A middle electric motor drive unit for an electric bicycle, including a motor, a controller, a sensor, a gear reducer, a one-way clutch, a chain tightener, and a housing. The middle electric motor drive unit is disposed below a frame of the electric bicycle, and in the vicinity of a pedal shaft thereof. The middle electric motor drive unit is independent from the pedal shaft with respect to functions and structure. The motor is an internal rotor and permanent magnet DC motor. The motor shaft of the motor is parallel to a gear shaft and the pedal shaft. The controller is built-in, and disposed in or on the housing. The sensor is an internal sensor or an external pedal shaft sensor.

A handset device (10) includes a housing (20) and a battery cover (30) mounted on the housing. The housing includes a front wall (24), a rear wall (22), two sidewalls (26), and at least one bay cooperatively surrounded by the front wall, the rear wall, and the sidewalls. The front wall includes at least one first receiving portion (240) including a wedge-shaped first slidable groove (242) having a first inclination angle and a recessed portion (244) communicating with the first slidable groove. The rear wall includes at least one receiving groove (220). The battery cover includes at least one fastening protrusion (34) corresponding to the first receiving portion and at least one protrusion (32) received in the receiving groove. The fastening protrusion has an inclination angle equal to the first inclination angle and includes a hook located at an end thereof, abutting the recessed portion.
摘要:
A wrapper for a smoking article includes nanoparticle spinel ferrite catalyst and a web including cellulosic fibers and an optional web-filler. The web-filler can be a modified web-filler which incorporates the spinel ferrite catalyst. The nanoparticle spinel ferrite catalyst can be a nanoparticle manganese-copper-iron oxide catalyst incorporated in the wrapper and/or a tobacco cut filler. Also provided is a smoking article including a cigarette tobacco rod having a wrapper including a web, a web-filler, and a nanoparticle spinel ferrite catalyst, the web-filler optionally supporting the nanoparticle catalyst. A method of making the wrapper and a method of making a smoking article utilizing the wrapper are also provided.
摘要:
Polynucleotides useful for improvement of plants are provided. In particular, polynucleotide sequences are provided from plant sources. Polypeptides encoded by the polynucleotide sequences are also provided. The disclosed polynucleotides and polypeptides find use in production of transgenic plants to produce plants having improved properties.
摘要:
Cut filler compositions, cigarettes, methods for making cut filler compositions and cigarettes, and methods for treating mainstream tobacco smoke of cigarettes are provided that use catalyst particles capable of converting carbon monoxide to carbon dioxide. The catalyst particles are supported on tobacco powder. The tobacco powder supported catalyst particles can be prepared by dry admixing the catalyst particles and tobacco powder or by combining a dispersion of catalyst particles with the tobacco powder.
摘要:
The invention relates to an isolated nucleic acid encoding a humanized immunoglobulin that has binding specificity for α4β7 integrin and comprises the complementarity determining regions (CDRs) of mouse Act-1 antibody. The present invention further relates to an isolated nucleic acid encoding a humanized heavy chain and an isolated nucleic acid encoding a humanized light chain. The invention also relates to recombinant vectors and host cells that comprise a nucleic acid which encodes a humanized immunoglobulin, humanized immunoglobulin heavy chain or a humanized immunoglobulin light chain, and to methods of preparing a humanized immunoglobulin.
