Patent EP-0385498-A2 (EP)
Inventor: SHINKAI HIROYUKI
IPC: G11B7/125
Filed: 1990-03-02
Abstract: The present invention relates to an optical recording and reproducing apparatus comprising an erroneous recording prevention means which prevents this apparatus from making an erroneous recording or erasing operation while it records data on a writable disk (1). The apparatus is arranged such that, while it is performing a recording or erasing operation, a state of its beam of light just about to go off the control point of tracking and a state of its beam of light just about to go off the control point of focusing are each monitored and, when either of the states is detected, the recording or erasing operation is canceled. Hence, laser power of the beam of light can be controlled before the beam of light completely goes off the control point of tracking, thereby preventing the beam of light from affecting data having been recorded along other tracks.

Abstract: A computer system is disclosed in which different type of communication links are provided between different computers. A high speed data communication link between a personal computer (14) and a midrange computer (16) is disclosed. An application is run on the midrange computer, and simultaneously a different but related application is run on the PC. Then, the PC initiates a write command to write data from the PC to the midrange computer without prior direction from the midrange computer to initiate the write command. Next, the data is written into a buffer pool memory based on memory resident indicators whereby no channel program is required. This expedites the data transfer. The midrange computer application subsequently reads the data from the buffer pool memory. A master/slave relationship is also provided between the midrange computer and another computer or external device (13) for more controlled data communications.

Abstract: A method and apparatus are disclosed for the shaping of a sheet of preform material. A flat planar (heated) sheet of preform material is held tightly between two elastomeric sheets, the sheets and preform material forming a laminate assembly. The laminate assembly is then formed about a mold having the desired contours. The elastomeric sheets maintain the preform material parallel to the surface contours of the mold as the molding process proceeds. A fluid such as air is flowed between the mold surface and the laminate assembly during the forming process to prevent the elastomeric sheets from binding on the mold surface. Wrinkles are eliminated in the final shape of the preform material, and fiber distortion or tears or rips in the material are minimized due to the fluid lubrication between the mold surface and the laminate assembly.

Abstract: Alkaline earth metal alkylates having a spherical particle habit are prepared by dissolving an alkaline earth metal alkylate in a solvent, adding a second solvent which dissolves the alkaline earth metal alkylate only with difficulty or does not dissolve it at all, but which is homogeneously miscible with the solution of the alkaline earth metal alkylate in the first solvent, removing the first solvent and then removing the second solvent. The particle size can be controlled by means of the shear gradient during the precipitation or by the use of emulsion stabilizers. Emulsion stabilization leads to particles in the size range 0.5 to 20  mu m with a particularly narrow particle size distribution. Catalysts for polyolefin synthesis can be prepared on the basis of magnesium alkylates prepared by the process according to the invention. The polymer is advantageous with respect to particle habit and particle size distribution, compared with the prior art. A narrower particle size distribution, and thus a reduction in undesired oversize and undersized particles, and a smoother surface structure are achieved.
