Abstract: There is provided a load detector including a beam-type load cell which is supported on a support base in a cantilever manner, and a platform connected to the beam-type load cell. The platform includes a main body on which a subject is to be placed and a slope having a first end, which is connected to the main body, the slope being configured to guide the subject to the main body. The slope is configured to swing between a first position in which a second end of the slope is in contact with a placement surface on which the load detector is placed and a second position in which the second end is separated from the placement surface. The platform further includes a lever connected to the first end of the slope and positioned above the main body.

Abstract: There is provided a load detector including: first and second beam-type load cells which are supported on first and second support bases, respectively, in a cantilever manner; a placement part on which a rolling body is to be placed, and which includes first and second connection parts connected to the first and second beam-type load cells, respectively, and a pair of walls, the placement part being disposed between the first and second beam-type load cells; and a restriction member which is detachably attached to at least one of the pair of walls, and which is configured to restrict a posture of the rolling body on the placement part. The first connection part is connected to the first beam-type load cell on a side of the free end and the second connection part is connected to the second beam-type load cell on a side of the free end.

Abstract: The load detector includes: first and second beam type load cells which are supported on first and second support bases in a cantilever manner to have free ends; and a mounting part on which an object is to be placed, which includes first and second connection parts connected to the first and second beam type load cells, and which is disposed between the first and second beam type load cells. The free ends of the first and second beam type load cells face opposite directions to each other in an extending direction of the first beam type load cell. The first and second connection parts of the mounting part are respectively connected to the first and second beam type load cells on a side of the free ends of the first and second beam type load cells.

Abstract: It is provided a long life spindle motor that is excellent in startup characteristic in low-temperature environments such as 0° C., and that startup problems due to the evaporation or deterioration of lubricating oil can be avoided in high-temperature environments. The spindle motor includes a fluid dynamic bearing filled with a lubricating oil, containing a methyl pentanediol diester obtained by esterifying 3-methyl-1,5-pentanediol with n-decanoic acid and n-undecanoic acid at a molar ratio ranging from 90:10 to 20:80, and having a water content of not more than 1000 ppm.

Abstract: There is provided a fluid dynamic pressure bearing apparatus including a shaft, a bearing sleeve rotatably supporting the shaft, and a lubricating oil filled between the shaft and the bearing sleeve, wherein at least one of the shaft and the bearing sleeve is formed of a copper alloy containing 0.8 wt % to 5 wt % of lead, and a base oil of the lubricating is a member selected from the group consisting of monoester, dibasic acid diester, diol ester and mixtures thereof, and the lubricating oil contains 0.1 wt % to 1 wt % of condensed phosphate ester. The fluid dynamic pressure bearing apparatus is capable of suppressing the hydrolysis of the lubricating oil, and the wear of the shaft and the bearing sleeve.
