An apparatus for supplying a granular material particularly a toner in a copying apparatus, comprises a material container which has a cylindrical interior wall with a discharge opening above the bottom of the wall on one side thereof. A rotatable scooping member in the form of a wire member having an elongated portion extending substantially parallel to and closely spaced from the interior wall along the longitudinal axis of the container rotates in the container and causes an agitation of the material so that it remains uniform and does not adhere to a wall of the container and in addition during its rotation it discharges a portion of the material outwardly through the discharge opening. The rotatable movement of the rotatable scooping member is effected through a driving transmission which includes a rotatable drive member having a leaf spring secured at its one end thereto and which projects radially outwardly. The free end of the leaf spring drives a rotatable member which is connected to the rotatable scoop to cause its rotation. During the movement of the spring the outer portion of the free end engages against a holding pin to cause the spring to flex until the rotation is such that the spring is suddenly released by the holding pin. This sudden release causes the spring to rapidly propel the scoop member ahead of it and to cause it to move rapidly and discharge the material picked up on its surface outwardly through the discharge opening. The holding pin is advantageously located so that the spring contacts the holding member just after it moves out of the material of the container toward the upper last quarter of its movement on one side of the container in a direction toward the opposite side having the discharge opening. In this manner the spring causes the scoop member to accelerate rapidly and to cause the material picked up thereby to become dislodged and move through the discharge opening.

A method and an apparatus for controlling the toner concentration of a dry developer, including a magnetic carrier and a non-magnetic toner, used in a magnetic brush developing system. The system includes an inherent magnetic means and an inheret circulation path through a portion of which a steady stream of the developer is established during its operation. A device such as a Hall element is set at a position near the steady stream portion of the developer and in the atmosphere for detecting the magnitude of a leakage magnetic flux from the portion which is emanated from the magnetic means, to determine the value of toner concentration of the developer in the system through analyzing. Thereupon, a supply of toner to the system is automatically controlled based on the determined value.

An apparatus for controlling the toner concentration of a dry developer, including a magnetic carrier and a non-magnetic toner, used in a magnetic brush developing system. In view of that the system includes an inherent magnetic means and an inherent circulation path through a portion of which a steady stream of the developer is established during its operation, a means such as a Hall element is set at a position near to the steady stream portion of the developer and in the atmosphere for detecting the magnitude of a leakage magnetic flux from the portion which is emanated from said magnetic means to determine the value of toner concentration of the developer in the system through analyzing. Thereupon, a supply of toner to the system is automatically controlled based on the determined value.

Either a single copy or a plurality of copies of an original document may be made. Making a single copy or the last copy of a plurality of copies comprises, during a first revolution of a photoconductive drum, electrostatically charging the drum, radiating a light image of the document onto the drum to form an electrostatic image, developing the electrostatic image using a magnetic brush to form a toner image, transferring the toner image to a copy sheet, electrostatically discharging the drum and uniformly radiating the drum with light to further discharge the same. During a second revolution of the drum the drum is cleaned with the same magnetic brush to remove residual toner, and again electrostatically discharged and uniformly radiated. During a third revolution of the drum the magnetic brush is again used for cleaning. For making all but the last of a plurality of copies, the drum is charged, imaged, transferred and electrostatically discharged during a first revolution thereof and cleaned with the magnetic bruch during a second revolution. Whether the process is used to make one or more copies, the same portion of the drum is always used. Subsequently, the drum rotation is indexed so that the next process will use a different portion of the drum.

A drive device for an electric vehicle in which, by improving a supporting structure of an input shaft of a speed reduction unit, the bearing stiffness of a hub bearing is improved, while the rotational accuracy and the durability of an input shaft of a speed reduction unit are improved and noise is suppressed. The drive device includes: a speed reduction unit including an input shaft driven by an electric motor; a hub unit rotationally driven by the speed reduction unit; and a housing. The input shaft of the speed reduction unit is supported by bearings provided at two locations in the axial direction. The bearings are both supported by the output member, and the PCD of the inboard-side hub bearing of the hub bearings disposed at the two locations in the axial direction of the hub unit is larger than the PCD of the outboard-side hub bearing.

An in wheel motor driving device which has a deceased axial dimension and includes aluminum alloy housings having a minimum wall thickness for reduced weight while retaining good assemblability. An in-wheel motor driving device includes: a motor section which has an output shaft; a wheel hub bearing section C; and a speed reducer section which connects the output shaft of the motor section and the wheel hub bearing section coaxially with each other. A housing outer circumferential portion of the motor section and a housing outer circumferential portion of the speed reducer section are integral with each other, being provided by one, outer circumferential member. An outboard-side end member is fixed to an outboard-side end of the outer circumferential member by means of bolts, and the wheel hub bearing section has its fixing ring fixed to the outboard-side end member.

A fuel cell system includes a source gas passage including a first desulfurizer that has a desulfurization performance relative to a source gas having a relatively higher dew point, and a second desulfurizer that has the desulfurization performance relative to a source gas having a relatively lower dew point and the source gas having the relatively higher dew point. The desulfurization performance of the second desulfurizer relative to the source gas having the relatively higher dew point is lower than the desulfurization performance of the second desulfurizer relative to the source gas having the relatively lower dew point. The first desulfurizer, the second desulfurizer, and a flowmeter are arranged at the source gas passage in the aforementioned order from an upstream side to a downstream side of the source gas passage in a flow direction of the source gas.

According to one embodiment, a data processing apparatus includes plural reconfigurable circuit layers, a first memory, a selecting unit, and a configuring unit. In each of the plural reconfigurable circuit layers, a processing circuit can be reconfigured. The first memory stores circuit information representing processing circuits that should be configured. The selecting unit selects, if it is unnecessary to use all the plural reconfigurable circuit layers in order to configure the processing circuits represented by the circuit information, a part of the reconfigurable circuit layers having high priority orders set in advance and otherwise selects all the plural reconfigurable circuit layers. The configuring unit configures, using the selected reconfigurable circuit layers, the processing circuits represented by the circuit information stored in the first memory.
