IPC: C03B37/12
Filed: 1982-08-07
Abstract: PURPOSE:To prepare optical fiber having extremely improved radiation resistance, and extremely reduced optical loss caused by exposure to radiation, by executing the prevention of generation or reduction of strain in core and clad resulting from the spinning of the parent material of optical fiber. CONSTITUTION:In preparing optical fiber by spinning the parent material of optical fiber, the prevention of generation and/or reduction of strain in core and clad caused during the drawing of the optical fiber or resulting from the drawing after the drawing is executed. For example, a dropping ratio of each drawing, shown by the formula, is set low, and multi-stage drawing is carried out. The dropping ratio was about 1/200-1/100 in the existing process, but it is about 1/100-1/10 in this process. The prepared optical fiber is annealed after drawing. The radiation resistance is extremely improved, the light loss caused by exposure to radiation is extremely reduced, optical fiber can be applied to fields having danger of exposure to radiation, such as nuclear reactors, etc., and the use range of optical fiber is enlarged.

Title: Optical fiber built-in hose
Inventor: HATTORI KAZUHIRO
IPC: F16L11/127
Filed: 1989-05-31
Abstract: PURPOSE:To eliminate turbulence of an optical signal and damage of an optical fiber by inserting the optical fiber, without being fixed, in a protecting pipe, fixedly embedded in a lengthwise direction in the interior of a hose, and helically winding around the optical fiber, exposed in both end parts of the hose, to be surrounded by a protecting tube. CONSTITUTION:A hose 1 is formed of vulcanized rubber, plastic, etc., and a reinforced layer 3, in which a reinforcing thread or the like is stranded, can be provided in the interior of the hose. Also a protecting pipe 4 is formed of material equal to the hose, and it is preferable to provide hardness and strength possible to protect an optical fiber 5 from an external pressure. The optical fiber 5 is not integrally fixed to the hose. An outer side layer 6 in both end parts of the hose 1 is removed, and the exposed otical fiber 5 is helically wound by several times on the reinforced layer 3, then a connecting metal fixture 7 is inserted to a hose end part and fixed by a sleeve metal fixture 8. Further an exposed portion of the optical fiber 5 is coated with a protecting tube 9 of sponge or the like and fixed by fixing bands 10. Thus because extension- contraction of the optical fiber for flexing and extension-contraction of the hose is suppressed, turbulence of an optical signal and damage of the optical fiber can be prevented.

The impulse component 6a is fed to a gain conversion circuit 10, in which the component is compensated for high frequencies in the frequency region. Then an output signal from the gain conversion circuit 10 is converted into a signal on time base by an inverse DCT circuit 11. Then a synthesis circuit 14 synthesizes signals after each processing and a video signal with high resolution is obtained at an output terminal 15. The adaptive processing circuit 9 and the gain conversion circuit 10 use a prediction coefficient, a predicted value and a gain conversion ratio obtained by learning in advance.

IPC: B23F5/20
Filed: 1991-05-14
Abstract: PURPOSE:To shorten a gear cutting time for a spiral bevel type gear by performing a jump indexing for the predetermined gear generating position of a gear element. CONSTITUTION:Gear generation employs a gear generating cutter where a milling cutter 12 is caused to rotate and revolve, and a gear element 14 is caused to rotate interlocked with the revolution of the cutter 12. In this case, the cutter 12 is caused to revolve in a normal direction, according to the normal rotation of the gear element 14, thereby cutting one tooth space (tooth space shown by solid line) at the predetermined gear generating position of the element 14. Thereafter, the gear element 14 is caused to retreat from the cutter 12, and the cutter 12 is caused to revolve in a reverse direction for return to the initial position as illustrate. On the other hand, the gear element 14 is caused to rotate in a normal direction, and the next gear generating position (tooth space shown by broken line) away from the previous cutting position by a plurality of pitches is kept faced to a blade 10. This process is repeated, thereby manufacturing a spiral bevel type gear.
