Title: Method for estimating phosphorus concentration in molten steel
Inventor: OGAWA YASUNORI
IPC: C21C5/46
Filed: 1993-03-23
Abstract: PURPOSE:To precisely measure phosphorus concn. in molten steel at the time of executing steelmaking operation, in consideration of variation in slag formation degree following the charge of a slag forming agent. CONSTITUTION:At the time of blowing in the steelmaking operation in a converter, the phosphorus concn. in the molten steel in functionalized with a time (t) from start of the blowing, melting quantity of the slag forming agent at this time (t) and melting quantity of CaO at this time (t), equipment condition and operational condition and molten iron information. The estimated value of the melting quantity of CaO is corrected every time (t) based on an assumption that the melting of CaO is promoted as the melting quantity of the slug is increased. Based on these corrected estimated values of the melting quantity of CaO, the phosphorus concns. in the molten steel are estimated. By this method, the phosphorus concn. is surely estimated at intervals from the start of blowing to the completion of blowing.

Title: Data transmitter
Inventor: HAYASHI MASAHIKO
IPC: H04M3/58
Filed: 1993-03-01
Abstract: PURPOSE:To automatically identify a case that a call back is operated from the case that data communication is operated without operating the call back without registration and management of a large amount of telephone number at a reception side for the call back operation. CONSTITUTION:After an automatic incoming call, a telephone number information receiving function part 11 receives the telephone number information from a transmission side, and temporarily stores it. After line disconnection, a call back control part 13 operates the call back by using the telephone number. Therefore, the registration and management of the telephone number is not necessitated at the reception side. Also, only when the telephone number information is received, and a call back request is received within a fixed time after the automatic incoming call, the call back is operated. Thus, when the call back is not necessitated, normal data communicating state can be automatically obtained.

Filed: 1986-03-25
Abstract: PURPOSE:To improve the structure of a magnetic shield wall, and realize a source saving and a lightweight, by forming a magnetic shield mainly of a highly permeable powder agent directly at the outside of a vacuum envelope. CONSTITUTION:At the necessary portions of a glass vacuum envelope 25, a mixture of a high permeability powder agent and a binder is spread and dried. It is spread and formed into a membrane 1 at a necessary thickness at the portions of the envelope to get a magnetic shield function. For this purpose, it is spread thicker at the input side and thinner at the output side. By applying a metallic powder such as a permalloy in such a way, it acts as a conductive membrane, as well as it is effective to reject the charge at the vacuum envelope. Therefore, the magnetic shield wall of a high permeability can be minimized irreducibly and formed with a small amount of source while the handling is made easy.

Abstract: PURPOSE:To acquire an element formation layer of a fixed concentration of impurities by providing a process to introduce impurities to an Si substrate at the side for forming an element formation layer before processes such as formation of an insulating layer and lamination. CONSTITUTION:Impurities of a fixed concentration are introduced to a first Si substrate 1 whose surface is adequately smoothened by ion implantation. Thereafter, an insulating layer 2 is formed.

Heat treatment is carried out to reinforce the junction. By carrying out heat treatment, an impurity concentration inside an element formation layer 4 acquired through a following process can be made almost fixed regardless of dispersions in film thickness of the layer 4. Then, polishing, etc., is carried out from a rear side of the substrate 1 to remove the substrate 1 leaving the layer 4. According to the processes, it is possible to acquire uniform characteristics of an element even when a film thickness of the layer 4 is irregular inside the substrate 3.

IPC: F24H1/18
Filed: 1986-03-25
Abstract: PURPOSE:To make it possible to display the amount of hot water in an analog manner, by providing a shape memory alloy spiral within a hot water storage tank. CONSTITUTION:Scales 0-50 with a unit of 1l are formed on the side of a glass window 2 of a hot water storage tank 1.
