Abstract: An optical lens includes an optical zone, and the optical zone includes a relax zone, a distance zone, and a defocus zone. The distance zone surrounds the relax zone. The defocus zone surrounds the distance zone and the relax zone. The diopter of the relax zone reduces along a direction from a center of the optical zone to an edge of the optical zone.

Abstract: A non-toxic water soluble photosensitive resin composition able to function as a solder mask coating comprises a polymer containing oxazolinyl, a photosensitive monomer, and a photo-initiator. These elements are all water soluble or water dispersible. The polymer containing oxazolinyl and the photosensitive monomer have a plurality of carbon-carbon double bonds. The polymer containing oxazolinyl and the photosensitive monomer are polymerized to form a dense cross-linking network structure when the water soluble photosensitive resin composition is exposed to ultraviolet radiation. A film using the water soluble photosensitive resin composition is also provided.

Abstract: A pillow with better neck support structure in accordance with the present invention comprises: a head support portion connected to a correction support portion, the head support portion is softer than the correction support portion. The user's head can be well positioned when laid on the head support portion which is softer than the correction support portion, and the correction support portion which is relatively harder can support the user's head in such a manner that the scapula of the user is supported on the second support section of the correction support portion, while the user's neck is suspended with respect to the traction section, so that the cervical spine, under its gravity, can be returned to a pressure-free and most ergonomic position, thus improving blood circulation in the brain cells.

Abstract: A slot antenna includes a dielectric substrate, and an antenna body that is formed on the dielectric substrate. The antenna body defines an open loop antenna slot that has first and second ends, and an open loop perturbation slot that extends inwardly from the open loop antenna slot, and that has first and second ends, each of which is connected to a respective one of the first and second ends of the open loop antenna slot.

Abstract: A demagnetization circuit for reducing interference in a mobile phone includes a wave filter, a demagnetization circuit and an audio playing circuit.

Abstract: The light guide plate has a flat body. At least one of the light emission plane and the light reflection plane of the light guide plate has a number of linear reflection structures arranged in parallel along the surface. The reflection structures have a V-shaped cross section pointing outward from or inward into the surface. Each reflection structure further has at least one of its end surfaces slanting towards the other end. It is the reflection structures' slant end surfaces that provide additional collimation and enhancement to the light beams traveling through the light guide plate.
