Title: Method and circuit for driving 5-phase stepping motor
Inventor: ANDO JUN
IPC: H02P8/22
Filed: 1994-02-09
Abstract: PURPOSE:To reduce noise and vibration in multi-split driving of a stepping motor by controlling the output duty of 2-phase pattern through ROM data change and digital control by a selector. CONSTITUTION:A selector 3 can change a 2-phase excitation pattern as necessary by receiving duty data from a ROM each sequence displayed on an N-ary counter, and changing the memory pattern of the ROM on the basis of the data. When connecting connection points to a positive or negative pole by controlling the switching of a switching means (Tr), one of the 2-phase excitation patterns, in which two connection points are connected to a positive pole and three points are connected to a negative pole, is kept to a constant output duty, and the output duty of the other 2-phase excitation pattern and a 2-phase excitation pattern, in which four connection points are connected to a positive pole and one point is connected to a negative pole, is gradually increased or decreased. Thus, multi-split driving of 4-/5-phase excitation is carried out, thus reducing vibration of a stepping motor.

IPC: H04L1/00
Filed: 1986-02-25
Abstract: PURPOSE:To attain a data transmission system which is free from the occurrence of undesired collision of data by securing such a constitution where the transmitter of the transmitter side sends the post-ambles continuously to a transmission data frame and the transmitter of the receiver side transmits the prescrined data after detecting a reception error to inform the data reception error. CONSTITUTION:A transmission buffer 2 stores those data on the frame control 152 through the frame check sequence FCS156. A transmission control circuit 3 checks whether or not a carrier detecting circuit 8 detects a carrier out of a communication medium 12. Then the circuit 3 outputs a pre-amble transmission request to a pre-amble generating circuit 4 after confirming that no carrier is detected, i.e., the medium 12 has the idle information. Then the circuit 4 transmits a pre-amble 151 onto the medium 12 via a transceiver 6. Then it is checked whether or not a collision detecting circuit 7 detects a collision. If the occurrence of the collision is confirmed, the transmission of data is discontinued for a fixed time decided by the back-off algorithm. Then a post-amble generating circuit 5 transmits again a data transmission frame after a prescribed time is elapsed.

Abstract: PURPOSE:To conduct test without disturbing communication between subscriber terminal devices during operation by discriminating whether or not a control signal is received correctly by a signal reception circuit through a series connection of a conference talking circuit, a time division exchange circuit and a control signal generating circuit. CONSTITUTION:When a tone signal is received correctly, it is confirmed that the conference talk in circuit 13a and the time division exchange circuit 11 function correctly respectively. However, if the tone signal is not received correctly, it is discriminated that the circuit 13a or the circuit 11 has a fault.

When it is confirmed that the said tone signal is received correctly by the changeover to the circuit 13b, it is discriminated that the said fault exists in the circuit 13a. On the other hand, when the said tone signal is not correctly received even with the connection changeover of the circuit 13b, it is discriminated that the said fault exists at least in the time division exchange circuit 11. Thus, the time division exchange circuit 11 and the conference talking circuit 13 are tested.
