The Protection in Japan of Inventions by Employees During the Course of Their Employment

This article will explain the principles involved in article 35 of the Patent Law of Japan, as revised in 1959, dealing with employee inventions in Japan. The history of the revisions which have produced the present article will be discussed, then an interpretation of article 35 will be made, and finally an analysis and criticism of this article through a comparison with foreign laws will be provided

Figuring and smoothing capabilities of elastic emission machining for low-thermal-expansion glass optics

The use of elastic emission machining (EEM) for fabricating optics from low-thermal-expansion glass for extreme ultraviolet (EUV) lithography is examined. EUV optics require figure accuracy and surface roughness of 0.1 nm root mean square (rms) or better. EEM using a rotating-sphere head is demonstrated to achieve this level of surface smoothness after a certain depth of removal dependent on the material being processed. In tests of continuous machining for 12 h, no increase in surface roughness is observed, demonstrating the high temporal stability of this noncontact processing method. EEM using a rotating-sphere head is thus confirmed to have sufficient figuring and smoothing capability for the fabrication of EUV optics. © 2007 American Vacuum Society.M. Kanaoka et al.
