摘要： An electric drill is prevented from operating when failure of electric power during a drilling operation is restored to normal and when breaking of a coil in an electromagnet occurs. When failure of electric power is restored to normal in a state, in which a switch (50) is switched so as to energize an electromagnet and an electric drill, a photocoupler (38) operates to actuate a thyristor (31) and inhibit an on-operation of a transistor (35). As a result, a motor (16) of the electril drill will not operate before the electromagnet does. Also, abnormality of a coil (27) is judged on the basis of that abnormality of electric potential across a resistor (28), which is detected by a potential difference judging circuit (30). When abnormality is detected, the thyristor (31) is actuated and on-operation of the transistor (35) is inhibited. As a result, the electric drill will not operate when its operation is not permitted by the electromagnet.

摘要： A vibration switch (10) is constituted by assembling discoid electrodes (11 and 12) having aligned projecting parts (16) on their internal surfaces together at a prescribed interval and putting a spherical body (13) in the space (21) between the electrodes (11 and 12) so that the electrodes (11 and 12) can be electrically connected to each other when the switch (10) vibrates or rolls. A portable motor-driven device provided with such a switch (10) is constituted in such a manner that the switch (10) is attached to a frame (1). When a portable power tool (4) is apt to roll or tilt sideways due to an excessive load while the tool (4) is used to cut a material, the switch (10) is turned on and the power supply to the controller (6) of the tool (4) is interrupted to immediately stop a tool rotating motor (4M) or feeding motor (5M), even though the tool (4) is used at any angle.

摘要： When a start switch (SW3) is depressed, a one-shot multivibrator circuit (15) is actuated to output one pulse. When the pulse enters a self-holding circuit (16), the self-holding circuit (16) is self-held to output an H-level signal until reset. As a result, a transistor (17) is turned on to actuate a relay (R1) for lowering a ram. When the ram reaches the lower limit position, a lower limit switch (LS4) is opened, so that a signal from a one-shot multivibrator circuit (18) causes a self holding circuit (21) to self-hold an H-level signal. The signal is delayed by a delay circuit (22) to turn a transistor (23) on. Therefore, a relay (R2) for raising the ram is actuated. Restarting will not be effected due to the operation of the one-shot multivibrator circuit (15) even when the start switch is kept depressed. Also, the service life of a valve changeover mechanism can be extended owing to the operation of the delay circuit (22). Further, erroneous operations can be prevented by operations of a delay circuit (19) and an AND circuit (24) even when the lower limit switch (LS4) chatters.
摘要翻译：当启动开关（SW3）被按下时，单稳态多谐振荡器电路（15）被致动以输出一个脉冲。当脉冲进入自保持电路（16）时，自保持电路（16）自我保持以输出H电平信号直到复位。结果，晶体管（17）导通以致动用于降低压头的继电器（R1）。当柱塞达到下限位置时，下限开关（LS4）打开，使得来自单稳多谐振荡器电路（18）的信号使自保持电路（21）自我保持H电平信号。信号由延迟电路（22）延迟以使晶体管（23）导通。因此，用于升高冲头的继电器（R2）被致动。即使启动开关保持按压，由于单稳态多谐振荡器电路（15）的操作也不会重新启动。此外，由于延迟电路（22）的操作，可以延长阀切换机构的使用寿命。此外，即使下限开关（LS4）颤动，也可以通过延迟电路（19）和AND电路（24）的操作来防止错误的操作。

摘要： This invention provides a machining method capable of molding a tapering through hole at a stroke by one pressing operation. The boring of a work is done by using a smaller-diameter punching portion (1a) formed at a front end of a punch (1) fixed to a press. A hole (11) thus made by press molding has an opened lower end with a broken-out section. A tapering surface is formed on the inner side of the hole (11) by plastic machining by a tapering machining portion (1b), which has a diameter somewhat larger than that of the hole and a tapering surface (T), with this hole (11) used as a guide. Due to this plastic machining operation, a burn portion (3a) is going to be formed at an outer circumferential edge portion of the hole (11) but the actual formation of such a portion (3a) is prevented by a holding portion (1c) formed on the punch (1). If these steps are carried out by a single pressing operation, a through hole having a plurality of tapering sectional shapes can be molded more simply.
