Abstract:
A base for planar servo motor which is defined with a hollow space for reducing the weight of the base. Thereby, when the base is hung upside down, the base can be prevented from being deformed by its own weight, and the load of a machine table for supporting the base can be relatively reduced, so as to avoid causing vibration of the machine table. In addition, the hollow space can reduce the material for manufacturing the base, so that the cost is reduced.
Abstract:
A gantry with adjustable torsion leaf springs which utilizes a plurality of superposed torsion leaf springs to connect a beam and two supporting members and to absorb the variation quantities of the displacement error of the supporting members. By such arrangements, the absorbed variation quantities can be changed simply by adjusting the amount of the torsion leaf springs, thus meeting the requirements of different machines.
Abstract:
A method for maintaining address mapping for a flash memory module is disclosed including: recording a first set of addresses corresponding to a first set of sequential logical addresses in a first section of a first addressing block; recording a second set of addresses corresponding to a second set of sequential logical addresses in a second section of the first addressing block; recording a third set of addresses corresponding to a third set of sequential logical addresses in a first section of a second addressing block; and recording a fourth set of addresses corresponding to a fourth set of sequential logical addresses in a second section of the second addressing block; wherein the second set of logical addresses is successive to the first set of logical addresses, and the third set of logical addresses is successive to the second set of logical addresses.
Abstract:
A biomaterial prepared from a process comprising dehydrating the fish scales until the fish scales containing less than about 50% of water, and grinding the dehydrated fish scales into ground particles each having an average size of less than about 10,000 μm in diameter, wherein the ground particles contain a mixture of sponge like matrix and powder is provided. The invention also provides a biomaterial prepared from fish scales by a process comprising subjecting the fish scales to a heat treatment at a temperature of less than about 200° C.
Abstract:
A linear table with an adjustable dust-proof structure is locked with a loading rack on each end of a stator by screw, and each end of an elongated sheet-like dust-proof structure is located on each of the two loading racks. As compared to the conventional plate-like dust-proof structure, the weight of the dust-proof structure of the present invention is widely reduced, thus avoiding the problem of structure bending downwards. Moreover, adjusting the distance between the two loading racks can adjust the strain of the dust-proof structure, further preventing the dust-proof structure from bending downwards.
Abstract:
A method for preparing a biomaterial comprising the steps of acellularizing the fish scale to remove cell components, decalcifying the fish scale; and cleaning the fish scale, wherein in the step of acellularizing, it further including stirring constantly the fish scale in a solution comprised of an octylphenoxypolyethoxyethanol, a tris-buffered salt and a protease inhibition; and rinsing in a Hanks' buffered saline and the fish scale keeps the naturally 3-dimension microstructure after the step of acellularizing the fish scale.
Abstract:
The invention comprises a memory module capable of wear-leveling. In one embodiment, the memory module comprises a flash memory and a controller. The flash memory comprises a plurality of management units, wherein each of the management units comprises a plurality of blocks. The controller receives new data with a logical address managed by a first management unit selected from the management units, pops a first spare block from a spare area of the first management unit, determines whether an erase count of the first spare block is greater than a first threshold value, searches a second management unit selected from the management units for a replacing block with an erase count lower than a second threshold value when the erase count of the first spare block is greater than the first threshold value, and directs the first management unit and the second management unit to exchange the first spare block with the replacing block.
Abstract:
A method of preparing a biomaterial comprises steps of acellularizing the fish scale, decalcifying the fish scale, and cleaning the fish scale and then extruding the fish scales.
