Title: Immersion nozzle for continuous casting device
Inventor: SATOU SHIGETOSHI
IPC: B22D11/106
Filed: 1983-06-08
Abstract: PURPOSE:To obtain a steel which is pinhole-free and contains nitrogen at a low concn. with an external insertion type nozzle which ejects an inert gas through annular porous refractories in the upper part of a nozzle body by fitting said refractories to the nozzle in a way as to avoid exposing the same to the inside surface of the nozzle. CONSTITUTION:An immersion nozzle 11 is fitted and held to the lower part of a lower nozzle 1 of a tundish, etc. An annular porous brick 13 formed of alumina is fitted to the upper part of an immersion nozzle body 12 formed of alumina-graphite apart >=5mm. from the inside surface in the upper part of the body 12 in a way as to constitute a part of the top surface (fitting surface) of the nozzle 11. A part of the brick 13 exposes from the outside circumference of the bottom surface of the nozzle 1 and the outside circumference in the lower part of the brick 13 is partly notched to form a gap between the brick and the body 12, thus constituting a pressure equalizing zone 14 enclosing a part of the outside circumference of the brick 13. When an inert gas is introduced through an introducing port 15 communicating with the same, the gas fills the zone 14 and gushes through the brick 13 toward an arrow on the fitting surface of the nozzle 11. The gas is thus ejected to the outside with almost no influence of the pressure drop on the inside surface side owing to the downflow of the molten steel and therefore the suction of air is prevented.

Filed: 1989-04-21
Abstract: PURPOSE:To increase the luminous quantity lighting an original and to realize compact equipment by forming a reflecting member of an LED array light source asymmetrically at both sides, decreasing the reflecting member close to an optical axis of an image forming optical system and increasing the side of the reflecting member remote from the optical axis. CONSTITUTION:The image of an original 5 lighted is formed on a linear image pickup device 7 with in image forming optical element 6.

On the other hand, the reflecting member 3B located remoter from the optical axis of the image forming system has a large reflecting area and the size of the reflecting member 3A is decreased to collect the luminous quantity by the decrease in the luminous quantity or over.

Title: Spectroscopic element for soft x-ray
Inventor: AKIMOTO KOICHI
IPC: G21K1/06
Filed: 1988-04-27
Abstract: PURPOSE:To obtain a highly graded resolving power, by using a two dimensional superstructure existing at a solid interface, as a grid surface to diffract a soft X-ray at a grid surface of a solid material. CONSTITUTION:For example, a 7X7 structure in which an interface of an amorphous Si and an Si (111) base plate exists, is used as a diffraction element 3 for a soft X-ray. An incident X-ray 1 is diffracted by a grid surface 4 of a two dimensional superstructure existing at an interface of the diffraction element 3, and then a diffracted X-ray 2 is irradiated from the element 3. With changing orderly an incident angle of the X-ray 1, a soft X-ray having a specific wave length can be taken out, being distinguished from the others. With the reason that a grid surface interval of a superstructure existing on a solid surface is larger than that of an usual bulk crystals, a limit wave length is much longer therefore even a soft X-ray which is a long wave X-ray, can be diffracted, too. Also, the diffraction element is basically crystal one and hence a fractuation problem of surface intervals can be neglected in comparison with the case of a multi-layers diffraction.

Title: Production of color filter
Inventor: NODA YOICHI
IPC: B32B7/02
Filed: 1986-05-02
Abstract: PURPOSE:To reduce-man-hours by simultaneously forming color filter elements and light shielding parts between the elements by using a specific mask. CONSTITUTION:The prescribed region of a photosensitive resin layer having dyeability on a substrate is selectively exposed by a glass mask and is then subjected to dyeing and reserve printing treatments, by which resin layers 1 and 5 dyed red formed. Resin layers 2 and 5 dyed green by the similar stage are formed thereon; further, resin layers 3, 5 dyes blue are formed. The light shielding parts 5 are exposed and dyed simultaneously with the color filter elements by the above-mentioned process and therefore, the need for the stage specific to the light shielding parts is eliminated and the number of stages is reduced.

Title: Ion implantation device and ion implantation method
Inventor: TAKADA KOICHI
IPC: H01L21/00
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To reduce dirts adhering to a wafer holding part and thereby improve the cooling efficiency of the wafer in an ion implantation device and an ion implantation method. SOLUTION: First, a control device 45 mounts a wafer W to the surface of a wafer holding part 28 by controlling a wafer transporting robot 44, and opens an opening-closing mechanism 11 by controlling driving motors 12a, 12b. Next, ion implantation is carried out by controlling driving motors 24, 26. Then, the opening-closing mechanism 11 is closed by controlling the driving motors 12a, 12b, and the wafer W is dismounted from each of the wafer holding parts 28 by controlling the wafer transporting robot 44. Since an ion beam IB from an ion generation part 8 is thus blocked by the open-close mechanism 11, the ion beam IB is implanted into a beam stop 20 in a target chamber 16, so that no particle is produced.

IPC: G11B20/06
Filed: 1985-05-15
Abstract: PURPOSE:To set FM signal unbalance compensation to an optimum state by switching the limiter level of a double limiter alternately with a head switching pulse. CONSTITUTION:A reproduced FM signal separated by a high pass filter 2 is supplied to the first limiter, and the level of the limiter is varied by the head switching signal applied from an external control terminal 9.

Filed: 1987-04-28
Abstract: PURPOSE:To enable necessary tension to be applied uniformly by a method in which a pair of rods are separately provided between frames, and tension members are provided in wound and pulled manner between the rods, and then the freely movable rod is forcedly pulled in the direction in which the tension members are pulled, and further after concrete has been set in the frame, it is hardened. CONSTITUTION:A rod 3 is inserted into the round hole 5 of a frame 1, and a rod 3a is loosely fitted into long holes 7 at the side of its opposite end. The rod 3a is movable freely in the longitudinal direction of the frame 1, 1a through long holes 7, 7a. In this state, a long carbon fiber 9 is wound continuously in between the rod 3 and the rod 3a, while the fiber 9 is gradually moved from the side of the frame 1 to the side of the frame 1a. The short frame members 11, 11a with the same width as that of the frames 1, 1a are provided in between the end parts in the longitudinal direction of the frames 1, 1a. The protrusion ends of the rod 3a projecting outside of the frame 1, 1a from the long holes 7, 7a are pulled in such a direction as to apply tension to the long fiber 9. Thus necessary tension is applied. Wedges 13 are inserted in the long holes 7, 7a so that the rod 3a does not return due to the tension repulsion of the fiber 9, and fix the rod 3a. Concrete is set in the frame, and it is released from the mold after hardening. Consequently, a uniform stress is applied to the tension member composed of the fiber 9, and the risk of breakage due to the concentration of stress is prevented.
