Title: Manufacture of n-valerianic acid or its ester
Inventor: YAMATAKA KAZUNORI
IPC: C25B3/29
Filed: 1980-11-06
Abstract: PURPOSE: To obtain n-valerianic acid or its ester suitable for use as starting material for perfume and industrially useful by-products by subjecting industrially advantageous monomethyl adipate as starting material to electrolytic oxidation, distillation, treatment with an acidic aqueous soln. and distillation or esterification and distillation.  
     CONSTITUTION: Monomethyl adipate is electrolytically oxidized in the presence of its alkali metallic salt in methanol as a solvent. The water concn. of the electrolytic soln. is kept at 0.15W3.0wt%. The product is freed of methanol and separated into a mixture of methyl allylacetate with methyl n-valerianate and dimethyl sebacate by distillation. The mixture is treated with sulfuric acid having 40W90wt% concn. to convert the methyl allylacetate into γ-valerolactone and the methyl n-valerianate into n-valerianic acid. This n-valerianic acid is separated from the mixture by distillation, or the mixture is esterified to form n-valerianic acid ester, which is then separated by distillation.

Title: Current lead of superconducting magnet apparatus
Inventor: KAMIIDE TOSHIO
IPC: H01L39/04
Filed: 1991-06-28
Abstract: PURPOSE:To decrease permeation heat of a low temperature side lead using oxide based superconductor, by installing a nitrogen cooling route for discharging vaporized nitrogen gas from a normal temperature terminal side of a high temperature side lead, monitoring the cooling state of the high temperature side lead with a control means, and controlling the flowing nitrogen amount in the nitron cooling route. CONSTITUTION:The cooling state of a current lead is always monitored with a control means 15, and the opening of a control valve 12B is controlled so as to correspond the difference between detected temperature and a reference value. Thereby heat exchange between liquid nitrogen supplied in a high temperature side lead and a current lead is performed while the inside of a high temperature lead is applied to a heat exchange chamber. A low temperature lead 5 is cooled at a temperature lower than or equal to the liquid nitrogen temperature and turned into a superconducting state, by the nitrogen cooling of a high temperature side lead and low temperature helium gas wherein liquid helium is vaporized. Thereby heat permeating the side of a low temperature terminal 5A is decreased. When the temperature of a normal temperature terminal is decreased at the reference temperature, supply of liquid nitrogen Js interrupted, and useless consumption of liquid nitrogen is evaded.

Filed: 1977-12-28
Abstract: PURPOSE:To simplify circuit constitution and improve follow-up characteristics by controlling the positions and speed signals fed back to the servo circuit of a head- positioning linear motor with low-pass- and high-pass filters. CONSTITUTION:When the voltage having been set according to acceleration, steady speed and deceleration is applied to the voice coil of a linear motor via addaptability phase advance circuit 11, position detection signals are generated from position detection circuits 12, 14 and a speed signal is generated from a speed detection circuit 13 through differentiation of the position detection signals. When the change of the speed signal at the acceleration and deceleration of the linear motor is large, the speed signal from the circuit 13 is cut off with an LPF 16 and servo controlling by the feedback of the position signal outputted by the circuit 14 via HPF 15 is accomplished, by which the head is moved to the neighborhood of the target track. When the speed of the linear motor becomes steady, the position signal from the circuit 14 of less change is cut off with an HPF 14 and the servo controlling by the feedback of the speed signal is accomplished.
