摘要:
When a dry analysis element contained in an element cartridge to be loaded in a sample tray of an automatic analysis apparatus projects from a take out port, the element is returned to its proper position, thereby preventing conveyance failure and information readout failure, with the result that higher operation reliability is ensured. An element mounting portion is equipped with a correcting means, such as a restricting projection. The correcting means contacts and pushes a dry analysis element which projects from an element cartridge back to its predetermined position therein, in association with a loading operation of the element cartridge.

When a function designated by operation of a function setting switch has been executed, a shortcut icon of instructing to start up the function is automatically registered to a stand-by screen. When a user operates the shortcut icon registered to the stand-by screen, the function assigned to the shortcut icon starts up, whereby even if the user operates a wrong operation key and calls out an undesired function, the function that has been executed just before can be called out instantly and in a simple manner.

A non-austemper-treated spheroidal graphite cast iron obtainable without being subjected to an austemper treatment. The non-austemper-treated spheroidal graphite cast iron has a tensile strength of 650-850 MPa and an elongation of 7.0-14.5%. In the non-austemper-treated spheroidal graphite cast iron, V-notch material has a fatigue limit of 290 MPa or more. The non-austemper-treated spheroidal graphite cast iron has well-balanced mechanical properties both in tensile strength and elongation and improved tensile strength and elongation than conventional one.

There is provided an air filter, which has a long lifetime and permits to capture effectively carbon particles and reduce costs. The air filter has the first filter layer 11 impregnated with oil and the second filter layer 12, which is provided on the downstream side of the first filter layer 11 and serves as a lipophobic layer having an oil-repellent property. The filter material of the first filter layer 11 has a higher density than the filter material of the second filter material 12.

An IC socket for the fine pitch IC package includes a socket body having an opening for guiding the IC package, an insulation base having a plurality of through-holes corresponding to the external terminals of the IC package, the contact pins placed in the through-holes, and a cover member for applying a predetermined pressure to bring the external terminals of the IC package and the contact pins into contact with one another. Each of the contact pins is formed with a first plunger including a terminal portion to be in contact with the external terminal of the IC package, a wider portion whose width is larger than the width of the terminal portion and the shaft whose width is equal to or smaller than the terminal portion, the coil spring, and the second plunger having a U-shape section, to be connected with the contact terminal of external circuit.
