摘要： A battery-less multi-rotation encoder including detection coils with the Barkhausen effect includes a rotation detection mechanism and a signal processing circuit. The detection coils generate voltage pulses with different positive and negative signs, and transmit them to the signal processing circuit, and the signal processing circuit includes a controller and an adder. The controller can set states of the detection coils to be High or Low and to maintain them at High or Low, based on the positive and negative signs of the respective voltage pulses and no voltage pulse being generated therefrom. The controller is configured to store the states of the respective detection coils in a memory. The adder can update a number of rotations according to the changes in the states of the respective detection coils. The signal processing circuit can determine the rotational angle of a rotational shaft within about 1/4 rotation unit.

摘要： An agitation device, a melting apparatus, and a melting method for improving melting efficiency of molten metal without contaminating the same. The agitation device is provided with a traveling magnetic field generating unit which is disposed outside a charging tank for storing molten metal and generates, inside the charging tank, a magnetic field that travels downward along the rear sidewall of the charging tank. A flow of the molten metal that rotates longitudinally about an axis approximately parallel to the surface of the molten metal is produced in the molten metal. By charging aluminum cutting chips into the molten metal in which the flow is produced, the aluminum cutting chips move with a downward flow of the molten metal, and are immersed in the molten metal. As a result, melting of the aluminum cutting chips can be accelerated.

摘要： In a molding machine, a fixed platen which supports a fixed die is disposed on one end of a base plate. A movable platen which supports a movable die and a supporting mount which supports each one end portion of the four tie bars are mounted on slide units. The movable platen and the supporting mount are advanced so as to close the die, a tip portion of each tie bar is locked to the fixed platen by a lock mechanism, and a die clamping cylinder provided on the movable platen is actuated to generate a clamping force so as to execute molding. After that, the lock mechanism executes an unlocking operation so as to cause the movable platen and the supporting mount to retreat to a die open position. Furthermore, an attaching and detaching mechanism releases the die clamping cylinder so as to cause only the supporting mount to significantly retreat from the movable platen, and thus the four tie bars are completely evacuated from the fixed die and the movable die.
摘要翻译：在成形机中，支撑固定模的固定压板设置在基板的一端。支撑可移动模具的可动压板和支撑四个连接杆的每一个端部的支撑安装件安装在滑动单元上。可移动的压板和支撑安装件被推进以关闭模具，每个连杆的尖端部分通过锁定机构锁定到固定的压板上，并且设置在可动压板上的模具夹紧缸被致动以产生夹紧强制执行成型。此后，锁定机构执行解锁操作，以使可动压板和支撑底座退回模具打开位置。此外，安装和拆卸机构释放模具夹紧筒，从而仅使支撑安装件从可动压板显着退回，因此四个连接杆从固定模具和可动模具完全抽空。

摘要： A roof mounted light transmitting frame has a pair of longitudinal sash members. A light-transmitting sheet support sash member is mounted obliquely along the inner surface of each longitudinal sash member such that the distance between its front end and the lower edge of the longitudinal sash member is larger than the distance between its rear end and the lower edge of the longitudinal sash member. A lower horizontal sash member with a vertical support member is mounted between front ends of the light-transmitting sheet support sash members. An upper horizontal sash member is mounted between rear ends of the light-transmitting sheet support sash members. A light-transmitting sheet is mounted between the light-transmitting sheet support sash members, and the upper and lower horizontal sash members. A recess is longitudinally formed on the lower horizontal sash member to receive an upper horizontal sash member of the next frame.

摘要： A method determining a malfunction when a reception signal fluctuates at a receiver owing to malfunctions occurring on a leaky cable and its related devices. The method determines, among range bins correlating the reception signal with a distance from a feed end of a radio-wave radiation unit and a radio-wave reception unit, based on a correlation between a time-delay from a transmission time of a transmission signal until a reception time of the reception signal and a transmission path distance of the reception signal in the radio-wave radiation unit and the radio-wave reception unit, when, comparing the reception signal with the transmission signal with respect to the range bin corresponding to a far end, a level of amplitude reduction in the reception signal exceeds a predetermined ratio, that a malfunction is present in either the radio-wave radiation unit or radio-wave reception unit.
