Title: Electrophotographic photoreceptor, production of electrophotographic photoreceptor, process cartridge and electrophotographic device
Inventor: SOMA TAKAO
IPC: G03G5/00
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic photoreceptor having high durability with which an image of high quality can be obtd. without depending on the use environment by providing the external area of a dispersing means with a circulating means for the producing method of a dispersion liquid for a protective layer and dispersing while circulating the dispersion liquid. SOLUTION: In the production of an electrophotographic photoreceptor having a protective layer with dispersion of a conductive powder in a resin on a photosensitive layer, the dispersion liquid for the protective layer is produced by providing the external area of a dispersing mans 1 with a circulating means 2, and circulating and dispersing the dispersion liquid. Namely, the dispersion liquid is sent to a dispersing means 1 by the circulating means 2 while the returned liquid from the dispersion means 1 is returned to a liquid tank 3. Further, by repeatedly circulating the liquid, the dispersion liquid is obtd. By this method, the coating liquid for the protective layer has uniform dispersion and narrow distribution of particle size, which decreases variance in the dispersion state for dispersion lots.  The electrophotographic photoreceptor produced by this method shows little variance among batches, and good image can be obtd. without depending on the use environment.

Title: Control signal generating circuit
Inventor: NAKAMURA AKIRA
IPC: G06F12/02
Filed: 1993-08-11
Abstract: PURPOSE:To provide the control signal generating circuit which is low-priced and facilitates the change of timing. CONSTITUTION:A control signal reading means 44 applies addresses to address input terminals A0-A15 of a control signal storage means 42 while changing them into the order of addresses one by one based on a clock signal CLK from a control circuit 10. The control signal storage means 42 stores a control signal data column, for which the high and low levels of control signals are previously made correspondent to the binary data of '0' or '1' time sequentially, corresponding to respective control signal output terminals D0-D7 in the order of addresses. According to the changes of address values applied to the address input terminals A0-A15, the control signal storage means 42 outputs the control signal data column, namely, control signals TM1-TM6 respectively from the control signal output terminals D1-D6. Since this circuit is not constituted by combining logical elements, it is low-priced. On the other hand, since the control signal data column stored in the control signal storage means is reloaded, timing can be easily changed. Thus, the mutually synchronized control signals can be generated.

Abstract: PURPOSE:To detect watthours and consumed charges in a plurality of systems with one apparatus by providing a current-signal receiving part for a plurality of systems comprising current transformers which are connected to power lines to be measured and signal converting circuits which convert the detected currents into DCs. CONSTITUTION:A current transformer 3 of a current-signal receiving part 2 in each system is connected to a power line 1 of respective power system to be measured. Then, a current corresponding to the power in the system flows through each current transformer. The current signal is amplified and converted into AC in a signal converting circuit 4. The value is multiplied by, e.g. preset data in a power computing means 5. Thus the consumed electric energy for every system is computed. The consumed electric energy is integrated in an integrated-power computing means 7 with the elapse of time. Watthours are multiplied by a unit rate which is determined beforehand, for example, in a consumed charge counting means 8. Thus the consumed charge is computed. Then, the consumed watthours and the consumed charge are displayed on a display means 9 in digital values. In this watthour meter, the total watthours and the consumed charge of the power system to which each current transformer is connected are displayed.

Filed: 1983-11-25
Abstract: PURPOSE:To flatten frequency characteristics of the total gains by setting the frequency characteristics of amplification gains of respective amplifiers of the high frequency and the intermediate frequency in the amplification frequency band so that the higher the frequency will be, the lower the characteristics will be. CONSTITUTION:A high frequency signal HF from an input terminal is amplified by a high frequency amplifier 20 which is composed of FETs 201 and 202. The amplified output and the output of a local oscillator 14, which has the lower frequency than the receiving frequency of the HF, are mixed with a mixer 13 through an LPF, and an intermediate frequency signal IF, which has the lower frequency than the receiving frequency of the HF, is formed. The IF is amplified by an amplifier 21. The amplifier 21 is composed of two-stage unit amplifiers 211 and 212, and a return amplifier 213. The inclination of the amplification ratios of the amplifiers 20 and 21 is almost equalized, and the amplification ratio with high frequency is enlarged. By selecting the frequency of the local oscillator 14 higher, the upper end and the lower end of the receiving frequency band and the intermediate frequency band are inversed. Thus, the flat amplification characteristics are obtained by using a semiconductor element whose flattening of the frequency characteristics is difficult.
