Title: Molten metal pouring device
Inventor: DANNOURA SADAYUKI
IPC: B22D17/12
Filed: 1985-05-23
Granted: 1990-05-07
Abstract: A mill system which receives a flat strip, embosses the outside surface to form flutes and transversely bends the strip to form a curved shape without substantially flattening the flutes. The curved fluted strip is then bent to a circle, welded, given final cylindrical and dimensional forming treatment coated and tensioned wall suface surrounding the vertical bore. By the use of a stationary sleeve which holds solidified pieces during the pouring process, quality of the casting is improved. The invention prevents a shell from intruding into the cavity and minimises the sizes of solidified metal pieces. The metal pouring device facilitates sepn. of the die casting from the cavity.

Granted: 1990-08-11
Abstract: The motor stator consists of three phase armature coils (4,5,6) with hall-effect position sensors, (1,2,3) at their centres. Signals from the sensors are converted by buffer amplifiers (21,22,23) into proportional currents (IH1,IH2,IH3) with each amplifier delivering three output currents of the same magnitude. A detector (110) includes subtractor circuits (31,32,33) where the currents are applied to produce difference signals between them. The difference signals are applied to diodes (41,42,43) of a rectifier-adder circuit (40). Power supplies (101,102,103) energise the armature coils with feedback via an absolute adder (20) to the instruction signal producing circuit (80) for control of motor torque.

Abstract: Metal insulator FET is mfd. on a p-type Si substrate, on which a gate insulating film (12) is formed followed by a poly-Si layer, which is patterned to form a gate electrode (13A). An insulating layer of a doped silicate glass is deposited by a CVD method and is reflowed in inert gas at 1000-1050 deg.C. The reflowed material is etched until the surface of the gate electrode and source/drain regions, except in the vicinity of the gate electrode, are removed, leaving sidewalls (14B) on both sides of the gate electrode, the side edges of which are partially removed. Impurity ions are then implanted, using gate electrode and sidewalls as a mask, forming source (15) and drain (16) regions.

Title: Eeprom device
Inventor: SOWARDS DAVID K
IPC: G11C7/14
Filed: 1990-04-26
Granted: 1998-12-01
Abstract: An EEPROM memory device having dual EEPROM transistor blocks for storing a charge and a current mirror for determining the difference in charge between the EEPROM transistor blocks. During a write operation, one EEPROM transistor block is charged while the other block is discharged. During a read operation, the current mirror attempts to supply equal current to each of the EEPROM transistor blocks. However, because each block has a different charge, more current will be forced through one leg of the current mirror. This results in a voltage difference across the legs of the current mirror which can be read by a voltage sensor.

Title: Exhaust gas purifier
Inventor: LEE HONG-SOB
IPC: F01N3/04
Filed: 1990-05-29
Granted: 1992-03-31
Abstract: The apparatus purifys the exhaust gas by passing the  exhaust gas through water. The apparatus comprises a water flow pipe  (17) for sucking the water of the water tank (2) through a plurality of inlet holes (20) and also spouting the engine exhaust gas into the water tank, and a screw (26) for forcefully discharging the  water of the water flow pipe into the water tank. If the  water  of  the water flow pipe is forcefully discharged into the water tank,  the water of the water tank is sucked in the water flow  pipe  through the inlet holes. So the water gets circulated in the pipe and tank by the screw. The apparatus enhances the purifying efficiency.
