Abstract: A method of controlling the gear changing operation in an automatic transmission having a gear transmission actuatable by a gear changing actuator assembly controlled by an electronic control system. When operating the gear changing actuator assembly for a gear changing operation, an interval of time, which elapses after the gear changing actuator assembly is operated, is measured with a timer. The measured interval of time is compared with a preset interval of time. When a lock is detected as being caused at the time the gear changing operation is not completed within the preset interval of time, the gear changing actuator assembly is operated to a gear position different from a gear position which the gear changing actuator assembly has originally been operated to select.

Abstract: In a burner, a combustion cylinder made of a ceramic material is divided into an atomizing chamber and a combustion chamber by a partitioning plate having openings, a fuel injection port of an atomizing device is opened in the combustion chamber, the atomizing device emerging from a corner portion on the downstream side of the combustion cylinder and penetrating through the combustion chamber, an outer cylinder is so arranged as to form an annular air introducing path along the outer circumference of the combustion cylinder, and air introducing holes are formed in the combustion cylinder being tilted along the line of air stream. The outer cylinder is provided with an air intake pipe in the radial direction thereof. The tilting angle of the air introducing holes formed in the combustion cylinder gradually increases starting from a portion opposed to the air intake port formed in the outer cylinder and then gradually decreases as it goes to the side opposite to the air intake port.
