Inventor: UNE EISUKE
IPC: H04N9/64
Filed: 2002-05-13
Abstract: <P>PROBLEM TO BE SOLVED: To correct a skin color of an picked-up image to an ideal skin color.  <P>SOLUTION: One picked-up image is divided into a plurality of areas, for example, 7×7 areas, and a color of each area is discriminated. Data related to the color of an area judged to be a skin color are used to calculate a gain of white balance for obtaining the ideal skin color. A variation in luminance value of each area is used to discriminate whether the picked-up image has ruggedness or not. The number of areas which have ruggedness and are judged to be a skin color determines whether the calculated gain of white balance should be used or not. This method is applicable for a video camera which reproduces the ideal skin color by white balance adjustment.  <P>COPYRIGHT: (C)2004,JPO

Abstract: <P>PROBLEM TO BE SOLVED: To prevent global warming as an urgent matter by a combination engine, in which the exhaust temperature of a gas turbine is brought nearly to -273°C, water and steam are aggregated with cryogenic exhaust combination gas as nucleus, and the aggregates are separately collected by converting the turbine into the internal engine drive of zero-exhaust- combustion gas reduced at 1/10 electricity rate.  <P>SOLUTION: The temperature of exhaust combustion gas is brought nearly to -273°C by conducting endlessly combustion heat-exchange by a combustor-cum-heat-exchanger of the gas-turbine combination engine. Almost the total heat quantity of compressed air at least -273°C is collected to make a heat-collection amount of about twice the amount of an existing boiler. The increase process of (amount of combustion-gas heat quantity power- generation)+(amount of combustion-gas mass power-generation)=(amount of idea power generation of 220-530 times the existing gas turbine) is run by the combination engine, in which friction loss between the gravitational power of 1700 times water and turbine is greatly reduced by electromagnetic heating turbine blades ring-molded in each stage. The combination engine is simply structured having minimum heat-quantity consumption, and a water content is aggregated with the cryogenic combustion gas as nucleus and separated into hailstones and waterdrops. Thus, zero-combustion-gaseous exhaust such as CO2 is accomplished by this combustion engine.  <P>COPYRIGHT: (C)2004,JPO

A thermally-actuating plate 5 is connected with and fixed to the inner face of the container 2, and the movable contact point 6 is arranged open-close free with the stationary contact point 9. In the motor protective device 1, because a thermally-actuating plate fixing position 2A of the container 2 is flattened and deformed, the pressure between the contact points is adjusted, and the operated temperature is calibrated. A displacement part 2B which is made easier to deform by making the plate thickness thinner than that of its peripheral part is installed in the vicinity of the thermally- actuated plate fixing position. The operating temperature of the thermally- actuated plate can be reduced because the displacement part 2B of the container is deformed in the smashed direction if it is exposed to a high pressure state. Therefore, the current supply can be cut off under a high pressure.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for deciding position of conversion head on disk surface, and disk drive
Inventor: GREENBERG RICHARD
IPC: G11B21/00
Filed: 2002-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a servo address encoding to store more information with fewer bits. SOLUTION: A servo address is encoded a disk drive system 100 having at least one disk 102 for storing data. A servo address associated with a sector in a track, or cylinder, on a surface of a disk and comprised of a sector number, a track number, and in multiple disk systems, a head number is encoded into an encoded servo address. Encoding the servo address saves disk storage space because the encoded servo address uses fewer bits than a conventional servo address while still enabling the disk drive system to locate positions on the disk.
