Abstract: PURPOSE:To prevent a recording data from missing and lacking even in the case of a burst error and to reproduce the data at the real time by recording the occurrence of an error in an incidental data area when the error takes place at the time of recording. CONSTITUTION:At the time of recording, an input data Di is inputted to a signal processing part 7, and after processing an addition of an error correction data, etc., recording is performed in turn on a tape 2. Subsequently, it is reproduced by a reproducing head 5, and the presence of a burst error is detected by an error detecting circuit 8, and then the contents of a recording data, in which a recording error occurs, are stored by the processing part 7 in a memory 9 at a prescribed address, is recorded into subcode area at the succeeding write timing. At the time of reproducing, when a burst error is detected by the processing part 7 during reproducing data, the burst error data stored in the memory 9 is outputted via a change-over switch 11 for responsing to a changeover signal SW to a line L9. By this method, the recording data is prevented from missing and lacking, and the data can be reproduced at the real time.

Title: Fiber-reinforced ceramic and its production
Inventor: NAKAMURA TAKESHI
IPC: C04B35/80
Filed: 1997-10-09
Abstract: PROBLEM TO BE SOLVED: To obtain a ceramic having good toughness and good strength for a long time at high temperature by covering fibers with coating films in which inclusions are dispersed. SOLUTION: Fibers 2 are arranged in a ceramic matrix 1. The fibers 2 are covered with coating films 3. In the coating films 3, fine inclusions, namely particulate inclusions 4, whisker-like inclusions 5 and flaky inclusions 6 are dispersed. The matrix 1, the fibers 2, the coating films 3, and the inclusions 4-6 are produced from a ceramic such as a carbide (e.g. SiC), a nitride (e.g. SiN) or an oxide (e.g. ZrO). This method for forming the coating films 3 comprises adding the inclusions 4-6 to a polymer capable of being decomposed into the ceramic, such as a liquid polycarborane polymer, coating the surfaces of the fibers with the dispersion in a prescribed thickness and subsequently sintering the coated dispersion at 800-1800 deg.C. The sintering temperature is higher than the use temperature of the ceramic. The inclusions desirably have sizes of 0.1 μm to several ten μm.  The sizes prevents the development of cracks 7. The thickness of the coating films is 0.5 μm to several tens tens μm.

Title: Display device
Inventor: TANIGUCHI NAOSATO
IPC: G02F1/37
Filed: 1988-11-02
Abstract: PURPOSE:To make an observation without any color blurring while reducing the size of the whole device by using a nonlinear optical element which generates a high frequency in the visible-light range and a luminous flux coupling element such as a hologram. CONSTITUTION:Laser light of wavelength lambda1 from a laser 1 is scanned by an optical deflector 2 in two dimensions and made incident on the nonlinear optical element 3. The nonlinear optical element 3 converts the incident coherent light of wavelength lambda1 into luminous flux of wavelength lambda2 and thus the nonlinear optical element 3 generates the scattered light which is wavelength-converted to the wavelength lambda2, thereby displaying display information 4. Then luminous flux based upon the display information 4 generated by the nonlinear optical element 3 is incident on the hologram 5. The hologram 5 has such optical characteristics that a display body 8 in an external field and display information 4' which is converted into the scattered luminous flux of wavelength lambda2 are observed spatially one over the other. Consequently, while the whole device is reduced in size, the observation is made in a state wherein there is no color blurring and the contrast is high.
