Title: Developing device
Inventor: TAJIMA HATSUO
IPC: G03G15/09
Filed: 1987-10-07
Abstract: PURPOSE:To prevent a developer from deteriorating and excessive triboelectrification from being caused by arranging a magnetic pole which faces an opening part closer to a magnetic member than the center of the angle that the contact part of a control member and the magnetic member contains so as to reduce the control force to the developer in a downstream side. CONSTITUTION:The magnetic member 10 is arranged in a developer container 4 and the position of the magnetic member 10 is set in the magnetic field area of one of two poles of a magnet roll 3, i.e. a magnetic pole 3a which is directed to the inside of the developer container 4 and on the upstream side of a develop ing sleeve 2 as compared with the maximum magnetic force line position of the magnetic pole 3a. Thus, the magnetic member 10 is arranged on the entrance side of the developer container, so control force operates on the developer here, so control force to the developer further on a downstream side is reducible. Consequently, the developer is prevented from deteriorating owing to partially intense control by the control member 5 and excessive triboelectrification is precluded.

Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory in which a logical potential can be written easily and quickly into a storage node of a memory cell. SOLUTION: The semiconductor memory is provided with a circuit 1 for switching the bit line potential VBL of a DRAM among a power supply potential Vcc, an intermediate potential Vcc/2 and a ground potential GND. The bit line potential VBL is normally Vcc/2. Vcc or GND is applied to all bit lines through an equalizer in special write mode and a desired word line is pulled up to 'H' level before the Vcc or GND is written in the storage node of all memory cells connected with that word line. Vcc or GND may also be written in the storage node of a memory cell replaced with a redundant memory cell.

Abstract: PURPOSE:To obtain the wound core having excellent magnetic characteristics by a method wherein a wound core, consisting of an amorphous magnetic alloy thin plate, is heated up in uniform temperature distribution, and an annealing is performed in a short period. CONSTITUTION:A rectangular wound core 11 is formed by winding a narrow- stripped amorphous magnetic alloy thin plate 12. When said wound core 11 is going to be formed, the amorphous magnetic alloy thin plate 12 is divided for every prescribed number of turns of winding, and a plurality of rectangular divided layers, two divided layers 11a and 11b for example, with which the wound core 11 is divided in the direction of lamination thickness, are formed. On the wound core 11, the divided layers 11a and 11b are separated at a yoke on which a transformer coil 14 is not wound around, the upper yoke for example, and an aperture part 13 is formed between the above-mentioned two layers. Exciting coils 15 and 15 are connected to a high frequency AC power source 17 by a circuit changing switch 16, and a high frequency current is run on the exciting voltage using a voltage regulator 19. An annealing process is performed by generating heat on each divided layer itself by the loss generated by the above-mentioned excitation.

Abstract: PURPOSE: To miniaturize the robot using a motor by detecting a rotational direction/amount of a rotor by a phase and period of a driving coil output voltage waveform in non-excitation condition of a drive coil at teaching time, obtaining the present value of a rotor position, and driving the motor by a difference from a position command value. CONSTITUTION: At the time of teaching, a contact 52 is opened by a switching circuit 50, to connect a contact 56. In this condition, a motor 16 is forced to rotate. In this way, voltage is induced in a drive coil. In a waveform shaping circuit 54, based on its output waveform, a rotational direction of a rotor is obtained, to output pulses Pu, Pd at each fixed rotational angle. By these pulses Pu, Pd, addition or subtraction is performed by a counter 22 and stored in a memory 24. In this way, the present value D of a rotor position is always stored in the memory 24. When the rotor is placed in a prescribed position to operate a coordinate input means 30, this coordinate is stored in the memory 24 and the counter 22. After ending teaching, the motor 16 is driven by a difference between a new position command value E and the stored value.
