Abstract: Provided is a grinding method capable of preventing variation in the outer diameter of a processed object 1 at the completion of grinding regardless of change in the amount of elastic deformation of the processed object 1 based on the change in the cutting ability of a grindstone 4. The outer diameter D of the processed object 1 during grinding is measured by gauge heads 5 in process. Plural target values Di that differ from each other are set for the outer diameter D of the processed object 1, and first threshold values are set for the rate of change of the outer diameter D of the processed object for each of these target values Di. Spark out is started when the outer diameter D of the processed object 1 becomes equal to a target value Di and the absolute value of the rate of change v is greater than a first threshold value that corresponds to the target value Di.

Abstract: A gateway device includes a base processor which converts a signal input from an IP network to a signal which can be handled by the gateway device, and a home appliance control processor having a controller which converts the signal which can be handled by the gateway device to a control signal in compliance with the communications protocol of a home appliance to be controlled. The controller stores, on a table, information about the communications protocol, driver, controllable setting condition and status of respective appliances to be controlled in association with each other. The controller also includes a conversion functional block which converts information supplied to the control information of the communications protocol of the respective appliances to be controlled on the basis of the stored information.

Abstract: In a constant-velocity-joint-assembly positioning system, a first boot positioning apparatus includes a clamping mechanism for clamping a central drive shaft of a constant velocity joint assembly, a right boot positioning mechanism for positioning a right boot of the joint assembly and a left boot positioning mechanism for positioning a left boot of the joint assembly. The boot positioning apparatus variably sets distances, from the left boot positioning mechanism, of the clamping mechanism and right boot positioning mechanism. A transfer-pallet-position adjusting apparatus includes an adjusting mechanism by which positions of first and second joint-assembly gripping mechanisms are adjusted in accordance with differences between current and target positions of the gripping mechanisms.
