Title: Removing method for abrasive material
Inventor: TSUJINAGA KAZUNORI
IPC: H01L21/48
Filed: 1985-12-23
Abstract: PURPOSE:To make it possible to select abrasives, which have the optimum particle diameters for removing burr regardless of the distance between the pins of an IC, by performing ultrasonic wave washing after wet honing, thereby removing the clogging and attachment of the abrasives. CONSTITUTION:Ultrasonic waves are applied to a material to be treated through liquid, and the material to be treated undergos wet honing treatment. At this time, abrasives, which are clogged in fine gaps, are removed. Namely, an ultrasonic wave generator is attached in a suitable tank. The material to be treated is immersed in the tank. Water can be used as the liquid used in the ultrasonic wave washing. In the case the abrasives are rigidly clogged, it is better to use an organic solvent having light specific gravity since the more powerful ultrasonic waves can be obtained with the same output power.

Title: Transfer recording medium
Inventor: MOROHOSHI KUNICHIKA
IPC: B41M5/382
Filed: 1987-11-20
Abstract: PURPOSE:To contrive higher adhesion between an ink layer and a base while maintaining thermal sensitivity, by minutely graining a surface of a resin intermediate layer which surface makes contact with a heat-fusible ink layer, in a transfer recording medium comprising the resin intermediate layer and the ink layer on a base. CONSTITUTION:The surface of an intermediate layer is minutely grained by, for example, blushing, formation of an orange peel surface or addition of a pigment. The formation of the orange peel surface or the blushing may be carried out by lowering the temperature of a base 1 after providing the intermediate layer 2 thereon by coating, whereby condensation of moisture is caused, and the surface is deprived of gloss, resulting in blushing. The lowering of the temperature of the base may be carried out by using a quick-evaporable solvent such as methanol, acetone and toluene as a solvent of a coating material for forming the intermediate layer, causing the condensation at a high temperature, rapidly heating the base after coating to rapidly evaporating the solvent, and blowing air to the coating film, thereby roughening the film. by the method of adding a pigment, the pigment is used in an amount of 5-30wt.% based on the intermediate layer, the particle diameter of the pigment being suitably about 0.01-1mum. By this, the adhesion between an ink layer 3 and the base 1 can be enhanced without enlarging the thickness of the intermediate layer 2.
