Patent number: 8597483Abstract: In a method for making a wave-absorbing sheet, first emulsified mixture is provided by mixing wave-absorbing particles with graphene solution so that the graphene solution absorbs the wave-absorbing particles. Secondly, second emulsified mixture is provided by adding and blending resin solution in the first emulsified mixture. Thirdly, third emulsified mixture is provided by adding and blending interface modifier in the second emulsified mixture. Then, two conductive substrates are submerged in the third emulsified mixture, and voltage is provided to the third emulsified mixture so that the wave-absorbing particles, the resin solution and the graphene solution are evenly coated on the conductive substrates. Then, a wave-absorbing sheet is provided by eroding and removing the conductive substrates. Finally, the wave-absorbing sheet is washed and dried. The wave-absorbing sheet is thin, light and flexible, and exhibits a wide absorption frequency band and a high absorption rate.Type: GrantFiled: April 24, 2012Date of Patent: December 3, 2013Assignee: Chung-Shan Institute of Science and Technology, Armaments, Bureau, Ministry of National DefenseInventors: Yen-Chung Chen, Ker-Jer Huang, Chien-Chih Kung, Shang-Wanq Yeh

Patent number: 8567385Abstract: A fret saw includes a cutting wire and fixed abrasive grains provided on the cutting wire by electroplating. Each of the fixed abrasive grains includes a core and a hard film coated on the core. The core is 1 to 60 micrometers in diameter. The core is made of a material selected from the group consisting of a Ti metal and a Ti alloy. The hard film is 1 to 40 micrometers thick. The hard film covers about 30% to 90% of the surface of the core.Type: GrantFiled: September 22, 2011Date of Patent: October 29, 2013Assignee: Chung-Shan Institute of Science and Technology, Armaments, Bureau, Ministry of National DefenseInventors: Chien-Chih Kung, Ching-Yu Tso, Shang-Wanq Yeh, Hsiou-Jeng Shy

Publication number: 20120060708Abstract: The invention discloses a metal pattern formation system produced in the following steps: an organic liquid is first printed on a substrate to form a base pattern. A metal is then evaporated to generate several metal particles for covering the printed substrate. At last, the substrate is heated to vaporize the base pattern, and the metal particles adhered to the substrate forms a metal pattern complementary to the base pattern.Type: ApplicationFiled: September 23, 2011Publication date: March 15, 2012Inventors: Li-Jiuan Chen, Chien-Ho Huang, Hsiou-Jeng Shy, Shang-Wanq Yeh, Ching-Yu Tso
