Title: Jitter elimination synchronizing equipment
Inventor: OONUMA AKIROU
IPC: H04L7/033
Filed: 1984-04-12
Abstract: PURPOSE:To obtain a timing pulse with high accuracy by controlling the count of a frequency divider in response to a phase difference between an input signal and a 1/2N frequency-division output of a stable synchronizing signal having 2N times frequency to eliminate the phase jitter. CONSTITUTION:An input signal (a) of a frequency Fi and a signal (e) of a frequency Fr are fed to a phase detector 1. An output (b) of the phase detector 1 is inputted to a period counter 4 and a counter gate 2. When the output (b) is at an Hi level, an external synchronizing signal in the frequency 2NFr passes through the counter gate 2. An output (c) of the counter gate 2 is generated in response to the phase difference between the signals (a) and (e). A clock counter 3 counts signals by 2<m> periods' share and an m-bit shift parallel output is obtained as the counter output. The output and a theoretical set value N are compared by a tri-state output comparator 6. The output of the comparator 6 is inputted to a frequency divider 7 to control the coefficient.

Title: Scale balance device for adjustable parallel ruler

Filed: 1994-03-18
Abstract: PURPOSE:To enhance a scale balance by allowing an eccentric can to slide In the direction normal to the pressing direction of a roller within a plane parallel to the drawing board surface in accordance with an inclined angle of the drawing board. CONSTITUTION:The fixation of a scale securing plate 10 to the base plate 2 is released by a lock mechanism, the scale plate 10 tends to drop along the inclined surface of the drawing plate through its freedom and the weight of the scale. As a result, gravitation is transmitted to the main shaft in the dropping direction, and a rotational torque of being changed by sin curve is generated in the main shaft supporting an eccentric can 20. In this manner, the eccentric can 20 receives a rotational torque. On the other hand, the rotational torque generated by pressing forces from the roller 36 is generated in the eccentric cam 20. The rotational torque is changed in sin curve in accordance with the rotation of the main shaft, i.e., the rotation of the eccentric can 20. Thus, the change of the rotational torque generated by gravitation In a scale securing plate 10 side undergoes a phase dislocation of 180 degree with respect to sin curve, so that the amount of both torques becomes the same to be canceled each other.

Title: Zero-point compensation circuit for torquesensor
Inventor: NAKAMOTO AKIRA
IPC: G01L3/10
Filed: 1990-03-23
Abstract: PURPOSE:To suppress the temperature coefficient of the sensitivity of the torque sensor to a small value and to improve the measurement accuracy of torque by incorporating a temperature sensing resistance for compensating the temperature characteristic of the sensitivity of the torque sensor in an excitation-side circuit. CONSTITUTION:The temperature sensing resistance 7 senses the ambient temperature of the torque sensor and the exciting current of an exciting coil 3 is varied with a constant temperature coefficient according to the sensed temperature to compensate the temperature characteristic of the sensitivity of the sensor automatically. At this time, the exciting current of the coil 3 varies with the constant temperature coefficeint, so the detection voltage of a detection coil 4 varies with a constant temperature coefficient which is equal in absolute value to the temperature coefficient, but inverted in sign. For the purpose, the values of resistances 8a and 8b which are constituted in an unbalanced state are properly selected to multiply the temperature coefficient of the detection voltage of the coil 4 by a constant coefficient. Consequently, the zero-point temperature characteristic of the sensor is compensated.
