An apparatus for and method for providing easy and rapid conversion from a first fuel to a second fuel in a gas appliance. The gas appliance has a variable fuel valve controlled by a microprocessor. A table stored in non-volatile memory has an entry for each of the fuels to be burned in the gas appliance. The table entries are empirically determined at the time of manufacture.

Process for hydrolyzing starch with alpha-amylase in which aqueous starch hydrolyzable by alpha-amylase, a water-insoluble calcium compound as an alpha-amylase thermostabilizing agent, and an alkali metal orthophosphate buffering agent are combined with an alpha-amylase preparation for a time sufficient to allow hydrolysis of the starch to occur.

A semiconductor device with two selectable manufacturing configurations, comprising: a first module layer having a plurality of circuit blocks; and a second module layer positioned substantially above the first module layer, wherein in a first selectable configuration a plurality of memory circuits are formed to control a portion of the circuit blocks, and wherein in a second selectable configuration a conductive pattern is formed to control substantially the same portion of the circuit blocks.

A size-convertible device for supporting wafers in a parallel relationship includes a removable insert that enables the device to be non-destructively switched from providing edge support for large diameter wafers to providing edge support for small diameter wafers. The insert maintains the original wafer pitch and the original insertion angle. In the preferred embodiment, the device is a Front Opening Unified Pod (FOUP) specifically designed for use with 300 mm diameter wafers. Inserts are rele...

A three-dimensional semiconductor device with two selectable manufacturing configurations includes a first module layer having a plurality of circuit blocks; and a second module layer formed substantially above the first module layer, wherein in a first selectable configuration a plurality of memory circuits are formed to store instructions to control a portion of the circuit blocks, and wherein in a second selectable configuration a predetermined conductive pattern is formed in lieu of the memo...

The present invention first provides a high-density accommodations module which is vertically convertible from parallel bedding to staggered-seating configurations. The respective configurations are more specifically established by at least one set of vertically-paired, reconfigurable accommodations compartments, each having in each of its associated configurations an upper-torso section and a lower-torso section. In the bedding configuration, prone postures are accommodated by a mutually-horizo...
