Title: Vibration control method of building
Inventor: KATO MITSUHARU
IPC: E04H9/02
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To control vibration by oppositely inclining two steel members in a secondary wall erected in a building and installing them to form an X-shape in a front view and fixing the upper and lower ends thereof in the upper and lower beam bodies. SOLUTION: A pair of steel members 4, 5 which are prevented from sticking to concrete by applying grease or the like are oppositely tilted to form an X-shape in a front view and embedded in a concrete secondary wall 3 disposed between column bodies 1 of respective floors. The upper and lower ends of the steel members 4, 5 are fixed to connection plates 6 arranged in beams 2 to connect the steel members 4, 5 of respective floors. When it is required, a narrow gap 7 is formed between respective upper and lower end faces of the beam 2 and the wall 3 to prevent occurrence of an axial force or a shear force. Further, the section of a part of the steel members 4, 5 are notched to early actuate a tensile yield or a compressive yield. When a building vibrates in an earth quake or the like, a tensile force or a compressive force acts on one of steel members 4, 5 and hence, the steel members 4, 5 yield with tension or compression and energy is absorbed by the restoring force characteristic to control the vibration. In this way, the vibration of a building can be controlled by a simple structure without impairing the external appearance.

Title: Semiconductor device
Inventor: MOROSHIMA HEIJI
IPC: H01L29/872
Filed: 1980-08-20
Abstract: PURPOSE:To obtain a highly reliable Schottky barrier diode by increasing the impurity concentration of an Si layer gradually or by stages thicknesswise. CONSTITUTION:First, an N type first epitaxial layer 2 is laid on an N<+> type substrate 1 doped with Sb and subsequently, an N type second epitaxial layer is thereon at a relatively low concentration. A metal 4 such as Al is piled thereon. The concentration of the epitaxial layer is varied gradually with the growth temperature and conditions of the subsequent heat treatment. First and second epitaxial layers both doped with an impurity hard to diffuse by heat are laid on the substrate one upon another and finally, a low temperature epitaxial layer is laid thereon so that the concentration may be changed by stages. With such an arrangement, a sharp concentration gradient is eliminated between the layers. This relaxes the capacitive action of the epitaxial layers, namely, inductive action between the metal layer and the substrate thereby removing the concentration of the electric field during the operation. Accordingly, the electrostatic breakdown strength can be increased sufficiently thereby providing a highly reliable Schottky barrier diode.

Title: Etching-processing method for silicon nitride film, and its device
Inventor: KOBAYASHI SHUNICHI
IPC: H01L21/302
Filed: 1990-04-27
Abstract: PURPOSE:To prevent plasma damage and to increase the selection ratio in a silicon oxide film and a silicon nitride film by etching-processing the silicon nitride film using a halogen fluoride gas expressed by a rational formula FX when a halogen element other than fluorine (F) is expressed by X. CONSTITUTION:ClF3, ClF, and BrF3 are especially effective for halogen fluoride gases. ClF3 and Ar are supplied to the inside of a silica chamber 1 from an etching gas supplying means 3, the pressure inside the silica chamber 1 is reduced by a vacuum pump 4, and this etching gas is caused to flow inside the silica chamber 1 bringing it in the state of gas through. As a halogen fluoride gas expressed by a rational formula FX (where X expresses a halogen element other than fluorine (F)) decomposes and discharges fluorine as a radical, this reacts with silicon nitride, produces a volatile substance, and etches a silicon nitride film from the surface. At this time, the halogen fluoride gas decomposes easily even in a plasmaless atmosphere, discharges radicals of fluorine being etching seeds, and reacts with the silicon nitride film chemically. Accordingly, plasma damage of semiconductor devices can be prevented.
