Patent EP-0494259-A1 (EP)
Title: Temperature control of a heated probe.
Inventor: MASRELIEZ C JOHAN
IPC: A61C5/04
Filed: 1990-09-27
Abstract: A method and apparatus for precisely controlling the temperature of a heated tip are disclosed. The temperature of a thermocouple within the tip is sensed at a selected rate. The sensed temperature is compared with a preselected temperature set by a user. The power provided to heat the tip is varied to cause the tip to achieve the selected temperature. If an AC power source is used, the temperature sensed at each zero crossing of the power source and the amount of power provided within that cycle is based on the temperaature of the tip sensed within the same cycle. The duration of time that heat is applied to the probe within the cycle is varied to achieve the desired temperature. If a DC power source is used, the temperature of the tip is sensed at selected intervals. The sensed temperature controls the amount of power provided to heat the tip. The exact temperature of the tip is thus advantageously controlled to provide the desired heating.

Abstract: An annular space heat exchanger, which consists of at least three tubes (2-5) arranged concentrically one inside another, so that there are produced between the individual tubes annular spaces or annular chambers (7-9), through the respectively inner one of which the heat carrier, and through the respectively outer one of which the heat-absorbing medium flows, the heat carrier being gas, and the heat-absorbing medium a liquid medium, is to be constructed such that as high an efficiency as possible is achieved in conjunction with universal usability of the heat exchanger. Furthermore, it is to be possible to produce the heat exchanger with as low as possible an outlay on manufacturing. According to the invention, it is provided for this purpose that the heat-carrying medium is subjected in the inner annular chamber to a helical flow which conducts the medium around the inner tube. <IMAGE>

Abstract: In order to heat an injection head for a plastic injection moulding machine by means of high frequency during injection, the injection channel is designed as a slit 6, the opposite walls of which are designed as high-frequency electrodes to which the two poles of a high-frequency source are connected, and the plastics material 3 flowing through is heated dielectrically. As a result, with the same flow volume, the same power or energy input is attained at a lower voltage. In an advantageous way, the injection channel is designed as an annular slit 6, by a tube 1 forming the one electrode and an inner conductor 5, suspended in an insulated manner in the said tube, forming the other electrode of a high-frequency capacitor. <IMAGE>

Abstract: A light absorbing layer (2b) and a window layer (2c) formed thereon constitutes a first conduction-type semiconductor layer (2). In a part of this first conduction-type semiconductor layer (2) there is provided a second conduction-type region (3) extending to the light absorbing layer (2b) through the window layer (2c). A part of the window layer (2c) around the second conduction-type region (3) is selectively removed. Consequently, even when light intended to enter a light detecting region (8) is incident outside of the light detecting region (8), most of the carriers generated there are recombined at a surface level of the light absorbing layer before diffusing in a depletion layer. Therefore, this light detecting device does not substantially show detection sensitivity to light incident outside the light detecting region (8).

Abstract: Video signals for each primary color are delayed in time relative to every other primary color video signals. When displayed on a cathode ray tube ("CRT") display, the time delayed video signals will result in a separated color pattern for each image displayed. Separated color images are subsequently realigned through use of electron beam deflection controls affecting the horizontal and vertical displacement of electron beams for each color. Measurement of EMI at a far field point varies between zero (no EMI) and no reduction in measurable EMI, depending on the frequency of the video signals and the amount of time delay induced therein. In alternative embodiments, time shifting of video signals may be accomplished either by discrete filter components, simple propagation delay lines.
