Filed: 1993-05-18
Abstract: PURPOSE:To suppress the degradation of electrostatic charging performance and to excellently maintain image quality by providing a carrying part for replenishment fetching the carrier developer of a developer replenishing part in a developing tank and a carrying part for discharging a developer in a developing tank and driving these carrying parts with the same means. CONSTITUTION:Projecting parts 16b and 16c are formed in the parts of the developing tank 16 corresponding to both end parts of a developer replenishing/discharging shaft 22, the replenishing screw 22a as the carrying part for replenishing is formed on one end part of the developer replenishing/discharging shaft 22 and the discharge screw 22b as the carrying part for discharging is formed on the other end part, so that the developer is carried in the direction of A by the rotation of the developer replenishing/discharging shaft 22 and the degraded carrier in the developing tank 16 is exchanged with a fresh carrier. Since the developer is replenished/discharged by a quantity corresponding to the drive of the carrying part for replenishing 22a and the carrying part for discharging 22b by the developer replenishing/discharging shaft 22, even if the quantity of the developer in the developing tank 16 is fluctuated, the developer is surely discharged to exchange the developer in the developing tank 16. Thus, the ratio of the exchange of the degraded developer for the fresh developer can be controlled.

IPC: B23Q1/00
Filed: 1979-09-12
Abstract: PURPOSE:To improve cutting performance as a whole by a method wherein a bed is given structure wherein ribs are arranged in an angled form aslant to the direction perpendicular to the longitudinal side of the bed so as to increase the rigidness against the torsion around the axis Y of the bed. CONSTITUTION:Ribs 21-23 in angled form, arranged aslant to a bed, are fitted to the side (a) of the surface of the bed whereon a saddle moves slidably and to the side (b) of the part whereto a column is fitted. With this constitution, only the deformation within the faces of ribs takes place when the torsional torque round the axis Y caused by the column acts thereon, and thus high rigidness is attained for the bed.

Filed: 1990-05-09
Abstract: PURPOSE:To prevent the occurrence of hunting phenomenon of an elevation hydraulic system by outputting a signal, by means of which a given increase constant is added to a control current signal, to an electromagnetic flow rate control valve for a specified time when a load pressure signal at a point of time when lowering operation of a working machine lever is started exceeds a given relief pressure. CONSTITUTION:When a mast device is raised and it is detected that a load pressure signal from an oil pressure sensor 3 exceeds a relief pressure at the final point of the stroke of an elevation cylinder, a preset initial control current signal value is outputted to an electromagnetic flow rate control valve 4. Thereafter, a signal by means of which a preset increase constant is added to the control current signal is outputted for a specified time. After a lapse of the specified time, a control current signal calculated from a load pressure signal from the oil pressure sensor 3 and an operation signal from a working machine lever 1 is outputted to the electromagnetic flow rate control valve 4. This method prevents the occurrence of hunting phenomenon of an elevation hydraulic system occurring when lowering operation after the pressure of the elevation hydraulic system attains a relief pressure is effected.

IPC: G06F3/06
Filed: 1981-07-29
Abstract: PURPOSE:To control plural driving devices with one controller, by calculating the length from the current position of a head to an objective position in terms of the number of clocks synchronized with the rotation of a medium to detect the objective position. CONSTITUTION:When the end signal of positioning to an objective truck is inputted from one driving device 2, a controller 1 reads a sector address on a disc and calculates the difference between this sector address and an objective sector address, which is stored in a memory 14 for microprocessor, in a microprocessor 13 and calculates this difference in terms of the number of clocks synchronized with the rotation of the disc by the output of a frequency dividing circuit 4. This number of clocks is set to a down counter 3 of the driving device 2 to instruct the detection of the position of the objective sector. Until the driving device 2 issues a detection signal 9 of the objective position, the controller 1 executes the service for another driving device. Independently of the controller 1, the driving device 2 divides a clock 16, which is generated from a rotation controlling circuit 5, by the frequency dividing circuit 4 and counts down contents of the counter 3 and detects the objective position when they become 0.
