Title: Coating material for porous material
Inventor: NAGATANI TOSHIKAZU
IPC: C09D5/02
Filed: 1993-12-08
Abstract: PURPOSE:To obtain a water-based coating material which can be easily washed off with water when it is adhered to the inside wall or the like of a coater and is desirable to coat a porous material with a vacuum coater by adding a compound having a polymerizable double bond to a water-based emulsion coating material. CONSTITUTION:A water-based emulsion coating material is produced by, for example, melting an epoxy resin by heating or dissolving the resin in an organic solvent and forcibly emulsifying the melt or the solution in water. The obtained coating material is mixed with a compound having a polymerizable double bond as the essential components to produce the objective material. Example of the above compound include an ester of (meth)-acrylic acid with a 1-26C monoalcohol and a mono- or di-ester of (meth)acrylic acid with a 2-26C dihydric alcohol (e.g. polyethylene glycol diacrylate). Even when this coating material is adhered to the inside wall or the like of a vacuum coater and the water is evaporated, it can be removed merely by water injection.

Filed: 1989-12-29
Abstract: PURPOSE:To make the display state of a cursor variable according to the input state of data by providing a second display control means flashing the display of the cursor after the lapse of a fixed period is detected by a time detecting means. CONSTITUTION:Every time key entry is provided from a key input means 1, the current time is obtained by a clock circuit and stored into the time detecting means 2 as final key entry time. The final key entry time is compared with the current time at every fixed timing, whereby the lapse of the fixed period is detected. At this time, when the fixed period is, e.g., 10 secs., a first display control means 3 continues the flashing display of the cursor until the 10 secs. lapse since the final key entry time, whereas if data entry is transiently interruptted and the time detecting means 2 detects that the fixed period, i.e., the 10 secs. lapse since the final entry time, the second display means 4 continues the flashing display of the cursor afterward. Thus, the display state of the cursor can be changed according to the input state of the data.
