Title: Electron beam exposure device
Inventor: OOYA NOBUAKI
IPC: H01L21/027
Filed: 1978-06-09
Abstract: PURPOSE:To shorten the microprocess time by positioning several electron beams vertically to the scan direction and then giving scanning by the amount equivalent to several lines at one time. CONSTITUTION:Three units of electron gun 7, 8 and 9 are distributed linearly at one end of the vacuum container and vertically to the scan direction; and then cathode 10 discharging the heat electrons plus cylindrical 1st grid 11 coaxial to  cathode 10 are provided in oposition to the three electron guns. After this, cylindrical acceleration electrode 12 coaxial to grid 11 is provided oppsoing to grid 11,  and electron beams 13, 14 and 15 are converged by converging coil 16. These  electron beams are then deflected through deflecting coil 17 to scan the surface of  semiconductor wafer 1 which is sealed onto substrate electrode 18 at the other end.  As a result, the exposure time can be reduced by the amount equivalent to the  number of the beams, thus shortening the processing time.

IPC: E02D3/10
Filed: 1982-04-23
Abstract: PURPOSE:To make easier the enlargement of the diameter of a compacted sand pile by jetting a jet fluid onto the surrounding ground in the lower end portion of a hollow tube. CONSTITUTION:A hollow tube 1 is penetrated to a given depth into soft ground 23, sand 24 is supplied from a hopper 2, and then while pulling out the hollow tube 1, a compacting part 7 is vertically moved by an operation mechanism 8. Whereupon, the sand discharged from the lower end of the hollow tube 1 is compacted to form a sand pile 25 with an expanded diameter. In this case, the diameter D0 of the sand pile 25 is obtained from the amount of sand discharged correspondingly with a given pulling-out length of the tube 1 by using a sand face meter and a depth meter (not illustrated) to detect the sand face in the hollow tube 1 and the depth of the lower end of the tube 1. When the diameter of the sand pile 25 is detected to be a small one like D1, a pressure fluid is supplied from a supply tube 11 and jetted from a jet nozzle A to disturb the surrounding ground only for a limited range corresponding to a given diameter D0 to expand the diameter of the sand pile 25 to D0.

IPC: B26F3/12
Filed: 1984-04-09
Abstract: PURPOSE:To cut off a plastic fiber with high working property without adhering fiber flocks to an electrically heated metallic wire having a diameter smaller than that of the plastic fiber by heating and softening the plastic fiber by said metallic wire to cut off the fiber. CONSTITUTION:When a motor 91 is driven by a starting switch, an eccentric pin 94 is rotated in the counterclockwise direction and descended from the uppermost position, a supporting plate 95 is descended by its tare following the descent of the pin 94 and the fiber 1 is cut off by the metallic wire 25. The motor 91 is once stopped at the lowermost position of the eccentric pin 94. When the supporting plate 95 is descended with delay and actuates a limit switch, the motor 91 is driven again. Consequently, the pin 94 is ascended through a position shown by a supposed line C and pushes a rink 96 in the right direction, so that the supporting plate 95 is moved in a direction for keeping it away from a positioning direction 50 through an engaging means between a pin 95a and a long hole 96a and the rising locus of the metallic wire 25 can be separated from the cutting surface of the fiber 1.

Title: Magnetic head
Inventor: SUGIMORI MASAHIRO
IPC: G11B5/133
Filed: 1989-03-23
Abstract: PURPOSE:To keep gap width constant and to improve magnetic characteristic by interposing an Si layer between gap glass and a magnetic metallic film. CONSTITUTION:The magnetic metallic film 4 and the gap glass 5 are interposed to a gap 3 part formed between the confronting planes of an I-type ferrite core 1 and a U-type ferrite core 2. And the Si layer 7 is interposed between the magnetic metallic film 4 and the gap glass 5. At such a case, oxidation reaction occurs at an interface between the Si layer 7 and the magnetic metallic film 4 by heat generated in a bonding treatment etc., and an oxide film (SiO2) is formed in the Si layer. However, both Si and SiO are nonmagnetic materials, therefore, the gap width remains unchanged at preset width (gap glass + Si layer) even when, for example, the oxidation reaction occurs. Thereby, it is possible to keep the gap width constant, and to obtain satisfactory magnetic characteristic.
