Title: Forming method for color filter
Inventor: ONO ICHIRO
IPC: G02B5/20
Filed: 1987-12-25
Abstract: PURPOSE:To form the color filter by a continuous pattern by forming simultaneously layers to be dyed of color filters of each color and dyeing partially these layers to be dyed to each color. CONSTITUTION:Layers to be dyed 11 of color filters R, G and B of each color are formed simultaneously on the whole filter forming area of the surface of a substrate 2, so that these layers to be dyed 11 are dyed to each color of red, green and blue partially by forming first and second resist layers 12, 13 and its peeling-off. Accordingly, the color filters R, G and B of red, green and blue which are arranged and formed alternately on the substrate surface can be formed easily by a small number of processes. In such a way, waste of a resin to be dyed can be reduced, and also, the color filters R, G and B of each color can be formed by a continuous pattern being free from an overlap and a gap.

Title: Recovery of scaly graphite contained in dust of steel production
Inventor: KADOTO MITSUO
IPC: C01B31/04
Filed: 1987-12-25
Abstract: PURPOSE:To recover scaly graphite with high efficiency by subjecting collected dust to air elutriation, screening, and air elutriation again. CONSTITUTION:Collected dust of steel production charged from a feeding port 3 of an air elutriation apparatus to a feed pipe 2 of the dust is sucked through a filter 5 with a fan 4 and air-elutriated utilizing the difference of settling velocity and inertia of the particles of the dust in the air depending on the size and shape of the particles, and classified to easily scattered dust B (exhausted from No.8-10 chute), hardly scattered dust A (exhausted from No.1 chute), and intermediate dust C. Only, dust B and A having high vein graphite content are recovered. The amt. of the recovered dust amounts to about 1/3 of the total dust, resulting very high efficiency. Since impurities such as slag deposit frequently to scaly graphite in the dust A, the dust A is crushed to <1mm grain size, then classified to several stages together with the dust B to make the range of the grain size distribution nallower in order to separate said impurities. Each screened dust is air-elutriated again for each fraction, and classified to easily scattered dust B and hardly scattered dust A1.

Title: Precious metal and surface hardened ornament made of its alloy
Inventor: SUGIHARA TADASHI
IPC: A44C5/00
Filed: 1989-12-18
Abstract: PURPOSE:To make it difficult to have flaws without damaging metallic color on a base surface and to maintain value of beauty for a long period by forming an ion implantation hardened layer on the base surface of a precious metal and the surface of its alloy. CONSTITUTION:A precious metal and an ornament made of its alloy has its surface portion on which an ion-implantation layer with an average desirable thickness of 0.01 to 10mum is formed. The average thickness is 0.01 to 10mum because a desired surface hardening cannot be achieved when the thickness is less than 0.01mum, and in contrast, when it is more than 10mum, the surface hardening is saturated and higher hardness cannot be obtained. The thickness of the hardened layer can be freely adjusted by controlling ion-implantation energy.

Title: Deflection electromagnet for particle accelerator
Inventor: TANABE YOSHIO
IPC: G21K1/093
Filed: 1991-12-12
Abstract: PURPOSE:To provide a compact, low-cost deflection electromagnet in which saturation of an iron core is prevented while a high magnetic field can be generated even with a small magnetomotive force by providing an auxiliary yoke at one part of the outside of the electromagnet in addition to a center yoke. CONSTITUTION:A deflection electromagnet comprises a ferromagnetic pole 1, an exciting magnetic coil 2 wound onto the pole 1, and a yoke and an auxiliary yoke 4 which form a magnetic circuit. Thereby magnetic flux flowing through a conventional yoke 3 is divided and magnetic flux flowing through each yoke is reduced and an iron core is not saturated. Therefore, the magnetic permeability of the iron is large and the loss of exciting forces inside the iron core is small and a large magnetic field can be generated with a small magnetomotive force. A radiation takeout port 13 is provided in a position where it does not interfere with the auxiliary yoke 4 and thereby the use of radiation is not disturbed at all. The deflection radius of an electron beam can be reduced by heightening of the magnetic field and a compact, low-cost deflection electromagnet can be obtained.

The first hole 25a and the second hole 29a have such predetermined diameters as to fit and to securely hold the ends of the respective bare optical fibers respectively having the existing diameter to a joint array with each other.  The single structure of the intrinsic shape memory polymer material is first formed to the first form known as an intrinsic shape and is then swollen and partially shrunk to the second deformation. The deformation is returned to the first form by the non-mechanical stimulus of heat. As a result, the single structure products of the low cost suitable for use and mass production are obtd without using special high performance apparatuses.

Abstract: PURPOSE:To provide an electronic part which does not cause inequality in fusion or a bridge when heating cream solder applied on electrodes so as to fuse it, in a bump formation method which forms bumps on the electrodes made in matrix shape on the surface of the electronic part by screen printing means.

Title: Gas insulation switch gear
Inventor: YOSHIDA TETSUO
IPC: H01H33/66
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To attain electric field relaxation of an embedded electrode or a vacuum circuit breaker electrode, and reduce the overall shape, by disposing a plurality of the cylindrical embedded electrodes at respective corners while facing fitting part of a supporting insulator, and integrally-molding the embedded electrodes with epoxy resin. SOLUTION: Embedded electrodes 26, 27 are of cylindrical shape, which facilitate processing. By forming the embedded electrodes 26, 27 into a cylindrical shape from an oval shape, and disposing them at a corner part respectively, a sufficient insulation distance can be ensured, so that residual stress at the time of curing and shrinking of epoxy resin can be dispersed for reduction. In the case of the oval shape, the contact point of a curvature part and a linear part becomes discontinuous, so that stress may be concentrated, though, by forming it into a round as a cylindrical shape, the stress becomes uniform in an electrode surface, a high stress part is eliminated and reduced further. It is thus possible to reduce the thickness of an insulating layer from the embedded electrodes 26, 27 to the edge.

Abstract: PURPOSE:To prevent occurrence of a setting error of a changeover switch by connecting a 2nd relay between a 2nd input terminal and ground and using contacts of the 2nd relay as 1st and 2nd changeover switches. CONSTITUTION:A power supply connects to one terminal 2 at a sender side, a switch connects between the other terminal 1 and ground and when the switch is opened/closed to send a signal, the relay 11 is activated, contacts 20, 21 of the relay 11 are thrown as shown in dotted lines and the contacts are connected by a 1st current adjustment component 12. When the sender side switch is opened/closed, a current flows or does not flow to a relay 10, which is activated or released and contacts of the relay 10 are opened/closed to send/receive a signal. In this case, when the power supply connects to the terminal 2 at the sender side, the relay 11 is activated and the contacts 20, 21 are thrown automatically as shown in dotted lines. Thus, an erroneous state is not caused and damage to the power supply and components due to a large current flowing from the power supply at the sender side is avoided.
