Title: Method and device for reinforcing optical fiber connection part
Inventor: YAMAUCHI RYOZO
IPC: G02B6/24
Filed: 1990-06-19
Abstract: PURPOSE:To reinforce a fusion-spliced part where glass is exposed as a result of heating and fusion splicing by connecting an optical fiber by fusion splicing and covering the fusion-spliced part with amorphous carbon. CONSTITUTION:The optical fiber 19 to be coated is set in the slit 17a of a 2nd reflecting mirror 17 and the slit 18a of a parabolic mirror 18 and coated with a cover 20, and both end parts of the optical fiber 19 are led out of the cover 20. The inside of the cover 20 is substituted with inert gas and raw material glass is admitted from an intake pipe 22; while part of the gas in the cover 20 is discharged out of a discharge tube 23 and sent to a gas processor, a carbon dioxide laser oscillator 11 is put in operation to emit laser light 12, thereby heating the surface of the optical fiber 19. The raw material gas is decomposed thermally on the heated surface of the optical fiber 19 to deposit carbon and the optical fiber 19 is moved lengthwise to form a lengthwise carbon film on the peripheral surface of the optical fiber. Consequently, the strength of the fusion-spliced part is increased to eliminate a decrease in the mechanical strength nor an increase in transmission loss.

IPC: C21D9/46
Filed: 1977-12-30
Abstract: PURPOSE:To prevent occurrence of coil break in cooling and pickling processes prior to temper rolling by taking out annealed cold rolled steel sheet coils at above 150 deg.C from an annealing furnace and giving uncoiling plastic strain. CONSTITUTION:Annealed cold rolled steel sheet coils 2 are inserted in payoff reels 5, 6. Sheets 2a leaving reels 5, 6 are connected to the rear ends of preceding sheets with connector 9, supplied to plastic strain rolling mill 10 at below 400 deg.C, and applied with a tension below 5 kg/mm<2> to be given a plastic strain below 2% due to compression or bending. The sheets then enter temper rolling mill 16 through cooler 12, pickling unit 13 and cooler 15. The time from giving the plastic strain to temper rolling is regulated according to formula I. The outside diameter of each roll of mill 10 is specified by formula II. Thus, occurrence of coil break can be prevented in the lateral direction of the sheets.

IPC: B23K26/06
Filed: 1982-09-16
Abstract: PURPOSE:To reduce working time in a working device which irradiates laser light to the surface of a rotating body and removes a part of the rotating body, by condensing the laser light to a linear shape in the focus position. CONSTITUTION:A rotating body 1 under unbalanced state is supported freely rotatably, and a pulse laser oscillator 7 is operated by means of a laser power source 6 through a mark 3 indicated on the outside peripheral surface thereof, a revolving speed detector 4 and a controller 5. The laser light 14a having the energy several times higher than the energy required for working the same is oscillated in parallel and is made incident to an optical system 15 provided to a moving base 12 which is movable in the axial direction of the body 1 by means of a motor M. The light 14a is bent at right angles by a reflection mirror 16 and enters a lens 18 after the diameter D is stopped down to (d) by a lens 17. Said light enters a lens 19 as parallel light 14b of the diameter (d) by which the light is stopped down only in the direction Y while having the same width (d) in the direction X and is condensed to the linear shape having the length (d). The removal of the body 1 in the sectional shape long in the axial direction is thus made possible by irradiation of one pulse.

Title: Vacuum cleaner
Inventor: YOSHIZAWA MICHIO
IPC: A47L13/20
Filed: 1999-04-30
Abstract: PROBLEM TO BE SOLVED: To unnecessitate carrying-around a vacuum cleaning part by constituting a vacuum cleaner of a mop-like dust collecting part for adsorbing dust and an independent main body vacuum cleaner for sucking the dust. SOLUTION: The dust collecting part 1 is moved on a floor surface by holding a handle and dust stuck to the floor surface is adsorbed and removed. The dust collecting part 1 where dust is stuck is pressurized at the sucking port 4 of the vacuum cleaning part to suck and remove stuck dust. The cleaning part is constituted of a dust sucking port 4, a filter 5, a vacuum fan 6, a motor 7 and an evacuation port 8 and is independent of the dust collecting part 1. Thus, the vacuum cleaner is in a separated state in the case of cleaning the floor surface so that it is not required to be carried around. Then cleaning is easily executed.

Title: Control device for internal combustion engine
Inventor: KONO KAZUYA
IPC: F02D45/00
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To avoid wrong diagnosis depending on fuel property and minimize degradation of exhaust gas of an internal combustion engine by compensating self-diagnosis result of exhaust gas related components, suspending self-diagnosis, or canceling the self-diagnosis result, according to state of fuel property. SOLUTION: Catalyst 16 for purifying exhaust gas and air-fuel ratio sensors 9, 10 are arranged in an exhaust gas passage 15. In correction of self-diagnosis based on fuel property judgment result, an operation state adequate to the diagnosis is judged. Then, the fuel property judgment result is checked, and when the fuel property is heavy oil, corrective value of O2 sensor output response delay is multiplied, and performance degradation judgment of the O2 sensor output response is performed. When the fuel property is not heavy oil, performance degradation is judged without correction. In addition, prohibition of self-diagnosis, correction of catalyst performance self-diagnosis, and change of self-diagnosis region can be respectively judged and processed. Thus, degradation of the exhaust gas can be minimized.

Title: Fixing roller and its production
Inventor: NAGAYAMA KATSUSHIGE
IPC: B29K27/12
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to produce a fixing roller which has a smoothes surface, is free from defects, such as wrinkles, and is producible with good dimensional accuracy and to obtain well fixed images by providing this roller with a fluororubber layer having a specific thickness and a fluororesin sleeve which is disposed thereon, is subjected to an etching treatment on its inner peripheral surface and has a specific thickness. SOLUTION: This fixing roller includes an arbor 1, the fluororubber layer 3 which is disposed directly or via a rubber elastic layer on this arbor 1 and has 10 to 200μm thickness and the fluororesin sleeve 2 which is disposed thereon, is subjected to the etching treatment on its inner peripheral surface and has 20 to 100μm thickness. If the thickness of the fluororubber layer 3 is below 10μm, the traces of polishing of the rubber elastic layer appear on the surface of the fluororesin sleeve 2 and the uniform thickness is hardly obtainable. If the thickness of the fluororesin sleeve 2 is below 20μm, problems arise at the time of manufacture of the fluororesin sleeve 2 and at the time of production of the roll. If the thickness exceeds 100μm, elasticity is poor.

Title: Thermal printer
Inventor: MATSUMOTO TOMOO
IPC: B41J29/38
Filed: 1990-06-20
Abstract: PURPOSE:To prevent a motor from rotating reversely due to the deflection of the rubber covering of a platen when it stops by providing a motor-driven platen which a thermal head contacts resiliently via a recording medium and a means for preventing the reverse rotation of the motor. CONSTITUTION:When motor 1 is rotated in a regular direction, since a driven side 5b is rotated via a gear 1b in the direction of an overrinning 52b, its rotation is possible without being subjected to the influences from a fixed driving side 5a. When the motor 1 stops, the gear 1b is rotated reversely by the restoring force of the rubber covering of a platen and, although the driven side 5b of a one-way clutch attempts to rotate in the direction of a driving means 51b, a breaking force is applied to the driven side 5b to make its rotation impossible, since the driving side 5a is fixed. Therefore, the main shaft 1a of the motor 1 is restrained from reverse rotation. Since the reverse rotation of the motor is hindered in this way, there is no possibility whatsoever of an abnormal paper feed being caused by a recording medium due to the reverse rotation of the motor taking place, for example, through 4 degrees.
