Patent EP-0258451-B1 (EP)
IPC: H05K3/20
Filed: 1987-02-21
Granted: 1993-10-13
Abstract: A thin metal layer is formed by electrolysis (S2) maintaining a thickness of 1 to 5 mum on an electrically conductive single-plate substrate having a predetermined coarseness, a resist mask is formed (S3) on the surface of the thin metal layer, and then a conductor circuit is electroformed thereon (S4) using copper. After the surface of the conductor circuit is coarsened (S5), the conductor circuit is laminated on an insulating substrate for each single plate via the thin metal layer and is intimately adhered in a unitary structure by the application of heat and pressure (S7). Then, the single plate only is peeled off (S8), and the exposed thin metal layer is removed by etching (S9). The thin metal layer and the conductor circuit are electroplated at high speeds under the conditions of a liquid contact speed of 2.6 to 20 m/sec. and a current density of 0.15 to 4.0 A/cm2, so that a required intimate adhesion force is obtained between the thin metal layer and the resist mask. Further, the conductor circuit is provided with flexibility like that of rolled and annealed copper, thus making it possible to produce very thin and high-density conductor circuits having a thickness of smaller than 10 mum adapted not only to rigid printed wiring boards but also to flexible printed wiring boards.

Title: A controlled-release composition for a biologically active material dissolved or dispersed in an l2-phase
IPC: A61K9/52
Filed: 1987-06-12
Granted: 1992-04-01
Abstract: A controlled-release composition for a biologically active material, wherein said active material has been dissolved or dispersed in an L2-phase comprising: (a) at least one monoglyceride of an unsaturated fatty acid having 16-22 carbon atoms or a vegetable or animal oil containing such a monoglyceride, (b) at least one triglyceride of at least one unsaturated fatty acid having 16-22 carbon atoms or a vegetable or animal oil containing such triglycerides and (c) at least one polar liquid selected from the group consisting of water, glycerol, ethylene glycol and propylene glycol. Such L2 phases are known per se but are novel in this context. The composition is prepared by forming the L2 phase and adding the biologically active material before, during or after the formation of the L2-phase. For sensitive substances such as proteins a mixture of the mono- and triglycerides is added dropwisely to a solution of said substance in the polar liquid. The invention also relates to the use of this specific L2-phase to encapsulate a biologically active material.

Granted: 1991-07-24
Abstract: Process for preparing magnetic recording material by depositing ferromagnetic material in particulate form into an aluminum substrate. The aluminum substrate is prepared by cleaning an aluminum or aluminum metal containing substrate; anodizing the cleaned metal substrate, to produce a suitably pitted or porous oxide substrate surface; and rinsing the anodized substrate,substantially to remove therefrom acid residues remaining from the anodizing step. The substrate in contact with a liquid solution of a salt of at least one ferromagnetic metal is then subjected to electrolysis with alternating current, to deposit the metal into the pores of the oxide in small-particle, ferromagnetic form while adjusting and controlling the frequency of the alternating current to obtain discrete particles in the pores assembled in an anisotropic configuration. Excess liquid solution is subsequently removed from the so-treated substrate. The material is then preferably coated with a suitable resin or polymer to seal the pores and then polished to generate a suitable surface for reading or writing by magnetic heads.

The subject device includes, within a housing-body communicating with the outside only by means of a lower slot through which the paper strip is made available to the users close to a blade for severing the desired length of paper, a substantially unsymmetrical S-shaped member (8) fastened, at an area intermediate between the two portions (8a, 8b) of said S, to a pivot shaft (9) rotatably mounted on said housing (1) and connected to rotation driving means (12a, 32, 15) thereof, which rotations result in rotations of said S-shaped member (8). The smaller portion (8a) convex side provides support for the spare roll (20 min ), possibly in combination with other shaped member integral with the housing (1). When the S-shaped member (8) is rotated, it drops said roll (20 min ) in the underlying area, wherein it is collected by the concave side of the larger portion (8b) which guides the roll (20 min ) towards the operational unrolling area, cooperating with stationary guide means integral with the housing (1).

Abstract: Low concentrations of the protein kinase C activators, bryostatins 1 and 2 synergized with rBSF-1 are useful in triggering differentiation (granule enzyme expression) and CTL development in naive, resting lymph node T-cells. Bryostatin greatly enhances efficiency of rIL-2 in triggering development of in vivo primed CTL during in vitro incubation, thereby providing evidence for the use of lower concentrations of rIL-2 for in vivo tumor rejection. Both bryostatin 1 and 2, trigger cytotoxicity of CTL clones against Ag-non-bearing target cells and inhibit CTL cytotoxicity against Ag-specific target cells. Bryostatin 1 and 2 synergize with Ca<+><+> ionophores in triggering the exocytosis of cytolytic granules from CTL at very low concentrations. Because of the lack of tumor promoting activity in the bryostatins, they are useful per se as immunomodulating drugs and as potentiators for rIL-2 in adoptive immunotherapy. <CHEM> y
