Title: Dampening water composition for planographic printing and using method thereof
Inventor: NISHI KUNIO
IPC: B41N3/08
Filed: 1991-10-15
Abstract: PURPOSE:To prevent bacteria from generating in a dampening water supply system so as to avoid degradation of printability and failure in supplying dampening water by composing the dampening water by incorporating dissociative fluorine compound therein to such an extent that fluorine ion density becomes above a specific fluorine ion density. CONSTITUTION:In a planographic printing, dampening water is firstly given to a printing plate and a water film is formed on hydrophilic non-printing area. Next, after oil ink is transferred on lipophilic printing area, print ink image is transferred on a body to be printed so as to obtain a printed matter. In this case, the dampening water is composed by adding dissociative fluorine compound thereto. The dissociative fluorine compound of 0.01mos/l or more is added to the dampening water as a fluorine ion density. Further, the dampening water is used by diluting the fluorine non density to 1.0X10<-4>mol/l or more. Thus, mold, algae, or bacteria are prevented from generating in a circulating piping for supplying the dampening water and in a storage tank, so that degradation of printability and clogging of the piping can be avoided.

Filed: 1994-11-30
Abstract: PURPOSE: To improve the coating state of a contact via by appropriately selecting a fire-resistant metallic layer and the attachment condition of aluminum, at the time of forming the fire-resistant metallic layer on a barrier layer, and attaching and forming aluminum on this. CONSTITUTION: After a thin titanium layer 24 has been attached and formed on a device, a wafer is moved to an aluminum attachment chamber, and thin aluminum is attached at a low temperature of 0-300 deg.C. Next, the wafer is moved to another chamber having a high temperature of about 400-550 deg.C without destroying vacuum. Immediately, the aluminum is attached and formed at a relatively low attaching speed between about 20 Å/second and 50 Å/second. As a result, a further thick aluminum layer 26 is formed, and an opening 14 is packed with the layer, and a flat layer is formed across a whole chip. Thus, a coverage, that is, coating state for a contact via can be improved.

Title: Variable inductor
Inventor: ISAKA HARUO
IPC: H01F21/02
Filed: 1987-11-25
Abstract: PURPOSE:To eliminate eddy current loss for high frequencies, by disposing a superconductor approximately on a center line of a coil and by providing means for moving the superconductor on the center line. CONSTITUTION:A superconductor 2 with threads is disposed on a center line of a coil 1. The superconductor 2 is held by a support 3 of a non-magnetic material with threads. The superconductor 2 can be moved on a central line by its rotation. A magnetic field can never exist inside the superconductor 2. Therefore, when the superconductor 2 is moved toward the coil 1, the reluctance of a magnetic path formed by the coil 1 increases unlike the case of ferrite, and an inductance decreases. The eddy current loss for high frequencies is eliminated accordingly.
