Title: Incandescent lamp, discharge lamp, and manufacture of lamp
Inventor: GOTO EIZO
IPC: H01K1/54
Filed: 1988-02-10
Abstract: PURPOSE:To prevent the deterioration of a filament and the blackening of a bulb by arranging a getter material from the fused-cutting part of an exhaust pipe toward an exhaust port. CONSTITUTION:Since a getter material 8 is arranged between an exhaust port 6 and the fused-cutting part of an exhaust pipe 5, H2O and a harmful gas released from the exhaust pipe 5 when the exhaust pipe 5 is fused-cut by a burner 9 are absorbed by the getter material 8 and their introduction to the inside of a bulb 1 is prevented. Moreover, since the getter material 8 functions to absorb and remove the escape gas from the inside of the bulb 1 during the lighting, the harmful gas and H2O are never sealed in the lamp, and the escape gas is also never filled therein. Consequently, the evaporation of a filament can be prevented, and a long life of the lamp can be maintained.

Title: Tension measuring device for running yarn
Inventor: YAMAUCHI TOSHIO
IPC: D01H13/10
Filed: 1989-02-08
Abstract: PURPOSE:To make it possible to measure a minute tension variation in running yarn of a winder by installing a sensor, detecting vibration of the running yarn vibrated by an exciter, and a tension detector which finds the number of vibration frequency from the detected vibration and also finds the extent of yarn tension, respectively. CONSTITUTION:Yarn length ranging from a tenser to a package and a yarn diameter are both constant, and when vibration is given to the running yarn Y by an exciter 6, it comes to such a vibration as conformed to tension. Vibration in this running yarn Y is detected by a sensor 7 and vibro-frequency is found out of the vibration by a tension detector 10, while the tension is also found out. Thus, a minute tension variation in the yarn Y during travel can be surely detected.

Abstract: PURPOSE:To put the characteristics of the high hardness and abrasion resistance of B4C to practical use and to cover a low toughness value with a steel plate by laminating and bonding B4C, oxygen free copper, a W-alloy having a predetermined composition, oxygen free copper and the steel plate. CONSTITUTION:B4C1, oxygen free copper 3, a 90-95% W-alloy 2, oxygen free copper 3 and a steel plate 4 are laminated and bonded in this order. Ti- containing silver solder is inserted between the respective materials and said materials are heated under a bonding treatment condition, that is, a temp. condition of 800-900 deg.C in a vacuum chamber and B4C clad steel is obtained by diffusion welding. Oxygen free copper is soft and has an m.p. equal to or higher than that of the solder material and also has good leak properties of soldering and, therefore, said copper is suitable as a stress relieving material. Since the 90-95% W-alloy is hard and the hardness thereof is held even at temp. at the time of soldering, said alloy has the resistance against strain and stress caused by thermal expansion difference and no deformation is generated in the bonded part. Therefore, this clad steel is suitable as a thermal expansion force relieving material.
