A fuel cell having a structure capable of certainly supplying a gas by making effective use of a limited space while ensuring the portability of the fuel cell is provided. The fuel cell includes two generators, a fuel supply portion, and two planar current collectors. Each of the generators has a proton conductor film, and a planar hydrogen side electrode and a planar oxygen side electrode disposed with the proton conductor film held therebetween. The fuel supply portion is adapted to supply a fuel to the hydrogen side electrodes of the generators. The planar current collectors, which are disposed in close-contact with the oxygen side electrodes of the generators, have gas transmission portions such as opening portions allowing the oxygen side electrodes to be opened to atmosphere. Since the oxygen side electrodes are opened to atmosphere, oxygen can be supplied to the generators without lowering a partial pressure of oxygen in air.

When a plurality of sets of a document with an image formed on one side thereof is read, the plurality of sets (341, 342, and 343) of the document is stacked and arranged in a document tray (33), in a state with front and back sides of each set mutually reversed. By sequentially reading images of the plurality of sets of the document arranged in the document tray (33) and detecting the front and back sides of the document, switching of each set of the document is detected, in response to detection of switching of the front and back sides of the document.

The present invention is an image forming apparatus having no two-sided printing mechanism in which, by setting a front side printed paper sheet in a manual paper feed section, the paper sheet is taken from the manual paper feed section and a back side printing is executed. At this moment, when a paper detecting switch 24 detects presence of a paper sheet on a manual paper feed tray 23 at the end of the front side printing, a message meaning to remove the paper sheet and thereafter to set the front side printed paper sheet is given. Whether the paper sheet is removed or not is detected according to a change-over of the paper detecting switch 24, and the back side printing is executed after the paper sheet is removed and the front side printed paper sheet is set. As a result, erroneous back side printing on an improper paper sheet can be prevented and a two-sided printing can be correctly executed.

A molded component for the beam path of a radar apparatus with a low radio transmission loss and improved hardness and abrasion resistance is provided. The molded component for the beam path of a radar apparatus comprises a base body 21 composed of a cyclic polyolefin resin layer, and a bright decoration layer 23 disposed on the surface of the base body. Preferably, by disposing a modified layer 22 treated by plasma ion etching and/or highly concentrated ozone water especially on the surface of the cyclic polyolefin resin, wettability on the surface is improved, thereby substantially improving the adhesion to the bright decoration layer.

A non-aqueous electrolyte comprises an aluminum halide and a quaternary ammonium halide dissolved in a non-aqueous solvent. A non-aqueous electrolytic cell is also described, which comprises an anode made od Al or its alloy, an cathode and the non-aqueous electrolyte provided between the anode and the cathode. The non-aqueous electrolyte is suitable for electrodeposition of aluminum from the electrolyte. Because aluminum is reversibly electrodeposited from and dissolved in the electrolyte, the electrolyte is usable for making secondary cells having good charge and discharge characteristics and a high energy density.

A method and system for requesting an interrupt from a host system to service an adapter connected to the host system and a data interface. Data packets, including one or more data cells, are transferred between the data interface and the host system. The host system includes a host memory that includes a plurality of memory slots to store data packets transferred between the data interface and the host system. It is determined when a transfer of data has resulted in an occurrence of an interrupt event. An interrupt event occurs when the transfer of data includes a transfer of a data cell between the data interface and the host system and the data cell is defined to be an end of a data packet. In response to the occurrence of an interrupt event, it is determined whether to generate an interrupt request to the host system. This step of determining includes determining whether a predetermined interval of time has elapsed since the host system last processed an interrupt request or determining whether a predetermined number of interrupt events have occurred since the host system last processed an interrupt request. If the predetermined interval of time has elapsed or the predetermined number of events has occurred, respectively, the interrupt request from the adapter to the host system is generated.

An ink jet printer of the present invention includes a recovering device for repeating, at the time of recovery from defective ink ejection, the suction of ink a plurality of times while varying a suction pressure acting on the ink. This successfully reduces the amount of bubbles and reduces the number of times of suction to thereby obviate the wasteful consumption of ink at the time of recovery. A printing method practicable with the ink jet printer and a storage medium storing the printing method are also disclosed.

An ink jet printer comprises a cap having a shape that defines a cavity around the printhead, a cap body formed with a lip region and a beam extending across the cavity, and a basin structure formed with a vent for providing an exit passage from the cavity through a vent port. The cap body and the basin structure cooporate to define a capillary space to create an effective seal between the cavity and the vent associated therewith.

A switch valve contacts flexible tubes that connect caps for printheads to a pump. The switch valve includes a tube support. The support is formed with grooves receiving intermediate portions of the flexible tubes, which tubes are curved along rounded corner sidewalls that project toward an entrance of the support. A rotary member controls pivotal motion of a lever. The lever pivots in one direction to squeeze one of the tubes against the associated one of the corner sidewalls, and it pivots in the opposite direction to squeeze the other one of the tubes.
