IPC: G06F13/00
Filed: 1978-02-08
Abstract: PURPOSE: To ensure an highly effective use of cash memory CM by detecting the address where the contents of main memory MS is renewed via the input/output control unit to inform it to CPU and then repealing the CM of the address via CPU.  
     CONSTITUTION: CPU1 contains CM and stores the necessary data into CM from MS2. When CPU1 processes the order of MS2 and the input/output order is given, the input/output transfer control command is set to the specified region of MS2 and then the input/output operation is indicated to input/output control unit IOC3. Thus, IOC3 accepts the indication and reads out the information of the address or the like necessary for the data transfer from MS2 to set it to data transfer unit 4. When IOC3 completes the data transfer, the address of the renewed region of MS2 is detected via the data transfer to be informed to CPU1. Thus, CPU1 repeals the block of the CM shown by the address. As a result, only the CM that corresponds to the nenewed address of MS is rewritten, ensuring a highly effective system.

IPC: H01L21/58
Filed: 1979-02-09
Abstract: PURPOSE: To prevent cracks of chips and fatigue rupture of jointing parts by realizing the jointing of Si chips and Cu members at a comparatively low temperature and reducing the residual stress.  
     CONSTITUTION: A Ti film 6 having a property of excellently bonding to Si is formed on the collector side surface of an Si wafer forming an element, and an Ni film 7 and a Cu film 8 are evaporated thereto. On the other hand, an Sn film 9 is formed on a Cu frame 2. The wafer is divided into chips, which are placed on the Cu frame 2 and welded in an N 2 +H 2  furnace at a temperature in the range of form 220W320°C to fabricate a Cu-Sn bond. Then, the bond is subjected to a sintering treatment for about 60 minutes at a temperature of 200°C to form a bronze alloy layer 10 at the jointing part between the Sin and Cu frames. According to this method, the residual stress is reduced to about 78% of the case of Pb-Sn series solder bond, and the cumulative proportion defective against the power cycle is remarkably improved and the life of the semiconductor is prolonged. Large-size chips of 3mm square or more can be joined to the Cu frame, and hence insertion of a Mo plate becomes unnecessary.

Abstract: PURPOSE: To miniaturize a preheating controller in which the control is made by detecting the temperature of a glow plug and as well to make the same lightweight, by energizing a constant electrical-current circuit for a short time necessary for detecting the temperature of the glow plug.  
     CONSTITUTION: A constant-current circuit 5 is energized for a time during which a condenser 36 is charged with electrical current passing through a resistor 37 when a key switch 1 is turned on, so that a constant electrical current is fed to a glow plug 14. If this energized time is set longer than the energized time of a sample hole circuit 7 which is determined by the time constants of a condenser 23, resistors 22, 35, a voltage held by the circuit 7 becomes irrespective of variations of the output voltage of an inversion amplifier circuit 6 accompanied with the completion of the energization of the constant-electrical current circuit 5, thereby the initial resistance value of the glow plug 4 is exactly sampled. About 0.2sec is sufficient for such as energized time, and therefore, its average power consumption is only less than about 0.5W so that heat radiating plates may be eliminated.

Abstract: PROBLEM TO BE SOLVED: To enhance machinability and reliability wile increasing light absorption of a semiconductor layer by employing polycrystalline thin film, where polycrystalline grains having an irregular surface are mixed with polycrystalline grains having a flat surface, on the surface of a polycrystalline thin film. SOLUTION: A transparent conductive layer 103 is disposed between a polycrystalline thin film 102 and a semiconductor layer 104 in the case of a photovoltaic element where the light impinges on the side opposite to a substrate 101 but disposed between a rear metal reflection layer 102 and the semiconductor layer 104 in the case of a photovolaic element where the light impinges on the substrate 101 side. The transparent conductive layer 103 may have a flat surface but when level differences, protrusions or recesses are formed depending on the polycrystalline grain boundary of the polycrystalline thin film 102, adhesion between the transparent conductive layer 103 and the semiconductor layer 104 is enhanced and the degree of freedom and the controllability of the fabrication process of photovoltaic element are enhanced furthermore.  Since scattering of light is accelerated on the interface between the transparent conductive layer 103 and the semiconductor layer 104, short circuit current is increased furthermore.
