Abstract: To reliably prevent re-lifting of a rear wheel immediately after landing of the rear wheel. When it is determined that output of a detection signal corresponding to detection of lifting of a rear wheel has ended (S102), brake pressure—and specifically a pressure increase gradient of a wheel cylinder pressure of a front wheel—is reduced, and the pressure increase gradient that has been reduced is maintained until it is determined that vehicle body deceleration has fallen below a predetermined value K1 (S108, S110), whereby re-lifting of the rear wheel caused by an increase in brake pressure at a high pressure increase gradient after landing of the rear wheel can be reliably prevented.

Abstract: A two-wheeled motor vehicle brake control method and system which immediately reduces the brake pressure of the front wheel when rear wheel lifting is detected regardless of whether or not the front wheel is skidding. The reduction in brake pressure can be an amount which corresponds to the amount of lifting. The reduction in brake pressure can be performed in a stepwise manner until lifting is no longer being detected; it can be performed in a stepwise manner with a limit on the number of steps; or it can be performed in a stepwise manner until a total pressure reduction amount is achieved.

Abstract: It is an object of the invention to provide a brake control device that can accurately detect a rear wheel lift off state and that is not easily affected by a road surface state, a wear condition of a tire, a slipping state of a front wheel and an operation of a driver etc. In a brake control device that controls a front wheel anti-lock brake system of a front wheel brake of a two-wheel vehicle, it is determined whether the front wheel brake is being braked at equal to or more than a predetermined braking force. If it is determined that braking is being performed at equal to or more than the predetermined braking force, it is determined whether a rear wheel is lifting off in accordance with a slipping state of the rear wheel, and if it is determined that the rear wheel is lifting off, the front wheel anti-lock brake system is activated.

Abstract: To enable, with respect to a vehicle where lifting of the vehicle body easily occurs to a relatively large extent even in a relatively early stage when rear wheel lifting is detected, more rapid and reliable securement of the safety of the vehicle body with respect to that rear wheel lifting. When lifting of a rear wheel is detected, in contrast to what has conventionally been the case, the brake pressure of a front wheel is immediately reduced (S102) regardless of whether or not there is occurrence of skidding of the front wheel, so lifting of the entire vehicle body is rapidly and reliably controlled and prevented particularly in a vehicle whose entire vehicle body is easily lifted even by slight rear wheel lifting.

Abstract: A method of leaching zinc from a zinc concentrate comprising leaching a zinc concentrate in an aqueous solution containing free sulfuric acid and ferric ions, whereby elemental sulfur is deposited on the zinc concentrate, and grinding the zinc concentrate under atmospheric pressure in the aqueous solution to provide particles of the zinc concentrate having surfaces, wherein the elemental sulfur and other by-products which form on the surfaces of the particles of the zinc concentrate are stripped by the grinding.

Abstract: An apparatus for leaching zinc concentrates which comprises: a pressure vessel for charging therein a solution containing at least free sulfuric acid and iron ions, a stirrer which is disposed in the pressure vessel, an oxygen gas supply pipe that extends into the pressure vessel from the outside of the pressure vessel, the oxygen gas supply pipe having an oxygen gas inlet port which opens below the stirrer, and a discharge pipe through which an iron-containing, acidic solution or a slurry that results from the reaction of said solution containing at least free sulfuric acid and iron ions is discharged to the outside of the pressure vessel, the discharge pipe having a drain port which is open in a lower part of said pressure vessel.

Abstract: In one method, a zinc concentrate is leached as elemental sulfur and other by-products are stripped from the surfaces of the particles in the concentrate by means of a grinding machine such as a ball mill. The ferric ion consumed by leaching is regenerated for recycled use by introducing oxygen into the post-leaching solution flowing through feed pipes. This method can shorten the leach time by a substantial degree.
