Abstract: A method of forming a wear-resistant reinforcing coating on a substrate, such as concrete, wood, metal or particulate. A reinforcing fiber mat is placed on the substrate and a liquid matrix material is mixed with small colored stones. The mixture of matrix material and stones is poured onto the mat, and the liquid wets the mat and contacts the substrate. After curing, a composite coating is formed with stones as the wearing surface. A membrane can be interposed between the substrate and the reinforcing coating to prevent adhesion and “starving” of the mat.

Abstract: A method for forming an underfill layer on a bumped wafer is disclosed. A film is provided wherein the film includes a base layer, a removable layer and the underfill layer. The film is disposed on a bump wafer and then pressing the film under heating is performed to have the bumps of the wafer embedded in the underfill layer. Then, the removable layer with base film attached thereto is removed, so the underfill layer well encloses the bumps of the wafer and is easily separated from the base film layer and the removable layer without damaging the bumps formed on the wafer.

Abstract: A method for backside grinding a bumped wafer is disclosed. A wafer has a plurality of bumps formed on the active surface thereof. Prior to grinding the back surface of the wafer, a hot-melt adhesive layer is formed on the active surface of the wafer so as to be adhered to the active surface and cover the bumps. Also a grinding film is attached to the hot-melt adhesive layer. After grinding the back surface of the wafer, the grinding film is removed but the hot-melt adhesive layer is remained on the wafer for the following wafer-dicing step.

Abstract: Multi-layered semiconductor nanoparticles having a very narrow grain-size distribution and exhibiting a spectrum having a narrow wavelength-width peak are prepared by a manufacturing method combining a monodisperse semiconductor nanoparticle manufacturing method and a multi-layer semiconductor nanoparticle preparation method. The nature of a solution of monodisperse semiconductor nanoparticles that is stabilized by a surface stabilizer is transformed between hydrophilic and lipophilic by substituting the surface stabilizer. The stabilized semiconductor nanoparticles are then shifted between an aqueous layer and an organic layer. The semiconductor nanoparticles are coated with multiple layers in the organic layer, and the organic layer is drawn off to recover the semiconductor nanoparticles therefrom.

Abstract: A novel furniture leg glide is disclosed for reducing a screeching sound made by a furniture leg being dragged across a floor. The furniture leg glide is formed from a hollow body portion having an end cap disposed thereon with a flexible coupling formed along the hollow body portion between first and second ends thereof. A piece of felt type material is bonded to the end cap and the flexible coupling permits the piece of felt type material to contact the floor when the furniture leg is angularly displaced in relation to the floor within a predetermined number of degrees. The flexible coupling flexes and compresses in relation to the angular movement of the furniture leg. In accordance with another embodiment of the invention a furniture leg glide is provided for attaching to a furniture leg having a swivel base furniture leg glide disposed thereon.

Abstract: An RTD system includes multiple pluralities of RTDs and RTD bank assembly to which each plurality of RTDs are connected. Each RTD bank assembly includes a current source for the RTDs connected thereto, a multiplexer switching system for switching the current source successively between the RTDs, and a measurement function for measuring the voltage drop across the RTDs produced by the current source. The system includes a circuit for determining resistance of the RTD from the current applied thereto and the voltage drop there across. The system further includes a plurality of low pass filters associated, respectively, with each RTD, wherein the low pass filters are charged before the voltage measurement is made. The system includes a precharging arrangement where the low pass filter associated with the next RTD in a voltage sampling sequence is precharged, so that the delay between sampling of the voltage from the low pass filters associated with successive RTDs is significantly reduced.

Abstract: From a supply reel which is set in position at an ACF (Anisotropic Concuctive Film) feeding station, an ACF tape having an ACF laminated on one side of a liner tape is drawn out by an ACF bonding means. At least two reel mount members are provided on a reel stand at the ACF feeding station to mount two ACF tape supply reels concurrently thereon. The reel stand is connected to a switch means thereby to switch the two reel mount members either to an operating or tape supplying position or a standby position. As soon as an ACF tape from a supply reel in the operating position is consumed completely, a fresh supply reel in the standby position is switched into the operating position to continue the supply of the ACF tape.

Abstract: A drawn down chuck for gripping the inner or outer diameter of a workpiece. The chuck includes rotatable jaws disposed in a chuck body. The rotatable jaws helically and then linearly retract into the chuck body to secure workpieces having a shaft and an enlarged offset such as a hub or flange proximate to the end of the shaft. Cam assemblies interact with the jaw rods to provide the helical and linear movement. The cam assemblies include a cam groove and a cam follower, wherein the cam groove has a linear and a helical segment. The cam follower is operatively engaged on the cam groove as the jaw rod moves between the extended and retracted position so that when the jaw rod is retracted it first moves helically and then axially.

Abstract: The object of the present invention is to propose an etch channel sealing structure characterized by excellent impermeability to moisture and resistance to temporal change of the diaphragm in the pressure sensor produced according to the sacrificial layer etching technique, and to provide a pressure sensor characterized by excellent productivity and durability. After a very small gap is formed by the sacrificial layer etching technique, silicon oxide film is deposited by the CVD technique or the like, there by sealing the etch channel. Further, impermeable thin film of polysilicon or the like is formed to cover the oxide film. This allows an etch channel sealing structure to be simplified in the pressure sensor produced according to the sacrificial layer etching technique, and prevents entry of moisture into the cavity, thereby improving moisture resistance. Moreover, sealing material with small film stress reduces temporal deformation of the diaphragm.

Abstract: A direct braking of a drive shaft for a tracked vehicle that moves on rotating track(s). A disc brake is connected to the same drive shaft that has sprocket(s) for engaging the track(s). Upon activation by a vehicle driver, opposing pistons engage the disc to retard rotation of the drive shaft. This, in turn, causes slower rotation of the tracks and slower movement of the vehicle.
