A cap attaching/detaching deviceis a device for attaching or detaching a capin which a screw portion is formed to or from a test tubeby rotating the cap. A cap grip portiongrips the cap. A rotation mechanismattaches or detaches the capto or from the test tubeby rotating the capby rotating the cap grip portion. The rotation mechanismhas an axial portion, and a nut portion. The axial portionhas an outer peripheral surface on which a screw threadis formed. The nut portionhas an inner peripheral surface on which a screw grooveto be screwed into the screw threadof the axial portionis formed, and rotatably holds the axial portionin a fixed state. A pitch of the screw threadis the same as a pitch of the screw portion formed in the cap

A solid-liquid boundary detection device 20 is a device for detecting a boundary 141 between a solid and a liquid in a test tube 14, and includes a surface illumination 21, an imaging unit 22, and a boundary detection processor 31. The surface illumination 21 illuminates the test tube 14 from outside. The imaging unit 22 is arranged on an opposite side of the test tube 14 from the surface illumination 21, and captures an image including the boundary 141. The boundary detection processor 31 detects the boundary 141 from the image captured by the imaging unit 22.

[PROBLEM] In space-conservative fashion, at low cost, and with high efficiency, to carry out absorption of gas produced at the interior of a battery. [SOLUTION MEANS] Secondary batteryis provided with casein which positive electrodeand negative electrodeare sealed together with electrolyte, and with explosion prevention valvefor allowing escape of high-pressure gas present at the interior of casewhen pressure within caserises; and is further provided with gas absorberorfor absorbing high-pressure gas. Gas absorber, includes gas-absorbent materialand capsule, which comprises hot-melt material, and is provided within case, this capsuleincluding, at the interior thereof, gas-absorbent material. Furthermore, gas absorber, which may be provided outside case, may include gas-absorbent material; cartridge casewhich houses, at the interior thereof, gas-absorbent material; gas inlet valvefor causing high-pressure gas to flow thereinto; and gas outlet valvefor causing high-pressure gas to flow out therefrom.

At the time of measurement of a sample, before a sample is introduced into a graphite tube, signal voltages which would be detected by a photomultiplier in connection with all programmable combinations of atomizing temperatures of a graphite tube, widths of entrance and exit slits provided in a spectrometer, and wavelengths into which the light is to be decomposed by the diffraction grating are stored in memory beforehand. At the time of measurement of a sample, an amplification factor of the photomultiplier is controlled by a negative high-voltage controller according to measurement requirements, or measurement is performed after an optimum detector signal voltage is set by controlling the amplification factor of the detector signal output from an amplifier.

A a seal ring is made of a synthetic resin and has opposite ends. The seal ring has been imparted with shape-retentive property so that the seal ring is crossed at portions thereof located inside the opposite ends. The seal ring preferably has a smaller radius of curvature around the crossed portions and also around a portion thereof located diametrically opposite the crossed portions than around remaining portions thereof. Desirably, the seal ring may be in a substantially elliptic shape. The seal ring may preferably be symmetrical relative to a line extending between the crossed portions and a portion thereof located diametrically opposite the crossed portions.
