Abstract: A vehicle sunroof has a tilting lid provided at a front part of an opening formed in a roof of a vehicle. The tilting lid is adapted to be moved vertically at a rear end thereof with lifter mechanisms. A sliding lid is provided at a rear part of the opening supported by sliders adapted to be moved along guide rails disposed on both side edge portions of the opening and is constructed so as to be moved longitudinally through such movements of the sliders. The lifter mechanisms are provided in such a manner as to be oriented laterally at portions facing a rear end of the tilting lid on a laterally oriented cross member disposed so as to extend between front end portions of the left and right guide rails.

Abstract: A document feeder is formed of a reading section for reading an original document while the original document is being transferred; a transfer roller having a transfer path therearound with an inlet located near the reading section and an exit so that the original document is transferred from the inlet to the exit through the reading section; and first and second rollers pressed against the transfer roller. The first and second rollers are located respectively in upstream and down stream sides of the transfer path relative to the reading section. A guide member is overlapped with the transfer roller at one end so that the original document from the second roller is guided from the one end to the other end.

Abstract: A document feeder of the invention is formed of a platen for reading and scanning original documents, a document tray for placing the original documents to be processed situated above the platen, and an ejection tray for receiving the original documents after being processed situated between the platen and the document tray spaced apart from each other in a vertical direction. A transfer path is formed for transferring the original documents from the document tray to the ejection tray through a reading position on the platen. An exit of the document tray, an entrance of the ejection tray and the reading position on the platen are arranged laterally in this order above the platen with a predetermined distance spaced apart from each other. A separating portion for separating the original documents one by one is situated between the exit of the document tray and the entrance of the ejection tray to be laterally spaced apart from each other. The document feeder is made compact in size.

Abstract: An optical lens press-molded so that within at least the optically effective diameter thereof, the thickness thereof may become greater from the center of the optical axis thereof toward the marginal portion of the lens, characterized in that at least one of the both lens surfaces thereof is a spherical or aspherical concave lens continuous from a transferred surface formed so that in the area outside the optically effective diameter thereof, the thickness of the lens may be limited away from the extension of a curved surface of a radius of curvature setting the optically effective diameter toward the outer diameter of the lens, and forming the transferred surface up to at least the required outer diameter of the lens, and a free surface portion is left outside the outer diameter of the lens during molding.

Abstract: A document feeder is formed of a reading section for scanning an original document while the original document is being transferred at a predetermined speed; a feeding stacker for supplying the original document to the reading section; a transfer roller having a transfer path therearound for guiding the original document transferred from the feeding stacker to the reading section; and first and second rollers located respectively in upstream and down stream sides of the transfer path for transferring the original document. A sensing device is located in the transfer path between the first and second rollers for detecting a front edge of the original document. A driving device is connected to the transfer roller to control a rotational speed of the transfer roller based on a detecting signal of the sensing device.

Abstract: There is provided a transfer path for receiving a document fed, sheet by sheet, from a document placing device, and for leading the document toward a document reading portion for reading the document placed on a stationary platen of an image forming device. In a space between the document reading portion and the document placing device disposed above the document reading portion, there is provided a switchback path for leading the document ejected from the transfer path toward an inlet side of the transfer path by a switchback-transfer. Therefore, a structure of the image forming device can be compact, front and back surfaces of the document can be automatically reversed, and an image on the document can be read while the document is being transferred.

Abstract: A compact automatic document feeder having a document storage portion including a document tray for placing thereon given original documents to be fed into an image processing device such as a copying machine, and a document receiving device disposed on the document tray. The document receiving device comprises document holding members movable widthwise for holding the document to be fed into the image processing device, and document supporting members for receiving the document discharged from the image processing device is adapted to effectively divide the document stacked on the document tray and the discharged document independently, so as to prevent the document being discharged from colliding with the document left on the document tray.

Abstract: A method for press-forming a glass preform includes the steps of applying positioning pressure to an upper mold as the temperature of the upper mold and a lower mold increase to set values, maintaining a first temperature difference between the upper and lower molds of at least 10.degree. C. and increasing the temperature of the glass preform to a value above its glass transition temperature. Additional steps include cooling the upper and lower molds at a rate of 30.degree. to 100.degree. C. per minute while maintaining a temperature difference between the upper and lower molds at at least the first temperature difference, applying pressure to the lower mold, and opening the upper and lower molds to release the formed optical element after the temperatures of the upper and lower molds decrease to below a set value and a temperature difference between the upper and lower molds becomes greater than the first temperature difference.

Abstract: A method of molding an optical element by pressing glass material uses a cavity composed of a pair of mold members and a side mold member. Either or both of the pair of mold members are rendered slidable along the axial direction of the optical element within the side mold member used during the pressurized molding operation, so that the pair of mold members move in close contact with the contracting glass along the axial direction in the side mold member, during the cooling subsequent to the pressurized molding due to adhesion between the contracting glass and either or both of the pair of mold members. The contraction of the glass during the cooling phase is limited by the adhesive force between the glass and the mold members when at least one of the pair of mold members traverses a gap and reaches a limit of travel; thus tension will be created in the glass.

Abstract: In a process for manufacturing an optical element, in which a molding material is put in molds and is heated and press-molded to manufacture an optical element, a preheating treatment of the molding material is performed before it is put in the molds at a reduced pressure and a temperature lower than a temperature during the press molding.
