Filed: 1980-06-16
Abstract: PURPOSE: To bond hard grinding particles to one another tightly and also to bond a layer of such grinding particles to a vitrified grinding stone support body tightly by a method wherein the bonding surface on which the layer of the grinding particles is formed is coated with a liquid phase thermosetting resin and the resin is  hardened by heating so that the resin becomes a resinoid bond to thereby bond the  layer tightly to the support body.  
     CONSTITUTION: The surface of the vitrified grindstone support 11 on which the layer 12 of the hard grinding particles is formed is coated with the liquid phase thermosetting resin and the resin is hardened by heating so that a resinoid saturated layer 11a is formed on the surface of the support body 11. Then a mixture of the hard grinding particles 13 made of cubic boron nitride (or those mixed with a filler) and a thermosetting resin 14 is pressure molded to form a layer thereof on the support body 11 and the molded layer is heated with the result that the support body 11 and the hard grinding particles 13 and the grinding particles themselves are bonded together tightly through the thermosetting resin 14.

Title: Output interface circuit
Inventor: MINE HIROTOSHI
IPC: H03K17/567
Filed: 1994-04-21
Abstract: PURPOSE:To obtain a high speed output interface circuit with a small circuit area capable of interfacing directly a semiconductor device in high voltage operation by providing an emitter-base protection circuit to cut a base current which applies a reverse voltage to a transistor(TR). CONSTITUTION:An EB protection circuit 5 has a function of supplying a current to a base of a bipolar TR to control its operation and extracting a charge of the base at the interruption. When destruction of an element takes place due to a breakdown between the base and the emitter, a path for a reverse current in the breakdown state is blocked. That is, when a level at an output terminal TO rises and it is possible that a reverse voltage is applied between the base and the emitter, a level of an EB protection signal EB goes to an L level. Thus, a TRN 51 is cut off and it is prevented that the base of the TRQ11 reaches a level of a power supply SV, that is, a ground potential via a TRN 52. As a result, a cause damage the TRQ 11 is eliminated and the reliability is improved.
