Filed: 1981-10-01
Abstract: PURPOSE:To accuracy detect breakdown or fusing of optical transmission fiber by quiding the CO2 laser beam to the lens, guiding the light beam of the second light source to the fiber and then reflecting the light emitted from the incident edge surface after reflection at the inside of the beam spliter. CONSTITUTION:The CO2 laser beam 1 is converged 2 and then input to the incident edge surface 3a of the optical fiber, then output with the specified diverging angle, then converged 4 and thereby necessary energy density is obtained at the focus O. When the light beam which is different in the wavelength from the CO2 laser is input to the optical axis of fiber 3 from the light source 6 with the specified inclination, the light beam is partly emitted from the edge surface 3b and partly emitted from the incident surface end 3a after reflection. The CO2 laser beam transmits through the beam splitter 8 and only the second light beam is reflected. The reflected beam is converged 9, the detected output 10 is processed 11 and thereby an output of oscillator 1 is controlled. According to this structure, when there is a crack on the optical fiber 3, the light beam of second light source 6 is almost absorbed thereby and amount of reflected light is attenuated and therefore the oscillator 1 is stopped and an alarm 13 is issued.

Abstract: PROBLEM TO BE SOLVED: To hold a wire bar without slippage or applying a large clamping force by equipping a pressing means of a grip for gripping and holding a wire bar with a pressing group, wherein thin plate pressing pieces are laminated, and a suppressing means for energizing the pressing pieces in a pressing direction. SOLUTION: Right and left pressing means 22 are rotated around an opening 30 of a rotation axis, and displaced in a way that abutting faces 28 approach each other. A cable fed between the pressing means 22 is guided by a guide groove 32 of a guide plate 24, and placed at a given position of a tip face of a pressing group 25. When the pressing means 22 are further rotated, a convex part 37 at the tip of a pressing piece 26 is brought into contact with a peripheral wall of the cable so as to press the cable from right and left. At that time, a spring part 40 of the pressing piece 36 is elastic deformed, so as to press the peripheral wall of the cable by an elastic force.  Since the protrusion part 37 at the tip of the pressing piece 36 is displaced corresponding to the cable, the tip face of the pressing group 25 is formed into a shape along the peripheral wall of the cable so as to support the cable under a pressing condition. The tip of the pressing group 25 has the protrusion 37, so as to hold it with large coefficient of friction and without slippage.

Filed: 1980-11-08
Abstract: PURPOSE: To achieve saving of energy and to make the variation characteristics of fan voltage adjustable, by constituting a fan-speed controlling circuit such that the speed, operation and stoppage of a fan is controlled by amplifying the output of a room-temperature sensor between a maximum and a minimum set voltages and comparing the same with a reference voltage.  
     CONSTITUTION: A voltage of a thermistor 1, higher than the voltage of a minimum voltage setting circuit 12 but lower than a set voltage of a maximum voltage setting circuit 8 via an amplifying circuit 9, is applied to an input terminal B of a comparison circuit 13. Therefore, if the room temperature becomes higher than a set temperature during cooling operation, voltage at the input terminal B of the comparison circuit 13 is raised, so that a fan driving circuit 16 is ignited at an advanced phase and a fan 17 is operated at a high speed under a maximum voltage. However, when the room temperature is lowered to the set temperature, the fan is operated under a minimum voltage and it repeats operation and stoppage by the function of a stop circuit 19 within a set temperature range of the stop circuit 19. By thus controlling the fan speed, it is enabled to achieve saving of energy and to make the variation characteristics of the fan voltage adjustable.

Abstract: PURPOSE:To prevent the fluctuation of quality after curing from occurring by a method wherein a sensor mark, which is shaped at the peripheral ear part of a green plate, is detected by a sensor so as to seat only product-shaped plate parts on a seating pallet with a suction shifter. CONSTITUTION:A sensor mark 5 is produced at a peripheral ear part 3 at press molding.
