Title: Package for face-down for saw element
Inventor: YATSUDA HIROMI
IPC: H03H9/10
Filed: 1992-05-27
Abstract: PURPOSE:To improve accuracy for matching the position of the electrode of a surface acoustic wave(SAW) element inserted to the package and the position of a pad for electrode at the bottom part of the package. CONSTITUTION:A side wall 16 of a package 10 is provided with linear inner wall surfaces 22a-22d adjacent to outer side surfaces 20a-20d of a SAW element S and recessed parts 26a-26d formed at positions corresponding to corner parts 24a-24d of the SAW element S where the above-mentioned inner wall surfaces 22a-22d are crossed. Since the above-mentioned corner parts 24a-24cl inserted along the above-mentioned inner wall surfaces 22a-22d are not abutted to the recessed parts 26a-26d on the side wall 16, the side wall 16 is produced so that the above-mentioned outer side surfaces 20a-20d are extremely adjacent to the inner wall surfaces 22a-22d of the side wall 16. Therefore, accuracy is improved for positioning an electrode pad 12 of a bottom board 14, input electrode pad 30 of the SAW element S, and output electrode pad 36.

Title: Curvature correcting method of wafer
Inventor: SEGAWA MIKIO
IPC: G11C11/14
Filed: 1984-06-29
Abstract: PURPOSE:To correct curvature due to a difference in coefficient of thermal expansion between a substrate and an adhered body when the wafer is placed at room temperatures, and reduce strain applied to a magnetic garnet film by adhering resin which has a larger coefficient of thermal expansion than the substrate and curing it at high temperatures. CONSTITUTION:The extent of curvature of the wafer is measured at room temperatures and heat-resisting silicone resin 9 is applied by a spinner over the adhered body to a thickness suitable for the correction of the curvature and cured at high temperature. The relation between the curvature extent of the wafer and the film thickness of the heat-resisting silicone resin 9 required for the correction is found previously by experiment, and the film thickness of the silicone resin 9 is controlled by varying the rotating speed of the spinner. The coefficient of thermal expansion of the heat-resisting silicone resin is larger than that of the substrate and when a film is formed to about 0.5mum, the curvature of the wafer is returned to its original state.

Title: Resist ink for electroless plating
Inventor: UOZU NOBUO
IPC: C09D11/102
Filed: 1983-07-25
Abstract: PURPOSE:To provide resist ink for electroless plating which prevent copper release and has high reliability by consisting the name of an epoxy resin compsn. contg. a filler mixed with aluminum silicate having a prescribed grain size or below, a solid soln. of titanium oxide, nickel oxide and antimony oxide and ultrafine grain silica. CONSTITUTION:This resist ink is constituted of an epoxy resin compn. contg. a filler mixed with aluminum silicate having <=15mu grain size, a solid soln. of the above-described oxides and fine grain silica. More specification, the manufacture of a printed wiring board is accomplished by coating an adhesive agent contg. a platng catalyst such as Pd on a base plate such as a paper-phenolic resin laminate contg. a plating catalyst such as Pd then printing the above- described ink for resist thereon. Since the ink for resist has extremely fine particles, the ruggedness on the printed surface is small. Therefore if the surface is thereafter subjected to an electroless plating treatment, copper is hardly stickable to the surface of the resist ink and particularly the solid soln. and the ultrafine grain silica have the effect of making difficult the growth of copper particles sticking to the surface. The generation of copper release and the short circuiting defect occurring therefrom are thus suppressed.

Title: Manufacture of rolled plate of composite material of short fiber or particle dispersion reinforced metal base
Inventor: KOBAYASHI YASUO
IPC: B21B1/38
Filed: 1990-05-25
Abstract: PURPOSE:To obtain a good rolled plate without surface checking by sandwiching both surfaces of a base metal for plate which consists of a composite material with the plates of a metal or alloy with extensibility, constituting a laminated body by interposing lubricant between this base metal and the above-mentioned metal or alloy plate, heating and rolling. CONSTITUTION:When the base metal for plate which consists of short fibers or partile dispersion composite material is rolled with a roll, it is sandwiched with metallic alloy plates with extensibility. The direct contact of the composite material with rolling rolls is prevented, the temp. drop of the composite material due to dissipating heat with the rolls is restrained and tensile stress that is generated in the vicinity of the contact surface of roll isn't exerted on the composite material. By the use of lubricant, the stick between the composite material and the extensive metal or alloy plate due to rolling is prevented and, when the composite material is extended by rolling, the rolling of the metal or alloy plate is restrained at a minimum and slip between the composite material and the metal or alloy plate that is caused during that time is facilitated. In this way, productivity is improved and internal defects can be reduced by making the planar composite material into a extending worked meteriel.

Title: Decision feedback type equalizer
Inventor: TSUJIMOTO ICHIRO
IPC: H03H21/00
Filed: 1990-05-25
Abstract: PURPOSE:To ensure initial pull-in of an equalizer by decreasing a tap coefficient of a backward equalizer more than that in the normal operation in response to the decrease in an output signal level of a forward equalizer. CONSTITUTION:When a backward equalizer is divergent, the output of a forward equalizer FE1 goes to zero, a detector 6 detects the reduction in the level and sends the information to a tap correction coefficient controller 7. When the BE 2 is divergent, a square mean value xsi of an error signal epsilon exceeds a threshold level gammax of erroneous decision. The controller 7 prepare control threshold levels gamma1, gamma2 with respect to the square mean value xsi of the error signal epsilon of a decision device 3 to monitor to which range of the threshold levels the square mean value xsi belongs. When a loop comprising the BE 2 and the device 3 is opened, the controller 7 sets a tap correction coefficient nu to a smaller value nu1. When the square mean value xsi is lower than the value gamma1, the controller 7 sets the coefficient nu to a coefficient nu2 a little larger than the value nu1. As a result, multi-path distortion is tightly subject to adaptive equalization.
