Title: Method for forming pure cu build-up layer on iron alloy base material
Inventor: KAWASAKI MINORU
IPC: B23K26/34
Filed: 1990-04-06
Abstract: PURPOSE:To form a pure Cu build-up layer on a build-up auxiliary metal solidified layer by placing mixed powder of pure Cu powder and build-up auxiliary metallic powder of a specific condition on an iron alloy base material and melting them by a high density energy source. CONSTITUTION:At the time of forming a pure Cu build-up layer 34 on an iron alloy base material 10, mixed powder of pure Cu powder and build-up auxiliary metallic powder whose melting point is higher than that of the pure Cu powder, whose Ni content is <=16wt.% is placed on the iron alloy base material 10 and melted by a high density energy source. In this case, a build-up auxiliary metal in a molten metal starts its solidification preferentially, comparing with pure Cu since its melting point is higher than that of pure Cu. Also, a solidified layer 30 of the build-up auxiliary metal is formed on the base material 10. Thereafter, residual Cu is solidified 32 on the solidified layer 30 of the build-up auxiliary metal. Also, it is avoided that purity of the Cu layer 32 is deteriorated due to a fact that Ni is mixed into the Cu layer 32.

IPC: H01L21/322
Filed: 1991-03-29
Abstract: PURPOSE:To reduce the warp of a wafer by forming a groove in a polysilicon film which has been applied to the rear of the wafer. CONSTITUTION:A polysilicon film 2 which has been applied to the rear is formed in order to keep the surface of a silicon wafer 1 clean by taking in metal impurities as a cause of deteriorating the characteristic of a device when the device is formed on the wafer. As the device is formed and, consequently, as it is oxidized and etched repeatedly, polysilicon is reduced at the semiconductor wafer 1. When the film is removed, its effect to take in the metal impurities disappears. When the polysilicon film 2 applied to the rear is made thick, the wafer 1 is warped. When grooves 4 are formed in the polysilicon film 2 on the rear of the wafer 1, a stress is eliminated at the groove parts and the warp of the wafer 1 is reduced.

Title: Method for determining surface finish of small fragile material by bending test
Inventor: KOGA MASAKI
IPC: G01N3/20
Filed: 1993-04-21
Abstract: PURPOSE:To easily determine a surface finished state of a small fragile material such as a crystal vibrator substrate (blank) by performing a bending test of the small fragile material and plotting results on a Weibull probability paper. CONSTITUTION:A three-point bending test of a blank is performed. A sample size of the test is a thickness of 1mm or less wherein a distance between fulcrums for the threepoint bending is 20mm or less. In the case of the same destruction mechanism, measurement is made on numerous points and results are plotted on a Weibull probability paper, whereby a single line can display failure probability. On the other hand if different destruction mechanisms are mixed, the results are not plotted by a single line, so that a bending destruction mechanism of the blank can be identified by using the Weibull probability paper, allowing problems on machining to be captured. Machining accuracy of the blank surface finish can be statistically determined from a position and inclination of the line.

Title: Digital voltage balance relay
Inventor: SATO CHIKAO
IPC: H02H3/28
Filed: 1991-03-29
Abstract: PURPOSE:To obtain a voltage balance relay the sensitivity of which is not lowered even at a low frequency by using two kinds of AC voltages sampled at regular time intervals, obtaining quantities corresponding to each voltage by performing addition on absolute values of sampled values during a half-wave period or a period which is as long as an integer multiple of the half-wave period, and discriminating as unbalanced when the difference between the two quantities exceeds a fixed value. CONSTITUTION:Introduced AC voltages V1 and V2 are converted into digital quantities through an A/D-converting section 2 after the voltages V1 and V2 are sampled at regular periods. A central arithmetic section 3 obtains two quantities proportional to each voltage by performing addition on the absolute values of the samples during a half-wave period or a period which is as long as an integer multiple of the half-wave period. Then the section 3 detects an unbalance between the two voltage V1 and V2 by detecting that one quantity becomes lower than a fixed value by using the other quantity as a reference and outputs it from an output 6. Therefore, a digital voltage balance relay the sensitivity of which is not lowered even at a low frequency can be obtained.
