Patent CA-2341736-A1 (CA)
Title: Surface-mounted antenna and communication device compprising the antenna
Inventor: NAGUMO SHOJI
IPC: H01Q5/10
Filed: 2000-09-08
Abstract: A parasitic radiation electrode (3) and a driven radiation electrode (4) are  formed at an interval on the surface of a dielectric base (2). A material (8 ) for permittivity adjustment is provided in an interval (S) between the parasitic radiation electrode (3) and the driven radiation electrode (4) whe re capacitance is created. The material (8) for permittivity adjustment has a lower permittivity than the dielectric base (2), so that the permittivity between the parasitic radiation electrode (3) and the driven radiation electrode (4) is below the permittivity of the dielectric base (2), reducing  the capacitive coupling between the parasitic radiation electrode (3) and th e driven radiation electrode (4).As a result, the resonance interaction betwee n the parasitic radiation electrode (3) and the driven radiation electrode (4)  decreases, thus improving antenna performance, without taking measures, such  as an increase in the interval (S) between the parasitic radiation electrode  (3) and the driven radiation electrode (4) and a decrease in permittivity of  the dielectric bases (2), which may obstruct the miniaturization of a surfac e- mount antenna (1).

Patent CA-2351745-A1 (CA)
Inventor: VADDI BUTCHI REDDY
IPC: H05B33/14
Filed: 2001-06-26
Abstract: An electroluminescent phosphor with an increased efficiency is created by blending a chloride flux, a copper source and a zinc sulfide to form a mixture and then heating the mixture for a period of time, cooling the mixture, and washing it with de-ionized water. The mixture is dried and milled to form cubic ZnS from hexagonal ZnS, forming a beginning uncoated ZnS:Cu,Cl electroluminescent phosphor. This beginning phosphor is added to other materials, including Ga2O3, forming a second step material (SSM). The SSM is placed into a first vessel, such as a plastic bottle, blended, sifted and then placed in a second inert reaction vessel that is then heated for a period of time. After cooling, the fired SSM is washed with de-ionized water, washed with acetic acid, again washed with de-ionized water to remove residual acid, washed with KCN and again with de-ionized water to remove residual KCN. The fired and washed SSM is then dried, filtered and sifted, producing a new phosphor with an increased efficiency.

Title: Method of cryopreservation of blood vessels by vitrification
Inventor: BROCKBANK KELVIN G M
IPC: A61K35/44
Filed: 2000-04-12
Abstract: A method for vitrification of a blood vessel includes immersing the blood vessel in increasing concentrations of cryoprotectant solution at a temperature greater than -15 ~C to a cryoprotectant concentration sufficient for vitrification; cooling the blood vessel at an average rate of from 30-60 ~C per minute to a temperature between -80 ~C and the glass transition temperature; and further cooling the blood vessel at an average rate less than 10 ~C per minute to a temperature below the glass transition temperature to vitrify the blood vessel. After the vitrified blood vessel has been stored, the blood vessel may be removed from vitrification by warming the blood vessel at an average rate of from 20-40 ~C per minute to a temperature between -80 ~C  and the glass transition temperature; further warming the blood vessel at a rate of from 200-300 ~C per minute to a temperature above -15 ~C; and reducing the concentration of the cryoprotectant. Blood vessels treated in this manner exhibit near normal smooth muscle function, normal graft patency rates, and reduced levels of intimal hyperplasia.
