Title: Method and device for measuring thickness with ultrasonic wave
Inventor: FUJITA YASUNOBU
IPC: G01B17/02
Filed: 1987-06-11
Abstract: PURPOSE:To measure the accurate thickness of a material to be inspected even when the material is a special material or corrosive material by deleting an abnormal value among >=3 measured values and displaying the mean value of measured values which are not abnormal as a final measurement result. CONSTITUTION:An ultrasonic pulser 2 receives the signal of a trigger circuit 1 and inputs a sent pulse to a sensor 3, which sends an ultrasonic wave signal to the material 4 to be measured and receives a reflection echo. Then a comparator 4 compares the received signal amplified by an amplifier circuit 5 with the reference voltage value 14A of a reference circuit 14 to input a signal which exceeds the voltage value 14A to a memory address counter 7 and a timing circuit 8. Then the counter 7 counts up each other the signal exceeds the voltage value 14A and inputs it to a memory 9. Here, a computing element 12 reads record data out of the memory 9 to calculates the time interval between the transmission and reception, compares at least three transmission-reception intervals to delete abnormal values, and calculates the thickness of the material 4 to be inspected from the mean values of intervals except the abnormal values, thereby displaying the accurate value on a display device 13.

Title: Methal vapor discharge lamp
Inventor: OOTANI KATSUYA
IPC: H01J61/36
Filed: 1980-10-17
Abstract: PURPOSE:To prevent the insufficient starting and crack at the tube end, by setting the thickness per unit rated power in the axial direction of a ceramic cap for choking both ends of a light emission tube to predetermined condition thereby protecting the tube wall and the electrode from adhering with the amalgam. CONSTITUTION:In a cap 2 made of ceramic for choking both ends of a light emission tube 1 encapsulated with sodium, mercury, the following relation t/W>=0.2X 10<-2>(mm./W) is set between the thickness (t) (mm.) in the axial direction of a cap 2 and the rated power W(W) of the discharge lamp. In other word the thickness of the cap 2 is increased to increase the thermal transmission thus to quicken the cooling speed at the coolest section at the end of the light emission tube. Consequently immediately after the unlighting of the discharge lamp, the temperature of the electrode 6 will never drop below the temperature at the coolest section at the tube end. Since the amalgam will never adhere to the tube wall or the electrode 6, the insufficient strating and the crack at the tube end can be prevented.
