Patent JP-H0745795-A (JP)
Title: Semiconductor storage device
Inventor: KASHIHARA HIROTSUGU
IPC: H01L27/10
Filed: 1993-07-30
Abstract: PURPOSE:To obtain a chip architecture effective in high speed operation for semiconductor storage devices of multi-IO configuration with a center power pin system. CONSTITUTION:A memory cell array is divided into two in the direction of shorter side and in the direction of longer side of the chip 100 to obtain four mats A-D in total. Data of each mat A-D is input or output through the input/ output pad DQ the nearest to the relevant mat. Division in the shorter side direction halves the length of each bit line, and division in the longer side direction halves that of each data bus line RD, which reduces load capacity. Reduced load capacity of the bit lines and the data bus lines improves access speed.

IPC: G06F1/12
Filed: 1988-07-28
Abstract: PURPOSE:To detect the synchronized output signal of an asynchronous input signal by inputting the output of an asynchronous input circuit to two buffer circuits having different threshold levels and outputting the exclusive OR of the output signals of the buffer circuits. CONSTITUTION:The asynchronous input signal S1 inputted to an input terminal 1 of an IC is transmitted to 1st and 2nd FF 4a and 4b via an input buffer 2 consisting of two inverters 3a and 3b and synchronized with the clock signals phi1 and phi2. Then the output signal SQ5 of the FF 4b is transmitted to an internal circuit 13 of an IC via an inverter 1 from an output terminal theta5 of the FF 4b. The output terminal Q5 outputs an intermediate level M and at the same time the output signal S6 of the inverter also outputs a nonlogical intermediate level M. In such a case, an inverter IH having the threshold level H higher than the level M outputs 1(SH). While an inverter IL having the threshold level L lower than the level M outputs 0 respectively. Then a deciding signal S0 that defines the state as an exclusive OR is outputted to a register 10 from a deciding circuit 9.

Title: Toner feed controller
Inventor: SATOU KOUJI
IPC: G03G15/00
Filed: 1981-11-28
Abstract: PURPOSE:To feed a toner in a simple and assured way and to perform the development with the stable concentration, by controlling the operations of a printer, a toner hopper, a toner feeder, etc. respectively in response to the toner request signal. CONSTITUTION:The presence is decided at step 1 for the toner request signal S3. When the signal S3 exists, a toner hopper motor 12 is actuated while performing a printing action until the signal S3 disappears. The duration time T of the signal S3 is counted. Then it is recognized at step 2 that the print picture density is high when the T1 elapsed and the signal S3 continues. Thus a print-not- ready state is once obtained. If the signal S3 continues yet at the time T2, it is decided that the toner is exhausted in a toner hopper 9. Then the motor 12 and a printer are stopped at step 3. The toner is supplied at step 4, and the print is started at step 5. If a switch 57 is turned on with no supply of the toner, the original state is reset to start counting.

Abstract: PURPOSE:To stabilize the car attitude and improve drive feeling by increasing the spring constant or damping force of a suspension at the initial stage of brake application and further increasing the spring constant or damping force when the variation rate of car speed with time becomes over a set value. CONSTITUTION:When a brake switch 21 is turned-ON by stepping-in a brake pedal, the variation rate of car speed with time is calculated on the basis of the detection value of a car speed sensor 22 by an F-V switch 24 and a differentiation circuit 25 in a control part 23, and the calculation value is compared with a set value in a comparator 26. When the variation rate of car speed with time is over the set value, the sharp brake state is judged, and the actuators 29 and 30 are driven by a driving circuit 28, and the spring constant or damping force of a suspension is switched to the highest hard state, and the change of attitude of the car is prevented in preference to the drive feeling. When the variation rate of car speed with time is below a set value, the spring constant or damping force is switched to the normal state.
