Title: Method for controlling flow rate of gas to be blown to refining furnace
Inventor: YAMANE AKIRA
IPC: C21C5/34
Filed: 1985-06-10
Abstract: PURPOSE:To speed up the rise and fall of the flow rate of gas to improve a transient response characteristic in the stage of changing considerably the flow rate of the gas to be blown by changing over the set value after the change of said flow rate to the set value of an excessive flow rate and controlling the flow rate to a constant rate when the changed set value is attained. CONSTITUTION:The gas A past a flow rate control valve 16 is blown through a tuyere 12 into a converter 10 at the flow rate controlled to the set flow rate value. A change- over circuit 24A changes over the flow rate to the max. set value and outputs the same to a flow rate controller 22A to control the flow rate to the max. value in the stage of increasing considerably the flow rate of the gas A. Then the back pressure of the tuyere increases and therefore the pressure increase is detected by a pressure gage 20. The circuit 24A changes over the max. set value to the set value after the change by the command of a pressure controller 21. The controller 22A controls the flow rate to the constant rate by the changed set value. The set value is changed over to the min. set value by the similar operation and the control to the constant flow rate is executed after the set value is returned to the changed set value in the case of decreasing considerably the gas A.

Abstract: PURPOSE:To eliminate scattering of a toner, fog, and an uneven development density by applying a voltage whose polarity is opposite to that of a transfer means, between a developer carrying body and a cylindrical elastic body, in a period in which a development is not executed. CONSTITUTION:When an electrostatic latent image which has been minus-electrified on a photosensitive drum 22 has been opposed to a developer 28 which has been plus- electrified on a developing roller 34, the developer 28 is scattered by an electrostatic force of the electrostatic latent image on the photosensitive drum 22 and can develop its latent image. After the development has been executed, the developer 28 which has adhered onto the surface of the developing roller 34 is scraped down by a fur brush 35, and also, in a period in which the development is not executed, the polarity of the second DC high voltage power source 42 is switched, and between the developing roller 34 and the fur brush 35, a voltage whose polarity is opposite to that of the time of development is applied. As for an applied voltage in this case, about 30V-250V is desirable, a surplus developer on the developing roller 34 is attracted to the fur brush 35 side by an electric field, and a development hysteresis on the developing roller 34 is erased. In this way, an image of a high quality having no ghost can be obtained.

Abstract: PURPOSE:To copy making the contour and fold of a book blank without reference to its size by photodetecting reflected light from an original indication table and detecting the fold of the book, and preventing toner from sticking on the detected fold part. CONSTITUTION:For example, a switch 29 provided near an original platen is turned on and a signal generated by detected an original pressure plate 21 not contacting original platen glass 19 is inputted to an input port i12 of an MP55, which then judges that an original 20 is a book. When there are halftones having a reflection factor lower than a predetermined reflection factor in reflection density detected by a reflection density detector 35, the MP55 judges that a set of the halftones is present in the edge direction of the original 20 and outputs control signals to respective output ports O1-O9 so that LEDs corresponding to the positions of the halftones turn on. A driver 62 which receives the output turns on the LEDs corresponding to the positions of the halftones. Consequently, toner is prevented from sticking on the halftone positions.

Abstract: PROBLEM TO BE SOLVED: To elongate the life and improve the efficiency by alternately repeating operations of continuously impressing pulse voltage at the same polarity for a plurality of times and then continuously impressing it to the other same polarity at plurality of times, at least, between a pair of electrodes. SOLUTION: A pulse voltage from a pulse generating means 1 is distributed to two or more pulses impressed continuously to the same polarity by changeover of a switch at a prescribed period and fed to lighting circuits A, B 3, 4 composed of FET 5, 6, 6, resonant capacitors 7, 8, and a transformer 9 respectively. The pulsed voltage of the inverse polarity is generated by the generation of a back electromotive force and a prescribed waveform positive and negative voltage pulses are alternately and repeatedly impressed between electrodes 11, 12 covered with, for example, a dielectric layer of a planar fluorescent lamp.  This distribution can periodically change over between the positive and negative polarities of the electrodes 11, 12 without loading too much to one of them, and the period of distributing it to the positive and the negative is set to every plurality of pulses so as to reduce the power loss in a transformer or the like based on the change of the polarity.

Title: Bank switching system
Inventor: KOBAYASHI ATSUSHI
IPC: G06F12/06
Filed: 1990-05-18
Abstract: PURPOSE:To omit the program operations at switch of banks and to prevent the occurrence of program mistakes by producing a program with its address set opposite to a memory bank which is referred to in each module of the program. CONSTITUTION:A program production part 1 divides a control program into plural modules and secures the correspondence between the memory bank which is referred to in each module and the address of each module to produce a program. An address analysis part 2 analyzes a program address at execution of a program and designates a memory bank corresponding to the analyzed address. A bank switch part 3 switches the memory bank to the corresponding one based on the result of analysis of the part 2. Thus the program address is decoded by the hardware and the memory banks can be switched based on the decoding result. As a result, the bank switching operations carried out by a program are omitted and the occurrence of bags caused by the software is eliminated.
