Title: Brazing material for ceramic
Inventor: MATSUZAWA OSAMU
IPC: B23K35/30
Filed: 1991-11-11
Abstract: PURPOSE:To obtain a brazing material capable of brazing ceramics at low temperatures because the thermal expansion of the brazing material causing the generation of cracks is reduced, by specifying a composition by the addition of Ge to an Ag-Cu-Sn brazing material. CONSTITUTION:The brazing material comprises 18-60wt.% of Ag, 20-50wt.% of Cu, 18-35wt.% of Sn and 1-5wt.% of Ge. Since the brazing material has a low melting point, the brazing temperature of ceramic is lowered and the difference in thermal expansion between the ceramic and the brazing material is reduced, whereby the generation of cracks in the ceramic is reduced. When the amount of the Ag is below the lower limit, the wettability of the ceramic is lowered, and when the amount of the Ag is above the upper limit, the wettability is enhanced. When the amount of the Cu is below the lower limit, the wettability can not be maintained, and when the amount of the Cu is above the upper limit, the ceramic is embrittled. The Ge lowers the melting point of the brazing material to improve the flowability of the brazing material, but when the amount of the Ge is below the lower limit, the flowability can not be improved and when above the upper limit, the flowability is deteriorated.

Title: Current detecting circuit, overcurrent detecting circuit, and power supply
Inventor: OKAMOTO YUJI
IPC: H02H3/08
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a current detecting circuit, an overcurrent detecting circuit, and a power supply which stably detect a, without being affected by the change in ambient temperature. SOLUTION: An overcurrent detecting circuit 28 in a power supply is provided with a current transformer T1, a rectifier diode D1, a smoothing capacitor C1, a resistor R1 and a transistor Q1. Furthermore, a resistor R2 and a diode D2, which has a forward voltage VF close to the temperature characteristic of a transistor Q2, are connected in series between the base of the transistor Q1 and a ground GND. A current Ir1 which flows through the resistor R1 is shunted at a point B into a current IB to the base of the transistor Q1 and a current If to the resistor R2 and a diode D2.  As a result, the changes in the current Ir1 and current IF can be suppressed to a low level, even if ambient temperature changes to a higher side, for instance, because the temperature characteristic of the detected value of this circuit does not depend on the temperature characteristic of the transistor Q1, and the effect due to the change in the ambient temperature is reduced.

Title: Production of optical cable
Inventor: ISHIKAWA MASATO
IPC: G02B6/44
Filed: 1987-12-23
Abstract: PURPOSE:To prevent microbending of an optical fiber which occurs in shrinkage of a covering by covering an optical fiber bundle while applying the tension conforming to the quantity of the shrinkage occurring in the work strain and thermal strain of the covering to said fiber bundle. CONSTITUTION:The optical fiber bundle 2 is subjected to the covering 2 while the tension to impart the elongation strain conforming to the quantity of the shrinkage occurring in the work strain and thermal strain of the covering 3 is kept applied to the fiber bundle. The optical fiber 1 after the covering is, therefore, in the state of being applied with the elongation strain. This elongation strain coincides nearly with the quantity of the shrinkage occurring in the work strain and thermal strain of only the covering 3. The covering 3 is thereby shrunk with age after covering and the strain of the optical fiber 1 is decreased until finally the strain is decreased to nearly zero.
