For a support it is preferable to use a transparent plastic substrate, and more preferable are injection-molded polymethyl methacrylate and injection- molded polycarbonate resin substrates which are pre-grooved when injection- molded. Moreover, a 2P pre-grooved resin substrate is especially desirable since it is available at a relatively low price. A compound shown in the formula (I) may be a solution dissolved in a solvent, and such a solvent may be directly applied to a support, i.e. a substrate, or may be used together with a binder. A binder suitable for this purpose is selected from polyester and various types of acrylic resins.

Filed: 1988-09-30
Abstract: PURPOSE:To improve the speed of maintenance processing and to reduce the use capacity of a file by providing an index for maintenance together with a coupling index in a relational data base control system. CONSTITUTION:In the relational data base control system, an index 2 for maintenance is prepared together with a coupling index 1. Thus, the coupling index 1 can be maintained more speedily than a case that the index is not prepared in a coupling subject string. Then, since the coupling index 1 is maintained at a high speed, the use capacity of the file can be reduced much more than a case where the indexes are respectively prepared to the coupling subject strings in two tables to be coupled. Even when special processing is not executed to maintain the coupling index, the coupling index can be maintained.

Abstract: PURPOSE:To eliminate the displacement of positions and the inclination of elements in case of mounting of semiconductor elements, by forming the metal layer of high melting point on both sides of the insulative substrate on which semiconductor elements are mounted, and by selectively forming the metal layer of the melting point lower than 450 deg.C on one side on which the elements are adhered. CONSTITUTION:On both sides of the insulative substrate 200, the metal layer 201 and 202 are formed which are made of high melting point metal like Mo. On either surface of the two layers, the metal layer 204 is selectively formed which is made of low melting point metal such as Au-Si. Without using any wax being apt to deform, the semiconductor element 203 is directly stuck to the metal layer 204 formed on the insulative substrate 200. This process improves operation efficiency and eliminates the defect wherein the semiconductor element inclines and the wax flows out to the connecting part of the thin metal wire 210 of the metal plate 201 on the insulative substrate 200.
