    • There is a case where, in the individual tank number checking processing, usually it is determined that individual tank number agreement can not be confirmed due to a collision of response signals from two tanks. However, due to individual differences among main body side control circuit threshold values and the like, there may be a case that an agreement of the individual tank numbers is confirmed. In response to this, the tank that has the individual tank number whose agreement could be confirmed is put in a sleep state, and because a control code is sent, the other tank designated with color ID is able to return its individual tank number, and the main body side control circuit detects its individual tank number. Based on this it is possible to determine that multiple ink tanks with the same color ID are mounted.

    • A method of creating a power pin model of an LSI having appropriate analysis accuracy in consideration of information on positions within the LSI is provided. A divided cell size decision unit automatically decides a divided cell size of the LSI from power supply circuit network wire information, transistor structure information, analysis frequency information, size information, and element arrangement information of the LSI as well as from a semiconductor integrated circuit entire power pin model. A model creation unit allocates a model of an active section and a model of an internal capacitance section, including the positional information, within the LSI to the cells at an appropriate proportion, and a model coupling unit couples the models in each cell to create a power pin model of the LSI. Here, the size of each divided cell is determined to be electrically sufficiently smaller than a wavelength corresponding to an upper limit analysis frequency derived from power supply circuit network wire information, transistor structure information, and analysis frequency information.

    • An ink jet cartridge including a case, in which the bottom portion where an ink jet recording head is disposed projects, and a lid for covering the top surface thereof. In an ink containing chamber defined by the these case and the lid, there is provided an absorber. The lid is configured so that ribs provided directly over the projecting bottom are higher than the other ribs, and so that the lid can be used for different types of cartridge. In a black cartridge, the pertinent ribs perform the function of effectively bringing the absorber into pressure contact with an ink introducing section. In a color cartridge, the pertinent ribs perform the function of restraining the height of the top surface of the absorber disposed on the projecting bottom portion to a position lower than that of the top surface of each of the other absorbers.
