Title: Base material for greening slope and base structure for greening the same
Inventor: TABATA YOSHINARI
IPC: E02D17/20
Filed: 2000-06-28
Abstract: PROBLEM TO BE SOLVED: To provide a base material for greening a slope, capable of properly conducting greening of the slope. SOLUTION: This base material for greening the slope contains an organic substance containing organic nitrogen, porous clinker ashes excellent in water retentivity, a soil material, and microorganisms, preferably, in amounts of 50-70 pts.wt., 15-35 pts.wt., 10-30 pts.wt., and a small pts.wt., respectively. The base 14 for greening the slope 11 is composed of a lower base 12 and an upper vegetative base 13 comprising the base material for greening the slope. The microorganisms settle in the porous clinker ashes and gradually decompose the organic nitrogen contained in the organic substance into ammonia nitrogen over a long period, so that plants on the slope 11 are supplied with the decomposed organic nitrogen as a nutrient. Thus, the plants are not excessively supplied with the nutrient at an initial stage of their growing, but can be thereafter supplied with the nutrient in such a suitable manner that the nutrient which have been leaked from the soil with weathering is supplemented when the plants require the nutrient at their growth stage, and therefore the greening of the slope by the plants can be properly conducted.

Title: Substrate processor and method therefor
Inventor: MATSUYAMA YUJI
IPC: B05D1/40
Filed: 2000-07-27
Abstract: PROBLEM TO BE SOLVED: To increase uniformity of processing, when a substrate, e.g. a wafer is subjected to development processing, etc. SOLUTION: While a wafer W is held at a wafer holding part 2 and temperature control liquid A is jetted from a flow passage 41 to the peripheral edge region on the reverse surface of the wafer, a developer D is applied to the wafer surface. Then while the temperature control liquid A is jetted from the flow passage 41 to the peripheral edge region on the wafer reverse surface, the wafer W is rotated for a specific time to carry out development. Consequently, the wafer holding part 2 which has large heat capacity in a region near by the center part of the wafer W heats the wafer W to form a liquid film of temperature control liquid A in the peripheral edge region of the wafer W, which is thereby heated.  At this time, since the wafer W is rotated, the developer D is stirred to suppress the generation of the temperature distribution of the developer D in the surface of the wafer W, and then development unevenness due to a temperature difference is suppressed, and a uniform developing process can be performed.
