Title: Method for continuously cutting four corners of bag into arcuate form
Inventor: IWASE TAKASHI
IPC: B65B21/00
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent an abnormal shape from occurring on a cut surface by providing a gap between rectangular bag materials which are intermittently moving and positioned forward and backward and by simultaneously cutting two corners of the adjacent forward and backward bag materials across the gap into an arcuate form. SOLUTION: As soon as composite strip sheets A, B are cut by cutting blades 5, 6, they are held between belts 11, 12 and moved forward by a slightly longer distance than a feed distance of a feed roll 4. As a subsequent bag is fed by the feed roll 4, as soon as it is cut it is held between the belts 11, 12 in a similar manner, and it is correctly fed by the same distance as the previous one. Slightly more and rapid feeding by the belts 11, 12 causes a small gap (small distance) between a bag positioned forward and a bag positioned backward. Three pairs of male punches 14 and female punches 15 at a cutting position cut adjacent corners of the bags which have been intermittently carried at the small distance.

Title: Vacuum degree control method
Inventor: YAGUCHI SEIICHI
IPC: G11B15/43
Filed: 1985-06-17
Abstract: PURPOSE:To execute the economical detection by detecting the change of the degree of vacuum from the change of the electric current to supply to the motor. CONSTITUTION:The pulse width of the electric current supplied to the motor to drive a supply reel 1 is increased by increasing the degree of vacuum of the vacuum part 5. For such a reason, the pulse width of the electric current supplied to the motor is corresponding to the degree of vacuum, and when the change of the pulse width is detected, the change of the degree of vacuum of the vacuum part is detected. Since the change of the pulse width can be comparatively easily detected by the electric circuit, based upon the changing quantity of the pulse width detected in such a way, the degree of vacuum of a vacuum part 5 is made smaller. Then, the torque given to the supply reel 1 comes to be smaller and the tension of a magnetic tape 6 is constantly kept. Thus, the high-priced vacuum degree sensor comes to be unnecessary for the detection of the degree of vacuum and the economical efficiency is improved.

Title: Air-fuel ratio feedback control method for electronically controlled fuel injection engine
Inventor: ISOBE TOSHIAKI
IPC: F02D41/12
Filed: 1983-07-18
Abstract: PURPOSE:To obtain a proper air-fuel ratio promptly, for instance, at the time of decelerating operation of an engine, by interrupting feedback correction of the air-fuel ratio in case that the required injection quantity of fuel is smaller than a reference injection quantity in the neighbourhood of the minimum injection quantity determined by the minimum valve opening period of an injector. CONSTITUTION:According to the control method of this invention, the fuel injection period is calculated in an ECU40 on the basis of the oututs of a crank-angle sensor 36 and a sensor 22 for detecting the pressure in an intake pipe, and a new, required injection period is calculated by multiplying the fuel injection period by the already calculated, previous feedback correction factor that is determined by the deviation between a reference air-fuel ratio and the actual air-fuel ratio. Here, judgement is made whether or not the required injection period thus calculated is smaller than the minimum injection period dependent on the minimum valve opening period of an injector 26 that is predetermined by way of simplex evaluation or the like. In case of YES, feedback correction of the air-fuel ratio is interrupted for preventing the air-fuel ratio from becoming over-lean temporarily.
