Title: Power feeding system
Inventor: FUKUMOTO SHINICHI
IPC: H04M19/08
Filed: 1988-06-15
Abstract: PURPOSE:To receive high-quality signals for which switching noises are not superposed by stopping the output of a switching regulator and using the DC power produced by the discharge of a charging means when an in-house device side is in a receiving state. CONSTITUTION:When a digital line tereminating device (DSU) 10a side is in a transmitting state, a changeover switch 60a selects the power voltage 3' outputted from a DC/DC converter 40a and supplies the selected voltage 3' to a transmission line terminating section 3. At the same time, the converter 40a supplies a voltage 4' of (supply voltage 3'+alpha) to a battery 50a so as to charge the battery 50a with electricity. When the DSU 10a side is in a receiving state, on the other hand, the terminating section 3 sends a part of received main signals to the switch 60a and converter 40a as a transmission/reception switching signal 2'. In receiving the signal 2', the converter 40a stops the output of the power voltages 3' and 4' and, at the same time, the switch 60a changes over the power supply to the terminating section 3 from the power voltage 3' to the battery 50a. Therefore, no switching noise is superposed.

Filed: 1987-06-16
Abstract: PURPOSE:To improve the compression rate by separating a digital color picture data into a shape data and color information of an area surrounded by the data and compressing the information quantity of data. CONSTITUTION:A picture is divided into areas S1-Sn and colors are assigned to them. If the (n) is nearly 4000, the picture is regarded to be sufficiently of high quality. Moreover, the sectional lines of S1-Sn represent the shape of the picture. That is, the picture data is divided into the shape data and the color data of the areas surrounded by the shape data. The picture data is searched in lateral and longitudinal directions to compare whether or not the color is the same color in a predetermined noise margin and when the same color, bit 0 is set and in case of not the same color, bit 1 is set. Thus, the shape data is expressed by 1 picture element (i)-bit. The color data of the sectioned area is further combined into adjacent areas and coloring is applied an 2-dimensional area.

Abstract: PROBLEM TO BE SOLVED: To obtain a developing device capable of stably guaranteeing the quality of an image over a long term by realizing a developer recovery means making the discharge amount of developer nearly constant with simple constitution and saving trouble in the replacement of developer, especially, in the constitution where a rotary type developing device is not used. SOLUTION: Much of the developer T with which the magnetized area of a magnet 4 is coated is fetched in a developing container 2 by following the rotation of a developing sleeve 3 but one part thereof is leaked out to the outside of the magnetized area and accumulated in the vicinity of a void B. The leaked amount is restricted by a regulating member 6 provided in the container 2, whereby the leaked amount per one rotation of the sleeve 3 is made constant. When the amount of the developer accumulated in the vicinity of the void B becomes equal to or above some extent, the developer is gradually pushed out from the void B, loses the restricting force of magnetic field by the magnet 4 and drops into a recovery container 6 attached to the container 2.
