with one member in the rubber-like elastic part smaller than a contact area with the other member, by forming a surface treated portion by matte finishing or the like in a contact area with one member in the rubber-like elastic part, or by forming a projection-like spring portion elastically pressed to one member so as to achieve a spring effect.

Abstract: In a cover gasket for a hard disc apparatus in which a cover and a rubber are later bonded by using an adhesive agent, in order to prevent running out of the adhesive agent and peeling off of the rubber as much as possible, a recess portion for storing the adhesive agent is provided on a bonding surface of the cover or the rubber, and the bonding is executed in a state of storing the adhesive agent in this recess portion, the recess being provided in the center in the width direction of the bonding surface of the rubber, or being provided in end portions in the width direction of the bonding surface of the rubber.

Abstract: A sealing gasket for a hard disc drive unit is made by molding an annular sealing member over an annular metal plate. The mold is, provided with an annular cavity and gatings to the cavity including sprue gates and film gates. The gatings are arranged radially outwardly of the cavity to ensure that any flashes or burrs resulting from the presence of the gatings are situated radially outwardly of the sealing member.
