Title: Detector for weld line
Inventor: MURAKAMI EISHIN
IPC: B23K15/00
Filed: 1981-03-02
Abstract: PURPOSE:To suppress the influence of metallic vapor and sputters or electrical noises in a device of detecting the line to be welded, by using the X-rays generated when electron beams collide against the work. CONSTITUTION:The electron beam 8 from an electron gun 1 is focused by a focusing coil 3 onto the work 6; at the same time, it scans on the scanning line B crossing the line 7 to be welded of the work by a deflection coil 4 driven by the deflection current from a signal generator 15. When the electron beam collides against the work, X-rays 25 are generated. The intensity thereof is smallest when the collision position is on the weld line 7 because the beam penetrates deeply into the joint and the X-rays are shielded by the work. The quantity of the X-rays is sufficiently large and can be detected with a photodiode 26 or the like coated with metal. If this is displayed with an oscilloscope 18, the position of the weld line is discriminated from the position at the min. point thereof.

Title: Production of mesh for screen printing
Inventor: NAKANISHI NOBORU
IPC: B29C59/14
Filed: 1987-02-13
Abstract: PURPOSE:To enhance adhesiveness of a mesh to a photosensitive resin and mechanical strength of the mesh, by subjecting a polyester mesh to a low-temperature plasma treatment through using an inorganic gas having an ionization energy of not less than a specified value and specifying the pressure, a high-frequency electric power applied to an input-side electrode and an applied discharge energy. CONSTITUTION:A mesh for screen printing is produced by subjecting a polyester mesh to a low-temperature plasma treatment through using an inorganic gas having an ionization energy of not less than 15eV under the conditions of a pressure of 0.001-10Torr, a high-frequency electric power applied to an input-side electrode of not more than 150kW/m<2> and an applied discharge energy of 10-1,000kW.S/m<2>. If the power applied across the electrodes is excessively high, the material being treated is decomposed or deteriorated, causing a decrease in the strength of the mesh. Therefore, the power applied across the electrodes is controlled to or below 150kW/m<2> per area of the anode. The inorganic gas may be He, Ne, Ar, H2, N2 or the like. An inorganic gas having an ionization energy of less than 15eV, such as O2, air, CO and CO2, is liable to cause excessive etching of the surface of the mesh, leading to a decrease in the strength of the mesh.

Title: Thermistor for detecting microwave
Inventor: HIRAMA MASAHIRO
IPC: G01R29/08
Filed: 1994-03-02
Abstract: PURPOSE:To improve sensitivity for output in an area having a small microwave input, to enhance detecting sensitivity when there is an element to be heated and to prevent a thermal shock to a thermistor element when there is no element to be heated by limiting characteristics of the thermistor element. CONSTITUTION:When a resistance value (R25) of a thermistor element of a detecting thermistor of a microwave detector is less than 1000OMEGA, its change amount of a resistance value in the case of a temperature change is small and its detecting sensitivity is raised. On the other hand, when the R25 exceeds 10kOMEGA, detecting sensitivity, when a microwave oven output is low, is lowered. Then, a thermistor element having a range of 1000OMEGA-10kOMEGA of the R25 is used. Or a thermistor element having this range of the R25, a range of B constant of 30003-5000K and a heat dissipating constant of a range of 1-3mW/ deg.C is used. As a result, the microwave can be detected with high sensitivity. Since a thermistor output is not abnormally increased when there is no element to be heated, a thermal shock of the element can be prevented.
