IPC: G03F1/84
Filed: 1990-07-23
Abstract: PURPOSE:To inspect a foreign matter attached on a photomask in a short time and with high reliability by superposing the pattern of the first photomask and the pattern of the second photomask on a water and transferring them. CONSTITUTION:The first photomask (a) used for manufacturing a real device and the second photomask (b) that the opaque part 13 of a pattern area transferred on the wafer in the photomask is inverted on a transparent part 14 and the transparent part 14 is inverted on the opaque part 13 are produced. Then, in order to inspect the foreign matter attached on the first photomask (a), the pattern of the first photomask (a) and the pattern of the second photomask (b) are superposed at an identical place on the test wafer and transferred. At this time, only the foreign matter attached on one of the transparent part 14 becomes the pattern left on the wafer and a mask pattern is not formed on the wafer. Thus, the defect of the test wafer is inspected by eyes or a chip comparison type device for inspecting the defect of the wafer in a short time and with high reliability.

Abstract: PURPOSE:To obtain a degree of vacuum of 10<-10>pa or less by combining an oil diffusion pump cooled by liquid nitrogen and a sublimation pump cooled by liquid nitrogen. CONSTITUTION:An oil diffusion pump 9 with 200l-liquid nitrogen cooling trap is combined with a sublimation pump 1 which can be cooled by 800l-liquid nitrogen. An ultra- high vacuum electron radiation measuring apparatus 6 is provided with a albert electrolytic dissociation vacuum meter having the modulation electrode for measuring a degree of vacuum. The exhaustion process after this apparatus is baked for 10hr under 200 deg.C is as follow. A degree of vacuum of 10<-5>pa immediately after the baking is improved gradually as the apparatus is cooled. After 7hr, a degree of vacuum enters the order of 10<-8>pa. Here, the trap of oil diffusion pump is started to be cooled with liquid nitrogen and measurement is carried out with modulation to a vacuum meter in order to eliminate the effect of X-ray. When a degree of vacuum becomes lower than the order of 10<-> pa, the liquid nitrogen is supplied to the sublimation pump and exhaustion is strated. After about 24hr, a degree of vacuum enters the order of 10<-10>pa. When the exhaustion is further continued for several days, a degree of vacuum reaches the order of 5X10<-10>pa.

Title: Method for opening pulp fiber
Inventor: MATSUKAWA ATSUSHI
IPC: B02C13/13
Filed: 1991-07-09
Abstract: PURPOSE:To easily lower an unopen rate and to rapidly perform opening treatment by arranging a screen having a large number of rectangular transmitting holes obliquely arranged thereto along the revolving zone of a rotary hammer at a specific angle with respect to the an axial line in the peripaheral direction of the hammer and having a specific opening ratio.

When the opening ratio is 20% or less, the transmissivity of pulp is markedly lowered but opened pulp can be smoothly discharged by the obliquely arranged state of the rectangular holes, the rotation of the hammer 5 and the meeting posture of the holes to the hammer 5. Therefore, the opening ratio of the screen is lowered and the amount of unopen pulp is reduced and, at the same time, the pulp can rapidly be treated.

Abstract: PURPOSE:To prevent the transfer of the ink bonded to a feed member to a recording medium. CONSTITUTION:The contact pressure of an upper discharge roller 4d being a feed member positioned on the downstream side of a recording position to a recording medium 2 is made possible to change over and, when the recording medium 2 is stopped at the time of recording, the upper discharge roller 4d is separated from the recording medium 2 or allowed to come into contact with the recording medium 2 under low contact pressure. By this constitution, the upper discharge roller 4d coming into contact with a recording surface after recording is separated from the recording medium 2 or becomes a state being weakly in contact therewith in such a state that the recording medium 2 is stopped. Therefore, the ink bonded to the upper discharge roller 4d can be prevented from again transferring to the recording medium 2.

Abstract: PROBLEM TO BE SOLVED: To improve the shape of strip so as to smoothly use horseshoes for a race, training, etc., without hindrance. SOLUTION: A strip 11 extended in an approximately U shape comprises a double structure of a stationary plate 12 made of a metal and an earth plate 13 made of a resin. The strip 11 has a stationary face of the stationary plate 12 to be fitted to a hoof and an earth face 19 of the earth plate 13 formed approximately in parallel with the stationary face. A slit 46 capable of reducing a flexural rigidity in bending the strip 11 along the fixed face of the stationary plate 12 is formed on the inner peripheral surface 21 of the strip 11.
