Title: Method for washing bipolar semiconductor wafer
Inventor: SABURI ARATSUKU
IPC: H01L21/311
Filed: 1988-01-14
Abstract: PURPOSE:To lower the voltage between a base and an emitter by a method wherein the wet etching to be used to attack a B-Si-O-F phase only is included. CONSTITUTION:A silicon wafer is etched by a wet etchant with which B-Si-O-F phase only is attacked. Then after said etching is finished, the silicon wafer is put in a metal adhering stage within 15 minutes. To be more precise, the B-Si-O located at the contact point of a base is removed by the first etching. The fluorine beneath a boron film is removed by annealing. The B-Si-O-F phase left from the annealing stage is removed by the final etching. As a result, a bipolar semiconductor device of low voltage Vbe between the base and the emitter can be obtained.

Title: Improved starter for rotor of permanent magnet synchronous motor and centrifugal pump containing it
Inventor: MARIONI ELIO
IPC: H02K1/27
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To prevent the rotor and motion transmission from touching a caustic alkali solution or other active solution by containing them in a hermetically sealed space. SOLUTION: A rotor unit 23 includes a cylindrical cap-shaped element 24 closed hermetically by a cover 25 and firmly coupled with a shaft 19 directly or through the cover 25. A permanent magnet rotor 29 is housed rotatably in the cap-shaped element 24 where the rotor 29 rotated freely with respect to the shaft 19 and a motion transmission means is disposed between the rotor 29 and the shaft 19.

IPC: H01L39/24
Filed: 1988-01-19
Abstract: PURPOSE:To obtain the title film of increased orientation by forming a film of superconducting oxide composition (except oxygen) on a substrate followed by two-step heat treatment in atmospheres with oxygen partial pressures specified respectively.
