Abstract: PURPOSE:To form a temperature region which is optimum for a copper vapor laser and a temperature region which is optimum for a gold vapor laser by using heat-insulating materials of different thicknesses in order to insulate heat of a ceramic tube inside a laser tube. CONSTITUTION:A small piece 11 of copper is arranged on the side of a thin heat-insulating material 5; a small piece 12 of gold is arranged on the side of a thick heat-insulating material 6. When an outside diameter of the thin heat-insulating material 5 is made small, this material is made thinner than the thick heat-insulating material 6; a heat-diffusion amount from the surface of the heat-insulating material is increased. A temperature of a ceramic tube 7 supported by the thin heat-insulating material 5 can be lowered. That is to say, thicknesses are controlled by changing outside diameters of the heat- insulating materials 5, 6; the temperature of the ceramic tube 7 is controlled by utilizing a difference in the heat-diffusion amount from the surface of the heat-insulating materials 5, 6. Thereby, a temperature region which is optimum for a copper vapor laser and a temperature region which is optimum for a gold vapor laser can be formed.

Title: Signal-gradient measuring instrument
Inventor: USUI TAKESHI
IPC: G01R19/12
Filed: 1987-04-22
Abstract: PURPOSE:To measure an accurate average value in a short time, by obtaining relationship between a transition time between recognizing levels and a period, and obtaining the value of a signal gradient corresponding to a rotary angle from the ratio between both times and the potential difference between the recognizing levels. CONSTITUTION:First and second comparators 21 and 22 compare the judging levels from D/A converters 11 and 12 and the potential of an input signal 101 to be measured, and the difference is obtained. The result is outputted from the comparators 21 and 22. First and second counters 61 and 62 count reference pulses with a gate signal 106. The ratio between both counted values becomes the ratio between the average period of the rotation of a motor and the average transition time between two judged levels. The signal gradient corresponding to the rotating position is obtained from the relationship between the time ratio and the difference in potentials of the two judged levels. Namely, the signal gradient is obtained by the expression of relation: (average period for one rotation)X(potential difference in two judged levels)/(average transition time between two judged levels).
