Title: Manufacture of oxide superconductive ceramic wire rod
Inventor: YAMADA YUTAKA
IPC: C01G1/00
Filed: 1988-12-12
Abstract: PURPOSE:To prevent the deterioration of superconductive characteristics of a wire rod by adding a specified amount of Ag2O in a superconductive ceramics. CONSTITUTION:When a superconductive ceramics 2 having 5-30wt.% of Ag2O added thereto is charged in a sheath 1 such as Ag to form a wire rod, the oxygen loss amount of the superconductive ceramics is reduced due to the O2 gas generated by the thermal decomposition of Ag2O at the time of heat treatment. At a result, the deterioration of superconductive characteristics of an oxide superconductive ceramic wire rod is prevented. When Ag2O is charged in the center part of the ceramics without using the Ag2O mixture, the same result can be obtained.

Title: Rotary heating curing device for frp molded body
Inventor: ISHIIDE HIDENORI
IPC: B29K105/08
Filed: 1989-11-30
Abstract: PURPOSE:To prevent generation of run-out and to obtain excellent straightness by forming a mandrel of magnetic substance and on the other hand, equipping a magnetic force generating member which is provided adjacently to the mandrel in the nearly central part thereof and reduces deflection of the mandrel by magnetic force. CONSTITUTION:A magnetic force generating member 7 may be ordinarily arranged in accordance with the nearly central position becoming the centroidal position of a mandrel 6. For example, when the inner diameter of an FRP molded body 5 is made to a tapered line, the centroidal position of the mandrel 6 is separated from the center. Therefore it is necessary that the magnetic force generating member 7 is moved in accordance with the centroidal position. Accordingly when a column 17 fitted with the member 7 is movably provided on a trestle 4, e.g. provided so as to be ridden on a guide rail, the member 7 easily corresponds even to the mandrel 6 different in the centroidal position. The range of application object of a device 1 can be spread. In such a way, a deflection generated in the mandrel 6 under rotating is reduced by arranging the member 7 adjacently to the nearly central part of the mandrel 6 formed of the magnetic substance. An FRP molded body 5 having excellent straightness can be obtained.

Title: Recording and reproducing device
Inventor: SATO TETSUYA
IPC: G11B5/027
Filed: 1987-12-10
Abstract: PURPOSE:To eliminate the necessity of troublesome operations to be carried out by users when the recording medium on the dubbing side terminates while dubbing recording is carried on by automatically rewinding the recording medium to the leading edge section of the dubbing-repeated recording block. CONSTITUTION:While dubbing operations are carried on, a CPU 15 detects the sound recording mode and monitors the output signal of a tape-end detecting means 18. If the output of a no-signal section detecting means 21 indicates a signal existing state when a tape 20 reaches its end, the CPU 15 judges that an interruption takes place at the end of the tape 20 while a piece of music is dubbed and instructs a deck mechanism 17 to rewind the tape 20. If the means 21 detects a no-signal section thereafter, the CPU 15 stops the operations of the mechanism 17. Therefore, users can understand that the dubbing operation is interrupted while the piece of music is dubbed and automatically discriminate the leading edge section of the piece of music. Thus troublesome operations to be carried out by users become unnecessary and the unpleasant feeling which users feel when dubbing operations are interrupted is also removed.
