This invention provides a soldering iron that heats the tip and emits inert gas near the tip. This is accomplished by providing a heater cartridge having a top or tip end and a base end with a soldering tip at the top end, an input opening closer to the base end and an output opening closer to the top end. The soldering iron also includes a gas injector having a gas chamber adapted to receive the heater cartridge such that the input opening of the heater cartridge is within the gas chamber so that gas is injected into the input opening. At least a portion of the top end and the output opening of the heater cartridge is enclosed with an exhaust pipe to form a gas passage between the outer surface of the heater cartridge and the exhaust pipe. As such, gas injected through the input opening passes through the opening within the heater cartridge and exit through the output opening, then pass through the gas passage and emit through an outlet defined by the space between the top end and the exhaust pipe to provide inert gas near the tip.

A device and a method for at least partial removal of electric charges from dielectric surfaces (30), in particular surfaces of plastic films, paper webs or plastic fibers are described. First, a plasma is generated through microstructure discharges with a plasma device (1) in at least one plasma region (12, 40). In addition, the dielectric surface (30) is introduced into the plasma region (12, 40) with a feed mechanism (2) and is temporarily exposed to electrically charged particles generated by the plasma there.

There are provided an apparatus and an associated method for manufacturing superplastically formed structural assemblies from preforms. The apparatus includes first and second co-operable dies structured to define a die cavity therebetween for at least partially receiving the preform, at least one heater in thermal communication with the die cavity for heating the preform to a forming temperature, and at least one injector in fluid communication with the die cavity. The injector is structured for injecting pressurized gas into the die cavity to urge the preform against one of the dies to form the preform into the structural assembly. Further, at least one of the injectors is structured for injecting a quenchant into the die cavity to thereby heat treat the structural assembly while distortion of the structural assembly is being at least partially restrained by at least one of the dies.

A portable heat sealer for sealing heavy grade thermoplastic films comprises a plurality of adjacent, segmented heating elements positioned along the underside of a heated sealing bar. The segmented heating elements are under the control of a microprocessor for controlling the energy applied to the heated sealing bar to avoid the formation of hot spots and to obtain a strong seal. Each heating element is maintained in firm contact with the heated sealing bar by means of a tension spring. A thermoplastic film bag is placed on the heated sealing bar and a movable sealer jaw is lowered on top of the bag. A jaw switch is activated by the sealer jaw which turns-on power to the heat sealer. A latch 32 attaches to a clip on the end of the sealer jaws and secures the sealer jaw in place. Pilot lights are provided to indicate to an operator the cycles of nullreadynull, nullheatnull and nullcoolnull.
摘要:
A flexible circuit board (20) having a substantially rigid substrate (22) and an electrical resistance heater trace (24). The substantially rigid substrate (22) has a first portion (26), a second portion (28), and a bend region (30). The bend region (30) interconnects the first portion (26) and the second portion (28). The electrical resistance heater trace (24) is formed on the bend region (30) of the substrate (22). The first portion (26) of the substrate (22) is capable of being folded relative to the second portion (28) of the substrate (22) to form at least one bend (72, 172) in the bend region (30) when an electric current is applied to the heater trace (24). There is also an electronic control unit (60, 160) that includes the flexible circuit board (20) and a method of assembling an electronic control unit (60, 160).
摘要:
A plurality of flash lamps are covered with a reflector. Optical fiber members are attached to the reflector on portions located immediately above the flash lamps. When the flash lamps emit flash light toward a semiconductor wafer, the optical fiber members partially guide the emitted light so that a CCD measures the intensity of light emitted from each of the plurality of flash lamps. A computer detects the emission state of each of the plurality of flash lamps on the basis of a result of measurement. At this time, the computer compares standard luminous intensity obtained when the irradiation state on the semiconductor wafer satisfies a prescribed criterion with the luminous intensity in actual processing for detecting the emission states of the plurality of flash lamps. Thus provided is a thermal processing apparatus capable of reliably and simply detecting deterioration of lamps.

An apparatus and method provided for utilizing radiation pressure provided by a light wave to generate mechanical work. The apparatus includes a containment chamber constructed to contain the propagation of light waves therein along a predetermined reflected light wave path. The apparatus also an optic switch selectively operable in an open mode and a closed mode, wherein the open mode allows a light wave to enter the containment chamber and the closed mode prevents escape of the light wave from the containment chamber. Further, the apparatus has a reflective mirror positioned at one end of the containment chamber. The reflective mirror has a first reflective surface. The apparatus also includes second reflective surface positioned at a second end of the containment chamber, wherein the predetermined light path extends between the first and second reflective surfaces; and wherein repeated contact of the light path against the first reflective surface allows radiation pressure repeatedly acting upon the first reflective surface to cause the movable reflective mirror to travel along a predetermined path, thereby producing mechanical work.

An upper heat roller with an external heat source and a lower heat roller with an internal heat source are arranged with a paper transport path therebetween, in such a manner as to be pressed against each other. The lower heat roller is heated sufficiently, thereby supplying a paper sheet with sufficient heat when the paper sheet is transported through a contact region between the upper and lower heat rollers to be heated.
