Abstract: Method and apparatus for correcting the axial coma in the image created by an electron microscope without requiring skillfulness or any other peripheral device. The microscope is equipped with a beam wobbler and brings the voltage center or current center into the middle of the final image by controlling the deflection coils. The amount of the deviation of the voltage center or current center from the coma-free axis is previously found and stored in an area of a memory. This beam is tilted by the amount of the deviation read from the memory. For this purpose, a deflecting signal corresponding to the amount of the deviation is produced to the deflection coils. Therefore, once the deviation is found, the axial coma can be corrected simply and routinely by correcting the beam tilt by the amount of deviation after the voltage center or current center is brought into the middle of the final image.

Abstract: A furnace for high temperature, for example a glass furnace, is insulated thermally by arranging layers of material on the interior wall of the furnace shell. On the layers ceramic fibre material and a heat reflecting surface layer are arranged. According to the invention, the heat reflecting surface layer is arranged by a substance containing silicon. By subjecting the furnace to great heat and cooling it rapidly thereafter, a heat reflection is obtained in the micro-structure of the ceramic fibre. The substance may for example be water-glass. According to the invention, the fibre material is arranged in vertical blocks of trapezium form, then pressed and strapped up. After all blocks have been placed, one removes the strapping so that the blocks expand.

An adjustable seal is attached to the rear wall of the hopper with a lower edge located below the lower edge of the rear wall of the hopper and depending flapper members are pivotally attached to the front wall of the hopper at each edge to prevent loose material from passing between the sidewalls of the charger plate and the sidewalls of the hopper when the charger plate is reciprocated.

Abstract: A method and apparatus for learning the neutral position of vehicle steering angle, in which first neutral position decision means decides that the steering shaft is at a neutral position when a running speed detector detects that the vehicle speed is not less than a predetermined threshold level, that the difference in peripheral speed between the right and left drive wheels is smaller than a predetermined first straight-running threshold value and also when a steering shaft reference position sensor continues to detect a reference position of the steering shaft for at least a first count time. The vehicle steering angle is computed on the basis of the angular displacement from the neutral position thus learned.

Abstract: A method for the rapid identification and differentiation of HSV-1 and/or HSV-2 with fluorescein-conjugated Helix pomatia lectin. Clinical specimens are processed, with centrifugation, in pre-prepared shell vials of cell culture, with subsequent supplementation and 20 hour incubation (approximately) at 37.degree. C. Coverslips of the shell vials are then fixed, air dried, overlaid with fluorescein-conjugated Helix pomatia lectin, washed, dried, mounted and examined under a microscope equipped with an ultraviolet light source. The identification of fluorescence confirms herpes virus infection. Granular fluorescent patterns confirm presence of HSV-2 serotype and diffuse fluorescent patterns confirm presence of HSV-1 serotype.

Abstract: A Fourier transform spectrometer for conducting Fourier transform spectroscopy. The spectrometer has a light source emitting light to a sample via a rapid scan interferometer. The transmittance of the sample varies when stimulated. A stimulus generator gives a stimulus to the sample at regular intervals of .tau. asynchronously with a reference signal produced for the interferometer. A delay circuit produces a trigger delayed with respect to each stimulation to control a gate circuit. Radiation emanating from the sample is detected by a detector. The output signal from this detector is gated onto a band-pass filter after a given delay .DELTA..tau. with respect to each stimulation by the gate circuit. The gate circuit produces a digital interferogram. The band-pass filter passes only those frequency components which satisfy the condition:m/2.tau.<f<(m+1)/2.tau.where m is a positive integer.
