Title: Equipment and method for controlling stepping motor
Inventor: OKADA TAKAFUMI
IPC: H02P8/16
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To accelerate a stepping motor in a short time by a method wherein when switching the stepping motor from a low speed rotation to a high speed rotation, the amplitude of a driving signal is compard with the reference level to judge the position of a rotor and the driving signal for a high speed rotation is started from a state one step ahead. SOLUTION: When switching a stepping motor from a low speed rotation to a high speed rotation, it is judged based on the amplitude of a driving signal output from a first driving signal generating means 1A whether a rotor of the stepping motor is near a mechanically stable position. In the case that the rotor of the stepping motor is near the mechanically stably position, a second driving signal generating means 1B is instructed to output a driving signal for moving the stepping motor to a next mechanically stable position in the rotating direction of the stepping motor. By this method, there is no wasteful state at the time of switching the stepping motor from a low speed rotation to a high speed one and thereby the acceleration time required for a high speed rotation of the motor can be remarkably shortened.

Filed: 1992-04-01
Abstract: PURPOSE:To prevent the non-coincidence of received data by informing optical cable or opposite side optical repeater abnormality of a communication control equipment and switching transmission line systems when the abnormality is detected by the optical repeater device. CONSTITUTION:When an optical fiber 13 of a B system optical cable 19 marked by X is disconnected, for example, an optical repeater device 17 detects that no optical signal is inputted from the optical fiber 13 to an optical transceiver 15, and issues a message command reporting the abnormality of the optical cable 19 through an electric transceiver 14 to a coaxial cable 2. This message command is recognized by a communication control equipment 4s having the high priority order among communication control equipments 4, and a command 21 supporting the switching of transmission lines is issued to an A system coaxial cable 1 connected by a normal optical cable 18. Since the communication control equipments 4 at the coaxial cable 1 ignore communicated data in the B system, the identity of received data can be kept.

Filed: 1991-05-10
Abstract: PURPOSE:To detect a data format at high speed from reception data by means of a start-stop synchronous communication. CONSTITUTION:A clock generation circuit 1 outputs a clock 11 synchronized with the state change of reception data 10. A serial-parallel conversion circuit 2 converts one character of reception data 10 into parallel data 12 in accordance with the clock 11. A counter 3 counts the clock 11 and generates timing signals for respective characters and for respective commands. A reception character deciding circuit 4 decides whether parallel data 12 is an expected command or not. A register 5 holds a bit identifying the format from parallel data 12, and outputs a format identification signal 18. A control part 6 initializes a circuit when parallel data 12 differs from the expected command. The data format is noticed by the format identification signal 18 when a command reception completion signal 16 from the counter 3 becomes effective.
