  • Publication number: 20160318761
    Abstract: A hydrogen production method and hydrogen production system using the reaction of water and aluminum, the hydrogen production method and system being capable of continuously generating hydrogen for a long period of time without causing a decrease in the total amount of hydrogen generation. A hydrogen generation system according to one embodiment of the present invention includes aluminum sheet placed in a container and calcium hydroxide contained in the same container. In the hydrogen production system having the previously described configuration, water is poured in the container to dissolve the calcium hydroxide so that an aqueous solution is prepared, and the aluminum sheet is immersed in this aqueous solution. As a result, the hydrogen generation reaction begins, generating hydrogen gas. The amount, rate and duration of the generation of hydrogen gas can be controlled by adjusting the area and thickness of the aluminum sheet.

  • Patent number: 7006879
    Abstract: In a separate process from a boring process, the prealignment is performed beforehand on the circuit board, employing an alignment device, to create the positional data indicating the position of boring the hole in a pattern within the circuit board. In the boring process, the circuit board is carried into the working apparatus. The panel alignment is made on the circuit board. The positional data for positioning the circuit board on a table of the working apparatus is created. The synthesis of the positional data created by the prealignment and the positional data created by the panel alignment is performed to calculate the boring position of the circuit board on the table. The hole is bored at the calculated position in the circuit board, employing a boring machine of the working apparatus. Thereafter, the circuit board is carried out from the working apparatus.

  • Publication number: 20050260391
    Abstract: A wired circuit board on which a highly reliable conductor pattern is formed, to allow an electronic component to be mounted on it with improved accuracy. An insulating layer 3 is formed on a metal supporting layer 2 having a degree of surface brilliancy of 150-500% in such a manner as to have a haze value of 20-50% and also a conductor pattern 4 is formed on the insulating layer 3, thereby producing a TAB tape carrier 1. In this TAB tape carrier 1, since the metal supporting layer 2 has a specified degree of surface brilliancy of 500% or less, the pattern design of the conductor pattern 4 is optically examined to determine whether it is good or bad with high accuracy.

  • Publication number: 20030219608
    Abstract: A metal transfer sheet which is so low in peel-strength as to be transferred to an object to be transferred with ease and reliability; a producing method thereof; and a ceramic condenser producing method for producing a reliable, compact, thin-layer ceramic condenser with improved production efficiency by transferring a metal layer to the ceramic condenser by using the metal transfer sheet. After a first metal layer is formed on a carrier film in a sputtering or an electrolytic plating method, the member thus formed is dipped in plating solution and voltage is applied in such a way that the first metal layer side is anode, to form a passive film. Sequentially, with the polarity reversed, voltage is applied in such a way that the passive film side is cathode, to form the second metal layer. After this manner, a metal transfer sheet in which the first metal layer and the second metal layer are laminated through the passive film interposed therebetween is obtained.

  • Patent number: 6642478
    Abstract: An ultraviolet beam with high energy density is applied for forming an opening in an electric conductor layer 1 in a flexible wiring board whereas an ultraviolet beam with low energy density is applied for forming an opening in an electrically insulating layer 2 in the flexible wiring board. As a result, excessive heat energy applied for forming a via hole can be reduced, so that the problems can be reduced. In this manner, high quality of the via hole and delicate and accurate processability due to use of the ultraviolet laser beam can be combined to achieve formation of fine patterns densely in the flexible wiring board.
