摘要:
A metal gasket material plate has improved adhesion of a rubber layer to a metal plate by use of an adhesive layer, so as to prevent the rubber layer from happening delamination of the metal plate and to provide a chromium-free material plate in consideration of adverse effects on the environment and a human body. In a laminated metal gasket material plate provided with a rubber layer on a metal plate by use of an adhesive layer, the metal gasket material plate includes silane-based chemical conversion coating being formed between a surface of the metal plate and the adhesive layer by applying a silane coupling agent containing any of an epoxy group, a mercapto group, and an amino group as a functional group. Here, the adhesive layer is made of a phenol resin-based adhesive, and the rubber layer is made of an NBR-based rubber mixture.

Disclosed is a metal gasket which is capable of securing a sealing properties by strongly pressing a portion of a bead thereof, which faces a portion where a pressuring surface of one joining surface of one of an intake manifold and an EGR plate does not exist, to the other joining surface thereof. A metal gasket which is clamped between the two joining surfaces and has at least one hole for fluid, includes a bead for sealing the two joining surfaces, the bead surrounding the at least one hole for fluid, each of which allows openings for fluid to be communicated with each other, the openings being provided in the respective joining surfaces. The metal gasket further includes a convex portion, the tip of which abuts one of the joining surfaces, is provided in the vicinity of a portion of the beads abutting the other joining surface.

A process of catalytic partial oxidation of a hydrocarbon fuel with an oxidant to produce partially-oxidized reaction products including hydrogen, with simultaneous in-situ coke removal. The process involves feeding a hydrocarbon fuel and an oxidant to a reactor in a fuel-rich feed ratio; reacting the fuel and oxidant for a fuel-rich cycle-time so as to produce a partially-oxidized reaction product; varying the fuel feed, or the oxidant feed, or both feeds to produce a fuel-lean feed to the reactor; maintaining the fuel-lean feed for a fuel-lean cycle-time sufficient to reduce coke deposits while maintaining a substantially constant yield of partially-oxidized reaction product; and alternating between the fuel-rich and fuel-lean operating cycles.

In one embodiment, an optical touch device is disclosed. The device includes a housing having an opening through which a screen is exposed, light-emitting elements provided along a first side of the opening and configured to emit infrared light, and a drive unit configured to sequentially select and drive the light-emitting elements. The device further includes a detection control unit configured to output a timing signal synchronized with the timing of the driving operation of the drive unit and to detect a position of a blocking object on the screen. Further, the device includes light-receiving sensors, provided along a second side of the opening, opposite the first side of the opening, configured to be selected by the timing signal to output to the detection control unit a result of reception of the infrared light, the light-receiving sensors including different kinds of light-receiving sensors differing in a light-receiving characteristic.

An apparatus for fuel reforming is provided that utilizes pulsed injectors for a fuel flow controller and an air flow controller, and the injectors are integrated with an atomizing mixer thereby producing a fuel-air mixture having an O/C Ratio which, in turn, is passed to a Catalytic Partial Oxidation reactor. Use of this apparatus permits beneficial long term operation of this Catalytic Partial Oxidation reactor.

Provided is a fuel reforming device, which can produce and supply a reformed gas in quick response to a demand for the reformed gas and which is so inexpensive as can be suitably mounted on a vehicle. The fuel reforming device feeds a material to a reforming catalyst and produces the reformed gas under a pressure higher than the atmospheric pressure. The fuel reforming device comprises a material supply means for supplying the material to the reforming catalyst, a reforming means having the reforming catalyst, for reforming the material supplied from the material supply means, to produce the reformed gas, and a run control means for controlling the run of the fuel reforming device. The run control means includes a stop mode, in which the drive of the material supply means is stopped to stop the production of the reformed gas, a reform mode, in which the material supply means is driven to produce the reformed gas, and a standby mode, in which the material supply means is driven and in which the temperature of the reforming catalyst is held within a predetermined range while producing the reformed gas as little as possible, so that the standby mode can shift instantly to the reform mode.

An exhaust cleaning method and exhaust cleaning apparatus for an internal combustion engine (1) in which a fuel is fed and burned under periodical rich/lean combustion conditions. In a fuel reformer (18) disposed independently of an exhaust channel (11) in the engine (1), the fuel for the internal combustion engine (1) is reformed to produce a reformed gas containing carbon monoxide. The reformed gas is supplied to the exhaust to be introduced into an exhaust converter (17) having, disposed therein, a catalyst which adsorbs and reduces nitrogen oxides. The nitrogen oxides contained in the exhaust gas are adsorbed and reduced. Thus, the nitrogen oxides contained in the exhaust are removed at a high efficiency.

A method for reforming a diesel fuel with high efficiency under a same condition as that of gasoline or the like to continuously produce hydrogen with high selectivity and high yield is provided. By allowing three catalysts having different functions from one another to be in a composite state and, then, controlling a reforming reaction of the diesel fuel, the diesel fuel is reformed with high efficiency under a same condition as that of gasoline or the like and, accordingly, hydrogen can continuously be produced with high efficiency and high yield.

An abrasive wheel made of an abrasive which is chemically reactive with a ceramic workpiece and a binder mixed with the abrasive is held against the ceramic workpiece at a temperature ranging from 40.degree. C. to 300.degree. C. preferably 100.degree. C. to 180.degree. C., under at least an atmospheric pressure in a moistening atmosphere within a pressure vessel. The abrasive wheel is rotated in abrading contact with the ceramic workpiece. A surface layer of the ceramic workpiece which is held against the abrasive wheel is mechanically abraded and also subjected to a tribochemical reaction with the abrasive wheel, so that the surface layer of the ceramic workpiece can smoothly and neatly be removed from the ceramic workpiece. The ceramic workpiece thus ground is finished highly accurately and efficiently.
