Filed: 1993-08-31
Abstract: PURPOSE:To provide a method for producing a coated polyester web excellent in an effect for preventing the staining migration of a disperse dyestuff contained in base fabric into the coating layer of a polyurethane resin or a polyamino acid urethane resin. CONSTITUTION:A method for producing a coated polyester web comprises coating a coating resin solution of polyurethane resin or polyamino acid urethane resin containing an electron beam cross-linkable monomer on a polyester fiber web dyed with a disperse dyestuff, and subsequently irradiating the coating film with electron beams in an atmosphere having an oxygen concentration of <=500ppm. Thus, the coated polyester web excellent in the performance for preventing the staining migration of the disperse dyestuff into the coating film can be produced without using a melamine derivative causing the hardening of the touch and without requiring a treatment under high vacuum by using the general polyurethane resin or polyamino acid urethane resin for the coating film.

Title: Method for regulating content of trace metal in alloy
Inventor: DEGAWA TORU
IPC: C22C1/06
Filed: 1985-10-28
Abstract: PURPOSE:To reduce the amounts of Si, Zr, Ti and Al present in a molten alloy by very small amounts by adding S to the molten alloy in a vessel lined with a calceous refractory material in vacuum. CONSTITUTION:Sulfur or a sulfur compound is added to a molten alloy in a vessel line with a calceous refractory material in vacuum or a nonoxidizing atmosphere and the molten alloy is well agitated. CaO or CaO enriched dolomite may be used as the calceous refractory material. In case of a molten Ni-Cr alloy, Cr2S3 or NiS is preferably added as sulfur or a sulfur compound. The amount of S added is made slightly larger than the difference between the total amount of elements to be removed and that of O and S in the molten alloy with respect to stoichiometric equiv. Thus, the amount of one or more among Si, Ar, Ti and Al in the molten alloy can easily be reduced to the desired value.

Title: Reflection type switch
Inventor: KAWANO HAJIME
IPC: H03K17/687
Filed: 1992-09-10
Abstract: PURPOSE:To increase the maximum cut-off amount of a switch by decreasing the resultant impedance while resonating the inductance of a via hole provided on a semiconductor substrate with a capacitor in the operating frequency. CONSTITUTION:When a pinch off voltage is applied to a gate voltage application terminal 7 of an FET 3, looking from a high frequency signal passing a main line 2, the FET 3 corresponds to an open terminal and the switch becomes a passing state without influencing the passing high frequency. Then, when the voltage is applied to a terminal 7 to gain the same electric potential as a drain, the FET 3 corresponds to a ground terminal to be grounded through the resistance of the FET 3, a capacitor 12, and the inductor of the via hole, looking from the high frequency signal passing the line 2. In the connection section of the line 2 and the FET 3, the high frequency signal is reflected and the switch is in a turned off state. In this case, the higher cut-off amount can be obtained by eliminating the influence of the inductor component of the via hole.
