Abstract: A method for the manufacture of silicone rubber moldings comprises the preparation of a silicone rubber composition by blending an organoperoxide having an activation energy of 25 to 41 kcal/mol into a semicurable organopolysiloxane composition whose main component is an organopolysiloxane having organoperoxide-crosslinkable functional groups.  The silicone rubber composition is made into a particulate form and heated at a temperature below 100 degrees Centigrade to produce a semicured, particulate molding material which retains the activity of the organoperoxide and which contains residual crosslinkable functional groups on the organopolysiloxane. Subsequently a mold is filled with the molding material and the mold material is completely cured at a temperature of at least 100 degrees Centigrade under the application of pressure.  The method is particularly useful for automatic molding methods.

Title: Optical disk and optical disk drive
Inventor: FUJI HIROSHI
IPC: G11B7/24097
Filed: 1991-11-15
Granted: 1997-10-14
Abstract: An optical disk according to the present invention has thereon an uninterrupted preformed groove adjoining a track.  The address information of the track and sectors is prerecorded by variations in the preformed groove in a radial direction of the optical disk.  An optical disk drive converts a detection signal, that is generated when the spot of a light beam crosses the track, into a binary signal  in  accordance  with  the  comparison  between  the detection signal and two different slice levels, whereby a correct  track  crossing  number  is  obtained.   Another optical disk has thereon index marks that are prerecorded by partially varying the width of the preformed groove.          Another optical disk drive detects the index mark on a specific track line, whereby formatting data with respect to address information is generated.  The optical disks and optical disk drives are thus compatible with writing of the address information by means of soft-formatting.

Granted: 2003-01-28
Abstract: A joint and a laminate including a nickel-titanium alloy such as nitinol and a method for preparing the surface of a nickel-titanium alloy member for bonding solder material and, electively, another similar or dissimilar member thereto. The method includes applying an aluminum paste flux to the titanium oxide coated surface of a nickel-titanium alloy member and heating the flux to its activation temperature. The flux removes and suspends the titanium oxide therein along with leaching titanium from the base alloy member surface to form a nickel-rich interface surface. The activated flux also coats the nickel-rich interface layer for protection from further oxidation. A bonding material such as a tin-silver solder is flowed onto the nickel-rich interface surface to displace the activated flux. Electively, another member is applied to the molten solder to form a joint between the two members. The residual flux is cleaned from the joint to prevent further deterioration of the base metal. The solder joint includes the base nickel-titanium alloy metal, the nickel-rich interface surface, and the solder material. Electively, any other member may be applied to this joint in the molten state to form a metallic bond therebetween.

A transistor control unit is coupled to the gate terminals of the first, second, third and fourth MOS transistors for biasing the transistors for alternately flowing current through the first and fourth MOS transistors or through the second and third MOS transistors   A first transmission line is coupled to the first output node, and a second transmission line is coupled to the second output node.  A terminating resistance is coupled to the first transmission line and to the second transmission line for preventing signal reflections on the first transmission line and the second transmission line.  The first transmission line is coupled to a first input terminal of an ECL circuit element, and the second transmission line is coupled to a second input terminal of the ECL circuit element.  The signals on the first and second transmission lines are used for driving the gates in the ECL circuit element.  A source resistance is coupled between the first voltage node and a voltage source.  The source resistance ensures that the voltage at the first and second output nodes do not exceed the saturation values of the driven ECL gates while simultaneously maintaining a strong differential signal across the first and second output nodes.

Abstract: Analogs of botanic seed are disclosed.  According to one embodiment, a seed analog comprises a unit of totipotent plant tissue disposed relative to a unit of non-phytotoxic hydrated gel that is "oxygenated,"  i.e., has a concentration of molecular oxygen that is higher than a concentration of molecular oxygen that would otherwise be absorbed from the atmosphere by the hydrated gel at standard temperature and pressure. Gel oxygenation can be by exposure to a gas having an enriched concentration of molecular oxygen relative to the earth's atmosphere or by including in the hydrated gel an oxygen-carrying or oxygen-absorbing compound such as a perfluorocarbon and/or silicone oil. An outer shell can be included that, with the hydrated gel, forms a capsule enclosing the unit of totipotent plant tissue. According to another embodiment, the seed analog includes a shoot restraint that is resistant to penetration by a growing shoot and/or cotyledons. In such seed analogs, the unit of totipotent plant tissue has a shoot end, and the restraint is disposed relative to the shoot so as to prevent, during germination of the totipotent plant tissue, entrapment of the shoot end in the seed analog.  Also disclosed are corresponding methods for germinating totipotent plant tissue and for manufacturing seed analogs, all of which especially are useful for producing large numbers of genetically identical plants.

Abstract: A coil spring assembly is disclosed for use with motor vehicle suspension systems in which a portion of the wire coils of the coil spring is covered by a flexible hose or tube. Coil springs which could use such hoses include those having a tapered wire diameter wherein one end of the coil spring's wire has a smaller diameter than at other portions of its length. The flexible hose is made of a material which has sufficient resiliency to first be stretched as it is installed onto the wire of the coil spring, and then will naturally return back to near its original non-stressed diameter to tightly fit around thediameter of the wire at both ends of the hose. The resulting tight fit retains lubricant and anti-corrosive compounds inside the hose, and keeps moisture and dirt from entering the interior of the hose.
