Provided is a bubble control unit for a liquid ejecting head which ejects liquid from a nozzle formed on a nozzle surface. The bubble control unit includes a liquid channel through which the liquid is supplied to the nozzle. In the bubble control unit, the liquid channel includes: a first chamber; a second chamber disposed on the upstream side from the first chamber; a first communicating path which has a bubble chamber extending upward from the first chamber, and makes the liquid within the second chamber to flow into the first chamber from a first communicating path inlet of the second chamber; and a second communicating path which is provided with a second communicating path inlet below the first communicating path inlet, separately from the first communicating path inlet, and makes the liquid within the second chamber to flow into the first chamber from the second communicating path inlet.

A compiler apparatus, which can perform software pipelining optimization that has a considerable effect of reducing the number of execution cycles taken to complete a loop process, converts a source program into a machine program for a processor which is capable of parallel processing. The compiler apparatus is composed of: a parsing unit operable to parse the source program and then to convert the source program into an intermediate program which is described in an intermediate language; an optimization unit operable to optimize the intermediate program; and a conversion unit operable to convert the optimized intermediate program into the machine language program, wherein the optimization unit is operable to execute software pipelining, by inserting a transfer instruction, which is used for transferring data between operands, into a loop process included in the intermediate program so that a data dependence relation is changed.

An ORACLE based umbrella data import / export method is characterized in that when data are imported, a main process (program) reads the external data into a memory in batch in the form of memory arrays, an encapsulated OCI data exchange interface is called to resolve the memory arrays in batch, and the resolved memory arrays are imported into a temporary table special for transactions; after the external data are imported into the temporary table, the umbrella imported API based on the temporary table uses the user-defined ORACLE function or process as the parameter to be executed by calling the umbrella imported API, the external data are dispersed in a plurality of user-defined physical tables, and the user-defined ORACLE function or process defines the dispersion of the data in the temporary table; the internal data are exported in batch: when the data are exported, the encapsulated OCI data exchange interface is called to read the internal data into the memory in the form of memoryarrays, and the memory arrays are exported in batch; and after the internal data are exported into the memory arrays, the umbrella exported API based on the multi-dimensional memory chip uses the user-defined ORACLE function pointer as the parameter to be executed by calling the umbrella exported API, and the internal data are exported into a plurality of files in a disperse manner.

A method of fabricating a semiconductor device includes forming a gate insulating film on an upper surface of a silicon substrate, forming a polycrystalline silicon film on the gate insulating film, and etching the polycrystalline silicon film, the gate insulating film, and the silicon substrate with a patterned coating type carbon film and a silicon nitride film so that first and second trenches are simultaneously formed. The first trench has a first width and a first depth and the second trench has a second width larger than the first width and the second depth larger than the first depth.
