Title: Cast metal seal for semiconductor substrate
Inventor: JAMES HOWARD COVELL II
IPC: H01L23/10
Filed: 1998-04-20
Abstract: PROBLEM TO BE SOLVED: To enable a semiconductor substrate to be hermetically sealed up in a cap whose thermal expansion coefficient is different from that of the substrate by a method wherein a first thin solder interconnection layer is restrained from reflowing on a high-melting thick solder wall so as to enable a solder seal band to retain its layered structure. SOLUTION: A solder seal 23 is joined to a substrate 10 with a thin solder interconnection layer 41 formed on the substrate 10 and a thick solder wall 43 cast on a cap 20. The thick solder wall 43 is set different in chemical composition from the thin solder interconnection layer 41 so as to have a higher melting point than the thin solder interconnection layer 41. By this setup, the interconnection layer 41 can be reflowed so as to mount the cap 20 on the substrate 10 without melting or deflecting the thick wall 43. Therefore, a solder seal of this constitution is capable of coping with a case that a gap between a cap and a substrate is a few times as large as usual.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To provide a fluid transfer device used in wide areas even if the properties of the fluid such as liquid, gas, and their mixture and contaminants are different from each other. SOLUTION: A device operates a primary pump 2 so as to supply working fluid to a box 1, which maintains a tightness and has a specified rigidity, through a pipeline 3 to which a selector valve 4 is connected, pressurizes the box 1 to a positive pressure, contracts a flexible bag 5 of a secondary pump 10 installed in the box 1, and feeds the fluid inside the bag 5 through a check valve 9 connected to an outlet pipe 7. Next the selector valve 4 is selected so as to discharge the working fluid to the outside of the box 1, reduces the pressure inside the box 1 to a negative pressure so as to expand the bag 5, and leads the fluid to the bag 5 through a check valve 8 connected to an inlet pipe 6.  Hereafter, the operation of the primary pump 2 and the selection of the selector valve 4 are repeated so as to feed the fluid intermittently by a fixed volume for feeding of multiple types of fluid.

Title: Direct-current voltage power pack
Inventor: HUBERT ROLF
IPC: G06F1/30
Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To avoide a wrong information due to a short-time voltage abnormality of an external supply power voltage by reading a signal input side with a computing unit depending upon an additional signal state and depending upon the presence of an unbuffered detected input voltage. SOLUTION: A detecting means 22 for detecting an unbuffered supply power voltage Uext is constituted as a comparator 22 which compares the external voltage Uext with a predetermined threshold U-Schwell. The comparator 22 generates a signal DC-LOW in every case of voltage abnormality. When a wrong count result is supplied in the case of counter switching obtained by a programmable control part, the additional signal DC-LOW is generated depending upon the state of the unbuffered external supply voltage and transferred to a computing unit μC so that the signal input side is made not to be read in. Only in normal monitoring state, the signal input side is made to be read out.

Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To provide a control method for a three-dimensional measuring machine capable of measuring the shape of three-dimensional objects such as machined goods and molded goods accurately despite of reduction of the number of measuring points. SOLUTION: A computer gains polygon data specifying the shape of a three- dimensional object. The measuring point of the three-dimensional measuring machine is set at the top 32 of the polygon expressed by the polygon data. In the polygon data, estrangement between each side 33 of the polygon and the three-dimensional object surface 34 is surely limited in a tolerance (t). As the results, a large polygon is formed on a surface with large curvature and a small polygon is formed on a surface with small curvature. Therefore, three- dimensional coordinate values of a three-dimensional object surface can be obtained at an interval with specified accuracy.

Abstract: PURPOSE: To identify a mirror pellet by subjecting the reflected light from each pellet to thresholding image recognition using two kinds of luminance threshold values, detecting the pellet size and the mark size and then deciding whether the pellet is acceptable or rejectable. CONSTITUTION: In the pellet identification method for a die bonding process, the quantity of illumination light, the luminance threshold values I, II and mark size threshold values I, II are set at first (S101). The profile and position of the pellet are then detected using the luminance threshold values 1 and a mark size detected using the luminance threshold values 1 is compared with the mark size threshold value 1. It is decided that no fail mark is present if the detected mark size is smaller than the mark size threshold value I (S101, 103). It is decided that a pellet is acceptable if a mark size detected using the luminance threshold value II is larger than the mark size threshold values II (S104). Subsequently, an acceptable pellet is die bonded (S105) and the decision is completed for all pellets on one wafer (S106).

Abstract: PURPOSE:To transport a sheet member efficiently and smoothly by installing an amplifying transmission member which amplifies transmits vibration in the form of the longitudinal vibration onto the sheet. CONSTITUTION:A vibrating piece 18 is constituted integrally with a metal block 14 on the edge surface of a vibrating transport part 1, and forms a plate-shaped cantilever form, and is designed to generate a resonance state with the frequency equal or nearly equal to the resonance frequency of a longitudinal vibration element.

The vibrating transport part 1 performs transport by applying the contact pressing onto a sheet- shaped member 3 which is to be transported on a sheet supporting body 4 and applying the vibration of the vibrating piece 18 onto the sheet-shaped member 3. Transport is carried out by the projection action of the vibrating piece 18 onto the vibrating member. In the vibration state of the vibrating piece 18, a reciprocating vibration which is formed by synthesizing the longitudinal vibration of the vibrating element and the deflection vibration of the vibrating piece 18 is generated, since the vibrating element 18 is inclined by 90 deg. for the center axis (a) of the vibrating transport part.
