Filed: 1986-12-04
Abstract: PURPOSE:To supply an electrostatically charged developer on a fur brush by a constant amount at the time of voltage application and to prevent a layer of a developer on a developer carrier from becoming irregular in thickness by raising the voltage of a voltage applying means between the developer carrier and a means for electrostatic charging gradually to a prescribed voltage. CONSTITUTION:The developer 28 is conveyed through the rotation of the fur brush 30 to a position opposite to a developing roller 29 to coat the surface of the developing roller 29 with the electrostatically charged developer 28. At this time, the developer 28 which is supplied by a proper amount is charged electrostatically and further uniformly the rotation of the fur brush 30 to the positive polarity by friction against the surface of the developing roller 29. Then a 2nd DC high voltage power source 46 raises the voltage gradually to the prescribed voltage between the developing roller 29 and fur brush 30. Consequently, the electrostatically charged developer 28 on the fur brush 30 is supplied by the constant amount onto the developing roller 30 even at the time of the voltage application and thereafter to coat the surface of the developing roller 29 with the electrostatically charged developer 28 uniformly. Consequently, only the normally charged developer 28 is used for development and an excellent image is obtained.

Title: Streak tube
Inventor: KINOSHITA KATSUYUKI
IPC: H01J31/50
Filed: 1989-11-08
Abstract: PURPOSE:To improve time resolution by adjusting the travel distance of a photoelectron emitted at a different initial rate from a photoelectric surface. CONSTITUTION:A photoelectron incident via a light entrance window 1 and generated due to image formation on a photoelectric surface is accelerated toward the first reflector 4. In this case, a photoelectron A emitted at a high initial rate from the photoelectric surface 2 of high energy is reflected after coming nearer the electrode 4 due to backward electric field formed therewith. Also, a photoelectron B of less energy is reflected at a higher rate than the photoelectron A. The photoelectron reflected with the backward electric field formed with the electrode 4 then travels toward the second reflector 5, and is similarly subjected to a repellent force. Similar to the case of the electrode 4, the photoelectron A is reflected with the electrode 5 after coming near thereto. In the course of approaching a sweep electrode 3, therefore, the photoelectron A of high energy travels a longer distance than the photoelectron B. Consequently, the irregularity of time for arriving at the sweep electrode 3 is reduced, and all photoelectrons arrive at the electrode 3 approximately uniformly.

Abstract: PURPOSE:To enable setting of high output voltage by setting an upper limit on the operation result of basic waveform thereby eliminating limit of multiplier and divisor. CONSTITUTION:At step 11, basic waveform data are read out from a ROM5 based on a phase angle theta. At step 12, the data are multiplied by a voltage indication variable V according to an output voltage. An example is shown for the case where the output indication voltage V=1.25V. When the output indication voltage V=1.25, the upper limit is confirmed at step 13 and the process goes to step 14 if the upper limit is exceeded then values other than the upper limit are limited to the upper limit. Step 14 is bypassed if the upper limit is not exceeded. By such arrangement, operation results can be obtained. At step 15, the operation results are converted into time, which is then employed for control of an output port 7 through a timer 6 and the like.
