Title: Magneto-optical recording medium and recording and reproducing method therefor
Inventor: KAWANO TOSHIFUMI
IPC: G11B11/105
Filed: 1993-08-06
Abstract: PURPOSE:To provide a medium with which a super resolution effect is obtainable without using a reproduced magnetic field by decreasing the Kerr rotating angle of a mask part of an FAD medium and the recording and reproducing method. CONSTITUTION:A reproducing layer 3 consisting of Gd30(Fe80Co20)70 (numerical values are atomic %), a cut layer 4 consisting of Tb20Fe30 and a recording layer 5 consisting of Tb21(Fe80 Co20) are laminated via a Ta2O5 thin film on a light transmittable polycarbonate substrate. The Curie temps. of the respective layers are maintained at a prescribed relation. The magnetic layer 3 has the exchange bonding strength enough for the entire magnetization to be in the direction perpendicular to the substrate surface at >=25 deg.C and a temp. sufficiently lower than the curie temp. of the cut layer 4. The exchange bonding strength of the recording layer 5 and the reproducing layer 3 decreases or dissipates at a temp. near the Curie temp. In addition, the magnetization direction of the reproducing layer inclines in a direction parallel with the substrate plane. Oxidized protective films of SiO2 are formed on both sides of the magnetic layer. The lands 2 between the grooves 1 of the medium are irradiated with light and a regenerating beam spot 6 is partly heated, by which a high-temp. region 9 is created. The magnetization direction is made parallel with the substrate plane and the Kerr rotating angle is drastically degraded.

Title: Liquid crystal element
Inventor: KANEMOTO AKIHIKO
IPC: G02F1/133
Filed: 1986-08-22
Abstract: PURPOSE:To obtain a liquid crystal element, on which an orientation treatment can surely be performed and which has a stable memorizability by providing an orientation film in which molecules are almost oriented on a base plate and preventing adhesion of dust to the base plate. CONSTITUTION:Ferroelectric liquid crystal is held between base plates 11 and 21 facing each other and orientation films 15 and 25, in which molecules themselves constituting the films are almost oriented, are provided on, at least, the surface of one-side base plate. Then the molecules of the liquid crystal are oriented horizontally against the surfaces of the base plates. For example, a single molecule layer formed by using Langmuir Blodgett's method, film formed by piling up single molecule layers, or film which is composed mainly of high-molecule liquid crystal can be used as the oriented film. It is especially desirable to use a single molecule layer or film formed by piling up single molecule layers of polyimide as the orientation film. The number of the piled-up layers is, desirably, 1-500. When such orientation film is used, no rubbing process is required and, accordingly, adhesion of dust can be prevented and a memory-like property can be exerted.

Title: Electrostatic charge preventive method and humidifier for same
Inventor: OBATA ZENSHI
IPC: H05F1/00
Filed: 1990-07-27
Abstract: PURPOSE:To prevent static electricity generated on an object transported and maintain the specified feeding speed by supplying a humidified air bubble generated in a water trough into the space for transportation, and varying the humidity around the object. CONSTITUTION:An air pump 11 is operated, and bubbles are produced in the water by a bubble generator 4, and now the humidity of the air in a humidifying chamber 6 is raised gradually. From a fan 5 the external air is supplied to this humidifying chamber 6, the humidity of the air is adjusted properly, and the humidified air with the humidity adjusted is flowed into the space for transportation 9 via a duct 7 by the wind pressure of the fan 5. Accordingly only the humidity of the space 9, i.e., humidity around the object transported, rises locally even though the humidity in the working room is maintained to a specified level. This prevents generation of static electricity, and the feeding speed of a supplying machine 8 can be kept at a specified value.

IPC: G09G5/393
Filed: 1991-08-07
Abstract: PURPOSE:To shorten the rewrite time of display data during a display period. CONSTITUTION:A timing generating part 12' outputs a control signal SCI consisting of a row address strobe signal bar RAS1, a column address strobe signal bar CAS1, and a write control signal bar WE1 to the control input C of a DRAM 31, and also, outputs a control signal SC2 consisting of a row address strobe signal bar RAS2, a column address strobe signal bar CAS2, and a write control signal bar WE2 to the control input C of a DRAM 32. The control signals SC1 and SC2 are the signals independent from each other generated based on the least significant bit LSB of an internal address MA. Since the readout operation of the display data can be performed independently in every storage part (DRAM), it is possible to shorten the readout time of the display data as a whole, and since the write operation of the display data can be performed in the display period for a long time by that share, the rewrite time of the display data can be shortened.

The comparator 7 judges the result of the comparison, and, if epsilon<=E, informs a controlling circuit 1 of the result. Upon receiving the information, the circuit 1 repeats the above mentioned control on the next point n+1. When the circuit 7 judges that epsilon>E, it judges that a point row F cannot be approximated by a point string G. When all the calculations on (n) pieces are completed at the circuit 3 and the above mentioned operations are completed, it is judges that the point string F can be approximated by the point string G.
