  • Patent number: 10478914
    Abstract: For butt-welding, which includes bringing joining end surfaces of a cup member and a shaft member into abutment against each other and radiating a high energy intensity beam from a radially outer side, the shaft member has a recess on a radially inner side of the joining end surface to obtain a welded portion having a closed hollow cavity on a radially inner side after butt-welding. The joining end surface (protruding surface) of the cup member protrudes toward a radially inner side with respect to an inner diameter of the joining end surface of the shaft member. With this, a welded portion of an outer joint member of a constant velocity universal joint, which is manufactured by joining the cup member and the shaft member, can be improved in strength and quality.

  • Patent number: 9671419
    Abstract: A liquid collection device is configured to determine a difference between a liquid level after suction operation determined by calculation based on the liquid level detected at the time of previous probe lowering operation and a liquid level that is actually detected at the time of current probe lowering operation, to detect presence of foam if the difference is greater than a first threshold set as a maximum value of an allowable error set in advance in the device and is equal to or smaller than a second threshold that is set greater than the first threshold, and moreover, to display a warning to an operator when presence of foam is detected.

  • Patent number: 7823535
    Abstract: Methods and apparatuses for dispensing samples or reagents onto a target object are provided. A dispensing position designating section (62) designates the dispensing position on the target object (50), such as a membrane, based on an image of the target object (50) displayed on a monitoring section (60). A dispensing control section (64) positions the target object and the dispensing device relative to each other so that the designated dispensing position on the target object is placed beneath the dispensing device (10) and controls the dispensing operation of the dispensing device (10). A dispensing position information creating section (68) creates dispensing position information about the dispensing position on the target object (50) which is designated by the dispensing position designating section (62) and to which the dispensing operation has been performed and outputs it to the outside.
