Abstract: PURPOSE:To realize a complete connection network among plural devices with out increasing the number of hardware regarding a complete connection type data transferring device. CONSTITUTION:A transfer processing part 16 of plural processors 10 rearranges data on a buffer corresponding to the data transfer and transmission destination, transmits the data by time-division, and performs access to a main storage according to information received from a network 12. The network 12 rearranges the data received by time-division from the plural processors 10, and transmits the data to each transmission destination. For example, when the network 12 is constituted of a cross bar network, the (n) processors 10 are connected with the network 12, and proper device number 0, 1, 2,..., n-1 is assigned to each processor 10, the transfer processing part 16 transmits transmission data for the arbitrary transmission destination processor by shifting only by its own device number (i), and the network 12 executes the connection to the processor 10 made to the device number k=i+j from the processor 10 of the device (i) at a timing (j).

Abstract: PURPOSE:To provide a buffer memory controller which has high universal applicability and can facilitate the input/output of data subject to the signals of all standards by providing several pairs of data transfer control circuits and buffer memories in parallel to each other. CONSTITUTION:A clock pulse generator 46 is controlled by the synchronizing signal supplied from a computer main body 1 or an external device 3 and produces the clock pulses. A counter register 45 stores the memory address of the data stored in a buffer memory 42 and to be read and written secures synchronization with the clock pulse of the generator 46 to control the largest count value through the main body 1 or the device 3. A data transfer controller (a) 41 controls the input/output of data between the main body 1 and the memory 42, and a data transfer controller (b) 44 refers to the value of the register 45 as a memory address and reads and writes the data stored in the memory 42.

Abstract: PURPOSE:To prevent occurrence of come-off or crack of a heat insulator due to an abrupt rise of the temperature of the inner surface of a combustion chamber during initial combustion of rocket propellent by continuously decreasing the variance of heat insulator particles in a mother metal material from the thicknesswise center part to the inner and outer surfaces. CONSTITUTION:The center part of a rocket engine combustion chamber is formed of a composite metal material layer in which heat insulator particles 2 are uniformly distributed in a mother metal material 1 by a greatest variance. Further, intermediate parts 4, 5 formed on the inner and outer surfaces of the center part 3, are formed of a composite metal material layer in which the heat insulator particles 2 are uniformly dispersed in the metal mother material 1 by a variance which is smaller than that of the center part 3. Further, an inner surface part 6 formed on the inner surface of the inner intermediate part 4, and an outer surface part 7 formed on the outer surface of the outer intermediate part 5 are formed of a metal layer made of the pure mother metal material in which no heat insulator particles 2 are contained. That is, the variance of the heat insulator particles 2 in the mother metal material is reduced from the widthwise center part toward the inner and outer surfaces.

Abstract: PURPOSE:To provide an excellent heat radiation characteristic without decrease in the withstand voltage characteristic by forming the outer surface of a discharge container of the surface area where a high heat radiation material is exposed and the surface area where a conductive material for restraining electric potential change is exposed. CONSTITUTION:The heat conducted to a discharge container 3 is radiated to the outer space through a high heat radiation material 12 set on the outer surface of the container 3. The outer surface of the container 3, at this time, is formed in combination of the surface area where the material 12 is exposed and the surface area where a conductive material 13 is exposed. By selecting the distribution of both surface areas, the potential width at the surface of the material 12 can be controlled to a small value. As a result, when electrons of electrode plasma generated outside of a shield case 1 flow to the outer surface of the container 3 through pores 2 of the case 1, the electrons are restrained from concentrating at one position, thereby preventing decrease in withstand voltage characteristic between the case 1 and the container 3.

Abstract: PURPOSE:To readily select the object to be corrected without requiring special knowledge by dividing the object into elements at its display and taking the element as an object when the result discriminating the right or wrong of the selection is correct. CONSTITUTION:When an operator selects the menu BR, for example, the video display is changed. As the display includes a part to be corrected, the selected operation is judged to be correctly performed. An object should be branched into OL and OR and the object OR is designed to include objects ORR and ORL. In this case, when the operator selects the menu BR again, the object ORR is selected but a part to be corrected (object ORL) is not included so that the selected operation is judged to be incorrectly performed. In this case, by selecting the R one-rank higher than the menus BR and BL, the upper object OR including the object ORR is displayed again on the video display device. When the menu BL is selected, the object ORL is properly selected.
