Title: Gearshift controlling method for vehicle with continuously variable transmission
Inventor: HAYASHI TSUTOMU
IPC: F16H61/40
Filed: 1987-03-24
Abstract: PURPOSE:To enable quick starting, by constituting a transmission gear ratio to be held to the maximum value (LOW) at a time when engine speed exceeds the specified value and car speed is less than a certain setting value. CONSTITUTION:Set value V1 is set and prestored in a control device C as a control condition at time of gearshift control. This set value V1 is set at car speed to be regarded as a vehicle starting. And, set value Ne1 of engine speed is stored and it is less than this set value Ne1, it means such speed that is regarded as an engine stopping. And, when the engine speed goes beyond the set value Ne1 and car speed is less than the set value V1, a transmission gear ratio is held to the maximum value (LOW), not responsing to the engine speed. For this reason, at time of starting even if the engine speed is increased in a state of racing or half-clutch state, the engine can be started at the maximum transmission gear ratio, namely, LOW, so that it secures high driving force, thus quick starting is possible.

Abstract: PURPOSE:To efficiently smelt and reduce powdery ore by charging the powdery ore along with oxygen into the fluidized bed of a carbonaceous solid reducing agent in a shaft reducing furnace, and blowing an oxygen-contg. gas into the packed bed at the appropriate depth of a jet. CONSTITUTION:The bed 2 packed with a carbonaceous solid reducing agent is formed in the shaft reducing furnace 1, and an oxygen-contg. gas 6 is blown in from a tuyere 5. Consequently, a race-way of a jet depth J is formed in the packed bed 2, and the reducing agent is burned.

Powdery ore 4 is charged into the fluidized bed 3 along with a flux and oxygen, hence the ore is smelted and reduced, and molten metal 10 and molten slag 9 are formed. In this case, the jet depth J of the blown-in gas 6 is limited to conform to the equation 0.1<J/D<0.3 (where J is the jet depth in meter and D is the inner furnace diameter in meter at the tuyere-fixing part). The fluidized bed 3 is formed uniformly and stably in this way, and powdery ore 4 is efficiently smelted and reduced.
