摘要： PURPOSE:To reduce the quantity of radiation exposure in inspection and adjustment by providing a driving part with a liquid-pressure driven rotary actuator which is provided on the top surface of a valve body and has an about 90 deg. operation angle. CONSTITUTION:Air pressure is applied to the rotary actuator 29 to rotate a valve shaft 19 coupled directly with an output shaft 26 against the deviation force of a spring which is applied to a joint 27, thereby rotating a ball 18 on a shaft 17. While the axis of the through hole 18a of the ball 18 is aligned with the axis of the center pipe 15 of a valve flange 16, a ball valve 11 is fully opened. When the air pressure is applied continuously, the valve 11 is held in the fully open state. Further, when the application of the air pressure to the actuator 29 is stopped to open the space where the air pressure is applied to an atmosphere, the output shaft 26 and valve shaft 19 of the actuator 29 are rotated by about 90 deg. with the spring deviation force of the spiral spring 28 which is applied to the joint 27 and the through-hole 18a of the ball 18 deviates completely from a pipe 15, so that the valve 11 is fully opened.

摘要： PURPOSE:To automate visual inspection without using a mirror rotating device by wrapping an image fiber with a flexible tube, winding a piece of spiral wire around the flexible tube, there y constituting the image fiber cable. CONSTITUTION:In a cable 11, a plurality of image fibers 12 are bundled. The image fibers 12 are wrapped with a flexible tube 13 in order to protect the image fibers 12. The image fibers are extending to a connecting metal fitting 15 through the inside of the flexible tube 13 so that the fibers are connected to an objective lens 14 at the tip of the cable. A piece of spiral wire 16 is wound around the outer surface of the flexible tube 13. When the cable 11 is inserted into a guide tube by a TIO driving device in inspecting operation, the spiral wire 16 is rubbed with the guide tube, and the cable 11 is twisted in the winding direction of the spiral wire 16.

摘要： PURPOSE: To enable the amount of sucked flow to be easily and automatically controlled by controlling suction while recognizing the condition of a floor face using a stress detecting means provided in a suction part. CONSTITUTION: A dust collector 7 has a floor face detector 11. If the floor face 27 is a carpet, a sliding element 15 supported on a spring 26 with a small modulus of elasticity is not displaced while only a sliding element 13 supported on a spring 24 with a great modulus of elasticity is displaced. If the floor face 27 is a tatami or wooden floor, etc., the sliding elements 13, 15 are both displaced. A displacement signal from the detector 11 is fed to the control device 3 of a cleaner main body 1 via a cable 43 and the control device 3 controls a turbine motor 2 to control the amount of sucked flow according to the floor face, and also controls the motor 9 when necessary to control the drive of a rotary brush 8.

摘要： PURPOSE:To properly and quickly recognize the incoming of a telephone call or visit of a visitor by sending a detection signal to a prescribed electric equipment so as to reduce the sound noise of the electric equipment in detecting a informing tone of a prescribed equipment. CONSTITUTION:When a call tone of a telephone set or an interphone is generated, it is detected by a call signal pickup 1 and an off-signal is generated from an off-signal generating circuit 3. The off-signal is modulated by a modulation circuit 5 and sent via a lighting line 7 and detected by a detection circuit 9. The detected off-signal is demodulated by a demodulation circuit 11 thereby deenergizing an AC relay circuit 13. As a result, since the supply of power from the lighting line 7 to an electric equipment 17 via an AC relay circuit 13 and an AC receptacle 15 is stopped, the operation of the electric equipment 17 is stopped and noise generated in the electric equipment 17 is stopped thereby allowing a call tone from a telephone set or an interphone to be listened to more clearly.
