摘要： An electronic apparatus includes a controller having an interface part communicating with an external host apparatus and a status register group, and having a plurality of functional units communicating with the host apparatus via the interface part, respectively. The status register group includes operable status registers corresponding to the functional units respectively and indicating whether or not the corresponding functional units are in an operable state, and processing status registers corresponding to the functional units respectively and indicating whether or not the corresponding functional units are in a Function-Being-Processed State. When a command received from the host apparatus is provided for any one of the functional units, the controller transfers the command to the functional unit. In the case of a read command for the status register group, the controller transmits a status of the status register group to the host apparatus as a response.

摘要： A flash memory system is disclosed. The flash memory system includes a flash memory comprising more than one physical block and more than one page, where each page can be in an enabled state, a blank state or a disabled state. In use, a merge control section reads data on an enabled page from a predetermined physical block using a read section, and writes the data onto a blank page using a write section, thereby copying the data on the enabled page onto the blank page. A merge control section then disables the enabled page using a page-disabling section. When the copying of the data from all the enabled pages in the predetermined physical block is finished, the merge control section collectively erases all the data in the physical block using an erase section.

摘要： A low-pass filter of over-sampling type oversamples an input digital audio signal T1 and filters and removes the low frequency components of the produced aliasing noise. A spectrum analyzer circuit calculates the spectrum intensity of a predetermined band of an output signal from the low-pass filter. An expanded signal generating circuit generates an expanded signal having frequency components of the output signal from the low-pass filter. A level control circuit controls the level of the expanded signal according to the spectrum analyzer circuit. An adder adds the level-controlled expanded signal to the output signal from the low-pass filter thereby to generate a digital audio signal T2.

摘要： An ignition system has a spark plug and a positive voltage applying unit. The spark plug includes a central electrode, a porcelain insulator for holding the central electrode, a main metallic shell for holding the porcelain insulator, and a ground electrode electrically connected to the main metallic shell. The positive voltage applying unit applies a positive voltage to the central electrode of the spark plug in comparison with the ground electrode, so that an ignition high voltage is applied between the central electrode and the ground electrode. In the spark plug, a spark discharge gap is formed between the ground electrode and a distal end portion of the central electrode. The ground electrode is positioned so that a rear edge of a mating face opposed to a peripheral side of the central electrode is positioned in the side of the distal end of the central electrode in comparison with an end face of the porcelain insulator.

摘要： In an ink jet recording apparatus having an ink jet head, an ink discharge from the head is executed to maintain and recover the discharge performance thereof. A cap is located opposite to the ink jet head when the maintaining and recovering ink discharge is performed, and receives the discharged ink. A waste ink tank receives ink exhausted from the cap. An ink pump transports ink received by the cap to the waste ink tank by performing idle suction. The number of times the idle suction is performed is variable, and is controlled by a control unit. The idle suction includes idle suction for recovery suction and idle suction for idle discharge. The idle suction for recovery suction is characterized as suction of ink when the cap caps the ink jet head, and the idle suction for idle discharge is characterized as suction of ink when the cap is communicated with atmosphere. The number of times of the idle suction is less for the idle suction for idle discharge than for the idle suction for recovery suction.
