IPC: H01L39/24
Filed: 1992-08-04
Abstract: PURPOSE:To form a step having a desired shape at an arbitrary position on a substrate by a simple method. CONSTITUTION:In the method, a superconducting thin film 5 is formed on a substrate 1 on which a step having a level difference equal to the thickness of a sputtered film 3 is formed in such a way that the film 3 is formed on the surface of a substrate 1 by sputtering the same material as that of the substrate 1 at a low temperature at which a photoresist is not damaged after a pattern is formed on the substrate 1 by using the resist 2 and removing the photoresist 2. Since the stepped substrate is manufactured and the superconducting thin film is formed on the substrate by combining the lift-off method and low-temperature sputtering method in such a way, the manufacturing method is extremely simple and, in addition, any step having a desire shape can be easily formed at an arbitrary position on the surface of the substrate with accuracy.

Title: Hetero-junction bipolar-transistor formed onto critical non-orientation substrate
Inventor: REIMONDO KEI TSUI
IPC: H01L29/737
Filed: 1989-08-14
Abstract: PURPOSE: To provide a heterojunction bipolar transistor sharply decreasing or removing a collector/emitter offset voltage by constituting this transistor of a semiconductor emitter layer, a semiconductor collector layer, which are arranged on a critical non-oriented semiconductor wafer, and a semiconductor base layer positioned between these layers. CONSTITUTION: A semiconductor wafer 12 is shifted critically or non-oriented and non-oriented from a face <100> to a gallium face <111>.

Title: Material for building
Inventor: NAKAMURA SHOZO
IPC: B27M3/08
Filed: 1987-08-20
Abstract: PURPOSE: To increase mechanical strength of joined portions by dividing lumber for circular pillar in sections lengthwise to form sectroal components and by tightly adhering them in the shape of cross section. CONSTITUTION: Lumber 3 for construction is formed in a long shape with cross section before the cut by cutting circular pillared lumber 2 lengthwise with orthogonal planes a1 and a2 crossing the center axis into four sectoral components 11 -14 with the same cross section, shifting each of them so that end faces 41 , 42 , 43 and 44 do not come to the same cross section, adhering each of bonding faces 51 , 52 , 53 and 54 with glue and thick rod 6 with appropriate spacing, and sticking each of bonded faces 41 , 42 , 43 and 44 with glue. This causes faster and uniform desiccation with natural drying, so that large bending or distortion does not often take place. Because mechanical strength at joined portions has been reinforced, long lumber with a high mechanical strength for construction can be produced by using short lumber for circular pillars.  Lumber for construction 3 is used as material for beam, girder, pillar, foundation and the like.

Title: Method and flowmeter for measuring flow rate of fluid of pulsation flow
Inventor: YOHANESU HAATOFUIIRU
IPC: G01F1/24
Filed: 1991-08-20
Abstract: PURPOSE: To measure the flow rate of a fluid having a strong pulsation flow by using a float which is energized with a restoring force in the direction opposite to the flowing direction of the fluid so that the float can move in a pipe to be measured and always measuring the speed of the float. CONSTITUTION: A float 2 can freely move in a pipe 1 to be measured and the attracting force of the earth acts on the float 2 as a restoring force, because the pipe 1 stands upright. A fluid flows upward in the pipe 1 in the opposite direction to the gravity. Since the diameter of the float 2 is smaller than the inside diameter of the pipe 1, an annular space 8 is formed between the pipe 1 and the float 2 and the fluid can flow through the space 8. Because of the constricting effect and the flowing force generated at the space 8, a pressure difference occurs between both sides of the float 2 and the float 2 moves in the direction shown by the arrow together with the fluid.  Since the movement of the float 2 becomes faster as the speed of the fluid increases, the flow rate of the fluid can be decided from the velocity gradient of the fluid by finding the flow velocity of the fluid from the speed of the float 2.

Abstract: PROBLEM TO BE SOLVED: To obtain the excellent adhesive strength of a conductor layer to an insulating layer and the reliability of the connection of a via hole by a method wherein the surface of the precedently formed conductor layer of an internal layer circuit is roughened and the surface of a part, which is electrically connected with the following conductor layer via the via hole, of the precedently formed conductor layer is formed into a glossy surface by a smoothing treatment. SOLUTION: First, if the surface of a conductor layer 1 is roughened 3, an anchoring effect is generated. As a result, as the adhesiveness of the layer 1 to a heat-resistant resin insulating layer 4, which is formed on the upper part of the layer 1, is improved, a crack, which is generated at the time of a laser processing or the like, can be prevented from being generated in the layer 1. However, on one hand, as seen a part, which is electrically connected with the following conductor layer 7 which is formed after the formation of the layer 1 through a via hole, of the layer 1 in the relation between the layer 1 and the layer 7, the connection performance of the part is electrically deteriorated.  Thereby, by performing a smoothing treatment 6 on at least one part of this part, the connection surface, which has the shape changed by a roughening treatment, of the layer 1 with the layer 7 and the surface, which is generated a chemical change, of the layer 1 are removed. As a result, if the layer 7 is electrically connected with the smooth surface of the layer 1, a reduction in the reliability of the connection of the via hole can be prevented from being generated.
