摘要： PURPOSE:To securely detect the damage of a rolling bearing by outputting the compared result of an acceleration vibration level when a rotation speed agrees with a reference rotation speed. CONSTITUTION:At the point of time when the rotation speed (c) of a rotary shaft 2 agrees with a reference rotation speed Rs, and only when a vibration level (b) resulting from the damage of a rolling bearing 3 becomes above the allowable level As in the reference rotation speed Rs, an AND circuit 12 is satisfied, sending out a warning signal (g) from a latch circuit 17. Accordingly, merely by setting only the allowable level As in an allowable-level setting device 11, a damage 19 more than allowable level that has developed on the rolling bearing 3 can be securely grasped.

摘要： PURPOSE:To enable the measurement of a phase difference without hunting by inputting two input pulse trains with an inhibiting circuit to a phase comparator, and annihilating one pulse when the phase difference exceeds a prescribed value. CONSTITUTION:Respective signal waves are inputted with zero cross comparators 5, 6 and inhibition circuits 12, 13 to a phase comparator 14. When an S input signal is first triggered, an output appears only at the SO output terminals, and when an R input terminal is first triggered, the opposite state takes place. The output of the comparator 14 closes switches 15, 16 respectively which input a DC voltage B to the phase noninverted terminal and phase inverted terminal of an operational amplifier 17. The output of the amplifier 17 is inputted with a low-pass filter 18 to a meter 21. On the other hand, when the phase difference exceeds +190 deg. or -190 deg., theta comparators 19, 20 output inhibition signals 19a, 20a to anhibilate one pulse and to make the output display -170 deg. or +170 deg.. The stable display is obtd. even if there is a

摘要： PURPOSE:To prevent automatic machining work from generating a failure while a tool from damage, by holding the tool so as to race for a main spindle, if excessive torque of predetermined value or more is applied to the cutting tool during its machining in a machine tool, and detecting abnormality of the tool. CONSTITUTION:A torque limiter 1, holding a tool 13, is mounted to a machine tool main spindle 20, performing cutting work. If excessive torque is applied to the tool 13, it rotates at a speed lower than that of the main spindle 20 or stops by racing the main spindle 20 and a torque limiter main unit 11 for a tool supporter 12. As a result, the tool 13 relaxes its excessive stress. This is because a ball 16 is dislocated from a recessed part 15 in the tool supporter 12 continuing to rotate and repeats to advance into the next recessed part 15, and a vibration is generated when this ball 16 advances into the recessed part 15. A device, converting this vibration into an electric signal by a vibration detector 2 and inputting the electric signal to a comparator 6 through an ampli fier 3, band pass filter 4 and an envelope detection circuit 5 to be compared with a preset value, detects abnormality of the tool 13.
摘要翻译：目的：为了防止自动加工工作在工具损坏时发生故障，通过握住工具以使其与主轴相对，如果在机床加工过程中对切削刀具施加预定值以上的过大扭矩工具，并检测工具的异常。构成：将保持工具13的扭矩限制器1安装在机床主轴20上，进行切削加工。如果对工具13施加过大的扭矩，则以比主轴20低的速度旋转，或者通过使主轴20和用于工具支撑件12的转矩限制器主单元11的摆动而停止。结果，工具 13放松它的过度压力。这是因为球16从工具支撑件12中的凹部15脱位继续旋转并重复进入下一个凹部15，并且当该球16进入凹部15时产生振动。一种装置通过振动检测器2将该振动转换为电信号，并通过放大器3，带通滤波器4和包络检测电路5将电信号输入到比较器6，以与预设值进行比较，检测异常工具13。

摘要： PURPOSE: To couple together safely, by automatically controlling a diesel locomotive (DL) by means of a signal of a position detector of the DL when the DL is coupled with a freight train.
CONSTITUTION: In the case of a DL 40 being coupled with a freight train 60-1, and when the DL and freight train come close to each other, a proximity switch 72 turns on, a signal is input to a wireless transmitter 74, and a low speed instruction is given to a wireless receiver 42. After the receiver 42 received the signal, the signal is input to an automatic train operating device 43, and they run at a low speed to couple together couplers 41 and 46. After coupling has been performed, a limit switch 47 turns on, and the automatic train operating device 43 stops the DL 40.
