Title: Exhaust gas particulate purification device of diesel engine
Inventor: YUZURIHA YASUHIRO
IPC: F01N3/02
Filed: 1990-01-10
Abstract: PURPOSE:To prevent occurrence of residual combustible particulates on a portion where irradiation density of high frequency is unsatisfactory by forming a catalyst layer which lowers a combustion starting temperature on an exhaust gas inlet side end face of a filter distant from a transmitting means. CONSTITUTION:An exhaust gas particulate purification device 11 has a filter 17 which captures particulates in exhaust gas and a transmitting means made up of a magnetron transmitter 15 which combusts the particulates and reactivates the filter 17 and a waveguide 16. A catalyst layer 17c which lowers a combustion starting temperature of the particulates is formed on a portion of an exhaust gas inlet side end face 17a, distant from the transmitting means. The lowered combustion starting temperature of the particulates in the vicinity of the end face 17a owing to the catalyst layer 17c makes up for unsatisfactory heating due to lack of irradiation of high frequency from the transmitting means. Occurrence of residual combustible particulates is prevented, and the filter 17 can be evenly reactivated.

Title: Developing device
Inventor: ENOKI SHIGEKAZU
IPC: G03G15/09
Filed: 1981-01-12
Abstract: PURPOSE:To improve copying quality by preventing the blocking of a doctor gap due to foreign matter contained in a high-resistance magnetic toner, by providing a foreign-matter removing member whose tip is formed in a loop shape. CONSTITUTION:A foreign-matter removing member 13 whose tips are formed in a loop shape is provided closely to a rotary sleeve 3. When high-resistance magnetic toner on the sleeve 3 is carried onto the removing member 13, the magnetic toner is napped by the notched part 9a of a permanent magnet 9. This magnetic toner, when passing by the removing member 13, passes through a loop freely, but fibrous foreign matter contained in the magnetic toner is brushed off by the loop parts. Therefore, the blocking of a doctor gap due to the foreign matter is prevented and copying quality is improved.

Title: Plasma etching method
Inventor: SHIBAGAKI MASAHIRO
IPC: H01L21/302
Filed: 1980-01-17
Abstract: PURPOSE:To perform plasma etching with excellent reproducibility on a cathode plate connected with a high-frequency power source and provided with a sheet containing C on the surface thereof by pouring CF4 to which a prescribed amount of Cl2 is added and applying high-frequency discharge between parallel-plate electrodes. CONSTITUTION:With an anode 14 formed monolithically with a vacuum vessel 15 grounded, high-frequency power is applied to a parallel cathode plate 13, a gas of CF4+Cl2 (having the concentration of 20% or more) is introduced and activated by glow discharge to generate plasma, and by using positive ions, the laminate substance 16 of Si and SiO2 on a polyester sheet on the cathode plate 13 is etched. With the increase of the added quantity of C2 to a reactive gas, the speed of etching of SiO2 lowers monotonously, while the speed of etching of Si changes from rise to fall at a point where the concentration of Cl2 reaches 40%. The etching ratio of Si/SiO2 becomes large when the concentration of Cl2 is 20% or more and excellent etching can be conducted without any undercut. It is effective that the whole is covered with a teflon film 26 beforehand to prevent pollution from the anode.
