Abstract: A lens edging system, including: a spectacle frame measurement device and an order-side terminal device disposed at a spectacle lens order side; and an order-receiving side controller disposed at a spectacle lens order-receiving side, wherein the order-side terminal device and the order-receiving side controller are connected to each other via a communication line, the system further including: an information memory part for storing and holding information regarding a shape of a probe in the spectacle frame measurement device as probe information; and an edging shape calculation part for performing data correction reflecting an abutting mode of the probe indicated by the probe information when lens edging shape data is created at the spectacle lens order-receiving side, wherein a suitable size correction can be performed even when a frame shape of any kind of a spectacle frame is measured by the spectacle frame measurement device by performing the data correction.

Abstract: A spectacle lens manufacturing system, wherein a relationship between a type of a spectacle frame and a framing content is converted to a matrix, includes: an information memory part to store the matrix including a size correction value for a scheduled edging shape of a lens as a numerical value in the matrix; an edging information acquisition part to acquire edging information calculated based on client side information for manufacturing a spectacle lens, including spectacle lens, prescription value, frame, and tracer information, and spectacle lens manufacturing side information, and the size correction value selected from the matrix corresponding to the framing content and the frame type as numerical values in the matrix; an edger to edge a lens based on the edging information acquired by the edging information acquisition part. Even if either one of the client and manufacturing sides performs the framing step, the spectacle lens can be manufactured.

Abstract: The invention provides an antenna apparatus including a driven element formed of a rectangular conductor, and a grounding plate which is arranged in proximity to at least one of side edges of the driven element, with a predetermined interval secured therebetween. This construction requires less mounting space, achieves wide bandwidth and low conductor loss.

Abstract: The helical antenna comprises a base body and a helically-configured conductor on a top surface of the base body, wherein base body's thickness a is given as 0.3≦a≦3 (mm); length b is given as 5≦b≦20 (mm); and relative dielectric constant &egr;r is given as 3≦&egr;r≦30, and conductor's winding number x is given as 3≦x≦16 (turns), and its resonant frequency f and conductor width w satisfy formulae (1): f=Ax+By+C (MHz) and (2): w=Dx+E (mm), where y represents base body width and A through E represent constants determined according to the base body's thickness a, length b, and relative dielectric constant &egr;r.

Abstract: It is an object of the invention to provide a meander antenna that is smaller and lighter, in which the resonance frequency easily can be tuned, as well as a method for tuning its resonance frequency. The meander antenna comprises a meandering conductor on the surface of a substrate. The meander antenna is provided with a short-circuit conductor line that forms a short-circuit between two parallel opposing lines into which the conductor is bent, or an open conductor line in which a line short-circuiting the two parallel opposing lines is open. The resonance frequency can be tuned and lowered by cutting open the short-circuit line or increased by short-circuiting the open conductor line.

Abstract: A sheet feeder for feeding mails includes a mounting table having a slanted top surface for mounting thereon a plurality of sheets in a substantially upright posture thereof, a transfer belt for transferring the sheets in the slanted posture in the direction perpendicular to the surfaces of the sheets, and a take-out section for taking out the sheets in the horizontal direction parallel to the surfaces of the sheets. A mail having an envelope and a belt wrapper covering the envelope can be taken out as it is, without pulling-off of the belt wrapper from the envelope.
