Abstract: PURPOSE:To provide a printed wiring board excellent in copper migration even if high voltage is applied, by having a substance, where specified pts.wt. of nitrile rubber being refined to contain only specified ppm or less impurity ions is mixed to specified pts.wt. of epoxy resin, for its main ingredient. CONSTITUTION:This printed wiring board has a substance, where 10-70 pts.wt. of nitryl rubber being refined to contain only 1000ppm or, less impurity ions is mixed to 100 pts.wt. of epoxy resin, for its main ingredient. As epoxy resin, bisphenol A type of diglycydil ether or the like is used. As nitrile rubber, ternary copolymer rubber such as acrylonitrile or the like is used. And, it is suitable to mix a hardener further to the mixture of epoxy resin and nitryl rubber. For example, a variety of phenylene diamine can be cited. Hereby, copper migration little occurs even under the severe condition where high voltage is applied under high temperature and high moisture, and high reliability can be gotten.

Abstract: PURPOSE: To mold a mold at high efficiency with reduced consumption of shell sand and facility cost, by charging casting sand on the outer surface of shell sand deposited and hardened thinly on a metal mold with the aid of adhesive, and gluing and joining the two mold halves obtained by hardening.  
     CONSTITUTION: In process (d), shell sand 2 is thinly deposited and hardened on the surface of a metal mold 1, and adhesive such as water glass of 50% aqueous solution or phenol resin powder is sprinkled over the outer surface of this sand layer. Self-curing or gas-curing mold sand 4 such as CO 2  mold sand and linocure sand is charged in this adhesive and pressed tight. In process (g), this layer of sand 4 is cured by blowing of gas or heating or letting stand. In the next process (h), the mold is parted, and obtained two mold halves are glued together in process (i) by using adhesive to complete one mold. A multiplicity of molds thus fabricated in the processes above are joined together in process (j) and set up parallel to finish preparation for casting. After casting, the mold is broken, and the product is drawn out, and the mold sand is re-used by adjusting the grain size.

Title: Combustion flask
Inventor: NAGASAWA HIROYUKI
IPC: B01L3/08
Filed: 1992-01-31
Abstract: PURPOSE:To enable the quantification of infinitesimal chloride included in sample carbonate, for example by improving a combustion flask. CONSTITUTION:A combustion flask is used for a combustion flask method in which a sample is burned in a flask 4 for infinitesimal analysis. In the flask 4, a platinum basket 2 is placed. This platinum basket 2 supports the sample and at the same time, it is heated by direct current supplied through a pair of platinum wires 1 by way of lead wires introduced from the outside and used as a heater. By putting a sample directly on the platinum basket 2 to burn, a filter paper for ignition becomes unnecessary. As a little amount of chloride included in the filter paper can thus be excluded, in advance, infinitesimal chloride quantification about a few ppm becomes possible.

Abstract: PURPOSE:To prevent electrode peeling even when a stress is applied to the electronic component by improving a bonding strength between a laminated body and an external electrode composing the electronic component in the chip electronic component mounted on a board. CONSTITUTION:Before an external electrode is provided to a laminated body 21, a laser beam A irradiates for a prescribed time on an optional point of a face on an external electrode 28 in continuity with an internal electrode 25 to form a hole 27. The processing above is repeated while the irradiating position is changed to form lots of holes 27. Similarly, holes are formed by the laser beam A even to other end face on which an external electrode 29 is formed in continuity with the internal electrode 26. Moreover, even when a laser beam A strikes on the part of the laminator other than that on which the external electrode is formed, it gives no trouble when no effect is caused in the characteristic of the electronic component. Then the external electrodes 28, 29 are formed on the face subject to laser treatment by a proper means such as baking, vapor-deposition, sputtering or plating.

Abstract: PURPOSE:To elevate the stopping accuracy, by providing a stopping means for a driving member to be controlled by a detection means to stop the action of the driving member when the passage of any of materials to be detected is detected by the detection means. CONSTITUTION:In a detection mechanism, a top board section 3 slides vertically when a chain 7 is driven with sprocket 12 and at the same time, materials 17 to be detected move together with the chain 7.

Title: Eddy current compensator of power source for electromagnet
Inventor: ISHIDA KOICHI
IPC: H01F7/18
Filed: 1990-02-23
Abstract: PURPOSE:To accurately compensate the loss of the magnetic field produced eddy current by an electromagnet due to eddy current by simulatively calculating the reduction of the magnetic field intensity due to eddy current from a current command value or current detection value, adding the result to a magnetic field intensity command value to generate a simulated value of a new current command value or magnetic field intensity actual value, and subtracting it to correct the parameter of a simulator. CONSTITUTION:A current command value IL* or a current detection value IL is input to a circuit 20 for simulating the eddy current loss, which outputs a magnetic field intensity phi0 corresponding to the eddy current loss, which is added to a magnetic field intensity command value phi* to obtain a new current command value IL* or simulated value phi of a magnetic field intensity actual value. Further, the output of the circuit 20 is added to the value phi*during the operation of the electromagnet. And it is switched to a subtracter 23 to obtain a response of a magnetic field intensity for a noncompensating current command value IL*. Accordingly, correction of the parameter of a transfer function of the circuit 20 is easily executed without regulating a parameter regarding the current response of a main circuit. Thus, the reduction phi0 of a magnetic field intensity due to actual eddy current is cancelled to be accurately compensated.
