Title: Method and apparatus for isotope separation
Inventor: SHIODA KAZUNORI
IPC: B01D59/34
Filed: 1986-10-09
Abstract: PURPOSE:To easily increase the separation factor of an isotope, by mounting a pulse power source capable of alternately applying voltage to both positive and negative sides with respect to an electrode in synchronous relation to pulse- like ionizing laser. CONSTITUTION:Pulse-like radiation energy beam is allowed to irradiate the vapor stream 5 fromed by evaporating a substance containing plural kinds of isotopes under heating to form a specific ionized isotope. The vapor stream containing said ionized isotope is introduced between electrodes 6, 7 arranged in parallel to separate and recover said stream. The pulse positive voltage synchronous to the irradiation time of the radiation energy beam is applied to a recovery electrode to recover the specific ionized isotope. Since negative voltage is applied between the electrodes 6, 7 during a time other than the irradiation time of the radiation energy beam, the impurity ionized isotope contained in the vapor stream is attracted to the electrode on the side opposite to the recovery electrode and separated. As a result, the separation factor of an isotope is enhanced and, in the separation operation of uranium isotopes, high purity conc. uranium can be obtained.

Title: Microcomputer
Inventor: ITO SAKAE
IPC: G06F9/24
Filed: 1985-10-25
Abstract: PURPOSE:To improve the using efficiency of an EPROM by providing a writing mode register which stores the control switching information to decide whether the writing is carried out to the EPROM from outside or the writing is performed under the control of a microcomputer. CONSTITUTION:When a writing mode register 1 indicates that the writing is carried out under the control of a microcomputer, the connection of the address and data buses is cut off to the external circuits. Then both buses are connected to the output of a CPU 12 and the CPU 12 outputs an address showing an address to be written to a memory cell 10 containing an EPROM to the address bus. Then the CPU 12 outputs the data to be written to the cell 10 to the data bus. Thus the writing is possible to the EPROM with execution of an instruction carried out by the microcomputer itself. As a result, the EPROM can be used for purposes excluding a program memory, therefore the using efficiency of the EPROM is improved.
