IPC: B29C65/36
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To provide a method for easily blocking a hole opened in a resin pipe, even in medium pressure piping. SOLUTION: An opening is blocked by a blocking member 1 for the opening through bringing a pipe contact part 6 into contact with a resin pipe 11. High-frequency current is applied to a coil mounted on the pipe contact part 6 of a jig 5 under the described state to generate a high frequency electromagnetic wave. Consequently, eddy current is induced to a magnetic material provided on a blocker 1 for the opening and the magnetic material is heated, which in turn, fuses the peripheral part of the blocker 1 to the peripheral part of the opening of the resin pipe 11 and thus the opening is blocked. In this case, the leakage of gas to the outside does not occur as the jig 5 and the like are set in a sealed box 18.  After completion of the blocking process, a hook mechanism for engaging the blocker 1 with the pipe contact part 6 is disengaged by pulling up an extruding bar 7 and as a result, the jig 5 and the sealed box 18 are separated from the resin pipe 11.

IPC: H03J7/18
Filed: 1986-08-07
Abstract: PURPOSE:To obtain a control circuit which is inexpensive and small in size, and has a sufficient automatic frequency control characteristic, by detecting a pilot signal by an output signal from a low-pass filter, being a control signal of a variable gain amplifier of an automatic gain control loop consisting of a narrow-band filter, a level detector, and the low-pass filter. CONSTITUTION:In case the band width of a narrow-band filter 6 is the same or wider as or than a carrier wave-to-noise ratio, whether a pilot signal exists or not cannot be detected by a control signal of an output of the narrow-band filter 6, therefore, the band width of the narrow-band filter 6 is selected so as to become narrow enough against the carrier wave-to-noise ratio. As a result, in case of only a noise 3, and in case the pilot signal is contained, a control signal of a low-pass filter 18 is different, therefore, the pilot signal is caught even under the conditions of a level variation of the pilot signal and a low carrier wave-to-noise ratio, can be shifted to a synchronizing process of an automatic frequency control loop by controlling a sweep signal oscillator 14, and in the end, a synchronizing establishment is executed.

Abstract: PROBLEM TO BE SOLVED: To enable the integration of active regions and passive waveguide regions of a small radius of curvature by using an integral forming technique of an active layer by selective MOVPE (org. metal vapor phase growth method) by forming waveguides corresponding to a high mesa structure in the passive waveguides while the selective MOVPE is used. SOLUTION: Clad layers are embedded into the semiconductor substrate by dividing these layers to the first clad layer 5 having the refractive index larger than the refractive index of InP and the second clad layer 6 the same as the substrate 1 at the time of growing the InP embedment layers after the simultaneous growth of the lower clad layer 2, active layer 3 and upper clad layer 4 on the semiconductor substrate 1 by selective growth using the MOVPE. Then, the refractive indices of the active layer 3 which is the initially selectively grown optical waveguide layer and the first clad layer 5 grown in the second time may be made nearly the same and the guided light is confined mainly into the first clad layer 5 in the passive waveguide region.  Namely, the structure similar to the high mesa structure is obtd. and the radius of curvature may be reduced even in the curvilinear waveguide. The miniaturization of the semiconductor optical element is thus embodied.
