Title: Screening method for mos dynamic ram
Inventor: MATSUMOTO HEIHACHI
IPC: G11C11/401
Filed: 1984-01-25
Abstract: PURPOSE:To enable the screening of defective ones of thin oxide films to be accomplished in a short time at the time of wafer test by a method wherein defective ones of the thin oxide films of memory capacitors are broken down by impressing a high voltage from the back side of a wafer. CONSTITUTION:A wafer is heated at the time of wafer test; a bias of 5V is given to an electrode 7, and a negative bias to the wafer back, and other terminals are all set at 0V. The bias given from the wafer back is a voltage of the degree that a P-N junction does not generate avalanche breakdown, and prevents the flow of large current. For example, when a bias of -17V is impressed on the wafer back at 125 deg.C, the bias impressed on a thin oxide film becomes about 16V because of a leakage current, and the electric field becomes 4MV/cm. Therefore, 20hr-burn-in becomes the screening effect equal to 0.3sec-stress impressing; consequentily, it is necessary to impress the -17V bias for 0.4sec.

Title: Polyphase thyristor motor controller
Inventor: OKUYAMA TOSHIAKI
IPC: H02P23/04
Filed: 1979-02-13
Abstract: PURPOSE: To reduce the torque ripple of a polyphase thyristor motor and the size of a DC reactor by conducting anti-parallel thyristors connected between the connecting point of a plurality of power supply side converters and the connecting point of a plurality of motor side converters in the low speed range of the motor.  
     CONSTITUTION: When the rotating speed of a synchronous motor 5 is lower than predetermined value, any of thyristors 10, 11 is conducted according to the direction of an electric current. The output currents of converters 2, 3 are alternatively controlled to be interrupted to communicate converters 6, 7. Since the output currents of the converters 2, 3 are controlled in the same manner while the converters 6, 7 are not commutated, the thyristors 10, 11 are turned off to flow no current therethrough. Since the output current of one converter becomes zero while the converters 6, 7 are commutated, the output current of the other converter is flown through the thyristors 10, 11. When the rotating speed of the motor is higher than predetermined value, the converters 6, 7 are commutated by the counterelectromotive force of the motor to break the gate signals of the thyristors 10, 11.

Title: Memory contents destruction test system in power failure
Inventor: NAGANO AKIRA
IPC: G06F1/00
Filed: 1978-02-09
Abstract: PURPOSE: To make it possible to inspect easily whether data stored in a non-volatile memory is destroyed or not at a power failure time.  
     CONSTITUTION: At a power failure occurrence time, power state detector circuit 1 leads out the power failure detection output and gives it to CPU 2. Since CPU 2 can operate normally for the time of approximately 100msec. due to the action of a capacitor included in the power source circuit even at a power failure time, CPU 2 saves data M 1  to M n  stored in RAM 3 to areas 41 to 4n of non-volatile memory 4 and executes the subroutine for check word generation. That is, check CWa is generated by accumulator (ACC) 21 on a basis of data M 1  to M n  stored in memory 4, and further, Cwa stored in ACC 21 is transferred to area 4A of memory 4 and is stored there. Next, when power is restored, circuit 1 leads out the power restoration detection output and gives it to CPU 2, and CPU 2 executes the subroutine for generating CWb after power restoration and generates Cwb. Further, CPU 2 reads out CWa before power failure which is stored in area 4A, and compares CWa and CWb with each other in comparator circuit 22, thereby discriminating.

Abstract: PURPOSE:To keep a stable combustion for a long period of time by a method wherein  reduction of vaporized amt. of fuel caused by a tar material generated and accumulated at a fuel vaporization part in the wick part and a production of odor and CO etc. associated therewith are prevented. CONSTITUTION:Stable flame (f) is formed at the air holes 12 in an inner flame cylinder  2 during an initial period of time, latent heat of vaporization of the fuel is fed to a  fuel vaporization part 9a to generate a vaporized fuel. In this case, the air holes 12a- 12c having their opening diameters gradually decreased in sequence toward the upward  direction in opposite to the vaporization part 9a cause a mixing concentration of fuel  and air to show a high value and not to form any flame due to a low temperature of  the mixed gas, resulting in providing a stable combustion and a rated volume of combustion. Then, if the amt. of accumulated tar materials (ta) and (tb) is increased in the  vaporization part 9a after use of long period of time, the amt. of vaporization of the  fuel is reduced, the latent heat of vaporization is also decreased to cause elevation of  the temperature of atmosphere and the flames (fb), (fc) and the flame (fa) are formed,  the vaporization part 9a is heated by these flames to remove the tar materials (ta) and  (tb) and the like by a thermal decomposition and thereby the vaporization of the fuel  is promoted.
