Title: Packaging structure for semiconductor device
IPC: H01L21/52
Filed: 1992-03-19
Abstract: PURPOSE:To prevent stress concentration by equalizing the thickness of a joint section between a semiconductor pallet and a mount section and provide a mounting structure for a semiconductor device having high strength against shearing stress accompanied by the heat generation of a pellet. CONSTITUTION:A semiconductor pellet 1 is bonded with a mounting section 101 with a brazing material 111. Fine particles (Cu ball) 112 comprising a higher melting point material are mixed with the brazing material 101. The fine particles are contained in the brazing material 101 at a specified rate before they are joined. When the brazing material is melt when they are joined, the fine particles function as a spacer, which makes it possible to equalize the thickness of a connection section between the mounting section 101 and the pellet 1.

IPC: G01N21/75
Filed: 1984-03-31
Abstract: PURPOSE:To obtain a safe and highly reliable hydrogen detector by detecting hydrogen only by optical action. CONSTITUTION:In the hydrogen detector 15 to which inputting and outputting optical fibers 16, 17 are connected at respective end surfaces of a single mode light introducing path 12, if hydrogen surrounding the detector 15 is adsorbed to a thin film 14, hydrogen is separated to proton and electron by the catalytic action of the film 14. Said proton and electron furthermore react with a thin film 13, the ratio of evanescent wave absorbed to the film 13 is increased in the light propagating in the path 12, consequently the propagated light quantity is decreased. Thus, by setting the length of the path 12 covered with the films 13, 14 to the suitable value, the propagated light quantity is decreased thoroughly, and the hydrogen detection becomes possible. Since hydrogen is detected optically by the propagated light quantity variation, there is no danger of explosion and no erroneous operation due to electromagnetic induction, the safe and highly reliable hydrogen detector can be obtained.

Filed: 1988-03-17
Abstract: PURPOSE:To obtain a satisfactory result of cooking as far as the same sorts of cooking are performed even if patterns of steam generation from food in a heating compartment differs in each case, by dividing a heating course in a cooking sequence into two or more stages corresponding to the degree of steam generation during cooking. CONSTITUTION:In case of boiling, a difference between VS1 and VS2 is calculated, where VS1 and VS2 represent voltages corresponding to detected humidity at 15seconds and 2minutes after the start of heating respectively, and when the difference represents specified increasing rate of 0.5volts or higher, heating continues until the humidity reaches No.1 humidity level VSA1=VS1+2.5volts. When it is 0.1volts or higher and less than 0.5volts, heating continues until the humidity reaches another No.1 humidity level VSA1=VS1+2volts. Next, in any case, heating continues further at 50% output for a period of time equal to TAXK1, where TA represents a period of time required for the humidity to reach No.1 humidity level, and K1 a factor. When the differential voltage is less than 0.1volts, a humidity level is set at No.2 humidity level VSA2=VS1+0.3volts, and after heating continues until the humidity reaches VSA2, heating continues further at 50% output for a period of time equal to the time required for the humidity level to reach VSA2 multiplied by a corresponding factor. Thus, an optimum result can be obtained according to volume to be cooked and whether a lid is used or not.
