Title: Method for electron beam lithography
Inventor: KURIYAMA YOICHI
IPC: G03F7/20
Filed: 1992-10-28
Abstract: PURPOSE:To make it possible to find a dose required for proximity effect correction without degrading the regularity of a drawing pattern by dividing the drawing pattern into a plurality of drawing patterns according to a preset drawing pattern division size and calculating the dose for each divided pattern. CONSTITUTION:When the width w and height h of a drawing pattern 1 are three or more times a drawing pattern division size delta, the pattern 1 is divided into nine drawing patterns 5. The stored energy E(r) given, by an electron beam applied to a point in a drawing pattern, to a measuring point a distance r away from the point of the application is expressed by the formula, where betaf = forward scattering coefficient, betab = backward scattering coefficient, and eta = ratio of the magnitude of forward scattering energy to that of backward scattering energy. The irradiation offset in a irradiation offset calculation region is obtained by summing the stored energy from all the drawing patterns. This makes it possible to calculate the appropriate dose without degrading the regularity of drawing patterns.

Title: Sputtering device
Inventor: KATSURA TOSHIHIKO
IPC: C23C14/35
Filed: 1987-12-09
Abstract: PURPOSE:To obtain the subject sputtering device capable of preventing the deviation in the expansion and contraction between a sputtered film forming part and a sputtered film and capable of controlling the cracking of the sputtered film by providing a control means for controlling the temp. of the film forming part other than a substrate in the vicinity of the temp. which the part assumes and at which the part is stabilized. CONSTITUTION:The surfaces of a deposition preventing plate 15 and a substrate holder 18 are heated and kept at approximate 200 deg.C, and an SiO2 film is formed on the substrate 19 by sputtering by using a target 16 of high-purity quartz. In this case, heaters 21 and 22 are turned off when the sputtering discharge is generated to form a film, and the temp. in the vicinity is kept by the heat of the discharge. Meanwhile, the heaters 21 and 22 are turned on when the sputtering discharge is stopped, and the plate 15 and the holder 18 are kept, for example, at 200 deg.C. As a result, since the plate 15 and the holder 18 are kept at a constant temp., an increase in the number of particles formed by the cracking of the sputtered film material can be prevented even if there is a difference in the expansion and contraction due to the temp. difference between the material and the built-up film.

IPC: B05B15/04
Filed: 1992-11-20
Abstract: PURPOSE:To robotize and automatize the operations to stick tapes to large-sized parts which have heretofore been manually carried out so that the tapes can be stuck exactly and uniformly to these parts by determining the reference position of masking by measurement with a camera, then executing masking in accordance with this reference position. CONSTITUTION:While c1 is the window center on a drawing, the actual center c2 exists in a position deviating from c1. The position on the outer peripheral ridge line of a window frame 22 is, thereupon, previously determined as a measurement position and is measured by the camera for measurement. This position is subjected to image processing, by which the positions of a1, a2, b1, b2, c1, c2 on the top, bottom, right and left of the ridge lines are determined. The deviation quantity DELTAx in the lateral direction of c1 and c2 is determined by subjecting the distances x1, x2, x3, x4 between the reference line k1 in the lateral direction and the measurement points a1, a2, a3, a4 of the window frame 22 to average value processing. The deviation quantity DELTAz of c1 and c2 is obtd. in the same manner. The actual center c2 is thus determined and corrected and the working robot is actuated by which the positional deviation between the mounting position size of the window and the working position is corrected and the sticking of the tapes is thus executed.

Title: Seat for automobile
Inventor: FUKATSU YOSHIMI
IPC: A47C1/026
Filed: 1990-11-19
Abstract: PURPOSE:To make a seat back unable to perform a forward inclination operation, and prevent the intervention of a headrest with a roof trim by invalidating an operation section with an operation section control mechanism, when the seat back is inclined back over the predetermined range. CONSTITUTION:A seat back 5 is inclined back to the predetermined range by turning a wheel 41 clockwise or counterclockwise. In this case, when the seat back 5 is within the predetermined range D, an operation wire 25 is kept under tension with an operation section control mechanism 31. As a result, a pawl 17 is kept at an engagement-free position, when an operation section 23 is moved up in an arrow direction. It follows, therefore, that forward inclined state C can be obtained, when the seat back 5 is turned. On the other hand, when the seat back 5 is inclined back over the predetermined range D, the slide element 37 of the operation section control mechanism 31 moves to the lowest position of a guide groove 37a, thereby releasing the tension of the operation wire 25. According to the aforesaid construction, the operation section 23, even when moved in the arrow direction, becomes invalid, and a base plate 9 remains restricted, thereby making it impossible to obtain the forward inclined state of the seat back 5.

Title: Manufacture of ingot of metal or alloy
Inventor: WATANABE YASUSHI
IPC: C22B9/16
Filed: 1986-12-27
Abstract: PURPOSE:To manufacture an ingot reduced in grain boundaries in high yield, by allowing a powder of metal or alloy to fall, by passing the above powder through a heating zone to melt the powder, and by pulling a solid ingot while feeding the resulting melt onto an ingot whose upper part is in a melt condition. CONSTITUTION:In a heating furnace 1 equipped with heat insulating materials 8, a powder of metal or alloy of one or more materials is allowed to fall from a powder feed hopper 2, which is passed through the heating zone formed by means of a plasma generator 7 to undergo melting. The resulting melt is dropped on a pedestal 5 of an ingot pulling down device 3 to grow an solid- phase ingot 9 by means of a seed crystal 4. While this pedestal 5 is pulled down via a pulling-down rod 6, the above melt is continuously allowed to fall and fed onto a liquid-phase ingot 10 on the solid-phase ingot 9. In this way, the sound ingot of metal or alloy minimal in grain boundaries can be obtained.

Title: Automatic extruder t-die
Inventor: IGUCHI KATSUHIRO
IPC: B29C48/08
Filed: 1987-12-11
Abstract: PURPOSE:To make it possible to control the flow rate of molten resin over a wide range with good response and, when necessary, precisely locally by a constitution wherein die bolts, each of which controls the gap of a slit by displacing a flexible lip part, are made into differential type thermal displacement mechanisms. CONSTITUTION:When a heater 22 is energized or deenergized, the first temperature rise occurs in a unit main body in case of energizing, while the first temperature fall occurs in a die bolt 26 in case of deenergizing. As a result, the die bolt 26 apparently contracts and elongates with respect to the pressing projected part 56 of a flexible lip 12. Accordingly, the gap of an extrusion slit 18 is increased or reduced by means of the heating or cooling of a differential type thermal displacement unit 50. On the other hand, since the flexible lip 12 is heated through the die bolt at said heating, the temperature of molten resin flowing through the extrusion slit 18 is raised or lowered through the heating or cooling of the differential type thermal displacement unit 50, resulting in lowering or raising the viscosity of the molten resin.
