Abstract: Provided are a negative electrode that is for use in a non-aqueous electrolyte secondary battery, includes a porous metal body as a current collector, contains a skeleton-forming agent highly infiltrated in the current collector so that it is less likely to suffer from structural degradation and provides improved cycle durability; and a non-aqueous electrolyte secondary battery including such a negative electrode. The negative electrode for use in a non-aqueous electrolyte secondary battery includes a current collector including a porous metal body; a first negative electrode material disposed in pores of the porous metal body and including a conductive aid, a binder, and a negative electrode active material including a silicon-based material; and a second negative electrode material disposed in pores of the porous metal body and including a skeleton-forming agent including a silicate having a siloxane bond.

Abstract: A lubricating oil sealing apparatus for use of a turbocharger having a compressor wheel for supplying a supercharged air through an intake passage, a turbine wheel driven by a force of an exhaust gas, and a driving shaft connecting the compressor wheel with the turbine wheel. The apparatus is located between the compressor wheel and turbine wheel, and has a labyrinth structure therein in order to prevent the lubricating oil from being suctioned into the intake passage.

Abstract: An elastic supporting and sealing member, for mutually supporting a first body and a second body, and for sealing the gap between the first body and the second body, includes a first portion and a second portion of wire net and a piece of thermal foaming material, between the first and the second wire net portion, which expands and foams when it is heated up. A method of making such a member includes the steps of flattening a tubular shaped piece of wire net, and of introducing a strip shaped piece of such thermal foaming material between the two sides of the flattened tube of wire net, so that the longitudinal directions of the strip shaped piece of thermal foaming material and of the flattened wire net tube substantially coincide.

Abstract: A helically-shaped intake port comprising a helical portion formed around an intake valve, and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A rotary valve is arranged in the bypass passage and has an arm connected to a vacuum operated diaphragm apparatus. The rotary valve has a stop which is engageable with the arm. The arm is normally in engagement with the stop due to the spring force of a coil spring for retaining the rotary valve precisely at the maximum open position.

Abstract: A helically-shaped intake port comprising a helical portion formed around an intake valve, and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A rotary valve is arranged in the bypass passage and actuated by a vacuum operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of an engine is increased beyond a predetermined value. The diaphragm apparatus comprises a diaphragm and a control rod interconnecting the diaphragm to the rotary valve. A first stop and a second stop, which are engageable with the housing of the diaphragm apparatus, are fixed onto the control rod for retaining the rotary valve at the full open position and at the completely closed position, respectively.

Abstract: A helically-shaped intake port comprising a helical portion formed around an intake valve and a substantially straight inlet passage portion tangentially connected to the helical portion. A bypass passage is branched off from the inlet passage portion and connected to the helical portion. A rotary valve is arranged in the bypass passage and actuated by a vacuum operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of an engine is increased beyond a predetermined value. The rotary valve comprises a valve holder, a valve shaft rotatably supported by the valve holder, and a valve body formed in one piece on the valve body and extending across the bypass passage. The valve shaft and the valve body are made of a polymer such as a rubber or synthetic resin.

Abstract: A catalytic converter includes a tubular casing within which is held a monolithic catalyst body which is generally of a columnar shape. The ends of the monolithic catalyst body are each engaged with a cushion ring, and each cushion ring is engaged with a retainer ring therefor, which is substantially axially fixed within the casing near to an end thereof. The monolithic catalyst body is supported within the casing by axial compressive force present between the retainer rings on the outside, the cushion rings between the retainer rings, and the monolithic catalyst body between the cushion rings.

Abstract: A fuel injection apparatus for a multi-cylinder internal combustion engine, having a single fuel injection valve arranged above a throttle valve. A collector member arranged in a throttle bore of the engine so that the member faces the fuel injection nozzle. A cam and link mechanism adapted for connecting the collector member and a throttle shaft, so that a position of the collector member with respect to the axis of the throttle bore changes in accordance with the degree of the opening of the throttle valve. Therefore, an air fuel mixture having a constant air fuel ratio is supplied to all cylinders of the engine.

Abstract: An attaching construction for attaching an ignition coil device to the external surface of an internal combustion engine, in which a coil side bracket is mounted to the ignition coil device, an engine side bracket is mounted to the external surface of the internal combustion engine, and a layer, formed of a resilient rubber-like elastomer with low heat conductivity and high temperature resistance, is provided to extend between the coil side bracket and the engine side bracket, so as to join them, and thereby to mount the ignition coil device to the internal combustion engine.
