Title: Method for connecting optical fibers with high strength
Inventor: OSAKA KEIJI
IPC: G02B6/255
Filed: 1991-02-20
Abstract: PURPOSE:To obtain a fusion spliced part having high strength without degrading initial strength by performing respective stages of removing coating layers, removing hermetic layers, cutting optical fiber glass and washing the optical fiber glass in this order, fusion splicing the optical fiber glass and reinforcing the fusion spliced part. CONSTITUTION:The coating layer 2 of the coated optical fiber 1 is scored and while the coating layer is heated by a heater 11, the hermetic layer 3 is exposed. Aerial discharge is then by using a pair of discharge electrode rods 5 and the hermetic layer 3 is removed by thermal decomposition to expose the optical fiber glass 4. The surface of the optical fiber glass 4 is then applied with an initial scratch by a scratching blade 8 and a bend is applied to the glass by a cutting pillow 9 to cut the optical fiber glass. The optical fiber glass 4 is immersed into a heated sulfuric acid 10 and ultrasonic waves are applied thereto to remove the deposits on the optical fiber glass 4 by washing. Two pieces of the optical fiber glass 4 treated in such a manner are fixed by V-grooved clamps 14 and are fusion spliced by the discharge heating by the discharge electrode rods 5. Further, a molded reinforcing layer 14 is formed to the outside shape equal to the outside shape of the coating layers of the coated optical fibers 1.

Filed: 1993-04-16
Abstract: PURPOSE:To reduce irregular combustion and prevent occurrence of irregular combustion sound by providing a stopper which prevents projection motion of a throttle valve which becomes less than the predetermined opening degree into a mixture air intake passage and allows projection retreat motion at above the predetermined opening degree. CONSTITUTION:A stopper 32 brings a locking section 44 into contact with a lower end 20e of a throttle valve 20 which is held in a valve holding hole 10, prevents projection motion of the throttle valve 20 which becomes less than the predetermined opening degree into a mixture air intake passage 6, and allows projection retreat motion at above the predetermined opening degree. When the projection motion is prevented, a needle 70 comes in and out of a nozzle hole 54 due to accelerator operation. When the projection motion is retreated, the needle 70 comes in and out of the nozzle hole 54 integrally with the throttle valve 20 due to accelerator operation. Consequently, it is possible to improve fuel consumption rate, reduce irregular combustion, and prevent occurrence of irregular combustion sound.

CONSTITUTION: A fiber optical sensor comprises a pair of plate 12 and 14 provided with a wavelike surface of tooth-like objects, facing each other while mutually deviated, and at least one plate is connected to a parameter which is to be sensed or measured. A signal optical fiber 10 is clamped between the plates 12 and 14, so when a force is applied on it by he parameter, the interval between the plates 12 and 14 changes and the fiber 10 slightly bends. A reference optical fiber is formed into loop having a set radius (r) for compensating temperature offset. A light source supplies light to the fiber 10, and an optical detecting means, in order to decide sensing parameter, receives the light and measures changes in brightness. The changes in light transmission in the reference fiber compensates temperature offset in the sensing parameter.
