A monitoring apparatus is to be applied to an assisted circulation apparatus, the assisted circulation apparatus being connected to a living body, transferring blood removed from the living body to a membrane lung by a blood transfer pump, and gas-exchanging and oxygenating the blood in the membrane lung in parallel with a native lung, and the monitoring apparatus includes a calculation unit that calculates a blood gas-exchanging state index indicating a gas-exchanging state of blood by the assisted circulation apparatus.

Monitoring apparatus and assisted circulation apparatus

The information storing medium has a substrate, a storing element, provided on the substrate, for storing information, a protecting portion, covering the storing element, for protecting the storing element, an electrical contact point that is provided beside the protecting portion on a side of the substrate, on which the storing element is provided, and is electrically connected to the storing element, and a sliding region that is provided on the electrical contact point. In the information storing medium, when the storing medium is mounted on the apparatus main body, the electrical contact point contacts a main body electrical contact point provided on the apparatus main body. Also, when the electrical contact point and the main body electrical contact point contact each other, the main body electrical contact point slides on the electrical contact point in the sliding region.

Information storing medium, unit, process cartridge, developing cartridge, and electrophotographic image forming apparatus

An image forming apparatus usable with a process cartridge comprising an image bearing member and a process device actable on the image bearing member includes guide device, contactable with the process cartridge, for guiding in the loading direction the process cartridge to be loaded into a main assembly of the apparatus; a positioning device for positioning the process cartridge, which is in the disengaged state from the guide device, into the loading location; and a pressing device for pressing the process device onto the positioning device.

Process cartridge and image forming apparatus usable with this process

A module connecting mechanism of an electrophotographic apparatus includes an engine module having an electrophotographic process section, a supplying module for supplying a transfer sheet to the electrophotographic process section, and a conductive module connecting mechanism for connecting an installation section of the supplying module with an installation section of the engine module electrically. A common plane extending substantially in parallel with the direction of connecting the supplying module with the engine module is formed over the supplying module and the engine module in order to connect the supplying module and the engine module at the installation portions electrically, wherein the engine module is superposed on the supplying module.

Electrophotographic apparatus having a module fixing member

An image forming apparatus, to which a process cartridge is detachably mountable, for forming an image on a recording material. The image forming apparatus includes a first guiding device for guiding the process cartridge toward a predetermined mounting position when the process cartridge is mounted to the image forming apparatus. The first guiding device is disposed upstream of the predetermined mounting position with respect to a mounting movement direction of the process cartridge. A second guiding device is provided for guiding the process cartridge toward the predetermined mounting position when the process cartridge is mounted to the image forming apparatus The second guiding device is disposed (i) closer to the predetermined position than the first guiding device, and (ii) downstream of the first guiding device with respect to the mounting movement direction. Also provided is a feeding device for feeding the recording material.

A process cartridge is detachably mountable to an image forming apparatus for forming an image on a recording material. The process cartridge includes an image bearing member, a process device for acting on the image bearing member, which includes a developing device for developing an image on the image bearing member, a frame, and a projection disposed on the upper surface of the frame and extending toward the developing device, the projection having (i) an upward inclined surface, (ii) a flat surface continuing from the upper inclined surface, and (iii) a downward inclined surface that is inclined toward the developing device.

An image recording apparatus includes a sheet material accommodating device for accommodating sheet materials, a sheet material feeding device for feeding the sheet materials from the sheet material accommodating device, an image recording device for recording images on the sheet materials fed by the feeding device, sheet material refeeding device for refeeding to the image recording device through a refeeding passage the sheet material on which an image has been formed by the image recording device, a sheet material reversing device for reversing the sheet material and conveying it to the image recording device, the sheet material reversing device being disposed downstream of the refeeding passage with respect to a movement direction of the sheet material substantially within a projection area of the sheet material accommodating device.

Image recording apparatus with refeeding path

The present invention provides an image forming apparatus having a sheet re-supplying path. The re-supplying path for supplying a sheet on which the image has been formed by the image forming apparatus back to the image forming apparatus. A rotatable feeding member is disposed in the sheet re-supplying path for pinching and feeding a leading end portion of a previous sheet, a second rotatable feeding member is disposed at an upstream side of the rotatable feeding member and is in the sheet re-supplying path for permitting the entrance of a next sheet in a condition that a trailing portion of the previous sheet is situated in the second rotatable feeding member, and a controller for permitting the second rotatable feeding member to feed the next sheet after the trailing end of the previous sheet fed by the rotatable feeding member has passed through the second rotatable feeding member.

Image forming apparatus having a sheet re-supply path

A sheet obliquely conveying apparatus is provided with a pair of sheet conveying rollers including a forwardly and reversely rotatable drive roller and a follower roller rotatable in contact with the drive roller, and bearing structure for rotatably supporting the shaft of the follower roller. The dimension of the bearing portion of the bearing structure which supports one end of the shaft of the follower roller is greater generally along the direction of conveyance of a sheet material than the dimension of the bearing portion of the bearing structure which supports the other end of the shaft of the follower roller. The apparatus is further provided with a resilient device generally parallel to the direction of conveyance of the sheet material for pressing the shaft of the follower roller.

Apparatus for conveying a sheet obliquely

An image forming apparatus usable with a process cartridge having an improved positioning mechanism between the process cartridge and an optical system of the main assembly of the image forming apparatus. The process cartridge and the optical system are freely movable supported in the main assembly, and positioning portions of the process cartridge and the optical system are abutted to a positioning member fixed to the main assembly of the image forming apparatus.

Process cartridge and image forming apparatus using same

A dynamic pressure fluid bearing, and particularly a dynamic pressure fluid bearing for effectively ensuring a minute gap between the shaft of the dynamic pressure fluid bearing and a bearing. More particularly, fluid intervenes between the shaft and the bearing and these two rotate relative to each other in a non-contact state, and a part or the whole of the bearing is formed of resin and the resin is endowed with electrical conductivity.

Dynamic pressure fluid bearing

The present invention provides an apparatus for rotationally driving a member to be rotated about a rotating shaft, said apparatus including a central fixed shaft, a hollow shaft rotatably mounted on the central shaft through bearings, a member adapted to be rotated with the hollow shaft, a rotor held by the hollow shaft, and a stator fixedly supported opposed to the rotor.
