Title: Manufacture for metal image
Inventor: OONO MAKOTO
IPC: G03F1/68
Filed: 1978-05-31
Abstract: PURPOSE: To establish the metal image of negative type stably, by causing the metallic salt forming reaction with the ion reaction at the boundary of lamination type material with electron beam bombardment and increasing the sensitivity of anti-electron beam.  
     CONSTITUTION: The organic material is made by solving and scattering the organic compound having the performance which can hold the both ion type construction matallically and thermally, to the polymer binder having the performance which can be cross-linked and polymerized with radiant rays and isolates halogen acid thermally. When the organic layer 2 and the metal thin film 3 are laminated on the substrate 1 and the pattern is baked with the radiant rays 4 in strength modulation, halogen acid is made free and diffused at the non-bombarded part. The organic compound scattered is isolated and diffused as ionized state, to cause the denaturated metal layer 3' at the boundary and the coating layer 9 of organic compound. At the bombarded part 2', the appearent specific gravity is increased by cross-linked polymerization and the isolated halogen acid and inoized organis substance are enclosed to block the diffusion. Further, the negative image by metal layer 10 can stably be obtained with selective non-electric plating.

Title: Method for purifying angiotensin converting enzyme
Inventor: KYODA TAKAHIRO
IPC: C12N9/64
Filed: 1988-03-19
Abstract: PURPOSE:To obtain an angiotensin converting enzyme (ACE) with a high purification degree, by linking the ACE in a sample to immobilized iminodiacetic acid groups and then liberating the ACE. CONSTITUTION:In order to bind iminodiacetic acid groups linked and immobilized on the surface of a beadlike carrier, such as glass, to ACE, the iminodiacetic acid groups are previously bound to zinc ions, such as zinc chloride. Excess zinc ions unbound to the iminodiacetic acid groups are then separated. A lung of a rabbit, etc., is subsequently homogenized, etc., and centrifuged to provide a cell membrane fraction, etc., which is then adjusted to afford an ACE-containing sample. The resultant sample is then brought into contact with the iminodiacetic acid groups linked to the zinc ions. The ACE bound to the iminodiacetic acid groups is subsequently liberated and eluted with an eluting solution containing a chelate antagonistic agent, such as glycine. Thereby, the aimed ACE with a high purification degree can be obtained by simple operation. The above-mentioned method is more preferably carried out by especially using column chromatography.
