摘要:
A road surface comprising a blend of at least two aggregate materials disposed in a binder matrix and having different rates of wear as judged by the aggregate test B.S.812 1967, each aggregate material comprising individual aggregate particles of a size such that they will be retained on a British Standard 1/4 inch sieve, or its metric equivalent, and will pass through a British Standard 3/4 inch sieve, or its metric equivalent, and having a surface micro-texture in the range defined by asperity heights of a minimum texture depth of 5 microns and a maximum texture of 500 microns, the individual aggregate particles being disposed in the binder matrix so that the shortest distance between any two adjacent particles is 1 to 6 mm and the texture depth of the aggregate particles in the binder matrix is between 1 and 5 mm, of which the following is a specification.

A tire having a tread with improved wet grip characteristics. The tread is made from a composition which has specific loss factor values measured in high and low frequency ranges defined herein.
摘要:
An integrated leadframe and bezel structure includes a planar carrier frame, a plurality of bonding leads, a die pad region, and a bezel structure. The bezel structure includes a bending portion shaped and disposed to facilitate a portion of said bezel structure being bent out of the plane of said carrier frame. A sensor IC may be secured to the die pad region, and wire bonds made to permit external connection to the sensor IC. The bezel structure includes portions which are bent such that their upper extent is in or above a sensing surface. The assembly is encapsulated, exposing on the top surface part of the bezel portions and the upper surface of the sensor IC, and on the bottom surface the contact pads. Two or more bezel portions may be provided, one or more on each side of the sensor IC.
摘要:
The present invention provides a coating for glass substrates and the like which resists accumulation of dirt and water stains. Coated glass substrates of the invention can be used in insulated glass units wherein the coating of the invention is carried on an exterior surface of one pane of glass while a reflective coating is applied on the opposite side of the same pane of glass.
摘要:
A gravity motor using the potential energy of an initial mass located at a relative height. This potential energy can be converted into kinetic energy. This gravity motor comprises a storage bin (26) able to contain a quantity of fragmented material (39) and having a base (28) with a first chute (30) to take the fragmented material (39) out of the base (28), a second chute (34) with an exit (58) and a guiding cylinder (32) of the exit (58), a wheel (60) with vanes (61) that rotate a rotor (46). While rotating, each vane (61) can collect a volume of the fragmented material (39) and act as a torque around a central axis, thus causing the rotation of the wheel around the central axis, at a velocity corresponding to the kinetic energy of the volume of the fragmented material (39). The rotor (46) comprises means for articulated fastening to a machinery part.
摘要:
An apparatus usable for cleaning foreign material from the internal and external surfaces of a part, including a container of particulate media, a vibration generator for the container which creates an amplitude and frequency which will fluidize the media, and means for suspending the part in the fluidized media. The suspending means is vibrated at an amplitude and frequency different from the amplitude and frequency of the container whereby the fluidized media will clean the foreign material from the internal and external surfaces of the part.
摘要:
A tire stud comprises a cylindrical body portion having embedded in one end and protruding therefrom a cylindrical tip of hard wearing material for engaging a road surface. The stud is designed to reduce road surface damage without significantly affecting the grip of the stud on the road surface.
摘要:
A biometric sensor device, such as a fingerprint sensor, comprises a substrate to which is mounted a die on which is formed a sensor array and at least one conductive bezel. The die and the bezel are encased in a unitary encapsulation structure to protect those elements from mechanical, electrical, and environmental damage, yet with a portion of the sensor array and the bezel exposed or at most thinly covered by the encapsulation or other coating material structure.
摘要:
Transparent articles comprising transparent, nonmetallic substrate and a transparent film stack is sputter deposited on the substrate. The film stack is characterized by including at least one infrared reflective metal film, a dielectric film over the metal film, and a protective silicon nitride film of 10 Å to 150 Å in thickness over the said dielectric film. The dielectric film desirably has substantially the same index of refraction as does silicon nitride and is contiguous with the silicon nitride film.
