20080273989 | MULTI-STAGE GAS COMPRESSING APPARATUS - A multi-stage gas compressing apparatus comprises a primary gas compressor and a secondary gas compressor. A gas compressed in the primary gas compressor is transferred to the secondary gas compressor in which the gas is further compressed. A detector detects upper and lower limits of discharge pressure from the secondary gas compressor, and a signal is sent from the detector to a control device connected to the primary and secondary gas compressors. Then, the primary and secondary gas compressors are started or stopped by the control device. | 11-06-2008 |
20080314459 | CHECK VALVE FOR A COMPRESSOR - A compressed gas is introduced from a compressor into a inlet of a check valve. In a cylindrical casing of the check valve, a valve seat is provided and has a plurality of paths through which compressed gas flows from the inlet to an outlet of the check valve. The paths are opened and closed by a valve disc. A deformation limiting member is provided on the valve disc to limit a gap between the valve disc and the valve seat. | 12-25-2008 |
20090047159 | Multi-stage gas compressing apparatus - A compressed gas compressed by the first gas compressor is further compressed by the second gas compressor. The compressed gas from the first gas compressor is sent to a crank case of the second gas compressor in which the gas is further compressed. The gas is sent to a cylinder of the second gas compressor and compressed by a piston in the cylinder. | 02-19-2009 |
20090207172 | COMPRESSION SYSTEM, PROGRAM AND METHOD - An object is to calculate an accurate motion vector with a small computational effort. To this end, provided is a system for compressing a motion picture generated by projecting objects onto a screen, the objects moving relatively to the screen in a 3D space, the system including: a motion calculating component which calculates a motion vector of the object within the screen by projecting onto the screen a motion of the object in the 3D space between a time corresponding to a compression target frame and a time corresponding to another frame; and a compressing component which compresses the compression target frame by motion compensation based on the motion vector. | 08-20-2009 |
20090313451 | METHOD OF MEMORY MANAGEMENT FOR SERVER-SIDE SCRIPTING LANGUAGE RUNTIME SYSTEM - A method of operating a memory system includes allocating a portion of a memory unit in a computing system as a memory heap. The heap includes a metadata section and a plurality of segments, each segment having a segment size. The method also includes creating a free list array and class-size array in the metadata section, the class-size array being created such that each element of the size-class array is related a particular one of the plurality of segments and the free list array being created such that each element of the free list array is related to a particular size class, receiving a first memory allocation request for a first object, determining that the first object is a small object, assigning a class to the first object, identifying a first segment to place the first object in by examining the size-class array, subdividing the first segment into multiple portions, determining a first head portion of the first segment, the first head portion representing the first open portion of the segment and being determined by examining the free list array, allocating the first head portion for the first object, receiving a command indicating that a transaction is complete, and clearing the free list array and the size-class array upon receipt of the command. | 12-17-2009 |
20110081262 | MOTOR-DIRECTLY CONNECTED COMPRESSOR UNIT - To provide a motor-directly connected compressor unit which is equipped with a cooling means for suppressing the heating of the compressor and is easy to transfer without upsizing the compressor unit in size or weight, the compressor unit is configured such that a sirocco fan | 04-07-2011 |
20120204164 | ADAPTIVE NEXT-EXECUTING-CYCLE TRACE SELECTION FOR TRACE-DRIVEN CODE OPTIMIZERS - An apparatus includes a processor for executing instructions at runtime and instructions for dynamically compiling the set of instructions executing at runtime. A memory device stores the instructions to be executed and the dynamic compiling instructions. A memory device serves as a trace buffer used to store traces during formation during the dynamic compiling. The dynamic compiling instructions includes a next-executing-cycle (N-E-C) trace selection process for forming traces for the instructions executing at runtime. The N-E-C trace selection process continues through an existing trace-head when forming traces without terminating a recording of a current trace if an existing trace-head is encountered. | 08-09-2012 |
20130042092 | MERGE OPERATIONS OF DATA ARRAYS BASED ON SIMD INSTRUCTIONS - A method and apparatus are provided to perform efficient merging operations of two or more streams of data by using SIMD instruction. Streams of data are merged together in parallel and with mitigated or removed conditional branching. The merge operations of the streams of data include Merge AND and Merge OR operations. | 02-14-2013 |
