摘要:
When a wire electrode is arranged along a traveling path by manual operation, a motor M1 for feeding the wire electrode to a workpiece is driven in response to a predetermined torque command from a control section with a switch SW1 on a side a. The wire electrode is connected, and a motor M2 for delivering the electrode from the wire is driven at a predetermined speed, whereby the electrode is run. Then, the switch SW1 is shifted to a side b and a switch SW2 to the side a, and the motor M1 is subjected to torque control such that a tension on the wire electrode detected by a tension detector is equal to a command tension. When a variation of the tension on the wire electrode is converged, the switches SW1 and SW2 are shifted to the side b, speed control of the motor M1 is performed so that detected tension is equal to the command tension, and electric discharge machining is started.

A machining fluid processing apparatus for an electric discharge machine capable of easily exchanging a filter for a new one. A filter is horizontally supported on a support table in a tray which is provided over a machining fluid tank. The contaminated machining fluid is supplied from the contaminated machining fluid tank to an attachment pipe in the filter by a pump. The contaminated machining fluid passes through the filter while machining dust is removed from the machining fluid. The clean machining fluid is then returned to the clean machining fluid tank. The exchanging of the filter is performed by removing a nut and a seal washer, detaching the used filter from the attachment pipe and attaching a new filter thereon. Since the filter is not submerged in the machining fluid and is drawn out horizontally along the support table, the filter exchange is made easy.

For maintenance and management of filters in a wire electric discharge machine, a sensor for detecting the filtration pressure is disposed between the filter and pump in the working fluid circulation channel. The sensor periodically senses the pressure and its output (transition of water pressure) is stored and sequentially displayed as a graph on a display device to allow monitoring of filter clogging by checking such sensor output at the time of commencing the processing.

The printer (1) includes a control unit (20) including a function reproducing multiple tones by outputting energization data that is dot control data in multiple cycles in line units to a head unit (10) including a plurality of dot generating elements disposed in a line. The control unit (20) includes: a thermal head control circuit (60) supplying the energization data of each cycle and a latch signal for the energization data of each cycle to the head unit (10); and a mask circuit (70) operable when the energization data of the current cycle is the same as the energization data of the previous cycle, to erase the current energization data and the signal for latching to be supplied to the head unit (10).
摘要:
A power storage device has a NaS battery for storing electric power, a Hall current detector for measuring charge/discharge current value I of the NaS battery, a bidirectional converter for converting electric power between a direct current and an alternating current bidirectionally, and a controller for controlling the power storage device. The controller integrates the charge/discharge current value I of the NaS battery and calculates the calculated value of the discharge capacity in the NaS battery. The controller calculates estimated error Er(t2) of the calculated value of the discharge capacity, specifies NaS battery 1004 that requires the correction of the calculated value of the discharge capacity, charges/discharges the NaS battery to a depth of discharge at which the calculated value of the discharge capacity is corrected, and corrects the calculated value of the discharge capacity in the charged/discharged NaS battery.

摘要:
Provided are a control apparatus for a secondary battery and a control method for a secondary battery, which suppress decreases in released power and absorbed power. When a power storage device is requested to release power, a limit for power supply to a power consuming body is set relatively higher, and when the power storage device is requested to absorb power, the limit for power supply to the power consuming body is set relatively lower. When the power storage device is requested to release power, a command value PD for released power is calculated by adding supplied power PS to a requested value PE for released power. When the power storage device is requested to absorb power, a command value PC for charged power is calculated by subtracting the supplied power PS from a requested value PA for absorbed power.
