摘要： A plunger barrel has a sliding bore in which a plunger is slid, a sleeve acceptor in the shape of a hole for a control sleeve which is formed in an intermediate portion of the sliding bore and a window portion which is opened in a wall defining the sleeve acceptor. The plunger barrel is manufactured by the steps of preparing a blank having one end portion and another end portion, forming a first bore axially from the one end portion of the blank, so as to provide a diameter equal to that of the sleeve acceptor, to an intermediate portion of the blank, drawing the one end portion of the blank so that a portion in which the sleeve acceptor is formed remains, forming a second sliding bore in the blank so as to penetrate from the one end portion to the other end portion of the blank, and forming a window portion in a wall of the sleeve acceptor.

摘要： An improved emitter coupled logic circuit suitable for high speed logic operation independent of capacitive load. With previous circuits as the load to be driven become heavier, the capacitive load required a longer time for discharge and the output signal was dulled, resulting in adverse effect on the logic operation when the output changed to a low level from a high level. A pulse has also been previously applied to a pull-down transistor connected between the output and a power source through a capacitor from an inverted phase output to actively discharge the capacitive load. However, when the capacitor is connected to the output it hinders the switching speed of a current switch. In the present invention, a transistor is provided an input circuit and a pulse is applied to a pull-down transistor from the transistor. As a result, an extra capacitive element is not connected to the output end, but a pulse is applied to the pull-down transistor. Accordingly, even if the capacitive load becomes heavier, the speed of the circuit is not harmed.

摘要翻译： 一种改进的发射极耦合逻辑电路，适用于独立于电容负载的高速逻辑运算。 随着驱动负载变得越来越重，电容负载需要较长的放电时间，输出信号变钝，当输出从高电平变为低电平时，对逻辑运算产生不利影响。 先前已经将脉冲施加到通过来自反相输出的电容器连接在输出和电源之间的下拉晶体管，以主动放电容性负载。 然而，当电容器连接到输出时，它阻碍了电流开关的开关速度。 在本发明中，晶体管被提供有输入电路，并且脉冲从晶体管施加到下拉晶体管。 结果，额外的电容元件不连接到输出端，但是脉冲被施加到下拉晶体管。 因此，即使容性负载变重，电路的速度也不会受到损害。

摘要： A muting device of an upright piano which includes butt, a wippen, a capstan button and a muting mechanism (15). This butt rotates with a hammer which strikes a string of the upright piano. In addition, a jack is provided to come in contact with a lower surface of the butt, and rotates the butt in response to displacement of the key. The jack is supported by the wippen such that it can freely rotate. The capstan button is provided at a back edge portion of the key to transmit displacement of the key to the wippen. The muting mechanism is designed to reduce a string-striking stroke by rotating the hammer. Further, there is provided a key-displacement-transmission-rate changing mechanism. When reducing the string-striking stroke by the muting mechanism, this mechanism raises a displacement transmission point, at which displacement of the key is transmitted to the wippen, toward a rotation center of the key from the capstan button. Preferably, this mechanism includes another capstan button which is placed on an upper surface of the key at a position between the capstan button and rotation center of the key.
