    摘要: A method capable of synthesizing carbon nanotubes at low cost and large quantities, an apparatus usable for carrying out the method, and carbon nanotubes densely aligned on and firmly bonded to a Si substrate over, and oriented perpendicular to, an entire surface thereof are provided. Highly oriented, aligned carbon nanotubes are synthesized from an organic liquid by forming a substrate with a buildup thereon of a thin film or fine insular particles composed of at least one metallic element; exposing the substrate (3) having the buildup to a hydrogen plasma; and heating the substrate (3) exposed to the hydrogen plasma in the organic liquid (10) to a predetermined temperature. The synthesis apparatus comprises: a liquid chamber or tank (1) for an organic liquid; a water cooling means (2) for cooling the liquid tank (1) from its outside; a substrate holder (5) for holding a substrate (3), the holder having electrodes (4) for passing an electric current through the substrate (3); a condensing means (7) comprising water cooling tubes (6) for cooling and condensing vapor made from the organic liquid by its vaporization to return it to the liquid for return into the liquid tank (1); a valve (8) through which N2 gas is introduced; and a lid (9) that carries the substrate holder (5), the condensing means (7) and the valve (8). The organic liquid (10) is thus tightly sealed in the liquid tank (1) by the lid (9). This synthesis apparatus allows carbon nanotubes to be synthesized in large quantities, at low cost and in safety. Highly coaxially and densely oriented, aligned carbon nanotubes can be synthesized in the form of a bundle thereof, which when used in a variety of products brings about various excellent effects including extremely high usability.

    摘要: 3C-SiC nanowhisker and a method of synthesizing 3C-SiC nanowhisker wherein its diameter and length can be controlled. The method is safe and low cost, and the whisker can emit visible light of various wavelengths. 3C-SiC nanowhisker is formed by depositing thin film (2) made of a metal element on Si substrate (1), placing this Si substrate (1) into a plasma CVD apparatus, and holding it for predetermined time at predetermined substrate temperature in the plasma consisting of hydrogen and hydrocarbon. Si of Si substrate (1) and C in plasma dissolve at supersaturation into metal liquid particles (3), 3C-SiC nanowhisker (4) grows on the metal liquid particles (3), whisker surface is terminated with H so as to maintain the diameter constant, and the metal liquid particles (3) at whisker root take in Si from Si substrate (1) and penetrate into Si substrate (1).

    摘要: A method protects a daemon in an operating system of a host computer. The operating system detects that there is an access of a plist file of a daemon by a process in the computer. If so, then it executes a callback function registered for the plist file. The callback function sends to a kernel extension a notification of the attempted access. The kernel extension returns a value to the operating system indicating that the access should be denied. The operating system denies access to the plist file of the daemon by the process. The extension may also notify an application which prompts the user for instruction. The kernel extension also protects itself by executing its exit function when a command is given to unload the extension, and the exit function determines whether or not the command is invoked by an authorized application, such as by checking a flag.
