Title: Electrostatic protector for semiconductor integrated circuit device
Inventor: MIURA KEIJI
IPC: H01L27/04
Filed: 1990-10-24
Abstract: PURPOSE:To reduce the number of the elements needed for an electrostatic protecting circuit by providing a bipolar transistor whose collector is connected to the first grounding terminal and whose emitter is connected to the second grounding terminal, and a means for applying a bias voltage to the base of the bipolar transistor. CONSTITUTION:When an electrostatic surge positive to the potential of a ground terminal 1, this electrostatic surge is absorbed by the breakdown current between the collectors and emitters of bipolar transistors 3, 7. On this occasion, voltages appear between both terminals of resistors 5, 9 owing to the breakdown current between the collectors and emitters of the bipolar transistors 3, 7. Then, the paths between the emitters and bases of the bipolar transistors 3, 7 are brought into an on-state turning the bipolar transistors 3, 7 on. Accordingly, the electrostatic surge is drawn off quickly.

IPC: F01D17/00
Filed: 1987-11-13
Abstract: PURPOSE: To maintain a steam temperature at the entrance of a turbine at an appropriate value and make smooth a load change by calculating the amount of drop of the steam temperature during passage through an adjusting valve based on the value travel of the adjusting value at the entrance of the turbine, a steam temperature and a pressure at the entrance of the valve and correcting a main steam temperature set signal based on the calculated value. CONSTITUTION: A steam table reference element 111 obtains a specific volume signal 112 and an enthalpy signal 113 of the entrance steam of a valve 59. A valve characteristic function element 114 obtains the passage flow rate of the valve 59 from pressure- flow rate characteristics, calculates a valve differential pressure from it, and outputs it as a pressure loss signal 115. A signal subtraction element 116 subtracts the signal 115 from a signal 10 and obtains a valve exit pressure signal 117. A steam reference element 118 obtains a temperature signal 119 corresponding to the exit pressure of the valve 59 with enthalpy that is equivalent to that of the entrance of the valve 59. A signal subtraction element 120 subtracts a signal 119 from a signal 26 and outputs a temperature drop width signal 121.  A signal-setting element 122 gives a desirable steam temperature set value 123 for the exit of the valve 59. A signal-adding element 124 adds the signal 121 to the set value 123 and outputs a steam temperature set signal 102.
