An acceleration sensor includes: a semiconductor substrate including a support layer and a semiconductor layer, which are stacked in a first direction; a movable electrode and a fixed electrode; and a trench. The movable electrode separately faces the fixed electrode by sandwiching the trench along with a second direction. The trench has a detection distance in the second direction. The movable electrode is movable along with the first direction when acceleration is applied. The movable electrode has a bottom apart from the support layer. The width of the movable electrode along with the second direction is smaller than the width of the fixed electrode. The thickness of the movable electrode along with the first direction is smaller than the thickness of the fixed electrode.

The invention relates to a method and a system for regulation of the rotational speed (52) of a rotor on a wind energy unit with a generator and a rotor blade. The first set parameter is a pitch angle (Pitch) of the rotor blade and the second set parameter is the torque of the generator. The system comprises a pitch angle control or regulation device (32), a torque control or regulation device (33), a first device for determination of a first rotational speed set value (28) (first rotational speed set value determination device (29)) and a second device (26) for determination of a second rotational speed set value (29) (second rotational speed set value determination device (26)). The first rotational speed set value (28) may be supplied to the pitch angle control or regulation device (32) and the second rotational speed set value (29) may be supplied to the torque control or regulation device (33), wherein the first and second rotational speed set value (28, 2)) may be different from each other.

An air conditioning device includes a casing that provides multiple air passages, a blower fan that suctions an air from the multiple air passages and blows out the air in the casing, a suction side partitioning member that is disposed on a suction side of the blower fan in the casing and separates air flows from the multiple air passages from each other, and a blowing side partitioning member that is disposed on a blowing side of the blower fan in the casing and separates the air flows from the multiple air passages from each other. The suction side partitioning member and the blowing side partitioning member are disposed so that a relative position of the blowing side partitioning member to the suction side partitioning member is deviated in a rotation direction of the blower fan.

The invention discloses an anti-tail out automatic control system of hot continuous rolling thin strip steel, mainly comprising a signal detection device, a programmable logic controller (PLC) and a control actuating mechanism; the roll forces on both sides detected by a roll force sensor are compared in the PLC to obtain a deviation signal, after being processed by a signal filtering processing unit, the deviation signal subtracts the roll force deviation value maintained by a current rack when a previous rack throws steel, and then an initiating threshold value and action direction are judged through a judging unit for regulating the initiating threshold value and a judging unit for regulating the action direction, when the deviation value is up to the threshold value, the action direction can be judged out according to the positive and negative of the difference value, in addition, under the condition of satisfying linkage, a roll seam horizontal regulation signal is output throughan UP or DOWN terminal within the range of horizontal regulation amplitude limiting value of the roll seam between the linkage and a protection unit to control the actuating mechanism to control the horizontalness of the roll seam. In the invention, the adaptation of a rolling mill system at the tail end of strip steel is improved, thereby reducing operating trouble of strip steel, improving the stability of strip steel rolling process, and solving the problem that artificial manual regulation is not in time.
