Title: Observed-information processor of weather radar
Inventor: HASHIMOTO HIDEKI
IPC: G01S13/66
Filed: 1993-07-30
Abstract: PURPOSE:To provide a observed-information processor of a weather radar, which can automatically identify a precipitation region and can objectively recognize the identify of the precipitations obtained in each observation, which are updated from time to time. CONSTITUTION:Precipitation regions are sequentially identified for every observation with a precipitation-region identifying part 1. The representative position is computed for each precipitation region with a representative-position computing part 2. The representative position at the next observation is predicted based on the representative positions in the past precipitation regions with a representative-position predicting part 3. The correlation between both position is observed with a correlation processing part 4. Thus, whether the identified precipitation region is the same region as the previous precipitation or not is automatically judged.

Title: Core material for microcapsule toner
Inventor: DATE HITOAKI
IPC: G03G9/087
Filed: 1988-08-02
Abstract: PURPOSE:To enhance the flocculating property of the toner itself and the penetratability of the toner to recording paper by consisting the core material of branch polyethylene (PE) wax having penetration of a specific value or above and a coloring agent. CONSTITUTION:The core material for the microcapsule toner is formed by using the branch PE wax as the binder. The branch PE refers to a so-called a high-pressure method PE (LDPE) and is required to have >=15, more preferably >=25 penetration by the method specified in JIS-K-2530. Further, the core material contains the coloring agent (dye, carbon black, etc.) in addition to the binder as the essential components. The branch PE wax is preferably incorporated at >=90wt.%, more preferably >=94wt.% into the material. The plastic deformation characteristic and the penetration power to the paper are improved in this way and since the PE chain has the branch structure, the flocculating power of the binder itself is enhanced by the entanglement of the molecules of the binder with each other. The fixability is thus improved.
