Title: Fixing device
Inventor: OGURI SHINICHI
IPC: B05C1/02
Filed: 1986-09-01
Abstract: PURPOSE:To prevent a release agent from overflowing from an oil pan, and also, to always uniformly apply the release agent to a fixing roller without being influenced by a variation of a liquid level height and an inclination of an image forming device body, by providing a release agent impregnating member such as felt, etc., in the oil pan. CONSTITUTION:An impregnating member 4 consisting of felt, etc., which has been placed in an oil pan P so as to surround the lower face of a draw roller 1 is impregnated with silicone oil O in the oil pan P, and always contact the outside peripheral surface of the lower part of the draw roller 1. Accordingly, as for the silicone oil, its greater part contacts the draw roller 1 in a state that the impregnating member 4 has been impregnated therewith, therefore, even if the draw roller 1 and an applying roller 2 rotate in order to apply the silicone oil to a fixing roller, it does not occur that the silicone oil is drawn up abundantly onto the draw roller 1 due to a flow resistance by the impregnating member 4, and an overflow of the oil does not occur. Also, a variation of a liquid level height h3 of the silicone oil, which follows up a rotation of both the rollers 1, 2 does not occur, therefore, the quantity of application to the fixing roller 3 can always be kept constant.

Abstract: PURPOSE:To determine a holding electric energy of a secondary battery line during the continuation of a backup by selecting a redundant number of secon dary battery lines after a set battery having redundant secondary battery line'> is charged to measure electric energy discharged when the battery line selected is discharged. CONSTITUTION:A set battery B1 has secondary battery cell lines A1-An connected in parallel and has a capacity enough to accomplish a backup for a specified time even if any one of the battery lines A1-An is missed. Switches 1l-Sn are changed over to the position of a charging circuit C and an output voltage of an input power source E is matched with the circuit C and the set battery B1 is charged fully through resistances R1-Rn. Then, for example, a switch S-1 is turned to the position of a discharge capacity measuring circuit J to let charged current of a cell line A-1 flow to the circuit J for the measuring of a holding electric energy. Thereafter, the switch S-1 is turned back to the original position to recharge the cell line A-1 through a resistance R-1. Likewise, the switches S-2 to S-n are changed over to measure holding electric energy of the cell lines A-2 to A-n. Thus, the holding electric energy of the set battery B1 is determined from the total sum of the holding electric energy.

The mixture is sent by the pump 1-d to a reaction tube 3 kept at a constant pressure and temperature with a pressure adjustor 7 and a thermostatic vessel 4 to oxidize organic matters in the sample water (a) by potassium persulfate. Thereafter, the heated mixed liquid is mixed with helium d-2 in a carbon dioxide extractor 8 and furthermore, carbon dioxide formed is separated while being cooled by a cooling water 9 to be extracted into helium. Water in helium is separated with a water separator 10 and sent to a detector 11, with which the concentration of organic carbon is measured from the concentration of carbon dioxide in helium.

IPC: B65H9/14
Filed: 1984-10-02
Abstract: PURPOSE:To correct erroneous transport of original sheet likely to occur at the time of switching-back by allowing the sheet to run against a feed roller and thereby forming a loop. CONSTITUTION:In separation stage, a separation drive motor is turned on to separate only the undermost lying one of the original pages in a bundle, and when it proceeds in a sheet bus Ia and a sheet sensor S1 senses the leading edge of the sheet, a separation loop timer is started and, after completion, said separation drive motor is turned off to allow the leading edge of the sheet to run against the nip part of feed rollers 6, 6a, to be followed by stop of the sheet when such a condition is attained that a loop corresponding to a certain amount is formed. This can correct eventual skew likely to occur at the time of separation to contribute to prevention of jamming as well as to saving recording material.

Filed: 1984-10-04
Abstract: PURPOSE:To prevent stoppage of a copying machine during copying operations, by making alarming display when the number of copies to be taken is larger than the number of remaining transfer papers. CONSTITUTION:The number of remaining transfer papers is detected in such a way that, when a tray lower limit sensor SIG2 which detects whether a tray is lowered or not is turned on, a remaining quantity counter is set at zero and the number of pulses generated until tray motor lifting is turned off after the sensor SIG2 is turned off is counted. Then whether the mode is multi-job mode or not is discriminated and, when the multi-job mode is set, the prearranged number is checked and data are set in a set counter corresponding to the prearranged number. Thereafter, values of the remaining number counter an total counter are compared with each other at a control section 12 and, when the number of remaining transfer papers is larger than the number of copes to be taken, the copying operations are continued. When the former is smaller than the latter, display of 'want of paper' is displayed through a display section 13.
