摘要:
In a bus control device including an external interface, internal units, a memory interface, and an internal bus, the memory interface monitors the usage pattern of the internal bus, and in a case where the internal unit is not using the internal bus, a priority processing interval for allowing only the external interface to use the internal bus is set, thereby prohibiting the internal units from using the internal bus during the priority processing interval.

A plurality of fluorescent lamps 30 are in a decentered layout so as to be placed in a peripheral part of an upper space of an environmental test chamber 11 above a sample loading surface 21. The irradiance distribution of light from the fluorescent lamps 30 over the sample loading surface 21 is in the range of ±25% relative to the irradiance at the center of the sample loading surface 21.

A muffler of an internal combustion engine is characterized in that a muffler of an internal combustion engine having a muffler main body connected to a rear end of an exhaust pipe of the internal combustion engine, a tail pipe extended from a rear end surface of the muffler main body, and a tail cover covering an outer periphery of the tail pipe includes a partition wall compartmentalizing a space formed between the tail pipe and the tail cover into at least two or more spaces.

Methods and compositions for blocking exocytosis by inhibition of proteins that regulate exocytosis, such as N-ethylmaleimide Sensitive Factor (NSF), are provided. The compositions include multidomain fusion peptides containing a domain that causes the fusion peptide to cross the cellular membrane (e.g. a domain from the TAT protein of HIV) and a domain that inhibits NSF (e.g. a domain of NSF). Administration of the fusion peptide promotes anticoagulation, attenuates thrombosis, and decreases heart attack severity.

A misfire detection apparatus of an internal combustion engine for detecting combustion or a misfire of an air fuel mixture in the internal combustion engine based on an ion current generated at the combustion time of the air fuel mixture. The misfire detection apparatus includes ion current detection means and misfire determination means. The ion current detection means detects the ion current responsive to the amount of ions occurring in a cylinder just after combustion of the air fuel mixture in the cylinder in the internal combustion engine. The misfire determination means calculates a predetermined function based on the ion current detection value and determines that the condition is combustion when the magnitude exceeds a threshold value.

The purpose of the present invention is to propose a machine tool having a linear guide device with new construction enabling exchange of a linear guide by easy work.With regard to a machine tool having linear guide devices 1 each of which has a base 11, guide rails 12 mounted on the base 11, linear guides 2 movably mounted on the guide rails 12, and jack-up mechanism comprising a saddle 9 (moving body) movably supported by the guide rails 12 through the linear guides and jack-up bolts 5 arranged between the base 11 and the saddle, the linear guides are fixed to the saddle through a fixing member, the fixation of the linear guides to the saddle is released by operating the fixing member, and gaps 8 are formed between the saddle and the linear guides by the jack-up mechanism arranged between the base and the saddle (moving body), whereby the linear guides can be exchanged.
摘要:
A value of the number of prefetch words is preset by a master device 50 in a number of prefetch words setting section 14 of a slave device 10. The number of prefetch words refers to the number of data units sequentially receivable by the master device 50 at a time from the slave device 10. When the slave device 10 receives a read transfer request from the master device 50, a prefetch control section 13 reads from a memory 15 contiguous data units having a quantity equal to the value of the number of prefetch words, and then writes the contiguous data units into a data buffer 12. A bus interface 11 transmits the contiguous data units stored in the data buffer 12 to the master device 50.
摘要:
In a memory interface, a buffer is composed of a plurality of blocks corresponding to respective corresponding banks in a multibank memory. A bank determiner stores an input memory access parameter into a corresponding block. A buffer controller performs an output control of the buffer so that memory access parameters are output from the buffer in order of the respective corresponding banks in the multibank memory. A row address comparator compares row addresses of consecutively output memory access parameters for access to the same bank. When accesses are consecutively performed with respect to the same bank and the same row, a command generator skips generating a precharge command to be issued after memory access for a preceding memory access parameter.
摘要:
The data transfer device for transferring data between a system bus and a local memory having a frame buffer region and a general region includes an interface section and a data processor. The interface section generates a transfer parameter for accessing one of the frame buffer region and the general region based on control data for controlling data transfer sent from the system bus and outputs the generated transfer parameter, in addition to transferring data to/from the system bus. The data processor generates an address of data to be transferred in the local memory according to the transfer parameter, and transfers data to/from the local memory using the generated address, in addition to transferring data to/from the interface section.
