摘要:
The present invention provides novel tomato lines having disease resistance, and producing a tomato(es) having a weight of at least 140 g with high pigment and reduced blossom end scar size relative to "Suncoast". Due to the reduced blossom end scar size, the tomatoes of the present invention have an increased marketable yield relative to "Suncoast".

The electrical connector comprises a first connector half having a heating element mounted therein. The heating element includes at least one non electrically conductive surface having a set of electrically conductive surface traces mounted on the at least one surface. Also included in the first connector half are a set of first contacts having one end joined to a first portion of the surface traces on the at least one surface. A second connector half is included for mating with the first connector half. The second connector half includes a set of second electrial contacts for contacting a second portion of the surface traces on the at least one surface of the heating element when the connector halves are joined. A coating of solder is applied to the second portion of the conductive surface traces on the heating element or the one end of the second electrical contacts or both. Thus, when the first and second connector halves are joined such that the one end of the second electrical contacts are in contact with the second portions of the surface traces on the heating element, the heating element can be activated, causing the solder to melt and thereafter deactivated causing the solder to cool solidify, joining the one end of the second electrical contacts to the second portions of the surface traces on the heating element.

A method is disclosed for forming haploid tomato plants. Plants so formed are normal, flowering plants but are sterile. Methods are taught of doubling the chromosome number of the haploid plants to form fetile, true breeding diploid tomato plants. Such methods are useful in plant breeding programs to produce new assortments of genes in true-breeding lines without the several backcrossing steps otherwise required.

The invention is a system for securing the data stored within a computer. The system 10 includes a cabinet 11 having a peripheral frame 12 with at least one drawer 22C having a front panel 24C moveable from a closed position to an open position. The drawer 22C is adapted to hold that portion 26 of the computer containing the data to be secured. The system further comprises electrical connector halves 28, 29 mounted in the front panel 24C of the drawer 22C having electrical cables 30 and 31 coupled to the portion 26 of the computer therein. The connectors are adapted to mate with external electrical connector halves 32, 33 attachable thereto. A cover 48, mounted to the cabinet, is moveable from a first position covering the electrical connector halves 28, 29 to a second position allowing access thereto. A lock 63 is provided which is adapted to lock the cover to the cabinet.

Each individual module includes a sealed chamber containing the electronic components being cooled, the liquid cooling medium, and at least one minature evaporator. The evaporator's outer surface area is in direct contact with the cooling medium, so as to maintain it at a desired temperature. Preferably, in order to minimize the weight associated with the liquid cooling medium and in order to compensate for its coefficient termal expansion and the associated internal pressure variation, the chamber may be packed with resilient spheres that will displace a substantial quantity of the cooling medium without a corresponding increase in its effective viscosity (and thus without any substantial effect on the liquid's capability of transferring heat from the components to the evaporator by means of thermal convection currents). The mechanical, electrical and refrigerant connections between the module and the other assemblies of the avionics system are such that the individual module may be readily removed and replaced thereby further enchancing the overall maintainability of the system. An expansion bladder vented to the external environment may also be provided within the chamber.

The invention is an electrical connector assembly particularly suited for coupling or interfacing external wiring to the back plane of a circuit board housing. In detail, the invention comprises a first connector half having a first set of electrical contacts and a second connector half having a second set of electrical contacts. At least one of the first and second sets of electrical contacts is coated or tinned with solder. An integral heater is coupled to the first electrical connector for heating the solder to a temperature wherein the solder can be melted. Thus, the connector halves can be connected such that the first and second sets of electrical contacts are in contact. Thereafter, the contacts can be heated by applying electrical current to the heater so that the solder is reflowed. When the electrical power is terminated the solder solidifies, thus forming a continuous and air tight path between the first and second sets of contacts. To separate the connector halves, electrical power is again applied to the heater to reflow the solder and thereafter, the connector halves can be manually separated.
