Title: Moving picture signal compression device and method
Inventor: SUZUKI TERUHIKO
IPC: H04N19/85
Filed: 2001-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent an error due to mismatching between a local decoder of an MPEG system moving picture signal compressor and a compression moving picture signal expander. SOLUTION: The mismatching error can be prevented by applying inverse orthogonal transform to a block of a transform coefficient in orthogonal transform after applying pre-processing to the block. Sum of the transform coefficients in the block is obtained and the parity (odd or even number) of the sum is discriminated. When the sum parity is an even number, the parity of one of the transform coefficients in the block is inverted to generate a parity inversion transform coefficient. Thus, the sum parity is an odd number. Then inverse orthogonal transform is applied to blocks of transform coefficients including the parity inversion transform coefficient.

Title: Fuel cell system
Inventor: SAITO KAZUO
IPC: H01M8/04
Filed: 2001-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent the generation of flooding in a fuel cell system, and suppress fuel consumption worsening when the stoichiometric amount of air to fuel is increased in a low load as a flooding preventing countermeasure. SOLUTION: When a water recovery operation state is detected, an anode circulation flow rate is corrected to a high flow rate, and the stoichiometric amount of air to fuel gas supplied to a fuel cell is increased. Even if the pressure of the supply gas is increased according to water recovery operation, the generation of flooding can be suppressed, the operation of the fuel cell system is stabilized, and pressure balance of an anode and a cathode is always equally kept. Since the flooding is eliminated only by the increasing correction of the anode circulation flow rate, operation is continued without wastefully consuming fuel.
