Title: Soldering method
Inventor: KAWASAKI KAZUE
IPC: H01L21/52
Filed: 1997-12-17
Abstract: PROBLEM TO BE SOLVED: To avoid an oxide film by heating a solder layer composed of laminated solder materials different in m.p., pressing it with specified pressure to react a part of molten solder materials with the max. m.p. solder material to alloy and pressing connections of the materials with a larger pressure than the specified just before the alloying ends. SOLUTION: Heating a solder layer 26 composed of laminated Sn and Au layers 25, 24 starts. When the temp. Q1 of the solder layer 26 exceeds the m.p. of the Sn layer 15 at time T2, the Sn layer 25 melts and reacts with the Au layer 24 to form an Sn-Au alloy. According to this reaction, a semiconductor substrate 21 is held and pressed to the Au layer 24 at specified pressure 33 at time T3, thus tacking just before these alloy reactions end. When the temp. rises more the Au and Sn layers 24, 25 entirely react to form an Sn-Au alloy layer 28 at time T4, it is pressed to the alloy layer 28 at specified pressing force 34 to react connections 23 of semiconductor elements 21 to the Au alloy 28, thus ending the bonding.

Title: Device for adjusting antenna direction
Inventor: OKAZAKI YASUHIRO
IPC: H01Q3/08
Filed: 1992-12-25
Abstract: PURPOSE:To recatch a satellite with a dielectric electrostatic sensor even when radio wave is interrupted with a building or in a tunnel and to fix the sensor directly to the back of an antenna by using the sensor as an inclination detecting means. CONSTITUTION:The dielectric electrostatic sensor to be an inclination sensor 10 for detecting the change on the surface of a dielectric solution in a metallic chamber due to inclination as a change in electrostatic capacity is a compact sensor with high shock resistance since there are no moving parts and the sensor acts also as an acceleration sensor in an inclination measuring direction. Since the sensor 10 is compact and light-weight, the sensor 10 is appropriate for being fixed to the back of the antenna 1. Torque proportional to voltage corresponding to a difference between an inclination detected by the sensor 10 and a previously determined reference elevation angle for the satellite is generated and an elevation angle driving motor is excited, so that the inclination of a bracket 2 is corrected and the bracket 2 can be made stationary at a prescribed angle.

IPC: C02F3/06
Filed: 1997-12-18
Abstract: PROBLEM TO BE SOLVED: To facilitate excellent operation for a long term by arranging a plurality of waste water treating parts consisting of a microorganism carrier in successive stages, and by attachably and detachably constituting basic unit structure parts consisting of the waste water treating part. SOLUTION: Heaters installed around containers 12 and 32 control the temperature in first and second treating tanks 10 and 30 at 20 deg.C to 40 deg.C to sufficiently maintain the activity of microorganisms. Because organic waste water is treated in the second treating tank 30, it is feared that sludge collects in treatment layers 34a-34d and first auxiliary layers 36a-36d. Especially, the collection of the sludge in the treatment layers 34a-34d deteriorates ventilation to effect bad influences such as the decrease of the activity of the microorganisms.  Since a pair of the treatment layer 34 and the first auxiliary layer 36 are constituted as a basic unit structure part, that is, a pack, to be attachable and detachable, long-term operation in a good condition can be easily achieved by exchanging the pack consisting of a pair of the treatment layer 34 and the first auxiliary layer 36, or the like.
