Title: Feedforward control system
Inventor: SASAKI TAKAO
IPC: G05B11/32
Filed: 1989-04-18
Abstract: PURPOSE:To accurately execute the interpolation outputting of a numerical control part and to execute feedforward control by the interpolation output by providing the feedforward control system with an interpolator for outputting the an interpolation output less than an interpolation pulse unit, a feedforward control element for forming a feedforward item, an integer forming circuit, and a servo circuit. CONSTITUTION:An interpolation output including a decimal of the interpolator 11 is added to the output of the feedforward control element 12 by an adder 13. Namely, the output of the adder 13 indicates the value obtained by adding a feedforward item to the interpolation output of the interpolator 11, and since the output includes a decimal point, the output is converted into an integer pulse in each interpolation by the integerinzing circuit 14 and the integer pulse is sent to the servo circuit 20. Namely, an accurate feedforward item can be found out by the element 12 arranged in a numerical control part 10 by using the interpolation output of the interpolator including a decimal less than the output pulse unit. Consequently, accurate feedforward control can be attained.

Title: Manufacture of alloy brazing material for semiconductor device assembly use
Inventor: MINAMI HIRONAO
IPC: B23K35/14
Filed: 1989-04-20
Abstract: PURPOSE:To effectively restrain a void from being produced by a method wherein an alloy, for brazing material use, which has been plastic-processed to a specific size shape is heated, melted and solidified in an atmosphere of hydrogen. CONSTITUTION:An ingot of an alloy, for brazing material use, obtained by a melting operation and a casting operation is plastic-processed by an extrusion operation, a rolling operation, a stamping operation or the like. A circular sheet whose thickness is 0.004mm or higher and whose diameter is 0.2mm or higher, or a square or rectangular sheet whose thickness is 0.004mm or higher and whose length for one side is 0.5mm or higher is formed. Since a plastic-processing oil remains on the surface after this processing, the oil is removed. The alloy, for brazing material use, which has been processed to be sheetlike is heated up to a melting point or higher of the alloy inside a furnace whose hydrogen atmosphere has been kept; it is melted. After that, the alloy is cooled as it is and solidified. While the alloy, for brazing material use, processed to be sheetlike is being melted, a reducing reaction by hydrogen acts. When it is solidified, an oxide is reduced. Thereby, it is possible to obtain an alloy brazing material in which few voids are produced when it is used to braze an Si chip or the like to a board.

Filed: 1987-04-22
Abstract: PURPOSE:To obtain a ferroelectric liquid crystal panel which hardly forms twist structure and has a strong memory characteristic and good display grade by using overcoating layers which are different with upper and lower substrates to prepare the ferroelectric liquid crystal panel. CONSTITUTION:The liquid crystal layer 6 is a ferroelectric liquid crystal and insulating layers provided on electrodes are of the materials different between the upper and lower opposed substrates. For example, silicon monoxide is used for one substrate as the material to be used for the overcoating layer and yttrium oxide is used for another substrate and the different over coating layers 4, 7 are provided on the upper and lower substrates 2 by executing vapor deposition. A difference in the polarities on the surfaces of the upper and lower substrates 2 is generated by using such layers, by which a difference is provided in the spontaneous polarization of the ferroelectric liquid crystal molecules and the polarities on the surfaces of the substrates 2. The directions of the spontaneous polarization with respect to the substrates 2 are thereby reverse on the upper and lower surfaces, by which the appearance of the twist state is suppressed and the ferroelectric liquid crystal panel having a strong memory effect is realized.
