Title: Semiconductor element mounting method
Inventor: NISHIGUCHI KATSUNORI
IPC: H01L23/40
Filed: 1990-11-20
Abstract: PURPOSE:To lower the thermal resistance by a method wherein the heat dissipation fins are bonded onto the rear surface on the opposite side of the surface of a plurality of semiconductor elements whereon bump electrodes are formed. CONSTITUTION:A heat sink 1 is bonded using AuSu, etc., onto the rear surface on the opposite of the surface whereon the bump electrodes formed into solder bumps semiconductor element 2 are arranged. Next, a plurality of elements 2 with their own electrodes aligned with one another are pressed down to be tack--fixed onto a wiring substrate 5 and then heated to melt down the bumps 4 for mounting the elements 2 on the substrate 5. Successively, a mold resin 6 is formed between the substrate 5, the elements 2 and the heat sinks 1 for the reinforcement of the whole body. Through these procedures, the heat sinks 1 and the elements 2 are previously bonded onto one another before the elements 2 are turned face-down on the substrate 5 so that the contact between the heat sinks 1 and the elements 2 may be assured so as to lower the thermal resistance.

Title: Digital filter
Inventor: SASAKI EISAKU
IPC: H03H17/06
Filed: 1990-11-20
Abstract: PURPOSE:To operate a circuit at a high speed and to reduce the circuit scale by performing the operation related to digits, whose value are '1' at the time of expressing the coefficient of each tap with a binary, in a multiplier of this tap. CONSTITUTION:Preliminarily determined tap coefficients C+n, C+n-1,... C1, C0, C-1,..., C-n+1, and C-n are given to multipliers 13+n, 13+n-1, 131, 14, 151, 15+n-1, and 15+n. Since these tap coefficients are fixed, each multiplier performs the operation with respect to only digits whose binary values are '1' out of digits of a multiplicand as the tap coefficient. The multiplier has a 4-bit full adder to which bit values A1, A2, A3, and A4 of respective digits of a multiplier are directly inputted. Since all bit values are directly inputted to the full adder in this manner, no AND circuits are used. The bit A0 is the sign bit. Since the multiplicand is fixed in this manner, logic circuits are not required at all. Since multipliers related to digits where the multiplicand expressed with a binary are '0' are '0', it is sufficient if the operation is performed with respect to only digits of '1'.

IPC: H05B37/02
Filed: 1996-11-26
Abstract: PROBLEM TO BE SOLVED: To avoid lighting interruption during operation of electronic equipment provided with a display unit even during input stoppage of an external brightness switching signal. SOLUTION: An MPU12 sends to an LED13 a light emitting diode drive voltage Vd according to a light quantity of an internal brightness switching signal Se that a photo-sensor 11 detects during supply stoppage of an external brightness switching signal Sb and turns ON the light. When a periphery is relatively bright the low light emitting diode drive voltage Vd is outputted, and when the periphery is extremely bright an output of the light emitting diode drive voltage Vd is stopped. As a result, even during input stoppage of the external brightness switching signal Sb, a light emitting quantity (brightness) of an LED13 is switched in the same way as the external brightness switching signal Sb without interrupting illumination of the display unit.

Title: Production of alc
Inventor: AONO YOSHIMICHI
IPC: C04B38/02
Filed: 1993-12-15
Abstract: PURPOSE:To produce an ALC panel excellent in a foamed state, remarkably reduced in the number of large air bubbles and having a remarkably uniform distribution of air bubbles by admixing a reducing agent with a slurry, kneading the resultant mixture, subsequently adding an aluminum powder coated with water glass, kneading the obtained mixture and then casting in a mold. CONSTITUTION:This method for production of ALV (high-temperature and high-pressure steam curing light-weight foamed concrete) is carried out by adding powdery aluminium as a foaming agent to a slurry containing a calcareous material composed of cement and lime, a siliceous raw material such as silica stone or silica sand and water as the main raw materials, kneading the resultant mixture and subsequently casting it into a mold. In the production method, a reducing agent is added to the slurry and the resultant mixture is kneaded. After adding an aluminium powder coated with water glass and kneading the obtained mixture, the kneaded material is cast into the mold. Ferrous sulfate or sodium sulfite is recommendably used as the reducing agent and the concentration or the amount is suitably controlled according to the reactivity of the powdery aluminium, the temperature of the raw material slurry, etc. Water glass forms a remarkably thin oxide coating film on the surface of aluminium and thereby aluminium can be prevented from reacting with an alkali.
