Abstract: A vessel 1 comprises a container 2 for storing a sample solution containing a volatile substance and a stopper 3. The stopper 3 is formed with a through-pore 3a at the center, through which a vaporized volatile substance is discharged with exhaust gas. The stopper 2 is formed with a gas inlet port 3b and a gas outlet port 3c at the upper and lower edges, respectively, and a groove 3d connecting the both ports 3b and 3c at the side surface. On reducing pressure in the container 2, an external gas is blown into the container 2 from the gas outlet port 3c through the groove 3d at high speed and spirally rotates by centrifugal force along the inner wall of the container 2. This kicks up the sample solution to stir it, increasing the surface area of the solution and thus promoting vaporizing of the volatile substance.

Abstract: To reduce the transmission of vibrations from a body frame to a rotary switch, thereby preventing any trouble in the rotary switch and reliably maintaining the function and performance of the rotary switch. A side stand device includes a side stand bracket mounted on the body frame. A side stand is rotatably mounted through a pivot shaft to the bracket, and a rotary switch is provided in coaxial relationship with the pivot bolt through a securing bolt. A sheet is interposed between the rotary switch and the pivot bolt, and a tube and a sheet are interposed between the rotary switch and the securing bolt. The sheets and the tube are formed from rubber members. A cushion member is interposed between an engaging member of an inner rotor in the rotary switch and a locking hole of the side stand. The cushion member is formed from a rubber member.

Abstract: Compactness is enhanced while retaining the performance, noise deadening characteristic and engine output. The ratio of the distance, a, from a gas outlet end, p, of an exhaust pipe to an inner wall of a rear partition wall to an inside diameter ∅A of the exhaust pipe is set in a relation of 0.6≦(a/∅A)<1.2, while the ratio of the distance, b, from a gas inlet end, q, of a tail pipe to an inner wall of a front partition wall to an inside diameter ∅B of the tail pipe is set in a relation of 0.4≦(b/∅B)<1.2, to afford a silencer having an optimum combination of engine output characteristic and compactness while retaining a noise deadening effect.

Abstract: Novel compounds, called chloropolysporins B and C, and salts thereof have antibiotic properties and would appear to be members of the class of glycopeptide antibiotics containing chlorine. They may be produced by cultivating a suitable strain of microorganism of the genus Micropolyspora, especially Micropolyspora sp. SANK 60983 (FERM BP-538). They may be combined with conventional pharmaceutically acceptable carriers or diluents for therapeutic use or incorporated into edible excipients, such as feed or water, for use as a growth-promoting agent, especially for farm animals.
