Abstract: Motor control devices and methods are described herein. In one embodiment, such a device includes a fluid ejection head configured to eject a fluid onto a sheet that is on a downstream side from a transport driving roller along a supply direction of the sheet. The device also includes a first motor that provides a driving force for rotating a roll on which the sheet is wound, and a second motor that provides a driving force for driving the transport driving roller. The transport driving roller is on a downstream side from the roll along the supply direction of the sheet. The device also includes a motor control unit that simultaneously drives the first and second motors, and the motor control unit is configured to control an interpolation output that is given to the first motor while subjected to a change in a driving speed of the second motor.

Abstract: Image forming apparatuses include: a casing; an image forming unit removable from the casing in a first direction; and plural developer cartridges. The cartridges may be attached and detached with respect to the image forming unit in a second direction that is inclined toward the first direction. Other image forming apparatuses include: a casing; an exposure device; a plurality of cartridges configured to be attached and detached with respect to the casing in a first direction; and a recording medium transport system for transporting recording media adjacent the photosensitive members in a second direction. The first direction may be inclined with respect to the second direction, and at least a portion of optical paths of the light emitted from the exposure device may extend parallel with the first direction. Aspects also relate to image forming units, e.g., for use in image forming apparatuses as described above.

Abstract: An operating apparatus for game machine includes a depressing member. A main body of the depressing member is provided with three engaging protrusions and two depressing protrusions that downwardly protrude. For example, the two depressing protrusions are provided between the three engaging protrusions. In response to a beating operation, the right side of the depressing member is depressed, and an engaging portion of the engaging protrusion at the left side is engaged with a rear surface of an upper surface panel. Accordingly, the depressing member depressed at the right side without being upwardly actuated, and a rubber switch depressed by the depressing protrusion is brought into contact with a board. At this time, a contact provided on the board and a contact provided on the rubber switch are brought into contact with each other, and an operation signal according to the beating operation is output to the game machine.

Abstract: The substrate storage pod includes a pod case for housing a substrate, and an opening, a lid member which closes and seals the opening, a buffer space which is defined in the lid member, an air-supply port for supplying a replacement gas into the buffer space; and multiple holes which are arranged so as to establish communication between the buffer space and an inner plate of the lid member in a state of being fit-inserted to the opening of the pod case, for sending out the replacement gas into the hollow inner space, the replacement gas having been supplied into the buffer space, the inner plate facing the hollow inner space of the pod case. With this, pressure variation of the replacement gas in supply pipes is blocked, and hence replacement-gas flow in a stable laminar state free from disturbance can be obtained.

Abstract: A developing cartridge that maintains a pressing condition to press a developer carrier against the image carrier is described. The developing cartridge may include a coil spring that presses the developer carrier against the image carrier. The coil spring may include a handle that transmits a pressing force to the coil spring via the contacting member. By doing so, every time the developing cartridge is replaced, a new coil spring and handle can be provided for the color laser printer with the developing cartridge attached. Therefore, a constant pressure by the coil spring can be continuously maintained. Thus, a preferable pressure condition of the developer carrier against the image carrier can be continuously maintained.

The developing unit is detachable from and attachable to the casing through the opening. The developing unit is movable selectively to one of a proximity position, a separated position, and a pivoted position where the developing agent bearing member is pivotally moved about a portion of the developing agent bearing member at the second side from the separated position in a direction away from the photosensitive drum. The developing unit is detachable from and attachable to the casing along the axial direction in a state where the developing unit is at the pivoted position.

Abstract: A method of producing ultra-fine metal particles of the present invention includes: blowing metal powders of raw materials into reducing flame formed by a burner 3 in a furnace 5, wherein the metal powders are melted in the flame and allowed to be in an evaporated state, to thereby obtain the spherical ultra-fine metal particles. In the present invention, the atmosphere in the furnace 5 is preferably prepared such that the CO/CO2 ratio is within a range from 0.15 to 1.2. Also, a spiral flow-forming gas is preferably blown into the furnace 5, and the oxygen ratio of the burner 3 is preferably within a range from 0.4 to 0.8. As raw materials, a metal oxide and/or a metal hydroxide which contain the same metal as the metal powders may be used together with the metal powders.

Abstract: The substrate storage pod includes an engagement portion in an outer side surface of a lid of the pod, and an insertion slot through which the engagement portion can be accessed from an external space; the insertion slot is formed in a flange portion arranged around the periphery of an opening in the pod and into which the lid can be fitted, and a latch mechanism supported so as to be slidable in a direction parallel to a flange side wall in a pod main body-surface of the flange portion. An engaging portion of the latch mechanism reaches the engagement portion via the insertion slot. The engagement portion is switched between an engaged state and a non-engaged state in response to movement of the latch mechanism.

Abstract: In an image forming apparatus, a drum supporting member integrally supports a plurality of photosensitive drums. A moving member detachably supports the drum support member. The moving member moves between a mounted position, in which the moving member is mounted in a main body of the image forming apparatus, and a pulled-out position, in which the moving member is pulled out of the main body of the image forming apparatus. A belt is disposed above the moving member and is capable of contacting with the plurality of photosensitive drums when the moving member is disposed in the mounted position. The drum supporting member is detached upward from the moving member when the moving member is in the pulled-out position. The drum supporting member rotatably supports each of the photosensitive drums.
