Title: Memory device
Inventor: SATO NOBUYUKI
IPC: G06F12/16
Filed: 1990-03-29
Abstract: PURPOSE:To prevent a system down despite the occurrence of a memory error by allocating the address of an invalidated memory block having an error to another memory block and securing the continuous addresses of memory blocks except the invalidated one. CONSTITUTION:When a parity error occurs in the memory blocks 3-0 - 3-7, a RAS (row address strobe) CAS (column address strobe) signal 100 is cut by the RAS CAS selectors 1-0 - 1-7 to the blocks 3-0 - 3-7. Thus these memory blocks are invalidated. The address of the invalidated one of blocks 3-0 - 3-7 is allocated to another one of these blocks. Thus the continuous memory blocks are secured by the blocks 3-0 - 3-7 excluding the invalidated one. In such a constitution, a system down is avoided despite the occurrence of a memory error.

Filed: 1993-04-09
Abstract: PURPOSE:To easily provide the keyboard device, which can operate at a low voltage of about 2V, with an N-key rollover function and to sufficiently secure a noise margin. CONSTITUTION:This keyboard input device has a level converter 4 which outputs a scanning signal of CMOS level in order from scanning lines X0-X7 connected in the row directions of a resistance type key matrix 1 and a limiter 3 which limits a detection voltage by receiving a scan-in voltage by the ON/OFF operations of switch parts S00-S77 from detection lines Y0-Y7 connected in the column direction of the resistance type key matrix 1. A control unit 5 judges whether the switch parts are ON or OFF through the level converter 4 and limiter 3. Thus, the limiter 3 limits the scan-in voltage, so the N-key rollover function is obtained even in environment of 2V operation.

In addition, the output of position detector 13 controls power rectifiers 8A∼8C with the feedback signal from a speed reference setter 21 and current detector 25, controlling the electric motor 10's torque. At the same time, the said output is supplied to pulse amplification circuits 31∼33 obtaining signal deviated at prearranged angle, ignition-controlling power inverters 11A∼11C. Consequently, it is possible to deviate the output current of power inverters 11A∼11C at certain angle and approximate it to a sinusoidal wave by overlapping it. Thus torque ripple can be alleviated.

Title: Suspension system mounting device for vehicle
Inventor: HAMADA KAZUTAKA
IPC: B60G7/02
Filed: 1981-05-29
Abstract: PURPOSE:To improve the stability of maneuverability and antivibration property of a vehicle by reducing the widthwise thickness of an elastic insulator in the vertical central portion of a car body less than that in both ends. CONSTITUTION:When the widthwise (A-A) input is applied to an elastic insulator 32 in a suspension system mounting device 21, the insulator 32 is comressed or tensioned in the direction of A-A. Since the widthwise thickness of the insulator 32 in the central portion is small and instead the thickness of a metal intermediate plate is large, the rigidity in the direction A-A is large and the elastic deformation is small. Thus, relative displacement of a suspension member 22 and side member 24 in the direction A-A is small, and compliance steering in turning a vehicle can be minified to provide high stability of maneuverability.
