Patent JP-S63198351-A (JP)
Title: Adhesion of semiconductor wafer
Inventor: WATASE MANABU
IPC: H01L21/68
Filed: 1987-02-13
Abstract: PURPOSE:To enhance the adhesion accuracy by a method wherein a pressurebonding process to pressure-bond a semiconductor wafer to a substrate via a wax is executed in a vacuum. CONSTITUTION:When a semiconductor wafer 1 is bonded to a substrate 2 by using a wax 3, it is pressure-bonded in a vacuum; accordingly, an air bubble contained in the wax 3 which is situated between the semiconductor wafer 1 and the substrate 2 can be removed. That is to say, when the semiconductor wafer 1 is pressure-bonded to a substrate 2, the inside of a vacuum container 5 is evacuated to produce a vacuum and a pressure-bonding process is then executed. By this method, the air bubble contained in the wax 3 can be removed; even when the semiconductor wafer 1 is made to be a thin film, the adhesiveness of the semiconductor wafer 1 to the substrate 2 is enhanced; it is possible to prevent the bonded assembly from being exfoliated partially or the like; in addition, the yield rate of a device can be enhanced.

Title: Display panel drive method
IPC: G09G3/20
Filed: 1993-02-22
Abstract: PURPOSE:To provide a liquid crystal television receiver with high picture quality by inverting the polarity of an applied electric field in the minimum unit of one horizontal scanning period for a frame period so as to avoid crosstalk. CONSTITUTION:Voltage waveforms VRi-1-VRi+1 of a scanning signal electrode and a voltage waveform Vcj on a picture signal electrode Cj (tL is one horizontal scanning period) in figure indicate that the polarity of the (i-1)th scanning signal is positive by taking a ground potential or a prescribed DC potential as a reference and the polarity of the i-th scanning signal is negative and that the polarity of the scanning signals per one scanning line are being inverted. On the other hand, as to the voltage waveform Vcj on the picture signal electrode Cj in reference to the scanning signal and the picture signal, the polarity of the applied voltage per one scanning signal line is being inverted. Thus, the polarity of the applied voltage in a frame time is being inverted in the minimum unit of one horizontal scanning period in this way.

Title: Three-phase load tap changeover transformer
Inventor: KASAGI HIROYUKI
IPC: H01F29/04
Filed: 1978-03-23
Abstract: PURPOSE: To reduce the magnetic unbalance between high and low main windings by arranging high pressure voltage tap windings between two divided high voltage main windings geometrically or coaxially with these windings.  
     CONSTITUTION: The high voltage tap winding 2 is arranged coaxially with the high voltage main windings and geometrically near the center of the high voltage windings in an arrangement of the first high voltage main winding 1A, high voltage tap winding 2, and the second main winding 1B. Electrically, the U- and W-phases high voltage tap winding 2 is connected to the Z terminal. The V phase is directly connected to the V terminal in the order of U - 1A - X, ... Z4 - 2 - Z. The tap of the two high voltage tap windings located at the same line is switched by a common load tap changeover unit. This permits the magnetic unbalance between the high and low windings to comparatively be reduced and a two phase load tap changeover unit to be shared by one unit. As a whole, the load tap of a three-phase triangular connection is enabled using two load tap changeover units.
