摘要:
A device for purifying the exhaust gas of an internal combustion engine using a particulate filter arranged in the exhaust system. The trapped particulates are oxidized on the particulate filter, and the particulate filter has a trapping wall for trapping the particulates. The trapping wall has a first trapping surface and a second trapping surface. The device reverses the exhaust gas upstream side and the exhaust gas downstream side of the particulate filter so that the first trapping surface and the second trapping surface are used alternately to trap the particulates.

An information processor including a keyboard, a main body and a display device. The keyboard is provided with plural infrared-ray emission elements which are located at different positions so as to face in different directions, and an identifying code setting switch for setting the identification code of the keyboard into an infrared-ray signal transmitted from each infrared-ray emission element. The main body includes plural infrared-ray receiving elements which are located at different positions so as to face in different directions, an identifying code setting switch for setting the identification code of the keyboard, and a keyboard controller for judging whether the same identification code as set by the identification code setting switch is contained in the infrared-ray signal which is received by any one of the infrared-ray receiving elements.

A preform for metal matrix composite material comprising: inorganic particles, small-diameter inorganic fibers, and large-diameter inorganic fibers. An average particle diameter of the inorganic particles is 1 to 50 &mgr;m. An average fiber diameter of the small-diameter inorganic fibers is 2 to 5 &mgr;m, and an average fiber length of the small-diameter inorganic fibers is 10 to 200 &mgr;m. An average fiber diameter of the large-diameter inorganic fibers is 4 to 20 &mgr;m, and an average fiber length of the large-diameter inorganic fibers is 10 to 200 &mgr;m. The small-diameter inorganic fibers catch and disperse the inorganic particles in a process of forming a formed body, and the large-diameter inorganic fibers create voids in cooperation with the small-diameter inorganic fibers in the process of forming the formed body.

An information processing apparatus is provided which is capable of carrying out the higher memory access. The information processing apparatus includes a memory unit of a synchronous DRAM device which serves to output data synchronously with the supplied clock signal, and a control unit for controlling the access to the memory unit in accordance with an instruction issued from a CPU. The clock signal which is to be supplied to the memory unit is outputted from the control unit. The clock signal which has been outputted from the control unit is supplied to the memory unit and also is pulled back to the control unit. The control unit fetches therein the data, which has been outputted from the storage unit, at the timing which is determined on the basis of the pulled back clock signal. As a result, the control unit reduces the difference between a delay of the data which is outputted from the control unit and a delay of the clock signal which is used to determine the timing at which the data is fetched therein.

Parameters representing types of machines to be connected to a network, connection types thereof to the network, and operation modes thereof in the network system are set from an information processing apparatus. The obtained parameters are written as parameter files on a recording medium. In each network machine, a network system is automatically constructed by referencing the files. Consequently, the parameter setting operations for the installation of the machine are simplified and there is achieved automation of operations in each network machine.
