Title: Image emphasizing system
Inventor: MORISHITA KOICHI
IPC: G06T1/00
Filed: 1986-04-25
Abstract: PURPOSE:To suppress pseudo-outline at edge parts emphasizing fine structure parts sufficiently by dividing a picture image into many partial images, extracting feature of every partial image and changing process of preparing a blurred picture image according to the feature. CONSTITUTION:A film input image 70 is digitized by a film reader 71 and taken in a process 72. The picture image is divided into many local areas of fixed size in the processor 72. Then, the difference between the center picture element and neighboring picture elements in the local area is calculated. Then, weight is calculated from the value of calculated difference, and a blurred image holding edges is obtained by calculation of a weighted average. Then, high frequency component is obtained by subtracting the blurred image from the value of the original image. The high frequency component is multiplied by emphasis coefficient. The original picture image is added to the result obtained and a final emphasized image is obtained. Above-mentioned process is executed on all picture element points. Such processing is made observing the image by a display 73, and the emphasized image is printed by a film writer 75.

Title: Self-hardening subgrade material
Inventor: OKADA TAKAHIKO
IPC: E01C3/00
Filed: 1998-03-24
Abstract: PROBLEM TO BE SOLVED: To obtain a self-hardening subgrade material early increasing the strength by constituting a burned product of a burned material or a coarsely crushed material thereof including a specified wt.% range of one or more kinds of C11 A7 CaCl2 , C11 A7 CaF2 , and C3 A. SOLUTION: A burned product made from one or more kinds of incineration ash of municipal refuse and incineration ash of sewage sludge and composed of 10-40 wt.% of one or more kinds of C11 A7 CaCl2 , C11 A7 CaF2 , and C3 A, and one or more kinds of C2 S, and C3 S is used as a subgrade material. Hereat, if aluminum compound is less than 10-40 wt.%, the incineration ash for aluminum source is in short supply and it is not favorable from the viewpoint of effective use of waste. If the compound exceeds 40 wt.%, an excessive expansion is sometimes brought because of accelerated hydration. It is not favorable too from the viewpoint of the design of a subgrade material.  Protection of natural resources such as sand or the like is advanced by selecting clinker for ecocement as a material for a subgrade and the burned product itself brings out early a self-hardening property and increases early the strength of a subgrade.

IPC: C01B3/38
Filed: 1993-04-22
Abstract: PURPOSE:To remarkably lower the heating temp. of a start-up heater or to start a gas reformer without heating by supplying a gas contg. H2 and CO2 or CO to a first reforming tube along with steam when the reformer is started. CONSTITUTION:A gaseous mixture of hydrocarbons and steam is primarily reformed, an oxygen-contg. gas is added to partially oxidize the reformed gas which is then secondarily reformed, and the obtained high-temp. gas is used as a heat source for the primary reforming reaction. When the gas reformer is started, a gaseous mixture of H2 and CO2, or CO is introduced from a passage 1 and steam from a passage 2 to bring about methanation reaction in the primary reforming tube 5, and the temp. in the tube 5 is raised. Consequently, a start-up heater 3 is greatly reduced in size, and the time until the O2-contg. gas is introduced is significantly reduced. Further, since the temp. of the tube 5 is raised, the tube 5 need not be heated by the gas from a secondary reforming part 8.
