摘要： A drive state control apparatus is applied to a vehicle which has not only a transfer including a multi-disc clutch mechanism but also a changeover mechanism interposed in an axle and which can be switched between 2WD and 4WD. When a 2WD-to-4WD changeover condition is satisfied, the multi-disc clutch is immediately switched from a “decoupled state” to a “coupled state.” Meanwhile, a connecting operation of the changeover mechanism is started upon establishment of a state in which left and right rear wheels have no acceleration slippage, and a state in which rotational speeds of first and second axles on opposite sides of the changeover mechanism are approximately equal to each other. In addition, in the case where the left and right rear wheels have acceleration slippage after the 2WD-to-4WD changeover condition has been satisfied, an E/G output reduction control is executed. Thus, the connecting operation can be performed smoothly.

摘要： Waveguide-type optical phase modulator regions of a linear accelerator-type column electrode structure MZ optical modulator are arranged on a semiconductor optical waveguide. A transmission line of an integrated circuit receives a clock signal through a buffer circuit disposed on an input side. Clock terminators are connected between an end of the transmission line and clock terminator power supply electrodes (VCa, VCb). Individual driving circuits receive the clock signal from different positions of the transmission line. An i (1≦i≦m, i is an integer)-th individual driving circuit counted from the input side outputs a signal obtained by amplifying a digital input signal in synchronization with the clock signal to an i-th waveguide-type optical phase modulator region.

摘要： A spark plug includes a center electrode extending along an axial line, a ground electrode, and a noble metal tip. A center axis of the noble metal tip is displaced from a center axis of the ground electrode toward a base-end side in the axial line. The ground electrode includes an outer layer and an inner layer, and a distal end of the inner layer is closer to the axial line than a base end of the ground electrode. An overlap area between the inner layer and the noble metal tip occupies a ratio of 25% or more in a projective plane defined by projecting, along the center axis, a plane of the ground electrode viewed from a distal-end face on a cross section of the ground electrode in which a maximum cross-sectional area of the inner layer is achieved, among cross sections orthogonal to the center axis.

摘要： An isolation portion (P) of an insulator (10) of a spark plug (100) electrically insulatively isolates a front end portion (22) of a center electrode (20) and a holding portion (56) of a metallic shell (50) from each other and has an intermediate portion (P2) which extends while its outside diameter varies, thereby ensuring an insulation distance between the two portions. The ratio (S/V) of the surface area (S) of the outer surface (14) of the isolation portion (P) to the volume (V) of the isolation portion (P) satisfies the relation 1.26 mm−1≦S/V, whereby the insulation distance between the front end portion (22) and the holding portion (56) is sufficiently ensured while existing dimensional conditions are held unchanged. Through satisfaction of the relation S/V≦1.40 mm−1, an increase in temperature of the center electrode (20) that accompanies an increase in the amount of heat received from a combustion chamber owing to an increase in the surface area (S) of the outer surface (14) is restrained, thereby maintaining a required heat value.

摘要： An on-demand-type drive state control apparatus for a vehicle is provided. In the case where acceleration slippage occurs at drive wheels (rear wheels) of a vehicle when a drive system is in a two-wheel drive state, the drive system is switched from the two-wheel drive state to a four-wheel drive state. That is, the maximum transmittable torque of a multi-disc clutch mechanism increases from “0” to a predetermined value. In the four-wheel drive state, the maximum transmittable torque decreases stepwise from the present value by a predetermined value every time the vehicle travels over a predetermined distance in a state in which none of the wheels cause acceleration slippages. That is the clutch drive current supplied to the multi-disc clutch mechanism decreases gradually (stepwise or in a plurality of steps), and the drive torque distributed to the front wheels (rear wheels) decreases (increases) gradually.
摘要翻译：提供了一种用于车辆的按需驱动状态控制装置。当驱动系统处于两轮驱动状态时，在车辆的驱动轮（后轮）处发生加速滑移的情况下，驱动系统从两轮驱动状态切换到四轮驱动状态。也就是说，多盘离合器机构的最大可传递扭矩从“0”增加到预定值。在四轮驱动状态下，在没有车轮引起加速滑动的状态下，每当车辆行驶超过预定距离时，最大可传递扭矩从当前值逐步减小预定值。也就是说，提供给多片离合器机构的离合器驱动电流逐渐（逐步地或以多个步骤）减小，并且分配给前轮（后轮）的驱动扭矩逐渐减小（增加）。
