摘要:
A high conductance, multi-tray solid precursor evaporation system coupled with a high conductance vapor delivery system is described for increasing deposition rate by increasing exposed surface area of solid precursor. The multi-tray solid precursor evaporation system includes a base tray with one or more upper trays. Each tray is configured to support and retain film precursor in, for example, solid powder form or solid tablet form. Additionally, each tray is configured to provide for a high conductance flow of carrier gas over the film precursor while the film precursor is heated. For example, the carrier gas flows inward over the film precursor, and vertically upward through a flow channel within the stackable trays and through an outlet in the solid precursor evaporation system.

To provide an optical waveguide and an optical transmitting and receiving module able to perform a transmitting operation and a receiving operation simultaneously, wherein a linearly first waveguide 21 that one side is coupled to an optical fiber 3 and the other side is coupled to a light receiving element 4, and a second waveguide 22 that one side is coupled so as to make an acute angle θ with the side of the first waveguide 21 to be coupled to the light receiving element 4 and the other is coupled to a light emitting element 5 are provided. By controlling a shape of the second waveguide 22, the receiving signal light from the optical fiber 3 is received to the light receiving element 4, and is not guided to the second waveguide 22. Therefore, the receiving operation and the transmitting operation can be preformed at the same time. Namely, when the transmitting optical signal is the incident of light from the light emitting element 5 to the second waveguide 22, the optical signal is guided by the second waveguide 22 toward the first waveguide 21, coupled to the first waveguide 21, and guided toward the optical fiber 3.

A nanometer size roughened structure is formed on a surface of a light-emitting element, and luminous efficiency is improved. The roughened structure on the surface of the light-emitting element of the invention is formed into the following shape such that the refractive index smoothly changes: (1) the mean diameter of projections on the roughened surface is smaller than the light wavelength; (2) a pitch of the roughened surface is irregular; and (3) positions of the top and bottom of the roughened surface are distributed from their mean values within the light wavelength in order to give a smooth gradient of the refractive index. The surface of such light-emitting element is obtained by forming a thin film on the surface of the light-emitting element using a resin composition which contains a block copolymer or graft copolymer and forms a micophase-separated structure in a self-organization manner; selectively removing at least one phase of the microphase-separated structure of the thin film formed on the surface; and etching the surface of the light-emitting element using the remaining phase as an etching mask.

An apparatus for aiding a machinist in preparing a machining program. A machining simulator simulates a basic machining program. Values of machining variables are obtained during the simulation and stored in a simulation result data memory. A spindle load determiner, a cutting speed determiner, and a rotating speed determiner analyze the machining variable values of a certain machining process to determine the machining efficiency of that process. A navigation information memory stores a plurality of messages for giving advice on how to change the cutting conditions. A message, which depends on the analysis of the machining variable values, is selected from the memory and is shown on a display. Accordingly, an operator can easily modify the basic machining program by following the message on the display, even if the operator does not have much knowledge or experience.

摘要:
In the NH3 injection rate control method for an NOx removal apparatus, operating area of the apparatus is divided into first area in which molar ratio of NH3 injection rate with respect to NOx flow rate at an inlet of the apparatus is smaller than molar ratio at minimum point where NOx concentration assumes minimum value and second area in which the molar ratio is equal to or larger than the minimum point molar ratio, and virtual NOx concentration with respect to the molar ratio is set according to virtual characteristic line which varies monotonically to stride across desired operating point without rising with increase of the molar ratio from the first area to the second area. Moreover, feedback control is implemented for adjusting the NH3 injection rate with respect to the NOx flow rate in direction that the virtual NOx concentration is brought close to the desired NOx concentration.
