    • A printed circuit board includes a first electric conductive layer formed on an insulating base plate to form signal patterns and a ground pattern. An insulation layer covering the signal patterns and a second electric conductive layer connected to the ground pattern are sequentially formed on the plate. A large area ground land is formed in the vicinity of a ground terminal of a digital IC by the first electric conductive layer to be connected to the ground terminal, which is directly surface-mounted to the second electric conductive layer so that a ground impedance of the ground terminal can be reduced. A large area power source land connected to a power source terminal of the digital IC is formed in the vicinity of the power source terminal by the first electric conductive layer, which sandwiches the insulation layer in cooperation with the second electrostatic conductive layer so that an electrostatic capacitance larger than a line-to-line distribution capacitance formed by the signal patterns can be formed between the power source land and the second electric conductive layer.

    • A bicycle type training machine includes a crank arm secured to a rotation shaft, pedals being attached to the both free ends of the crank arm. A rotation shaft of a generator is coupled to the rotation shaft of the crank arm. Data of load amount to be loaded to the rotation shaft of the crank arm is outputted by a microcomputer. The load value data is then compared with a count value of a counter to which a pulse train is applied from a reference oscillator, and a pulse signal having the high level and the low level in accordance with a result of the comparison is outputted from a comparator. A duty ratio of the outputted pulse signal is decided by the periods of the high level and the low level and changed in accordance with the load value data. A switching transistor electrically connected in parallel to an armature of the generator is turned-on or -off in response to the high level or the low level of the pulse signal. Braking force of the generator is changed in accordance with the duty ratio of the switching transistor. Therefore, the load that is decided by the load value data from the microcomputer is loaded to the rotation shaft of the crank arm and thus the legs of the user.
    • 自行车式训练机包括固定在旋转轴上的曲柄臂,踏板连接到曲柄臂的两个自由端。 发电机的旋转轴联接到曲柄臂的旋转轴。 由微型计算机输出装载到曲柄臂的旋转轴的负载量的数据。 然后将负载值数据与从参考振荡器施加脉冲串的计数器的计数值进行比较,并且根据比较结果输出具有高电平和低电平的脉冲信号 比较器。 输出脉冲信号的占空比由高电平和低电平的周期决定,并根据负载值数据而变化。 与发生器的电枢并联电连接的开关晶体管响应于脉冲信号的高电平或低电平而导通或断开。 发电机的制动力根据开关晶体管的占空比而改变。 因此,由微型计算机的负载值数据决定的负载被加载到曲柄臂的旋转轴,从而被加载到使用者的腿部。
