Title: Electrophotographic device
Inventor: WATANABE NORIYUKI
IPC: G03G21/00
Filed: 1989-07-28
Abstract: PURPOSE:To correspond the content of an overwrite counter to a toner residual all the time by storing the content of the overwrite counter in a nonvolatile memory and setting the reading to contents stored in the nonvolatile memory when a power source is again turned on. CONSTITUTION:When toner in a developing unit becomes less, a toner end sensor 28 detects that, whereby the overwrite counter CN counts the number of subsequently printed sheets to store its reading in the nonolatile memory 31. When the power source is turned on, the contents stored in the nonvolatile memory 31 are set to the overwrite counter CN, which continuously counts the number of subsequently printed sheets from the set content. At this time, the counted content of the counter CN is also stored in the nonvolatile memory 31. Thus, the content of the overwrite counter CN can be corresponded to a toner residual regardless of whether the power source is turned on or off.

Abstract: PROBLEM TO BE SOLVED: To accurately measure the displacement of an object to be measured from a datum surface to a displaced surface by providing a displacement correcting means which corrects the deviation value of the object from a prescribed position in the direction of displacement. SOLUTION: When N pieces of coordinate sequences (Xt, Zt) (t=1 to N) are inputted to a displacement correcting section 62 from a displacement detecting circuit 31, the section 62 calls displacement data Z(j) containing the deviation value of an object to be measured from a prescribed position from the deviation value correction table of a deviation value storing section 61 and obtains coordinate data, Zt-Z(j), indicating the real displacement of the object by subtracting the data Z(j) from displacement data Zt and correcting the obtained data with respect to the movement of a scanning means 4 in the direction of displacement.  When the N pieces of coordinate sequences (Xt, Zt) (t=1 to N) are inputted to a scanning position correcting section 72, the section 72 calls the Xr value corresponding to each scanning position data Xt from the scanning position correction table of a position storing section 71 and replaces each scanning position data Xt with each position data Xr. The deviation value of an object from a prescribed scanning position in the scanning direction of a scanning position detecting means 5 is corrected by using N pieces of coordinate data (Xr, Zr).

Abstract: PURPOSE:To prevent not only the contamination of a membrane but also the lowering of flux at the reopening time of operation by allowing the transmitted water stored in a head pressure generating means to act on the surface of the membrane on the water transmitting side thereof by water head difference without using push-out water. CONSTITUTION:When a membrane separator is stopped, a water supply pump 11 is stopped and a valve V1 is opened while a valve V2 is closed and a blow valve V4 is opened only for a short time and the valve V2 is closed in a minute when the valve V1 is opened. Whereupon, the residual pressure on a concn. side 3 and the residual pressure in the piping on the upstream side of the pump 11 of a water supply pipe 12 are released and the transmitted water from a head tank 6 acts on the surface of the membrane on the water transmitting side of a membrane 2 by water head difference. As a result, since the suspended substance in the raw water remaining on the concn. side is not pressed to the membrane, the membrane is not contaminated during the stop of the operation of the separator.
