Abstract: A mixing device of an exhaust aftertreatment device includes: an elbow pipe attached to an outlet pipe of a filter device; a straight pipe connected to a downstream side of the elbow pipe to extend in a direction intersecting an axial line of the outlet pipe; and an injector attached to the elbow pipe, the injector injecting a reductant aqueous solution into inside the elbow pipe toward the straight pipe. The elbow pipe includes: an inlet connected with the outlet pipe; an outlet connected with the straight pipe; a direction-changing section provided between the inlet and the outlet; and an injector attachment provided outside the direction-changing section and attached with the injector. The injector attachment is offset toward the outlet. The direction-changing section includes a first bulging portion provided by bulging outward a portion thereof opposite to the injector attachment.

Abstract: The present invention relates-to-a-vacuum pump and a method of starting a vacuum pump. The vacuum pump includes a pump rotor (1) rotatably disposed in a casing (2), and a pump-rotor controller (15) for controlling rotation of the pump rotor (1) in a forward direction or a reverse direction in accordance with a predetermined pattern at the time of starting the vacuum pump.

Abstract: The present invention is to provide a magnetic bearing controller capable of reliably controlling the position of a floating member at a target position, even when the length of the cable connecting the magnetic bearing and the controller is changed. The magnetic bearing controller comprises: an electromagnet for supporting a floating member in a floating state; sensors (Z1, Z2) for sensing the floating position of the floating member; and a controller for supplying sensor signals and an exciting currents via cables to the sensors and electromagnets, respectively, in order to support the floating member at a predetermined floating position based on signals received from the sensors, wherein the controller comprises.

Abstract: A magnetic suspending device which can detect the temperature of a controlled object and assure a safe operation thereof without any need for any special construction or work to the device and any special maintenance is disclosed.

Abstract: A DC motor apparatus which can be started with a power supply having a small current capacity and which provides a large driving force. The DC motor apparatus comprises a permanent magnet in a rotor of the DC motor, a plurality of coils provided at a stator of the DC motor, a distributor for controlling the switching of current paths to the coils and a position detector for detecting a rotational position of the rotor of the motor to output switching signal to the distributor. A pulsating unit is further provided for pulsating currents supplied to the coils whereby a current flowing from the distributor to any one of the coils can be pulsated when the DC motor is activated, resulting in easy starting the DC motor.

Abstract: A displacement sensing circuit for sensing a displacement of a measured object without any contact with the measured object. A detecting coil is disposed relative to the measured object to be capable of changing its inductance in response to a displacement of the measured object from a predetermined position. An output signal from the detecting coil is passed through a band-pass filter. The filter has a frequency band width which is equal to at least twice the upper limit of a response frequency of the sensing circuit, thereby outputting a signal less influenced by a noise. An output from the band-pass filter is detected to provide a signal corresponding to the displacement of the measured object.
