Title: Fireproof three-layer pipe
Inventor: WATANABE RIKUO
IPC: F16L9/12
Filed: 2000-04-10
Abstract: PROBLEM TO BE SOLVED: To have a superior fire resistant synthetic resin pipe. SOLUTION: When this fireproof three-layer pipe 10 is heated to a prescribed temperature or more by flames in a fire, a glass frit 16a in an intermediate layer 16 is melted. When the temperature increases further, the molten glass frit 16a and the synthetic resin are expanded while combined together and solidified to form a fireproof layer 74. The fireproof layer 74 is incombustible so as to be prevented from burning further by an external fire. Therefore, fire and smoke do not pass through the pipe.

Title: Synthesis confirming method and hydroxyapatite
Inventor: ISHIKAWA TAKESHI
IPC: C01B25/32
Filed: 2000-04-12
Abstract: PROBLEM TO BE SOLVED: To grasp a degree of progress of the synthesis of a desired synthesized material highly accurately and highly sensitively with a simple method. SOLUTION: This synthesis confirming method is a method for confirming a degree of progress of the synthesis when hydroxyapatite as the desired synthesized material is synthesized, for example from a first raw material such as calcium hydroxide and a second raw material such as phosphoric acid. The sample including hydroxyapatite is taken out and formed in a prescribed shape, subsequently the formed body 1 is calcined and the plate-like sintered body 2 is irradiated with light emitted from a light source 3. By examining the color of transmitted light, the degree of progress of the synthesis of hydroxyapatite is confirmed.

Title: Digital camera, image processor, image processing method and recording medium
Inventor: UCHINO FUMIKO
IPC: H04N5/335
Filed: 2000-04-13
Abstract: PROBLEM TO BE SOLVED: To provide a digital camera which can perform switching between the spot light reading and the multi-division light reading and then corrects properly an image according to the light reading system. SOLUTION: This digital camera includes a correction method deciding part 321 to decide the light reading system of a light reading part 27.

Title: Method for banding outlet of container bag
Inventor: SHIOTANI SHINTARO
IPC: B65D88/22
Filed: 2000-04-13
Abstract: PROBLEM TO BE SOLVED: To easily untie a knot with a reduced production cost of a banding adjuster. SOLUTION: An outward form of an adjuster body 281 is a rotational symmetric form wherein an outward dimension W in a direction orthogonal to a through direction reduces as coming toward both ends of the through direction of a through hole 282. Since a region in contact with a knot L of a rope 260 of the adjuster body 281 is thus a curved surface, a contact area between the rope 260 and the body 281 at the knot L is reduced, and therefore the knot L can be easily untied. In addition, since tightness of the knot L is mainly determined by easiness in sliding between the rope 260 and the body 281, it is little affected by the form and dimension of the adjuster body 281. Therefore, it is not necessary to strictly manage the form and dimension of the adjuster body 281 for every thickness and type of the rope 260.

IPC: G02F1/1368
Filed: 2000-04-20
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display element having a high aperture ratio and high response speed without heightening the total driving voltage. SOLUTION: In the liquid crystal display element having a display system in which display is performed by applying an electric field to a liquid crystal interposed between substrates in a direction nearly parallel to a surface of the substrate by using electrodes 101 and 102 provided on the substrate, the electric field is specified to be applied to the liquid crystal in a partial region of each pixel more intensely than to the liquid crystal in the other region. Since the response speed of a portion of the liquid crystal in the pixel is made high, the response of the other portion of the liquid crystal also follows it and the response of the liquid crystal in the total pixel is also made high. And since the electrodes are disposed so that the electric field is applied more intensely to only a part of the pixel, the aperture ratio is not reduced.
