A capacitor memory is realized, wherein a capacitor stores data and a diode controls to store data “1” or “0”. Diode has four terminals wherein first terminal serves as word line, second terminal serves as storage node, third terminal is floating, and fourth terminal serves as bit line, wherein back channel effect is suppressed adding additional ions in the bottom side of third terminal or applying negative voltage in the well or substrate. A capacitor plate couples to second terminal, which plate has no coupling region to first, third and fourth terminal. With no coupling, the inversion layer of plate in the storage node is isolated from the adjacent nodes. In doing so, the plate can swing ground level to positive supply level to write. As a result, no negative generator is required for controlling plate. Word line and bit line keep ground level during standby, and rise to supply level for read or write operation. In this manner, no holding current is required during standby, and operating current is dramatically reduced with no negative generator. Write has a sequence to clear the state of cell before writing to store data regardless of previous state. Refresh cycle is periodically asserted to sustain data. The present invention can be applied for destructive read, or for nondestructive read adding pull-down device to bit line. The height of cell is almost same as control circuit on the bulk or SOI wafer.

Accordingly, the heat generated by the LEDs of the LED module 11 is mostly dissipated by the heat dissipating unit 12, thereby suppressing the temperature of the lighting circuit from rising.

An object is subjected to high-pressure processing by bringing at least a high-pressure fluid into contact with the object under pressure in a high-pressure processing chamber, and then the high-pressure processing chamber is depressurized while the temperature in the chamber is controlled to be maintained above a temperature achieved by an adiabatic expansion, the adiabatic expansion starting from the pressure and temperature at the end of the high-pressure processing step. To control in such a way, the temperature in the high-pressure processing chamber is controlled so as to suppress or recover a temperature descent caused by an adiabatic expansion during the depressurizing step. This solves a problem in which the temperature is decreased to the vapor-liquid phase coexistence region or a region in which a solid is deposited.

First and second clutches correspond to systems which include “first gear” and “second gear,” respectively. When the temperature of the first clutch at the time of start of the vehicle is lower than a first temperature, only the first clutch is used as a start clutch for driving the vehicle.
