Abstract: On a magnetic tape apparatus (1) with a magnetic head (28) which can be turned essentially through 180 DEG , the magnetic head is fitted on a head support (37) which is rotatably mounted by means of a bearing device (46) on the apparatus and which has a channel (69) leading to the magnetic head (28), through which channel unshielded sections of leads (105, 106, 108) of a cable (107) shielded outside the channel (69) with a shielding (109) are led to the magnetic head (28). The head support (37) in this case consists of electrically conductive plastic and is electrically connected to a reference potential terminal (111) on the apparatus, as a result of which the actually unscreened sections of the leads (105, 106, 108) within the channel (69) of the head support (37) are also shielded against interfering electromagnetic radiations.

Abstract: Edible spreads are prone to microbiological spoilage by a number of organisms, including molds and bacteria as well as by physical changes occurring on storage. While the growth of these organisms and consequently the onset of spoilage can be inhibited by the use of preservatives, some consumers find preservatives unacceptable. We have determined that in edible fat products having a fine water drop spectrum and a fine crystalline fat phase can be produced without preservatives. The invention provides an installation for the manufacture of such spreads a process for the production of such an edible spread which comprises the steps of;
     a) forming a coarse fat-continuous dispersion of water-in-oil, and optionally cooling said dispersion so as to obtain a fat continuous emulsion comprising from 0.5 to 2.5% solid fat,   b) homogenising the product of step (a), and,   c) working and cooling the product of step (b) to obtain an edible emulsion spread.

Abstract: The present invention provides a wide wavelength range optical fiber coupler that to the greatest extent possible, allows optical coupling which is wavelength independent, and thus demonstrates a constant coupling ratio over a wide range of wavelengths. By causing various irregularities (17) to be formed in the fused-elongated region of an optical fiber coupler (16), thereby leading to the generation of additional modes in addition to the fundamental modes, while at the same time causing multiple mode coupling in which the above mentioned additional modes participate in the coupling of the fundamental modes, it is possible to selectively control the coupling strength at determined wavelengths and thereby achieve optical coupling which is largely wavelength independent and thus demonstrates a relatively constant coupling ratio over a wide range of wavelengths. Furthermore, by causing the strength of coupling between the cores of each component optical fiber to vary along the length of the longitudinal axis of each component optical fiber, it is possible to decrease the degree of sinusoidal variation in the wavelength dependance characteristics of each component optical fiber, thereby making it possible to further achieve optical coupling which is wavelength independent and thus considerably constant over a wide range of wavelengths.

Abstract: An apparatus and method for monitoring and maintaining a predetermined width in the gap between a casting nozzle and a casting wheel, wherein the gap is monitored by means of at least one pneumatic gap sensor. The pneumatic gap sensor is mounted on the casting nozzle in proximity to the casting surface and is connected by means of a tube to a regulator and a transducer. The regulator provides a flow of gas through a restrictor to the pneumatic gap sensor, and the transducer translates the changes in the gas pressure caused by the proximity of the casting wheel to the pneumatic gap sensor outlet into a signal intelligible to a control device. The relative positions of the casting nozzle and casting wheel can thereby be selectively adjusted to continually maintain a predetermined distance between their adjacent surfaces. The apparatus and method enables accurate monitoring of the actual casting gap in a simple and reliable manner resistant to the extreme temperatures and otherwise hostile casting environment.

Abstract: A device for measuring the diameter of the growing portions of the single crystals grown by the Czochalski technique is provided. This device is capable of measuring the crystal diameter with a high degree of accuracy over a wide range from the small-diameter portion thereof to the large diameter portion. A one-dimensional camera 28 and a two-dimensional camera 48 are fixed to a shoulder chamber 34 in such a manner that the optical axes thereof are parallel to each other. An optical path switch-over device, consisting of a cylinder 56, a movable plane mirror 52 mounted on a cylinder rod, and a fixed plane mirror 54, is provided. When the diameter of a neck portion of the single crystal 20 having a diameter of 10 mm or less is measured, the light reflected by the plane mirrors 52 and 54 is made incident on the two-dimensional camera 48, and the diameter of a bright ring 27 is measured on the basis of the image obtained by the two-dimensional camera. To measure the diameter of the conical and cylindrical portions 24 and 26 having a diameter of 10 mm or more, an image of a line lying across the bright ring 27 is obtained by the one-dimensional camera 28 by retracting the plane mirror 52, and the diameter of the bright ring 27 is measured on the basis of the position where this line crosses the bright ring. When the two-dimensional camera 48 is switched over to the one-dimensional camera 28, the diameter measured using the one-dimensional camera 28 is corrected such that it coincides with the diameter measured using the two-dimensional camera 48.

Abstract: A defect inspection system for scanning a surface of a test piece to pick up image signals, followed by processing the signals to detect any defects. In order to eliminate noises due to background pattern or topographical feature of the surface of the test piece, spatial-filtering is effected by using a differentiation filter. A background noise discriminator is provided to discriminate the directivity of the topographical feature while referring to the differences in density of respective image signals of the inspected surface, and to define an optimum differentiation filter used for spatial-filtering. In an alternative embodiment, histograms are drawn by plotting the differences to be used for the discrimination of the topographical feature. Also provided is an inspection process in which an optimum differentiation filter is selected by a background noise discriminator and then spatial filtering is effected by using the thus selected differentiation filter not to detect noise signals due to the topographical feature of the test piece.
