Title: Multilayered printed wiring board
Inventor: TAKADA KOSUKE
IPC: H05K3/46
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of such an abnormality as a crack and a measling due to a thermal shock even if an internal layer circuit board has a conductor layer in an internal thick layer, and to contrive the enhancement of the reliability of the printed wiring board, by a method wherein the hot extensibility of the conductor layer in the printed wiring board is specified. SOLUTION: In a multilayered printed wiring board of a structure, wherein a constituent material comprises an internal layer circuit board having a conductor layer of a thickness of 60 μm or thicker and the glass transition point of a matrix resin is 15 deg.C or higher, the hot extensibility of the conductor layer of the thickness of 60 μm or thicker at 180 deg.C is assumed 10% or higher. Here, the hot extensibility of a copper foil, which is used for a general copper-clad laminated board, at 180 deg.C is 15% or lower. Owing to this, when a heat shock is given to the printed wiring board, the printed wiring board can nor follow the abrupt thermal expansion and contraction of an insulation adhesion layer, a stress is given to the adhesion layer and a crack and a measling are developed in the adhesion layer.  When the hot extensibility of the conductor layer at 180 deg.C is assumed 10% or higher, the printed wiring board follows the thermal expansion and contraction of the adhesion layer to expand and contract. Owing to this, as the stress is not given to the adhesion layer, the developing of the crack and the like in the adhesion layer is prevented.

IPC: H03H17/02
Filed: 1993-04-08

Title: Detector for electromagnetic flowmeter
Inventor: ISHIDA YOSHIZO
IPC: G01F1/58
Filed: 1990-03-29
Abstract: PURPOSE:To make it possible to measure a flow rate with few errors by providing a means for decreasing the distribution of the magnetic flux density in the vicinity of electrodes so that generated electromotive force is hard to be affected by the flow-speed distribution. CONSTITUTION:U-shaped magnetic cores 6a and 6b are arranged in the vicinity of electrodes 2a and 2b of a detector and at the outside of a measuring pipe 1. Then, parts of magnetic fluxs generated from exciting coils 3a and 3b which pass through the vicinity of the electrodes 2a and 2b are converged and guided in the directions of the magnetic cores 6a and 6b as shown by arrows in the figure. The magnetic flux passing through the inside of the measuring pipe in the vicinity of the electrodes 2a and 2b becomes less. Therefore, the value of magnetic flux X weighting function does not become so large. The distribution of the values of magnetic flux density X weighting function in the pipe approaches the uniform state in the cross section of the pipe including the electrodes. The generated electromotive force becomes hard to be affected by the flow-speed distribution, and the measurement with less errors can be performed.

Title: Method of semiconductor wafer and semiconductor wafer using the method
Inventor: KOBAYASHI MAKOTO
IPC: H01L21/302
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To solve the prolongation of a wafer process time and unstability depending on the shape of a starting wafer to improve the productivity of a high-flatness semiconductor wafer, by making the wafer concave before the vapor phase etching. SOLUTION: Before the vapor phase etching, a wafer is concave, i.e., in a primary polish step of polishing the wafer, it is done by raising the polishing pressure at a central part of the wafer. This polishing applies to both surfaces of the wafer to remove undulation components of 1-50 mm in wavelength on the front and back surfaces of the wafer, thereby concaving the wafer, and then the vapor phase etching of the wafer is made. If the surface roughness of the wafer is reduced before the vapor phase etching, the quantity of parts to be removed from the wafer by the vapor phase etching can be reduced and the wafer can be planarized for a short time.

IPC: H02J3/00
Filed: 1988-04-04
Abstract: PURPOSE:To restrict the maximum demand power of a DC substation to a contract power or less by operating the control angle of a rectifier in response to an input power amount to a plurality of DC substations for supplying powers to electric railways. CONSTITUTION:Input power amount calculating means 22 calculates a variable W1 from a momentary power P by a formula I, while input power amount calculating means 23 calculates a variable W2 by a formula II, a power amount reference unit 26 sets a reference value WP meeting contract power, and they are applied to a logic circuit 24. The circuit 24 calculates the value PP of the input power of a thyristor recitifier 17 by a formula III, and outputs it to a calculator 27. When it tends to become W1>=WP or W2<=WP, the output voltage of the rectifier 17 is reduced by a reference value PP-P to regulate the power of its own substation. On the other hand, in case of W1<WP and W2<WP, the control angle of the rectifier 17 is set to '0 deg.', i.e., the control rate is set to '1', and the power factor of the power source is set to '1'.
