Abstract: Several embodiments of induction systems for internal combustion engines wherein each chamber of the engine is served by a relatively long low speed induction passage and a relatively short high speed induction passage. The arrangements of the passages is such that the change in length is achieved quite simply by positioning a throttle valve at the upstream end of the short induction passage and having both passages communicate with an air inlet device. Several embodiments of throttle valve arrangements are also disclosed wherein a single throttle valve can control the flow through two adjacent induction passages.

Abstract: The can end is formed with a circular severing score for severing the area defined thereby from the can end by pulling a manipulating tab secured within the area defined by the score at a position adjacent thereto. In order to increase the pressure resisting strength against the internal pressure caused by the content in the can, the can end is made from a thin aluminum alloy sheet having the yield strength in the range of 24-29 kgf/mm.sup.2 as well as the elongation equal to or greater than 6%, while the aperture rate defined by the ratio of the area formed within the score with respect to the total area of the can end is made at least equal to or greater than 60% so that the pressure resisting strength is kept substantially at least 5 kgf/cm.sup.2. In order to more advantageously maintain the high pressure resisting strength of the can, score is located at a position spaced from the inner periphery of the bottom of the frustoconical portion at least a distance equal to or greater than 1 mm inwardly of the area of the can end, to make the inner radius of curvature of the corner formed around the inner periphery of the bottom of the frustoconical portion equal to or less than 0.5 mm, and to make the taper angle of the frustoconical portion of the can end equal to or less than 10.degree.. An auxiliary score having a score residual smaller than that of the score for severing the area defined thereby from the can end may be formed outwardly or inwardly of the score for severing. The score residual of the can end may be preferably increased from the thinnest portion adjacent to the position where the tab is provided while a plurality of elongated ridges or grooves may be formed within the area defined by the score substantially perpendicular to the line passing through the tab and the center of the can end in order to avoid rapid severing of the area defined by the score from the can end so as to prevent spilling of the content out of the can when the can end is being opened. All these measures are effective to most advantageously enhance the pressure resisting strength of the can end.

Abstract: An internal combustion engine and method of operating it that improves combustion efficiency, fuel economy and exhaust emission during low speed running. The engine is equipped with a relatively conventional main induction system and an auxiliary induction system having a substantially smaller cross sectional area for delivering a charge to the chambers of the engine at a high velocity to improve turbulence and combustion efficiency. A control valve arrangement is incorporated so that the idle and low speed requirements are supplied through the auxiliary induction system and the medium and higher load charge requirements are supplied primarily through the main induction system. An exhaust gas recirculating system is incorporated for reintroducing exhaust gases to the combustion chamber so as to reduce the emissions of nitrous oxide. A control arrangement is incorporated so that the exhaust gases are recirculated only at the time when the auxiliary induction system is supplying the primary portion of the charge requirements. A fuel enrichment system is also incorporated for providing a richer than normal fuel air-mixture at such time as exhaust gases are being recirculated. An arrangement is also incorporated for advancing the spark ignition at the time the exhaust gases are being recirculated and when the main induction system begins to supply a large portion of the engine charge requirements.

Abstract: An internal combustion engine having a relatively large main induction system that supplies the engine charge requirements at partial and full load and a relatively small cross-sectional area auxiliary induction system that provides the charge requirements at idle and low load conditions. An exhaust gas recirculating system is also incorporated with a control whereby exhaust gases are recirculated to the engine combustion chambers only at the time when the auxiliary induction system is supplying the major portion of the engine charge requirements. This permits effective combustion control without necessitating modifications to the conventional spark timing device of the engine.

Abstract: A coordinate input device includes a casing having an upper surface and a lower surface which are not parallel to each other. A columnar position designating member is disposed within the casing. The angle of the position designating member as viewed from the upper surface is different from that as viewed from the lower surface. One of the upper surface and the lower surface is placed on a tablet. The coordinate input device thus designates and inputs coordinates while determining which surface of the casing is placed on the tablet. At least one of the designating positions of the position designating member is located in the vicinity of an edge of one of the upper surface and the lower surface, and an indicator is provided at a portion corresponding to the designating position. Thus, information on the tablet designated by the position designating member can be input regardless of which surface of the casing is placed on the tablet, thereby enhancing ease of operation of the coordinate input device.

Abstract: The present invention relates to a T-shaped connection frame for connecting car frames, in which a first member is connected to a second member via a joint member to form a "T." The joint member is formed by symmetrically dividing a rectangular tube between its two latch teeth located at the upper-center and lower-center inner walls. The rectangular tube also has protrusions at the left and right exterior walls. The joint member divided in this way has the latch teeth at the upper and lower tips of the mouth formed by the division and has the protrusion situated opposite the mouth so that the first member can be snapped on easily to this mouth and the second member can be attached to the protrusion at the opposite side. This structural arrangement makes the positioning of the frames very simple, obviates a make-shift attachment, and, at the same time, reduces the number of operation steps.

Abstract: An induction system for an internal combustion engine that improves efficiency through increasing flame propagation at low and medium speeds and loads. This is accomplished through the use of a relatively small cross sectional area auxiliary induction system through which at least a portion of the charge requirements are supplied. The small cross sectional area causes the charging to be introduced at a high velocity, thus increasing turbulence in the intake charge to promote rapid flame propagation when the spark plug is fired. At least a portion of the idle charge is also delivered through the main induction passage so as to reduce the velocity of the intake charge. The charge delivered through the main induction system flows at an angle to that discharged from the auxiliary induction system so that the two flow paths will create internal turbulence due to their different directions.

Abstract: Several embodiments of internal combustion engines each having an arrangement for increasing turbulence in the combustion chamber under at least certain load and/or speed conditions so as to permit the use of a relatively simple spark advance mechanism. In each embodiment, the flame propogation is controlled by controlling the degree of turbulence to achieve the desired effect. The turbulence is generated by causing induction of at least a portion of the engine charge requirements through a relatively small cross sectional area auxilliary induction passage. Because of the small cross sectional area, high flow velocities are generated which are maintained in the combustion chamber. In accordance with certain embodiments of the invention, the degree of turbulence is controlled by either shunting some of the air flow through the main induction passage or by introducing controlled amounts of exhaust gas products. In accordance with another embodiment of the invention, the associated distributor is provided with two pairs of contact points each of which provides a different spark advance and a control circuit for selecting the appropriate set of contact points to set the particular running condition of the engine.
