Title: Tappet device in internal combustion engine
Inventor: INOUE KAZUO
IPC: F01L13/00
Filed: 1985-07-31
Abstract: PURPOSE:To aim at reducing the fuel consumption of an engine during running at a low speed, by providing two rocker arms which are made into contact with high and low speed cams, respectively, so that both rocker arms are coupled with each other when the engine runs at a high speed while the coupling between both arms are released when the engine runs at a low speed. CONSTITUTION:When an engine runs, for example, at a low speed, the coupling between first and second rocker arms 7, 8 is released by a coupling change-over means 21. That is, hydraulic pressure in a hydraulic pressure chamber 29 is released so that a stopper 24 is moved toward the first rocker arm 7 by means of a spring 25, and a piston 23 is retracted until it abuts against a stepped part 27. Then, the abutting surfaces of the piston 23 and the stopper 24 correspond to the sliding surfaces of both rocker arms 7, 8 so that both rocker arms 7, 8 fall in such a condition that they are angularly displaced relative to each other. As a result, both arms are swung corresponding to the sliding operation thereof with high and low speed cams 3, 5 in anociation with the rotation of a cam shaft 2. Accordingly, both intake valves 1a, 1b are opened and closed having timings and lifts which are different from each other.

Title: Stirring mixer
Inventor: YAMAMOTO SEIKICHI
IPC: E02F5/02
Filed: 1986-07-17
Abstract: PURPOSE:To construct a continuous underground wall having high reliability by a method in which a plurality of stirring and mixing parts of a stirring mixer are turned in mutually opposite directions to uniformly mix soil with a solidifying agent by stirring. CONSTITUTION:The upper stirring and mixing parts 15 and the lower stirring and mixing parts 16 of a stirring mixer 4 are turned in mutually opposite directions to mix soil while excavating pits, where soil is sufficiently mixed with a solidifying agent jetted from nozzles 37a and 38a uniformly. The same operations are repeated by shifting the position of the mixer 4 under the ground to construct a continuous underground wall. Since the soil is mixed uniformly with the solidifying agent by stirring, the continuous underground wall having high strength and free of water leakage can be constructed.

Inventor: WATANABE HIDEO
IPC: F02D41/02
Filed: 1989-06-29
Abstract: PURPOSE:To have stable stratified combustion without being influenced by cycle variation by locating an injector and the gap of ignition plug on the cylinder head side combustion chamber in such an arrangement as on one straight line at a certain spacing, igniting the atomized fuel passing at the time of low load, and thereby accomplishing stratified combustion.

Immediately before the ignition timing in the later haft of a compression stroke while the condition is such as described above, the fuel is injected from an injector 20 in conformity to the fuel injection signals at the fuel injection start timing and the fuel injection ending timing. Thereby the atomized fuel is ignited always when it passes through the gap of ignition plug 21 while the load control is performed with the mixture gas air-fuel ratio. This accomplishes stratified combustion in good performance.
