Title: Sputtering film deposition equiment, and fabrication of photomask blank using the same
Inventor: KURODA AKIO
IPC: G03F1/54
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To provide film deposition equipment causing no fluctuation in the degree of vacuum during film deposition in a film deposition chamber and also to provide a method of fabrication for photomask blanks minimal in dispersion of optical properties using the film deposition equipment. SOLUTION: Sputtering film deposition equipment 10 is provided with a cover 9 for regulation of gas passage in a film deposition chamber 2. This cover is constituted so that it covers a gas introducing hole 7 and a vacuum exhaust system 8 and has an opening above a target 5. Owing to this constitution, fluctuations in the degree of vacuum (gas pressure) in the vicinity of the target 5 in the film deposition chamber 2 can be prevented even if a tray on which a glass substrate is mounted is absent in some places. As a result, the photomask blanks fabricated by using this equipment can reduce dispersion in optical properties, such as optical concentration and reflectivity.

Title: Variable power optical system for copying
Inventor: MINEFUJI NOBUTAKA
IPC: G02B15/20
Filed: 1987-11-07
Abstract: PURPOSE:To obtain good performance in a wide variable power range by specifying the moving method of a zoom lens system consisting of 3 groups; negative, positive and negative. CONSTITUTION:The spacing between the 1st and 2nd lens groups and the spacing between the 2nd and 3rd lens groups are asymmetrically changed. For example, the 1st, 3rd lens groups I, III having symmetrically negative powers are disposed on both sides of the 2nd lens group II having a positive power at the time of unmagnification. The spacings between the 1st and 2nd lens groups and the 2nd and 3rd lens groups are asymmetrically changed and the powers are varied by moving the entire part while the specified object plane and imaging plane are maintained at the time of varying the powers. The good performance is thereby obtd. in a variable power region and a wide variable power of about 0.5X-2.0X.

Title: Rotary electric machine
Inventor: TSUJI EIJI
IPC: H02P23/07
Filed: 1989-10-31
Abstract: PURPOSE:To prevent the difference of cooling capacities required of primary and secondary sides by a method wherein the total sectional area of a secondary winding in a groove of a rotor iron core is larger than that of a primary winding in a groove of a stator iron core, in a rotary electric machine which is operated by AC excitation from the secondary side. CONSTITUTION:The total conductor sectional area of a secondary side winding is set larger than that of a primary side winding by the amount of ratio of ampere conductors. Accordingly, the current density of the secondary winding is made equal to that of the primary winding. As a result, the difference of cooling capacities required of the primary and secondary winding sides can be eliminated. In this way, a surplus cooling air amount can be suppressed, allowing efficient designing.

Filed: 1986-11-28
Abstract: PURPOSE:To omit a Baud rate setting job at the side of a peripheral input/ output device by utilizing the reception data given from a host device to obtain the transfer Baud rate of the host device. CONSTITUTION:A host device 6 receives the rise information of a peripheral input/output device via a transmission line and then transmits the prescribed specific dummy code data having such a format that is shown in a diagram to the peripheral input/output device. A reception data pulse length detecting part 8 detects the length of the space state of the dummy code data. An internal CPU 5 finds a Baud rate from said detected length value and sets the output of a Baud rate generator 2 to be outputted to a communication controller 1 via a Baud rate control register 9. Thus the Baud rate of the peripheral input/ output device is set for execution of transfer of data to the device 6.
