Abstract: For a paper feed operation, it is determined whether printing is being performed. When printing is not performed, the paper feed is enabled even in the on-line state, thereby omitting a vain key operation. Further, a line feed key and a paper discharge key are set as the same key and a paper discharge stop function is provided, thereby enabling the line feed of a large amount to be executed by a smaller number of key strokes.

Abstract: An information processing system that has a memory for storing information, a control memory for storing control information on the information stored in the memory, and a control unit for writing a signal representing "under writing", "under reading" or "under transfer" into the control memory while information is written into, read from or transferred from the memory.

Abstract: 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).

Abstract: A changeover control unit of an information processing system transmits data to either one of at least two input buffers such as a printer buffer, key buffer and the like, the data being transmitted via a single signal line or functionally a single signal line connecting the at least two input buffers and the control section of the machine. The data includes a communication control data for controlling the control section and the buffers, or an information processing data from the key buffer. The change-over control unit judges the code of the data, decides whether the data is for a printer buffer, key buffer or the like, and changes over the receiving positions for the data.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An electropic typewriter includes a changing unit for changing margin positions; a storage device for storing hot zone position information; and a deriving unit responsive to the change of the margin positions caused by the changing unit for deriving a new hot zone so as to modify the hot zone position stored in the storage device.

Abstract: A display apparatus for displaying a dot pattern comprises a memory in which a plurality of character patterns are stored, a second memory in which second character patterns different from predetermined character patterns among the character patterns stored in the memory are stored, and a display device which can display both the character pattern stored in the memory and the second character pattern stored in the second memory. The second character pattern may be a bold, underlined, superscript, or subscript character pattern. When a desired character is displayed as a bold character, for example, the bold character is formed either by reading out the bold character from the second memory in which the bold character has preliminarily been stored or by changing the desired character to the bold character by a character pattern changing circuit.

Abstract: 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.
