Title: Locking structure by flaps of package container made of corrugated board
Inventor: TERAYAMA KENJI
IPC: B65D5/10
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a satisfactorily sealable, and inexpensive package container made of corrugated board whose flaps are easy to close. SOLUTION: An outer flap 26 is provided with two creases 27 and 28, and a U-shaped cut made slightly beyond the creases 27 and 28 forms a tongue 30 above it when the fold flap 32 is folded inside along the creases 27 and 28 and forms an insertion opening 31 beneath the tongue 30. At the front end of an outer flap 33 a tongue 34 which is inserted into the insertion hole 31 is formed. The tongue 34 is longer in vertical width than the opening of the insertion hole 31 to a certain degree. The vertical widths of the outer flaps 26 and 33 are predetermined so that the outer flaps 26 and 33 properly repel each other by means of the elastic force of their corrugated board member when the tongue 34 is inserted into the insertion hole 31 with the outer flap 26 folded inside along the creases 27 and 28 and then they are pushed down with their front ends face each other.

Title: Stability control device for internal combustion engine
Inventor: ITOYAMA HIROYUKI
IPC: F02D45/00
Filed: 1993-12-29
Abstract: PURPOSE:To prevent erroneous detection of stability owing to an individual difference between a number of revolutions detecting means and an engine itself and to improve control precision of stability control by a method wherein when stability of an internal combustion engine is controlled by detecting a rotation fluctuation, a target value of stability is learnt and variably set. CONSTITUTION:It is decided at S71 by a control unit with a built-in microcomputer whether an operation condition is a learning condition. When it is the learning condition, a present learning condition is read, and a weighted average value Sfiid of a rotation fluctuation amount is calculated. When the weighted average value Sfiid is below a given value, division by a gear position correction factor SLG is effected to determine a learning value GSL of a rotation fluctuation at S72-S76. The determined learning value GSL is stored at the corresponding operation region of a learning map togetherwith a set value of a learnt flag FSL at S77 and S78. A stability target value is set by multiplying a learning value stored at the learning map with a gear correction factor.
