Title: Dynamic level deciding circuit
Inventor: OMOTANI YOSHIRO
IPC: H04N19/51
Filed: 1988-06-24
Abstract: PURPOSE:To accurately decide a dynamic level even when a noise, etc., mix in a picture signal by obtaining the difference in the picture signal with a frame memory and a subtracter, converting the absolute value of the difference into the gradation of a numeric level, and making the output into a movement deciding signal. CONSTITUTION:The picture signal inputted to an input terminal 1 is delayed for one frame by a frame memory 2, and the difference between the signal at a current point and the signal delayed for one frame is obtained by a subtracter 3. While the difference becomes zero when a picture is under a static state, the difference becomes an existing value when the picture is under a dynamic state. Further, the dynamic quantity of the picture is determined by obtaining the absolute value of difference amplitude by an absolute value circuit 4. A maximum circuit 7 makes the maximum level of each input signal into the dynamic quantity of a signal d0 at the current point and makes the dynamic quantity into a dynamic level signal from an output terminal 9. Consequently, the influence of the noise can be reduced by outputting the maximum level of each level of a near picture element even when a spike-shaped noise mixes in the picture signal.

Title: Solder for superconductor
Inventor: KOIZUMI MISAO
IPC: H01R4/02
Filed: 1981-09-30
Abstract: PURPOSE:To increase the specific resistance of solder considerably by adding a specific content of In to a coventional Sn-Ag alloy as solder for superconductors. CONSTITUTION:In the case of twisting or weaving plural pieces of superconductive wires, the superconductive wires are bound by means of solder in order to improve the stability among the superconductive wires and the mechanical strength over the entire part. As the solder to be used in this case, In is added at >=0.1% to a conventional Sn-5% Ag alloy and the alloy is used as an Sn-Ag- In alloy. Since such solder has considerably large specific electric resistance as compared to conventional solder and decreases the binding current induced among the superconductive wires, binding losses are decreased and the efficiency of the pulse magnets produced by said wires is improved.

IPC: G03G15/08
Filed: 1995-05-29
Abstract: PURPOSE: To provide an image forming device which maintains a desired gap between the surface of a developing sleeve and the surface of a photoreceptor by means of a simple structure, presses a developer layer to the photoreceptor at uniform pressure and therefore obtains a satisfactory image having very little irregular-image-density. CONSTITUTION: A drive transmission means which transmits rotation drive to the developing sleeve 5 is provided with a drive gear 19, whose shaft is held by the main body of the image forming device at both its ends, and a follower gear 20, whose shaft is held by a developing device at both its ends and which transmits the driving force of the drive gear 19 to a developer carrier. The gears 19 and 20 are disposed so that the engaging parts of the gears 19 and 20 are positioned near the middle of the developing sleeve 5 in the longitudinal direction. Thus, because the driving force of the gear prevents the developing sleeve 5 from slanting to the photoreceptive drum, the image having very little irregular-image-density can be obtained.

Filed: 1987-06-23
Abstract: PURPOSE:To effectively remove a gel layer and a cake layer and to prevent a decrease in the flow rate of the permeated liq. by making the pressure on the permeated liq. side of an ultrafilter membrane higher than the pressure of a raw liq. during continuous filtration, and washing the membrane with a washing soln. from the permeated liq. side. CONSTITUTION:The raw liq. in a raw liq. tank 5 is circulated through the ultrafilter membrane device 1 by a raw liq. circulating pump 3 through pipelines 7 and 8. The liq. permeated through the ultrafilter membrane is recovered in a receiver 6 from a pipeline 13 while controlling the flow rate by an automatic opening and closing valve 2.
