摘要:
The present invention provides a method for patent valuation, comprising steps of providing a patent group for establishing a citation network and selecting a cluster within the citation network, wherein the citation network comprises a plurality of links, each link is formed between any two patent cases having citation relationship with each other; afterwards, designating weighting value for each link connecting each pair of patent cases; finally, calculating a plurality of centrality indices with respect to the plurality of patent cases in the cluster respectively according to the weighting value of each link. By means of the method of the present invention, it is capable of obtaining a relative value or significance of a specific patent case with respect to the other patent cases within the cluster.
摘要:
A photosensitive drum for image forming apparatus includes an inner roller, an outer roller and a photoelectric conversion layer. The inner roller of circular cylindrical shape is formed by a cathode substrate. The outer surface of the circular cylinder is configured with a plurality of cathode units. The outer roller of hollow circular cylindrical shape is formed by an anode substrate. The inner diameter of the outer roller is greater than that of the inner roller such that the inner roller is snugly fitted inside the outer roller. The anode substrate includes a plurality of anode units corresponding to the cathode units. The photoelectric conversion layer is a hollow circular cylinder with an inner diameter greater than the outer diameter of the outer roller such that photoelectric conversion layer is snugly fitted onto the surface of the outer roller. An electric potential difference is applied on the cathode substrate to induce the electron beam generated by the cathode unit to impinge on the anode unit to produce light. The generated light is directly converted into electrostatic by the photoelectric conversion layer to adsorb on the surface thereof to adsorb toner powder. The toner on the surface of the photosensitive drum is then transferred and fused on paper to form image.

Several ways are proposed to protect a field emission illumination device of a printer light source device. A two-terminal field emission light source structure makes use of carbon nanotubes as an electron emitter to be used as an exposure light source component of an optical printer head. The printer light source device has a low manufacturing cost, and can be matched with a photosensitive drum structure. The printer light source device is characterized by a casing coating and a light guide device to realize a light source of low cost and high efficiency.

The present invention relates to a shoe midsole structure and a method for manufacturing the same. The shoe midsole has unique hollow particle units that may be additively manufactured without any support structure. Each of the hollow particle units has a specific thickness and a hollow interior. A housing layer of each of the hollow particle units has a plurality of openings, a plurality of planar annular portions surrounding each of the openings, and a plurality of curved portions connecting adjacent planar annular portions. The plurality of openings are disposed in pair on the housing layer symmetrically with respect to the geometric centroid of the hollow particle units. A plurality of hollow particle units are arranged into a multi-laminate structure in the shoe midsole. Some hollow particle units are bent when a compression force or a shearing force is applied during use.

An X-ray machine being able to irradiate a narrowed portion within a maximum irradiation range through a control to the electrodes of an X-ray generator is provided. The X-ray machine includes a controllable X-ray generator, a digital camera and a control unit. The digital camera produces a digital visible-light image the same as the maximum irradiation range of the X-ray generator. A narrowed image portion within the digital image can be selected by the control unit. The control unit generates control signals corresponding to the selected image portion. The X-ray generator emits X-rays onto an object portion corresponding to the selected image portion based on the control signals.
