摘要： An engine comprising an intake port which has a separating wall projecting downwardly from the upper wall of the intake port. The separating wall defines a helical portion, an inlet passage portion tangentially connected to the helical portion, and a bypass passage interconnecting the inlet passage portion and the helical portion. The upper wall of the bypass passage is higher than that of the inlet passage portion. A rotary valve is arranged in the bypass passage and is actuated by a vacuum-operated diaphragm apparatus. The rotary valve is opened when the amount of air fed into the cylinder of the engine is increased beyond a predetermined value.

摘要： 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.

摘要： A helical type intake port is formed with the helical portion around an intake valve and the inlet portion tangentially contiguous to the helical portion.A bypass passage is provided in a cylinder head, which is branched off from the inlet portion and connected to an end portion of said helical portion. The flow in the bypass passage is controlled by a valve in response to the amount of air in the intake port so that a strong swirl flow with a slight flow resistance may be obtained at not only a low revolution and a low load, but also at a high revolution and a high load.

摘要： In a fold-up type of portable telephone device, the casing to be opened/closed has liquid crystal display devices on its front and back sides, which causes occurrence of noise. In view of this, in the liquid crystal display device of a portable telephone device, a flexible connection substrate is used to integrally form first and second liquid crystal display parts with a driver circuit shared therebetween. The first liquid crystal display part is connected to the flexible connection substrate to which the second liquid crystal display part is connected. The second liquid crystal display device is formed by adding the flexible connection substrate to the first liquid crystal display part, and both are driven by the driver circuit. Not only an alternative display but also simultaneous displays can be selectively performed.

摘要： A lean NOx reduction catalyst capable of reducing NOx through reaction of H.sub.2 with NOx at low temperatures below 350.degree. C. is installed in a downstream portion of an exhaust pipe of an internal combustion engine in or near a muffler. Such an NOx reduction catalyst comprises, for example, Pt/zeolite catalyst. An H.sub.2 generator is installed so as to supply the H.sub.2 to an inlet side of the NOx reduction catalyst. The H.sub.2 generator may include a reforming catalyst for reforming methanol, LPG, or natural gas to generate H.sub.2. The generated H.sub.2 flows to the NOx reduction catalyst where it reacts with NOx to purify the exhaust gas.

摘要： In an air-fuel ratio feedback control system including at least one air-fuel ratio sensor downstream of a catalyst converter provided in an exhaust gas passage, an actual air-fuel ratio is controlled in accordance with the output of the downstream-side air-fuel ratio sensor. When at least one of the air-fuel ratio feedback control conditions for the downstream-side air-fuel ratio sensor is not satisfied the controlled air-fuel ratio is made an air-fuel ratio by an open loop control, while all the air-fuel ratio feedback control conditions for the downstream-side air-fuel ratio sensor are satisfied the controlled air-fuel ratio is made the stoichometric ratio (.lambda.=1) in accordance with the output of the downstream-side air-fuel ratio sensor. For a period after all the air-fuel ratio feedback control conditions for the downstream-side air-fuel ratio sensor are satisfied, the control by the output of the downstream-side air-fuel ratio sensor is prohibited, but, the controlled air-fuel ratio is made the stoichiometric ratio (.lambda.=1) by an open loop control or by the output of an upstream-side air-fuel ratio sensor.

摘要： Improved greases for use in homokinetic joints are proposed which comprise a base oil, a thickening agent, and an organic molybdenum compound. Greases comprising a base oil, a thickening agent, an organic molybdenum compound, and an organic zinc compound are also proposed. These greases exhibit smaller friction coefficients than conventional greases used for this purpose. On the homokinetic joint lubricated with the grease according to the present invention, the axial force produced is reduced and vibrations generated on the engine are absorbed. The vehicle is prevented from vibrating. The use of an expensive organic metallic extreme-pressure additive is unnecessary.
