Title: Toner for pressure fixing
Inventor: KATAGIRI YOSHIMICHI
IPC: G03G9/087
Filed: 1989-07-07
Abstract: PURPOSE:To allow pressure fixing with high electrostatic chargeability by forming the toner in which polyester polyol having the mol. wt. of the value in a specific range is used as a toner binder for pressure fixing and which consists of a compd. consisting of C, H, O. CONSTITUTION:The toner constituting the two-component developer or one- component developer of electrophotography consists of the polyester polyol which is expressed by formula and has 1,000 to 100,000 mol.wt. as its essential constituting component. In the formula, R1, R2 are an alkyl group or phenyl group. This polyester polyol is used as the binder for pressure fixing. While the binder for pressure fixing is inferior in the ease of plastic deformation to polyethylene wax, etc., of a low mol. wt., the binder hardly generates floccula tion, such as blocking and caking, during the preservation of the toner or in a toner replenishing hopper. The good fixability is, therefore, assured by setting the line pressure in a fixing part slightly higher. The toner for pressure fixing having the high electrostatic chargeability is thus formed.

Title: Liquid level detector
Inventor: ISHIMA KAZUMI
IPC: G01F23/24
Filed: 1982-10-10
Abstract: PURPOSE:To perform a display or an alarm detecting the timing at which the quantity of ink is below the specified value by comparing a voltage of a detection electrode in an ink with a reference level after the value is detected through a high resistance and amplified. CONSTITUTION:When a pair of detection electrodes are placed into an ink, a resistance of several 10kOMEGA is obtained between electrodes. When the value of Rx is 50kOMEGA, the OSC output 2V, R1 950kOMEGA and R2 and R3 1kOMEGA respectively, the potential at the point B is 1V by i2=2/(R2+R3)=1mA and the potnetial at the point A 1.05V by i1=(2-1)V/(R1+Rx)=1muA. Therefore, the voltage applied probably ranges from 50 to 100mV even when the resistance of the ink varies by about 10% depending on the temperature. But as the Rx becomes infinite when the ink runs out, the drop in the voltage due to the R1 becomes zero, the potnetial at the pont A turns to 2V. After amplified with A1 and rectified with (Rect), the voltage is compared with a reference voltage Vref by COM to enable the checking to see if ink runs out. This can be notified of by a display or an alarm.
