Abstract:
The present invention relates to an optical medium judging method for avoiding the collision of an objective lens with a disk or the failure to judge a warped disk when the optical disk drive judging the disk. This method will move the objective lens so as to obtain the data of the laser beam reflection amount of the focusing beam on the plastic layer of the optical disk. By using the reflection amount, the driving circuit will output a rising direct current voltage of a voltage difference to drive an actuator so as to move the objective lens to a proper position capable of judging the disk without colliding with the disk.

Abstract:
An apparatus and method for reproducing energy in an engine driving system, the driving system has an engine with several cylinders and an cooling device connected to the engine, the cooling device has at least one water tank for outputting cooling water to the engine and inputting heated cooling water from the engine. A separator chamber connected to the engine and the water tank. When the heated water flows into the separator chamber from the engine, part of the heated water is decomposed into oxygen and hydrogen. The oxygen and hydrogen is delivered to the water tank from the separator chamber. A storage chamber store the oxygen and hydrogen from the water tank and deliver them to the cylinders of the engine as a reproduced fuel in order to enhance combustion and reduce the emitting of the exhaust of the engine.
Abstract:
An engine device includes a pressure regulator coupled to the engine, a container, and a needle tube mechanism disposed in the container and having a block coupled to the engine with a pipe, to receive gas from the engine. The block includes a slit connected to the pipe and a channel communicating with the slit and the chamber of the container, the slit of the block includes an inner diameter smaller than that of the channel of the block, and arranged to allow the gas from the engine to flow through the slit and the channel of the block when the engine is over-pressurized, and to allow the gas in the container to flow into the engine in order to balance a pressure in the engine when the pressure in the engine is too low.
Abstract:
An engine device includes a water tank coupled to an engine to supply cooling water to the engine and having a mouth disposed in the upper portion. A separator housing is coupled between the water tank and the engine to receive heated water and vapor or air from the engine, the separator housing is coupled to the mouth with a tube to supply the vapor and the air from the separator housing to the upper portion of the water tank, and then to supply the vapor and the air to the engine. A lid is engageable onto the mouth for enclosing the orifice of the mouth and includes an aperture coupled to the tube, to receive the vapor and the air from the separator housing.
