Abstract: PURPOSE:To attain the refresh of a DRAM of 256k bits by activating a RAS signal according to a memory access signal inputted during a refresh period at every M1 cycle, activating a CAS signal before the activation and holding the state during the period of the M1 cycle. CONSTITUTION:According to the memory access signal inputted externally during the refresh period at every an instruction fetch (M1) cycle, the row address strobe (RAS) signal is activated, before the activation, the column address strobe signal (CAS) is activated, and the state is held during the period of the M1 cycle of the cycle. A RAS26, since an FF5 is reset in T3 and T4 states, is charged according to the memory access signal 23. A CAS28 continues to be '0' until the inverse of Q output of an FF2 goes to '0' at the leading of the initial clock signal 22 of a next M1 cycle and an FF3 is set. Thus, during the refreshing period of the M1 cycle, the CAS is activated before the RAS is activated, thereby, the refresh of the DRAM of 256k bits can be performed.

A value for varying the conveyance speed of the recording medium at the fixing device 18 is obtained from the magnitude of the speed difference, then the conveyance speed at the fixing device 18 is varied.  As a result, an amount of loop of the recording medium P is maintained in a constant level, thereby a stable conveyance of the recording medium P can be attained.

Title: Stroboscopic device
Inventor: HARADA YOSHIHITO
IPC: H05B41/32
Filed: 1994-07-04
Abstract: PURPOSE:To reduce the energy loss of a stroboscopic device by using a voltage raised with a CMOS charge pump circuit as a drive source for the gate of an isolated gate bipolar transistor. CONSTITUTION:When field effect transistors(FETs) Q1 and Q3 are turned on, a motor 18 rotates in the normal direction, while the motor 18 rotates in the reverse direction when FETs Q2 and Q4 are turned on. Also, when FETs Q2 and Q3 are turned on, the motor 18 is braked. Furthermore, when all of the FETs Q1 to Q4 are turned off, the motor 18 becomes free from operation. Since each of the FETs Q1 to Q4 is power MOSFET it is turned on when a voltage at Vpp level is applied to the gate thereof. In general, the power MOSFET has a gate insulated and, even when switched with the power supply voltage Vpp of a CMOS charge pump circuit CHP, it suffers only a small loss. In addition, the power MOSFET can perform a high-speed switching operation. Thus, the power MOSFET becomes compatible, when it is driven with the power supply voltage Vpp of the circuit CHP.
