The pressure sores prevention bed according to this invention consists of two parts arranged in an alternated fashion. Parts A (1) and Parts B (2) are moved upward and downward by the lifting sets C (3), M (10), and F (6), N (11). While Parts A (1) are at the lowered position, Parts B (2) support the patient's entire weight, and the patient's skin does not touch Parts A (1). While Parts B (2) are at the lowered position, Parts A (1) support the patient's entire weight, and the patient's skin does not touch Parts B (2). The lifting sets C (3) and F (6) are controlled by the control set D (4) which has a timing switch which can be set for a period of 1-30 minutes, with a circuit breaking system provided. The pressure sores prevention bed according to this invention also includes the system for inclining the head end of the bed and the system for tilting the head rest at the angle of 10-15°.

As the traffic volume carried by telecommunication networks has been rapidly increased as a result of the bandwidth-intensive applications such as Internet access, electronic commerce, multimedia applications, and distributed computing, it is imperative to utilize the optical network for backbone, metropolitan, and local area networks. The optical networks employing optical fibers as the transmission medium have exhibited a superior performance / cost ratio for both long-haul and short-haul routes and the emerging dense wavelength division multiplexing (DWDM) / all-optical networks have shown a promising potential to improve speed, capacity and connectivity of optical telecommunication networks. The present invention provides Micro-Opto-Electro-Mechanical Waveguide Switch (MOEM-WS) by integrating MEMS actuators and micromachined PLCs on the same substrate. The MOEM-WS is an integrated hybrid microsystem: Micro-Opto-Electro-Mechanical System (MOEMS) and it is particularly applicable for optical cross-connect (OXC) switches and optical add / drop multiplexers (OADM). The MOEM-WS can provide an essential fiber switching capability for DWDM / all-optical networks with numerous accompanying benefits such as low cost, small crosstalk, reliability, compactness, high speed, reconfigurability, modularity, scalability, and insensitiveness to signal wavelength and polarization.

A method for preparing nano metallic particles comprises the steps of dipping a conductive substrate in an electroplating solution containing metallic ions and performing an electroplating process to form the nano metallic particles on the conductive substrate by the reduction reaction of the metallic ions. The nano metallic particles can be used as a catalyst to perform a chemical vapor deposition process to form carbon nanotubes on the conductive substrate. Subsequently, fluorescent material can be positioned on the carbon nanotubes to form a light-emitting device. When a predetermined voltage is applied between the conductive substrate and the fluorescent material, the carbon nanotubes on the conductive substrate emit electrons due to the point discharge effect, and the electrons bombard the fluorescent material to emit light beams.

In an oil pump structure of an automatic transmission using a torque converter, a hydraulic pressure chamber is defined by a pump housing and a pump cover, to rotatably accommodate therein inner and outer rotors. First and second inflow ports respectively communicating with an oil strainer and a control valve are formed in the outside surface of the pump cover separately from each other. First and second oil inflow passages communicating with the respective inflow ports, a merged-flow portion that downstream portions of the first and second oil inflow passages are merged with each other, a downstream-side oil distribution channel intercommunicating a downstream side of the merged-flow portion and the hydraulic pressure chamber, are formed in at least one of the pump housing and the pump cover.

The present invention provides ink for forming a catalyst layer containing at least a cation conductive polymer electrolyte, catalyst-supporting particles including conductive carbon particles and an electrode catalyst supported thereon, and a dispersion medium, wherein the polymer electrolyte has a mean inertia radius of 150 to 300 nm. A catalyst layer made of the catalyst layer ink improves in gas diffusion property and increases cell voltage, which allows providing a proton conductive polymer electrolyte fuel cell capable of maintaining the high cell voltage for a long time.

Etch assisting agents for focused ion beam (FIB) etching of copper for circuit editing of integrated circuits both prevent loss of adjacent dielectric due to sputtering by the ion beam, and render sputtered re-deposited copper on adjacent surfaces non-conductive to avoid electrical short circuits. The agents are characterized by having an N—N (N being Nitrogen) bonding in their molecules and boiling points between about 70° C. and about 220° C., and include hydrazine and water solutions, hydrazine derivatives, NitrosAmine derivatives saturated with two hydrocarbon groups selected from Methyl, Ethyl, Propyl and Butyl, NitrosAmine related compounds, and Nitrogen Tetroxide. Preferred agents are Hydrazine monohydrate (HMH), HydroxyEthylHydrazine (HEH), CEH, BocMH, BocMEH, NDMA, NDEA, NMEA, NMPA, NEPA, NDPA, NMBA, NEBA, NPYR, NPIP, NMOR and Carmustine, alone or in combination with Nitrogen Tetroxide. The agents are effective for etching copper in high aspect ratio (deep) holes.
