Abstract: PURPOSE:To stabilize the rotation and stopping of a sheet feed roller and an eccentric cam, and improve the accuracy thereof at a stop position by providing a hook to be engaged with the notch of a notched cam at the position where the toothless part of a gear without a tooth partially is opposite to a drive gear, and engaging the toothed part of the gear with the drive gear upon the releasing of the hook. CONSTITUTION:When a solenoid 24 is turned on and a hook 23 engaged with the notch part 20a of a notched cam 20 is released, a gear 21 having no tooth partially begins to turn on the operation of a spring member 25 and the toothless part 21a of the gear 21 is dislocated from the opposite face of a drive gear 22, thereby causing the engagement of a toothed part with the drive gear 22. Consequently, a sheet feed roller 14 is supplied with a rotational force. A solenoid 24, after the engagement of the toothed part with the drive gear 22, is turned off and the hook 23 moves down due to the own weight thereof. When a sheet feed roller 14 rotates once, the hook 23 is properly engaged with the notch part 20a. In addition, the tooth-less part 21a of the gear 21 comes to be opposite to the drive gear 22 at the aforesaid engagement position and a geared state disappears, thereby causing the immediate stop of the sheet feed roller 14 and eccentric cam 13.

Title: Controlling method of servo motor for compensating frictional torque
Inventor: YAMAMOTO YOICHI
IPC: G05B19/19
Filed: 1985-01-24
Abstract: PURPOSE:To compensate the vibration and the response delay of a motor by momentarily charging the charge corresponding to the sum of a frictional torque and an accelerating torque in an integrating capacitor in the rotating direction of the motor when the motor starts rotating and reverses its direction. CONSTITUTION:When a command function generator generates a motor rotation starting signal pulse or rotating direction reverse signal pulse in Fig. (a) or a voltage of charge to be charged in an integrating capacitor C1 in Fig. (b), relays RE1, RE2 are turned ON at a side when the pulse in Fig. (a) rises, the capacitor C1 is charged, while the relays RE1, RE2 are turned ON at b side when the pulse in Fig. (a) falls, and returns to a proportional integral control. Since a speed command Vs and a detecting speed Vd are together zero when the motor starts rotating or reverses its direction, a current command Is can be momentarily controlled as shown in Fig. (d). Since the current command value is arbitrarily set to the decided command voltage in this manner, the delay of a servo system due to the frictional torque or an accelerating torque can be largely improved.

Abstract: PURPOSE:To detect a peak value of a duty input signal accurately in a wide range by providing a peak detector means, a trigger generating means and a sample hold means which have a high-speed response time and a relatively short hold time. CONSTITUTION:A peak value of an input signal obtained by a peak detector circuit 21 is inputted to a sample hold circuit 41 comprising a switch 42, a capacitor 43 and a buffer 44. A trigger pulse from a trigger generating circuit 31 is impressed as a sample clock on a clock terminal of the circuit 41 through a delay circuit 51. The total value of a period serving as a basis for setting the period of a trigger pulse is set so that an output frequency of the generator 31 may not exceed the maximum sampling frequency of the circuit 41, and the generator 31 has a function of dividing the frequency of the trigger pulse into a frequency whereat the circuit 41 can operate, when the frequency of the input signal is high. Every time when the sampling clock is impressed, the circuit 41 samples the peak value of the input signal from the peak detector 21, and an output signal corresponding to the peak value is obtained from an output terminal 61.

Title: Heat transfer tube with inner surface grooves
Inventor: MOCHIZUKI YOSHIHIKO
IPC: F28F1/40
Filed: 1992-01-27
Abstract: PURPOSE:To obtain small decrease in performance due to collapse of grooves when a heat transfer tube with inner surface grooves is mechanically extended by a tube extending tool. CONSTITUTION:A spiral groove of an inner surface of a tube is formed of a triangular crest 2b having a large height in contact with a tube expanding tool 6 and a crest 2a having a small height in no contact with the tool 6 or in very small contact therewith. Since the crest 2a having the small height is not varied in shape by mechanically expanding, its performance before expanding can be assured. Thus, a decrease in performance after the mechanical expanding can be suppressed to small. It is also used commonly as a heat transfer tube for hydraulically expanding a tube.
