Abstract: PURPOSE:To smoothly send a material to be treated to the discharge side of a drum while keeping the material to not stick to a screw, by allowing a scraper having a specific structure to rotate to the same direction by synchronizing with the screw. CONSTITUTION:A material to be treated which exists between the blades 5a of a screw 5 is inhibited from being rotated together with the screw 5 by means of a scraping body 6b because the scraping body 6b of a scraper 6 is inserted between the blades 5a of the screw 5. Further the scraping body 6b of the scraper 6 is made spiral at the same lead angle as the blades 5a of the screw 5, and also rotated synchronously with the screw 5 and therefore can be inserted between the blades 5a without interfering with the blades 5a. Further since the scraper 6 and screw 5 are rotated to the same direction, both are mutually turned to the directions passing by each other in the crossing parts of the scraping body 6b and the blades 5a, and scraping effect of the material to be treated is made large with the scraping body 6b.

Filed: 1989-06-30
Abstract: PURPOSE:To obtain light emitting characteristics of quantum fine wires by forming the 1st barrier layer, quantum well layers, and the 2nd barrier layer on a III-V compound semiconductor substrate which is stepped off from each prescribed surface by specific angle and then, forming each III-V compound semiconductor containing (In) by one atomic layer or less during the formation of quantum well layers. CONSTITUTION:The 1st barrier layer is formed on a III-V compound semiconductor substrate which is stepped off from a plane (h k l) by an angle theta (rad). Further, quantum well layers are formed on the above barrier layer. Then, the 2nd barrier layer is formed on the above quantum well layers and then, each III-V compound semiconductor containing (In) is formed by one atomic layer or less during the formation of the quantum well layers. Each quantum well layer is composed of III-V compound semiconductors; besides, the (h), (k), and (l) is an integer respectively which satisfies expressions: h<=1, k<=1, l<=1. (theta) is determined so that it may satisfy an inequality: a/600<=theta<=a/40 with respect to a lattice constant a (Angstrom ). Intervals between single atomic layer steps determines the length of a period time in lateral quantum well structure. In the cases of normal III-V compound semiconductors (GaAs, InP, and the like), as the intervals are liable to be within 20-300Angstrom , the intervals even in the single atomic layer steps are required to be spaced to such an extent as mentioned above.

Abstract: PURPOSE: To foresee and prevent the surface cracking of an ingot during continuous casting, the  breakdown of a solidified shell, etc. by densely providing temp. detecting elements in the width  direction of a continuous casting mold, and detecting the deviation of the casting temp. from a  steady level to lower or higher temperature level side.   
     CONSTITUTION: Temp. measuring elements (thermocouples) are disposed densely in a width  direction to the approximate center position in the longitudinal direction of the long side mold  plates 1 of the above-mentioned molds. Of these thermcouples, the adjacent, for example, three  thermocouples are defined as A, B, C, and now if it is assumed that a longitudinal crack occurs in  the position B in the width direction in the mold, the mold temp. in the part B or the part including the surrounding thereof is lowered, so that the output fluctuations of the thermocouple at B  deviate from a steady level to lower temp. side like the point P. on the other hand, if parts 4, 5 of  the solidified shells stick on the mold side and assume the state that they are off-boarded from the  ingot side shell, the gap point (y) deviates to the higher temp. side, hence it can foreseen that  breakout will occur in the ingot emerged from the bottom end of the mold. Here, 2 in the figure  denotes the short side mold plates and 6 the molten steel, respectively.

Title: Consciousness detecting device
Inventor: MITANI HISASHI
IPC: A61B5/00
Filed: 1989-06-30
Abstract: PURPOSE:To effectively deal with the swoons and consciousness reduction of a pilot by outputting a blood flow deficiency signal with a blood flow judging means when the size of the downward acceleration G applied to the pilot exceeds the preset value. CONSTITUTION:When the blood flow reaches to a dangerous level by the action of the excessive downward acceleration G and a pilot A swoons as a result, a blood flow deficiency signal S1 and an acceleration excess signal S2 are outputted to an AND circuit 7 from an output judging unit 3 and a G judging unit 6, respectively, and the AND circuit 7 outputs a consciousness loss signal S3 to an automatic pilot 8 for automatic steering. A crash accident or the like can be effectively prevented. No consciousness loss signal S3 is outputted unless the acceleration excess signal S2 is outputted even if the blood flow deficiency signal S1 is outputted, thus the automatic pilot 8 is not easily operated by the noise or the like of the blood flow sensor 1, and the reliability of a system is improved.
