Title: Organic medium functioning as optical disc
Inventor: YOSHIDA TAKUJI
IPC: G11B7/24024
Filed: 1988-08-08
Abstract: PURPOSE:To prevent an optical disc from oxidation and deterioration due to an effect of an air layer by pasting two sheets of org. medium formed by providing a reflection layer on a photochromic thin film by arranging each inside surface of each reflection layer to face each other. CONSTITUTION:A recording medium layer 12 comprising a compd. causing reversible change of extinction which is different for two kinds of light having different wavelength (e.g. two kinds of laser light) on a substrate 11, and a light reflecting layer 13 is formed on the layer 12 by the vapor-deposition of Al, etc. Then, obtd. two sheets of the optical disc are pasted together by arranging each layer 13 to the inside with an adhesive agent 14. Thus, the title medium is formed. Further, it is also preferred that a recording medium layer and a reflection layer are formed successively on a substrate, and that a rigid substrate is further pasted on the reflection layer for the formation of the medium. The repeatability for recording and erase are improved by forming the layer 13, and the prepn. is simplified since no spacer is inserted.

Title: Semiconductor device and its manufacture
Inventor: KAWASAKI YOJI
IPC: H01L29/78
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To suppress the leakage current caused by a secondary defect so as to make a p-n junction shallower by injecting a dopant into the main surface of a silicon substrate at a range longer than that of an impurity containing an element having such a property that prevents the solid-phase growth of silicon after the impurity is injected into the main surface of the substrate until an amorphous layer is formed. SOLUTION: An amorphous layer 1a is formed on the surface of a silicon single-crystal substrate 1 by implanting ions of an element, such as N<+> , C<+> , O<+> , Kr<+> , Ar<+> , He<+> , etc., having such a property that prevents the solid-phase grown of silicon into the substrate 1. Then a mask 5 is formed on the surface of the substrate 1 and an n- or p-type dopant is injected into the substrate 1 for forming a heavily doped active layer. The injecting energy of the dopant is set so that the range of the dopant can become longer than that of the injected impurity. Thereafter, the amorphous layer 1a is recrystallized through heat treatment.

IPC: G11B19/02
Filed: 1997-07-23
Abstract: PROBLEM TO BE SOLVED: To shorten a search time by performing a fine searching operation without closing a tracking control loop even after a coarse searching operation is completed and making the number of track traversing lines of the fine searching operation a value in which the number of lines counted in the coarse searching operation is subtracted from a specified number of lines to dispense with a pull-in time and an address reading time. SOLUTION: A controller 17 calculates a distance by comparing the address at the point of time of starting a rough search with the address of a search target point to specify it to a coarse search means 15. The coarse search means 15 moves an optical pickup to the track direction by driving a traverse mechanism 13. At the same time, the controller 17 outputs the number of target track traversing lines of a total searching operation to a subtracting means 32. Then, the controller counts the number of actrually traversed track lines while performing the coarse searching operation and absorbs the number of error lines of the coarse seaching operation by performing a fine search by the number of error lines between the number of coarse searching lines and the number of the target track traversing lines instantly at the time of completing the coarse search.

Title: Method for driving liquid crystal element
Inventor: HANIYU YUKIO
IPC: G02F1/133
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To display with analog gradation and high contrast without causing gradation deviation by driving a liquid crystal only in the range from a stable state of the liquid crystal when no voltage is applied to the state showing changes in brightness without domains. SOLUTION: The liquid crystal element is produced by holding a liquid crystal layer 18 between a pair of substrates 11, 12. A common electrode 16 is formed on the substrate 12 facing pixel electrodes 13. A referential voltage is applied on the common electrode 16. A voltage according to the information signal voltage is applied on the liquid crystal layer 18 to change the transmittance to display with gradation. The liquid crystal element is a chiral smectic liquid crystal element having one stable state when no voltage is applied. The chiral smectic liquid crystal element showing V-shape response characteristics causes changes in the brightness without domains and causes the changes in the brightness due to inversion of domains in the switching process depending on the voltage applied.  The driving conditions for the liquid crystal are determined by avoiding the range where the brightness changes due to the inversion of domains but in the range where the brightness changes without domains.
