Publication number: 20140286475Abstract: An interferometer includes a diffraction grating that forms a first pattern by diffracting X-rays; a shield grating that forms a second pattern by blocking one or more of the X-rays forming the first pattern; a detector that detects information on the second pattern by detecting X-rays from the shield grating; and a scanning unit that shifts relative positions of an object and a measurable range. In the interferometer, the detector acquires a first detection result by performing a detection while the measurable range and the object take first relative positions and acquires a second detection result by performing a detection while the measurable range and the object take second relative positions. In the interferometer, the scanning unit shifts the relative positions of the measurable range and the object so that a pattern of the first detection result and a pattern of the second detection result pattern have continuity.Type: ApplicationFiled: June 5, 2014Publication date: September 25, 2014Inventors: Takashi Nakamura, Takeshi Kondoh

Patent number: 5942578Abstract: An energy beam curable pressure sensitive adhesive composition is disclosed which comprises at least two energy beam curable copolymers having energy beam polymerizable groups in side chains thereof. This energy beam curable pressure sensitive adhesive composition has satisfactory adhesive strength before the irradiation with energy beam and can be cured by the irradiation with energy beam to a degree such that the amount of adhesive residue remaining on an adherend after peeling is extremely small. Further, the above composition ensures excellent expansibility at the expanding step and excellent recognition at the time of pickup. Still further, the above composition exhibits high work efficiency because of very low pickup strength at the bonding step, irrespective of the execution of the expanding step.Type: GrantFiled: April 18, 1997Date of Patent: August 24, 1999Assignee: Lintec Corp.Inventors: Hayato Noguchi, Takeshi Kondoh
