An SOI wafer including an active semiconductor material layer on an insulating layer is processed to form thereon first and second active semiconductor regions that respectively have different thicknesses and that are vertically and laterally insulated. In the process, a trench is etched into the SOI wafer, seed openings are formed in the bottom of the trench to reach the underlying active material layer, the trench is filled with epitaxially grown semiconductor material progressing from the seed openings, some of the epitaxially grown material is removed to form the second active regions, and oxide layers are provided so that the second active regions are laterally and vertically insulated from the first active regions formed by remaining portions of the active semiconductor material layer.

A portable water disinfecting and purification apparatus comprising a first chamber into which water to be purified may be drawn by suction or negative pressure, a second chamber into which the water from the first chamber can be forced by a pumping action or positive pressure, whereby the water is initially passed across a pre-filter secured over the inlet to the first chamber and having a very small pore size and an inner cavity in which a disinfecting agent is place to filters most contaminants before the water is drawn into said filtering device, and once in the first holding chamber the water is isolated and may be further treated with a disinfectant agent, and then is passed though at least additional filtering substance including an activated carbon or nano-filter.

The present invention relates to a test chamber that can be used to perform a variety of X-ray and neutron spectroscopy experiments including powder diffraction, small-angle scattering, X-ray absorption spectroscopy, and pair distribution functions, such chamber comprising a first electrode with an X-ray transparent window; a second electrode with an X-ray transparent window; a plurality of insulating gaskets providing a hermetic seal around the sample and preventing contact between said first and second electrodes; and an insulating housing into which the first electrode is secured.

The present invention relates to a system and a method of measuring a physiological variable in a body. A basic idea of the present invention is to measure a physiological variable in a body by means of employing a sensor (314) which is arranged to be disposed in the body for measuring the physiological variable. The sensor must be provided with a supply voltage in order to be operable. Therefore, a control unit (322) disposed outside the body provides this supply voltage to the sensor. The control unit also receives, from the sensor, via a wired connection (311), signals that represent the physiological variables that are measured. The control unit is arranged with a communication interface (401, 701) and a modulator (301) for wireless spread spectrum communication of the measured physiological variables for presentation purposes.

A liquid crystal display uses a pixel division method by which the size of a defect can be reduced much more than conventionally possible, and a defect correcting method for the liquid crystal display. The liquid crystal display is provided with an active matrix array substrate including a plurality of gate lines and a plurality of source lines arranged on a transparent substrate so as to intersect with each other, and a plurality of pixel electrodes arranged in a matrix, each pixel electrode including an assembly of a plurality of sub-pixel electrodes, separate TFTs respectively connected to the sub-pixel electrodes in the vicinity of an intersection portion of the gate line and the source line, the TFTs being driven by the common gate line and the common source line, and at least one opening portion being formed in a lower-layer side line placed in a lower layer at the intersection portion.

Disclosed are electro-hydraulic brake system and control method. The system may include a braking input unit to provide a braking input according to an operation of a driver, a control unit to control generation of braking oil pressure according to the braking input of the braking input unit, a pressure generating unit to generate the braking oil pressure, wheel clamping units to generate braking forces to corresponding wheels, and oil supply lines to transfer the braking oil pressure to corresponding wheel clamping units. Each oil supply line is fluidly connected to the pressure generating unit. For each oil supply line, a split valve is installed in a connection portion of the pressure generating unit and the oil supply line. When the split valve is closed, the split valve blocks the braking oil pressure supplied from the pressure generating unit to the oil supply line.

The invention discloses a novel roller bit sealing ring, which belongs to the field of bearing sealing. The novel roller bit sealing ring is disposed in a sealing groove between a bearing shaft hole and a tooth palm journal. Both ends of the sealing groove are respectively communicated with an inside lubricating oil channel and an outside drilling fluid channel. The novel roller bit sealing ring comprises a metal framework fixed in the sealing groove, the metal framework separates the sealing groove into a lubricating oil sealing groove communicated with the inside lubricating oil channel and a drilling fluid sealing groove communicated with the outside drilling fluid channel. A lubricating oil sealing part is disposed in the lubricating oil sealing groove and completely seals and separates the inside lubricating oil channel together with the metal framework. A drilling fluid sealing part is disposed in the drilling fluid sealing groove and completely seals and separates the outside drilling fluid channel together with the metal framework. The novel roller bit sealing ring is more suitable for severe environment of drilling work, and capable of more effectively and simultaneously separating lubricating oil and drilling fluid, rock debris and the like. Separation of lubricating oil and separation of drilling fluid do not affect each other, and service life of a sealing device is prolonged.

The present invention provides a low-noise MEG apparatus of high sensitivity. A MEG apparatus using a magnetic shield of high critical temperature superconductor is set on the floor of a building via mechanical vibration suppressor supports to prevent appearance of noise signals. Also, the apparatus is equipped with means for preventing any relative displacement between the SQUID magnetic sensors and the magnetic shield of high critical temperature superconductor, thereby not letting an inevitable mechanical vibration of least strength produce any variable components of the trapped static magnetic field, which the SQUID magnetic sensors could be sensitive to.

The invention relates to a fully anti-ultraviolet, anti-fatigue, and anti-malignant melanoma optical protective material. The optical protective material is characterized by comprising the following materials in percentage by weight: 0.010 to 30.000 weight percent of additive and the balance of base stock, wherein the additive is a fluorescent whitening agent and / or an ultraviolet absorber, and also No.beta-1 decomposition antireflective agent, color-changing agent and / or toner can be added into the additive and the base stock. The optical protective material has the effect of full ultraviolet protection, namely 100 percent of ultraviolet UV400 protection, can prevent harmful light from causing human body to generate malignant melanoma, avoid human fatigue, furniture color change and embrittlement caused by the harmful light, particularly has better advanced protective effect on infants, students and young ladies, and can protect tender skin and slow down the aging process.
