Title: Manufacturing thin film transistor
Inventor: MEI PING
IPC: H01L21/266
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To resolve parasitic capacitance between a source electrode and pixel and feed-through voltage, greatly reduce variations of an element size between cells and performance, and reduce overall size of an element. SOLUTION: Radiant filter islands 112 are formed on a semiconductor substrate by the back side lithography. The radiant filter islands 112 permit a light at a wavelength in the lithography to pass through but reflect or do not permit a laser wavelength to pass through. By the laser-assisted doping method, a dopant is implanted in a source and drain regions 132, 134 to self-aligningly form the two regions. Then a source and drain electrodes are formed on the two regions, hence the overlap of the source electrode and the drain electrode with the gate region disappears, and a parasitic capacitance and a feed-type voltage can be reduced.

Title: Prime mover with permanent magnet
Inventor: TANAKA KENJI
IPC: H02K53/00
Filed: 1985-12-28
Abstract: PURPOSE:To eliminate energy from an exterior by temporarily or always interrupting the line of magnetic force emitted from two or more permanent magnets by an interrupting substance to generate an energy. CONSTITUTION:When a substance 3 for interrupting the line of magnetic force is inserted between two permanent magnets 1 and 2, the magnets 1 and 2 do not affect each other. When the substance 3 is removed from between the magnets 1 and 2 by any method, one magnet 2 starts moving by repelling force between the magnets 1 and 2. When the magnet 2 moves to a predetermined position, the magnet 2 tends to return to the original position because of the engine structure using a cranking motion. At this time, when the substance 3 is inserted again between the magnets 1 and 2, the magnet 2 is returned to the original position. Then, the similar operation is performed to continue rotating a flywheel 5.
