Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To prevent a guard fence from dirt of smoke, etc., by forming a surface layer containing photocatalystic particles, silicon and water repellent fluororesin on the surface of a guard fence basic material. SOLUTION: A surface layer containing photocatalystic particles, silicon and water repellent fluororesin is formed on the surface of a guard fence basic material.

Then, by the existence of photocatalyst, construction dispersing microscopically both of part showing hydrophile and part showing water repellingness to the surface is maintained, and since hydrophilic adherend and hydrophobic adherend are not made to adhere to the surface of the member, the surface is maintained in a clear state.

Title: Toner jet recorder
Inventor: IWAO NAOTO
IPC: B41J2/415
Filed: 1990-10-29
Abstract: PURPOSE:To prevent the clog of an aperture part uniformly and effectively to obtain a constantly stable image output by a method wherein a vibration excited by an exciting device is a progressive wave transmitting on an aperture electrode. CONSTITUTION:When an electric signal of a predetermined frequency fr[kHz] is applied from a drive circuit 31 to an exciting body 21 at the time of image forming, an aperture electrode 1 is excited by a bending vibration. This vibration is transmitted in a direction X, and the transmitted vibration reaches the other end of the aperture electrode 1. At this time, the vibration energy is absorbed by a reflection wave absorber 22. Thus, a reflection wave is not generated, but a progressive wave advancing in the direction X, i.e., toward an aperture train 12, is generated on the aperture electrode 1. A sufficient vibration amplitude is obtained at an aperture 11 provided at any position on the aperture electrode 1. At a position of every aperture 11, a maximum vibration acceleration can be obtained. In this manner, a toner is not applied to the apertures 11 and thereabouts of the aperture electrode 1, and the apertures 11 are prevented from clogging.

Abstract: PURPOSE: To suppress the formation of a parasitic device between diffusion areas and to shallow trerach separation structure by electrically connecting an N type diffusion area to a P type diffusion area through a conductor filling trench arranged between both the areas. CONSTITUTION: The filling trench 100 is arranged between the P type diffusion area 54 and the N type diffusion area 62 and a conductive layer 120 formed in the trench 100 electrically connects both the areas 54, 62. The conductor layer 120 is insulated from a substrate 70 by thin dielectric structure 110. The electric connection between the areas 54, 62 and the layer 120 is executed by sticking the conductive layer 120 to the surface of the substrate 70 and etching the layer 120 or sticking a fire resisting metallic layer to the surface under a condition for accelerating the growth of cylindrical crystal grains, sintering the metallic layer and forming silicon titanium on the upper part of the layer 110. Consequently the formation of a parasitic device between both the diffusion areas can be suppressed and the dielectric structure can be thinned.

Filed: 1985-12-24
Abstract: PURPOSE:To eliminate head clogging and to improve recording and reproducing characteristics by disposing a photopolymerizable resin to part of a surface of a nonmagnetic material to face a magnetic recording medium in contact therewith. CONSTITUTION:A magnetic circuit part is constituted on a lower magnetic material 1 by successively laminating a coil conductor 2 and upper magnetic film 3 respectively via insulating layers 4, 5 on said material to form a thin film magnetic head element 6. A protective part 7 consisting of the photopolymerizable resin is formed on such thin film magnetic head element 6.
