Abstract: PURPOSE:To perform the impedance matching in a very short time by applying a square wave pulse from the transmission side of a 4-wire line and adjusting a balanced circuit so that an average value of a voltage waveform which appears in the reception side is minimum. CONSTITUTION:When an unspecific two-wire line is connected to a four-wire line by a hybrid circuit to start the service, a blank time during mutual call is detected by a unit 14, and switching of switches 2 and 3 and successive switching operations of a switch 4 are started by a command based on this detection, and square wave pulses are charged successively through the switch 2, and an echo pulse is sent from a hybrid circuit 1 to a unit 16 through one of balanced circuits switched successively by the switch 4 for every charging. The pulse having a minimum average value is selected from pulses sent successively to the unit 16, and the balanced circuit which sends the minimum pulse is selected and is connected to the hybrid circuit 1 by switching, and thus, the service is performed in the state where the echo in the four-wire line is minimum.

Abstract: PURPOSE:To improve a feeling of steering of a steering wheel corresponding to a torsion torque by forming a pair of slanting surfaces in the reverse direction to each other on the outer periphery of a main drive shaft or a follower drive shaft giving elastic deformation to an elastic deformation element, so that the radius of the shaft becomes larger gradually. CONSTITUTION:An elastic member 21 is fitted on the inner periphery of a slide tube 16, an elastic deformation deformed elastically in the radial direction is formed at the opposite ends of this elastic member 21, and a pair of slanting surfaces 30 are formed in the reverse direction to each other on the outer periphery of a main drive shaft 11 or a follower drive shaft 12 so that the radius of the shaft becomes larger gradually and that they may come into contact with said elastic deformation and give elastic deformation to elastic deformation elements 20a and 20b. A relative rota tion generated between the main drive shaft 11 and the follower drive shaft 12 is transformed into the displacement in the axial direction of the slide tube 16 by a transforming mechanism, and a torsion torque is detected by a displacement detector 28. According to this constitution, hysteresis is small when the torsion torque is small, and therefore the return of a steering wheel is excellent. The hysteresis increases as the the torsion torque increases, and therefore a steering force for the steering wheel can be reduced.

Abstract: PURPOSE:To prevent generation of abnormal sounds by fixing a guide rail with two upper fastening tool and one lower, and thereby reducing half the load applied to each upper fastening tool. CONSTITUTION:With a clip 13 and bolt 14, the upperside of guide rails 4, 6 of a longitudinal member 9 are fixed to a fixing member 21 fastened to the upperside of the guide rails 4, 6 by means of welding, etc. Because two bolts 14 are used at the upperside of the guide rails 4, 6, the tensile load applied on each bolt 14 by the cage 3 or a balance weight 5 will be reduced to half. This increases the guide rail retaining force of the clip 13 to double and decreases the clip 13 moving amount to half, so that generation of abnormal sounds due to movement of fastening tool is prevented.
