Title: Melt spinning method
Inventor: MATSUI MASAHIRO
IPC: D01D5/092
Filed: 1982-12-20
Abstract: PURPOSE:The part between the spinning and the cooling chimney is blocked, the position where the blowing speed of cooling air becomes maximum is specified and the average blowing speed to this position is set to the maximum to inhibit the deposition on the spinneret surface and produce the titled fiber of high strength and elongation with less yarn unevenness. CONSTITUTION:When a high-molecular-weight polymer is subjected to melt spinning using a chimney from which cooling air is blown to the yarn, the part between the spinning pack 1 and the cooling chimney 4 is almost blocked except the space within 30mm. below the spinning pack 1 set to the spinning block 9 and other small spaces for the yarns to pass through and the molten polymer is extruded through the spinneret to form a yarn Y. Further, in the yarn-cooling chimney 5, the position at which the air-blowing speed becomes the maximum is set within 30mm. below the top end of the chimney and the average speed is kept larger in the 300mm. position than any other 300mm. long parts to effect cooling and obtain the objective yarn.

Title: Picture data compression restoring system
Inventor: SATO SHINICHI
IPC: H04N1/417
Filed: 1984-10-24
Abstract: PURPOSE:To compress a memory required for data storage nearly to 1/2 of original data by concentrating the distribution of errors between forecast values and true values and the density of each picture element onto nearly zero to bring the word length of the original data into a length of 1/2. CONSTITUTION:The compressed data is inputted on by one byte. When the content of the inputted 1 byte is not (11111111), i.e., -128, the data is restored as a forecast error eij. If the content (11111111) appears, the succeeding two bytes are read as one data and restored as the eij. When the eij is obtained, the adjacent picture elements restored already are used to calculate a forecast value xij to a true value xij thereby restoring the true value of the picture element (i, j). The operation is applied to all picture elements to restore the original picture data from the compressed data.

Title: Developing device
Inventor: ITOU KATSUYUKI
IPC: G03G15/06
Filed: 1983-11-29
Abstract: PURPOSE:To enable retention of stable potential of an insulating face even when development is continued by using a developing sleeve coated with an insulating material, to reduce danger of discharge, and to ensure development superior in safety and image quality by forming an electrode set to a constant potential. CONSTITUTION:A magnetic toner 5 is fed from a toner hopper 4, passed through a developing zone between a photosensitive drum 1 and a developing sleeve 2, then, separated from th sleeve 2 with a toner scraper 7, and recovered into a hopper 4. An electrode 6 set to a constant petential is located at the position downstream from the scraper 7 in contact with the sleeve 2, and the toner 5 does not intervene between this and the sleeve 2. Since electrostatic charge of an insulating layer 2b leaks to the electrode 6, when the layer 2b cntacts with the electrode 6 and passes over it, the potential of the layer 2b becomes similar to that of the electrode 6. When the layer of a charged toner has a voltage of +100V, the potential of the sleeve 2 becomes about zero potential with respect to the drum 1. Since the electrode 6 also has an effect of compensating the charge of the toner 5, development superior in safety and imge quality can be executed.

Further, after completion of the drilling, the rotary arms 20 are again normally rotated, and therefore, abuts against the eccentric section (w). The rotating arms of the rotary arms 20 is detected by a detector 18, and is transmitted to the control device 19 in which it is compared with the previous stored rotating angle data. If it is out of a tolerance, a failure in working due to a chuck slip is indicated. Thus, it is possible to enhance the working efficiency.
