Title: Touch panel inputting device
Inventor: MAEDA TOSHIFUMI
IPC: H01H13/14
Filed: 1999-06-29
Granted: 2001-06-23
Abstract: The present invention provides a touch panel inputting device to prevent malfunction even when this whole device 1 is inclined and to input a pressurizing position with a light pressurizing operating force even for finger input. Transparent insulating fluid 11 is sealed between two transparent plates 2 and 3 of conductive layers 4 and 5 oppositely installed to improve the transmissivity. Also, the opposite face of at least one transparent plate 3 is formed as a projecting and recessing face 3a, and the surface of the conductive layer 5 covering the opposite face is formed as a projecting and recessing face. When the whole device is inclined, the insulating fluid 11 sinks, and the upper conductive layers 4 and 5 come in contact with each other, and only the recessing parts of one conductive layer 5 come in contact. Thus, the deterioration of a contact resistance can be prevented, and erroneous recognition that a pressuring operation is performed can be prevented. At the time of the pressurizing operation, the insulating fluid 11 is saved to the recessed parts of the conductive layer 5 without being interposed between the conductive layers 4 and 5 so that the exact contact can be realized even with the light pressurizing operation, and the pressurized position can be inputted.

IPC: A01G27/00
Filed: 1999-09-30
Granted: 2000-07-11
Abstract: This is an automatic water-supply equipment for an airtight flowerpot. The airlock technology allows the water in the flowerpot reservoir to be automatically supplied to the pot according to the plant's needs. The water can also be controlled at a certain level for supplying an appropriate amount of water such that frequent manual watering is not needed. The equipment is mainly constructed with an integrated and airtight inner and outer bodies between which a water reservoir and a water supplying space are formed. The bottom of the inner body is equipped with an upper and lower controlling hole per the set height. When water level of the water supplying space is lower than the upper hole, water from the reservoir will be supplied through the lower hole until the water level is higher than the upper hole. The upper hole is then blocked by the water, which forms a vacuum effect so the water in the reservoir will not output. The equipment is a unique controlling method without complicated parts and mechanisms. The goal of automatic water supply, closing and controlling water supply amount within measure is reached. It has a practical application value.

Granted: 2001-09-11
Abstract: The invention provides an apparatus for depositing semiconducting, insulating, and particularly, high dielectric constant (HDC) material, such as barium strontium titanate, on a substrate through reactive sputtering. The apparatus comprises a physical vapor deposition chamber having an asymmetric bipolar pulsed direct current power source supplying a first bias to a target and a second bias to the substrate support member in the chamber. The pulsed direct current power source supplies an electrical waveform comprising a negative deposition voltage that attracts the argon ions to cause sputtering from the target and a reverse small positive neutralization voltage to cause charge neutralization of the target that eliminates arcing and micro-arcing on the target surface. Preferably, the first bias is synchronized with the second bias for the deposition period and the neutralization period. A floating-ground shield surrounds the processing region between the target and the substrate. A first gas inlet introduces a gas for the plasma through the top portion of the chamber, and a second gas inlet introduces a reaction gas adjacent the substrate surface to react with the sputtered material to form the HDC film on the substrate.

Title: Apparatus and method using phase detection to equalize power from multiple power sources
Inventor: JANSEN ARIAN M
IPC: H02M3/155
Filed: 2000-03-04
Granted: 2002-10-21
Abstract: An apparatus and a method may use variable-frequency power sources for supplying power to a load. The apparatus and method use phase detection in order to automatically and substantially equalize the currents supplied to a load by each of the variable-frequency power sources, and to cancel a ripple component of the input current drawn by the apparatus. First and second power sources supply power to the load. The power sources have a similar relationship between their respective variable switching frequencies and the power that they supply to the load. First and second switching frequencies of, respectively, the first and second power sources are locked to one another using phase detection to substantially equalize the power supplied to the load by each power source. The apparatus and method are advantageously utilized to provide a power factor correction front-end for a switch-mode power supply. Power sources with non-linear and/or inverse relationships between power supplied and switching frequency can be used. In alternate embodiments power from series power sources is equalized by equalizing voltages supplied by each power source to a load.

Granted: 2002-12-01
Abstract: The present invention discloses a manufacturing method for back channel etching (BCE) type of thin film transistor (TFT) array and the thin film transistors formed therewith, which uses less amount of masks. In this method, it only needs five masks to form the TFT array of BCE type, which is less than the number of masks normally required by the typical TFT manufacturing process, that is, with at least six masks. The five masks required in the process according to the present invention individually are: the first mask for the pattern of gate bus; the second bus for the patterns of islands and S/D data lines; the third mask for the patterns of data lines, thin film transistor (TFT) channels, and Cst; the fourth mask for the patterns of passivation layer; and, the fifth mask for the patterns on the conductive electrode layer. The thin film transistors (TFT) manufactured by the innovative method according to the present invention provides preferred contact resistance between the source/drain (S/D) metal and n<SP>+</SP> amorphous silicon layer. The preferred contact resistance is achieved by the immediate deposition process on the source/drain (S/D) metal film after the deposition of the n<SP>+</SP> amorphous silicon layer, thus it can greatly reduce or eliminate any exposure to the chemical pollutants of the interface, and the self-oxidation. The innovative method according to the present invention further provides the advantages that, the second metal layer will shield the island structure of the thin film transistor (TFT) from the damage of the plasma, and from the remaining photoresist etchant, so as to improve the structural reliability of the thin film transistor (TFT) array.
