Title: Composite semiconductor substrate
Inventor: ASARI GORO
IPC: H01L21/02
Filed: 1989-06-06
Abstract: PURPOSE:To obtain a substrate for electric power which is superior in thermal characteristics by control the thermal expansion coefficient of the substrate so that its coefficient is matched with that of an intended semiconductor. CONSTITUTION:Junction between two different substrates 4 and 6 of AlN and Si is performed through an intermediate layer 5. In such a case, the thermal expansion coefficient of the substrate 4 is regulated so that its coefficient becomes equal to that of the substrate 6. When the other GaAs layer is allowed to perform an epitaxial growth for LEDs, FETs and the like on a composite semiconductor substrate, the thermal expansion coefficient of the substrate 4 is equalized to that of GaAs and when a semiconductor element and the like are formed directly on the substrate 6, each thermal expansion coefficient is adjusted to that of Si. Further, the junction surface of the substrate 4, the thermal expansion coefficient of which is adjusted in advance to intended value, is ground to have an exceedingly flat surface and is finished to obtain a mirror surface. After depositing an SiO2 layer 5 on the above surface, the substrate 6 is put on top of the preceding surface by applying a pressure on the substrate 6 which is finished in the same manner and then, its substrate is treated with heat. The substrate 6 is thus bonded firmly onto the substrate 4.

Title: Superconducting transistor
Inventor: MATSUI TOSHIYUKI
IPC: H01L39/22
Filed: 1993-06-15
Abstract: PURPOSE:To facilitate the manufacturing while enhancing the reproducibility and reliability by applying a voltage to the gate electrode while placing a superconducting transistor in an external magnetic field to modulate the flux restriction force in the center of capturing thereby controlling the critical value of superconducting current flowing between the source and gate. CONSTITUTION:Multiple crystal grain boundaries are provided, as the center for capturing the magnetic flux, in the channel region layer of an oxide superconductor layer 20. When the energy imparted to the magnetic flux by the current flowing between the source and drain exceeds the restriction force, the flux restricted to the center of capture begins to shift in a predetermined direction. Consequently, the oxide superconductor layer 20 makes a transition to normal conducting state. When a voltage is applied to the gate electrode 23 formed on the channel region layer of the oxide superconductor layer 20, the width of spatial charge layer varies to modulate the Up. Consequently, the current level (critical level) produced by the source/drain voltage varies according to the variation of gate voltage thus realizing the voltage driven operation of the superconducting transistor.

Abstract: PURPOSE: To improve the cooling effect of an integrated circuit by mounting a plurality of integrated circuits in rows on a printed circuit board to pass cooling fluid through both sides of respective rows in such a manner that the integrated circuits are laterally displaced with respect to the flowing direction of the cooling fluid.  
     CONSTITUTION: A number of integrated circuits 2 are so mounted on a printed circuit board 1 to pass cooling fluid through both sides of respective rows as to retain the space for passing the cooling fluid at both sides of the rows. The integrated circuits 2 of the respective rows are so displaced laterally, for example, perpendicularly to the direction of the cooling fluid flow as not to exceed the width of the integrated circuits 2 at one every other circuits 2. Thus, there occur fluid pressure increase and decrease in the vicinity of both ends laterally between the integrated circuits 2a and 2b projected toward the cooling fluid flow to thereby cause induction stream 4 and longitudinal vortex 5 along the integrated circuits 2, and the integrated circuits 2 are accordingly uniformly and effectively cooled to reduce the size of high packing density mounting structure and to increase the integration of the integrated circuits 2.

Title: Transfer system for measured value
Inventor: SUZUKI NOBUYUKI
IPC: H04Q9/00
Filed: 1988-06-13
Abstract: PURPOSE:To attain accurate recognition of fluctuation of a measured value at a collection station and to relieve the communication load by decreasing a threshold value of a station measuring the measured value as the elapsed time. CONSTITUTION:A measuring station measuring the measured value is provided with a clock counter 11 reset at the start of measurement, counting a clock pulse and outputting the count. A function circuit 12 receives the count as the elapsed time (t) and outputs the calculation value of y=f(t) as a threshold value, the threshold value is decreased as the elapsed time according to the time function y=f(t) and it is repeated every time the clock counter 11 is reset. Thus, the measuring station sends a measured value only when the change in the count is large at the initial state. Since the threshold value is decreased with the elapsed time, even if the change in the measured value is small, the measured value is sent from the measuring station. Thus, the communication load is relieved and the accurate measured value fluctuation at the collection station is recognized.
