Abstract: A pad tray includes a base portion and a recessed region that is formed in the front side of the base portion and is for accommodating an electrode pad, the recessed region having a bottom region and a sidewall region that extends up from the bottom region and is provided so as to surround the electrode pad.

Abstract: Both application of centrifugal force to a biosensor and electrical connection with an electrode of the biosensor can be achieved with a simple structure. The electrode of the biosensor and a measuring part are connected without aligning a rotational position of the rotary table. The centrifugal measuring apparatus 1 is provided with a rotary table 2 that is driven by a motor, a retainer 3 to hold a biosensor accommodating a sample inside on the rotary table, an urged contact part 4 that establishes electrical connection with the electrode of the biosensor in such a manner as being elastically biased to abut against the electrode, a measuring part 8 that measures a signal from the electrode of the biosensor, and a connector part 7 that selectively establishes electrical connection between the urged contact part 4 and the measuring part 8.

Abstract: A method is provided for forming a thick and hard deposit having excellent thermal shock resistance on an engine valve made of a titanium material, particularly on its face and stem end, without allowing the formation of any brittle compound layer between the deposit and the valve material. An engine valve hardfaced on its face and stem end is also provided. A powder comprising a titanium material and 1 to 90% by weight of cobalt, or at least 25% by weight of a titanium material, 1 to 50% by weight of cobalt and 1 to 50% weight of a cobalt-based alloy is fused and deposited on an engine valve mad of a titanium material (e.g., on its face), and the deposited material is aged. The powder is prepared by mixing at least two powders, or from a molten alloy containing all of its constituents, to form a thick and hard deposit having excellent thermal shock and wear resistance on, e.g., the face of the engine valve and is, therefore, of high industrial utility.
