Abstract: A blade member, mountable onto an electrophotographic image forming apparatus, such as copier, printer, facsimile, word processor, and the like, for removing residual matter from an electrophotographic photosensitive member, includes an elastic blade one side surface of which is flat in a longitudinal direction thereof and the other side surface of which has a vertical portion perpendicular to an end surface of the elastic blade, and an inclined portion inclined with respect to the vertical portion, the inclined portion having a larger thickness than the vertical portion, and a support member for supporting the elastic blade. A thickness (f) of a portion of the elastic blade, which is engaged by the support member at a side of the one side surface, is greater than a thickness (g) of a portion of the elastic blade which is engaged by the support member at a side of the other side surface.

Abstract: The present invention provides a cleaning apparatus for removing adhered matter from a member to be cleaned. The apparatus includes a cleaning device abutted against the member to be cleaned and adapted to remove the adhered matter from the member to be cleaned. In addition, the apparatus includes a receiving unit for receiving the adhered matter removed from the member to be cleaned, a guide member for directing the removed matter to the receiving unit, an adhesive member for adhering the guide member to the receiving unit, and an end seal member provided on the guide member at an end portion. The adhesive member protrudes from a longitudinal end edge of the guide member.

Abstract: A process cartridge mountable to an image forming apparatus includes a frame, an image bearing member, a toner carrying member for directing toner to the image bearing member, and a magnet disposed within the toner carrying member. A common positioning member, separate from the frame, contacts each of the image bearing member and the magnet to mutually position the image bearing member and the magnet.

Abstract: A mouthpiece unit of a diving respirator wherein a device for opening and closing an aperture of a mouthpiece side of a mouthpiece unit body is provided, and a part of a respirable gas for operating the device is applied to the device through a valve which is opened by the jaw of a diver and a pilot valve which is opened by an inspiration of the diver. A water exhaust port communicating with a gas room of a mouthpiece side formed in the mouthpiece unit body and a valve for closing the water exhaust port are provided on the mouthpiece unit body, the valve being opened when the gas room is increased in pressure.

Abstract: A process cartridge mountable within an image forming apparatus, includes an image bearing member, process means acting on the image bearing member, a frame, and a first guide surface provided on the frame and adapted to guide a recording medium toward the image bearing member, and a second guide surface recessed more than the first guide surface and having width smaller than that of the first guide surface. With the above construction, it is possible to provide a process cartridge and an image forming apparatus within which such a process cartridge can be mounted, which can be made small-sized and light-weighted and which are easy to use.

Abstract: A throttle valve of a diving respirator, wherein an orifice valve is inserted slidably in a hole of a cylindrical valve body, an orifice is formed in said valve body so as to communicate a gas outlet and a gas inlet formed on the valve body, and a gas passage is formed between the gas outlet and the gas inlet, which is opened only when a gas pressure in the gas inlet is elevated to a predetermined valve so that the orifice valve is moved relative to the valve body.

Abstract: A method for testing smoke sensor is to set a predetermined level for alarm generation on the basis of information on a first output of a main light receiving element for a stray light caused by an emitted light from a main light emitting element, a second output of an auxiliary light receiving element for the emitted light directly received from the main light emitting element and a composite output of the first and second output whereby tests for confirming normal operation and the like of the smoke detector can be executed with high precision.

Abstract: An image display device includes thin film transistors and pixel electrodes arranged in matrix form on a substrate. A semiconductor layer forming a channel region of the thin film transistor also serves as the pixel electrode, thereby making the structure of the device simple and facilitating fabrication thereof.

Abstract: The power generation system includes a reformer and two fuel cell stacks. The reformer and the fuel cell stacks are provided in series. Fuel gas produced by the reformer is introduced to a first anode of the first fuel cell stack. Gases discharged from the first anode are directly introduced to a second anode of the second fuel cell stack. Air is introduced to a first cathode of the first fuel cell stack. Gases discharged from the first cathode are cooled by a cooling device and then introduced to a second cathode of the second fuel cell stack. Gases discharged from the second anode and gases discharged from the second cathode are introduced to a heating chamber of the reformer. Gases discharged from the heating chamber are introduced to a steam generator to produce steam used for reformation and then recirculated to the first cathode.

Abstract: An electric power producing system using a molten carbonate type fuel cell, comprises a fuel cell whose anode chamber is provided with hydrogen gas and whose cathode chamber is provided with air and carbon dioxide and a reformer including a reforming chamber for reforming fuel gas into anode gas and a combustion chamber for maintaining reforming chamber temperature. In the reformer, fuel gas and steam are fed into the reforming chamber, gases discharged from the anode chamber are introduced into the combustion chamber and non-reacted gases in the anode exhaust gas are burned with air, and heat produced upon the combustion is used to heat the reforming chamber.

Abstract: A power generation system uses fuel cells stacked via separators. Cooling plates are provided in the fuel cell stack. Passages are formed in each cooling plate for allowing raw-material-gas-for-reformation (which also serves as stack-cooling-gas) to flow therethrough and the passages are filled with reforming catalyst. An external reformer which includes a combustion section and a reforming section is provided outside of the fuel cell stack. A stack-cooling-gas-line is connected to the passages of the cooling plates for introducing the raw-material-gas-for-the-reformation (the stack-cooling-gas) into the passages. A line for gas-for-processing is connected to the reforming section of the external reformer for feeding raw-material-gas-for-processing to the reforming section. An anode gas feed line is provided for feeding to the anode the reformed gas which has been reformed through the passages of the cooling plates and the reformed gas which has been reformed by the reforming section of the external reformer.
