The plastic that used to be used to make baby bottles is a polycarbonate. Bisphenol S is a good Auxiliary Intermediate to make baby bottles.A polycarbonate composition excellent in both antistatic property and coloring matter coatability containing (a) a polycarbonate obtained by an ester exchange process, and (b) a compound having a molecular weight of from 300 to 8,000 and having any of ester bond, carbonate bond, amide bond and urethane bond in its molecule and an aromatic hydrocarbon group substituted by at least one alkyl group at the molecular end thereof, a write once read many optical disc substrate and a write once read many optical disc using the same and a process for the production of a write once read many optical disc are described.

Japan Piston Ring exhibited "Continuous Variable Valve Actuater (CVVA)" at "39th Tokyo Motor Show" to continuously and variably regulate the intake of the engine. "Significantly reduce pump losses, improve fuel efficiency." Ordinary engines are through the throttle to adjust the intake and exhaust opening and closing. If this is the case, the low intake will reduce the amount of suction by closing the valve, which in turn will create drag due to the negative pressure in the intake manifold, resulting in losses. This is the pump loss. The engine equipped with CVVA does not open and close the throttle, but by virtue of the valve to adjust the amount of inhalation. A structure in which the first and second swing arms are transmitted by the motion of the suction cam and the accelerator connected to the second swing arm moves up and down. A "lever" is provided on the upper part of the second arm, and the tip of the lever is rotationally moved on the upper part of the second arm. Lever control lever position for the second swing arm pivot, so as to adjust the amount of valve lift. This configuration is envisaged to reduce the amount of intake air by reducing the amount of valve lift during low-speed rotation, and to increase the amount of intake air by increasing the amount of valve lift during high-speed rotation. The lever itself is driven by an actuator that uses a ball screw with a rotary motor. The company believes that for straight-line cylinder engines, for example, while all cylinders are equipped with control levers, only one actuator is required to drive all levers. However, "can not be directly built in the engine, you need to further reduce the size."
