Title: Reference temperature source apparatus
Inventor: KUROKAWA MASARU
IPC: G01J5/00
Filed: 1989-03-02
Abstract: PURPOSE:To enable accurate measurement with one black body by developing a specified temperature difference between one end and the other end of a metal body while a plurality of black body sections are formed therebetween. CONSTITUTION:When one end 21a of a metal body 21 is cooled with an electronic cooling element 23 while the other end 21b thereof is heated with a heater 24, a temperature difference is developed between one end 21a and the other end 21b thereof, which in turn generates a temperature gradient between one end 21a and the other end 21b thereof 21. Hence, a radiation energy level varies among black body sections 22 to make them as a reference temperature source with a temperature difference. Moreover, the black body sections can produce any fine temperature difference as desired by varying a position where they are set and a shape or the like of the metal body 21. Thus, a photographing is performed directly with a thermography device using the black body section 22 as reference temperature source thereby enabling direct evaluation with only one black body.

Abstract: PROBLEM TO BE SOLVED: To enhance high frequency characteristics of a semiconductor device. SOLUTION: Inside a semiconductor element, an emitter conductive part comprising a p<+> type silicon substrate 10 and a p<+> type emitter burying region 14 and a p<+> type emitter lead-out region 20 is formed. The p<+> type silicon substrate 10 of this semiconductor element is bonded to an emitter lead frame ERF, and an emitter electrode E is electrically connected to the emitter lead frame ERF at this emitter conductive part. Thereby, it is possible to abolish an emitter bonding wire connecting the emitter electrode E to the emitter lead frame ERF, and to remove impedance caused from this emitter bonding wire. Therefore, it is possible to enhance high frequency characteristics of a semiconductor device.

IPC: H01L31/04
Filed: 1989-03-02
Abstract: PURPOSE: To expose a web to the atmosphere without absorbing contaminants from the atmosphere during transferring the web to a second apparatus to weld amorphous silicon thereto, by sealing the first and second principal surfaces of the web. CONSTITUTION: Putting the roll or web of a polymer film in a vacuum chamber 10, the web is first degassed in a degassing process 6 to seal the first and second principal surfaces of the web. Then, both the surfaces of the degassed web are etched or scribed in a high-voltage oxygen etching process 7. Next, both the sides of the etched web are coated with stainless steel in a coating process 8. In this process, the end surfaces of the web are also coated with stainless steel. Since stailess steel surrounds the surfaces of the web to seal them, stainless steel becomes a barrier for the movements of gases from/to the web. The product at this time becomes a polyimide web with the sealing layer made of stainless steel. On the surfaces of the coated web, a conductive contact layer made of a metal is welded in a welding process 9 to form an amorphous silicon device out of the coated web.  Preferably, the conductive contact layer may be an aluminum layer welded to one side of the coated web with stainless steel.

Title: Flash electric discharge device
Inventor: OZAWA MASATAKA
IPC: G03B15/05
Filed: 1979-04-26
Abstract: PURPOSE:To stop continuous electric discharge securely and enhance the safety, by providing a continuous discharge stopping circuit in a flash electric discharge device. CONSTITUTION:A continuous electric discharge stopping circuit 19 is composed of a timer circuit 20, a holding circuit 21, and an AND gate 14. When recharging immediately after flash emission, since a charging current flows in a flash discharge tube 7, the voltage in a discharge capacitor 6 does not rise, and the output of a charge completion voltage comparator 13 remains high level and the output of the AND gate circuit 14 also remain high level. As this state continues for a specified time, the output of the timer circuit 20 rises to become high level. As a result, the holding circit 21 is set and its output becomes low level, and one of the inputs of the circuit 14 becomes low level and the output drops to low level. Upon becoming low level, a power switch 16 is opened, and the circuit 20 is reset, so that the output becomes low level. However, the circuit 21 is not reset and is held in low level, and the switch 16 also remains open. Thus, when continuous discharge occurs, it is detected and subsequent charge is automatically stopped.
