A method for managing UV irradiation for treating substrates in the course of treating multiple substrates consecutively with UV light, includes: exposing a first UV sensor to the UV light at first intervals to measure illumination intensity of the UV light so as to adjust the illumination intensity to a desired level based on the measured illumination intensity; and exposing a second UV sensor to the UV light at second intervals to measure illumination intensity of the UV light so as to calibrate the first UV sensor by equalizing the illumination intensity measured by the first UV sensor substantially with the illumination intensity measured by the second UV sensor, wherein each second interval is longer than each first interval.

A UV liquid gel solidifying device includes a support member, a UV LED module, a top cover, and a base. The UV LED module is installed on the support member and emits light into a first chamber of the support member. The support member is disposed on the base, and the base has a third chamber defined there beneath. The top cover is assembled on the support member and has a slide cover slideably mounted thereto. When the slide cover moves toward a first direction, the first open end and the second open end are opened so that the user's fingernails can be put in the first chamber for treatment. When the slide cover is released to revert back to close the first open end and the second open end, the user's eyes can avoid from being directly exposed to the UV light. When the toenails are to be treated, the base can be conveniently disassembled from the support member, and the toenails to be treated are inserted into the first chamber for treatment.

An exposure method for irradiating a mask with an illumination light through an illumination optical system and exposing photosensitive substrate to the illumination light through a projection optical system including the steps of supplying gas having less absorption of the illumination light to a light path of the illumination light, at least a portion of the illumination optical system and the projection optical system; and changing an exposing condition for the photosensitive substrate in accordance with a variation in transmittance or in reflectance of at least one of the illumination optical system and the projection optical system, resulting from irradiation of the illumination light and attenuation of the illumination light in the light path.

Introducing ultraviolet (UV) light to alter the environment inside a shoe or other footwear destroys microorganisms or inhibits their growth. Visible light can also be used to prevent further growth. Introducing forced air flow through the footwear removes dampness in and thereby deodorizes the footwear. A preferred embodiment comprises an adjustable shoe tree equipped with a UV germicidal light source and electronic safeguards that prevent appreciable leakage of UV radiation outside the shoe.

Introducing ultraviolet (UV) light to activate a photocatalytic oxidation coating applied to interior portions of footwear alters the environment inside a shoe or other footwear to destroy microorganisms or inhibit their growth. Visible light can also be used to prevent further microorganism growth. Introducing forced air flow through the footwear removes dampness in and thereby deodorizes the footwear. A preferred embodiment comprises an adjustable shoe tree equipped with a UV germicidal light source and electronic safeguards that prevent appreciable leakage of UV radiation outside the shoe.

A device that can sterilize material passing through it efficiently by utilizing an appropriate light source that can be powered by external sources (including use of an electromagnetic field to transmit energy) or by a power source that is contained within the device itself, which may include elements to create turbulence within the material passing through it, and elements to reflect the light source where useful but trap the light from escaping to ensure safety. The device may be rigid or flexible, possibly including a mechanism to fold or collapse the device for delivery through a port or lumen and expanded or unfolded prior to use.

An image forming apparatus having a photosensitive element, is provided with a light source for scanning light to the photosensitive element; a light blocking member disposed in a light traveling path of the light from the light source and moving between a blocking position where the light blocking member blocks the light scanned from the light source and a withdrawal position where the light blocking member is withdrawn from the blocking position; a power supply unit for supplying electric power to the light source for scanning light; a power switch unit for regulating power supply from the power supply unit; and an operating part locating the light blocking member at the blocking position and controlling the power switch unit to cut off the power supply in a predetermined exposure condition. As a result, a user is kept from being exposed to the light from a light source.

Photosensitive paste compositions, barrier ribs of plasma display panels (PDPs) prepared using the same, and PDPs including the barrier ribs are provided. The photosensitive paste composition includes an organic-inorganic complex sol and an inorganic material, wherein the average refractive index (N1) of the organic-inorganic complex sol and the average refractive index (N2) of the inorganic material satisfy the equation −0.2≦N1−N2≦0.2. Using the photosensitive paste composition, patterned barrier ribs for PDPs having high resolution and high precision can be made by exposure to light only once. Barrier ribs having higher reflective indices than conventional barrier ribs can also be obtained.

An image forming apparatus includes a photosensitive body, a light scanning lamp, and a lamp controller. The image forming apparatus has a surface capable of accepting an electric potential. The light scanning lamp can scan a lamp light toward the photosensitive body to change the electric potential of the photosensitive body. The lamp controller moves between a blocking position to block the lamp light from reaching the surface of the photosensitive body, and an unblocking position that is spaced from the blocking position and allows the lamp light to reach the surface of the photosensitive body.

Disclosed is a chip substrate. The chip substrate includes: conductive portions laminated in one direction to constitute the chip substrate; insulation portions alternately laminated with the conductive portions to electrically isolate the conductive portions; a cavity formed at a predetermined depth in a recessed shape in a region including the insulation portions on an upper surface of the chip substrate; and a groove portion disposed outside the cavity in a spaced-apart relationship with the cavity and formed at a predetermined depth in a recessed shape. According to the present invention, an adhesive agent is applied in a groove portion formed in advance. It is therefore possible to prevent the adhesive agent from being exposed to the light emitted from optical elements and to prevent the adhesive agent from being denatured. This makes it possible to enhance the reliability of lens bonding. Furthermore, there is no need to use an expensive resistant adhesive agent. An existing typical adhesive agent may be used as it is. This provides an effect of saving costs. Thus, there is an advantage in that a low-priced existing bonding material may be applied to a high-priced UV-C (deep-UV) package.

The object is completely irradiated from all sides by pulsed light in the second region for the sterilization.

A light-deprivation system includes shades having a fixed end that form a perimeter that defines a growing environment, cables attached to a free end of each shade, a cable guide located near a pinnacle of the light-deprivation system, and a winch to draw the shades. The cables run from the free end of each shade, through the cable guide, to the winch. Operation of the winch draws the shades simultaneously to block substantially all light from sources external to the growing environment from reaching the growing environment.
