Title: Method for operating coke oven
Inventor: FUKUDA KOICHI
IPC: C10B57/00
Filed: 1995-04-13
Abstract: PURPOSE: To prevent pushing-out difficulties in a coke oven to stabilize the operation by determining in a specific manner the carbonization time which results in the horizontal burning loss corresponding to a controlled value of the pressure necessary for coke cake pushing-out, and using the carbonization time as the minimum carbonization time. CONSTITUTION: The horizontal burning loss corresponding to a controlled value of the pressure necessary for coke cake pushing-out is estimated from the relationship between the horizontal burning loss Xc represented by the formula and the pressure necessary for coke cake pushing-out. The relationship between carbonization time and the loss Xc is determined beforehand using a test oven. The carbonization time which results in the estimated value of loss Xc is determined and used as the minimum carbonization time to operate a chamber oven.  In the formula, μS, is the coefficient of static friction between the coke cake and the oven bottom; μW is that between the coke cake and the oven wall; L is the oven length; b is the oven width; ρ is the apparent specific gravity of the coke cake; g is gravitational acceleration; dx is the length of a minute section in the oven length direction; x is the distance from the discharge opening; T is taper; α is the compressibility during pushing-out; P is the pushing pressure imposed on the minimum section; and dP is pushing pressure loss in the minimum section.

IPC: G08G1/0969
Filed: 1991-04-19
Abstract: PURPOSE:To shorten a route search time by limiting the range of route search range and reducing the number of crossings as objects for consideration in searching a route. CONSTITUTION:A crossing net list is so prepared as to correspond to crossings, and have at least the page number and unit code of a map including the concerned crossings, all crossings adjacent thereto and distances among the crossings. The list so prepared is saved, for example, in a map data memory section (CD-ROM) 11. In searching a route, a route search section 15f obtains units of a map containing a set departure point and destination from an operation section 14, and determines a rectangular area using the units as diagonal units, or a rectangular area slightly larger than said rectangular area, as a search range. Furthermore, the section 15f refers to the crossing net list and examines whether a crossing is existing in the units of the concerned rectangular area. If not, the route search is performed, while excluding the concerned crossing from the object of the route search.

Abstract: PURPOSE:To improve the versatility of a recorder by setting a reference toner concentration according to the detected concentration of toner developing the pattern of an electrostatic latent image, detecting a toner concentration by means of a developing device and controlling toner replenishment so that the concentration reaches the reference toner concentration. CONSTITUTION:The density of a visible pattern is detected by a pattern density sensor 18P, and the reference toner concentration is set according to the detected density. When the toner concentration of developer becomes lower than the reference concentration, toner is automatically supplyed by the toner supply control means 210, so that the toner concentration of the developer of the developing device 11 practically becomes equal to the reference concentration, and reaches the toner concentration specified by a specifying means 30: The toner concentration can be adjusted or set by the specifying means 30. Consequently, even when the hardware of the recorder and processing conditions are the same, an image is developed in a concentration adjusting range in which the toner concentration is deviated from high concentration side to low concentration side, and vice versa. Therefore, a record either in high or low density is attained and the versatility of the recorder is improved.

Abstract: PURPOSE:To constitute a simple and inexpensive device, by a method wherein, in a self-correlation tachometer, a rotary signal is converted into a pulse, holding a period information, by the use of a probability statistical method, and a self correlation function thereof is calculated. CONSTITUTION:A pick up 1 outputs a rotary signal which changes periodically corresponding to a spin of a rotary object togetherwise a time. A signal, having uniformity in a probability concentration function of an amplitude, is generated from a quasirandam signal generator 4, and is compared with the rotary signal by means of a comparator 3 to produce a ''1'' when the rotary signal is large. The pulse produces a signal which has a rotary period information like a high probability in which the signal goes to a ''1'' when the amplitude of the rotary signal is large, and it goes to a ''0'' when the amplitude is small. The signal is produced into a specimen by means of a circuits 5 and 6, the product of the signal, which is left intact, and a signal, which is delayed by a shift register 7, is found by means of an AND 8, and is integrated and is formed into an analogue by means of a filter 9. From the delay time of the register 7 at a time when a circuit 10 detects a maximum value, the rotary period is calculated and the number of revolutions is indicated.

Abstract: PURPOSE: To provide a wet type developing device of improved image quality by a conductive guiding plate being electrically insulated, a grounded counter electrode plate forming a recording paper passage, a means of supplying the developing solution between said conductive guiding plate and the counter electrode plate, etc.  
     CONSTITUTION: A conductive guiding plate 1 is electrically insulated from others and is held floated. A counter electrode plate 2 is opposedly disposed by leaving a predetermined space from this conductive guide plate 1 and this is held grounded. Recording paper 3 is of the constitution consisting in laminating a photoconductive layer 5 on a base 4 and is electrophotographically formed with electrostatic latent images of negative electric charge. The developing solution dispersed with the positive-charged toner is being supplied between this recording paper 3 and the counter electrode plate 2. Since the conductive guiding plate 1 is held insulated, it assumes the positive potential similar to that of the base 4 owing to dielectric polarization effect, thereby electrostatically repulsing the toner being charged to the same polarity as that of the same. As a result, the toner is prevented from sticking on the nonimage part of the recording paper.

When a transmission request comes from the master board 5 to a host CPU 7 of the LAN interface at a time point (a), for example, the node No.4 possesses the transmission right at the time point (a) and the node No.1 possesses the transmission right at a time point (b). Therefore, the host CPU 7 of the LAN interface board 4 transmits the transmission request from the master board 5 to a local communication controller 6 and starts data communication. Thus, there is no collision even in the case of data transmission and the high reliability can be kept even in real-time control.
