Inventor: KUBOTA SHIGERU
IPC: G01R1/06
Filed: 1991-02-14
Abstract: PURPOSE:To achieve a highly accurate mass production by placing a plurality of terminal pieces consisting of a narrow and long metal thin-plate piece on an upper surface of an insulation holder where a groove is formed at a center of an upper surface symmetrically left and right In parallel while a set spacing is provided between opposing terminals. CONSTITUTION:In a measurement terminal A, 16 terminal pieces 2a consisting of a narrow and long metal thin-plate piece which is a terminal 2 where a tip portion contacts an electrode 1 of a chip t are formed on a groove 5 at a center on an upper surface, eight terminals are placed symmetrically left and right in parallel on an upper surface of an insulation holder 7 where an elastic material 6 such as urethane is filled into this groove 5 while a set spacing L is provided between opposing terminals 2, 2, and then each terminal 2 is sealed and installed while it protrudes above the groove 5 at the center of the holder 7. The measurement terminal A achieves measurement while it is in contact with the electrode 1 of the chip t from a bottom surface side. When the chip t is mounted on each terminal 2 of the measurement terminal A and then the chip t is pressurized and pushed down from an upper portion, the terminal 2 contacts the electrode 1 and is slightly deflected but at the same time it is repelled by the elastic material 6 within the groove 5 and is maintained to be in an accurately contact, thus enabling conduction of current to be measured in a stable state. In the measurement terminal, the metal thin plate is subjected to chemical etching machining for forming each terminal piece 2a, which is suited for mass production, and an extremely narrow terminal which is 0.1mm or less can be manufactured easily and accurately.

Abstract: PURPOSE:To prevent the temperature rise of a bush section and prevent the hardening of thermoset resin in the bush by a method wherein a heat pipe is constituted so as to have the spool bush as a heating section and the cooling section of said pipe is cooled from the outside of the mold. CONSTITUTION:The spool bush 20 is employed as the heating section of the heat pipe while a radiating fin 24 is employed as the cooling section of the heat pipe and both of them are connected by a pipe 23 filled with operating liquid. When heat is applied to the bush 20, the operating liquid absorbs the heat from the bush and is evaporated, then, is brought to the radiating fin section 24 being cooled by a fan 26 and is cooled, thereafter, is returned to the bush 20 again. The control of the temperature of the heat pipe is effected by detecting it with a temperature detecting element 25 and controlling the operation of the fan 26 through a control circuit 27. The temperature rise of an inner tube 22 is prevented by the effect of the heat pipe, therefore, poured resin will never be cured in a spool forming hole 10 by heat resulting in blocking said forming hole 10.
