Abstract: PURPOSE:To avoid a sharing state of a memory space for transfer of data by sharing a low-order address bit which designates a memory address between a main device and an input/output device and at the same time producing a high-order address bit via a control circuit of an input/output circuit. CONSTITUTION:A control circuit 21 of an input/output device 2 transmits the signals A0-A7 of low-order N bits which designate the addresses of a main memory 11 and an input/output memory 25 as well as a read/write signal R/W via an address line 41 and a R/D control line 42 which are connected in common to a DMA controller 22. At the same time, the signals A8-A15 of high-order P bits which designate the address of the memory 11 are sent to an address line 43 via an address latch circuit 23. Furthermore the signals A8-A15 of high-order Q bits which designate the address of the memory 25 are sent to an address line 44 via an address latch circuit 24 respectively. Both memories 11 and 25 are connected to each other via a common data transfer line 45 so that common memory space is not needed for transfer of data between both memories 11 and 25.

Title: Electrode foil for aluminum electrolytic capacitor
Inventor: TEZUKA SHUJI
IPC: H01G9/055
Filed: 1998-06-19
Abstract: PROBLEM TO BE SOLVED: To improve electrostatic capacity per unit area by heating fine particle of at least one kind of metal of Ti, Zr, Hf, Nb or at least one kind of oxide, nitride and carbide of metal to a fusing point of aluminum or higher and a fusing point of fine particle or lower and thereafter injecting and fixing it to a surface of an Al foil. SOLUTION: After fine particle of zirconium oxide and Al fine particle are mixed at the ratio of 4:1 and are heated to 10000 deg.C, they are injected on an Al foil. The foil is subjected to formation treatment to obtain a film withstand voltage of 22V. After it is heated to a fusing point of fine particle or lower, it is injected on an Al foil; then, a surface of an Al foil dissolves by heat of fine particle and thereby fine particle is deposited on an Al foil surface keeping Al and fine particle bonded. Electrostatic capacity per unit area can be remarkably increased by increase of a surface area due to irregularities of the deposited fine particle and high dielectric constant of fine particle. Furthermore, if Al fine particle is mixed as binder, bond strength among fine particle is raised and effect is further improved.
