PROBLEM TO BE SOLVED: To enhance the crime preventing performance of an opening/closing device provided with an emergency opening/closing body integrally at the main opening/closing body such as a vestibule door. SOLUTION: A building entrance 12 formed in the external wall 11 of a building 10 is provided with the vestibule door 18. An emergency doorway 28 formed at a door body 24 of the vestibule door 18 is provided with an emergency door 31, and the emergency door 31 is provided with an emergency locking device 35. The door body 24 of the vestibule door 18 is provided with a door load sensor 44 detecting the load applied to the door body 24. A home server 41 determines whether the load is applied to the door body 24 based on a detection signal of the door load sensor 44, and determines whether the load is larger than a reference value if the load is applied. When the load is larger than the reference value, the home server 41 determines that the vestibule door 18 is in a non-openable state and performs locking control of the emergency locking device 35.

Abstract:
PROBLEM TO BE SOLVED: To properly restrain deterioration of EGR controllability in switching a mode for actuating a turbo supercharger. SOLUTION: This control device of an internal combustion engine with a supercharger has first and second superchargers, an exhaust air switch valve actuated to switch a mode for actuating the superchargers, and an EGR device. Concretely, the mode for actuating the supercharger can be switched by controlling the exhaust air switch valve to be opened or closed, according to an operation area of the internal combustion engine. During the recirculation of the exhaust gas, when there is any operation area in which the mode for actuating the supercharger should be switched, an opening degree of the exhaust air switch valve is set according to an exhaust gas pressure and an exhaust gas flow rate.

Abstract:
PROBLEM TO BE SOLVED: To quickly raise the rotational speed of a diesel engine during shift down of an automatic transmission and to prevent lowering of a catalyst bed temperature of an exhaust emission control catalyst. SOLUTION: During shift down of the automatic transmission (yes at S102), an engine rotational speed NE becomes a target engine rotational speed (raised target engine rotational speed NEupt) according to the shift down state, and also, the intake air amount is increased at steps S110 to S114 to prevent smoke. Moreover, at steps S116 and S118, a reducing agent (fuel is used here) is added to exhaust gas, so that lowering of the catalyst bed temperature of the exhaust emission control catalyst can be prevented during increase in the intake air amount at steps S110 to S114.
