Title: Tandem accelerating device
Inventor: TAKEYAMA KUNIHIKO
IPC: H05H5/06
Filed: 1989-04-17
Abstract: PURPOSE:To prevent leakage of the gas for charge conversion by heating a liquid which has low steam pressure at a room temperature, by forming the steam generated thereby in a charge conversion part, and by letting an ion beam pass through the steam. CONSTITUTION:In a liquid bath 10, a liquid 11 which has extremely low steam pressure at a room temperature is stored, and is heated by a heater 12. The liquid 11, being heated by the heater 12, is vaporized, and as the inside of a charge conversion part 2 is of high vacuum, the steam thereof is directed upward almost as indicated by arrows. The steam thus exists finally only in a space (A) surround by the arrows. There is almost no possibility of the steam passing through a beam passage 9 for the leakage in accelerating tubes 1, 4. An ion beam 6 from the accelerating tube 1 passes through the steam, whereby the ion beam is charge-converted, and is guided in the beam accelerating tube 4 which is charge-converted.

Title: Mark and method for matching and beam annealing equipment
Inventor: MASUSHIGE KUNIO
IPC: H01L21/265
Filed: 1993-03-31
Abstract: PURPOSE:To optimize positioning by applying a beam to positioning patterns on a workpiece or points in proximity thereto, and detecting the positional deviation between the positioning patterns and points irradiated with the beam. CONSTITUTION:Before regularly processing the surface of a workpiece 1, a beam is applied to positioning patterns 1P on the surface a plurality of times. The positioning patterns 1P are appropriately formed in a matching region 1X, rather than a regular processing region 1T, on the periphery of the surface. The positional deviation TLn between the positioning patterns 1P and beam- annealed lines is imaged at the several points using a video camera 7. It is then measured and computed to obtain corresponding numeric values. The angle of a mobile stage 2 is corrected to determine initial values of the stage 2 movement, and regular beam annealing is performed. This makes positioning possible based on the median of the fluctuation in beam annealing position, and reducing fraction defective.

Filed: 1991-04-26
Abstract: PURPOSE:To prevent a movable scroll member from being separated from a thrust supporting member by enlarging the tooth height of the movable scroll member and a fixed scroll member. CONSTITUTION:A movable scroll member 100 eccentrically engaged with a fixed scroll meter 101 is driven by the crank part 114 of a shaft 103 and impeded in its autorotation by an automatic regulating plate 230 so as to revolve to compress a fluid. But the moment of going to incline the movable scroll member 100 is generated by the relation between the compression reaction and the driving force, so that floating is generated at a part of a thrust supporting part 240, and contact surface pressure between the scroll members is heightened to enlarge required driving force or the like. The movable scroll member 100 is thereby pressed to a thrust supporting plate 220 by suction force and the like between a magnet 310 and a magnetic body 320. Pressing force can be generated between magnets or by a spring or the like.

Abstract: PURPOSE:To minimize the generation of an improper module due to wire disconnection and to suppress a decrease in its yield and an increase in its cost by providing a detecting mechanism composed of a spot light source and a photodetector. CONSTITUTION:Since a normal IC chip 12 has a plurality of wirings, a spot light source 4 and a photodetector 5 are integrally rotated along the outer periphery of the chip 12 in a horizontal direction, wirings 13 between the chip 12 and leads 14 are irradiated with a light from the source 4, and all the predetermined number of wirings are inspected. In this case, if there is a point in which a reflected light is not returned, a bonding head 2 is immediately stopped, and an alarm is generated. A reflected light on a gold wiring 13 is preferably stronger, the surface reflectivity of gold is largely different depending upon the wavelength of the light source. If its wavelength is 0.5mum or less, the reflectivity is 50% or less, while if it becomes 0.55mum, the reflectivity becomes 80% or more. Accordingly, the source 4 is advantageous with as longer wavelength as possible.

Abstract: PURPOSE:To produce a lead free-cutting steel at a low cost by blowing PbO powder to the molten steel in a ladle then casting the molten steel, collecting the fumes generated from the ladle and casting mold, adding a proper amt. of PbO thereto and using the same for blowing. CONSTITUTION:The PbO powder is blown together with gaseous Ar into the molten steel in the ladle 1 and the generated fumes are collected via an intake pipe 3 of a dust collecting cover 2 into a dust collector 4 in the stage of producing the lead free-cutting steel by injection. The molten steel added with the PbO powder is discharged from the nozzle in the bottom of the ladle 1 and is poured into a casting mold (not shown) where the molten steel is cooled and solidified. The fumes generated from the casting mold are collected in the stage of obtaining the lead free-cutting steel ingot in such a manner. The components sized <=1mm are separated from the collected fumes and at least the PbO is added to the separated powder dust. After the dust is adjusted to >=50% PbO component and 0.3-5.0 bulk specific gravity, the dust is blown into the ladle 1. The cost of producing the lead free-cutting steel and discarding of the Pb fumes is thus reduced by effectively utilizing the harmful Pb fumes.
