Disclosed is a fire extinguisher (100) comprising a fire extinguisher cylinder (10) for a fire-extinguishing agent. The fire extinguisher cylinder (10) comprises a mouth portion as an opening, a shoulder, a cylindrical body portion, and a bottom portion and is shaped with use of a resin provided with no joint. In addition, the body portion in the fire extinguisher cylinder (10) has a thickness from 1 mm to 5 mm, and a crystallinity of the resin is from 13% to 30% at the sites other than the mouth portion and the bottom portion. Accordingly, the fire extinguisher (100) is lightweight and does not rust. Further, the fire extinguisher (100) has high strength or high pressure resistance.

Disclosed are an apparatus for the identification of a ribonucleic acid, whereby not only the molecular weights of digestion products, from which nothing but the nucleic acid residue composition can be understood, but also nucleic acid residue sequence data is obtained from a product ion mass set and thus the identification reliability for the individual digestion products can be remarkably improved; a method for the identification of a ribonucleic acid; and a program and system for the identification of a ribonucleic acid. The method as described above comprises: searching for nucleic acid sequence database by using a fragment mass set indicating the molecular weights and inner structural data of individual oligonucleotides that are obtained by tandem mass spectrometry on digested oligonucleotides formed by chemically or enzymatically cleaving a ribonucleic acid; scoring candidate sequences; among candidate sequences showing the highest scores, referring those showing scores exceeding the threshold as identified sequences; and using these identified sequences in mapping on nucleic acid sequence database including genomic sequences.

A cation-exchange membrane for electrolysis which comprises a fluoropolymer having ion-exchange groups and a porous base. It is characterized by having, on the anode-side surface of the membrane, protrusions comprising a polymer having ion-exchange groups. It is further characterized in that: when the average value of the heights of the tops of the protrusions from the anode-side surface of the membrane is expressed as h (μm), then 20≦h≦150; when the density of the protrusions distributed is expressed as P (protrusions per cm2), then 50≦P≦1,200; when the average proportion of the areas of those bottom parts of the protrusions which are on the same level as the anode-side surface of the membrane to the area of the anode-side surface of the membrane is expressed as S (cm2/cm2), then 0.001≦S≦0.6; and when the average proportion of the areas of the top parts of the protrusions to the area of the anode-side surface of the membrane is expressed as T (cm2/cm2), then T≦0.05.

A waste disposal apparatus includes a lid lock mechanism for locking a lid and an upper part of a waste accommodating main body together in a coupled state, and a main body lock mechanism for locking the upper part and a lower part of the waste accommodating main body together in a coupled state. The waste disposal apparatus further includes a lid unlock mechanism in which a direction of an operation of unlocking the lid lock mechanism is different from that of an operation of opening the lid, and a main body unlock mechanism in which a direction of an operation of unlocking the main body lock mechanism is different from that of an operation of opening the upper part of the waste accommodating main body.

A method capable of stirring a liquid sample and a reagent promptly and easily includes the following steps (A) and (B). In step (A), using a cell including: a liquid sample retaining section having a plurality of particles; and a liquid sample supply inlet, a liquid sample containing an analyte is supplied from the liquid sample supply inlet to the liquid sample retaining section. In step (B), the liquid sample and a specific binding substance capable of specifically binding to the analyte are stirred by the movement of the particles caused by the flow of the liquid sample in the cell resulting from the supply of the liquid sample, to obtain a liquid mixture. The electric charge of at least the surface of the particles and the electric charge of the specific binding substance have the same polarity in the liquid mixture.
