Filed: 1994-02-04
Abstract: PURPOSE:To output an optical signal with an optical wavelength not causing optical beat noise in a transmission band by always monitoring an optical signal after the synthesis by a photocoupler so as to control a light emitting element. CONSTITUTION:An optical signal with a luminous intensity Pa received from a port A and an optical signal with a luminous intensity Pb received from a port B are multiplexed in a photocoupler 20 and then demultiplexed and an optical signal with a luminous intensity Pc is outputted from a port C and an optical signal with a luminous intensity Pd is outputted from a port D. The optical signal outputted from the port D is received by a light receiving element 24, and filter circuits 25, 26 separates the received signal into a DC component equivalent to the optical signal intensity and a noise component. An arithmetic circuit 27 obtains a relative noise intensity based on the intensity of the separated DC component and the intensity of the noise component. When the relative noise intensity is high, the optical wavelength of a light emitting element 23 is controlled at a control circuit 28 to reduce the relative noise intensity less than the preset reference intensity so as to synthesize optical signals without generating an optical beat noise within a transmission band.

IPC: B29C57/04
Filed: 1979-02-05
Abstract: PURPOSE: To prevent a PVC pipe from buckling at a linear portion and wrinkles on the outer surface of a faucet being processed, by heating a thickened end portion of the pipe, and inserting the heated end portions of the pipe into a gap between a core and an outer mold from the front side of the core, which core and outer mold have the respective the first and the second diameter-increased, inclined, stepped portions, respectively.  
     CONSTITUTION: A gap between a core 1 and an outer mold 2 is set to a level substantially equal to the thickness W of a PVC pipe to be processed. The shape of the core 1 having the first diameter-increased, inclined, stepped portion (a), the second diameter-increased, inclined, stepped portion (b) and an intermediate portion (c) between the stepped portions (a), (b) is set in accordance with the shape of a faucet of the pipe. A thickened end portion (e) of the pipe is processed by heating the mentioned end portion so as to soften the same, and the softened, thickened end portion (e) is forcibly inserted into the gap between the core 1 and outer mold 2 while applying an impellent force to the pipe. Since the cross- sectional area of the pipe in each position on the core 1 is increased in accordance with an axial compressive force (f) applied to the pipe, the pipe end portion can be pressed into the gap between the core and outer mold without causing an empty space between the outer surface of the intermediate portion (c) and the inner surface of the outer mold.
