	Microtome - Patent 5752425
		A microtome as defined in claim 1, wherein said first feed means of said micro-feed mechanism is constituted by a first fixed member securely fixed on said machine base and a first movable member mounted movably on top of said first fixed member for movements in a direction at an angle of +.theta.
		In the case of the microtome of the arrangements just described, the first and second linear motor stages are displaced in two intersecting directions crossing at an intersection angle of 2.theta., and the specimen holder support arm is located in an upper lifted position in an initial state in the direction of Z-axis.
		The microtome 1' of the arrangements just described operates substantially in the same manner as the microtome 1 of the foregoing first embodiment except that the cutting knife 6' is finely fed by the micro-feed mechanism 7.

	Microtome - Wikipedia, the free encyclopedia
		Cryosections can also be used in immunohistochemistry as freezing tissue does not alter or mask its chemical composition as much as preserving it with a fixative.
		Electron microscopy: after embedding tissues in epoxy resin, a microtome equipped with a glass or diamond knife is used to cut very thin sections (typically 60 to 100 nanometers).
		A recent development is the laser microtome, which cuts with a femtosecond laser instead of a mechanical knife.

	The microtome: function and design © Woods and Ellis 2000
		The distance moved is pre-selected using a scale setting on the microtome body and usually extends between 0.5 and 50 microns on microtomes cutting thin sections and from less than 60 nm to over 500 nm on machines cutting ultra thin sections.
		The microtome operation is based upon the rotary action of a hand wheel activating the advancement of a block towards a rigidly held knife.
		Microtome knives of hardened steel are made to four different profiles for cutting various materials (Fig 7).

	Neurogenetics at UT Health Science Center
		Estimations of the numbers of nuclei in microtome sections are frequently made in some branches of histology, particularly in the study of endocrine glands, hemopoietic organs and the central nervous system.
		Since microtome sections are commonly roughly the same thickness as the nuclear length, the error in extrapolating from A to the number of nuclei per unit volume of tissue may often reach 100%.
		The error in comparing on the basis of counts in sections two tissues whose nuclear size is different is much less serious, since it follows from equation (1) that a given change in L produces a disproportionately smaller change in A when P is held constant [RW2].

	Cutting It Fine
		Microtomes are devices for cutting very thin slices to be examined under the microscope.
		The largest microtome in the collection, shown in Figure 5, is also by the Cambridge Instrument Co. It is a lever-operated sledge microtome of a design introduced in 1909 which could cut specimens such as bones in sections up to 40 square cm.
		The Museum holds two microtomes of Japanese manufacture, a rotary instrument by Y. Takahashi and a radial instrument by J. Oiso and Co. Both were made in the Hongo district of Tokyo (where the University of Tokyo is located) and possibly date from the 1920s.

	Microtome Knife Sharpener
		The goal of this holder design is to minimize the operator skill needed to sharpen a microtome knife, necessary since I had never seen a microtome knife prior to sharpening this one.
		In use, the upper end of the hone or strop is kept in contact with the upper block while the abrasive section of the tool is in contact with the knife, thus ensuring that the angle built into the holder is transferred to the knife.
		In my microtome the knife can only be moved a short distance sideways before it cannot be clamped, so only the central 3 inches or so of the knife could possibly be used.

	Microtome Publishing
		With open access print archiving, an open access journal prepares annually a copy of all articles it has published during the year; copies are then printed on acid-free paper, bound to library standards, and distributed to a set of libraries to serve not as access copies but as archival copies for long-term deposit.
		Microtome Publishing was founded by Stuart Shieber, Welch Professor of Computer Science at Harvard University, to provide just such innovative services in support of open access.

		Colin suggested that a sheet of 6mm thick plate glass, cut to a width appropriate for the particular length of knife, could be usefully employed as a knife-sharpening surface.
		were invited to practice section cutting with their own microtomes Colin demonstrated how to attach wax blocks to the block-holder (also known as the 'chuck') of the microtome, using a heated spatula.
