Title: Control method, controller and timer of stepping motor
Inventor: KUBOTA MASARU
IPC: G04C3/14
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To minimize the power consumption of a stepping motor by a method wherein the effective powers of driving pulses supplied to the stepping motor are set for the respective rotation positions of the stepping motor. SOLUTION: A stepping motor 10 is a 2-pole motor having 2 phases. A controller 20 decides the position of the stepping motor 10 from which the rotation of the rotor 13 is started. That is, it is decided whether a 1st step angle from a 1st phase to a 2nd phase is driven or a 2nd step angle from a 2nd phase to a 1st phase is driven. A large pulse signal P1 (2) whose width is wide and effective power is large is outputted for the 1st step angle. On the other hand, a small pulse signal P1 (1) whose width is narrow and effective power is small is outputted for the 2nd step angle. It is to be noted that data with which signals with required pulse widths are selected among signals with pulse widths which can be outputted from a waveform synthesizing circuit 25 are stored in setting circuits 26a and 26b.

Title: Communication controller
Inventor: SATO SHINICHI
IPC: H04L29/02
Filed: 1985-04-08
Abstract: PURPOSE:To attain high speed data communication by using a separate control circuit independently of a microprocessor controlling the entire control of a communication controller for data reception control in the unit of one character. CONSTITUTION:When one character of a data sent via a communication line 4 is received by a line control circuit 5, the line control circuit 5 informs of one character reception to a control circuit 10. When the reception of one character is informed, the control circuit 10 starts operation according to the program. That is, a reception data is read by one character from the line control circuit 5 in the step 21 and discriminates the read reception data in the steps 22-24. When the character received at first is STX41, a data reception flag is set on in the step 25 to stop the system. In receiving a data part 42 next, after the control circuit 10 confirms that the data reception flag is set on in the steps 26-27, the data part 42 is directly transferred to a reception data buffer in the memory 3 form the line control circuit 5 by using a DMA control circuit 12. In receiving finally an ETX 43, the steps 28 30 are executed.

Title: Vibration controller for rolling stock
Inventor: AKAMI YUSUKE
IPC: B61F5/24
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To permit detection for breakdown by a simple structure. SOLUTION: This vibration controller judges breakdown judgment for each vehicle based on signals from each controller through a serial communications line. When a fail vehicle is a vehicle positioned in front of or behind the vehicle itself, either of the processings is conducted; making the damping force of the own vehicle (expansion side and shrinking side) into a hard state (step S72), or executing adjustment so that the damping force of the vehicle positioned in front of or behind the own vehicle becomes 2/3 of the maximum values (step S74 and S75). Signals are transmitted and received between a plurality of controllers, thereby mutual understanding of the breakdown judgement conditions of other vehicles is possible. Moreover, the damping force of the vehicle positioned forward or rear of the fail vehicle is adjustable.  With this, the stable running as an entire vehicle is maintained compared with the case where the damping force of the fail vehicle is adjusted.

Abstract: PURPOSE:To correctly cut a paper towel at a sewing stitch by stringing an endless belt between a feeding roller and a drawing roller and causing the diameter of a circle to form the bottom surface of the grooves of the feeding roller to be smaller than the diameter of the drawing roller. CONSTITUTION:A feeding roller 47 and a drawing roller 49 of the same diameter are fixed in the central parts of shafts 45 and 46 in being faced. For the roller 47, a groove 47a is formed over a full circumference on the circumferential surface, and the diameter of the circle to form the bottom surface of the groove 47a is smaller than the diameter of the roller 48. An endless belt 49 is strung between the circumferential surface of the roller 48 and the bottom surface of the groove 47a of the roller 47, and it works also as a power transmitting means. By such a constitution, when the feeding roller 47 is rotated in a speed faster than that of the drawing roller 48, a force is added to the sewing stitch, and since an opening can be formed in a prescribed distance along the sewing stitch, the paper towel can be correctly cut along the sewing stitch.
