摘要： PURPOSE:To measure an entire shape only with two laser measuring devices by moving laser beams in a slant direction to a moving direction of a ceramic substrate for scanning. CONSTITUTION:First a master work which has been correctly polished in a size and right angles of corners is supplied, and an outer shape in the vicinity of the corner is measured by laser measuring devices 5,5 respectively. As a result, an edge point of the master work is detected. The result is subjected to arithmetic operation to obtain angles alpha2, alpha3 in scanning directions of the respective laser measuring devices 5,5 so that perpendicular conditions of two sides are satisfied. In addition, correction data deltax, deltay are calculated from the difference between position data calculated from a measurement value of one of the laser measuring devices 5 and position data calculated from a measurement value of the other laser measuring device 5 so that outer shapes measured by the respective laser measuring devices 5 coincide with each other, so as to measure an entire shape.

摘要： PURPOSE:To prevent the generation of bubbles even in the case of a wide junction surface by a method wherein the contact surface between the surface of an insulating material and a liquid to be used as a cathode is diffused in order to apply a DC voltage and an anode is bonded to the insulating material while the contact surface is moved toward the outside from its center. CONSTITUTION:An anode (Si water) 2 brought into contact to one surface of an insulating material 1 is connected to the plasma side of a DC power source. A liquid 7, which is used as a cathode, can be supplied through a pipe 6 connected to the central hole of a metal flat plate 5 held in the vicinity of the surface on the side opposite to the one surface of the material 1. First, the whole is heated at 300-400 deg.C to supply the liquid 7 to the central part of the flat plate 5. As a result, a DC voltage is applied to the part only of the center of the material 1, a polarization that such cations as Li , Na and K ions in this part turn to the cathode side and such anions as O + ions turn to the side of the anode 2 is generated, the O + ions couple with Si ions and so on in the cathode and the bonding of the anode is performed. The bonding is performed while the contact surface between the liquid 7 and the surface of the insulating material is diffused in order and the junction interface is moved toward the outside from its center.

摘要： PURPOSE:To eliminate warpage and the deterioration of the surface layer part of an insulating material, which are caused by the segregation of alkali, by a method wherein alkali salt, which is brought in a fused state at a joining temperature, is used as a cathode brought into contact to the surface opposite to an anode provided on one surface of the insulating material. CONSTITUTION:An anode 2 is brought into contact to one surface of an insulating material 1, a cathode 5 is brought into contact to the opposite surface and the DC voltage of a DC power source 4 is applied to perform the joining of the anode 2. As the cathode 5, alkali salt, which is brought in a fused state at a joining temperature, is used. As such alkali ions as Na , K and Li ions, which are moved in the insulating material at the time of joining the anode and are segregated on the side of the cathode 5, are dissolved and absorbed in the alkali salt which is in a fused state, the segregation of alkali is never generated in the surface on the side of the cathode 5 of the insulating material 1.

摘要： PROBLEM TO BE SOLVED: To measure the existence of a defect and its size using a simple method and device by transducing two bright line reflection rays appearing by reflection at the corner portion of an opening top face inside into electric pulses, capturing the same, and comparing the interval and the duration time of the electric pulses with threshold values. SOLUTION: Arc-like bright line reflection rays appearing by reflection at the corner portion of an opening top face inside by projecting light on the opening top face inside through projectors 103, 104 are captured by one- dimensional cameras 105, 106 having visual fields orthogonal to the reflection rays and are transduced into electric pulses. Two bright line reflection rays, which appear by the reflection at the edge portion by the in-opening extrusion or in-opening steps 101, 102 and an opening point face inside corner portion formed along the opening top face inside corner in a vessel-forming process, are transduced into two electric pulses and are captured, and the intervals and the duration time of the two electric pulses are obtained so as to compare with a previously set threshold value to judge good or bad.

摘要： PURPOSE:To provide a method improved in both workability and safety, so designed that anode is brought into contact with one side of an electrical insulating material and a porous plate serving as cathode is brought into contact with the opposite side followed by injecting direct current into the resulting circuit. CONSTITUTION:An electrical insulating material 1 is heated to 300-400 deg.C with a heater 8, and an alkali salt as a liquid electrode is fed in a molten state through its feed port 4 onto the surface at the center of a porous plate serving as cathode 3; concurrently, a direct voltage is applied from a direct current source 7 on both anode 2 and cathode 3. Then, the porous plate is impregnated with the liquid electrode, and anode jointing is started at a portion of the liquid electrode diffused on the surface of the electrical insulating material 1, and the jointing part is gradually expanded toward the outer periphery as the liquid electrode is diffused, thus accomplishing the objective anode jointing.

摘要： PURPOSE:To provide excellent heat dissipation by forming a ceramic layer on a base metal, and further forming a thinner porcelain layer than the ceramic layer thereon. CONSTITUTION:Since a porcelain layer 3 having low thermal conductivity is reduced thinner than a porcelain coating board, heat generated from an electronic circuit rapidly arrives at a ceramic layer 2, and further diffused from a base metal 1. Since the layer 2 performs a buffer effect for a large thermal expansion coefficient of the metal 1 and a thermal expansion coefficient of the layer 3, the coefficient of the layer 3 can freely be decided to match to that of the circuit. Accordingly, since the layer 3 is not affected by the influence of a residual distortion, etc., and adverse influence to the thermal characteristic of the circuit can be avoided, the circuit having high reliability can be formed. Further, since the layer 3 is not directly formed on the metal 1, other metal material such as stainless steel can be used.
