Abstract: A novel therapeutic agent for solid cancer capable of hardening the cellular tissue itself of a solid cancer to induce death or growth inhibition of cancer cells, causing solidification of the tissue, is disclosed. The therapeutic agent for solid cancer is composed of a liquid composition containing as an active component an ethoxy-containing compound capable of undergoing polycondensation in a cellular tissue. The therapeutic agent for solid cancer is capable of hardening the cellular tissue itself of a solid cancer such as lung cancer to induce death or growth inhibition of cancer cells, causing solidification of the tissue. In conventional therapeutic methods, the risk of metastasis due to spreading of cancer cells through the bloodstream cannot be eliminated. In contrast, this therapeutic agent for solid cancer instantly surrounds cancer cells, so that the risk of metastasis can be largely reduced.

Abstract: A remote control system capable of precise operations or treatments in which the visual recognition and operation portions are as close to each other as possible, including: a) an imaging device for taking an image of the object; b) a manipulation tool having at its tip an illuminator for casting a spot light onto the object; c) a driver for changing the position of the manipulation tool; d) an external display unit for displaying an image; e) an input unit for allowing an operator to specify a position corresponding to the display of the external display unit; f) a distance calculator for calculating the distance between the position specified through the input unit and the position of the spot light cast from the illuminator onto the object; and g) a controller for controlling, based on the aforementioned distance, the driver so as to bring the tip of the manipulation tool closer to the specified position.

Abstract: The present invention is achieved with the object of providing an illumination system formed of an LED light emitting body and a socket which can appropriately release heat from LED chips. This object is achieved in the following manner. A heat conducting layer 12 made of diamond is provided on a substrate 11, and on top of this, a conductive layer 13 having a predetermined pattern is formed. LED chips 16 are mounted in predetermined positions on the conductive layer 13. Terminals of the conductive layer 13 and electrodes of the LED chips 16 are connected to each other. A connector part 14 for the connection to a socket is provided in an end portion of the substrate 11. The heat conducting layer 12 on the connector part 14 makes thermal contact with the heat conducting layer provided on the inner surface of the opening of the socket. A current is supplied to respective LED chips 16 through the conductive layer 13 from the socket, and respective LED chips 16 emit light.
