Abstract: A device according to the present disclosure is configured to, when it is determined that the road on which a vehicle travels is an uphill road and the speed of the vehicle is controlled such that the vehicle follows a preceding vehicle, in a case where the preceding vehicle is no longer detected, inhibit the acceleration of the vehicle or decelerate the vehicle until it is determined that the road on which the vehicle travels is no longer the uphill road, or alternatively, until a certain period of time elapses.

Abstract: A cutting apparatus includes a chuck table configured to hold the workpiece, and a cutting unit fitted with a cutting blade including an annular base and a cutting edge that includes abrasive grains and a binder configured to fix the abrasive grains, and is formed along an outer circumferential edge of the base. The cutting unit includes a spindle, a blade mount fitted to a distal end portion of the spindle, and a fixing nut configured to fix the cutting blade to the blade mount, and the blade mount or the fixing nut is provided with a corrosion layer formed of a material having a higher ionization tendency than a material constituting the binder.

Abstract: An annular grindstone includes a grindstone portion including a binding material, and abrasive grains which are dispersed into the binding material to be fixed, in which the binding material contains a nickel-iron alloy. Preferably, a contained ratio of iron in the nickel-iron alloy is in a range of 5 wt % or more to less than 60 wt %. More preferably, a contained ratio of iron in the nickel-iron alloy is in a range of 20 wt % or more to 50 wt % or less. Preferably, the annular grindstone includes the grindstone portion only. In addition, the annular grindstone further includes an annular base including a grip portion, in which the grindstone portion is exposed at an outer peripheral edge of the annular base.

Abstract: An annular grindstone includes a grindstone section that includes a binder and abrasive grains dispersed and fixed in the binder, in which the binder includes a tin-nickel alloy. Preferably, a content of tin in the tin-nickel alloy is equal to or more than 57 wt % and less than 75 wt %. In addition, preferably, the annular grindstone consists of the grindstone section. Alternatively, the annular grindstone further includes an annular base having a grip section, and the grindstone section is exposed to an outer peripheral edge of the annular base.
