Title: Liquid crystal display device and information device
Inventor: KATASE MAKOTO
IPC: G02F1/133
Filed: 1992-12-09
Abstract: PURPOSE:To enable obtaining a high definition screen with no cross talk even in high resolution display by applying driving voltage on the assumption that a limited current value is provided during a selecting period, in a matrix driving. CONSTITUTION:A large transient current is made to flow by switching a selecting period (tu) depending on characteristics of actual liquid crystal display devices, and voltage V0-V5 applied to liquid crystal elements is varied. Then, by applying driving voltage on the assumption that a limited current value is provided during a selecting period, an assumed effective voltage is applied to liquid crystal elements, and a driving waveform in which applied voltage to liquid crystal elements is zero is obtained at the time of switching of the selecting period. That is, the just same waveform as an assumed triangular wave can be applied to liquid crystal elements by controlling power supply voltage on the assumption that it is raised with some inclination. Therefore, there is no difference between a region of assumed voltage and a region of actual voltage, and cross talk does not occur.

Title: Magnetic card and recording and reproducing method thereof
Inventor: KISHIMOTO MIKIO
IPC: C09D175/00
Filed: 1989-12-20
Abstract: PURPOSE:To prevent the falsification of recording information and to improve the reliability at the time of recording information reading by providing a magnetic layer having the coercive force of a specific value or above as a signal recording layer and a magnetic layer having the coercive force of a specific value or below as a magnetic shielding layer on a substrate and specifying the surface roughness of the magnetic shielding layer to a specific value or below in terms of center line average height. CONSTITUTION:The coercive force of the signal recording layer is specified to >=700 oersted in such a manner that the recording information can be stably maintained against external magnetic fields. On the other hand, the coercive force of the magnetic shielding layer is required to be specified to <=100 oersted.the shielding effect is not sufficiently produced and there is the possibility of the leakage of the magnetic field from the signal recording layer to the outside if the coercive force exceeds 100 oersted. The magnetic shielding layer is formed to have the surface roughness of <=0.015 mum in center line average height. Namely, the quantity of the reflected light from the surface of the magnetic layer is not sufficient and the degradation in reproduced output is resulted if the surface roughness larger than this value is adopted. The falsification of the recording information is prevented in this way and the reliability at the time of reading of the recording information is improved.

Title: Transfer recording system
Inventor: SAWANO MITSURU
IPC: B41M5/40
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To minimize unrecordable parts to be generated due to adherence of dust or the like to the surface of a film between a toner film and a receiver film by furnishing a light absorption layer on the receiver film. SOLUTION: A toner 10 is laminated on the lower surface of a base 11 with a color agent layer 13 via a cushion layer 12. A receiver film 20 is formed by laminating a light absorption layer 23 on the upper surface of a base 21 via a cushion layer 22, and laminating heat adhesive layer on the upper surface thereof. Heat of the light absorption layer 23 by a laser beam from the upside acts to heat the heat adhesive layer 24. When color agent layer 13 is adhered on heated parts of the heat adhesive layer 24, images can be transfer formed desirably.  Upon heating the heat adhesive layer 24 through heat of the light absorption layer 23, since the light absorption layer 23 is set on the receiver film 20, a heat conductivity from the light absorption layer 23 to the heat adhesive layer 24 is hot precluded even in the event of dust or the like adhered to the surface of any film between the toner film 10 and the receiver film 20.

Title: Molded adsorbent and its manufacture
Inventor: MAEDA TAKESHI
IPC: B01J20/28
Filed: 1990-11-28
Abstract: PURPOSE:To obtain a molded adsorbent with a water filterability 100ml or less of heat-melting synthetic resin by junctioning activated carbon fiber at random with heat-melting synthetic resin at a mixing ratio of 100 parts for the former and one part or more to 5 parts or less for the latter and maintaining them in a junctioned state. CONSTITUTION:A slurry of uniform quality consisting of 100 parts of activated carbon fiber and one part or less to 5 parts or less of heat-melting synthetic resin with a water filterability of 100ml or less which can be beaten in pieces, is dehydrated and molded. Then the mold is heated so that the activated carbon fiber is junctioned at random with the heat-melting synthetic resin and is maintained in a junctioned state to obtain a molded adsorbent of paper structure. The molded adsorbent bent of paper structure is a material of such a structure that the activated carbon fiber which constitutes an adsorbent is arranged at random and finely like a thick Japanese paper. The heat-melting synthetic resin is such as polyacrylonitrile and no longer clogs the pores of activated carbon fiber, if it is filiform. To improve the strength of a molded product further, a non-heat melting fiber can be used as a reinforcing material.
