Title: Weld seam detecting method of automatic welding equipment
Inventor: KOMATA HITOSHI
IPC: B23K9/095
Filed: 1992-06-23
Abstract: PURPOSE:To correctly judge the weld seam position by detecting the surface temperature in the vicinity of the weld seam of a work to be welded, and judging that the direction where the reduction ratio of the surface temperature is largest is the weld seam position. CONSTITUTION:Butt welding of works 5, 7 to be welded is executed. The surface temperature of the works 5, 7 to be welded in the vicinity of the weld seam L which is the groove is detected by a surface temperature detector 15. The welding heat is radially transmitted from a molten pool P immediately below a welding torch 13, and shows the temperature distribution whose shape is like the contour of a longitudinally-cut apple as demonstrated like the isothermal lines a1, a2.... The reduction ratio of the surface temperature becomes largest in the direction of the weld seam L due to the groove. The position can correctly be judged by making a judgement that the direction where the reduction ratio of the surface temperature is the largest is the weld seam L. Since this detecting method is of non-contact type, and no effects are made on the welding heat and wears, and the durability is also excellent. Correct judgement can be made even when the plate thickness is small.

Filed: 1992-06-01
Abstract: PURPOSE:To automatically adjust a minute defocus and to record in a best focus point by generating an RF signal while recording and correcting a focus error signal based on the signal level of the RF signal.

Title: Manufacture of voltage-nonlinear resistor
Inventor: TAKADA YUTAKA
IPC: H01C7/10
Filed: 1987-07-03
Abstract: PURPOSE:To obtain a long-lived device whose electrical characteristic is excellent by a method wherein, after three kinds of specific oxides have been mixed and then baked, they are heattreated after a polishing process. CONSTITUTION:Bismuth oxide (Bi2O3) and another oxide are mixed with zinc oxide; they are baked; after that, a polishing process is executed. They are heat-treated after this polishing process. A condition for this heat treatment is not specified especially, but it is preferable that the heat treatment is executed in an oxidizing atmosphere, preferably in the air, at a temperature of about 300-600 deg.C for a duration of about 30 minutes -4 hours. If a treatment temperature is lower than 300 deg.C, an effect to improve a characteristic of an obtained voltage-nonlinear resistor is low. On the other hand, it the temperature exceeds 600 deg.C, an unnecessary phase transition or the like is caused, so this temperature is not desirable. In addition, if the treatment duration is shorter than 30 minutes, the effect to improve the characteristic is insufficient; if the duration exceeds 4 hours, this causes a negative effect and is not desirable.

Title: Measuring instrument
Inventor: NAGAO TOSHISHIGE
IPC: G01L1/24
Filed: 1984-08-08
Abstract: PURPOSE:To eliminate an error due to variation in the optical transmissivity of an optical fiber and to obtain precise measured values by converting light components which are transmitted from two light sources by one optical fiber and differ in wavelength into electric signals, and then processing the signals corresponding to the wavelengths as specified. CONSTITUTION:Light with different wavelengths lambda1 and lambda2 from the light sources 1a and 1b are multiplexed by a multiplexer 21, propagated in the optical fiber 2 to enter a polarizer 4, and converted into linear polarized light waves, which enters a photoelastic element 5. A shift in phase corresponding to a wavelength given by the element 5 to linear polarized light which is incident is converted into variation in light intensity by an analyzer 7 through a quarter- wavelength plate 6. Therefore, the projection light of the analyzer corresponding to pressure applied to the element 5 varies with wavelength. For the purpose, the light components with the wavelengths lambda1 and lambda2 are converted by photoelectric converters 12a and 13a into electric signals, which are processed as specified into signals corresponding to their wavelengths, thereby calculating optical modulation corresponding to an object physical quantity. Consequently, variation in the optical loss in the optical fiber does not appear in an error.
