PURPOSE:To prevent a sheet material having the last end fixed from cut-off or the like by foreseeing and calculating pulse signal ratio at the time of completing supply of the sheet material from rotational pulse signal ratio at the supply starting time to stop or slow down the supply of the sheet with the coincidence of both pulse signal ratios with each other. CONSTITUTION:In an embodiment of a ...

PURPOSE:To prevent a sheet material having the last end fixed from cut-off or the like by foreseeing and calculating pulse signal ratio at the time of completing the supply of the sheet material from rotational pulse signal ratio at the time of starting the supply to stop the supply the sheet material when said both pulse ratios coincide with each other. CONSTITUTION:In an embodiment of a microfil...

The method and device detect, in particular, surface faults such as cracks on hot, descaled continuous casting products. Fitted in a continuous casting machine is an optronic sensor, for example an electronic camera with electronic high-speed exposure past which the products to be inspected are conveyed. The optronic sensor receives the surface radiation emitted by the products and converts it int...

Aqueous cellulosic slurries comprising primary binder, newsprint, sulfite pulp, and vegetable shell flour can be prepared and formed as desired into various configurations. The materials thus formed are usable for a variety of purposes including furniture, paneling and flooring structures.

A process for producing a binder (cement) to be used in slurry, mortar, or concrete having a low water-to-cement ratio. As raw-material for the binder is used at least 50% by weight of a hydraulic material, such as slag, technical pozzolanas and/or natural pozzolanas. The hydraulic material is ground to a specific surface of at least 400 m2/kg. To the raw-material is added 0.1 to 5% by weight of a...

Prostanoic acid derivatives represented by the general formula: in which X represents hydrogen or hydroxy, X1 represents hydrogen or X and X1, when they are taken together with the carbon atom to which they are attached, represent a carbonyl group and Z represents hydrogen or hydroxy and pharmaceutically acceptable alkali metal salts thereof. They can be used as bronchodilators and/or in...

PURPOSE:To enable to prevent a semiconductor element base plate to be adhered and fixed to a package from a potential variation by a method wherein a capacitor having a function as a smoothing capacitor is formed by the package itself for the semiconductor device. CONSTITUTION:The conductive mounting part 2 of a package is made as the electrode on one side of a capacitor, a conductive layer 8 is m...

PURPOSE:To enable to improve sharply thermal resistance of a resin sealed semiconductor device by a method wherein a recess part is provided on the surface of the resin sealed body, and a radiator board consisting of a favorably thermally conductive material is equipped thereto. CONSTITUTION:A recess part is provided on the upper surface of a resin sealed body 1 in a sealing process, and a copper ...

An apparatus for ascertaining the extent of deviation of the actual position of a hole in a bulky workpiece from the desired position has a mandrel which is reciprocable to move its conical tip into and from the opening. The tip is followed by a main portion which fits snugly into the opening. If the hole is out of position, the mandrel is shifted laterally during penetration of its tip into the h...
