Title: Lead forming device
Inventor: WATANABE KENJI
IPC: B21D5/01
Filed: 1987-12-18
Abstract: PURPOSE:To prevent a group of leads from being constrained and to release the external force by putting one of 1st and 2nd group of leads between a supporting base and a pressure member and performing a bending step by a forming tool at its external end part separately to every group of leads. CONSTITUTION:A ramp 4 is lifted and the pressure member 3 is separated from the supporting base 2. Then, a root part to a package 1a of the 1st group 1d of leads and the 2nd group 1e of leads which are projected respectively, is positioned on supporting pieces 2a, 2b of a supporting base 2. Then, when the ramp 4 is lowered, a pressure piece 3a of the pressure member 3 comes into contact with the root part of the 1st group 1d of leads and the 1st group 1d of leads is put by the energizing force of a spring 6 between the supporting piece 2a and the pressure piece 3a. When the ramp 4 falls further, the external end part of the 1st group of leads is bent downward by a forming tool 7 falling with the ramp 4. Then, the 2nd group 1e of leads are bent in the same way by reversing the direction of the semiconductor device 1.

Title: Air-fuel ratio feedback control device for internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02D41/14
Filed: 1989-12-11
Abstract: PURPOSE:To improve the conversion efficiency of a three-dimensional catalyst by delaying a timing, at which proportional control is made on an air-fuel ratio feedback correction value, based on a ratio or a difference between a total sum of an increase operation amount of an air-fuel ratio feedback correction value and a total sum of a reduction operation amount. CONSTITUTION:A correction value set means B sets the increase and decrease of an air-fuel ratio feedback correction value based on proportional operation at least during rich/lean inversion so that an air-fuel ratio detected by an air-fuel ratio detecting means A is adjusted to a value approximately equal to a target air-fuel ratio, and a fuel feed control means C corrects and controls a fuel feed amount. In which case, based on a ratio or a difference between a total sum of an increase operation amount of an air-fuel ratio feedback correction value determined by an operation amount total sum detecting means D and a total sum of a reduction operation amount, a proportional control delay means E varies and sets a lag time, by which a timing at which proportional control is made on an air-fuel ratio feedback correction value is delayed, on the increase operation side and on the reduction operation side by a lag time set means F. This constitution maintains the conversion efficiency of a three-dimensional catalyst through production of a storage effect.
