摘要:
A heat exchanger is provided with a first tank and a second tank. Heat transfer tubes are disposed between the tanks and are connected to the tanks to place the tanks in fluid communication. At least one of the tanks is divided into chambers by a partition. A reinforcement plate member is disposed in at least one of the first and the second tanks for reinforcing the tank to prevent deformation of the tank due to an increase of the pressure within the tanks. The reinforcement plate member is not connected to the partition.

A process and apparatus for producing a diamond film from a gas phase, in which a fuel gas is burnt by oxygen gas in a torch, to thereby provide a gas flame jet having a high temperature and high speed sufficient to form a high quality diamond film on a substrate, by an unlimited use of various kinds of combustible carbon compound gases as the fuel gas. A process and apparatus for producing a diamond film from a gas phase, in which a thermal spray material is fed to a combustion flame to thereby form an intermediate layer of a mixture of the thermal spray material and diamond between a substrate and a diamond film, to thereby provide a high purity diamond film having an improved adhesion to the substrate.

A multi-layered type heat exchanger for a refrigerant fluid circuit is disclosed which includes a plurality of substantially parallel flat tubes. Each flat tube includes a partition wall for dividing its interior into two fluid passages. A plurality of fin units are disposed between the plurality of flat tubes. A header pipe has a plurality of slits for inserting upper ends of the flat tubes, respectively, and at least one partition wall to divide the interior thereof into at least two chambers. A seal member sealingly closes lower open ends of the flat tubes. Thus, since the height and length of the flat tubes can be easily adjusted, various sizes and designs of heat exchangers can be easily and cost effectively produced.

A plurality of cutting tips are mounted on the distal end of the cylindrical main body of a drilling tool for performing trepanning. These tips are disposed along the circumferential direction of the main body and equidistantly spaced apart from one another. The force, which is produced by all of the cutting tips and acting at right angles to the axis of the main body, is smaller than the component of the cutting force, which is produced by each tip and acting at right angles to the axis of the main body. The cutting widths of the tips in the radial direction of the main body are substantially equal. One of the tips, which is located at an intermediate position in the radial direction, has a V-shaped leading portion.

A computing unit computes a computed value for input data. A comparing unit compares the computed value of the computing unit with a computed value of another node which is included in an input/output set. An output unit outputs the computed value as output data of a node itself when the result of the comparison by the comparing unit shows that the computed value matches either one of computed values. When the computed value does not match any one of the computed values of other nodes, a transferring unit adds the computed value of the node itself to the input/output set, and transfers the input/output set to another node.
