    • A front-wheel speed is calculated as a wheel speed of driving wheels, a rear-wheel speed is calculated as a wheel speed of driven wheels, a rear-wheel acceleration is calculated as a wheel acceleration of the driven wheels, a front-wheel-speed difference value is calculated as a driving-wheel-speed difference value, a rear-wheel-speed difference value is calculated as a driven-wheel-speed difference value, a rear-wheel-acceleration difference value is calculated as a driven-wheel-acceleration difference value, and a front-wheel ground load is calculated as a ground load acting on the driving wheels. Based on these calculated values, a gradient of a tire-characteristic curve indicating an amount of change in road-surface friction coefficient with respect to an amount of change in slip rate is calculated, and the calculated gradient of the tire-characteristic curve is compared with preset threshold values, whereby a road-surface friction coefficient as a road-surface condition can be determined.
    • 前轮速度被计算为驱动轮的车轮速度,后轮速度被计算为从动轮的车轮速度,后轮加速度被计算为从动轮的车轮加速度,前轮 计算速度差值作为驱动轮速度差值,将后轮速度差值计算为从动轮速度差值,将后轮加速度差值作为从动轮速度差值计算, 车轮加速度差值和前轮地面载荷被计算为作用在驱动轮上的地面载荷。 基于这些计算值,计算表示路面摩擦系数相对于滑移率变化量的变化量的轮胎特性曲线的坡度,并且比较计算出的轮胎特性曲线的坡度 具有预设阈值,由此可以确定作为路面状况的路面摩擦系数。

    • A drill according to an embodiment of the present invention includes a body part and a cutting part with a cylinder-like shape. The cutting part includes two cutting edges located separately from each other at a front end portion of the cutting part, two flutes which are continuous with each of the two cutting edges and extend spirally toward a rear end portion of the cutting part, and a clearance which extends spirally from a side of the front end portion to a side of the rear end portion, and is recessed inward in reference to a periphery of the cutting part in a sectional view. The cutting part includes a first joining flute including at least one of the two flutes and the clearance being joined together. The first joining flute includes a bottom surface being outwardly protruding curve-like line in a sectional view. A method of manufacturing a machined product using the drill is also provided.

    • This invention provides a fluid control device capable of making compact a fluid control device in which a valve and a limit switch are combined. A valve 6 includes a piston 26 as a moving member which includes a protruding portion protruding from an opening of a casing 21, and which linearly moves according to opening and closing of the valve 6 so as to abut against a limit switch 7. The limit switch 7 is made to face the piston 26 and is attached via a limit switch positioning unit 8 so as to be adjustable about its position. The limit switch positioning unit 8 includes a first bolt 42 fixed to a body 2, a second bolt 43 fixed to the limit switch 7, and a connection screw 44 which connects both the bolts 42, 43. The first bolt 42 and the second bolt 43 have different pitches from each other.
