A page printer with an internal CPU, interrupt controller, and DMAC has a DMA stopping circuit in the DMAC, the function of which is to stop a DMA transfer in response to a DMA stop signal and restart it in response to a DMA restart signal. The DMA signal is generated by the interrupt controller when it receives certain interrupt requests, such as communication interrupt requests, enabling the CPU to service these requests promptly. The DMA restart signal is generated at the end of the interrupt service routine. This arrangement permits DMA transfers to be performed in burst mode, stopping only when urgent interrupt service is required. Burst-mode DMA improves the speed of operation of the printer.
摘要:
A cooling system including a cooling module which has a heat transfer plate that is exposed to a flow of coolant and is elastically biased toward a circuit component on a printed circuit board for transferring heat dissipated by the component to the coolant. A series of projections are provided on the heat transfer plate for producing turbulence in the flow of coolant. Alternatively, a cylindrical tubular plate is mounted on the heat transfer plate for increasing the surface area in contact with the flow of coolant.

A method of the preparation of an improved high-density sintered alloy composed mainly or iron and up to 50 wt. % of copper, in which boron is added in an amount of no less than 0.03% to suppress or limit the copper growth phenomenon during sintering. The alloys prepared by the present method undergo less dimensional changes during sintering and are thus of a very high density as compared with the conventional alloys of the same type.

A signal transfer device includes an interface and a read and write circuit. The interface has a posted write data protocol and transfers data to a memory control device that controls access to a shared memory. If a write request for writing data to the shared memory via the interface is issued, the read and write circuit acquires a write address from the write request, and puts a read request for reading data from the write address on standby until a transfer amount of write data exceeds a total size of buffers on a signal transfer path to the shared memory.

An air conditioning control apparatus for controlling an air conditioner in a room which accommodates a computer, includes obtaining repetitively a detected value of a total power consumption of the computer and the air conditioner and a detected value of a air temperature at the air inlet, storing the obtained values into a memory, determining an approximate expression representing a relation between the total power consumption and the air temperature on the basis of the values stored into the memory, determining a value of the air temperature corresponding to the lowest value of the total power consumption, by using the calculated approximate expression, and controlling the air conditioner so that the air temperature become equal the calculated air temperature.
