Title: Manufacture of magnetic recording medium
Inventor: YOSHIDA OSAMU
IPC: G11B5/85
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic recording medium having an excellent head touch and superior envelope characteristics by using a vacuum thin-film preparation method using a hydrocarbon having unsaturated bonds and iron or cobalt as raw materials and forming a magnetic layer consisting of the thin-film of these carbides onto a supporter. SOLUTION: A crucible 5 made of MgO is placed to the lower section of a can roll 1, iron (such as Fe having 99.95% purity) is housed in the crucible 5, and Fe is heated and vaporized by irradiating an Fe surface in the crucible 5 with electron beams, and deposited onto a base film 4 travelling on the can roll 1. When Fe is evaporated, besides, an ion gun 6 is arranged so that a vapor deposition surface is irradiated with carbon ions in the vertical direction, and the ion gun 6 is supplied with the gas of unsaturated hydrocarbon as a carbon source such as benzene gas and ethylene gas and carbon ions are generated, and the inside of a vapor deposition region is fed with carbon ions. Accordingly, a magnetic layer containing carbon while using Fe as a main body can be formed.

Title: Manufacture of light emitting tube
Inventor: ORITO HIDEMI
IPC: H01J61/32
Filed: 1989-11-01
Abstract: PURPOSE:To manufacture a narrow type light emitting tube easily without variance in shape from tube to tube by forming a constricted portion between a first and a second annular recesses while heating, softening and drawing the constricted portion between a first and second annular recesses, which annular recesses serve as a constricted part in the light emitting tube and has one wall and the other wall which slopes gradually. CONSTITUTION:While moving a movable burner 3 between a first and a second annular recesses 4, 6, a constricted portion 5 is formed by heating, softening and drawing that portion. Here, since one wall 4b of the first annular recess 4 is of a gentle slope, heating time of the gentle slop may be short. Therefore, when the constricted portion 5 between the first and second annular recesses 4, 6 is heated and processed, the wall 4a of the first annular recess 4 to form the constricted part is little heated, producing no deformation. As a result, a constricted portion 7 having a uniformly straight slope is formed.

Abstract: PURPOSE:To heat a coil quickly and uniformly by entering the coil provided with a gap between wound layers into a soaking pit and making hot gas flow freely in the gap between the wound layers. CONSTITUTION:The coil 4 made up of a rough rolled metal plate 2 is inserted into the soaking pit and heated. Projections 8 are given to this metal plate 2 to form the gap S between the wound layers when this metal is wound up round the coil 4. Then, the coil 4 is inserted into the soaking pit and hot gas G is penetrated into the gap S between the wound layers of the coil 4 and heats the coil 4. Recessed parts to form projections 8 on the surface of the metal plate 2 are equipped as constitution suitably on the peripheral surface of either the upper or the lower work roll. As a result, the coil can be heated quickly, entirely and uniformly and when the metal plate is rough-rolled by work rolls into a coil, the projections 8 can be interposed as spacers between the wound layers and the gaps can be formed easily between the wound layers.

Title: Mud removal device of downward muddy water shield excavating machine
Inventor: SAKAE TAKESHI
IPC: E21D9/06
Filed: 1994-10-25
Abstract: PURPOSE: To make it possible to enhance discharge efficiency of excavated soil by providing openings of a mud feed pipe and a mud discharge pipe in a chamber between a cutter head and a bulkhead and producing a rapid flow of muddy water and hence discharging the excavated soil with the velocity of the muddy water. CONSTITUTION: Excavated soil 31 is brought into a chamber 13 by way of a slit 12 while a cutter head 11 is driven with a cutter drive device, thereby forming a rapid flow passage between a mud feed pipe 20 and a mud discharge pipe 22 and inhibiting the muddy water flow from expanding from the mud feed pipe 20 to the mud discharge pipe 22 with a cover 21, which produces a fast flow. More specifically, the tip of the mud feed pipe 22 is bent to the mud discharge pipe 22 so as to direct the flow at the mud discharge and laid out so that it may be covered with the cover 21 like an umbrella, thereby allowing the excavated soil 31 to enter the discharge pipe more easily. Furthermore, the tip of the mud discharge pipe 22 on the mud feed side 20 is partially cut and arranged so that the muddy water flow may be directed to the inside of the mud discharge pipe 22.  A jet flow is ejected from the mud feed pipe 20, thereby reducing the amount of muddy water which is fed and discharged, the functions of the mud feed pipe 20 and the mud discharge pipe 22 are designed to be changed over by combining a plurality of valves 1 to 5 so that the muddy water may be fed and discharged reversibly.

Inventor: SHIRASAKI MASATAKA
IPC: G02B6/12
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To provide a wavelength demultiplexer having a wide band and high resolution. SOLUTION: Generally, a virtual image phase array(VIPA) 230 receives an input light having each wavelength in continuous wavelength areas, generates the multiplex interference of the input light, and generates an output light. The output light can be spatially discriminated from an output light generated from an input light with the other wavelength in the continuous wavelength areas. In this device, the VIPA 230 is combined with a demultiplexer. The VIPA 230 receives the input light, and generates a corresponding output light to be propagated from the VIPA 230. The output light includes plural wavelength components. A demultiplexer 240 demuliplexes the output light into plural separated lights corresponding to the different wavelength components in the output light. The demultiplexer 240 substantially has a distributing direction vertical to that of the VIPA 230.  Thus, the light separated by the demultiplexer 240 can be detected by a fiber 200 arranged in a grating pattern.
