20090198463AUTOMATIC ANALZYER - An object of the present invention is to automatically investigate factors in complicated uncertainty, particularly from the view point of reagents and samples which are subject to quality change and prone to affect the measurement quality. To accomplish the above object, quality control samples having a plurality of concentration levels are measured to calculate the average, coefficient of variation, standard deviation, and other numerical values. When quality control samples having n (n>=2) different concentration levels are measured, the present invention provides the method to presume the factors in uncertainty, the factors being specific to each of 308-06-2009

20080232614SOUND AMPLIFIER WITH SPEAKER - An instrument amplifier includes an amplifier circuit for amplifying a sound signal input from an electric guitar. A main speaker emits sound according to the sound signal being amplified. A CD player plays back an audio signal from an audio CD. Side speakers for playback emits audio sound according to the audio signal being played back. A speaker box contains the main speaker and the side speakers in one space. In one embodiment, the speaker box includes a rear panel for closing a space behind the main speaker and the side speakers. Furthermore, an output mode key is settable in a first mode by external operation, the first mode being for controlling the playback speaker to emit sound according to the sound signal. The side speakers are disposed beside one another, for stereo sound emission of the audio sound.09-25-2008

20090087702FUEL CELL SYSTEM - A fuel cell system and method of controlling a fuel cell system capable of preventing deterioration in performance when the system reinitiates a normal operation from an idle stop state. For a predetermined time after reinitiating the supply of fuel gas and oxidant gas from the idle stop state, discharge of off-gas occurs and the cessation of fuel gas and oxidant gas supply is prohibited.04-02-2009
20090197129FUEL CELL SYSTEM - A fuel cell system can be initiated in shorter time while minimizing the deterioration of a fuel cell. The fuel cell system includes a fuel cell stack having a fuel electrode, an oxidizer electrode and an electrolyte membrane disposed there between, the fuel cell producing electricity by an electrochemical reaction of a fuel gas and an oxidizer gas, which are supplied to the fuel electrode and the oxidizer electrode, respectively; a fuel gas supplying device for supplying the fuel gas to the fuel cell stack; an oxidizer gas supplying device for supplying the oxidizer gas to the fuel cell stack; a current controlling device for extracting a current from the fuel cell stack; and a voltage sensor disposed in at least two of the fuel cell stacks. A controller controls the current controlling device such that a minimum voltage, which is obtained from the voltage sensor after a fuel gas is supplied to the fuel electrode without supplying the oxidizer gas to the oxidizer electrode at the time of initiating, becomes zero volts or more. Then, the oxidizer gas is supplied to the oxidizer to start producing electricity.08-06-2009
