Title: Liquid crystal device
Inventor: SATO KOICHI
IPC: G02F1/141
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal device, having V-shape response characteristics with high reliability in which good gradation display is possible and deterioration in the alignment with time or burning is prevented by controlling the temperature width, where both phases of an isotropic phase and a smectic A phase of a chiral smectic liquid crystal composition are present as mixed to a specified value or smaller in the transition process from the isotropic phase to the smectic A-phase. SOLUTION: In the liquid crystal device, a chiral smectic liquid crystal composition containing two or more components of compounds and having a phase transition system which transists from an isotropic phase to a smectic A phase is used, and the device has V-shape response characteristics. In the transition process of the liquid crystal in the device from the isotropic phase to the smectic A phase, the temperature width where both phases are present (I-A mixture temperature range) is specified to be 3.5 deg.C or lower. By decreasing the I-A mixture temperature range in the device is to 3.5 deg.C or lower, switching abnormality of the liquid crystal device having V-shape response characteristics can be improved. As for the liquid crystal composition having a larger number of components, the I-A mixture temperature width is preferably decreased further.

Title: Liquid crystal injecting device and method therefor
Inventor: JEONG SEONG-WOOK
IPC: G02F1/1341
Filed: 1998-07-13
Abstract: PROBLEM TO BE SOLVED: To make it possible to reduce the consumption of liquid crystals in the injection process of the liquid crystals by injecting the liquid crystals contained in a vessel by using capillarity. SOLUTION: The liquid crystals 4 contained in the vessel 10 are injected by using the capillarity. The vessel 10 of this device is a rectangular parallelepiped bored with a notch having a difference in level and is formed with the difference in level between the inner bottom surface and inner flank of the vessel 10. The bottom surface of the vessel 10 enclosed by this difference in level allows the fitting of the bottom surface of a base 20 and plays the role of fixing this base 20. In the case the liquid crystals 4 are injected by using this device, the liquid crystals 4 are poured into the vessel 10 on which the base 20 is placed and fixed. The amt. of the liquid crystals 4 to be poured into the vessel 10 is confined to, for example, <=10 cc.  If the liquid crystals are injected in such a manner, the liquid crystals 4 contained in the vessel 10 move to the upper surface by passing the slender grooves disposed on the flanks of the base 20 and accumulate at the point where the grooves intersect. The accumulated liquid crystals 4 have the shape projected to the upper side by surface tension and the liquid crystals 4 at the respective intersection points are gathered and are uniformly distributed on the upper surface.

IPC: H01S3/17
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an optical fiber, enabling to suppress the generation of Rayleigh scattered light to reduce beat noises. SOLUTION: This method for producing an optical fiber has characteristics comprising adding an additive (e.g. germanium oxide) for enhancing the refractive index of the core of the optical fiber on the basis of the clad and further adding other additives (e.g. aluminum trioxide and erbium) for forming an inverted population due to exciting light in the core. Therein, the addition amounts of the additive and the other additives are set on the relation of an absorption loss per unit length of light transmitting in the core to a specific refractive index difference between the clad and the core, when the refractive index of light transmitting in the core is set to a preliminarily set value (e.g. -48dB) or less.

Abstract: PROBLEM TO BE SOLVED: To provide a new image communication equipment capable of the partial magnification display of images on a reception side while background images are kept being sent without inviting the increase of a transmission capacity. SOLUTION: This equipment is provided with a camera 3 for photographing the background images within a specified view field, converting them to image signals and outputting them, an area specifying means 5 for coordinate-specifying an optional area within the specified view field, a transmission line 7 for transmitting at least the image signals, an extraction means 10 for extracting the images of the area from the image signals in the case that the area is specified by the area specifying means 5, an image magnifying means 11 for performing the magnification processing of the images extracted by the extraction means 10 and a display means 13 for displaying the image signals transmitted by the transmission line 7 and the images magnified by the image magnifying means 11.  Since it is sufficient that the transmission line 7 transmits only the coordinate information of the optional area in addition to the image signals to the maximum and the coordinate information is far less capacity compared to image information, the substantial increase of the transmission capacity is not invited.
