Title: Resin bond wheel
Inventor: NAKAMORI NOBUO
IPC: B24D3/28
Filed: 1987-02-16
Abstract: PURPOSE:To aim at the promotion of long service life, by using a spherical glass bead, whose surface is smooth enough, as a filler. CONSTITUTION:Glass is one that is suitable for a filler for resin formation if a proper type of composition, specific gravity, hardness or the like is selected, but in this case, a spherical bead, whose surface is smooth enough, is used in particular. Since this sphere has no projecting angle or ridge, stress distribution in a resin compact filled with this bead is gentle enough and there is no speed variation, therefore stress is not abnormally concentrated. Since mixture with resin powder before compaction is carried out so smoothly because of smoothness on the surface, a fact that this resin powder is uniformly dispersed in the compact is conductive to a relief of stress distribution. Accordingly, in this resin compact, any weak point attributable to a cause of abrasive grain falling is largely restrained, so that a grinding wheel bonding this comes to such one that is high in a utilization factor of diamond or CBN abrasive grains in addition to long service life.

Title: Wearability testing method for thermosetting resin molding material
Inventor: MORIKAWA KENJI
IPC: G01N3/56
Filed: 1980-03-15
Abstract: PURPOSE:To estimate the wear degree of screw, cylinder and the like at molding, in a short period of time, by a method wherein a nozzle tip of soft metal is detachably attached to the end of the cylinder of an injection molder, and after a given number of times of injection of thermosetting resin, the wear degee of the nozzle tip is measured. CONSTITUTION:To predict the wear degree of an injection molder using a thermosetting molding material containing a filler such as silica, a nozzle tip 2 formed of a soft metal such as brass or soft steel is detachably attached to the end of an injection nozzle main body 1 through a screw portion 4. After a given number of times of injection (e.g., 100 shots) of the molding material under the same temperature and pressure conditions as the actual molding, the nozzle tip 2 is removed, and the wear degree is calculated from the weight difference between before and after the injection. Said value is compared with the value previously measured in the actual molding to predict the wearability of the thermosetting resin in a short period of time. Thereby, highly reliable prediction can be readily performed.

Title: Pigment composition
Inventor: HIRASAWA YUJI
IPC: C09B67/48
Filed: 1991-02-01
Abstract: PURPOSE:To obtain a pigment composition which, when added to a nonaqueous vehicle, can give a dispersion having good agglomeration resistance, crystal growth resistance, stability and flow by kneading a dioxazine pigment with a specified dioxazine pigment derivative. CONSTITUTION:A dioxazine pigment is kneaded with 0.1-30wt.% dioxazine pigment derivative of formula I (wherein X is halogen, SO3H, NO2 or NH2; (m) is 0 or 1-4; and (n) is 1-4), e.g. a compound of formula II or III, to obtain a pigment composition. This composition neither undergoes crystal transition and growth in an aromatic solvent at ordinary temperature to 160 deg.C nor changes in hue and tinting strength. When compared with the case in which the dioxazine pigment is used alone, it has good dispersiblity in a nonaqueous vehicle such as a coating material or a gravure ink, does not agglomerate and gives good flow. Even when it is used in the form of a mixture with a different pigment, it undergoes neither segregation nor settlement, and therefore can give a colored polymer which can give a print or a coating film which is beautiful and has a good gloss.
