摘要： In a method for preparing a high .alpha.-type silicon nitride powder by adding to and mixing with metallic silicon powder a copper catalyst and nitriding the mixture in a non-oxidizing gas atmosphere containing nitrogen or ammonia at 1,000.degree. to 1,500.degree. C., the amount of copper catalyst is limited to from 0.05 % to less than 0.5 % by weight of copper based on the weight of the metallic silicon. There is obtained silicon nitride powder of high purity at low cost and high efficiency since the copper catalyst can be efficiently removed from the silicon nitride powder through conventional acid treatment.

摘要： A drive unit mounting structure for a three-wheeled vehicle which has a rear fork pivotably connected to a vehicle body and supporting thereon a drive unit. In order to suppress hopping movements of the vehicle, front and rear portions of the drive unit are pivotably mounted by front and rear link members on the rear fork. The front link member has a longitudinal axis extending obliquely, when viewed in side elevation, toward a point where a pair of rear wheels drivably coupled to the drive unit contacts the ground. The front and rear link members include rubber mounts for dampening vibrations of the drive unit in operation.

摘要： An improved form of three-wheeled vehicle of the type having a front wheel arranged in the longitudinal plane of symmetry of the vehicle and a pair of rear wheels arranged symmetrically with respect to the vehicle plane. The pivot joint interconnecting the front and rear frames of the vehicle has a turning axis offset from the vehicle plane to that side of the vehicle on which the driving rear wheel is arranged and extending in a direction inclined laterally outwardly from rear to front of the vehicle. Such pivot arrangement is highly effective to improve the driving stability of three-wheeled vehicles of the type concerned, without involving any structural complication or increase in cost of production.
