IPC: G03G15/09
Filed: 1986-03-04
Abstract: PURPOSE:To reduce the load of a device by providing the device with a moving means for opposing the magnetic pole of a developing device which is not used for development to a nap regulating member and receding the magnetic pole of the other developing device from the part opposed to the nap regulating member. CONSTITUTION:The moving means 30 for a magnet roller 13 is constituted of a lever 31, a spring 32 and a solenoid 33. At the time of non-driving of the solenoid 33, the magnetic pole N1 of the magnet roller 13 is opposed to a photosensitive drum 1 and a magnetic pole N3 is receded to a position moved from the opposite part to the nap regulating member 19 by theta2 (40 deg.) in the counterclockwise direction. At the time of the solenoid 33 is driven, the magnetic pole N3 is opposed to the member 19 and an intermediate part between the magnetic pole N1 and a magnetic pole S1 is opposed to the opposite part to the drum 1. Since the moving means moves only the magnetic pole and load applied to the moving means is slight, the moving device can be sufficiently driven only by a small driving source, and is inexpensive.

Title: Sliding nozzle device which is notched at corner part
Inventor: TAIRA TOSHIMITSU
IPC: B22D41/28
Filed: 1981-03-30
Abstract: PURPOSE:To provide a titled device which prevents generation of negative pressure in the anticipated negative pressure or vortex generating zones (corner parts) which are the opening ends below a stationary plate or a sliding plate and to regulate the flow of molten metal by notching the parts which are the upper parts of said zones.

Title: Control device for air cooled condenser
Inventor: TAKANO TOSHIO
IPC: F28B11/00
Filed: 1982-03-25
Abstract: PURPOSE:To improve the following characteristic of the titled device to meet a sudden  load change in a process having a constant bypass, by a method wherein the blade  angle of each of cooling fans is operated to generate a feedforward signal, the ON- OFF amount of a fan number control system is analogized and the amount of operation of the device is varied precedently. CONSTITUTION:When a load changes suddenly, the change is detected as the amount of  variation of a turbine inlet steam flow rate 16 and the amount of variation of a turbine  bypass steam flow rate 17 before it is detected from the pressure 19 of a condenser.  Then the change is operated by a feedforward signal operation section B and the result  of operation is converted into the equivalent of the amount of operation of the blade  angle control device to thereby increase or decrease the amount of operation directly.  Further, with the variation of the load, a fresh target value operated by a final target  value setting section A is adjusted finely by a pressure adjust meter D in consideration  of the result of control. Thus, when the amount of operation reaches its upper or lower  limit, the cooling fans 21 are started or stopped in sequence by the operation of a cooling fan number precedence element introducing section C and at the same time, the  amount of operation is increased or decreased directly as a correcting part of the feedforward signal by making the load change equivalent to the amount of operation for  the change in the fan number, as a precedence element.
