Title: Electric power steering device
Inventor: TOMIOKA EIICHI
IPC: B62D113/00
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To make sensor installation space small, and reduce cost. SOLUTION: A steering angle sensor on the output side of a rotary shaft of a steering force assist motor (DC brushless motor) 1 is eliminated, and an absolute type rotary encoder 7 is installed on the rotary shaft of the motor 1 instead of a rotor position detection sensor. The absolute type rotary encoder 7 is conditioned to be capable of detecting an absolute position of a rotor relative to a stator of the motor 1, and have a high resolution. A fully electric power steering device (FEPS) controller 2 determines an energization changeover timing to a motor coil of the motor 1, and a steering angle (steering speed) based on a signal from the rotary encoder 7.

Title: Storage device
Inventor: KANATSU JUN
IPC: G06F12/16
Filed: 1989-05-15
Abstract: PURPOSE:To prevent an incorrectable error occurring by correcting data by storing the bit position of a one-bit error occurring in the past, and using a stored bit position when a two-bit error occurs. CONSTITUTION:When the two-bit error exists on an after correction data line 102, a circuit (ECC circuit) 3 incapable of detecting a data error, correcting the data up to a one-bit data error, and detecting the bit position in the one-bit data error informs the detection of the two-bit error to an error bit position storage circuit 4. At this time, the error bit position storage circuit 4 issues an instruction to a signal inversion circuit 2 so as to invert a specific bit posi tion on a readout data line 101 by activating an inversion instruction signal 104 corresponding to an error bit position stored in advance when the one-bit error is detected. The signal inversion circuit 2 inverts the specific bit on the readout data line 101, and outputs it to the after correction data line 102. The ECC circuit 3 performs an ECC arithmetic operation again by using the value of the after correction data line 102, and performs the correction, then, outputs it to an after correction data line 105. Thereby, it is possible to prevent the incorrectable error occurring.

Abstract: PURPOSE:To make a subscriber recognize a terminating status only by one relay, by using a calling signal source to output AC signals intermittently at a prescribed period. CONSTITUTION:The calling signal source OSC2 outputs an intermittent calling signal with a repeated period that the 20Hz AC signal is on for 0.8sec and off for 0.2sec as shown in (a).
