    • An output signal of a vibration sensor mounted on an internal combustion engine is compared with a background noise reference signal to produce a knock signal which can accurately represent the intensity of knocking. The background noise level signal is produced by averaging a component of the vibration sensor output signal which represents the vibration of the engine other than knock-induced vibration. In order to produce a feedback signal for inhibiting the knock induced component of the sensor output signal, a first comparator compares the sensor output signal with a first reference signal having a sufficiently low level. Knock signal is produced by a second comparator which receives a second reference signal, which is proportional to the first reference signal but having sufficiently higher level, thereby enabling a precise determination of knock intensity.
    • 安装在内燃机上的振动传感器的输出信号与背景噪声参考信号进行比较,以产生可以准确地表示爆震强度的爆震信号。 背景噪声电平信号是通过对表示发生器的振动以外的振动传感器输出信号的分量进行平均而产生的,而不是敲击引起的振动。 为了产生用于抑制传感器输出信号的敲击感应分量的反馈信号,第一比较器将传感器输出信号与具有足够低电平的第一参考信号进行比较。 敲击信号由第二比较器产生,第二比较器接收与第一参考信号成比例但具有足够高的电平的第二参考信号,由此能够精确地确定爆震强度。

    • An elevator control system for controlling a plurality of elevator cars servicing a plurality of floors of a building by allotting a hall call originated from one of the floors to a suitable one of the elevator cars so that the hall call can be serviced by the selected elevator car. In the elevator control system, a scan signal generator is provided to generate a scan signal which is used to sequentially scan the floors in successive scan slots for detecting hall calls and elevator car service positions and converting the detected information into pulse signals. The elevator control system comprises counters for counting up the service loads of the individual elevator cars in the successive scan slots after the detection of the elevator car service positions, so that, when a hall call is detected in one of the scan slots, an elevator car providing a minimum service load at the specific scan slot can be selected, and the detected hall call can be allotted to the selected elevator car. The elevator control system of such construction may be divided into a plurality of blocks classified by their control functions. These blocks are electrically isolated from one another by isolating means which permits transmission of signals among them. In a modification, the scan signal generator may be provided in each of the blocks.
    • 一种电梯控制系统,用于通过从其中一个楼层分配起始于其中一层的门厅呼叫来控制对建筑物的多个楼层进行维修的多个电梯轿厢,以适应一个电梯轿厢,使得门厅呼叫能够被所选择的电梯 汽车。 在电梯控制系统中,提供扫描信号发生器以产生扫描信号,该扫描信号用于在用于检测门厅呼叫和电梯轿厢服务位置的连续扫描时隙中依次扫描楼层,并将检测到的信息转换为脉冲信号。 电梯控制系统包括用于在检测到电梯轿厢服务位置之后在连续扫描时隙中对单个电梯轿厢的服务负载进行计数的计数器,使得当在一个扫描槽中检测到门厅呼叫时,电梯 可以选择在特定扫描时隙提供最小服务负载的汽车,并且可以将检测到的门厅呼叫分配给所选择的电梯轿厢。 这种结构的电梯控制系统可以分为多个通过其控制功能分类的块。 这些块通过允许它们之间的信号传输的隔离装置彼此电隔离。 在修改中,可以在每个块中提供扫描信号发生器。
