Title: Exhaust emission control device for internal combustion engine
Inventor: TAKAHASHI TOSHIKATSU
IPC: F02D41/04
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To recover the NOx absorption capacity of a NOx absorbent, by setting an air-fuel ratio to that at a lean side in a case when an amount of NOx absorbed by the absorbent becomes a saturated state during the lean burn control of the air-fuel ratio of an air-fuel mixture, and releasing NOx absorbed by the NOx absorbent. SOLUTION: An exhaust emission control means 16 mounted in an exhaust tube 12, includes a NOx absorbent, and a catalyst having oxidation reduction activity. The NOx absorbent absorbs NOx in a condition that an air-fuel ratio of an air-fuel mixture is set to a lean side, and the oxygen content in the exhaust gas is comparatively high (exhaust gas rich stage), and releases NOx absorbed in the exhaust gas rich stage. On this occasion, the air-fuel ratio is set to the further at the lean side with respect to the lean air-fuel ratio, when the saturated stage of the amount of NOx absorbed by the NOx absorbent is judged during the lean burn control. Whereby the NOx absorbed by the NOx absorbent is released, and the NOx absorption capacity can be recovered.

Filed: 1988-07-07
Abstract: PURPOSE:To drastically reduce the frictional coefficient by forming plural pairs of pressure adjusting holes permitting the mutual communication between the positions which are nearly symmetrical with respect to the center of the air injection surface of an air pad body. CONSTITUTION:Plural groups of each pair of pressure adjusting holes 20d and 20d are formed at the nearly symmetrical positions with respect to the center on the air injection surface 20b of an air pad body 20, separately from another air injection hole 20c group which are formed, keeping a prescribed interval in the nearly radial direction on the air injection surface 20b. Each communication pipe 50e is arranged between the pressure adjusting holes 10d and 10d in pairs. When the air supplied from the air injection hole 20c is jetted onto a surface plate 12, the pressure at the symmetrical position with respect to the center shaft O of the air pad body 20 is adjusted to a certain value by the pressure adjusting holes 20d and 20d, and the pressure center shaft Po and the center shaft O of the air pad body 20 are allowed to correspond. Therefore, a low frictional coefficient can be secured independently of the unevenness of the surface plate 12.

Title: Safety device for inspection of elevator
Inventor: FUJITA HIFUMI
IPC: B66B11/02
Filed: 1990-06-29
Abstract: PURPOSE:To secure the safety of a maintenance and inspection work by detecting whether a worker is on the upper side of the ceiling of a cage or not, and converting the cage operation speed mode from the rating speed mode to the inspection speed mode which is a low speed, depending on the detection. CONSTITUTION:When a worker rides on the upper side of the ceiling 30 of a cage room 26 in a maintenance and inspection work, the ceiling 30 is bent downward by the weight of the worker, and following that, a change-over switch 34 is displaced downward together with one side arm 32 integrally, an actuator 35 is abutted to the tip of the other side arm 33, and thereby the operation speed mode of a cage 2 is converted from the rating speed mode to the inspection speed mode. As a result, when the worker on the upper side of the ceiling 30 operats the cage 2, the cage 2 runs at the inspection speed slower than the rating speed, and a fear that the worker is struck to the ceiling 36 of an elevator shaft 1 can be prevented. Consequently, the maintenance and inspection work can be carried out safely.
