Title: Semiconductor device
Inventor: KAJITANI KAZUHIKO
IPC: G11C11/406
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To reduce bit line charging and discharging currents made to flow to a sense amplifier by using a prescribed input pin among plural input pins for receiving a prescribed signal other than a column address and a row address in a time division manner. SOLUTION: The number of times of the refresh operation of a memory cell is made more than 1/2n and the number of the sense amplifiers activated by one refresh operation is made less than 1/2n. In the case that a row address number and a column address number are different, the unsuppliable addresses of a larger number are inputted from a signal pin other than an address pin in a time division manner. In the case of turning a reflex cycle number to 1/2n and turning the number of the sense amplifies to be simultaneously activated to 1/2n for the capacity of (n) bits, one word line is selected by the row address and the 1/2n memory cells connected to it are activated.  Combining with the three-dimensional structure memory cell of a type for not using a substrate as the electrode of storage capacity for improving information holding characteristics is performed and power consumption is reduced.

Title: Ic memory card
Inventor: ENDO YUICHIRO
IPC: B42D15/10
Filed: 1989-12-18
Abstract: PURPOSE:To preserve a game content and to restart a game by reading preserved data by incorporating a mask ROM and an EEPROM as an IC memory, and providing a controller for preventing concurrent operation of the ROM and the EEPROM. CONSTITUTION:An IC memory card 1 places a mask ROM 2 and an EEPROM 3 on a plastic board made of ABS resin, etc. Many external terminals 4 are connected to the connector of a pate body. The ROM 2 and the EEPROM 3 are connected to the terminals 4 through printed wirings, and prevented from being concurrently operated by a controller 5. Since the controller 5 is provided, even if a game is interrupted on the way, the content of a game at that time point is preserved in the EEPROM 3. If the game is desired to be restarted, the game can be continued by reading data. Further, since a cell is not required, there is no fear of erasing the data due to consumption of the cell.

Title: Controller for vehicle with learning function
Inventor: ITO YUJI
IPC: G06F9/44
Filed: 1995-12-15
Abstract: PROBLEM TO BE SOLVED: To stop unsuitable learning and to execute suitable learning control with a controller for vehicle. SOLUTION: The position of seat 1 of a driver is detected by position sensors 6 and 7 and previously stored by operating a switch 12a. When the driver changes air quantity into different air quantity by an air quantity switch 10a while an ECU 8 for air conditioner controls a blower motor 9 by the voltage decided based on environmental conditions or the like by various sensors 11, etc., and only when the current seat position detected by the position sensors 6 and 7 is coincident with the stored seat position, the control characteristics of ECU 8 for air conditioner are learnt so as to provide that changed voltage of blower motor 9 by relating the environmental conditions, etc., by the various sensors 11 or the like used for deciding the voltage of blower motor 9 at that time with the changed voltage of blower motor 9.  Since the control characteristics are not learnt even when any driver except for the owner of vehicle changes air quantity, that air quantity is not provided even when the same environmental conditions are established later.

IPC: B62D5/04
Filed: 1990-11-30
Abstract: PURPOSE:To properly detect the error of an electric motor control circuit by providing a control circuit error detection means for detecting the error state of the electric motor control circuit, and an error control means for invalidating the aforesaid circuit upon detection of an error. CONSTITUTION:At the time (t1) when an error occurs in an electric motor control circuit 5 and a control signal Vc from a zero point adjustment circuit 18 exceeds an upper limit setting voltage VSH, the output of the differential amplifier 51 of a control circuit error detection circuit 46 turns to a low level. An error latch circuit 46 correspondingly outputs a logic value '0'. Consequently, pulse output signals PA and PB from AND gates 20A and 20B are interrupted, and power supply to the relay coil 32b of an external relay 32 from an external relay driver 47 is interrupted. Subsequently, the contact 32a of the relay 32 opens, thereby interrupting power supply from a battery B to the electric motor drive circuit 6. As a result, an electric motor 3 is controlled at a rotation stop state, and stops generating torque to assist steering.
