摘要:
A tube chemical vapor deposition method of preparing titanium carbide/silicon nitride (TiC/Si.sub.3 N.sub.4) composites. To prepare such composites, titanium carbide (TiC) is first coated with a homogeneous layer of titanium nitride (Ti.sub.3 N.sub.4). A gas mixture of titanium chloride (TiCl.sub.4), nitrogen (N.sub.2), hydrogen (H.sub.2) with an appropriate ratio is introduced into a reaction chamber where the tube chemical vapor deposition takes place. The temperature of the reaction for the sintering process is between 900.degree. C. to 1200.degree. C., under a total pressure of 1 atm. While maintaining a constant temperature for 1 to 2 hours, deposition of titanium nitride (Ti.sub.3 N.sub.4) onto titanium carbide (TiC) powder takes place. The adoption of the simple tube chemical vapor deposition technique for the present invention not only enables a mass production of homogeneously coated titanium carbide (TiC) particulates, but also further enhances the hardness and toughness as well as other mechanical properties of silicon based composites, such as a titanium carbide/silicon nitride (TiC/Si.sub.3 N.sub.4) composite.

摘要:
A sealed electric switch assembly comprises a magnetic control assembly having first and second magnetic members which is mounted to a top wall of a sealed casing, and an elongated plate having third and fourth magnetic members which is mounted oppositely to the first and second magnetic members so that the elongated plate member can be attracted and repulsed magnetically by the magnetic control assembly. A linkage mechanism is mounted adjacent to the elongated plate member for moving a movable contact of a movable arm to connect and disconnect with a stationary contact. A rotary assembly and a tripping assembly are mounted above the linkage mechanism and over an electromagnet.

摘要:
A method for fabricating a non-volatile memory is provided. A stacked structure including a tunneling layer, a trapping layer, a barrier layer, and a control gate is formed on a substrate. A source region and a drain region are formed beside the stacked structure in the substrate. A silicon oxide spacer is formed on the sidewalls of the stacked structure. An ultraviolet-resistant lining layer is formed on the surfaces of the substrate and the stacked structure to prevent the ultraviolet light from penetrating into the trapping layer. A dielectric layer is formed on the ultraviolet-resistant lining layer. A contact being electrically connected to the control gate is formed in the dielectric layer. A conducting line electrically connected to the contact is formed on the dielectric layer. A lost-surface-charge lining layer is formed on the surfaces of the dielectric layer and the conducting line to reduce the antenna effect.
