Abstract: PURPOSE:To improve the service to the subscribe and to attain accurate operation at the end of job, by providing a job end message transmitting function and a display device representing the busy state. CONSTITUTION:When a host computer completes the job, a center close instruction is set from the computer through an MODEM MOD and a data register REG. When a CPU recognizes this instruction, the CPU reads out a voice parameter for center close guide stored in a main storage memory MEM to an incoming call from a line afterward, the voice synthesizing is attained at a vocoder VOC to inform the end of job to the subscriber. The communicating state is monitored with a display EL corresponding to the call from the subscriber and when the subscribers make no call, the line is switched to an automatic guide device.

Abstract: PURPOSE:To prevent the generation of noise by forming a pair of elongated holes at a front and a rear parts in the axial direction of a pinion shaft, and providing cushioning material at the whole periphery of the elongated hole so as to ease a shock with this cushioning material even when a bearing moves in the elongated hole and collides with the end part. CONSTITUTION:A pinion shaft 5 is inserted into a gear box 1, and a pair of elongated holes 8, 9 are formed in the gear box 1, at the front and rear parts in the axial direction of the pinion shaft 5. A bearing 7 is integrated into the elongated holes 8, 9. The bearing 7 is movable in the major axis direction of the elongated holes 8, 9, and when the pinion shaft 5 is oscillated in the elongated holes 8, 9, a braking valve is switched to put a power cylinder in action. A groove 15 is formed at the whole periphery of the braking valve side elongated hole 9 between both elongated holes 8, 9, and cushioning material 16 is fitted into the groove 15. The bearing 7 therefore comes in contact with the elongated hole 9 side while compressing the cushioning material 16 by surface contact, so that the impact of contact is eased to prevent the generation of noise.
