Title: Liquid crystal display device
Inventor: HIRASAWA YUKINORI
IPC: G02F1/1333
Filed: 1992-06-22
Abstract: PURPOSE:To prevent generation of deterioration of an image quality such as uneven luminance and uneven contrast, etc., due to a fact that a liquid crystal material is heated by heat of a light source by positioning a first and a second polarizing plates so as to pinch a display body and a cooling part being close to each other. CONSTITUTION:This display device is provided with a display body 1 having a liquid crystal layer containing a liquid crystal, a cooling part 2 which is provided closely to this display body 1, and has a cooling layer containing a refrigerant, and a first polarizing plate 3 and a second polarizing plate 6. Also, a first polarizing plate 3 and a second polarizing plate 6 are positioned so as to pinch the display body 1 and the cooling part 2 being close to each other. Accordingly, since there is no polarization between the cooling part 2 and the liquid crystal display body 1, the cooling part 2 can cool efficiently the liquid crystal, and also, one of the polarizing plates which are apt to generate heat can be separated from the liquid crystal display body 1, the liquid crystal display body 1 is scarcely overheated.

Title: Magnetic reproducing method
Inventor: KUMANO KATSUFUMI
IPC: G11B5/02
Filed: 1986-08-07
Abstract: PURPOSE:To reproduce information with a high resolution and a good S/N by impressing an AC magnetic field to a recording medium and detecting the magnetization polarization induced in a magnetization boundary area to reproduce information. CONSTITUTION:When the AC magnetic field is impressed to a recording medium 1 by a magnetic head 4 around which a coil 3 connected to an AC power source 2 is wound, the magnetization polarization is induced in a magnetization boundary area C by the difference of AC permeability because a magnetization vector is relatively easily shaked to increase the AC permeability in the magnetization boundary area C. This magnetization polarization is detected by a detecting coil 6 of a detecting head 5, and the detection signal is processed by a signal processing circuit 7 to reproduce recorded information on the recording medium 1. Thus, information on the recording medium 1 is reproduced with a high resolution and a high S/N even if this recording medium 1 has a high recording density.
