Abstract: In accordance with the present invention, there is provided a process for depositing diamond-like carbon (DLC) films by cathodic arc evaporation (CAE), wherein the high energy of CAE metal ions causes the cracking reaction of the hydrocarbon gases fed into the vacuum reaction chamber and then results in the deposition of DLC films having high hardness and lubrication. Due to the metallic constituents doped in the DLC films, the films also have good toughness. Moreover, prior to the feeding of hydrocarbon gases for the DLC deposition, the same metal arc source may deposits one or more interlayers of metal, metal nitride, or metal carbide on the substrate so as to further enhance the adhesion of the DLC films to be deposited.

The case is further provided with an upper hole and a lower hole in a corresponding location for a parallel pin receptacle to be inserted and pin sockets to fit in the pin receptacle to electrically connect the computer devices stacked up and supported with the connect plates.

Abstract: A zero insertion force CPU connector is constructed to include a connector body, a plurality of terminals installed in respective terminal slots in the connector body, and a sliding cover covered on the connector body and adapted to support a CPU and carry the CPU into contact with the terminals in the connector body, wherein the terminals each have a head formed of a supporting strip, a springy pressure strip, and a space defined between the supporting strip and the springy pressure strip and adapted to receive the pins of the CPU carried on the sliding cover; the sliding cover has a plurality of bottom rods adapted to force the springy pressure strip of each terminal toward the corresponding supporting strip, enabling the pins of the CPU to be respectively positively maintained in contact between the supporting strip and springy pressure strip of each terminal.

Abstract: A fluid type heating apparatus with safety sealing has a metallic heat exchanging main body, a heating unit embedded within the metallic heat exchanging main body, a plurality of fluid conduits extended along the lengthwise direction of the metallic heat exchanging main body, a groove at the center of the metallic heat exchanging main body and housing the heating unit enclosed by an insulating layer, a front cover at front side of the metallic heat exchanging main body and a rear cover at rear side of the metallic heat exchanging main body. The front and rear cover has a plurality of guiding slots coupled to the conduit to control circulation of the fluid.

Abstract: A four-in-one golf putter mainly comprises a body, two wing parts, and an insertion piece, which are made of different materials in different specific gravities, for organizing various combinations with different positions of center of gravity in order to meet requirements of different golfers.

Abstract: A transparent plastic solder strip being provided with a plurality of solder holes for each accommodating an amount of solder paste therein. These solder holes have a very small diameter and are uniformly and densely distributed throughout the solder strip in a specific pattern, such that a proper density of the solder hole on the solder strip is obtained to always allow sufficient number of solder holes to be covered in an applied area for sufficient amount of solder paste to be melted by laser beams and transferred from the solder strip to islands on a BGA carrier for bonding the carrier to a semiconductor device. It is no longer necessary to register the solder holes with the islands on the carrier to complete the solder transfer.

Abstract: A camera and binocular preamplifier combination and method for photographing distant objects with a relatively inexpensive camera are disclosed. The combination includes a relatively inexpensive camera such as a disposable camera and a relatively small pair of binoculars. One optical system in the binoculars is positioned against the lens of a camera and in general alignment with the camera lens and a photograph taken.

Abstract: A high-speed multi-task system which configures with an industrial personal computer and a numerical controller. The industrial personal computer handles the human-machine interface, visual function and main process control, while the numerical controller controls the movements of hardware and input/output. Conventional serial communication port RS-232 is employed for data transmission between the two sub-systems. The high-speed multi-task system of the present invention is built to work in a real-time extension environment to optimize the control and efficiency of a wire bonding system.

Abstract: The invention, a kind of improved three-way valve structure is to install a ball valve inside the main structure of a three-way valve. The top of the ball valve equips a clip base and the lateral sides of its opening equip guiding tracks. The bottom of a turning bar equips a clip base. After assembling a washer on a tuning bar, it is placed inside the valve majority. The ball valve is installed inside a valve majority by using a guiding bar. The clip groove on a ball valve fits the clip base on a turning bar for positioning. After moving guiding bar backward and placing a washer, finally a positioning ring is fitted for completion of assembly and effect of convenient assembly is achieved.

Abstract: A treadle-type vehicle body forward drive structure comprised of a base plate, a transmission assembly and a treadle structure installed onto the base plate, a gear assembly enmeshing the transmission assembly to the treadle structure, and a position limiting plate that maintains the position of the drive structure on the base plate, with the extending ends of the transmission assembly follower shaft installed to the wheel hubs of the vehicle body rear wheels. When the treadle rod is tamped slightly downwards, a slant-cut fan gear of the treadle structure causes a slant-cut gear and a straight-cut gear of the gear assembly to synchronously rotate, at which time since the straight-cut gear of the gear assembly is enmeshed with a straight-cut gear of the transmission assembly, they in combination cause the rotation of the follower shaft and, furthermore, the synchronous rotation of the rear wheels. As such, the user is provided riding pleasure and options.

Abstract: A snap-in bicycle pedal mainly includes a fastener portion that is screwed to a sole of a bicycle shoe and a catch portion that includes two identical and symmetrical catch bodies separately screwed to front and rear sides of a pedal shaft. Two upward projected catch lips are separately provided at least on top surface of the catch bodies and two downward projected retaining tongues are provided at bottom surface of the fastener portion. The retaining tongues and the catch lips have matched and smoothly curved contours that allow the fastener portion to be easily snap-fitted onto the catch bodies by engaging the two retaining tongues into the two catch lips or disengaged from the catch bodies by rotating the fastener portion relative to the catch portion.

Abstract: An immunity testing device formed of a thin sheet of material folded to three portions, and the two end portions; named “front cover”0 and “back cover”; fold back to different sides of the center part; named base seat; to provide protection on both sides of the base seat. Two absorbent sheets bridged with a test paper are fixed on the side of base seat that's facing the front cover. A hole is present at the position of the first absorbent sheet on base seat for specimen application. The front cover is disposed with observation cover plates at the position corresponding to the test paper and/or water-absorbing sheets for observation of test result as well as for preventing pollution before, and after use. The test paper is pre-embedded with antibodies/antigens to capture the corresponding antigens/antibodies in the test specimen as in Immunity method. The used testing device can be burned down to ensure environmental protection.
