Title: Front wheel suspension device for two wheeler
Inventor: SATO FUMIHIKO
IPC: B62K25/08
Filed: 1998-12-03
Abstract: PROBLEM TO BE SOLVED: To improve torsional rigidity by making an axially supporting structure in which a front wheel axle cannot rotate at a front wheel axle supporting part. SOLUTION: When a front wheel axle 6 has an axially supporting structure in which it cannot rotate at a front wheel axle supporting part 4, it can take various forms. For example, even with the front wheel axle supporting part having a conventional head end semi-circular cutout structure, it is possible to fit in a cutout structure by making a cross-section of the axle 6 slliptic with a straight side, to avoid rotation of the front wheel axle supporting part and to make it an integral structure. Additionally, it is also possible to apply it to a quick shaft capable of connecting and disconnecting a wheel only by putting up and down a lever, for example, using a cam beside a method to fix the axle by a fixing nut. Furthermore, it is also possible to install a cross member. In this case, it is possible to provide stronger torsional rigidity.

IPC: H04N5/445
Filed: 1989-12-27
Abstract: PURPOSE:To display the receiving state of a color television broadcast by a simple and low-priced system by providing a discrimination count means to count the continuing time of a discriminated color broadcasting system. CONSTITUTION:A color television broadcasting system discriminating means 11 to discriminate the color television broadcasting system of video signals, discrimination count means 12 and display means 15 are provided.

Title: Magnetic head
Inventor: ONISHI MASAHIRO
IPC: G11B5/60
Filed: 1989-12-28
Abstract: PURPOSE:To provide the magnetic head having high weatherability and reliability by forming slopes from the outer side part of a slider in a magnetic medium traveling direction to a part of the front core part on a sliding surface and forming these slopes in such a manner that the aperture edges of a core insertion window part appear thereon. CONSTITUTION:The slider 11 is formed with the core insertion window part 12 in the front part thereof and the front part of a front core part 13 housed in the window part 12 is exposed to the core insertion window part 12 and is fixed by a resin adhesive material, etc. The slopes 15 are formed on the circumference of the flat sliding surface 14 of the slider 11 up to the outer side faces of the slider. The slopes 15 on both sides in the magnetic medium traveling direction extend long so as to verge on the aperture edges 12a, 12b at both ends in the magnetic medium traveling direction of the core insertion window part 12. Since the aperture edges 12a, 12b of the window part exist on the slopes 15 in such a manner, the contact of the bulging part 10 of the adhesive material for fixing the core part bulging from the spacing between the window part 12 and the front core part 13 with the magnetic medium is averted and the reliability is improved.

Title: Method for hot-rolling steel
Inventor: NOMURA NOBUAKI
IPC: B21B1/22
Filed: 1992-12-24
Abstract: PURPOSE:To diminish the degradation of surface quality without increasing manufacturing cost by spraying mist water on the surface of a steel and making its circum-ference a water vapor atmosphere between mutual stages in an area where the steel is rolled in a hot state. CONSTITUTION:After defective parts of the tip and tail of a rough rolled steel strip S are cut off by a crop shear 1, the strip is transferred while spraying mist water by a mist spray header 3 on the surface of the steel strip S and continuously passes through the group 2 of finishing mills to be finished into a prescribed dimension. The mist water which reaches the surface of the steel strip is changed into water vapor at once and covers the surface. Thus, oxidation is accelerated on the surface layer of the steel strip S. Only a trace amount of water to be sprayed may be required since only the amount of water vapor enough to form an oxide film is desired and cooling effect in the steel strip S is very small. Since the generating rate of scale is large compared with the spray of water vapor, the transfer speed need not be lowered.

The relative dielectric constant of the low dielectric constant insulating film 5 is set smaller than the first interlayer insulating film 4. As a result, a large stepping gap is not formed on the interlayer insulating film, and the upper layer wiring layer of the multiwiring can be formed very easily.

Title: Production of atomized metallic powder
Inventor: AKIYAMA MAMORU
IPC: B22F9/08
Filed: 1991-12-26
Abstract: PURPOSE:To uniformalize the particle shape of the atomized metallic powder by maintaining the flow rate of the flow of the molten metal made to flow down from a tundish at a constant rate. CONSTITUTION:The weights of a ladle 1 and the tundish 2 are respectively detected by weight sensors 11, 4. The respective detected values of the weights are supplied to a ladle weight measuring instrument 15 and a tundish level controller 5. The measured value WMT of the tundish weight is calculated in the controller 5 which outputs the driving signal SD for controlling the opening degree of the nozzle 1b provided in the ladle from the deviation from the preset target value WST of the tundish weight to a nozzle driving device 6. On the other hand, the measured value WML of the ladle weight and the measured value WMT of the tundish weight are differentiated by differentiators 16, 17 to calculate a weight change rate DELTAWML, 4DELTAWMT which are then inputted to an injection rate controller 18. This controller calculates a level correction value W1 for maintaining the specified injection rate of the molten steel to a spraying tank 3 from the tundish 2. This value is inputted to the above- mentioned controller 5, by which the above-mentioned target value WST of the weight is changed.

IPC: C09J9/00
Filed: 1991-12-26
Abstract: PURPOSE:To provide a swellable adhesive comprising a non-cured adhesive and a swellable material, facilitating the simultaneous assembling of plural members, filling up clearances between the members with the swollen adhesive when the adhesive is cured, and giving a good adhesive strength when the plural members are simultaneously assembled with each other. CONSTITUTION:The swellable adhesive is produced by mixing (A) 100 pts.wt. of a liquid or viscous semi-solid non-cured adhesive (e.g. an epoxy resin, an urethane resin or their filmy or sheet-like article) with (B) 7-8 pts.wt. of a swellable material (e.g. 'EXPANCEL(R)': the powder of swellable fine particles manufactured by Japan Ferrite Co. etc.,), or by scattering or coating the component B on the surfaces of the component A. For example, when two kinds of pipes, e.g. a pipe 1 produced from a glass fiber-reinforced epoxy resin prepreg and a stainless steel pipe 2, are fit to each other and subsequently bonded, the pipes are fit to each other in the state that the adhesive 3 is coated or wound on the adhering surface of the member, and the adhesive is subsequently thermally cured to slightly swell, thereby filling up the clearances between the members with the swollen adhesive to strongly bond the pipes to each other.

Title: High frequency chalk circuit
Inventor: YAMAMOTO OSAMU
IPC: H01P3/08
Filed: 1993-12-24
Abstract: PURPOSE:To obtain a high frequency chalk circuit which is capable of miniaturizing a circuit and has sufficient high frequency blocking effect and shield effect. CONSTITUTION:A leader line 1 is the high impedance line inside a dielectric layer, and capacity lands 4 and 5 are capable of obtaining large capacitance with small area because they are provided closely to ground conductors 10 and 11 and makes up a low impedance capacitor. Because this capacitor is provided at a location apart from a signal layer LS where the leader line 1 is formed, the unnecessary electrical coupling with the signal layer LS or the circuit formed at the proximity layer is reduced. The ground conductors cover both surfaces of the dielectric layer where the capacity land and the leader line are incorporated and electromagnetically shields the circuit formed inside a dielectric from an external circuit.
