Title: Formation of ceramic coating film with chemical coating film as underlayer
Inventor: KAMOGAWA TAKAKO
IPC: B32B18/00
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To efficiently form ceramic coating film excellent in appearance and uniformity by forming chemical coating film on an Al substrate and subjecting the substrate to spark discharge in an electrolytic bath. SOLUTION: A corrosion resistant chemical coating film is formed on an Al substrate by chemical treatment such as chromating and the substrate is washed, well dried and subjected to spark discharge in an electrolytic bath to form the objective ceramic coating film on the chemical coating film. An aq. soln. contg. a water-soluble or colloiclal silicate, etc., is used as the electrolytic bath. The spark discharge is preferably carried out at 15-6 deg.C. In the case of <15 deg.C, the rate of film formation decreases. In the case of >60 deg.C, the formed coating film is liable to become ununiform. The wave-form of a rectifier is preferably made serrate so as to form a more uniform coating film. Film formation time is shortened and the resultant coating film has fine appearance.

Title: Ink jet recorder
Inventor: AOKI ATSUSHI
IPC: B41J2/045
Filed: 1985-11-15
Abstract: PURPOSE:To realize an ink jet recorder having excellent response characteristics and ejection stability, by providing a member having a surface inclined at a specified angle on the side of an ejecting member to thereby absorb a pressure wave which would otherwise be propagated even to an ink-supplying passage on the downstream side. CONSTITUTION:In the figure, A denotes the ink side while B denotes the filter side. Assuming that the velocity of sound in an ink is CA, the density of the ink is rhoA, the velocity of sound in a filter 6 is CB and the density of the filter 6 is rhoB, a pressure wave (w) propagated through the ink is projected on the filter 6 at an incident angle thetaA which it forms with the normal (h) to the front surface of the filter 6. When the velocities of sound in the ink and the filter and the densities of the ink and the filter are known, the angle thetaA at which the pressure wave is not reflected can be calculated by substituting the known values for their symbols in the equation. The density of the ink and the velocity of sound in the ink can be controlled mainly by appropriately selecting the composition of a water-soluble solvent contained in the ink.
