Title: Stuff synchronization multiplex converter
Inventor: TEJIMA KUNIO
IPC: H04J3/07
Filed: 1988-10-28
Abstract: PURPOSE:To eliminate the need for an excess circuit by setting a VCXO so as to be oscillated at its average control signal voltage with respect to a difference with a frequency by the stuff control at the interruption of a signal input at sender side and lowering the sensitivity to its difference frequency component. CONSTITUTION:The phase of a clock inputted with an average frequency shifted by several hundreds of ppm or above from a frequency fo with an all stuff signal is compared with the phase of a low-order group standard signal oscillated frequency (within fo+ or -10ppm) of the VCXO 7 by a phase comparator 5 of a receiver side PLL circuit at the interruption of input at the sender side. Since the resulting signal exceeds a lock range + or -100ppm of the PLL circuit, the signal is a repetitive pulse having a frequency being the difference of those of two signals and fed to a VCXO control terminal. In this case, the response characteristic with respect to a control signal frequency of the VCXO 7 is designed to be attenuated at high frequencies and when the average DC voltage is shifted by the fo oscillated control voltage of the VCXO 7, the VCXO 7 is oscillated at a low-order group standard frequency even at its free- rum state and jitter due to the fluctuation component is suppressed within the standard. Thus, no special stuff signal generation control circuit is required for the sender side.

Abstract: PURPOSE:To provide a safe and efficient drilling process which can be made by one hand, and to make a drilling tool portable by providing such an arrangement that drilling is made only by rotary motion during normal operation, and tapping is made in the rotating direction so as to continue the drilling only after a predetermined torque is obtained. CONSTITUTION:Under no load condition, the rotation of a motor 2 is transmitted to a spindle 7 by way of a gear train 3 so that a housing member 10 is rotated as one unit body, and an output shaft 9 is also rotated integrally therewith by a friction force and an oil viscosity which are produced by a vane 47 pressing the wall surface of a cylinder 11. When the load torque increases, only the housing member 10 is rotated, and when the front end face of a rotor 4 and the vane 47 come onto a seal surface, oil in the cylinder is sealed. The housing member 10 is rotated in a direction in which the volume of a high pressure chamber decreases, and the torque of the housing member 10 is applied to the vane 47 by a degree corresponding to the eccentricity thereof. Accordingly, the pressure of the high pressure chamber moves a ball 23 in a relief groove 18, and enters into a low pressure chamber. During this time, the output shaft 9 is rotated. When the rotor 43 and the vane 47 pass over the seal surface, the pressures of the low and high pressure chambers balances with each other, and corotation is effected if the torque is lower than a predetermined tapping torque, thus the tapping is repeated.
