Title: Method for forming wiring pattern
Inventor: TOYODA YUJI
IPC: G03F7/26
Filed: 1998-11-25
Abstract: PROBLEM TO BE SOLVED: To form further precise wiring pattern by the lift-off method by getting rid of critical factors in the lift-off method. SOLUTION: A resist pattern 12 is formed on a substrate 11. By using a photomask with a pattern that has a line width being equal to or less than a resolution limit for the surface of the resist pattern 12, a groove (dummy pattern) with a depth that does not reach the substrate 11 is formed, and the volume of the resist pattern 12 is reduced. Furthermore, by baking the resist pattern, gas is discharged from the resist pattern and an electrode material is formed on the substrate at a temperature lower than the baking temperature. Also, when the electrode material is formed, film formation properties can be improved by cooling a substrate holder.

Title: Sound absorbing structural body
Inventor: IBUSUKI AKITSUGU
IPC: B01J35/02
Filed: 1995-12-22
Abstract: PROBLEM TO BE SOLVED: To reduce the noise and reduce nitrogen oxides. SOLUTION: By using a sound absorbing structural body having a sound absorbing body 1 consisting of a porous material 12 carrying titanium dioxide 13 so that the sound absorbing body 1 can be irradiated with light, noise associated with the traveling of vehicle or the like is absorbed by the sound absorbing body 1 and is reduced, and air near the earth's surface in which many nitrogen oxides exist flies up by wind pressure associated with the traveling of vehicles and the like and is conveyed to the sound absorbing body 1. On the other hand, the titanium dioxide 13 carried by the sound absorbing body 1 is activated by the irradiation of light. And when the nitrogen dioxide in air conveyed by the sound absorbing body 1 comes into contact with the activated titanium dioxide 13, the nitrogen dioxide is removed by strong oxidizing capacity due to the activity of the titanium dioxide 13.  Besides, since the titanium dioxide 13 is carried by the sound absorbing body 1 consisting of a porous material having large surface area, the surface area of the titanium dioxide 13 in contact with air is large to effectively remove the nitrogen oxides.

Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To improve the contrast by forming a diffusing layer only in the region where bright beams transmit except for the region where black stripes are formed. SOLUTION: Black stripes 14 are formed except for the region where light beams are condensed and transmitted on the flat face of a lenticular screen, and a diffusion treatment layer 15 is formed only in the region where the light is condensed and transmitted when the lens is viewed from the flat face. As for the formation of the black stripes 14 and the diffusion treatment layer 15, the black stripes 14 are formed except for the region where the light is condensed by using the condensing characteristics of the lens to avoid reflection of external light. Practically, an intermediate layer is formed from an ink prepared from silicon resin fine particles as the diffusing agent between photosensitive material layers 16.  The photosensitive layers 16 with the diffusion treatment layer 15 inserted are laminated to the opposite face of a lens supporting body 11 to the face where the lens face is formed. Then the layers are irradiated with UV rays through the lens to condense the light to harden the bright beam region, while other regions are not hardened. Then an ink transfer foil is transferred to the region where the layers are not hardened so as to form the black stripes 14.
