摘要： PURPOSE:To provide a method by which a highly accurate laminate of ceramic wiring boards can be thermocompression bonded without fluctuating the distribu tion of shrinkage factor of sinter and the distortion of multilayer interconnection boards nor being affected by the variation of material lots and manufacturing conditions. CONSTITUTION:A top force 4a and bottom force 4b are constituted by forming the outer peripheral parts of the forces 4a and 4b in projecting shapes and central parts of the forces 4a and 4b in recessed shaped and a laminate 1A of green sheets is put between the forces 4a and 4b so as to form the outer peripheral part of the laminate 1A in a projecting shape and the central part of the laminate 1A in a recessed shape. At the time of thermocompression bonding the laminate 1A, the bonding pressure is made uniform on the surface of a substrate by raising the pressure at the outer peripheral part where the pressure is low and, on the contrary, lowering the pressure at the central part.

摘要： PURPOSE:To prevent the uneven deformation of the end faces of green sheets by stacking plural sheets of green sheets, where conductive patterns are printed, after positioning them at the inner wall face of a restricting mold, and thermocompression- bonding the laminate in the condition that the peripheral end face of the laminate of the green sheets is restricted, and then baking it. CONSTITUTION:A press plate 2 is lifted up, and a specified number of green sheets 1, on which conductive wirings are printed and then the peripheries of which are cut off, are stacked in a restricting mold 4. Here, the end face dimensions of the green sheets 1 are a little smaller than the inside dimension of the restricting mold 4, and they are positioned at the inner wall face 4a of the restricting mold 4. Next, it is heated to the thermocompression bonding temperature with a heater 6. When the green sheet gets at processing temperature, compressive force is loaded to lower the press board 2 and thermocompress the green sheets 1. Then, the heating by the heater 6 is stopped, and a a mold releasing frame 19 is placed on the restricting mold 4, and then the press plate 2 is lowered to push down the restricting mold 4, whereby the green sheets 1 are separated from the restricting mold 4. As a result, a molded item with a periphery without uneven deformation can be gotten.

摘要： PURPOSE:To improve the accuracy of a core by pressing a rotatable roll-shaped tool against the outer periphery, inner periphery and slot openings of a wound core and by moving the tool in the direction of the central axis of the core. CONSTITUTION:A wound core 1 is provided with respective pluralities per one round of notches 2, outer peripheral parts 3, teeth 4, slots 5 and slot openings (6a-6d) at uniform spaces. Then, a roll-shaped tool is pressed against the outer periphery 3 or inner periphery of the wound core 1 or inserted into the slot opening 6 and is moved in the direction of the central axis of the core 1. In this case, the outer periphery 3 and tip parts of teeth 4 of the wound core 1 are subjected to plastic deformation so that the outside diameter becomes smaller, the inside diameter and slot openings 6 become larger and respective irregularities become smaller.

摘要： PURPOSE: To judge the cooling characteristic of a cooling fin simply and quickly, by judging the characteristic based on the amount of deviation on the outer surface of the cooling fin, which is caused by distortion of straight lines, being drawn on the surface of a strip plate material in the width direction in advance, caused by the fin molding.
CONSTITUTION: Straight lines are drawn on the surface of a strip plate material 1 in the width direction by a marking needle for a specified length of the strip plate material one by one. Said material is rolled between two rollers 3 and 3 so that compressing rate is linearly changed in the width direction. Then a spiral shaped cooling fin 2 is formed, with the side having small compressing rate being inside. At the same time, the fin is wound around the outer surface of a heat transfer pipe 7 and a heat exchanger 6 is fabricated. The straight line is distorted and becomes a curve 4a at this molding. Based on the amount of deviation δ of the curve 4a on the outer surface of the cooling fin, the cooling performance of the cooling fin 2 for said specified length, with the curve 4a as a center, is judged.
