Abstract: PURPOSE:To improve the yield of products by comparing the measured values of the tensions between respective two adjacent sets of rolls of rolling rolls with reference values thereby successively correcting the revolutions of the downstream rolls in such a manner that the deviation values of these tensions become zero. CONSTITUTION:Respective sets of rolling rolls 14A, 14'A-14H, 14'H are driven by driving control circuits 18A-18H to pass a material 1. Then, setters 24AB-24GH electrically set the tension of the material between respective two adjacent sets of the rolling rolls.

And a deviation signal thereof is generated and the driving control unit circuit 18B  corrects the number of revolutions of a motor 16B until the deviation value becomes  zero, based on this signal. Next, a switch 28BC closes and the revolutions of the  rolls 14C, 14'C are so corrected that the tensions of the material between the rolling  rolls 14B, 14'B and 14C, 14'C become predetermined values; thereafter, the revolutions of the rolling rolls 14D, 14'D-14H, 14'H are corrected in a similar manner.

Title: Facsimile equipment
Inventor: TERAJIMA HISAO
IPC: H04M11/00
Filed: 1984-04-26
Abstract: PURPOSE:To allow the large possibility of connection to an opposite party in automatic retransmission by adopting the structure that the operator sets freely a wait time within a predetermined range of time. CONSTITUTION:Since the polarity of a sender line is inverted when the line is connected to an opposite party, a controller 2 detects it and when the polarity of the sender line is inverted, picture transmission is started. When it is discriminated that no polarity is inverted, whether or not the line polarity is inverted even after 50sec is elapsed is discriminated. When no polarity inversion exists, a telephone line is released and the elapse of the preset waiting time is awaited and when the time reaches the wait time, automatic retransmission is attained. Since the equipment is so designed that the wait time is set freely within the time range decided by the operator in this way, the possibility of the connection to the opposite party is very high in the automatic retransmission.

Abstract: PURPOSE:To obtain the titled material having an improved antistatic property by incorporating a prescribed amount of hygroscopic inorg. salts and a prescribed amount of silicon dioxide fine particle having a prescribed particle size to a back coating layer made of gelatin. CONSTITUTION:The back coating layer of the titled material contains 10-300mg/(m<2>) of the hygroscopic inorg. salts and the silicon dioxide having a mean particle size of 0.1-15mum. The compounding ratio of the silicon dioxide particle to the gelatin in the back coating layer is >=20wt%. The silicon dioxide fine particle comprises a non crystalline silicon dioxide hydrate, a fine particle of glass, and a crystalline silica such as quartz powder. The hygroscopic inorg. salts are exemplified by, for example, potassium bromide and sodium bromide, etc. The compounding amount of the prescribed salt in the layer is necessary to be a range of 10-300mg/(m<2>). When the compounding ratio is larger than the prescribed range, a problem is liable to occur in the sticking property of the material. While when the compounding ratio is less than the prescribed range, the antistatic property of the titled material is insufficient. Thus, the titled material which has excellent anti-sticking and antielectrostatic properties is obtd. The occurings of defect of passing a paper through the apparatus and of sticking a stain to a roller can be prevented in an automatic processing apparatus.
