Title: Method for operating coke oven
Inventor: TOSHIMITSU RYOICHI
IPC: C10C1/19
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain coke with desired qualities and tar with a low degree of heaviness without causing the decrease in operating rate of a coke oven by additionally charging coal in the course of from the beginning of carbonization after charging coal into a carbonization chamber to the completion of primary shrinkage of the coal layer. SOLUTION: After a coal charge charged to the height of the leveller hole of a carbonization chamber starts carbonization and exhibits the primary shrinkage and when the height of the coal charge decreases to a ceratin extent and the upper space of the chamber is widened, additional coal is charged. The additional coal charge can keep the lowering of the coal layer small and can reduce the increase in the upper space of the carbonization chamber. When the coal layer sinks again after the additional charging of coal, further additional coal is charged so that the coal layer height changes in zigzag with time, thus enabling the increase in the upper space of the carbonization chamber to be kept small. The discharged tar is inhibited from becoming heavy, and tar with a low degree of heaviness is obtd.

Title: Air conditioner
Inventor: MORI YUJI
IPC: F24F5/00
Filed: 1987-05-12
Abstract: PURPOSE:To prevent a trouble caused by a rise in the temp. of a fan-motor and a rise in ventilating noise by forming a through hole located between an outdoor side heat exchanger and a fan in a partition plate located between a ventilating circuit block and a refrigeration cycle block. CONSTITUTION:When a cross-flow fan 1 is rotated, wind flows as the arrows indicate. At that time, by opening a through hole 4 in a partition plate for the fan 1 except a ventilation flue block 10, wind flows also from a refrigeration cycle block 9. The heat of a fan-motor 7 is allowed to escape in the form of not natural convection but forced radiation and in trying to cool the fan-motor a trouble caused by a rise in temp. can be prevented. Further, because the through hole is opened toward the downstream side of a heat exchanger 2, even if ventilating resistance is increased by the frosting on the outdoor side heat exchanger 2 at the time of space heating operation, the fan 1 sucks air through the hole 4 to cause no surging phenomenon and be able to prevent a rise in the ventilation noise of the fan 1.

Abstract: PURPOSE:To prevent the deterioration of a picture quality at the part of the upper corner, the left corner or the right corner of a picture frame by using a level, determined by using a signal level or the signal level of an inside reference picture element as the reference picture element existing inside a transmission picture frame, as the signal level of the reference picture element, protruding outside, when a part of the reference picture elements protrudes outside the transmission picture frame. CONSTITUTION:At first, in a case that an encoded picture element X1 is located at the upper corner of the picture frame like 2, three reference picture elements on one line exist outside the picture frame. In such a case, the value A1 of the reference picture element, located inside the picture frame, is used as the values of these three reference picture elements. Besides, in the case that the encoded picture element X2 is located at the left corner of the picture frame like 3, the two reference picture elements of left side exist outside the picture frame. In such a case, the value C2 of the reference picture element just above the X2 is used. Further, in the case that the encoded picture element X3 is located at the right corner of the picture frame like 4, the value C3 of the picture element just above the X2 is used. As the result, a forcast error can be expected to be small, and accordingly, a quantized noise comes less, and the deterioration of the picture quality at the circumferential part of the picture frame can be prevented.
