Title: Digital-analog converter
Inventor: NAKAI MASAAKI
IPC: H03M1/06
Filed: 1978-11-04
Abstract: PURPOSE: To obtain a highly stable D/A converter which is free from the effect of variation of the temperature and the power voltage by adding the change-over switch, the comparator and others to the double-integration type A-D converter.  
     CONSTITUTION: Change-over switches 11 and 13 are connected to the DA side by the command from control circuit 16 along with switch 10 connected to pint c each, and the integration is started for reference voltage V ref  given from signal source 2 through the integrating circuit consisting of operational amplifier 3, resistance R and capacitor 17 each. At the same time, clock 5 is counted by counter 7, and a comparison is given between the integration value and V ref  at comparator 14. And the counter value M is supplied to arithmetic comparator 8 when the agreement is obtained through the above comparison. In circuit 8 digital value n of input signal V in 1 is memorized, and the operation of n×M/N is carried out with digital value N corresponding to the fixed voltage applied from digital input circuit 19. When this arithmetic value is coincided with the counter output, the operation of the integrating circuit is stopped to hold the so far integration value. This integration value is then delivered from DA out  as the analog signal.

Abstract: PROBLEM TO BE SOLVED: To enhance a heater in output without being limited by a heat deterioration caused by transmitted light in an O-ring, by a method wherein a light source which heats a semiconductor contained in a case is provided to the outside of the case, and projections which project light emitted from the light source provided onto the surface of the case. SOLUTION: When a wafer 102 is heated by light radiating from a heater 103, transmitted light 108 penetrating through a quartz chamber 101 is partly transmitted to the quartz chamber 101 to heat and deteriorate an O-ring. Therefore, the O-ring 107 is preferably formed of material which is high in heat resistance, chemical stability, and flexibility, so that it is preferable that the O-ring 107 is formed of fluororubber. At both an A part and a B part, the transmitted light 108 which heats the O-ring 107 traveling through the quartz chamber 101 is discharged to the outside from tapered parts 109. The outside means the outside of the material of the quartz chamber 101, and the transmitted light 108 may be discharged not only to the outside of the chamber 101 but also to the inside of the chamber 101.
