Patent JP-H08162561-A (JP)
Title: Semiconductor element package
Inventor: ITO NOBUYUKI
IPC: H05K3/34
Filed: 1994-12-08
Abstract: PURPOSE: To firmly and electrically connect electrodes of semiconductor integrated circuit elements with a specific external electrical circuit ranging for a long period by a method wherein a terminal having a spherical projection part is formed on a lower surface of an insulation base with non-eutectic solder. CONSTITUTION: A terminal 7 fitted on a connection pad 5 has a spherical projection part 7a, and when the terminal 7 is connected to a wiring conductor 8a of an external electrical circuit substrate 8, the spherical projection part 7a has such acts that the connection is facilitated and made sure. Further, since the terminal 7 is formed with non-eutectic solder, when the terminal 7 is heated and melted and connected with the wiring conductor 8a of the external electrical circuit substrate 8, the terminal 7 is simultaneously formed with a liquid phase and a solid phase, and the solid phase solder effectively prevents that liquid phase solder located in a recess 1b of an insulation base 1 is absorbed into the projection part 7a projecting on a lower surface of the insulation base 1.  Thus, each electrode of a semiconductor integrated circuit element 3 can firmly and electrically be connected to the external electric circuit.

Title: Method for detecting failure of air spring electronic control mechanism for rolling stock
Inventor: ISHIHARA KOICHIRO
IPC: B61F5/10
Filed: 1990-11-09
Abstract: PURPOSE:To improve the safety by controlling the feed and exhaust of each air spring according to the absolute value of the difference between the sums of the internal pressure of each air spring of front and rear trucks and a set differential pressure. CONSTITUTION:Only when the absolute value of the difference between the sums of internal pressures of air springs 1-4 situated on the diagonal line of a front truck 9 and a rear truck 10 is larger than a set differential value, feed valves 11-14 and exhaust valves 21-24 are opened and closed to control the internal pressure of each air spring 1-4 so as to be laid within a set target value. When the differential pressure is outside the target value, the difference between the sums of the internal pressures of the air springs 1-4 is judged, and the feed and exhaust of the air springs 1, 4 and the air springs 2, 3 are controlled so that the internal pressure is within the target value. When the inclination of a vehicle body is outside a set value, a control signal for feed and exhaust of the air springs 1-4 are outputted. Further, when the average height of the left and right air springs 1, 2, 3, 4 is outside a set average height, the feed and exhaust of the air springs 1-4 is controlled so that the height is within the set average height. Thus, the safety is improved.

Title: Sputtering device and collimator
Inventor: HIGUCHI MINORU
IPC: H01L21/203
Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To prevent the reduction in film thickness at the bottoms of deep holes on a semiconductor substrate without causing a varied film thickness distribution in the thickness of the film deposited on the substrate by distributing the opening diameters of the plural apertures formed on a collimator so as to extend toward the end from the central part of this collimator and maintaining the specified ratio of the opening diameters and opening depths. SOLUTION: The plural apertures are formed on the collimator 11 and the opening diameters thereof are smaller in the central part of the collimator 11 and large in the peripheral parts thereof. The ratios of the depths of the apertures to the opening diameters in the central part and peripheral part of the collimator 11 are both constant and are specified to 1 to 2. When sputtering is executed by installing such collimator 11, the deposition rate may be made uniform over the entire surface of the semiconductor substrate and the film thickness of the sputter particles deposited on the substrate are made uniform. The sputter particles hardly adhere to the flanks of the microholes formed on the semiconductor substrate and deposited uniformly on the bases, thereby making it possible to obtain the uniform film thickness.
