Abstract: PURPOSE:To realized effective cooling, by constituting a cycle wherein refrigerant is supplied to a transformer cooling tank from the lower part, and the overflowing refrigerant is dropped along the inner wall of the tank, which is supplied to a refrigerant tank. CONSTITUTION:Heat generated in a transformer winding 2 and an iron core 3 is absorbed by refrigerant 4, and the temperature of the refrigerant in a tank rises. The refrigerant 4 whose temperature is decreased by a cooling equipment 10 is again supplied from the bottom of a refrigerant tank 5 via a feeding pipe 7, and the inside of a transformer is effectively cooled. When the refrigerant 4 having absorbed heat reaches the upper surface of the tank 5, it is poured on the side surface of the tank 1 and a magnetic shielding plate 12, after travelling a refrigerant guide 11, so that the whole part of the tank 7 is uniformly cooled. Since a small cooling holes are arranged in the midway of the guide 11, the refrigerant 4 drops like shower in the tank 1, and absorbes heat from insulating gas 8 exitisting in the midway. Then the refrigerant 4 returns to the lower part of the tank 5 through the feeding pipe 7, a pump 6, and the cooling equipment 10.

Title: Adjusted bicmos output buffer
IPC: H03K19/0175
Filed: 1992-09-17
Abstract: PURPOSE: To improve an interface to various loads such as a 3.3V integrated circuit. CONSTITUTION: An output buffer 34 applies a first voltage to the base of a pull-up transistor TR 116 in response to the difference between an input voltage and a reference voltage. The emitter of the pull-up TR 116 generates an output signal. A second TR 102 which has a characteristic coinciding with that of the pull-up TR 116 receives the first voltage by its base and generated an input voltage by the emitter. The output buffer 34 changes the first voltage until the voltage of the base of the second TR 102 is equal to the reference voltage. Therefore, signal reflection on the output signal has no influence upon the performance of the output buffer. Clamps 99 and 120 coupled to the base and the emitter of the pull-up TR 116 perform soft clamping in accordance with a square law.
