Title: Magnetic-field applying device installed in electron microscope
Inventor: AOKI YOSHINORI
IPC: H01J37/26
Filed: 1981-07-03
Abstract: PURPOSE:To reduce the distance between a sample and an objective lens, and increase  the multiplying factor of observation carried out with an electron microscope by providing the first polarizing means between the objective lens and a means used for  applying a magnetic field along the sample surface, and the second polarizing means between a diffracted image and a transmitted image. CONSTITUTION:The second magnetic pole 9 which produces a magnetic field which  swings back electron rays, which receive a deflection angle of alpha after passing through  a sample 1, by the angle of alpha is installed between an objective lens 5 and the first magnetic pole 1 which applies a magnetic field along the surface of a sample 2. In  addition, the third magnetic pole 10 is installed in back of the objective lens 5, between a position 12 where a diffracted image is formed and a position 11 where a  transmitted image is formed. Here, the magnetic field of the pole 10 is moved perpendicularly to an optical axis 8 so that the imaging position of the transmitted image  coincides with an imaging position given when the magnetic poles 1 and 9 don't work.  As a result, the distance (a') between the sample 2 and the lens 5 can be made small,  and the observational multiplying factor can be made large.

Title: Method of manufacturing laminated board
Inventor: WATANABE SUNAO
IPC: C03C13/00
Filed: 1988-04-27
Abstract: PURPOSE:To reduce considerably the dimensional changing rate by paying attention to the percentage by weight of SiO2, Al2O3 and MgO component, and by using a glass cloth in which they are contained in a specified ratio. CONSTITUTION:The components of a glass cloth used herein are in its percentage by weight such that SiO2 is 60% or more, Al2O3 20% or more and MgO 9% or more, and the total amount of three components of these SiO2, Al2O3, MgO is 95% or more. The components of SiO2, Al2O3 and MgO are respectively more than that of E glass, and CaO occupying at 15-25% in the E glass is less extremely. Thus, the tensile strength and the tensile elastic modulus of the glass cloth is increased greater than that of the E glass. In as much as the laminated board obtained in use of the glass cloth has a strong resistance force relative to the mechanical stress and the thermal stress given in a printed circuit forming process, the dimensional change is extremely small.

Title: Method of preventing high-temperature corrosion by way of fuel treatment
Inventor: CHIKAZAKI MITSUO
IPC: F02C7/22
Filed: 1983-06-13
Abstract: PURPOSE:To prevent corrosion of members of a gas turbine subjected to high temperature, by adding the compound of an element forming a sulfate having a higher free energy of formation than the sulfate of Na to the fuel of the gas turbine. CONSTITUTION:The compound of an element forming a sulfate having a higher free energy of formation than the sulfate of Na, for instance, a compound of Ba, Mg or Ca is added to the fuel of a gas turbine. By burning such samples 1, 2 at a nozzle 3, sulfate of the added element is formed preferentially, and formation of Na sulfate is suppressed. By thus reducing formation of Na sulfate, it is enabled to prevent corrosion of the members of a gas turbine which are subjected to high temperature.

Title: Manufacture of semiconductor laser
Inventor: MORIMOTO MASAHIRO
IPC: H01S5/12
Filed: 1983-06-13
Abstract: PURPOSE:To obtain the distributed feedback type laser of a large amount of photo feedback and less threshold current by a method wherein a resonator utilizing Bragg's reflection due to periodical unevenness is formed at the interface between a waveguide layer and an enclosed layer, so that the side surface of this periodical unevenness makes an accurate perpendicular surface to the direction of photo radiation. CONSTITUTION:The laminated body of the lower waveguide layer 12 of N-InGaAsP, an active layer 13 of InGaAsP, the upper waveguide layer 14' of P-InGaAsP, and an auxiliary layer 20' of P-InP is formed on a substrate also serving as the lower enclosed layer 11 of N-InP. Successively, a resist mask 21 having a plurality of stripe apertures 21' is formed, and next stripe apertures 20' are formed by etching the auxiliary layer 20', thus forming a mask 20 to form the periodical unevennes in the layer 14' serving as the waveguide layer. Using the mask 20, new apertures 20''' are formed by etching the layer 14' to a depth approx. half, and accordingly the upper waveguide layer 14 having periodical unevenness is formed in the upper layer part. Since the side surface of the periodical aperture formed in such a manner is preserved as a plane perpendicular to the direction of photo radiation, a sufficient amount of photo feedback is secured, while the threshold current is reduced.

IPC: B22D29/00
Filed: 1984-05-23
Abstract: PURPOSE:To permit the easy sepn. of a cope and drag after solidification and to decrease the amt. of the molding sand to be carried away when a casting is taken out in the stage of casting the casting with a casting mold divided to upper and lower parts by removing partly the wall of the sprue provided to the cope so that the molten metal in the sprue flows out into the molten metal pool provided on the cope surface. CONSTITUTION:The molten metal is poured into the funnel-shaped sprue 13 provided to the cope 2 and is cast through a vertical runner 12 and a horizontal runner 11 into the pouring spaces 14 of the casting mold 1 constituted of the cope 2 and drag 3 in the stage of casting the molten metal into the spaces 14. Part of the sprue wall 15 is broken away by the cutter 29 of a device 20 for removing the wall of the sprue to admit the molten metal in the sprue 12 into the molten metal pool 19 provided atop the cope before the molten metal in the sprue 13 solidifies. The molten metal does not exist in the sprue in the stage of detaching the cope 2 from the drag 3 after the cast metal solidifies and therefore the cope 2 is easily separated from the drag 3 without collapsion. The amt. of the molding sand stuck to and carried away by the casting in the stage of taking the casting out of the drag is extremely decreased.

Title: Reel brake device and recording or reproducing device
Inventor: KOBAYASHI JUNJI
IPC: G11B15/18
Filed: 1995-04-28
Abstract: PURPOSE: To obtain strong brake force with a structure capable of reducing the cost. CONSTITUTION: A reel base 8 is so arranged that a friction member 41 is interposed between a reel mounting member 23 to be mounted with a reel and a reel base gear 31 to be rotatively driven by an idler gear 32, and the reel mounting member 23 has a cylinder part 23c and a toothed part 23d respectively on its outer circumference. A brake lever 51 has an arm part 51a to be always in press-contact with the cylinder part 23c and a pawl part 51b capable of engaging with and disengaging from the toothed part 23d, and at the time of rotating the reel base 8 in the direction of feeding a tape, the pawl part 51b is engaged with the toothed part 23d due to oscillation caused by follower action of the arm part 51a attending upon the rotation of the reel base 8.  Since parts such as a spring, etc., which are separate bodies from the brake lever 51 can be discontinued while the reel mounting member 23 is directly fixed in interlocking with the rotation of the reel base 8, strong brake force can be obtained without depending upon a torque limiter.
