Title: Nonvolatile memory
Inventor: SAKAMOTO MAKOTO
IPC: G11C11/41
Filed: 1991-06-14
Abstract: PURPOSE:To obtain a nonvolatile memory which allows writing by a normal operation voltage. CONSTITUTION:Both ends of an SRAM 10 are connected to a line PL through a ferroelectric capacitor 16. Both ends of the SRAM 10 are connected with a switch 18. After the SRAM is set as specified, a switch 14 is turned ON to write a data into the ferroelectric capacitor 16. At the rising time, the switch 18 is turned ON with the switch 14 OFF to make both the ends of the SRAM 10 the same in phase. Then, under such a condition, the switch 14 is turned ON so that a potential difference based on a dielectric polarization at the ferroelectric capacitor 16 works on both the ends of the SRAM 10. Thus, the SRAM 10 is set according to the data written in the ferroelectric capacitor 16 and this eliminates the need for a high voltage in a nonvolatile memory.

Title: Deciding method for connection quantity of clutch
Inventor: HAYASHI TATSUYA
IPC: F16D48/02
Filed: 1988-06-10
Abstract: PURPOSE:To approximately equalize torque transferred to a transmission by measuring the semi-clutch starting position and the complete connection position of a clutch according to the condition of the input shaft of the transmission under the operation of the clutch, and calculating the connection quantity of the clutch for securing desired transfer torque according to the running condition of a vehicle and the distance between the above-mentioned positions. CONSTITUTION:A clutch which switches on and off the output of an engine to transfer the output to a transmission is operated from the condition under which it is completely off toward the condition under which it is completely connected. And the semi-clutch starting position of the clutch under operation is measured according to the condition of the input shaft of the transmission under the operation of the clutch, and also the complete connection position of the clutch is measured. Besides, the connection quantity of the clutch for securing desired transfer torque is calculated according to the running condition of a vehicle and the distance between the semi-clutch starting position and the complete connection position. The connection quantity may thus be decided in proportion to variation of the characteristics of transfer torque due to dispersion of the clutch components, and hence transfer torque can be equalized approximately.
