Title: Image forming device
Inventor: TADA TATSUYA
IPC: G03G15/00
Filed: 1990-11-27
Abstract: PURPOSE:To prevent poor cleaning and the scattering of developer inside this device by recovering deteriorated developer from a developer carrier to a deteriorated developer recovery device by a developer recovery controlling sequence when the developer is excessively stirred in a developing device. CONSTITUTION:When an original consuming very little toner is continuously copied from a point A in the figure, toner concentration hardly changes, so that only the stirring is executed without toner supply. Consequently, succeeding images become the image having thin density because of the charge-up phenomenon of the toner in spite of optimum toner concentration. Therefore, a comparison circuit outputs a high density signal when the output signal of an original density detecting sensor 22 is higher than the output reference value VDENS at the time of reference density previously set, that is, when the density is thick, and a counting circuit allows the deteriorated developer recovery device 23 to act when the number of high density signals outputted in a specified time previously set is equal to or less than a specified number. Thus, the poor cleaning and the scattering inside the device, which occurs when the deteriorated developer on an electrostatic latent image carrier by developing is recovered, are prevented.

Title: Variable attenuator
Inventor: TOKUDA MASAMORI
IPC: H03H11/54
Filed: 1993-12-22
Abstract: PURPOSE:To realize a variable attenuator which is less dependent upon temperature and is superior in temperature characteristic. CONSTITUTION:PIN diodes 6a and 6b forming an attenuating circuit have the conductivity changed by a current Id to attenuate an input signal Si; but since they have negative temperature coefficients, the current Id is increased to narrow the variable range of the degree of attenuation accordingly as the ambient temperature rises. Therefore, an attenuation level set signal Vd applied to PIN diodes 6a and 6b is generated by an attenuation level setting circuit 3 including positive temperature coefficient thermistors 13a to 13c which have positive temperature coefficients and is applied to the attenuating circuit 2. Consequently, the attenuation level setting signal Vd has the level reduced in accordance with the rise of the ambient temperature to cancel the negative temperature coefficients of PIN diodes 6a and 6b. Thus, the degree of attenuation of the attenuating circuit 2 shows an excellent stability against the change of the ambient temperature, and the variable attenuator whose dependence upon temperature is improved as much as possible is realized.
