Title: Method for zeolitization from volcanic ash and glass, and continuous reaction device
Inventor: NITTA TAKASHI
IPC: C01B39/02
Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a method wherein glass and minerals including volcanic ash, which are blended or kneaded with an alkaline solution and previously heated, are irradiated with an electromagnetic wave so that zeolitization of the volcanic ash is accelerated, and thus its cation exchange capacity (anion exchange capacity) and its adsorption capacity are improved, and to provide an electromagnetic-irradiation continuous-reaction device. SOLUTION: The minimum amount of an alkali required for a reaction is made to penetrate into the particulate solid of a raw material by blending/kneading the glass (including a natural glass mineral) and the minerals including volcanic ash with an alkaline solution. The alkaline solution penetrating into the solid is irradiated with an electromagnetic wave and instantaneously cause the zeolitization reaction from the inner part of the particle by heat generation of the inner part of the volcanic- ash-mixed particle. A zeolitization method with a small discharging amount of waste alkaline water can be realized by adjusting the amount of the alkali and controlling the discharge of waste alkali not relating to the reaction.  When previously blending and adjusting vitreous particles (including a natural vitreous ingredient) with the raw material volcanic ash, a rapid zeolitization reaction (3-5 times faster than when not blending) can be made to occur by irradiation of the electromagnetic wave.

Filed: 2001-07-31
Abstract: PROBLEM TO BE SOLVED: To set a contrast threshold and an area threshold capable of minimizing the occurrence of overlooking and overdetection without having to preset a permissible variation value obtained by considering the scatter of non- defectives. SOLUTION: An operator designates local defective areas within a sample image, subsequently performs defect candidate detection with the area threshold as a minimum value (S2), and classifies the defect candidates into overlooked defects, noise defects and designated defect candidates (S3).

IPC: H04L47/80
Filed: 2001-08-07
Abstract: PROBLEM TO BE SOLVED: To perform smooth data transmission when it is impossible to ensure any communication rate corresponding to a communication service desired by a user due to the shortage of resources.

In this method, an indicator indicating the propriety of the adjustment of the communication rate is set in an RAB setting request to be transmitted form the switchboard to the base station controlling station, and only when the indicator indicates the validity of the adjustment of the communication rate, the base station controlling station decides the communication rate lower than the desired communication rate due to the shortage of resources, and transmits an RAB setting response including the decided communication rate to the switching station.

The 2nd exposure is set to, for example, 90% of the 1st exposure and then while a necessary margin is secured for the adjustment of the maximum exposure for other photosensitive materials, a decrease in block density can be minimized.  Further, the maximum density value corresponding to the maximum exposure is a reference density value whatever photosensitive material is used.
