Title: Semiconductor memory
Inventor: YAMAZAKI KAZUYUKI
IPC: G11C29/42
Filed: 1999-05-19
Abstract: PROBLEM TO BE SOLVED: To obtain a mask ROM which is effective for a large capacity mask ROM mounted with an ECC and has both of high speed access and a relief effect. SOLUTION: At the time of selecting memory cell arrays (C0 and C1) 1 being distant from a word selecting line driver 12, data read out from the cell are transmitted to an output buffer circuit (OB) 11 through a sense amplifier circuit (S0, S1) 7, and at the time of selecting memory cell arrays (C2 to C7) 1, data read out from the cell are transmitted to an output buffer circuit through sense amplifier circuits (S2-S7) 7, an error detecting circuit (ECC1) 8, a syndrome decoder (ECC2) 9, and an error correcting circuit (CR2 to CR7) 10.  Consequently, for memory cells (C0, C1) which have large resistence capacity of word selecting lines and hence the read-out of a sense amplifier is greatly delayed compared to read-out of a memory cell at the root of the word selecting line, data are outputted without passing through ECC circuits 8, 9, and for memory cells (C2 to C7) in which resistance and capacitance of the word selecting line are small and a read-out time is the same as the read-out time of a memory cell at the root of the word selecting line, data are outputted after correcting an error through the ECC circuit 8, 9.

Patent JP-S621674-A (JP)
Title: Four-wheel steering gear for vehicles
Inventor: INOUE HITOSHI
IPC: B62D6/00
Filed: 1985-06-26
Abstract: PURPOSE:To prevent a wheel from skidding at a rough road as well as to aim at improvement in driving stability, by making the ratio of a front-wheel steering angle to a rear-wheel steering angle variable according to a steering ratio characteristic, while installing a device which compensates this steering angle ratio in the same phase direction. CONSTITUTION:When a car drives on a rough road with a four-wheel drive, a characteristic selecting part 45 receives an output signal out of a driving state detecting device 28 and selects a steering ratio characteristic B for four- wheel drive time use in place of a steering ratio characteristic A for two-wheel drive time use from a characteristic memory part 40, and according to this, a steering ratio is variably controlled by a steering ratio variable device 44. At this time, since the steering ratio characteristic B is shifted to the same phase side as compared with the steering ratio characteristic A, rear wheels are steered in the same phase direction as front wheels rather than at the time of the two-wheel drive, thus car turning is checked. With this constitution, a skid in these wheels attributable to a drop in grip force to a road surface at the rough road is preventable from occurring, thus driving stability is improvable.

Title: Safety device for elevator cage derail
Inventor: TAJIMA HITOSHI
IPC: B66B3/00
Filed: 1977-11-21
Abstract: PURPOSE: To provide a safety device which controls the operation of an elevator such as a cage and a counterbalance weight or the like by generating a sound wave from a sound wave generator when the elevator is derailed by detection and converting the sound wave into an electric signal to operate when the electric signal exceeds predetermined value.  
     CONSTITUTION: When at least one of guide rollers 5 is derailed from a guide rail 2 due to an earthquake or the like, a derail detector 8 is closed at its contact to cause a sound wave generator 9 to ring. After this sound is converted through sound- electric converters 11a, 11b into electric signal, it is applied through an adder 12 and an amplifier 13 to a filter 14, which thereupon removes other frequency components from the signal due to external disturbance. After the frequency signal of the sound passed through the filter 14 is rectified by a rectifier 15, it is fed to an integrator 16. The output from the integrator 16 is applied to a comparator 18, and when it exceeds a standard signal 17, a derail detection signal is fed from the comparator 18 to an elevator cage controller.

The signal is amplified by a motor driver 7, output to the motor 1, and its speed is controlled in an accelerating direction. The discriminator 8 has a speed detecting function, and obtains a low level output when a motor speed falls within a predetermined speed. This signal is a READY signal, the logic product of a deceleration pulse signal and the READY signal is taken by an AND gate 9a, thereby controlling a switch element SW thereby to increase a discharge amount (gain) via a resistor Rd. As a result, the settling time of a servo is shortened.
