Title: Ceramic cloisonne ware for flower arrangement
Inventor: SHIMIZU KIYOSHI
IPC: A47G7/02
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain a cloisonne ware by which water is kept from becoming foul even if it is put in a flower bowl at the time of arranging flowers by containing specified quantities of red oxide, iron oxide and manganese dioxide in potter's clay containing the respective specified quantities of alumina, silica, sodium, and potassium. SOLUTION: Potter's clay used is composed of 15-30wt.% alumina, 50-80wt.% silica, 0.1-1.5wt.% sodium and 3-7wt.% potassium, and 12-15g red oxide, 8-10g iron oxide formed by a crop, and 3-5g manganese dioxide are contained in 100g potter's clay. A cloisonne ware S for flower arrangement is creased by the above material. This ceramic cloisonne ware S generates a large amount of far infrared rays, so that when the above cloisonne ware is put in a flower bowl filled with water for flower arrangement, germination and growth of plants can be promoted by the effect of warming water and the effect of warming the inside of the arranged flowers. Further, the water can be prevented from becoming foul by the purifying action on water produced by the effect of thermal energy and electromagnetic waves.

Title: Engine provided with supercharger
Inventor: MASUDA SHIYOUJI
IPC: F02M35/10
Filed: 1983-04-13
Abstract: PURPOSE:To reduce the cost of an engine provided with a supercharger, to which no consideration is necessary to provide its carburettor with air-tightness, by disposing the carburettor in a pressurized air passage from the supercharger. CONSTITUTION:Air from an air-cleaner 3 is pressurized by a supercharger 3 and enters in a surge tank 5 in which carburettor 2 having a suction port 2a is incorporated. Therefore, the pressurized air enters into the carburettor 2 through the suction port 2a to form a mixture which is then fed into an engine. Since the carburettor 2 is completely disposed in a pressurized intake-air passage such as, for example, the surge tank 5, so that the inside and outside pressures of the carburettor 2 are equal together, and therefore, it is not necessary to provide a seal means for preventing the pressurized air in the carburettor from leaking outside of the latter.
