摘要:
An optical system that includes a molded optical element having a non-uniform refractive index distribution due to molding and a method of manufacturing the optical system is disclosed. Data of the non-uniformity of the refractive index distribution associated with molding of the molded optical element is acquired and used in order to determine the form of an aspheric surface of the molded optical element for correcting aberrations caused by the non-uniformity of the refractive index distribution. This data may be acquired by measuring the refractive index distribution of an optical element molded based on initial design values that are based on assuming uniformity in the refractive index distribution of the molded optical element or it may be computed based on the form of the molded optical element. The optical element may include a concave optical surface and may be a lens element that includes an aspheric surface.

A plating apparatus includes a substrate holding/rotating device that holds/rotates a substrate; and a plating liquid supplying device that supplies a plating liquid onto the substrate. The plating liquid supplying device includes a supply tank that stores the plating liquid; a discharge nozzle that discharges the plating liquid onto the substrate; and a plating liquid supplying line through which the plating liquid of the supply tank is supplied into the discharge nozzle. Further, a first heating device is provided at either one of the supply tank and the plating liquid supplying line of the plating liquid supplying device, and heats the plating liquid to a first temperature. Furthermore, a second heating device is provided at the plating liquid supplying line between the first heating device and the discharge nozzle, and heats the plating liquid to a second temperature equal to or higher than the first temperature.

An LED module includes: a package having electrodes provided on the outer surface of opposing sidewalls, and a light-emitting element connected to the electrodes and mounted on the package; a base member having a copper metal; an insulating layer stacked on the surface of the base member and having an insulating material; and a conductive wiring pattern connected to the electrodes by soldering and formed on the surface of the insulating layer. The insulating layer has a through-hole formed by removing a part of the section where the package is positioned, and a heat dissipation unit formed by soldering between the back surface of the package and the base member, which face one another with the through-hole interposed therebetween.

A plating apparatus 1 can perform plating processes by supplying plating liquids onto a surface of a substrate 2. The plating apparatus 1 includes a substrate rotating holder configured to hold and rotate the substrate 2; plating liquid supply units 29 and 30 configured to supply different kinds of plating liquids onto the surface of the substrate 2; a plating liquid drain unit 31 configured to drain out the plating liquids dispersed from the substrate 2 depending on the kinds of the plating liquids; and a controller 32 configured to control the substrate rotating holder 25, the plating liquid supply units 29 and 30, the plating liquid drain unit 31. While the substrate 2 is held and rotated, the plating processes are performed on the surface of the substrate 2 in sequence by supplying the different kinds of the plating liquids onto the surface of the substrate 2.

What is disclosed is a system and method for reconstructing a video signal such that selected signal components have been emphasized. Methods are disclosed for reducing the source video data to its independent signal components for selection. The source video is reconstructed, in a manner more fully disclosed herein, such that the selected component(s) are emphasized in the reconstructed video during video playback. The methods disclosed herein provide a solution for filtering an original video such that technicians can use the reconstructed video to visually examine, for instance, a dominant region of a patient's vital signals. The teachings hereof find their uses in a wide array of remote sensing applications and, in particular, the telemedicine arts.
