Abstract: The present invention relates to a roller skate frame. The roller skate frame includes a plate being pressing molded into a main frame of the roller skate comprising two wheel-mounting plates corresponding to each other, and a front bottom connecting face and a shoe-mounting plate connecting thereto. The front bottom connecting face and the shoe-mounting plate are spaced apart with a suitable distance. Further, the front bottom connecting plate is formed by an upper and a lower bridging plate corresponding to each other, and both of which are positioned with a fastener hole respectively.

Abstract: The present invention relates to an ice skate blade holder and blade assembly which comprises a blade holder and a blade, wherein said skate blade holder includes two pin holes respectively located at the bottom of the front and rear aspects of said blade holder. The blade is secured with the blade holder by pins and nuts extending through said pin holes. The blade has an upper and a lower portion which are adhered to each other by glue. The lower portion of the blade provided with great wear-resistant and rigid material has an elongated protrusion extending along upside. The upper portion of the blade provided with lighter aluminum material includes an accommodated slot extending along the bottom thereof and two round slots respectively located at the upper edge thereof.

Abstract: This invention is a structural improvement for an ice skate blade, where the blade holder and the blade are separate. The blade is made from a hard, wear-resistant material. The upper surface is a relatively thinner connecting surface by a roller shape forming machine. On the surface of the blade, there are several equidistant apertures. A special mold is utilized for mounting the connecting surface of the blade to the blade holder using lighter material materials, namely plastic steel. Thus, the weight reduction of the whole ice skate blade effectively improves the skaters' technique and performance and enhances market competitiveness as well.

Abstract: The present invention relates to the degradation and removal of organochlorine pesticides (OCP) from Chinese herb medicines. In this invention, gamma irradiation is used for the degradation and removal of OCP, such as Pentachloronitrobenzene, Aldrin, Lindane, Heptachlor, Endosulfan-1, Endosulfan-2, o,p?-DDD, p,p?-DDD, p,p?-DDE, and p,p?-DDT from Chinese herb medicines. The method of the present invention requires no chemical reagents, and the application of the method is not limited by the volume and morphology of the Chinese herb medicines.

Abstract: A pharmaceutical composition for boron neutron capture therapy (BNCT), and in particular for BNCT on hepatoma is disclosed. The pharmaceutical composition contains a therapeutically effective amount of triphenylboroxin (phenylboronic anhydride) as a boron source and a pharmaceutically acceptable carrier, such as lipiodol.

Abstract: A retrievable device includes a frame with an open bottom to receive therein a monitor and at least one arm with a first distal end pivotally connected to the frame and a second distal end slidably received in the passage in the monitor. The monitor is able to be slidably and pivotally received in the frame. An elastic element is securely received in the guiding tracks in the frame so that when the guiding elements of the monitor are moving inside the guiding tracks, the elastic element is able to provide a friction to stop the movement of the guiding elements to position the monitor relative to the frame.

Abstract: A nuclear medical drug for localize radiotheraphy of a tumor and methods for its preparation. The drug includes a radioactive ceramic or glass particle having biocompatiblity. Ceramic or glass particles prepared by traditional processes become radioactive particles with pure .beta.-particle-emitting radionuclides after being irradiated with an appropriate flux of neutrons. The radioactive particle with suitable particle size can then be dispersed into a contrast medium for injection or can be implanted by operation.

Abstract: The present invention discloses a boron-containing pharmaceutical composition useful in boron neutron capture therapy of hepatoma, which includes lipiodol, stibmicron boron powder, lecithin and unsaturated fatty acid. The lipiodol has a property of a high retention in hepatoma, the lecithin has a boron carrying capacity, and the unsaturated fatty acid has a function of rendering lecithin soluble in lipiodol.

Abstract: A compass for mobile parabolic antenna includes a compass sphere having a transparent shell with an elevation dial and a magnetic core encapsulated by the transparent shell with fluid filled therebetween with a bubble enclosed within the transparent shell and a directional mark pointing to a fixed direction on the magnetic core, an annular plate having a location dial and a satellite name dial provided on edges of the plate, a cover plate having a central hole and a plurality of arcuated grooves, and a base plate having a circular depression, a plurality of arcuated recesses corresponding to the grooves on the cover plate defined in the depression, and a central bore corresponding to the central hole on the cover plate so that the compass sphere can be secured within the central hole and the central bore and the annular plate can be rotatably received by the circular depression when the cover plate couples with the base plate.
