Title: Method for electrolytic fluorination
Inventor: OKADA NAOYA
IPC: C25B3/28
Filed: 1988-05-10
Abstract: PURPOSE:To obtain a completely fluorinated trialkylamine having a large number of carbon atoms in high yield by electrolytically fluorinating a mixture of a trialkylamine having a relatively large number of carbon atoms and a trialkylamine having a relatively small number of carbon atoms. CONSTITUTION:A mixture of a 15-24C trialkylamine and a 3-14C trialkylamine is charged in an electrolytic cell having an anode and a cathode along with hydrogen fluoride, and a current is applied between both electrodes. The electrode is appropriately made of nickel or its alloy. The electrolysis is appropriately performed at about -15-20 deg.C, about 0.1-5A/dm<2> current density, and about 4-9V cell voltage. The content of the trialkylamine having a small number of carbon atoms in the mixture is preferably controlled to about 10-90wt.%, or especially to about 20-70%. As a result, the trialkyamine having a large number of carbon atoms is completely fluorinated, and the fluorinated trialkyamine can be easily separated and recovered in high yield.

Abstract: PROBLEM TO BE SOLVED: To automate an arrangement plan of the contents by monitoring an information storage means and selecting an information storage device which delivers the contents based on the monitoring result of the information storage means. SOLUTION: A monitoring means 110 previously monitors the performance information on the information storage devices 200i (i=1, 2...n) and sends the monitoring results such as the idle capacity, the traffic allowance value, the past failure history information, etc., to a selection means 190.

A contents delivery means 140 loads the contents into the device 200i of the highest priority. At the same time, a correspondence relation recording mesnes 150 keeps the correspondence relation between the contents and the device 200i storing the contents and decides whether the same contents are stored in the single device 200i or not.

IPC: C22F1/04
Filed: 1979-09-05
Abstract: PURPOSE: To enhance vibration damping capability and to maintain high strength by a method wherein an Al-Co based alloy having a specified amount of Co is subjected to a cold working factor.  
     CONSTITUTION: An alloy is formed by melting 0.1W20wt% of Co and the remaining Al, and if required, auxiliary componets including specified amount of Pb, Sb, Ce, Ta, Fe, Nb, Zr, Ti, Ca, and B. The alloy is heated to a temperature from 250°C to its melting point for 5 minutes or more, cooled either rapidly or gradually at a rate of 1°C/sec or less, and is subjected to a cold working with factor of 5% or more. After the process with the 5% more of cold working factor, the  alloy may be heated and cooled. The process provides an Al-Co based vibration absorbing alloy having a damping capacity of 6×10 -3  or more. Because of its high  damping capacity, good cold workability, and nonferromagnetic property, the alloy  is suited as structure material for traffic facilities, internal combustion engines, and  large machines to prevent the vibration and noise or to reduce their weight.

Title: Monolithic microwave integrated circuit
Inventor: MITSUI YASURO
IPC: H01L21/338
Filed: 1987-05-08
Abstract: PURPOSE:To integrate an IC chip, by designing a bias circuit such that a lumped-constant type inductor having a meander shape is constructed integrally with a capacitor provided by a capacity of a depletion layer. CONSTITUTION:Terminals 14 and 15 are arranged between patterns of meander- shaped ohmic electrodes 12 connected to a bias power supply terminal and a microwave circuit section 14, respectively. A Schottky electrode 15 formed of a Schottky metal is opposed to the ohmic electrode 14. Since a positive voltage VDD is applied to the terminal 14, a depletion layer 19 is created between the ohmic electrode 12 and the grounded Schottky electrode 16, which consequently creates a depletion layer capacity corresponding to the distance along which the electrodes are opposed to each other. According to this construction, since an inductor provided by the meander-type electrode is constructed integrally with a capacitor provided by said capacity of the depletion layer, the area of a bias circuit can be decreased.
