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.
