The present invention is directed to an infrared light assembly (10, 30, 80, 90). A preferred embodiment of the light assembly (10, 30, 80, 90) may be used on aircraft or other vehicles for landing, taxi mode, or search operations. The light assembly (10, 30, 80, 90) preferably only requires about 10 to 20 watts of power. The light assembly (10, 30, 80, 90) may include a housing (12, 32, 82), a base (14, 34, 50), an IR diode (16, 36, 60), and an aspheric lens (18, 38). The base (14, 34, 50) is preferably connected to the bottom portion (22) of the housing(12, 32, 82), and the aspheric lens (18, 38) is preferably connected to the top portion (24) of the housing (12, 32, 82). The IR diode (16, 36, 60) may be mounted on the base (14, 34, 50). The housing (12, 32, 82) and the base (14, 34, 50) preferably have high thermal conductivity, and they preferably act as heat sinks. In addition, a plurality of thermal electric coolers (20, 40, 70) may be positioned between the base (14, 34, 50) and the IR diode (16, 36, 60) for additional dissipation of the heat generated by the light assembly. The IR diode (16, 36, 60) is adapted to emit infrared light. The light assembly (10, 30, 80, 90) preferably maintains a substantially constant operating temperature so that the peak emission of the IR diode (16, 36, 60) is substantially maintained. The infrared light may radiate through the hollow of the housing(12, 32, 82) to the aspheric lens (18, 38). The aspheric lens (18, 38) is preferably adapted to collimate infrared light. As a result, the light assembly (10, 30, 80, 90) may provide a collimated beam of infrared light having a NVIS radiant intensity greater than about 2.

An electro-optical device includes a first substrate, a second substrate and a liquid crystal, and has a display region and a peripheral region. The peripheral region of the first substrate has a peripheral electrode and a first orientation film covering the peripheral electrode. Then, since the density of first orientation film in the display region is different from the density of the first orientation film in the peripheral region, it is possible to efficiently capture ionic impurities present in the liquid crystal.

A stock ejector assembly and method for metal forming dies includes a stock ejector with a large spring and a ring-style stripper. The ring-style stripper provides a larger surface area for contacting the stock. The large compression spring is preloaded and when a load is applied, the stripper retracts and the spring pressure increases. When the dies separate, the stock ejector pushes the part off flat surfaces, separating surfaces sealed by adhesion, including but not limited to oil or lubricant adhesion.

A silicon wafer, which has been doped with nitrogen and has been subjected to an extrinsic gettering (EG) treatment, for example, the formation of a polysilicon layer. In the silicon wafer, when the wafer is exposed to an ion of a heavy metal such as copper or nickel in a device manufacturing process, the copper and nickel can be captured by the action of intrinsic gettering (IG) in the course of a heat treatment, and, when a polysilicon layer is formed as a strain layer, iron and copper can be captured by the action of an extrinsic gettering (EG) using the polysilicon as a strong point for the capture.

As an object to provide a lithium-ion supercapacitor having a high energy density and a high power density, capable of being charged and discharged many times, and having a long product life, there is provided a lithium-ion supercapacitor using a graphene/CNT composite electrode, the lithium-ion supercapacitor including: an anode; a cathode that is arranged to be separated from the anode; and a lithium ion electrolytic solution that fills in a space between the anode and the cathode, wherein either or both of the cathode and the anode are formed by a graphene/CNT composite, and a CNT concentration in the graphene/CNT composite is 17 wt % or more and 33 wt % or less.

In an ion generating unit configured to control driving of a plurality of ion generating elements for generating ions by a controller, the controller drives the ion generating elements upon start up, and is configured to keep driving for a predetermined time period; thereby, the ion concentration of a space upon start up is quickly raised to a predetermined concentration. Further, the controller is configured to drive the ion generating elements intermittently and one after another in order after the predetermined time period has elapsed; the product life is elongated while maintaining the predetermined ion concentration and shortening the driving time of the ion generating elements.

An adhesive hydrogel contains: a polymer matrix of a copolymer of a monofunctional monomer and a crosslinking monomer (a); another polymer component; water; and a polyhydric alcohol, wherein: either a structural unit derived from the monofunctional monomer contained in the polymer matrix or the other polymer component or both contain a structural unit derived from at least one compound (b) selected from the group consisting of ethylenically unsaturated carboxylic acids, ethylenically unsaturated carboxylic acid salts, and ethylenically unsaturated carboxylic acid derivatives having a hydroxyl group, an acid group, a salt thereof, an amino group, and/or an ammonium group; and the other polymer component contains a polymer compound (c) with a side chain having an oxyalkylene group or a polyoxyalkylene group.

An ultra capacitor module includes a first ultra capacitor having a first polar terminal provided with a screw thread A formed on an outer peripheral surface, a second ultra capacitor having a second polar terminal provided with a screw thread A formed on an outer peripheral surface, and a connecting member having a screw hole B formed corresponding to the screw thread A on an inner peripheral surface through which the first polar terminal is inserted from one side and the second polar terminal is inserted from the other side to connect the first and second ultra capacitors in series and having a gas emission hole formed from a center to an outer surface.

A propeller for watercraft having excellent abrasion resistance includes a propeller body having a blade and a hub portion, the propeller body being molded by casting an aluminum alloy, and an anodic oxide coating provided so as to cover a surface of the propeller body, the anodic oxide coating being obtained by performing a blast treatment for the surface of the propeller body and thereafter subjecting the surface to anodic oxidation.

An intrauterine device having at least one first pharmaceutically active ingredient and at least one first layer made of at least a first polymeric material, wherein between about 10 and about 60 v/v % of at least one particulate material is dispersed and/or incorporated in the first polymeric material. The presence of the particulate material will reduce the porosity of the polymer or otherwise obstruct the diffusion of the pharmaceutically active ingredient being released, thereby slowing its rate of release. In this way, it is possible to regulate the release rate and/or initial burst of the device, simply by adjusting the amount of particles/particulate material in the first layer, instead of having to adapt the size of the device to the desired release pattern, which requires expensive changes in production equipment and manufacturing processes.
