IPC: E04C2/30
Filed: 2000-08-21
Abstract: PROBLEM TO BE SOLVED: To develop a ceiling board with excellent heat insulating property.

Filed: 2000-09-13
Abstract: PROBLEM TO BE SOLVED: To solve the problem that the magnetic domain transfer from a recording layer to a reproduction layer can hardly be controlled due to unstable mask formation in the reproduction layer unless proper thermal control is performed in a non-magnetic intermediate layer, since the mask formation is largely affected by the temperature distribution of the reproduction layer and the thermal control of the non-magnetic layer largely affects the temperature distribution though it is necessary to form the proper mask in magnetic domain transfer from the recording layer to the reproduction layer for obtaining high resolution because thermal control is difficult in the non- magnetic intermediate layer as a magneto-optical recording medium has a multi-layer structure in a magnetic super resolution technique and a magnetic domain extending/ reproduction technique. SOLUTION: In the magneto-optical recording medium, which is provided with a recording layer where information is recorded on a substrate and performs at least one of the recording or reproducing of information by being irradiated with light, a non-magnetic thermal conductive intermediate layer of >=20Wm-1K-1 thermal conductivity is laminated at the light incident side of the recording layer, and the reproduction layer is laminated at the light incident side from a conductive intermediate layer, thus a magnetic domain transferred from the recording layer is extended and reproduced.

Filed: 2000-09-11
Abstract: PROBLEM TO BE SOLVED: To enable highly reliable header detection in the case of reproducing a DVD-RAM. SOLUTION: With a level, which applies the offset of a prescribed level to integrating outputting integrating a push-pull signal, as a threshold, a header area is detected by comparing this threshold with the push-pull signal.

Title: Active matrix type display device
Inventor: MIYAJIMA KOJI
IPC: G02F1/133
Filed: 2000-09-18
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption of an active matrix type display device, and also to highly integrate the circuit thereof. SOLUTION: A holding circuit 110 for holding a video signal is arranged for each pixel, and the video signal is displayed by switching between a normal operation mode and a memory operation mode. By arranging the holding circuit 110 to be superimposed on a pixel electrode 17, and superimposing adjacent pixels on the circuit, a space factor of the circuit arrangement is improved and the circuit area of the holding circuit 110 is reduced. Especially, in a reflection type LCD, the arrangement of superimposing the holding circuit 110 on a reflecting display electrode 17 does not cause a decrease in an opening ratio due to the holding circuit, and the reflection type LCD can be made to be a display device of a higher opening ratio. Superposition of the holding circuit by two adjacent pixels makes it possible to arrange the circuit to be point- symmetric, and improves a design effect.  Superposition of three adjacent pixels improves the space factor further.
