    Abstract: A hydraulic piston pump in which a cylinder port (4b) can be communicated with a discharge port (9) after a system pressure (Po) and a chamber pressure (Pi) in a cylinder bore are in an equilibrium state. A through-hole (16) opened in that surface of a valve plate (7) on which a cylinder block (3) slides is communicated with one end surface (21a) side of a balance valve (20), and the system pressure (Po) on the discharge port (9) side is supplied to the other end surface (21b) of the balance valve. A balance piston (21) is built-in in the balance valve, and the balance piston (21) slides by a pressure difference between the chamber pressure (Pi) in the cylinder bore (4) and the system pressure (Po). Before a cylinder port (4b) is communicated with an oil guiding groove (15), the chamber pressure (Pi) and the system pressure (Po) can be brought into an equilibrium state by actuation of the balance piston (21).

    Abstract: A charging circuit generates a charging current from an ac supply which is supplied to a secondary battery in a battery package through first terminals. A second terminal receives a temperature detection signal from a thermistor on the secondary battery. A value of the temperature detection signal is sampled every predetermined interval. A memory stores the sampled value. A difference between the sampled value and the value from the memory is obtained, as well as the temperature decrease value between the sampled value and the value stored, when it applies. An error signal is generated when the difference is higher than a predetermined value and the operator is alarmed and informed of the error. The difference may be obtained between the sampled value and the value one-cycle-previously-sampled value from the memory, between the sampled value and a minimum of the sampled values, or between the sampled value and a charging start value of the sampled value. The thermistor is supplied with a supply voltage through a switch and an error condition caused by leakage of the electrolyte from the battery is detected when the voltage at the second terminal is higher than the predetermined value, the charging current generation circuit is controlled to stop generating the charging current.

    Abstract: A drive motor connected to a drill bit serves to actuate the drill bit. An electric current is allowed to flow through the drive motor to activate the drive motor. A mechanism serves to feed the drill bit with respect to a workpiece. The current flowing through the drive motor is sensed. A device stores a value of the current which is sensed when the drill bit is out of engagement with the workpiece. A determination is made as to whether or not a drilling process is completed in accordance with a value of the present sensed current and the stored value of the sensed current.

    Abstract: A speed controller for a DC motor includes a semiconductor switching device connected in series with it in a DC power circuit. The switching circuit is turned on and off with a duty ratio variable as a function of motor load. A time constant circuit including a capacitor is connected in parallel with the switching device to develop a voltage which is compared with a reference variable between high and low levels in response to the exceedance of the varaible reference. The switching device is turned on when the voltage developed by the capacitor is higher than the lower reference voltage to energize the motor, and is turned off when the capacitor voltage is lower than the higher reference voltage to de-energize the motor. The on-duty period of the motor is variable as a function of a motor-load representative voltage developed in the switching device during its turn-on period and the off-duty period is variable as a function of a counter-electromotive force generated in the motor as inversely proportional to motor load.
