Title: Receiving data extracting system
Inventor: KURASHIGE TAKEHIKO
IPC: H04L13/00
Filed: 1987-03-24
Abstract: PURPOSE:To extract transmitting data only from an opponent station, to send them to a serial input output control part and to prevent the receiving of self- station transmitting data by changing the condition of an FF in accordance with a self-station transmitting and receiving starting. CONSTITUTION:When a self-station and an opponent station are not transmitted, an FF29 of a receiving data extracting circuit 14 latches a D input signal with the rising of a transmitting/receiving clock supplied through a TXC/RXC terminal and a Q output is sent to the D terminal of an FF30. When Q of an FF24 is 'H', a signal from an opponent station on a receiving data line 46 is supplied to a serial input output control part through the FF29 and 30, a NAND gate 31 and a line 48. At the time of a self-station transmission a transmitting data line 44 comes to be 'L', the holding data of a register 21 is loaded to a counter 22 with the falling of the transmitting/receiving clock and the setting of the FF24 shows the self-station transmission. Thereafter, by the resetting of the FF24, the gate 31 sends a signal to show a mark condition to the line 48 and the straining of the self-station transmitting data is prevented.

Title: Memory device
Inventor: MORIKAWA MASAKI
IPC: G11B23/03
Filed: 1989-03-22
Abstract: PURPOSE:To dispense with a system memory consisting of a magnetic disk, etc., and to attain a long service life by providing a user memory consisting of a nonvolatile memory, the system memory consisting of a volatile semiconductor memory, and a backup memory consisting of an electrically reloadable nonvolatile semiconductor memory. CONSTITUTION:The volatile semiconductor memory is used as the system memory 12 to store system data corresponding to the user memory 11. Furthermore, the electrically reloadable nonvolatile semiconductor memory(EEPROM) is used as the backup memory 13 to store the system data by performing backup for the system memory 12. Therefore, an operation is simplified differently from a case where the magnetic disk is used as the system memory, and also, the constitution of a driving device can be simplified, and also, the input/output of data can be accelerated. At such a case, the EEPROM is used for the backup, and the number of times of rewrite can be remarkably reduced compared with that in the system memory 12 itself. Thereby, the problem of a service life can be evaded.

IPC: B62D6/00
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To dissolve a lowering of steering wheel stability when a steering angle is large by generating self-alighting torque for restoring a steering wheel into a neutral position in a control means for controlling the operation of a motor-driven power steering for applying steering assist torque to a parallel geometry type steering system. SOLUTION: A target current setting means M1 of an electronic control unit U computes a target current IMS for driving a motor 27 of a motor-driven power steering S on the basis of steering torque T detected by a steering torque detecting means S1, a steering angle θ detected by a steering angle detecting means S2, vehicle speed V detected by a vehicle speed detecting means S3 and steering rotating speed N computed by a steering rotating speed computing means M2. A driving control means M3 converts the target current IMS into motor control voltage V0 and drives the motor 27 through a motor driver 32. At this time, a lowering of steering wheel stability is compensated by generating larger steering assist torque to the motor-driven power steering S in proportion to the increase of the steering angle and the decrease in the vehicle speed.
