A thermal recording head wherein the resistive heater portion thereof is shaped in an 'hour glass' configuration in order to provide accurate control over the size and configuration of the melt produced thereby.

Heating resistor shape in a thermal printhead

A control method for thermal writing with a multiplicity of 'hour glass' shaped heaters is provided which allows accurate and automatic control of multiple melt sizes in each receiving pixel. This accurate melt size for all receiving pixels is provided immediately after startup when heaters have traversed the margin area and the image is to be traversed. Changing office ambient temperature will not change the accuracy of melt size.

Pyrolyzing apparatus for a mass spectrometer includes a sample holder in the form of a small glass rod having in the end thereof a cylindrical depression of a predetermined small volume. The indentation is to be filled with the predetermined quantity of the substance to be analyzed. The rod is inserted into a supporting structure with the sample holding depression immediately adjacent the ionizing chamber of a quadrupole mass spectrometer. Surrounding the end of the glass rod holding the sample is a heater element which is energized in accordance with a predetermined program to rapidly raise the temperature of the sample to a predetermined initial level, then to increase the temperature of the sample in accordance with an exponential curve to a maximum of a predetermined temperature level. The shape of the sample holder is such that, under the influence of the heat, substantially all of the pyrolyzed molecules will be directed into the ionization chamber where the molecules will be ionized. The ionized molecules will then be directed into the quadrupole separator, toward a collector.

Programmed sample pyrolysis for mass spectrometer

A scanning automated microscope system is designed as a clinical laboratory instrument which will aid and speed the task of the medical technologist in performing leukocyte differential count and red blood cell morphology studies. The microscope system has automatic stage drive which operates along the x, y, and z axes and an automated cell find system such that the leukocytes on normally prepared Wright stained slides are located automatically along a conventional meander search pattern, the found leukocytes are centered in the field of view, and are focused automatically. These cells can be observed on a color TV monitor and/or through the microscope oculars.
