摘要:
A remote supervisory and controlling System for remotely supervising and controlling loads in time-divisional multiplex transmission of control and monitor data between a central control and terminal units each connected to the central control unit through a two-wire line. Supervision and control of the overall system can be carried out from a plurality of locations so that failure of a central or host computer will not render the overall system inoperative.

A nutrient comprising fats and oils having superior digestibility and absorptivity are provided, which fats and oils are comprised of at least one triglyceride having fatty acids of C.sub.8 to C.sub.14 at the 2-position of the triglyceride and identical unsaturated acids of C.sub.18 or higher at both the 1- and 3-positions thereof. Examples of the unsaturated fatty acids of C.sub.18 or higher are linolic acid, linolenic acid, arachidonic acid, eicosapentaenoic acid, and docosahexaenoic acid.

Process for preparing NbN superconducting material, characterized in that a bulk Nb is placed in powder including at least one metal which can be nitriding-burned, and then the powder is heated to be nitriding-burned in pressurized N.sub.2 atmosphere so that the bulk Nb is nitrided by the nitriding-burning of the powder.
摘要:
An inspection apparatus for inspecting printed circuit boards on which components have been mounted, wherein a light source that generates a light beam in a concentrated spot fashion is mounted on a rotary object and radiates the beam spot onto the printed circuit board at approximately right angles thereto while the rotary object is rotating, so that the surface of the printed circuit board is scanned by the beam spot. Changes of at least either one of the reflection angle and the intensity of the light reflected from the printed circuit board is detected by photoelectric converters provided on the rotary object, and at least either one of the height and the brightness of the position at which the beam spot and the printed circuit board are intersected is measured, thereby performing the inspection of the printed circuit board.

A random multi-error correcting code having a maximum length block in a packet, for instance a majority logic decodable (272, 190) shortened difference set cyclic code, is used for error correction in a character code broadcasting system. The error correcting ability of this code is increased. The correction is made by decreasing a threshold value, so that the error correcting ability is improved. A framing timing extraction circuit and a phase lock circuit for the framing timing are eliminated, so that the amount of hardware needed is reduced. Preferably, the error correcting code is superposed on the television signal during the vertical blanking period.

A method for producing a high-quality group-III element nitride crystal at a high crystal growth rate, and a group-III element nitride crystal are provided. The method includes the steps of placing a group-III element, an alkali metal, and a seed crystal of group-III element nitride in a crystal growth vessel, pressurizing and heating the crystal growth vessel in an atmosphere of nitrogen-containing gas, and causing the group-III element and nitrogen to react with each other in a melt of the group-III element, the alkali metal and the nitrogen so that a group-III element nitride crystal is grown using the seed crystal as a nucleus. A hydrocarbon having a boiling point higher than the melting point of the alkali metal is added before the pressurization and heating of the crystal growth vessel.
摘要:
An image forming apparatus is provided with a control section which stores detection results of a toner sensor regarding detection patterns. When forming a plurality of detection patterns on an intermediate transfer belt, the control section determines circumference-directional lengths of the detection patterns formed this time, based on the detection results of the toner sensor regarding the detection patterns formed immediately before. Thereby, the waste toner amount and toner consumption are not only decreased but also the time taken to detect the density of a detection pattern is reduced, while maintaining the detecting accuracy thereof.

Anisotropic rare earth-iron based resin bonded magnet comprises: [1] a continuous phase including: (1) a spherical Sm2Fe17N3 based magnetic material covered with epoxy oligomer where its average particle size is 1 to 10 μm, its average aspect ratio ARave is 0.8 or more, and mechanical milling is not applied after Sm—Fe alloy is nitrided; (2) a linear polymer with active hydrogen group reacting to the oligomer; and (3) additive; and [2] a discontinuous phase being an Nd2Fe14B based magnetic material coated with the epoxy oligomer where its average particle size is 50 to 150 μm, and its average aspect ratio ARave is 0.65 or more, further satisfying: [3] the air-gap ratio of a granular compound on the phases is 5% or less; and [4] a composition where crosslinking agent with 10 μm or less is adhered on the granular compound is formed at 50 MPa or less.
摘要:
When a group III nitride crystal is grown in a pressurized atmosphere of a nitrogen-containing gas from a melt 50 including at least a group III element, nitrogen and an alkali metal or an alkali earth metal, a melt-holding vessel 160 that holds the above-described melt 50 is swung about two axes different in direction from each other such as an x-axis and a Y-axis.
