Title: Bidirectional dc-dc converter
Inventor: WATANABE ICHIU
IPC: H02M3/28
Filed: 1978-08-30
Abstract: PURPOSE: To manufacture a bidirectional DC-DC converter, by providing a transformer with two coils having intermediate taps and by connecting a pair of switches to both the ends of each coil.  
     CONSTITUTION: When switches S 11 , S 12  coupled to a coil N 1  are alternately opened and closed, a current flows from a DC power source E through the upper and lower half parts of the coil N 1  alternately and an alternating voltage is induced in another coil N 2 . The alternating voltage is rectified by opening and closing other switches S 21 , S 22  coupled to the coil N 2  so that a DC voltage is supplied to a load resistor R. The DC voltage is N 2 /N 1  times higher than that of the DC power source E. If the DC power source E and the load resistor R are replaced by each other, the same phenomenon takes placed in the opposite direction.

IPC: G11B5/52
Filed: 1988-04-28
Abstract: PURPOSE:To obtain a rotary drum with a balancer reduced at its vibration by providing the rotary drum with an annular part capable of freely moving liquid in an annular small room. CONSTITUTION:The annular part 8 having the sealed annular small room in which liquid can be freely moved under a state separated from gas is mounted on the rotary drum 1 so that the center axis of the annular part 8 coincides with the rotary shaft of the rotary drum 1 for a magnetic head of a video tape recorder. When the rotary drum 1 stats to oscillate, the liquid in the small room can not follow the oscillating direction of the rotary drum 1 due to the viscosity resistance of the liquid and the centroid of the drum 1 is moved in the reverse direction against the oscillation direction. Consequently, the return oscillation of the rotary drum 1 can be quickly reduced.

IPC: H01L21/28
Filed: 1979-08-21
Abstract: PURPOSE:To prevent the disconnection of wires in a semiconductor device by forming a gate in buried type and flattening the surface of the device. CONSTITUTION:A gate oxide film 12 is formed on a P type substrate 11, ions are implanted thereto, and P<+> type layer 14 and N type layer 16 are sequentially  formed thereon. A phosphorus-doped polysilicon film 17 and an Si3N4 film 18 are laminated thereon, a resist mask 19 is coated thereon, is ion etched, and the opened film 17 is reduced in thickness to approx. half. With the film 18 as a mask it is then annealed with a laser in an O2, and SiO2 films 20, 21 are formed thereon. In this case the film 18 is retained in the connecting portion, and a connecting photographic printing plate can be eliminated. Since no heat treatment is necessary after forming the source and the drain, an intrusion to the gate region can be reduced, and since the surface thereafter is reduced in thickness beforehand to a half of the film 17, the substrate can be flattened, and the conventional PSG film or the like can be resultantly eliminated.

Title: Flip flop circuit
Inventor: TAMEGAYA YUKIO
IPC: H03K19/094
Filed: 1988-04-27
Abstract: PURPOSE:To prevent an intermediate value from being generated at the output even when a clock signal is changed simultaneously with a change of an input signal by setting the logical threshold of a third NAND circuit to be lower than those of a first and a second NAND circuits. CONSTITUTION:The logical threshold of a NAND circuit 5 is set lower than NAND circuits 3 and 4. Namely, when a clock phi' rises immediately at the time of the fall of a resetting terminal R', an intermediate value appears at an OR circuit 2 and at this a time, the output of a NAND circuit 4 is changed from '0' to '1' and becomes temporarily the intermediate value. At this time, since the logical threshold value of the NAND circuit 5 is set lower than the NAND circuits 3 and 4, the NAND circuit 5 decides that the intermediate value is '1', and since the clock phi', is '1', the output of the NAND circuit 5 becomes '0'. Consequently, the output of the NAND circuit 4 becomes from the intermediate value to '1' and the output of the NAND circuit 3 becomes the intermediate value to '0'. Thus, even when the clock signal is changed simultaneously at the time of the change of the clock signal, the output of the flip flop circuit does not stay at the intermediate value.

CONSTITUTION:Primary air and a fuel ejected through a blast pipe 9 and a fuel nozzle 12 is supplied as a premixed gas to primary burner ports 16 via a premixed gas passage 13 so as to form a primary combustion flame 21. The primary combustion formed within a primary combustion chamber is conducted at limits of inflammability or higher based on primary air and less than theoretical air amount. Further, unburned components not completely burned and remain within the primary chamber 18 receive the supply of secondary air at secondary burner ports 19 thereby to form a secondary combustion flame 22. Upon this occasion, since the combustion is divided into two stages, that is, primary combustion and secondary combustion, the combustion load is lowered and a slow combustion is carried out. Hence, the amount of nitrogen monoxide generated is remarkably reduced.
