IPC: C10B21/10
Filed: 1991-03-12
Abstract: PURPOSE:To improve the capability of an actual oven battery temperature in following a change in the target oven battery temperature without impairing the stability of the control system. CONSTITUTION:The finite time settling gain H(z) of a finite time settling element 4, which adjusts the coke oven battery temperature in a finite time following a change in the target oven battery temperature, is determined in advance based on the gains of a feedback integral element 1, a coke oven process element 2 and a feedback proportional element 3 which are the components of the control system. The integral values of a difference between the target oven battery temperature and the actual oven battery temperature in the past, which are assigned to each of the feedback integral element 1, the coke oven process element 2 and the feedback proportional element 3, the present oven battery temperature, the past oven battery temperature and the quantity of heat introduced in the past are multiplied by each gain for each element to obtain numerical values. The quantity of heat introduced to compensate disturbance is determined based on these numerical values. At the addition point 6, the values obtained by multiplying the present target oven battery temperature and the past target oven battery temperature by the finite time settling gain H(z) in the finite time settling element 4 are added to the quantity of heat introduced to compensate disturbance, thereby obtaining the quantity of heat to be introduced to make the actual oven battery temperature coincident with the target oven battery temperature.

Title: Image forming device
Inventor: MARUTA TAKAYUKI
IPC: G03G15/08
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To prevent the sticking of a useless developer to an image carrier, by immediately stopping an electrifying operation and switching a developer into a noncontact state, before the bottom end of the electrifying region of the surface of the image carrier passes through a developing region, so as to stop the application of a developing bias voltage, at the time of making an emergency stop. SOLUTION: When an emergency stop is made during image forming operation, an electrifying control driving part 503 is controlled to stop the electrifying operation of an electrifying charger. Almost simultaneously with this a developing revolver driving part 506 is controlled to rotate a revolver developing unit, so that a developing unit at a developable position is retreated to separate the developer from the surface of a photoreceptor drum. Then, a photoreceptor driving part 507 is controlled to turn off a photoreceptor motor for rotary drive. The developing bias voltage corresponding to the potential by electrification of the photoreceptor drum is applied to a developing roller, until the developer becomes the noncontact state. Thus, the useless developer is never stuck to the photoreceptor drum.  Further, after switching into the noncontact state, the useless developer is never stuck.

Title: Driving gear
Inventor: KUWABARA YASUO
IPC: B65G27/16
Filed: 1986-03-31
Abstract: PURPOSE:To improve moving and stopping position accuracy and a response speed, by constituting a driving gear such that a signal inputting member, being arranged in the opening end of a driving member fixing its one end and opening the other end, vibrates the driving member, in case of the driving gear for a material conveyer. CONSTITUTION:If a signal waveform of predetermined frequency is input to an input electrode 2 provided in an opening end 1b, a standing wave is generated on the surface of a driving plate 1. This standing wave generates no advance, but a traveling-wave is generated by changing a phase if the phase of an input waveform is changed. Accordingly, a material moves by successively generating the traveling-wave. While the traveling-wave can be optionally generated by the timing of change of the phase. Accordingly, the material, starting to move and stopping, can be controlled with high accuracy in good timing.

Title: Heat sensitive picture recorder capable of representing gradation
Inventor: NAITO KAORU
IPC: B41J2/36
Filed: 1985-04-09
Abstract: PURPOSE:To shorten a printing time for one line and delete a generation of a deep rib by dividing plural thermal member dots into an odd number and an even number of first block and second block and dividing strobe pulses into a first and a second pulses in which a phase is reverse to each other and supplying to the respective blocks. CONSTITUTION:After previously heated, subsequently the printing corresponding to a level data signal LD11 is performed by strobe signals SS1, SS2. At this time, in SS1 and SS2, signals having phases reverse to each other are applied, so that bits D1, D3, D5, D7, D9 belonging to a block B1 and bits D2, D4, D6, D8, D10 belonging to a block B2 are alternately driven. Accordingly, paying attention to a specific dot, for instance, D3, a total sum of an energizing time in this period becomes 1/2 of t1 and is insufficient for the time t1 required for obtaining the density corresponding to the level data signal LD11. Since during SS1 being '0', and D3 being not energized, SS2 goes to '1', D2 and D4 adjacent thereto are energized, and by adjacent effect, a section of D3 is also heated, the same printing density as energizing continuously for a time of t1 can be obtained.
