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.

An information processing apparatus having a work suspend/resume function which allows operator to use a main memory shared by different processings even when work suspension information is saved therein. A system for allowing a same operational environment as that set up in one information processing apparatus to be easily implemented in another information processing apparatus. A main memory used by a CPU for execution of processings has a function for storing information concerning the state of the information processing apparatus prevailing at a time point when execution of a given processing is suspended by a CPU for allowing the suspended processing to be performed in continuation later on. When the suspension state information has already been stored in the main memory by a former user, the suspension state information is transferred to a removable nonvolatile storage device so that the CPU can perform other processing than the suspended one by using the main memory. The transfer of the suspension state information is performed by the CPU.
摘要:
A workpiece comprising an aggregation body of platelike articles, sheet-like whose fibers have been opened by rolling, stick-like articles formed by finely tearing them from a single plate, flake-like articles, strand-like articles or the like is inserted between an upper heat plate 12 and a lower heat plate 13 of a heating press apparatus 10. A spacer 14 for surrounding the workpiece and determining the final thickness of the product is arranged on one or both of the heat plates before or after the insertion of the workpiece 11. The workpiece is compressed by the upper heat plate 12 and the lower heat plate 13 to thereby form an air tight compartment made of the upper heat plate 12, the lower the plate 13 and the spacer 14, and containing the workpiece. The air tight compartment is decompressed by vacuum for a predetermined period, then steam or heated gas is jetted onto the workpiece in the compressed air tight compartment. Preferably, a decompressing is ensured again after jetting the steam or the heated gas, resulting in the final thermocompressed aggregation product.

摘要:
An image-forming apparatus for exposing a photosensitive material with image light. An optical modulation device is provided such that the intensity of image light made incident from one side of an optical modulator is modulated in correspondence with the intensity of the image light made incident from the other side of the optical modulator as well as a drive voltage to be applied, and the image light made incident from one side is made emergent from the optical modulator. Since the modulation of the intensity of the image light is effected by the optical modulator, the amount of exposure supplied to a printing paper is controlled in correspondence with the density distribution of the image on a negative film, and an image having appropriate contrast can be reproduced by effective use of the latitude of the printing paper.
