Title: Gap forming method of magnetic head
Inventor: OGASAWARA SHIYUUJI
IPC: G11B5/133
Filed: 1983-12-23
Abstract: PURPOSE:To obtain a magnetic head having coincidence with a magnetic gap set initially by butting both ferrite matters against each other after polishing both butting faces with high accuracy and forming the magnetic gap after removing the ferrite layer deteriorated by processing by a dry etching process. CONSTITUTION:The butting faces 11a, 12a and gap forming faces 11b, 12b of the 1st and 2nd ferrite blocks 11 and 12 are polished sufficiently with high accuracy to obtain a ferrite core. Then a layer deteriorated by processing and existing at least on the face 11b at one side is removed. At the same time, a dry etching process is applied to obtain a desired gap size through the stage processing. Thus a groove is obtained with the width layer than the prescribed track width. Then both blocks 11 and 12 are butted against each other through faces 11a and 12a with application of pressure. Then glass if filled between faces 11b and 12b to form a gap (g), and the junction block is cut with desired track width to obtain a prescribed core chip.

Title: Manufacture of colored particle board
Inventor: SHIMIZU SHIN
IPC: B27N3/02
Filed: 1984-11-29
Abstract: PURPOSE:To make it possible to omit a step of immersing chips in a colorant liquid, a drying step, and other steps, by mixing previously a colorant with a binder before the binder are mixed with the vegetable chips or mixing a colorant and a binder separately with vegetable chips. CONSTITUTION:The reason why a self-emulsifiable isocyanate compound is excellent as binder is that the allowable range of water content of chips is wider than other binders, and the heating time under pressure may be shortened. The obtained colored particle board is excellent in fixed color stability and has favorable properties such as antidiscoloration in water. As a self-emulsifiable isocyanate compound is of a water dispersable type, the workability during the production is good, and it can be used with other water-based binder or replaced thereby easily. Since the colorant and the binder can be used as a mixture or can separately be added to vegetable chips, the dipping of vegetable chips in the colorant liquid or the subsequent drying step can be omitted.
