  • Patent number: 9841670
    Abstract: Provided is a support frame for pellicles which includes an aluminum alloy-made frame body with a pellicle film bonded to a front surface of the frame body, and with a glass substrate bonded to a back surface of the frame body. A front-side recessed groove extending in a circumferential direction of the frame body is formed on the front surface of the frame body, and a front-side suction hole extending from an outer peripheral surface of the frame body to an inner surface of the front-side recessed groove is formed on the frame body.
    Type: Grant
    Filed: May 11, 2015
    Date of Patent: December 12, 2017
    Assignee: NIPPON LIGHT METAL COMPANY, LTD.

  • Patent number: 9598790
    Abstract: Provided is a pellicle frame that can prevent generation of haze and reduces a surface glittering defect under irradiation with collected light, and a method of manufacturing the same. The pellicle frame is obtained by using an aluminum frame material having a structure satisfying predetermined conditions on the circle-equivalent diameters of a Mg2Si crystallized product, an AlCuMg crystallized product, an Al—Fe-based crystallized product (AlmFe or Al7Cu2Fe), and an Al2CuMg crystallized product and on the area ratios of those crystallized products each having a circle-equivalent diameter of 1 ?m or more, and in addition, subjecting the aluminum frame material to anodic oxidation processing using an alkaline electrolytic solution containing as an electrolyte a predetermined organic acid salt.

  • Patent number: 6349397
    Abstract: The present invention provides a signal processing apparatus having at least a boundary scan chain for carrying out a boundary scan test, a CPU capable of being controlled by the boundary scan chain, a non-volatile memory for storing an operating program of the CPU and necessary data, and an input terminal for inputting data and other control signals from the outside to the boundary scan chain, a register for holding data transferred from the boundary scan chain and a memory for holding the data read from the register. During data rewriting, based on the control of the boundary scan chain, a rewriting program is input via the input terminal from a writing device to the boundary scan chain and then stored in the memory through the register, the CPU inputs rewriting data to write it into the non-volatile memory based on the control of the rewriting program stored in the memory.
