摘要:
A method and apparatus for processing data, with the data processing side performing main control and the print control side including control for saving power. The print control side performs transition of a plurality of power saving states to obtain an optimal power saving state on the basis of transfer of data from the main control side, and the data processing side performs various control operations independently of the transition of the plurality of power saving states.

A memory control unit comprising: a first memory for storing a plurality of text information; a second memory for storing title information to segment those text information stored in the first memory; and control device which reads out the title information in the 2nd memory and the information regarding an empty memory area in the 1st memory and provides the empty area to the location next to the text information which will be changed in the 1st memory. When the empty area in the 1st memory is located behind the text information to be changed, other text information subsequent to that text is shifted to the backward location. When the empty area is located before the text information to be changed, that text is shifted to the forward location.

There is provided a pattern output apparatus to particularly output a dot pattern for use in a typewriter, word processor, computer, etc. This apparatus comprises: a memory in which a plurality of pattern information are stored; a read device for reading out the corresponding pattern information from the memory in accordance with an input code; a decision device for discriminating the state of the pattern information read out by the read device; and a device for forming a new code from the pattern information on the basis of the result of discrimination by the decision device. The portions of the codes which were not used so far for the purpose of the output of patterns in the code system consisting of a limited number of bits are used to output the patterns, so that a number of kinds of patterns stored efficiently in a code table can be efficiently outputted.

In a semiconductor power module, a surge voltage on a power source line of a semiconductor element for electric power control is restrained. A power source terminal PS(NP) is comprised of power source terminals PS(P) and PS(N) which are arranged adjacent each other through an insulative sheet INS1 made of insulative synthetic resin or the like. The power source terminals PS(P) and PS(N) are each formed by a conductive plate and respectively transmit a positive and negative power source potentials. The thickness of the insulative sheet INS1 is 0.5 mm to 1.5 mm, for instance. A reduction is made in a parasitic inductance which is present in the power source line which extends from the power source terminal PS(P) to the power source terminal PS(N) through the semiconductor element for electric power control, thereby suppressing a surge voltage which is developed between the power source terminal PS(P) and the power source terminal PS(N).

In a plate type membrane module in which a number of units, each comprising a membrane supporting plate with corrugated surfaces, and membranes formed on the corrugated surfaces, with permeate passageways between the membrane and the corrugated surfaces, are laminated in such a manner that passageways for a solution to be filtered are formed between the units. The waveforms of the confronted corrugated surfaces of adjacent membrane supporting plates are in same phase with each other. Thereby the pulsation of the solution and accordingly the vibration of the membranes can be effectively prevented, with the result that the membranes are prevented from early fatigue.

A peripheral apparatus, a control method for the peripheral apparatus, a memory medium, and an information processing system, in which performance of a connected host computer is not deteriorated are provided. For this purpose, when a status of the apparatus is a first status, a control mode is switched to the first mode such that in response to a data reading request which is issued from the host computer, when response data has been prepared, the response data is notified, and when the response data is not prepared yet, the fact that a response cannot be made is notified, and when the status of the apparatus is not the first status, the control mode is switched to the second mode such that in response to the data reading request which is issued from the host computer, the absence of the data to be responded is notified.

A data processing apparatus for processing text, words or characters has a key entry device, a memory for saving key data from the key entry device and processing means for sequentially processing the key data stored in the memory. When a same key of the key entry device is continuously depressed, the saving of the key data into the memory is suppressed.
