A single information processing device capable of configuring an information system that maintains matching between information retained by a self device and information retained by a partner device in a way that links up a plurality of information processing devices with each other, has a storage unit including a memory cell retaining a predetermined quantity of information and a comparing unit that compares the information retained by the memory cell at the present with information written afresh to the memory cell, an extraction unit extracting the information written afresh to the memory cell about which the comparing unit judges that the information retained at the present is different from the information written afresh, and a transmitting unit transmitting the extracted information to the partner device linking up with the self device.

Charging time of a capacitor is shortened while avoiding erroneous firing due to distortion of a power supply voltage and sustaining an inrush current at a constant level. In the charge control method of a capacitor in a thyristor converter comprising a thyristor for rectifying an AC voltage, a CPU delivering an on/off control signal to a thyristor driver for driving the thyristor, a voltage detection sensor for measuring the AC voltage and the capacitor charging voltage, and the capacitor connected with a DC circuit, the AC voltage and the capacitor charging voltage are measured by means of the voltage detection sensor, differential voltage between the firing phase voltage of the thyristor and the capacitor charging voltage is determined, and the thyristor is fired only when the firing phase voltage of the thyristor becomes lower than a specified voltage determined from the differential voltage.

An asynchronous access system for a computer system includes processing modules performing processes, at least one shared system memory module, and a system bus connecting the processing modules and the shared system memory module. Each of the processing modules includes a processor, a plurality of buffers coupled to the processor and to the system bus, and a controlling unit for writing data from the plurality of processors into the shared system memory module. Data is written into the shared system memory module by a processor generating write instructions to write data via the plurality of buffers and the system bus. The controlling unit controls the writing such that one writing instruction writes data into a plurality of buffers, then transfers the data to the shared system memory module via the system bus, with another writing instruction writing additional data into another plurality of buffers and transferring the additional data to the shared system memory module.

A message control system for a data communication system in the form of a loosely coupled multiprocessing system, in which a plurality of processing modules having a memory unit are coupled to each other via a system bus. In this message control system, a memory unit, within each processing module, includes a data processing part which is in software running on a central processing unit within its own processing module, a descriptor which manages address and data length information of a storage region for a message in the form of a chain, and a buffer which decomposes and stores a transmitting message. A connection unit within each processing module includes logical transmitting ports and a logical receiving port.

摘要:
An extraction circuit is connected to an input path of an output amplifier. When the power is turned on, the extraction circuit extracts current on the basis of a difference between the normal rise of the supply voltage and a delayed supply voltage. Therefore, a steep rise in the input of the output amplifier when the power is turned on can be removed.

When a player character performs an act tendency (boom) triggering act, the act number counters are updated for each non-player character associated with the boom triggering act. The value of each act number counter is periodically added to an act tendency value for each non-player character. After an act tendency value reaches an upper limit, the corresponding non-player character performs an act in response to the act tendency triggering act performed by the player character. The act of each non-player character is changed in accordance with the acts performed by the player character in the game world, which provides the player with a fresh feeling that the act performed by the player character set a trend in the game world.

There is provided a PWM inverter capable of preventing a phase error from occurring in generating a PWM signal even in the case where a carrier wave frequency is not sufficiently higher than a signal wave frequency. A PWM signal generating section (2) includes a phase adjusting section (11) configured to advance a phase of the signal wave by adding, to a signal wave, a delay component of the PWM signal with respect to the signal wave, the phase delay component being involved by digital control. Furthermore, in a case where the carrier wave frequency is changed, the phase delay component with respect to the signal wave is updated in synchronism with the timing of change of the carrier wave frequency.

A power amplifier drives a load connected to a first output terminal and a second output terminal. When generation of over-current is detected by the current detection section, the output amplifier control section is controlled to stop the operation of the output amplifier section, and when a voltage greater than or equal to said set value is detected by said voltage detection section, the stopped operation of said output amplifier section is maintained even though generation of the over-current is not detected at the current detection section. When the terminal voltage detection section detects a terminal voltage greater than or equal to a predetermined voltage, over-current at the current detection section is suppressed.
