Abstract: Provided are a resin composition controlled such that after keeping a shape thereof under a severe environment as in high-temperature hot water or in hot water under chemically severe condition, such as an acidic or basic condition, etc., for a fixed period of time, it is quickly decomposed; and a structure thereof.

Abstract: This invention provides a method for improving gene expression efficiency specifically in motor neurons and/or in sensory neurons and an enhancer consisting of the following DNA (a), (b), or (c): (a) DNA consisting of the nucleotide sequence as shown in any one of SEQ ID NOs: 1 to 4; (b) DNA consisting of a nucleotide sequence derived from the nucleotide sequence as shown in any one of SEQ ID NOs: 1 to 4 by deletion, substitution, or addition of one or more nucleotides and capable of improving gene expression efficiency in motor neurons; or (c) DNA consisting of a nucleotide sequence capable of hybridizing under stringent conditions to a nucleotide sequence complementary to the nucleotide sequence as shown in any one of SEQ ID NOs: 1 to 4 and capable of improving gene expression efficiency in motor neurons.

Abstract: A spacer (10) to be inserted into a dash silencer comprises a cylindrical hollow body (12), a first flange (13) extending radially outward from one of the ends of the body, a second flange (a contact flange) (14) extending radially outward from the other end of the body, and a plurality of engagement pawls each extending from the outer surface of the other end of the body toward the first flange. The engagement pawls include a resilient engagement pawl (17) and a rigid engagement pawl (18). The contact flange has an outer diameter slightly larger than the hole diameter of a mounting hole formed in the dash silencer to allow the spacer to be readily inserted into the mounting hole. Each of the engagement pawls (17, 18) has an outer shape expanding upwards outward to allow the spacer to be inserted into the mounting hole while aligning the respective centers of the spacer the mounting hole with one another.

Abstract: A plastic package with a fastener composed of a plastic package body and a sealing sheet disposed in an internal portion of the package, wherein a first side of the package body and the sealing sheet are capable of being opened and closed by the fastener at an inlet portion of the package body, and a second side of the package body and the sealing sheet are sealed and the first side of the package body and the sealing sheet are bonded by peelable bonding portion(s) at a more internal side and/or external side of the package than the fastener. The package of the present invention has excellent filling, opening and resealing abilities even if the contents are liquid, as well as excellent pressure resistance.

Abstract: A plastic zipper has a pair of female (11, 13) and male (21, 23) hooks formed on the surface of plastic films, 10, 20 and an inside of the male hooks are engaged with a pressing rib 31 to form a sealing section independent of a locking section constituted by the pair of female and male hooks. The zipper permits good hermetic sealing performance, easy opening, and easy reseating.

Abstract: The present invention is a two-compartment syringe which may contain a medical substance, such as a freeze-dried powder, and a solvent separately. When used, the medical substance and solvent are mixed for injection. A silicone coating is used inside the syringe barrel. The syringe is further provided with finger hooks to enable use of the syringe with one hand.

Abstract: An apparatus for manufacturing a tubular film from thermoplastic resin which comprises an extruder fitted with an annular die; a mechanism for introducing air into a tubularly inflated film; a cylindrical water cooler which consists of an annular cooling water reservoir disposed at the upper part, a cap member covering said water cooling reservoir, a vacuum sizing chamber positioned below said cooling water reservoir, an annular cooling water discharging chamber located below said sizing chamber and an annular vacuum suction chamber bored with a suction port so as to remove residual water, the underside of said cap member and the upper side of said sizing chamber defining an annular passageway of cooling water; a mandrel received in the cylindrical water cooler so as to internally cool the tubular film; and a film take up mechanism.
