Title: Method for purification of adenine
Inventor: BUIRUHERUMU KUBUITSUTOMAN
IPC: C07F7/10
Filed: 1990-07-30
Abstract: PURPOSE: To enhance purity of adenine as a starting material for manufacturing pharmaceuticals, without a risk of corrosion in shorter steps, by converting a crude adenine containing by-products with a silylating agent into a bis(trimethylsilyl) derivative and distilling the silylated product directly.  
     CONSTITUTION: A starting crude adenine containing 9-phenyladenine and other by-products is first converted into the N,N'-bis(trimethylsilyl) derivative of the formula with a known silylating agent using preferably a catalyst such as polyphosphoric acid or polyphosphoric acid trimethylsilyl ester. Then, the product in this form is distilled without isolation and the trimethylsilyl group is removed by solvolysis to give a highly purified subject compound. The distillation is effected preferably by preheating at round a melting point of the adenine and then under reduced pressure, using Vigreux column or a packed column. The solvolysis is carried out preferably by use of hot water.

Filed: 1988-08-17
Abstract: PURPOSE:To retain good resistance characteristic stably for a long time by covering the surface of a field relaxation layer with a moisture-proof protective layer for setting moisture-resisting resin to be a main agent. CONSTITUTION:On the surface of the main insulation layer 2 of a stator coil 10, the corona shield layer 3 of low resistance and a field relaxation layer 4 are formed. besides, a moisture-proof protective layer 5 crossing the low resistance corona shield layer 3 and main insulation layer 2 on both the sides of the field relaxation layer 4, to cover the layer 4 is set. For the moisture-proof protective layer 5, the synthetic resin paint of the epoxy resin of high moisture resistance (low moisture permeability), silicon resin, and the like, or varnish is used, and coating film is formed. As a result, even if the compounding ratio of the SiC particles of the field relaxation layer 4 is heightened, the SiC particles do not come in direct contact with the air, and by the moisture-proof protective layer 5, the infiltration of water is suppressed, and so good resistance characteristic can be stably retained for a long time.

Filed: 1987-08-20
Abstract: PURPOSE:To miniaturize the titled attenuator, by constituting a variable resistor inserted in series with an input/output terminal of a PIN diode, and the variable resistor inserted in parallel with a line of the PIN diode and a 1/4-wave impedance inversion line. CONSTITUTION:An impedance observing the PIN diode 12 from the connection point of resistors 5 and 6 is inversely proportional to the impedance between the terminals of the PIN diode 10, and a device is operated ideally as a bridging T-type resistance attenuator, and no reflecting wave is generated at the input/ output terminal. In such a way, it is possible to vary a attenuating quantity successively as keeping the impedance of input/output constant by supplying a DC bias current from a bias supplying terminal 9 as controlling it in the bridging T-type resistance attenuator. In the circuit, the attenuating quantity is decreased by increasing a DC current. Therefore, in the circuit, it is enough to prepare one 1/4-wave line whose geometric size is limited, and it is possible to miniaturize the circuit compared with an ongoing attenuator.

Abstract: PURPOSE:To obtain a heat-shrinkable pipe with tapered peripheral surface by a method wherein a wound-around layer consisting in lap-winding a crosslinked synthetic resin tape onto a tape made of a synthetic resin with high adhesion property is fusion-bonded by heating into an integral body on the slant surface of a mandrel. CONSTITUTION:A tape consisting of ethylene-vinyl acetate copolymer (EVA) containing 20-30wt% of vinyl acetate is employed as a synthetic resin with high adhesion property. One layer of an EVA tape is wound around onto the tapered surface of a mandrel 3 tapered along its side peripheral surface with an overlap of about 1/2 of its width. One wound-around layer of crosslinked polyethylene resin tape, which has been stretched by 200-300% in its longitudinal direction in advance, is arranged onto the above-mentioned EVA wound-around layer 4. After that, the wound-around layers 4 and 5 are placed in a constant temperature bath held at 130-200 deg.C in order to be integrally fusion-bonded and then taken out of the constant temperature bath in order to be cooled down to the room temperature. After being cooled down, an integrally formed pipe 6 is taken off from the mandrel 3. The resultant pipe is adhered onto the insulator of cable or the like by heat-shrinking, resulting in forming a coating with high watertightness.
