Title: Terminal connecting structure for semiconductor
Inventor: ANDO MASARU
IPC: H01L23/50
Filed: 1985-04-24
Abstract: PURPOSE:To obtain a terminal connecting structure having high reliability by floating a soldering section for a Cu terminal from an AlN substrate and soldering the soldering section. CONSTITUTION:Al2O3 powder is suspended into nitrocellulose, thus preparing a liquid having predetermined viscosity. Soldering execution positions 1 for the AlN substrate 6 are masked, and a suspension is printed only where corresponding to a Cu pattern 2, and also printed on the back. Tough pitch copper in thickness of approximately 300mum is placed and heated at a temperature where the hypo-eutectic region of Cu is kept in an inactive atmosphere, and cooled, thus manufacturing CuO2 on an Al2O3 layer 5. The AlN substrate 6 holding an air gap 4 is arranged oppositely to a Cu layer 3 in which there is no Al2O3 5. An external terminal 8 is soldered 7 to the Cu layer in the upper section of the air gap 4, a semiconductor element is fixed to the conductive pattern 2 consisting of CuO to form an assembly, and the terminal 6 is projected and sealed with a resin. According to the constitution, stress due to the difference of thermal expansion coefficients is absorbed, thus preventing the generation of a substrate crack or cleavage and the peeling of the Cu pattern.

Title: Lowering in aluminum concn. in galvanizing bath
Inventor: MIYASAKA AKIHIRO
IPC: C23C2/06
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To easily and rapidly lower the aluminum concn. in a galvanizing bath by bringing the aluminum in this galvanizing bath into reaction with an oxide having a standard forming free energy at a specific temp. ion a specific range, thereby converting the aluminum to aluminum oxide and removing the same. SOLUTION: The aluminum in the galvanizing bath is brought into reaction with the oxide of >=-900 to <=-550 jJ/mol in the standard forming free energy ΔG at 450 deg.C, by which the aluminum is converted to the aluminum oxide. This aluminum oxide is floated on the surface of the molten zinc bath and is removed. If the standard forming free energy ΔG at 40 deg.C of the oxide is below -900 jJ/mol, the oxidation reaction of the aluminum in the molten zinc bath does not sufficiently progress and the removal efficiency of the aluminum is low. If the energy is over -550 jJ/mol, the ratio at which the zinc is oxidized in addition to the aluminum increases and, therefore, the loss of the zinc increases. The oxide is preferably zinc oxide, titanium oxide, silicon oxide and boron oxide.

Patent JP-S5136039-A (JP)
Inventor: DAGURASU SHII BOSUN
IPC: G06F12/16
Filed: 1975-07-17
Abstract: This specification describes an error correction system for a high density memory made up of a number of monolithic wafers each containing a plurality of arrays that are addressed thru circuitry and wiring contained on that wafer. The storage bits on the wafers are functionally divided into a number of blocks each containing a plurality of words. The words of each block are on several wafers with each word made up of a plurality of arrays on a single array wafer. Each word in a block is protected by a similar error correction double multiple error detection code. The block is further protected by two additional check words made up using a b-adjacent code. Each byte in the check words protects one byte position of the words of the block. When a single error is detected in any word by the SEC-MED code the code corrects the error. If a multiple error is detected, the multiple error signal points to the word in error to be corrected by the b-adjacent code check words.

Title: Discrimination device
Inventor: FUJITA HAJIME
IPC: G06Q10/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To decrease the possibility that a personal identification number is read by a third person by making an identification number for collation changeable when an operating person inputs an unchanged previous identification number. SOLUTION: An identification number memory 33 stores an identification number as a collation identification number when the number is input from a controller 31. A controller 11 outputs a 10-second count start signal to a timer 32 when a change mode selection signal is input from a mode selection part 21. When an identification number is input from an identification number input part 22, the controller collates the collation number stored in the memory 33 and when both numbers coincide with each other, the controller is brought to a standby condition for inputting a changing identification number and a 10-second count start signal is output again to the timer 32. When the identification number is input from the input part 22, while the controller is in a standby condition for inputting the changing identification number the number is output to the memory 33.  In this way, an identification number can be changed.
