摘要:
The present invention is one for providing an apparatus and a method which make it possible to remove a foreign object or matter such as scale attached on an inner surface of a pipe easily for a short period of time by means of simple equipment and manner, and constituted as follows. Specifically, a holder (11) is attached onto an end of a pipe (P), an abrasion assisting member (16) fixed to a tip end of a support arm (15) is inserted into the pipe (P) by use of the holder (11) and stopped at an area (A) where oxide scale (S) is generated in a large amount. Then abrasive is sent with pressure into the pipe (P) by a blast device (14), and thus a flow rate of the abrasive in the scale-abraded area (A) is increased to abrade and remove the oxide scale (S) securely. Moreover, if required, a spiral groove (17) is formed on an outer circumference of the abrasion assisting member (16) to increase centrifugal force of the abrasive.
摘要:
A VLSIC page printer controller includes an instruction processor which responds to a host computer and a printer video processor for accessing data from memory under the control of the instruction processor and serializing data for transfer to a printer through a video port. An I/O interface interconnects the printer controller with an I/O bus to which is connected a host computer, memory devices, and other peripheral devices. An internal memory interface connects the printer controller to memory, and the printer video processor is provided with direct memory access (DMA). Data and instruction caches and an instruction ROM are provided on-chip. A RISC instruction processing unit includes as an integral part thereof the special function, circuits of orthogonal rotator, bit/byte mirror, and pixel modification.
