摘要:
A plastic molding having high accuracy includes at least one transfer surface and at least one imperfect transfer portion having a concave or convex shape. The mold assembly includes a cavity into which molten resin is injected, a slide cavity piece which is capable of being slid at a prescribed time so that a gap is formed between the resin and the slide cavity piece, and a vent hole for supplying a compressed gas in the cavity. A method of producing the plastic molding includes the steps of heating resin to provide a molten resin, injecting the molten resin into a cavity of a molding, applying a resin-pressure to the molten resin, cooling the resin, sliding the slide cavity piece, and opening the mold assembly.

A method for manufacturing an optical element, such as a plastic lens or similar, by molding. The manufacturing method includes the steps of molding the plastic lens under a prescribed molding temperature higher than a glass transition level of the plastic material used to from the optical element. The manufacturing method also includes the step of gradually cooling the optical element by at least 5° C. with a speed which decreases by approximately 3° C. per minute. The optical element formed from a plastic material includes a substantially rectangular shape having a width, a height, and a thickness, wherein the width is greater than the height and the thickness is measured in an optical axis direction. The optical element also includes a refractive index distribution of approximately 2×10−5 at a central half section of the height. The optical element may be defined by the manufacturing method having the molding step and the gradual cooling step. The apparatus used to manufacture the optical element includes a molding device for molding the optical element under a prescribed molding temperature higher than a glass transition level of the plastic material forming the optical element and a device for gradually cooling the optical element.

摘要:
A Mixed Media Reality (MMR) system and associated techniques are disclosed. The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). The present invention provides systems, methods, and computer program products for modifying documents for shared use, and for collaborative discussion of shared documents. Captured digital images of documents or portions associated with a user are received, along with modifications to the images. Documents are recognized from the captured digital images, and the modifications to the images are applied to the documents. Alternatively, captured digital images of documents are received, and the documents are recognized along with a hotspot in the document. The user is authenticated to a website associated with the hotspot, and is provided access to an associated multimedia repository.

The MMR system provides mechanisms for forming a mixed media document that includes media of at least two types (e.g., printed paper as a first medium and digital content and/or web link as a second medium). The present invention provides a system, method, and computer program product for annotating unindexed documents. Captured digital images of unknown paper documents or portions associated with a user are received with annotations. Features are extracted from the captured digital image and are stored, along with the captured digital image and the annotations.
摘要:
A composite optical component and its manufacturing method are disclosed. A holding member or an optical functional device is subjected to elastic deformation, with both of them fixed together, and the optical functional device is subjected to plastic deformation by heating to reduce stress between two components in such a way that the holding member and optical functional device will be slide-fitted with each other; sliding resistance between the optical functional device and enclosure per “b” in longitudinal direction of the optical component will be F≦a/b×S×E; or the optical functional device and holding member will be slide-fit by formation of one integral body in the mold, thereby preventing thermal distortion and distortion of the optical functional device due to recovery of elastic deformation of a reinforcing member, with the result that manufacturing costs can be reduced while a high degree of straightness and high surface precision are maintained.
