Title: Information glass substrate and its production
Inventor: MATSUDAIRA TAKAO
IPC: G11B7/2433
Filed: 1984-04-25
Abstract: PURPOSE:To enable formation of a rugged information layer having high uniformity by forming silicon nitride on one main plane of a glass substrate and subjecting said nitride to dry etching. CONSTITUTION:The silicon nitride layer 2 and photoresist 3 are formed on the disk-shaped soda lime glass substrate 1. Laser light is irradiated according to an information signal to said substrate 1 while the substrate is rotating to form a resist pattern 4. The layer 2 is subjected to plasma etching with the pattern 4 as a mask by which ruggedness is formed thereon and an information layer 5 is thus formed. The sodium ions from the substrate 1 do not diffuse into the silicon nitride 2 unlike silicon oxide and therefore the formation of the exact ruggedness meeting the pattern 4 with good reproducibility is made possible.

Title: Monitoring and control apparatus of hydro-electric power station
IPC: G01M99/00
Filed: 1992-04-06
Abstract: PURPOSE:To detect an abnormality at an early stage and to perform the preventive maintenance of a trouble by a method wherein process data by means of artificial intelligence are accumulated at a slave station, the abnormality is monitored and the occurrence of the abnormality is estimated as well as the accumulated data and the result of a monitoring operation are transmitted to a master station. CONSTITUTION:A slave station 1 accumulates plant data which have been taken into; it transmits them to a master station 2 periodically. Operating results (outputs, voltages, dam water levels, trouble items) and related data may be enumerated as the data to be transmitted. At the master station 2, the data on the operating results are processed every day/week/month, and the operating results are compared with a plan. At this time, since huge amounts of data such as apparatus temperatures, vibrations and the like are not transmitted, items to be processed at the master station 2 are simplified. When an accident is caused, the master station 2 makes a request to the slave station for required operating data, and investigates its cause by means of the data. At this time, the cause can be inferred by taking into consederation the data accumulated at the slave station 1 and a change in the efficiency of a waterwheel, which could not be grasped in conventional cases. As a result, the cause can be analyzed easily and accurately.

Title: Production of bisphenol a
Inventor: ISHII TERUHIKO
IPC: C07C39/16
Filed: 1990-03-30
Abstract: PURPOSE:To obtain a highly pure bisphenol A crystal in a high yield by reacting phenol with acetone in the presence of an acid catalyst, crystallizing, separating the reaction product, subjecting the remained mother solution to a purification process accompanied with the cleavage reactions of by-products to remove the impurities, and subsequently recycling the remained products. CONSTITUTION:Phenol is reacted with acetone in the presence of an acid catalyst and water and the catalyst are removed from the reaction solution containing crude bisphenol A. The solution is concentrated, cooled and subjected to a crystallization process and then to a solid-liquid separation process. Furthermore phenol contained in the solid phase portion is removed to obtain highly pure bisphenol A. The remained mother solution is concentrated, cooled and subsequently subjected to a solid-liquid separation process. The solid phase portion is mixed with the crude bisphenol A and recycled. The liquid phase portion is subjected to a cleavage reaction in the presence of an alkali catalyst to remove most of the reaction by-products. The reaction solution is subjected to a recombination reaction and subsequently recycled into the reaction system. The method does not cause the recyclization and accumulation of the impurities, minimizes the contamination of the processes and provides the slightly colored bisphenol A having a high quality.
