(Abstract)
"A supercharging arrangement for an internal combustion engine. The supercharging arrangement comprises a supercharger having a rotational drive input, and a transmission having a rotational drive input to receive drive from an internal combustion engine, and a rotational drive output connected to the input of the supercharger. The transmission includes a variator（可変装置）operatively connected（動作可能に結合）between the input and the output of the transmission, which variator has an output（出力部）that is driven at an operating ratio from an input（入力部）. A control system operates to cause an engine to deliver an amount of torque that is indicated by the state of an input to the control system. The control system is further operative to set（設定するよう動作）the operating ratio of the variator."

(Abstract)
"A variable device（可変装置）for regulating the outlet pressure of a fluid from a valve body, includes a pressure-sensing chamber having a wall formed by a resilient self-restoring diaphragm which is responsive to pressure（＊無冠詞）in the chamber. A valve element connected to the diaphragm controls flow（＊無冠詞）into the chamber. Increased pressure（＊無冠詞）in the chamber decreases the flow into the chamber and decreasing pressure increases flow whereby fluid flow（＊無冠詞）out from the chamber is maintained at a desired pressure（＊不定冠詞）. The outlet pressure is adjusted by deflecting the diaphragm in a direction to open the valve while permitting a section of the diaphragm connected to the valve member to remain responsive to the pressure（＊定冠詞）in the chamber. An adjustment cover is provided to adjustably deflect the diaphragm and includes a catch mechanism to allow adjustment of the fluid outlet pressures and also retain the device at a desired value. An indicator arrangement may be provided to visually indicate the fluid outlet pressure."

(Abstract)
"An internal combustion engine is provided. Facing pistons eliminate a cylinder head, thereby reducing heat losses through a cylinder head. Facing pistons also halve the stroke that would be required for one piston to provide the same compression ratio, and the engine can thus be run at higher revolutions per minute and produce more power. An internal sleeve valve is provided for space and other considerations. A combustion chamber size-varying mechanism（燃焼室容積可変機構）allows for adjustment of the minimum size of an internal volume to increase efficiency at partial-power operation. Variable intake valve operation is used to control engine power."
