Title: Radiation resistant computer device
Inventor: TAKAHASHI TOSHIO
IPC: G05B9/02
Filed: 1982-05-21
Abstract: PURPOSE:To suppress a control error down to the minimum by deciding a control variables or reference variables stored in an RAM by majority and detecting that a prescribed pit in the control variable is inverted by the penetration of radiation. CONSTITUTION:A read/write control signal SRW and an address signal Sa are applied to the RAM11 and control variables P, Q, R and reference variables XA, XB which are specified by the address signal Sa are read out successively. It rarely occurs that the critical pits Pc, Qc, Rc of the control variables P, Q, R and reference variables XA, XB are simultaneously reflected by the penetration of radiation. Therefore, the inversion of an optional pit in the critical pits of respective control variables can be detected by independently deciding the majority of these critical pits Pc, Qc, Rc which are individually stored. Consequently, these control variables can be prevented from sharp change due to the penetration of radiation and the control error can be suppressed down to the minimum.

Title: Synchrotron radiation device
Inventor: MIURA FUJIO
IPC: H05H7/14
Filed: 1989-04-05
Abstract: PURPOSE:To prevent the occurrence of any fault in storing electron beams without causing instability in particle beams traveling respectively within their respective corresponding vacuum ducts and yet without deteriorating the degree of vacuum within the vacuum ducts by mutually matching impedance induced between their respective vacuum ducts. CONSTITUTION:A partition wall 21 gastightly separates a first space 7a which causes deterioration in the degree of vacuum by allowing emitted light to illuminate an absorber 9 from a second space 7b which is in an ultrahigh vacuum condition. Since the second space 7b is kept in its ultrahigh vacuum condition by allowing a cooling means to cool a second duct 20 so that the duct 20 may adsorb gas molecules on its internal circumference plane, the internal part of a first duct 1 having a second gap opened to the second space 7b is kept in its ultrahigh vacuum condition. Since the first duct 1 also has the same shape as a duct located in a straight-line section, there is no change in impedance of each duct itself. Thus, occurrence of any fault in storing particle beams may be prevented without causing instability in both a particle beam traveling within the straight-line section and a particle beam traveling within a deflecting section.

Title: Photosensitive resin developer, developing method and production of color filter
Inventor: SAKO NAOKI
IPC: G02B5/20
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To eliminate film peeling and film residues, to enhance resolution, to widen the permissible time of development to enhance the uniformity of development and to prevent the occurrence of broad unevenness by specifying the contact angle with a photosensitive resin surface. SOLUTION: The photosensitive resin developer of >=25 to <=40 deg. in the contact angle with the photosensitive resin surface is used. More preferably, the contact angle with the photosensitive resin is >=28 to <=37 deg.. If this contact angle is too high, wettability is insufficient. If the contact angle is too low, the wettability increases so high that pattern peeling occurs. In both cases, the permissible time width for development is not sufficiently improved and the broad unevenness is not eliminated. The definition of the contact angle refers to the static contact angle of the photosensitive resin to be developed with its non-exposed surface. The measurement is executed by a method for using a commercially marketed contact angle meter, adhering a water drop of 2 mm in diameter to the non-exposed surface of the photosensitive resin, measuring the angle formed by the line connecting the end and apex of the water drop and a horizontal plane and calculating the angle by doubling the value.
