Title: Preparation of pure unsaturated fatty acids
Inventor: GOFFIC FRANCOIS LE
IPC: C07C67/54
Filed: 1999-06-01
Abstract: A process for producing highly concentrated preparations of polyunsaturated fatty acids and their esters from oils, especially fish oils, in which they occur mainly as their triglyceride esters. The process uses a combination of transesterification of the triglycerides with a lower alkyl alcohol, molecular distillation and selective enzymatic transesterification with an alkoxy alcohol catalysed by lipases which desirably can be immobilized. The process permits the separation of the acids mixture usually encountered in the oils, and isolation of desired acids in high yields. Typical acids which can be obtained by means of this process are eicosapentaenoic acid (EPA, C20:5) and docosahexaenoic acid (DHA, C22:6).

Title: Magnetic recording medium and its production
Inventor: GOMI MANABU
IPC: G11B5/84
Filed: 1983-01-25
Abstract: PURPOSE:To increase the magnetic anisotropy in the direction perpendicular to a film plane and to improve a magnetic characteristic by having a CoCr alloy film, forming the film of the aggregate of independent columnar crystal grains, and etching the surface thereof thereby obtaining a magnetic recording body. CONSTITUTION:A magnetic recording medium is formed by forming a CoCr alloy film 1 by a sputtering method on a base plate 2, and subjecting the CoCr alloy film to chemical or electrochemical etching by an acid as a post treatment. The shape anisotropy by the etching can be added to the crystalline magnetic anisotropy provided intrinsically to the CoCr alloy film and therefore a perpendicular anisotropic magnetic field Hk can be increased with the natural magnetized Ms as it is, so that the good vertical magnetization film is obtd. Such magnetic anisotropy is generated as the columnar crystal grains (the C axis thereof is perpendicular to the plate 2) of the film are respectively isolated by the etching. Saturation magnetization is maintained perpendicularly to the film plane by the generation of such magnetic anisotropy, even if the magnetic field is zero. The magnetization curve has thus a large squareness ratio.

Title: Cyclic on/off control oscillator
Inventor: FUNADA TAKAYOSHI
IPC: H03B5/06
Filed: 1994-02-01
Abstract: PURPOSE:To reduce an oscillation output start-up time and to prevent adverse effect such as leakage of oscillation to a peripheral circuit by applying on/off control to the operation of an active element cyclicaly. CONSTITUTION:Since an oscillated output rises in a smaller delay time than an oscillation output rising delay time being a time from OFF to ON simply when the oscillated output is subject to on/off control by having only to apply on/off control to a power supply for an active element 1 cyclicaly, the oscillation output rising time is reduced. Furthermore, the oscillation is controlled completely stopped when the active element 1 is turned off. When the oscillator is used for a TDMA system radio communication whose transmission and reception frequencies are identical, since the oscillation is completely stopped in a reception time slot of a concerned station and the oscillation starts up in a transmission time slot, the internal interference between transmission and reception is prevented.

Abstract: PURPOSE:To easily measure an interference at a low cost without using an expensive beam splitter by making light radiated from the front and the rear of a light emitting element interfere with each other on an object to be measured. CONSTITUTION:In the case of an interferometer for measuring a deformation due to heat or the like, light radiated from the front 1a of a semiconductor laser element 1 is made a parallel beam by a lens 2, light from the rear 1b of the element 1 is similarly made parallel beam by a lens 3 and the two parallel beams are reflected by mirrors 4 and 5 to irradiate an object 6. The image of the object 6 is formed by a lens 7 on the screen 8 of a CCD camera. The image after the sequential deformations is superposed on the image before the deformations stored in a frame memory 9, the state of an interference is measured in real time and an observation is monitored on a CRT 10. Thus, an expensive beam splitter is not required to reduce the cost of an instrument and, since light radiated from the front and the rear of the semiconductor laser element is used, setting interference conditions is facilitated.
