Filed: 1989-05-19
Abstract: PURPOSE:To obtain die bonding having high reliability without damaging electric conductivity by growing a high melting-point metallic thin-film onto a gold metallic film on the rear of a chip bonded with a package through die bonding. CONSTITUTION:A gold thin-film 12 is grown onto a rear, on which the element of a semiconductor substrate 11 is not formed, in a vacuum chamber, and a high melting-point thin film 13 is grown continuously onto the gold thin-film 12 in the vacuum chamber. A chip 11 cut out of the semiconductor substrate 11 is bonded with a package under the state in which the high melting-point thin-film 13 side is welded to a gold thin-film 15 on the package 14. Even when Si is diffused onto the surface of the metallic thin-film 12 in a process in which the chip 11 is thermally welded to the package 14, the oxidation of the thin-film 12 is prevented because the surface of the metallic thin-film 12 is covered with the high melting-point thin-film 13. Accordingly, die bonding can be conducted without oxidizing Si being diffused onto the surface of the metallic film 12 while keeping excellent electric conductivity.

Filed: 1990-05-16
Abstract: PURPOSE:To shorten the working time and thereby improve the production efficiency by providing a constitution in which the width of a bag can be changed rapidly and accurately without interruption of transporting a bag material. CONSTITUTION:A bent part 5 is provided with a pair of molding roller parts 10 which creases a bag material 2 and a roller support shaft 11. A pair of top guides 17 are formed on the top of a support table 21 fixed to a frame so that a space surrounded by the paired top guides 17 becomes narrow gradually. On the lower surface of the space, a side guide 19 is fixed and a guide support shaft 20 is introduced through the side guide 19. The bag material is pressed against the support table 2 by a roller 12 of the molding roller part 10 and transported with a crease 2a formed. In this case, the both lateral ends are restricted by the side guide 19 and the width of the bag is determined by folding back the bag material. Further, the folded back upper part is folded back long under the restriction by the top guide 17, and then is sent to a next process with the stacked folded parts. If the width of the bag is increased, the roller support shaft 11 is rotated to move the roller 12 outwardly. At the same time, a guide support shaft 20 is rotated to allow a top guide 17 and the side guide 9 to move outwardly.

Abstract: PURPOSE:To obtain a stable picture, by using a charge transfer part itself as a buffer memory to refresh partially a picture signal repeatedly. CONSTITUTION:A photoelectric charge corresponding to the photographed picture of each picture element is stored in the photo detecting part of a solid-state image pickup element 20. In recording to a recording device 21, the picture signal is circulated in a transfer register of the solid-state image pickup element 20 because terminals 5 and 8 are connected. The frequency of driving pulses is brought into the monitor (television) band to output one-screen components of the picture signal repeatedly to a terminal 22, and one-screen components of still picture are reproduced successively on the monitor device. A part of one screen, namely, one-line components of the picture signal are read out to a register 23 from the storage device 21, and new one-line components of the picture signal are transferred from the register 23 to the register in the solid-state image pickup element 20 synchronously with this readout, and thus, the picture signal is refreshed.

Title: Exhaust emission control device
Inventor: KUMAGAI SHIRO
IPC: F01N13/02
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To quickly recover the emission control capacity of an NOx-occluding reduction catalyst incorporated into an exhaust emission control device together with an upstream three-way catalyst. SOLUTION: An NOx-occluding reduction catalyst carries Ni as a catalyzer on its alumina-carrying layer. When the engine is operated in a rich air-fuel ratio range, a reducing atmosphere is produced about the NOx catalyst, which atmosphere triggers a reaction of converting NiO into NiS with consumption of H2 S. Such consumption in turn promotes consumption of SO2 and a reaction of converting BaSO4 or a sulfur oxide depositing on the NOx catalyst into BaCO3 or an NOx occluding agent in an oxidizing atmosphere thereby recovering the emission control capacity of the NOx catalyst.

Abstract: PURPOSE:To make a controller of smaller size by constituting its input section with a manual switch and its output section with an anolyte pump, and varying the operating voltage of the anolyte pump in accordance to the judgment of a microcomputer to determine ON or OFF status of the manual switch. CONSTITUTION:An anolyte pump 2 runs on DC power, and signals from an 8V operation switch 3 and a 10V operation switch 4 are fed to a microcomputer 1 which uses these signals to determine the operating voltage of the anolyte pump 2 and delivers 4-bit or 8-bit digital signals. A DA converter 7 converts these digital signals to analogue signals which serve as the operating voltage of the anolyte pump 2. When the 8V operation switch 3 and the 10V operation switch 4 are OFF, the anolyte pump runs on 6V power. When the 8V operation switch 3 is ON, the pump 2 runs on 8V power and, when the 8V operation switch 3 is OFF and the 10V operation switch 4 is ON, the pump 2 runs on 10V power. By this constitution, a compact controller of liquid fuel cell can be made.
