Title: Magnetic head
Inventor: KAMISUKE SHINICHI
IPC: G11B5/23
Filed: 1983-11-24
Abstract: PURPOSE:To cause no deterioration of a magnetic characteristic when welding a glass by sticking thinly a nonmagnetic material such as alumina, silica, boron nitride, etc. to a gap constituting surface, and welding the glass through these nonmagnetic thin films. CONSTITUTION:Alumina is vapor-deposited to a part of 3 of a gap constituting surface of one set of ferrite blocks. Its thickness is about 0.1-0.2mum. Thereafter, a nickel thin film is stuck to a part of 4 as a spacer so as to become a gap length of a target. In this case, the vapor deposition is executed by using a mask so that nickel is not stuck onto other alumina thin film than the part of 4. The ferrite block to which such a processing has been executed is welded by using a glass.

Title: Solid electrolyte-type fuel cell
Inventor: IKEDA DAISUKE
IPC: H01M8/12
Filed: 1995-08-08
Abstract: PROBLEM TO BE SOLVED: To improve the strength of an electrode substrate and cell properties by making an oxidizing agent electrode comprising a layer produced from a raw material powder of lanthanum strontium manganite with rough grain size and a layer with 50μm or thinner thickness and produced from a raw material powder with a fine grain size. SOLUTION: An oxidizing agent electrode substrate is produced by forming a layer 1 from a relatively rough raw material powder having a composition, La1-x Srx MnO3 , and grain size distribution within 50μm and then forming a layer 2 with 50μm or thinner thickness from a relatively fine raw material powder having the same composition and the grain size distribution within 5μm on the layer 1 (wherein x=0.05-0.35). For example, a raw material powder to which a binder is added is used. An electrode substrate is thus made to have a double-layer structure consisting of the layer 1 formed by press-molding and firing and the layer 2 formed on the layer 1 by applying the raw material to the layer 1 and firing the material. A solid electrolyte 3, a fuel electrode 4, and interconnectors 5 are successively formed on the layer 2 to compose a fuel cell. Consequently, the sufficient strength necessary at the time of spraying the electrolyte 3 is provided together with the excellent cell properties.

Title: Wavelength multiplex optical network
Inventor: TAKAHASHI YASUSHI
IPC: H04B10/29
Filed: 1990-08-24
Abstract: PURPOSE:To realize the wavelength multiplex optical network in which an allowable transmission loss is taken large by providing a demultiplexing means, an optical receiver and a multiplexing means to the network. CONSTITUTION:An optical signal subjected to wavelength multiplex is inputted to a demultiplexer/multiplexer 2 of each node. The demultiplexer/multiplexer 2 is integration of sections 2-2-2-9 having wavelength selectivity on an optical waveguide 2-1, the left half 2-2-2-5 of the demultiplxer/multiplexer 2 act like a demultiplexer demultiplexing optical signals whose wavelengths are lambda1-lambdan and the right half 2-6-2-9 act like a demultiplexer inputting the optical signals whose wavelengths are lambda1-lambdan to the optical waveguide similarly. Since all the input of the optical signal is not distributed but each wavelength is demultiplexed, a distribution loss being a problem when the optical distributer is in use is not caused. Thus, the allowable transmission loss is increased.

Title: Axial impeller
Inventor: KOGA ATSUSHI
IPC: F04D29/38
Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To prevent a performance of an axial fan from reducing, and prevent non-repeatability of a performance by attaching a centrifugal impeller rotated together with an axial impeller so as to generate flow of a direction faced from a center of the axial impeller to an outside. SOLUTION: A centrifugal impeller 12 is attached on a surface of a disk 14 of a subsequent step of an impeller 1 for preventing a part of a fluid boosted up by a preceding step of the impeller 1 from leaking bypassing a clearance 21 between an inner cylinder 7 of a static blade part and the disk 14 of the subsequent step of the impeller 1. The centrifugal impeller 12 is attached on a suitable position of a diameter direction of a surface of the disk 14, and is positioned in the clearance 21. When the centrifugal impeller 12 is rotated together with the disk 14, flow is generated from a center (a rotary shaft side) of the disk 14 toward an outside (a moving blade side). The centrifugal impeller 12 is planed so as to equalize subsequent flow side pressure P1 of a preceding step of a static blade 3 and outlet pressure P2 of the centrifugal impeller 12 with each other.  It is thus possible to prevent a performance of an axial fan from reducing by leakage flow, and it is also possible to prevent non- repeatability of a performance.

Title: Preparation of poultice
Inventor: ASANO SHIYUUICHI
IPC: A61F7/02
Filed: 1982-12-17
Abstract: PURPOSE:To obtain a poultice gelatinizable uniformly at an arbitrary rate of crosslinking, and having excellent age stability, by crosslinking a water-soluble polymer with a complexing agent and two or more polyvalent matellic salts capable of reacting with said complexing agent and giving respective complex salts having different stability constants from each other. CONSTITUTION:A water-soluble polymer such as gelatin, polyacrylic acid PVA, gum arabic, etc. is swollen or dissolved in water (about 10-60% of the whole poultice). A polyvalent metallic salt (preferably a slightly soluble or hardly soluble salt) capable of forming a complex salt having high stability constant (pK) is added to the solution, and then the mixture is added with a complex of (a) a polyvalent metallic salt forming a complex salt having lower pK than the above salt and (b) a complexing agent (e.g. EDTA, nitrilotriacetic acid, etc.). The crosslinking reaction takes place by the free polyvalent metallic ion produced by the metallic ion exchange in the complex. The amount of the polyvalent metallic salt having high pK is 0.5-5 equivalent, especially 0.8-1.5 equivalent, and that of the salt having low pK value is 0.2-20 equivalent, especially 0.8-5 equivalent, per 1 equivalent of the complexing agent.

IPC: B63H9/06
Filed: 1985-10-07
Abstract: PURPOSE:To make sailing power maintainable without any deformation on a sail surface even at the time of a variation in a swivel boom angle due to the direction of a wind, by driving the rough winding winch installed in and around a turning center on a swivel boom, while streaching a rough wire and unfurling a jib sail. CONSTITUTION:A winding winch 4 is driven and a rough wire 1 is streached, then a rewinding winch 10 is driven, rolling a crew line 11 inside, and if a crew 13 is drawn toward a block 14, a jib sail 15 is unfurled. After that, if a motor 9 is driven as adjusted to the direction of a wind and a boom 7 is turned, the jig sail 15 alters its angle without almost deforming the form, whereby a boat is sailable with optimum conditions for wind force and a shift of wind all the time. Thus, flection of a sail rear edge point and the crew 13 attending upon a boom revolution is sharply reduced, so that an ideal sail surface is always keepable.

Title: Ink jet head
Inventor: HAMAFUKU YUKINORI
IPC: B41J2/05
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To positively control the quantity of ink droplet jetted from a nozzle by controlling the volume of a bubble in a pressure chamber. SOLUTION: Poles 33a, 33b are so provided on the upper and lower surfaces of the interior of a pressure chamber 27 as to sandwich signal electrodes 25a, 25b between the poles 33a and 33b. At the time of applying a voltage to the electrodes 25a, 25b, a control signal is sent to an induction coil 34 to generate a magnetic field 36 between the poles 33a and 33b. A magnetic force is operated perpendicularly to the flowing direction of a current flowing along a current route 30 via ink by the field 36, and the route 30 is moved. Since the range of the ink to be self-heating in response to the strength of the field 36 is increased, the volume of a generated bubble is also increased. Accordingly, a control signal (current) sent from a bubble control signal generator 35 to the coil 34 is controlled to vary the volume of the bubble in response to the control signal.  Since the quantity of the ink droplet to be jetted from a nozzle 33 is varied in response to the change of the bubble volume, the size of a dot formed on a recording sheet 29 can be arbitrarily changed according to the control signal.
