Title: Device for monitoring gas lfakage to cooling water circulating system
Inventor: HATAKEYAMA MINORU
IPC: H02K9/24
Filed: 1996-07-02
Abstract: PROBLEM TO BE SOLVED: To noticeably detect the leakage of a gas to a cooling water circulating system including the quantity of a gas discharged into an atmospheric escape pipe by measuring the quantity of a gas flow through the atmospheric escape pipe and detecting the leakage of the gas when the quantity measuring signal of the gas flow exceeds a preset criterion. SOLUTION: When the internal hydrogen gas of a hydrogencooled turbine generator 1 leaks to the cooling water circulating system 5 of a stator winding 2, the hydrogen gas flows in the water tank 4 of a cooling water device 3 and, after a gas flowmeter 12 measures the leak quantity of the hydrogen gas, the hydrogen gas is discharged to the atmosphere from an atmospheric escape pipe 7. The quantity measuring signal of the leak gas obtained by the gas flowmeter 12 is inputted to a detecting and monitoring unit 14 together with the temperature detecting signal of a temperature detector 10 which detects the temperature of returned cooling water and the signal detecting the pressure in the upper space in the tank 4. When the flow rate of the gas and the pressure in the upper space in the tank 4 are larger than the preset criterion, the unit 14 outputs an alarm signal.

Title: Mask and wafer aligning method
Inventor: KUROKI YOUICHI
IPC: H01L21/30
Filed: 1981-10-28
Abstract: PURPOSE:To realize precise alignment between mask and wafer by identifying each pulse signal whether it is the pulse for mask alignment mark or wafer alignment mark. CONSTITUTION:The counter circuits 24-27 respectively count up the rising edges of pulse signals from alignment marks on the mask and wafer and the counter circuits 28-31 count up the falling edges of them. A shift register 22 sequentially sets outputs Q1-Q4 to a high level for each rising edge of pulse signal sent from a comparator 9. A shift register 23 sets outputs Q1'-Q4' to a high level for each falling edge of pulse signal and stops operations of the circuits 28-31. Thereby, the circuits 24-37 store the rising position of pulse signals, while the circuits 28 31 stores the falling position of signals. A central porcessing unit CPU20 reads these stored positions and obtains an interval between the centers of pulses and pulse width. Moreover, the CPU20 identifies the wafer alignment mark from the pulse width for alignment.
