A first vacuum switch 24 detects the boundary between a light load region and a medium load region. A second vacuum switch 26 detects the medium load region and a high load region. A carbureter 8 is controlled by a control device 23 and an actuator 28, and the air-fuel ratio is changed. The control of the air-fuel ratio corresponding to the large quantity EGR is performed by the control device 23 and the second vacuum switch 26. In this consititution, at the time of the discontinuance or decrease in the large quantity EGR, the purification of the exhaust gas and the fuel consumption can be improved by the lean air-fuel mixture.

Filed: 1988-06-24
Abstract: PURPOSE:To obtain a thin film EL element with high luminance and high efficiency and a low driving voltage possible to be applied, by providing an interleaved layers having a forbidden band width changed to be narrow continuously or step by step from a luminous layer side, between the illumines layer and an insulating layer. CONSTITUTION:Interleaved layers 4, 6 to be provided on the both side of a luminous layer 5 can restrict the dead layer than the case of forming of a ZnSe thin film directly on the insulating material layer because a thin film having the composition of ZnSe and CdS which can obtain relatively good crystaline is formed at the stage of contacting with insulating material layer 3, 7 in early time of forming of a film as the interleaved layers. And the interleaved layer which contacts with the insulating material layer has a forbidden band width narrower than ZnS so that the injection of electrons can be performed with the low voltage. In these interleaved layers 4, 6, the composition of the compound thin film is changed so that the forbidden band width of the interleaved layer is continued to the forbidden band width of the luminous layer 5, the scattering of the injected electrons by former interface formed in lattice discontinuity is reduced. The thin film EL element with high luminance and high efficiency and the low driving voltage possible to be applied can be thus obtained.

Title: Multi-layer resin composite type vibration-damping steel sheet
Inventor: MANO JUNICHI
IPC: B32B15/08
Filed: 1989-06-20
Abstract: PURPOSE:To make welding properties better by inserting conductive fine particles of specified grain diameter through a total resin layer between metal sheets. CONSTITUTION:Conductive fine particles having grain diameter (t2) to the total resin thickness (t1) in the range of 0.8<=t2/t1<=2.0 are inserted all through a total resin layer 3 between metal sheets 1 and 2. In that case, when the grain diameter (t2) of fillers 4 to the total resin thickness (t1) is t2/t1<0.8, metal touching between the metal sheets 1 and 2 and the fillers 4 all through the resin is difficult even if the resin layer 3 is between the metal sheets 1 and 2, and because of said resin, electrical short circuit between the metal sheets 1 and 2 is not formed to lower the welding properties. On the other hand, when the grain diameter of the fillers 4 is t2/t1>2.0, bonding strength between the resin and the metal sheets gets smaller to generate peel-off between the metal sheets 1 and 2 and the resin layer 3 at the time of mold processing.
