Abstract: PURPOSE:To widen a playback frequency range by press-forming by compressed air an urethane foam which has the thinnest thickness and large density at the top of the truncated-cone shape and the thickest thickness and small density at the circumferential part. CONSTITUTION:Diaphragm base material 3 in a truncated-cone shape is roughly formed and placed on base mold 1 being mounted on a rough net. An indirect contact object with air-impermeable synthetic-resin film 8 stuck on the top surface of  urethane foam 7 which has the thinnest thickness and large density at the top of the truncated-cone shape and the thickest thickness and small density at the circumference while varying in thickness and density gradually from the top to the circumference is fitted to upper mold 4 and compressed air is supplied to chamber 9 provided inside of upper mold 4 to press urethane foam 7 against diaphragm base material 3. As a result, it is pressed hardly near the top of base material 3 and slightly  near the external circumference.

Title: Method for detecting abnormality of earth line of ac electric arc furnace
Inventor: TAMAKI MASAKATSU
IPC: F27D11/08
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of serious fault or failure by providing two furnace shell earth lines of an AC electric arc furnace, measuring a current being induced in the earth line during operation of the arc furnace and delivering an abnormality signal when the measured current exceeds a set current level by a specified amount or more. SOLUTION: In addition to an existing earth line 4, a furnace shell 3 is connected with an earth line 5 connected with another earth electrode to form a loop through the earth. The earth line 5 is connected with an ammeter 6 for measuring a current being induced in the earth line 5 during operation of an AC electric arc furnace. A measurement signal is transmitted to a current level comparing circuit and an abnormality signal is generated if (set current level - measured current level) exhibits a level above 0 when the set current level is set at 25 A while taking account of a minimum measurement level of 50 A. Since an abnormality, e.g. breakage of the earth line, can be detected instantaneously during operation, serious fault, e.g. melting of refractory, can be prevented.

IPC: B41J2/35
Filed: 1986-01-13
Abstract: PURPOSE:To attain to enhance not only the efficiency of printing energy but also printing quality and to prolong the life of a head, by performing printing by heating a transfer film or thermal paper by a high frequency magnetic field generating means. CONSTITUTION:A high frequency current is supplied to the coil 3 wound around a magnetic body 4 from a high frequency power source 1 by a switching circuit 2. A high frequency magnetic field passes through the magnetic body 4 and is ready to avoid the passage through the gap 5 interposed in the magnetic body and, therefore, issues to the outside to pass through a transfer film 6. The high frequency magnetic field allows an eddy current to flow through the transfer film 6 being conductive to generate Joule heat and ink is melted by said heat to be transferred to printing paper 7. As a result, printing heat is efficiently transferred to thermal paper or the transfer film and no adverse effect due to the accumulation heat of a head is exerted on printing quality and, when a plurality of dots are constituted, no adverse effect is exerted between adjacent dots.
