Title: Production of plasticized polyvinyl acetal sheet
Inventor: YAMANE TOSHIO
IPC: C08L29/14
Filed: 1991-04-24
Abstract: PURPOSE:To produce the subject sheet containing a small amount of a highly dispersed adhesiveness-controlling agent and useful as a high quality intermediate sheet for laminated safety glass, by blending a polyvinyl acetal resin with the adhesiveness-controlling agent and a plasticizer in an extruder, while the adhesiveness-imparting agent is dissolved in water, etc., and mixed with the plasticizer under stirring. CONSTITUTION:A polyvinyl acetal resin is fed into an extruder, blended with an adhesiveness-imparting agent and a plasticizer, and subsequently melt- extruded into a sheet. In the process, the adhesiveness-imparting agent and the plasticizer are fed into the extruder, while the adhesiveness-imparting agent is dissolved in an organic solvent or water and mixed with the plasticizer with stirring. The resin is preferably polybutyral resin having a butyralization degree of 60-70mol.% and an average polymerization degree of 1000-2000. The adhesiveness-imparting agent is preferably an alkali (alkaline earth) metal salt of acetic acid, etc., and used in an amout of 0.01-0.5 pts.wt. per 100 pts.wt. of the resin.

Title: Inspection method for wiring base plate copper layer surface and production method for the wiring base plate
Inventor: NAMIKI TAKAHISA
IPC: G01B11/06
Filed: 1993-04-21
Abstract: PURPOSE:To prevent the peeling of resist and the invading of plating under the resist by emitting light to a circuit base plate copper layer surface and measuring the progession of copper layer surface oxidation with the use of the reflected light. CONSTITUTION:When oxidized copper coating film 3 is formed due to the oxidation of the surface of copper layer 2 on a circuit base plate 1, resit 4 is painted for patterning and then etching or plating is applied. At this time, because of higher solubility of oxidized copper than copper in acid or alkali, the oxidized copper coating film under the resist is solved by the etching liquid or plating liquid and so invading 5 of the etching liquid and plating liquid under the resist occurs. By irradiating light on the surface of copper layer 2 on the circuit base plate 1 and making use of the reflection light, the progression of copper layer surface oxidation is measured. With the progression of oxidation on copper film, the bright yellow gradually changes to red and not only hue but also the reflection characteristics for visible light and ultraviolet and chroma change. Therefore, by monitoring this, the progression of oxidation and the thickness of the copper film can be measured.

Title: Automatic screwing machine
Inventor: SHIMURA TAKAFUMI
IPC: B23P19/06
Filed: 1984-05-11
Abstract: PURPOSE:To reduce tube movements by half as well as to aim at miniaturization, by setting up a timing belt, whose one side is locked to a fixed base and a driver to the other side, respectively, in a rotatable pulley at both ends of a tube moving up and down with a fixed base shaft as the shaft center. CONSTITUTION:When air enters out of an air port 3, it passes through a rod 4 and flows into a tube 5, and the tube 5 goes down with the rod 4 as the shaft center due to air pressure whereby a bracket 6 also goes down. At this time, since a timing belt 7 is checked of its movement by a fixed bracket 8 and a fixed plate 9, a pulley 10 goes down as being rotated, and since a DV holder 11 is also locked to the belt 7 by a fixed plate 12, it also goes down together. Here at, the fixed plate 12 moves as many as twice a travel distance of the pullery 10 so that the DV holder 11 moves as many as two times over the tube 5. And simultaneously with a descent of the holder 11, a screwdriver 13 goes down and screws down. Thus, tube movements become halved to a screwing stroke so that a screwing machine is miniaturized.
