Title: Production of silk fibroin powder
Inventor: MURASE AKIFUMI
IPC: A23J1/10
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for obtaining silk fibroin powder of high quality in high yield in a shorter time than that required for the conventional process. SOLUTION: The silk fiber after scouring is dissolved in a water+alcohol solution including natural salt, for example, sodium chloride. This solution is diluted by a factor of about 40-50-fold, sufficiently stirred, then left to stand to precipitate fibroin. The precipitated fibroin is separated, the remaining neutral salt is removed from the fibroin by washing. Finally, the washed fibroin is dried at about 30-50 deg.C, crushed, when it is sufficiently dried to give finely crushed fibroin powder.

Filed: 1994-08-31
Abstract: PURPOSE: To obtain an electric automobile in which purification of exhaust gas is facilitated using a small-sized light weight internal combustion engine by charging an electric double layer capacitor with output power from a generator through a switching regulator and driving a motor with power being fed from the electric double layer capacitor. CONSTITUTION: An internal combustion engine 10 drives a generator 11 to generate power which is fed through a switching regulator 30 to a high capacity electric double layer capacitor 20 thence to a load, i.e., a motor 50 for driving the running wheel. Consequently, a low output internal combustion engine 10 for driving the generator can be employed even when the average cruising speed is high on a high way, for example. Since the internal combustion engine 10 is employed exclusively for driving the generator 11, a small-sized light weight internal combustion engine can be employed and since it is operated at steady r.p.m., pollution due to exhaust gas can be reduced significantly.
