Film forming apparatus and method

Abstract: An atomic layer deposition (ALD) apparatus capable of forming a conformal ultrathin-film layer with enhanced step coverage is disclosed. The apparatus includes an ALD reactor supporting therein a wafer, and a main pipe coupled thereto for constant supply of a carrier gas. This pipe has two parallel branch pipes. Raw material sources are connected by three-way valves to one branch pipe through separate pipes, respectively. Similarly, oxidant/reducer sources are coupled by three-way valves to the other branch pipe via independent pipes. ALD works by introducing one reactant gas at a time into the reactor while being combined with the carrier gas. The gas is “chemisorped” onto the wafer surface, creating a monolayer deposited. During the supply of a presently selected material gas from its source to a corresponding branch pipe, this gas passes through its own pipe independently of the others. An ALD method is also disclosed.

Spill prevention system with safety valves

Abstract: The present invention is for a spill prevention system to prevent fuel spills from a connecting line connecting duel fuel tanks on a truck when the connecting line is severed or detached from one of the reducer fittings to which it is attached. The connecting line provides pressure communication between the fuel tanks so that fuel flows from one tank to the other whenever there is an unequal pressure acting on the fuel, which occurs whenever one tank has more fuel in it than the other. The connecting line connects to the reducer fitting located on each fuel tank. A safety valve is immersed in the fuel in each tank and connected to the reducer fittings. Each safety valve is configured to shut off flow to the connecting line when the connecting line is severed or detached from the one of the reducer fittings.

A Self-Actuating Traction-Drive Speed Reducer

Abstract: Traction-drive speed reducers offer certain advantages over geared speed reducers. In particular, they generally run quieter than geared units and provide an opportunity for higher efficiency by eliminating sliding motion between contacting elements. In order to generate a sufficiently high output torque, some means must be provided to create a normal force between the rolling elements. This normal force, along with the friction coefficient, enables the device to transmit torque from one rolling member to the next. The speed reducer proposed here is designed so that the configuration of the rolling elements creates the needed normal force in response to the torque exerted back on the system by the downstream loading. Thus the device is self-actuating. Since the normal force is only present when needed, the rolling elements of the device can readily be disengaged, thus eliminating the need for a separate clutch in the drive system. This feature can be exploited to design a transmission with several distinct speed ratios that can be engaged and disengaged in response to changing speed requirements.
