Title: Theoretical structure of article judgment and authentication of handled article in electronic commerce
Inventor: SUZUKI KATSUHARU
IPC: G06Q50/10
Filed: 2000-03-13
Abstract: PROBLEM TO BE SOLVED: To accelerate the development of electronic commerce expected to spread in future by eliminating many troubles resulting from that an article can not be confirmed because of a virtual space as much as possible. SOLUTION: Although the electronic commerce is very superior in convenience in buying an article, a purchase wisher is unable to confirm the article and doubts about its safety and reliability judging from the possibility of a swindle, a purchase of a defective, and the selling of an article different from display. Even in such a case, the electronic commerce running company is not responsible so far for an article purchase which is disadvantageous to the purchaser. A procedure for a trial is introduced as a postprocess and when the seller exhibits an article with the same name, purchaser's attention is drawn, but little effect is expected. Here, this system theoretical structure authenticates an article for sale and judges the current value of the article by cooperating or making an exclusive contract with an expert in price judgment and notifies an article purchase wisher of it.  This invention which gives limitless safety and reliability to the electronic commerce is considered to greatly contribute to the expansion of the electronic commerce.

Title: Flow rate restricting drip chamber for intravenous drip injection and supply system
Inventor: HECTOR URRUTIA
IPC: A61M5/00
Filed: 2000-05-10
Abstract: PROBLEM TO BE SOLVED: To provide a drip chamber minimizing the generation of an air bubble in an intravenous drip injection and supply system. SOLUTION: A drip chamber 16 has a housing 24 having an inflow port 26 and an outflow port 28 and demarcating a chamber 30 between the inflow and outflow ports. The housing 24 is constituted so that an intravenous drip injection liquid passes through the chamber from the inflow port to flow to the outflow port. The member 38 supported at the position between the inflow port and outflow port in the chamber is arranged so that the intravenous drip injection liquid impinges against the member 38 and lowers the speed of the intravenous drip injection liquid to minimize the generation of an air bubble in the intravenous drip injection liquid.  Since the inner diameter of the inflow port is substantially equal to or larger than that of the outflow port, the flow rate of the intravenous drip injection liquid issuing from the outflow port is substantially equal to or smaller than that of the intravenous drip injection liquid entering the inflow port.
