Title: Vacuum packaging apparatus
Inventor: FURUKAWA TAKAO
IPC: B65B31/02
Filed: 1988-02-12
Abstract: PURPOSE:To speed up vacuum packaging operation and improve operational efficiency, by providing a plurality of suspended chambers equally spaced around the peripheral edge of a horizontal rotor, accommodating a packaging bag filled with a commodity in the chamber upon reaching the downstream point of its circular path by the rotation of the rotor and evacuating the chamber and sealing the packaging bag during one turn. CONSTITUTION:When six chambers 16 moving along a circular path integrally with a rotor 14 reaches a downstream point of the circular path, two lids 45 and 46 are released therefrom, whereby a packaging bag 56 filled with a commodity is fed into the chamber 16 together with a container 55. At the start of rotation of the chamber 16, the lids 45 and 46 are placed back thereon, the chamber is evacuated and the opening edge of the bag 56 is heat sealed. Upon return to the downstream point of the circular path of the chamber 16, the packaged commodity 59 is drawn out thereof together with a metal container 55 and carried out by a conveyor 54. The commodity packaging in this way results in an increase in the friction between the packaged bag and the chamber, thereby preventing the positional shift therebetween resulting in a high-speed rotation of the chamber.

Title: Air-fuel ratio controller for engine
Inventor: ISEI MASAAKI
IPC: F02D41/04
Filed: 1989-02-14
Abstract: PURPOSE:To prevent any sudden increase of engine instability due to a large variation in the lean best value by setting both upper and lower limit guard values of a controlled variable as centering on the controlled variable when an air-fuel ratio is controlled to the lean best. CONSTITUTION:When an air-fuel ratio is in (a), it is moved to the lean side as much as a specified minute value, and whether instability is less than the desired value again or not is judged. Repeating this operation, the value moved to the rich side as much as the specified value than the air-fuel ratio when the instability first becomes more than the desired value is set as the lean best value. Next, a lower limit guard value is set at the more specified value lean side than the air-fuel ratio of this lean best, while an upper limit guard value is set to the specified value rich side. At time of normal driving, control over the air-fuel ratio is performed within the range of both upper and lower limit guard values, and thereby driving is carried out in a stable state at all times. In this connection, control over the setting of the lean best value or the like is performed when an engine is in an idling state as well as when conditions including a warming-up state or the like are completed.
