Title: Image forming device
Inventor: YOSHIDA TAKAYUKI
IPC: G03G15/20
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent image quality deterioration caused by toner scattering, etc., in a fixing device. SOLUTION: The surface potential of the heating roll 13 of the fixing device 12 is detected by a potential detector 24. A power source 22 impresses a bias voltage on the roll 13. This power source 22 compares the surface potential detected by the detector 24 with the output voltage of its own, and increases/ decreases the output voltage in a direction where a deviation is eliminated. By this bias voltage, toner particles Tp on a recording paper P uniformly receive electrostatic force by potential by electrification of the rolls 13 and 14, and are pressed to the paper P in a perpendicular direction. Consequently, the toner particles do not easily move on the recording paper by the bias voltage, so that the image quality deterioration caused by the scattering, etc., in the case of fixing can be prevented.

IPC: F02D41/34
Filed: 1984-03-31
Abstract: PURPOSE:To operate an internal-combustion engine smoothly even when the opening of a throttle valve is large, by detecting the maximum value and the minimum value of the frequency of the signals produced by a Karman-vortex flow meter while the engine is rotated by a certain angle, and determining the injection quantity of fuel from a logical frequency. CONSTITUTION:A Karman-vortex flow meter 100 produces a signal having a frequency corresponding to the quantity of intake air drawn to an internal-combustion engine. A means 101 detects the maximum value and the minimum value of the frequency of the signals produced by the flow meter 100 while the engine is rotated a predetermined angle. An arithmetic means 102 calculates the difference of the maximum and minimum values detected by the means 101, while a judging means 103 judges whether the difference detected by the arithmetic means 102 is greater than a predetermined value or not. A mean-value calculating means 104 calculates the mean value of the maximum value and the minimum value obtained by the detecting means 101. In case that judgement is made by the means 103 that the above-mentioned difference is greater than said predetermined value, a means 107 calculates the injection quantity of fuel on the basis of a logical frequency stored in a memory 105. In case that said difference is smaller than the predetermined value, an injection means 108 injects fuel on the basis of the mean value obtained by the calculating means 104.

Abstract: PURPOSE:To eliminate unnecessary spurious signals due to the reflection, by devising the shape of the remotest end of an outer ridge of a bus bar, taking the length in the surface wave propagation direction and forming ruggedness at a right angle in the direction of propagation. CONSTITUTION:The bus bar 5 is formed for the inner ridge almost along the envelope of weighting, and the outer ridge is formed with a projection 8 with a lambda/4 of step difference in the direction of surface waves. Enlarged view of a part B surrounded with a dotted circle is shown below. The remotest end of the outer ridge of the bus bar is taken as a shape as shown in figure, allowing to eliminate the reflection of the surface waves due to the difference between the acoustic impedance of the region where an electrode exists and not. That is, there is a difference of path by lambda/2 in the reflection waves as shown in arrows 11 and 12, then the phase difference is 180 deg. and they are cancelled with each other. Since the reflecting waves are cancelled with each other at the ruggedness, the unnecessary spurious signals are all eliminated, the lengths (l) and l') of the ruggedness are equal and less than lambda.
