摘要:
A magnetic marker comprising a plurality of magnetized fibers oriented substantially parallel to each other is attached to a fringe of ground fabric for production of felt in the form of an endless belt for detecting the travel of the ground fabric and changing various production parameters according to the number of turns which the ground fabric makes around a series of rolls for causing the movement of the ground fabric. Since the magnetic marker consists of extremely thin magnetized fibers, it can withstand the repeated piercing by needles which is required for the production of felt for the purpose of entangling the fibers of fiber web with the ground fabric.
摘要:
A driver drives an X-ray tube and a flat panel X-ray detector synchronously to scan sectional planes to be imaged of an object under examination. A back projection unit projects projection data detected in varied scan positions to predetermined lattice points of a three-dimensional lattice virtually set to the region of interest of the object radiographed. An image reconstruction is carried out to generate three-dimensional volume data of the region of interest. The three-dimensional volume data of the region of interest is generated quickly without repeating a radiographic operation.
摘要:
An X-ray CT apparatus for reconstructing images based on transmitted X-ray detection data acquired by emitting a conical X-ray beam from around an object and outputted from a flat panel X-ray sensor. In advance of CT imaging, a reconstruct area for CT imaging is displayed on a display monitor as superimposed on a fluoroscopic image acquired by irradiating the object with X rays emitted from a selected direction around the object. The operator can determine, before executing the CT imaging, whether a site of interest to be imaged is within the reconstruct area, thereby reliably acquiring CT images of desired sections.
摘要:
The present invention is to provide an apparatus for coating an advancing web on a backup roller Using a coating roller, which enables one to measure and control a coating gap between a lip surface of a coating die and the coating roller. The apparatus includes an extended portion which extends outward from each end of a slit portion of the coating die and has a reference surface parallel to the lip surface, the coating die is slidably located on a frame, a distance sensing means is fixed on each side of the coating roller, a distance is measured from the distance sensing means to the surface of the extended portion and the coating gap is controlled by sliding the coating die in a radial direction of the coating roller. Coating material is thereby controllably transferred from the coating roller to the web.

摘要:
Improved process for the preparation of 7-(2-amino-2-phenyl-acetamido)cephem derivatives of the general formula (I): ##STR1## wherein R.sub.1 is a hydrogwn atom or hydroxyl group, n stands for 0, 1 or 2, and A denotes a nitrogen-containing heterocyclic group or a direct bond coupling directly the sulfur atom and the --(CH.sub.2).sub.n COOH group together, as well as pharmaceutically acceptable salts thereof. The process is not only simple and easy to carry out, but also provides as crystalline precipitate the intended products with a high yield. The 7-(2-amino-2-phenyl-acetamido)cephem derivatives are useful as intermediates for syntheses of antibacterial agents.
摘要:
Substituted or unsubstituted N,N'-dithiobisformanilide compounds are disclosed, where the substituents can be lower alkyl, lower alkoxy, halogen or CF.sub.3. The compounds are vulcanizing agents for diene rubbers. Diene rubber compounds containing a cross-linking amount of the above compounds are also disclosed.
摘要:
A method for preparing NC (numerical control) tapes for use with numerical control machine tools wherein the information required for preparing the NC tapes is divided into three types of information, one type being machine item information, one being tool item information, and the third being drawing information, with the three types being fed into an information processing unit, the first type information being taped, the second type information being either taped or carded, both types of information being adapted for use by the operator so that such information can be selected when needed from a storage area for use and reuse in the information processing unit, the third type of information being adapted for feeding directly into the information processing unit by reason of a movable index operation of an input table and push button operation of function keys mounted on keyboard, by an operator's manual operation thereof based on his discretion.
