Abstract: PURPOSE:To shorten the holding time after power on without increasing the electric power given to a heater of a heat source for a fixer, by advancing the copy operation in a copy speed corresponding to the fixing temperature even before the fixing temperature reaches the stational state. CONSTITUTION:In a heating fixer 67, a fixing roll 83 is heated by a heater 81, and the surface temperature is detected by a thermistor 85 to keep it constant. After a transfer paper 49 (51) is held between the fixing roll 83 which is heated in this manner and a pressure roll 87 arranged to face the fixing roll 83 and is fixed, the transfer paper is ejected onto a tray 69 through an eject roll 89. By this constitution, when the fixing surface temperature reaches a temperature lower than the control temperature after power on of the copy machine body, the holding time is terminated, and the copy operation is possible in a relatively low speed. Thus, the copy operation is advanced in a copy speed corresponding to the fixing temperature to shorten the holding time after power on without increasing the electric power given to the heater 81.

IPC: B01D59/34
Filed: 1985-01-10
Abstract: PURPOSE:To obtain a simple and inexpensive separating method due to one wavelength two-stage method or two wavelengths two-stage method by applying an excimer laser. CONSTITUTION:After harmonizing a photon beam oscillated in a pulse-shape from an excimer laser 1 with the wavelength equivalent to the excitation level of <235>U by means of a dye laser 2, it is introduced into the inside of a separation chamber 3 and irradiated to a mixed vapor flow 11 of <235>U and <238>U generated from an uranium vapor generator 4. Then the photon beam is reciprocated in plural times in the inside of the separation chamber 3 and the photon is effectively absorbed to <235>U. After allowing <235>U to absorb the fist photon and exciting it to the excitation level from a basic level, the second photon is absorbed and ionized beyond an ionizing level. The ionized <235>U is electrically separated from <238>U and collected. In one wavelength two-stage method, two steps of the excitation and the ionization are performed by using the photon of same wavelength and the photon wherein the wavelength is different in each step of the excitation and the ionization is used in the two wavelengths two-stage method.
