Title: Granular water-retentive agent for soil conditioning
Inventor: HAYAKAWA KAZUHISA
IPC: C09K17/50
Filed: 2001-06-05
Abstract: PROBLEM TO BE SOLVED: To provide a granular water-retentive agent for soil conditioning, which comprises a base material and a water-soluble cellulose ether, an has a particle size such that 10-80 wt.% of the granules pass through a 3.5-mesh sieve (sieve opening: 5.6 mm) as described in JIS Z8801. SOLUTION: When the granular water-retentive agent for soil conditioning is spreaded on a place where an improved water retention is desired, the granules are not dispersed by wind because they contains a less amount of fine powder. Once these granules absorb water by rain or irrigation water, they are caked with each other to become solid and form a water-retentive layer so that they are hard to be dispersed. Therefore, the granular water- retentive agent does not produce a water-content irregularity, even if it is applied onto a sandy soil. Where it is applied onto a sandy soil having some water-retentive force or a place where the soil gets a water-retentive force and become viscous, the agent does not cause reduction of gas phace, which is disadvantageous for plant growth.

Abstract: PROBLEM TO BE SOLVED: To control an occupant constraint device having a plurality of actuatable stages. SOLUTION: This device comprises sensors 14, 16 for detecting a collision acceleration and providing a collision acceleration signal representing the collision acceleration. A controller 22 determines a velocity value 74 and a displacement value 80 from the collision acceleration signal.
