The preferred in-line heater utilizes one or more elongated lamps that generate IR radiation as the heating elements. A vessel is provided through which the fluid to be heated is passed. Typically, the vessel is a tube. The tube is preferably a straight single diameter tube, but can be formed in any convenient shape. For ultra-pure fluids, the vessel is formed of an inert or non-reactive material such as quartz. Preferably, the vessel is transparent to the IR radiation generated by the lamps.

Abstract: In a light beam heating apparatus generating a light beam for heating a work, optical energy of the light beam is deteriorated as the lamp is used. The optical energy is controlled by detecting an optical intensity of the light emitted by the lamp. If the optical intensity is decided not to be increased to a desired value due to an increase in arc light source or the like, an exchange of the lamp is cautioned. Thus, a timing of the exchange of the lamp can be decided before the temperature of a work becomes lower than the desired value.

The system broadly includes an omnidirectional light source and an elliptical reflector, wherein the physical parameters of the light source and the reflector are matched to produce a narrowly focused beam of intense radiation. The light produced by the system is coupled into a fiber optic system for delivery to the target area. In one embodiment, a mirrored surface having an aperture therein is placed at a point near the second focal point of the reflector. The aperture is positioned such that only rays meeting predetermined geometrical exit criteria can pass through the aperture and be accepted by the fiber optic located at the second focal point. Those rays which do not meet the exit criteria are reflected by the mirrored surface toward the interior of the cavity.

Abstract: A system for safely removing even a hazardous contaminant from a substrate surface includes a light energy source whose output is controlled to selectively provide components primarily in the visible and infrared spectrum, and a power unit for energizing the light energy source at a desired energy level, pulse width and pulse repetition rate. Proper selection of these parameters permits the energy source to heat the contaminant sufficiently to cause direct carbonization without entering a melt phase, without the need for any precoat medium. Because the resultant molecular decomposition of the contaminant occurs relatively faster than heat transfer to the underlying substrate, substantially no substrate heating results. The light source energy transforms the contaminant to an ash that is removed from the substrate by a vacuum system preferably surrounding the light source. The light source is preferably a xenon flash lamp operated with a pulse repetition rate of between about 0.

Abstract: During a preheating period of a light beam heating apparatus for heating a material locally with a light beam, fans for cooling a lamp for generating a light beam are not operated. A power source supplies current to a lamp. A current detector detects the current supplied to the lamp from the power source. A delay circuit delays a current detection value from the current detector for a predetermined time period and then sends the value to a controller. Then, the controller starts to activate fans for cooling the lamp. Alternately, a temperature detector is provided to detect the temperature of the lamp. When the temperature reaches a prescribed temperature, the controller starts to activate fans for cooling the lamp. Thus, the internal temperature of the lamp reaches the thermal saturation temperature in a shorter period of time, and the optical energy for heating can be stabilized after preheating.

A first and a second focus of the first ellipsoid of revolution are coincident with a first and a second focuses of the second ellipsoid of revolution. The first focus is an emitting one and a gas-discharge light source is positioned therein, and the second focus is a working focus in which a workpiece being treated is placed.

Abstract: A photosensor arranged at the center of a light-receiving end of an optical fiber bundle detects an optical intensity which is converted by a photoelectric converter to an electric signal. Then, the optical energy provided at the optical fiber bundle is calculated based on the signal. On the other hand, a correction coefficient is calculated from optical intensity signals when the lamp is new and when the element in the lamp wears, and the setting value of the output optical intensity of the optical fiber bundle is corrected. Then, the current supplied to the lamp by a power supply is controlled according to a difference between the setting value and the measured optical energy. Thus, the optical energy to be received through the optical fiber bundle is controlled stably irrespective of the change of optical intensity distribution due to wear of the electrode of the lamp.
