摘要:
In warming up operation when the temperature of an engine is low, heat release in a combustion chamber is delayed by making ignition timing immediately before the top dead center of compression stroke or later. Hereby, exhaust gas including a large quantity of unburned HC, oxygen and carbon monoxide is exhausted into an exhaust passage. Then, the mixture of the HC, oxygen and carbon monoxide is accelerated by a turbulence generating means for generating turbulence in an exhaust flow mounted in the exhaust passage. Hereby, the HC is combusted in the exhaust passage, exhaust temperature is raised, resulting in that effective reduction of the HC. As the exhaust temperature is raised, it can activate earlier a catalytic converter for purifying exhaust.

An object of the present invention is to provide an electro conductive tin oxide powder which is free from toxic dopant, e.g., antimony, which can provide excellent conductivity to a polymer, and easy to disperse in a paint and the conductive film formed shows excellent transparency; and also provide the method for producing an electro conductive tin oxide powder. In order to achieve the above objects, the present invention disclose the electro conductive tin oxide powder which is characterized in that it is free from a dopant and the paint prepared with it gives conductive film which shows a Haze value of 5% or less and surface resistance of 1010Ω/ or less. The electro conductive tin oxide powder is produced by the method which is characterized in that steps for production are, adding a sodium stannate solution slowly into an aqueous acid solution till the solution pH goes down to 5 or under; followed by rinsing, followed by filtering and drying the resulting slurry and milling of the resulting dry powder and calcining of the milled powder in a non-oxidizing atmosphere.

To present a method of manufacturing a multipitch screw easily by using flat dies suited to mass production. A flat die 4 includes linear ordinary screw threads 40a, and multipitch screw threads 40b consecutive to the ordinary screw threads 40a, slightly shorter in height than the ordinary screw threads 40a, with both side walls formed alternately and consecutively, alternating between a section departing from the central line 40c of screw threads and an approaching section along a central line 40c, and symmetrically to the central line 40c of screw threads. After forming the tacks of a constant lead angle screw on the outer circumference of a shaft-like blank piece by the ordinary screw threads 40a, tracks of a multipitch screw are formed by the multipitch screw threads 40b, and therefore the tracks of a multipitch screw varying in the force applied at the time of rolling can be formed easily.

To balance ignition retard for reduction in exhaust and increase in exhaust gas temperature at a start of cooling, and increased output under a full open condition. There are provided an upward spray that forms airflow toward an electrode portion of an ignition plug at a start of cooling, a central spray oriented toward the electrode portion of the ignition plug by the airflow by the upward spray, and lateral sprays that prevent fuel from adhering to a wall surface under a full open condition and form uniform air/fuel mixture.

In a starting time in which an air motion is little, a means for heightening the motion is added, from the starting time a stratification combustion operation is enabled to carry out, and a discharge of an unburned fuel is minimized. From the starting time of an engine (from the first combustion cylinder) it is possible to carry out a stable stratification combustion. In accordance with the stratification combustion in the exhaust air, a large quantity of the surplus oxygen remains. In the engine in the exhaust stroke twice (two times) fuel injection is carried out and the after-burn phenomenon is caused in the exhaust port and then the exhaust gas temperature can be raised.

摘要:
An input interface circuit for a semiconductor integrated circuit device is provided which includes a pair of diodes, first, second, and third PMOSFETs, and first, second, and third NMOSFETs. The diodes serve to clamp a high positive or negative voltage input at a level that is the sum of the power supply voltage and the forward voltage of the diodes or the difference between the ground potential and the forward voltage. The first and second PMOSFETs are connected in series between the power supply and an inside input terminal coupled to an internal circuit element of the semiconductor integrated circuit device. The first and second NMOSFETs are connected in series between ground and the inside input terminal. The third PMOSFET is connected in series between the outside input terminal and a gate of the first PMOSFET. The third NMOSFET is connected in series between the outside input terminal and a gate of the second NMOSFET. The voltage which is intermediate between ground potential and the voltage of the power supply is applied to a gate of each of the first NMOSFET, the second PMOSFET, the third PMOSFET, and the third NMOSFT. This structure serves to protect the circuit elements against an input of an undesirable higher positive or negative voltage to the input interface circuit.
