Abstract:
Liquid is flash evaporated in a series of cells along and surrounding an exhaust duct to generate a pressurized vapor where at least one of the surfaces is in communication with the source of heat sufficient to maintain the surface at a temperature such that the liquid injected into the chamber is substantially instantly converted to a superheated vapor with no liquid pooling within the chamber. The liquid is introduced by controlled injectors operating at a required rate. Each of the cells is periodically discharged by a pressure controlled relief valve and the vapor from the cells combined to form a continuous stream feeding a turbine or other energy conversion device. The outer wall of the cell is offset so that it contacts the inner wall at one point around the periphery. Heat transfer ribs and bars can be provided in the duct to provide increased heat transfer where necessary.
Abstract:
A transducer assembly is provided for projecting acoustic signals into a medium. The assembly includes a support member having first and second layers of piezoelectric material mechanically linked to the support member. The first and second layers are joined to electrical drive circuitry such that one layer receives a driving voltage signal while the other layer receives the driving voltage with a stiffening voltage. The transducer assembly can use both the 3-1 and 3-3 drive modes. Multiple configurations are supported, and both bender bar and slotted cylinder configurations are shown.
Abstract:
An evaporator includes a vaporization chamber having a monomer inlet and a vapor outlet. There is a vapor nozzle in the vapor outlet. The evaporator also includes a collar positioned between the vaporization chamber and the vapor nozzle which increases the pressure in the evaporation chamber while the conductance through the nozzle is substantially unchanged.
Abstract:
This invention provides a vaporizer that prevents deterioration of a precursor while reducing a residue, reducing risk of clogging, and easily increasing vaporization flow. The vaporizer comprises an inlet port (P1) for introducing a precursor in a liquid phase or a gas-liquid mixture phase, a vaporizing section (3) for vaporizing the precursor arranged on the downstream side of the inlet port (P1), and an outlet port (P2) for delivering the precursor vaporized at the vaporizing section (3), wherein the vaporizing section (3) is of a flow channel type comprising a nozzle (31) for spraying the precursor and a heating channel (32) arranged on the downstream side of the nozzle (31) continuously thereto. A plurality of vaporizing sections (3) are arranged in parallel between the inlet port (P1) and the outlet port (P2), and arranged such that each vaporizing section (3) can distribute the precursor independently of each other.
Abstract:
A micro-evaporator is disclosed which is easy to manipulate and can be operated problem-free over a large temperature range. The micro-evaporator has micro-evaporator channels in a trapezoidal region, comprising an inlet region opening in the liquid feed chamber with a small diameter, and an outlet region opening into the vapor collecting chamber with a large diameter.
Abstract:
Disclosed herein is a delivery device comprising a chamber; a gas inlet; a gas outlet; and a dip tube contained within the chamber and having an upper portion and a lower portion, the upper portion of the dip tube being in fluid communication with the gas inlet and being operative to permit the entry of a carrier gas; the lower portion of the dip tube extending into the chamber, the lower portion of the dip tube terminating in an outlet end; and a sleeve; where the sleeve has a first end and a second end; the first end being in an interference fit with the lower portion of the dip tube; and where the sleeve vibrates upon being subjected to a disturbance.
