The present invention involves the prescribing and/or dispensing ophthalmic lenses, such as progressive addition lenses, for a wearer. In one form of the invention lens usage information is obtained from a wearer and entered into a programmed computer. The programmed computer processes the lens usage information to provide a separate weighted lifestyle score for each of one or more respective lifestyle score categories, such that each weighted lifestyle score is a function of a predetermined relationship between the respective lifestyle score category and at least ophthalmic lens design feature. The programmed computer then selects or designs an ophthalmic lens design using one or more of the weighted lifestyle scores such that the selected or designed ophthalmic lens has at least one lens design feature which has been customised using one or more of the weighted lifestyle scores.

A ceiling fan including a motor having a rotatable rotor, a plurality of ceiling fans blades having a thickness, the blades connected to the rotor to rotate therewith and each of the ceiling fan blades comprising a thin edge along its leading edge that is thinner than the thickness of the ceiling fan blade to present less resistance and produce less turbulence and achieve high efficiencies.

The invention discloses a touch screen with infrared rays transmitted inside a screen body and a method for identifying touch points. In the touch screen, the infrared rays sent out by an infra-red emission unit ripe into the touch screen body, are totally reflected by an upper reflecting surface and a lower reflecting surface inside the touch screen body, and are transmitted into the infrared receiving unit. According to the invention, the infrared rays are transmitted inside the touch screen body by using the total reflection principle, and a touch body is enabled to be clung to the surface of the touch screen to generate touch response, so that the problem of touch floating height is solved; and since the infrared rays are transmitted inside the touch screen, the infra-red emission unit is not required to be placed on the surface of the touch screen. Therefore, an edge frame free touch screen is realized.

In a light-emitting assembly and a display apparatus having the light-emitting assembly, the light-emitting assembly includes a light guide plate, a first light-emitting module and a second light-emitting module. The light guide plate includes a first surface, a second surface facing the first surface and including a light incident portion and a light exiting portion, and a third surface connecting the first surface with the second surface and inclined toward the first surface. The first light-emitting module is on the light incident portion of the second surface and emits a first light to the light incident portion. The second light-emitting module faces the third surface and emits a second light having a wavelength different from the first light, to the third surface.

The invention provides a method for improving the deposition uniformity of thin films. The method comprises the following steps that a plurality of pieces of wafers are borne by using a wafer cassette; the wafer cassette is provided with a head part and a tail part, and the multiple pieces of wafers are arranged between the head part and the tail part of the wafer cassette; blocking and controlling sheets are arranged between the multiple pieces of wafers and the head part of the wafer cassette as well as / or the multiple pieces of wafers and the tail part of the wafer cassette; and the wafercassette bearing the wafers and the blocking and controlling sheets is placed in a reaction furnace tube and subjected to thin film deposition, wherein the blocking and controlling sheets have an uneven surface structure. According to the method for improving the deposition uniformity of the thin films, the blocking and controlling sheets with the uneven surface structure are guided in and replace even blocking and controlling sheets in the prior art, the gas adsorption capacity is improved by increasing the adsorption area of the blocking and controlling sheets, and the edge thickness of a product adjacent to the blocking and controlling sheets can be reduced effectively, thus the film thickness uniformity of a chip can be improved effectively, and a curve of the yield loss of the edge of the wafer cassette position is smoothed to improve the product yield.

An endoscope objective lens consists essentially of, in order from the object side, a negative first lens group, a stop, and a positive second lens group. At least one of the first lens group and the second lens includes only one cemented lens which is formed by a positive lens and a negative lens cemented together. The entire system includes a positive single lens. The endoscope objective lens satisfies given condition expressions relating to the focal length of the entire system, the center thickness of the positive single lens, the center thickness of the cemented lens, the distance from the most object-side lens surface to the stop, and the distance from the stop to the most image-side lens surface.

A manufacturing method of an application roller that applies a coating solution onto a surface of a substrate, wherein the application roller includes a roller body that includes a large diameter portion and small diameter portions coaxially extended from both ends of the large diameter portion, the manufacturing method includes: overlaying a resin layer on at least an outer periphery of each of the small diameter portions; forming a masking portion on the outer periphery of each of the small diameter portions by processing an outer periphery of the resin layer; and forming an application groove portion on an outer periphery of the large diameter portion.

A separating device that includes a wedge that extends between first and second plates, with at least one of the plates being supported by a support device such as a bar. The support device supports the or each plate while the device is in use so that the plate(s) are substantially prevented from bending or twisting due to the forces applied to the plate(s).

The invention discloses an optimally designed aspheric myopia lens and a preparation mold thereof. A spectacle lens body is divided into four areas, namely a central luminosity stable area with stable diopter change, an off-axis aberration correction area which adopts focal power compensation and controls an astigmatism value and an average diopter value, an astigmatism control area which reduces the astigmatism value as much as possible, and a processing control area which effectively controls stable change of rise and reduces edge thickness. The imaging quality of the aspheric myopia lens provided by the invention is superior to that of a myopia lens with the same luminosity in the prior art, and the aspheric myopia lens can improve the wearing comfort and reduce the influence that the actual wearing effect deviates from the theoretical design caused by the inclination angle of a spectacle frame, the wearing position of the frame spectacles and the bad habits of a wearer according to the use characteristics of the frame spectacles; meanwhile, the spectacle lens can be manufactured in batches through a mold, is convenient to process, reduces the cost, and is beneficial to further popularization and application of the aspherical lens.

The present invention provides a flexible substrate and a manufacturing method thereof. The flexible substrate is divided into a first organic material layer (21) and a second organic material layer (22). A coverage area of the second organic material layer (22) on a carrying plate (1) is greater than a coverage area of the first organic material layer (21) on the carrying plate (1) and a major, long edge of the second organic material layer (22) encloses a major, long edge of the first organic material layer (21) so as to help reduce the thickness of an edge of the flexible substrate and prevent etching residue at an edge, reduce the coverage area of the organic materials on the carrying plate, and reduce warpage of the flexible substrate. Further, an alignment mark (3) is formed on the second organic material layer (22) at a location between the major, long edge of the first organic material layer (21) and the major, long edge of the second organic material layer (22) to ensure alignment accuracy in subsequent processes, such as vapor deposition. Further, since there is only one layer of organic material at the site of alignment mark (3), light transmission rate is increased and the rate of successful alignment is enhanced.
