Title: Self-correcting semiconductor memory
Inventor: YAMADA JUNZO
IPC: G11C29/42
Filed: 1986-04-21
Abstract: PURPOSE:To reduce the size of the scale of an additional circuit and to improve the yield by controlling a selecting switch so that neighboring groups of memory cells and neighboring groups of inspection cells do not belong to the same horizontal/vertical group. CONSTITUTION:Cell information are selected by a horizontal group selecting switch 10' and a vertical group selecting switch 11' and respectively transmitted to nodes N12-N15 and N16-N19. Thereafter, exclusive OR gates EOR 2 and EOR 3 execute a horizontal/vertical group parity check, and by means of a resulting combination, the data from the output node N23 of a multiplexer 7 is corrected and supplied to an output terminal. In such a constitution only three pieces of two-input EOR circuits are respectively needed, and the size of the scale of an additional circuit can be reduced. This allows that an excess word line is added to facilitate the defect-remedy for a word line, and thus the yield is improved.

Title: Coextruded laminating material excellent in oxygen barrier property and production of laminating material thereof
Inventor: KATO TAKEO
IPC: B32B27/28
Filed: 1989-04-12
Abstract: PURPOSE:To obtain the coextruded laminating material which is excellent in oxygen barrier property and capable of long-term preservation of the contents by laminating both a resin layer which has oxygen barrier property and consists of the saponified material (EVOH) of an ethylene-vinyl acetate copolymer and a specified polyester resin layer by coextrusion. CONSTITUTION:The coextrusion laminating material of EVOH is produced by laminating both a resin layer having oxygen barrier property which consists of at least EVOH and a polyester resin layer having 0.75 - 0.90 intrinsic viscosity (I.V.) by coextrusion. EVOH incorporating 20 - 60mol.% ethylene and having >=96% degree of saponification and 0.15 - 1.5 (cc.20mum/m<2>.day.atm) oxygen permeability is preferably utilized. When I.V. of polyester resin is value exceeding 0.9, polyester resin shows high viscosity at the temp. lower than 260 deg.C and thereby the motor of an extruder is overloaded. Therefore polyester resin is necessarily extruded at the temp. higher than 260 deg.C. Accordingly EVOH is allowed to gel. Further when I.V. is value smaller than 0.75, polyester resin shows low viscosity and thereby control of thickness of extruded polyester resin film is made difficult and film formability is deteriorated.

Title: Method for evaluating life of soldering connection of electronic component
Inventor: SATO RYOHEI
IPC: H01L21/60
Filed: 1990-04-10
Abstract: PURPOSE:To accurately evaluate the life by finding a cracking progress speed expression showing the relation between a cracking progress speed and an equivalent strain amplitude and a life evaluation reference expression indicating the relation among the equivalent strain amplitude, the length of cracking, and the number of life cycles. CONSTITUTION:A semiconductor integrated circuit 1 and a circuit board 2 differ in coefficient of thermal expansion, so when temperature variation is caused repeatedly or the circuit is powered on and off repeatedly, connection part solder 3 is strained to have a crack 4. This crack 4 extends by an interval da/dN (at cracking length, N the number of cycles) in each cycle. This interval da/dN is called as the cracking progress speed. This cracking progress speed can be approximated in linear relation da/dN=Ad+B (A and B: constant) to the cracking length (a). This equation is integrated to obtain a life evaluation equation N=(1/A)log¦(Aa+B)/(Aa0+B)¦ and a life evaluation chrt. Consequently, the number of cycles as the life is found from the cracking length (af) which is a life reference.
