Title: High contraste optical memory tape
IPC: G11B7/258
Filed: 1988-04-06
Abstract: A medium in tape form for laser recorded optical information featuring a gelatin layer (25) having a thin black crust (26) at the top of the layer. The crust is formed by developed black irregular silver particles within the top 0.5 micron of the gelatin layer. The remainder of the gelatin layer is substantially clear gelatin and a reflective metallic layer (24) is disposed below the gelatin. The tape (35) may be disposed on reels (31, 49) and may be pre-patterned during formation of the crust with indicia, such as servo track guides (81) or timing marks. User data (18) may be recorded by modification of the black silver particles in the crust with a laser to expose the reflective underlayer. A laser (143) or other light source is used to read data on the medium (141) with optical contrast between the black crust and the reflective metallic layer underlying the gelatin layer which can be observed in recorded spots.

Title: Process for making noble metal coated metallic particles, and resulting conductive materials
Inventor: OSTOLSKI MARIAN J
IPC: H05K1/09
Filed: 1989-08-28
Abstract: A multi-coated step immersion coating process for producing a noble metal coating on a particulate non-noble metal substrate. The invention further includes the resulting coated particles, alone, or incorporated into resin matrices to form electrically conductive products, e.g., adhesives and electromagnetic interference shielding materials. In the coating process, a master plating solution (25) containing the total amount of free noble metal ions required to coat the substrate is divided into a plurality of plating baths (35, 36, 37, 38, 39). From line (24), the substrate is sequentially immersed in each bath (35, 36, 37, 38, 39) to build up the coating. After each bath (35, 36, 37, 38, 39), the substrate is rinsed twice in first rinse sequence (49). After final bath (39), the substrate, via line (66), additionally undergoes second and third rinse steps (67) and (86), respectively, before being dried in step (97).

IPC: D06P1/34
Filed: 1990-01-04
Abstract: Prodn. of a blacking material comprises treating chitosan (1) with the colouring matter of lithospermum root. From a water-insol. chitosan and a gel-form chitosan a fine particulate blacking material and a gel-form blacking material are produced, respectively, when a water-soluble chitosan or a chitosan oligosaccharide, D-glucosamine, or an inorganic or organic salt of these is used, a liq. blacking material is obtd. The colouring treatment is carried out in the presence of water-soluble Na salts, K salts, Mg salts, Ca slats, Ba salts, Zr salts, Fe salts, Ni salts, Al salts or silicates. The fine particulate blacking material is produced by contacting the gel-form blacking material with an alkaline aq. soln. or by pulverising a thin black film formed from the gel-form blacking material. A fine particulate blacking material is produced by dyeing a natural or synthetic polymer material with the gel-form or the liq. blacking material in the presence of the water-soluble salts. The black iron oxide can be dyed by fixing the gel-form or liq. blacking material on its surface in the presence of the water-soluble salts.

Title: Formulations of plant culture media and applications therefor
Inventor: TEASDALE ROBERT D
IPC: A01H4/00
Filed: 1991-11-04
Abstract: An aqueous medium for plant tissue culture is provided including a nutritively effective concentration of reduced nitrogen, preferably in the form of an amino acid such as arginine employed in an amount of from 1.0 to 5.0 mM, and having not more that 1.5 mM NH4<+>. A phosphorus compound at a concentration of at least 2.5 mM measured as phosphate is also included. A chelating agent such as EDTA, and an iron compound present in molar excess over the concentration of the chelating agent are employed to control divalent ion concentrations.

Title: Metal detector for locating metallic body.
Inventor: TAKEMOTO TAKATOSHI
IPC: A63F7/02
Filed: 1993-04-16
Abstract: A detector includes a matrix sensor (20) having a transmission line group (22) and a reception line group (26), and a signal processing system (170) for detecting the existence and position of a metallic body by driving the matrix sensor. The signal processing system scans to send a signal current to the transmission lines and receives a signal from reception lines, and it detects the existence and position of a metallic body on the basis of the reception signal. When a line or lines for which scanning is not made are designated in advance for either one, or a part, of the reception line group and the transmission line group, the signal processor skips scanning of the line or lines, for which scanning is not made, when such line or lines are designated in advance, on the basis of such an instruction.
