A method for customizing a local map with a grid that can be rotated and zoomed includes the steps of (a) defining a grid on a map; (b) generating a grid set-up data as a function the defined grid; and (c) employing a computer based device in a manner to receive the grid set-up data and convert a geographical coordinate to a local coordinate on the map. A device for such use includes a computer based device having a processor, a memory operably association with the processor, a power source, means for receiving a geographical coordinate; and geographical coordinate conversion software operably disposed in the memory and operably associated with the processor in a manner to in a manner to receive grid set-up data and convert the received geographical coordinate to a local coordinate on the map.

A monolithic refractory ceramic tube sheet for use in all-ceramic air-to-air indirect heat exchangers, the heat exchanger used in all temperature and all pressure applications. A method for forming the monolithic tube sheet includes casting a refractory ceramic in a mold, where portions of the mold comprise the housing of the heat exchanger. Precisely formed negatives are used to form through channels and vacancies within the tube sheet, which are precisely positioned within the mold allowing uniform and flush formation of openings which receive the ceramic tubes therein. The same mold is used to provide both tube sheets of a tube sheet pair allowing accurate alignment of tubes within the exchanger vessel resulting in ease of assembly and equal loading of tubes when in use.

An intensely colored transparent and/or translucent paper has chroma c and brightness L, as measured by a Hunterlab instrument, which measures the Cartesian coordinates a, b, L of a point P of color and its polar coordinates H and c. The paper is such that the ratio of c to L is higher than 30%, preferably higher than 50%. The paper contains a colorant in the stock, preferably 5 to 10% by weight of liquid coloring agent in relation to the weight of the finished paper. The colorant is a coloring agent which fixes directly in the cellulose. The paper is suitable for printing and/or writing.
摘要:
A computer program displays a virtual environment and a character in the virtual environment. The character includes a body and a replaceable head. Player control signals from an input device control replacement of the character's replaceable head and other character actions in the virtual environment. The computer program may attribute play characteristics to the character based on the head in place on the character at a given time. These characteristics may be thematically consistent with the displayed appearance of the head in place. The program may allow a player to select a set of character heads for use with the character. The program may allow the player to collect heads from the virtual environment and store the collected heads for use. The program may offer communication with other connected computer systems facilitating a multi-player or on-line interact hosted game.
摘要:
This invention provides improvements in certain processes for alkylating amino acids whereby yields based on amino acid are improved. More specifically, the invention provides a process for the preparation of amino acid derivatives in free acid or salt form, in which the nitrogen atoms of two or more amino acid molecules are linked by a hydrocarbyl or substituted hydrocarbyl group, which comprises reacting, in an aqueous medium at a pH in the range 7-14, a compound of the formula X—A—Y where X and Y are halo atoms which may be the same or different and A is a hydrocarbyl or substituted hydrocarbyl group, in which X and Y are attached to aliphatic or cycloaliphatic carbon atoms, with an amino acid (or salt thereof), wherein the reaction is carried out in the presence of dissolved cations of an alkaline earth metal or of a transition metal and/or wherein the unreacted amino acid is recovered and recycled.

A method of installing a pivoting tone arm and associated support assembly on a turntable support assembly such that a stylus mounted on said tone arm is properly aligned relative to revolving turntable, comprising the following steps:fixedly attaching a tone arm support assembly base plate to a surface of said turntable support assembly,pivoting said tone arm into vertical alignment with an alignment nipple removably mounted on a spindle extending from the turntable; andadjusting the position of said tone arm support assembly relative to said base plate until a designated opening in a tone arm headshell is vertically aligned with said nipple.
摘要:
A chemical vapor deposition system which includes a generally closed reaction chamber having walls formed from a dielectric material. A susceptor for carrying a plurality of semiconductor wafers is positioned within the chamber. An induction coil is positioned in the vicinity of the susceptor for carrying an alternating electric current to produce induction heating of the susceptor and thereby heating the back side of the wafers thereon. Low frequency induction heating and variations in susceptor thickness are used to produce uniformity of temperature. Boundary control arrangement between the susceptor surface and wafer surfaces are used to improve deposition uniformity. A coating is formed on wall portions of the reaction chamber facing the susceptor and wafers carried thereon for reflecting heat energy radiated from the susceptor and the wafers positioned thereon back to the susceptor and the wafers to reduce substantially the heat loss therefrom and thereby to reduce substantially the thermal gradient from front to back surfaces of the wafers.
