摘要： A heater energization control apparatus. When an engine is stopped, a microcomputer of a GCU enters a power save mode. When the microcomputer returns to a normal mode in response to an interruption signal periodically generated from an interruption timer, the microcomputer supplies electricity to a heating resistor for a short time and obtains its resistance (S19). When the resistance is greater than a first reference value, the microcomputer determines that a glow plug is removed from the engine; that is, the glow plug is being exchanged (S29). The microcomputer sets an exchange flag to “1” (S30), and performs calibration for the heating resistor of a new glow plug after the engine is operated next time (S35). When the current resistance becomes smaller than the past resistance, the microcomputer determines that the glow plug has been exchanged.

摘要： [Object] To provide a heater energization control apparatus which can detect that a heater has been exchanged.[Means for Solution] When an engine is stopped, a microcomputer of a GCU enters a power save mode. When the microcomputer returns to a normal mode in response to an interruption signal periodically generated from an interruption timer, the microcomputer supplies electricity to a heating resistor for a short time and obtains its resistance (S19). When the resistance is greater than a first reference value, the microcomputer determines that a glow plug is removed from the engine; that is, the glow plug is being exchanged (S29). The microcomputer sets an exchange flag to “1” (S30), and performs calibration for the heating resistor of a new glow plug after the engine is operated next time (S35). Further, since the resistance of the heating resistor changes (increases) with deterioration of the heating resistor with time, the acquired resistance may be stored. When the current resistance becomes smaller than the past resistance, the microcomputer determines that the glow plug has been exchanged.

摘要： A GCU (21) includes calibration means (33) which supplies electric current to a glow plug (1) when an internal combustion engine EN to which the glow plug (1) is attached is stopped, to thereby obtain a pre-correction target resistance of the glow plug (1). The calibration means (33) supplies a predetermined first electric power to the glow plug (1) in a predetermined first energization period, and supplies a predetermined second electric power to the glow plug (1) after the first energization period. The second electric power is set such that, when the second electric power is supplied to the glow plug (1) and the temperature of the glow plug (1) becomes saturated, the temperature of the glow plug (1) becomes equal to the target temperature. Further, the first electric power is greater than the second electric power.

摘要： In a selected column, a pull-up transistor pair is not selected but, instead, a transmission gate transistor pair is selected. In the read mode, the transmission gate transistor pair serves as pull-up loads between the bit line pair. However, the transmission gate transistor pair is kept off until the voltage across the bit line pair is decreased from the power supply potential level to the threshold voltage level of the transmission gate transistors. Therefore, no DC current path is formed in the bit line pair when the voltage across the bit line pair is within a range from a voltage equal to the power supply potential level to a potential lower than the power supply potential by an amount equal to the threshold voltage level, and the rate of increase of a potential difference across the bit line pair is determined by a pull-in current of the memory cell. Therefore, a high-speed sense operation can be realized. In the write mode, the transmission gate transistor pair serves a bit line pull-up function. Since no normally-ON bit line load transistor is arranged, no direct current path including the bit line pair is present, and hence, low power consumption can be achieved.

摘要： The threshold voltage of bit line percharge/equalize MOS transistors is smaller than that of normally ON type bit line pull-up transistors. With this feature, there is no current flows through a bit line from power source V.sub.DD during a read-out operation. The voltage difference between a pair of bit lines can be increased at high speed, thereby increasing the read-out speed.

摘要： A flush toilet 1 has a toilet flushing tank device 7 for discharging flushing water to a toilet bowl 2. This tank device is built into a tank storage region 5 to the rear of the toilet bowl 2, and comprises a flushing water tank 8 and a jet pump 13 disposed submerged in this flushing water tank 8. Flushing water (operating water) is supplied to this jet pump 13 via a flush valve 11 and a pipe 12 downstream from this valve. The jet pump 13 comprises a spray nozzle 131 and a throat 132 opposite thereto. Because the jet pump 13 is connected directly to a pipe 14, all of the flushing water jetted from the jet pump 13 passes directly to the pipe 14, and is guided by this pipe 14 to a rim water channel 4b.

摘要： During a data-clearing operation, while maintaining in the OFF state the transfer gate transistors in each of the static type memory cells associated with at least one column, the source of one of two drive transistors incorporated in the memory cell is set to a high potential level, and the source of the other drive transistor to a low level. As a result, the clearing operation is performed to a minimum of 1 column in the memory cell matrix. Due to the arrangement of the memory device, no address-selecting operation is required for selecting a memory cell during the clearing operation. Moreover, the clearing operation is carried out in a minimum unit of 1 column in the memory cell matrix. Consequently, the processing time for the clearing operation is reduced. Furthermore, the DC current flowing during the clearing operation is reduced, since the transfer gate transistor in the memory cell is maintained in the OFF state during the clearing operation, with the result that the power consumption is lowered.

摘要： Voltage converters are arranged in units of columns in a memory device. Each voltage converter is connected to a column decoder. The column decoder receives a column address signal and supplies a column selection signal to the voltage converter. The voltage converters apply a ground level voltage to the source junctions of the drive transistor pairs of the memory cells of the selected columns, and a voltage higher than the ground level voltage to the source junctions of the drive transistor pairs of the memory cells of the nonselected columns so as to decrease power consumption in the nonselected columns as compared with that in the selected columns.
