Title: Word-line drive circuit
Inventor: MANOJI KUMARU
IPC: G11C11/407
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain a word line driving circuit which can be operated to receive address signals from a decoder circuit and to output the received address signals to one or a plurality of memory cells in a RAM as word line signals by gating. SOLUTION: A word line driving circuit is constituted so that none of its internal nodes 112, 113, 114, and 115 provided between circuit elements can have any floating potential. Therefore, the oscillation of outputted word line signals can be prevented. This function is fulfilled by means of a plurality of circuit elements individually arranged to prevent the floating of internal nodes.

Title: Synchronous motor with load detector
Inventor: HANAOKA TOSHIKI
IPC: H02K21/14
Filed: 1994-06-10
Abstract: PURPOSE:To minimize the error component caused by interlocking the power supply voltage for a self-excited CR oscillation circuit with the voltage of drive power supply for the motor and varying the trigger voltage for self-excited oscillation thereby offsetting the load being applied to a rotor and the part dependent on the fluctuation in the voltage of the driving power supply. CONSTITUTION:Waveform 1 of the terminal voltage VC of a capacitor Cf makes a transition between trigger voltages VTH1 and VTL1. The trigger voltage VTH1 depends only on the signal from a detection coil 45 whereas the trigger signal VTL1 depends only on the voltage of a power supply 64 at an oscillation circuit. When the voltage of a power supply 50 for driving a motor drops, the trigger voltage VTH1 drops and since it can not be discriminated from the voltage drop caused by increase of load torque, frequency of the output signal increases. In order to correct the voltage drop, the trigger voltage is lowered down to VTH2. Since the correction amount is substantially proportional to the variation of voltage of the power supply 50, the power supply circuit at the oscillation circuit is constituted such that the correction amount is proportional to the variation.

Title: Controlling device of ventilation fan
Inventor: MIYAGI HIDEO
IPC: F24F7/007
Filed: 1982-07-23
Abstract: PURPOSE:To provide to the titled device an increased safety in an emergency of fire, by providing thereto a detective section for ventilation adapted to detect the rise of room air contamination above a preset level and actuate a ventilation fan, and a temperature detective section adapted to detect an abnormally elevated room temperature and cause the ventilation fan to stop. CONSTITUTION:An air contamination detective section 1 functions to detect the extent of room air being contaminated, and compare 2 it with a preset value for turning ON the transistor Q1 of output section 3 to actuate a ventilation fan 5. During this step, a normal room temperature does not actuate a temperature detective section 4. However, the resistor R1 of temperature detective section 4 and the thermistor RTH reduce their potentials upon a fire raising the room temperature to an abnormal level, and a comparator CP compares the magnitude of potentials with a reference voltage for turning OFF a transistor Q2 to forcibly stop the ventilation fan 5 if the potentials are smaller. This arrangement can secure the safety in the breakout of fire.
