When the stirring means has the rotary shaft nearly in the horizontal direction with respect to the gravitational direction, the dispersion medium is uniformly distributed and dispersion intensity is constant regardless of a place.  Therefore, the dispersion liquid obtained by this producing method has uniform dispersion and the variation of the dispersed state of every dispersion lot is small.

Title: Strain removing method of outside plate having oxide film
Inventor: FUKUYORI KAZUNARI
IPC: B21D1/06
Filed: 1978-06-26
Abstract: PURPOSE: To remove strain efficiently without damaging surfaces with heating flames by using an arc heat source by opposite polarity current or AC current having cleaning action for the heating surce and heating and cooling the strain portions of outside plates at the time of removing the strain of the outside plates such as of Al alloy or other having oxide films.  
     CONSTITUTION: Opposite polarity current or AC current is flowed to the electrode 3 in the nozzle 4 of a heating torch body 2 from a power source 7, whereby a heating arc flame 6 is produced under the flow of shielding gas 5. A vehicle outside plate 1 made of Al alloy having oxide films is heated by this arc flame 6, then electrons are produced from the oxide film portions and break down the oxide films, thereby creating cleaning action to provide a silver white color. The cleaning area 11 is evenly heated by the heating arc flame 6 owing to this action and melts down in the heating area 12 of the outside plate 1, thus production of any pockmarks and the like is obviated. This heating causes the outside plate 1 to be shrank and be given tension, thus accomplishing strain removing of the outside plate 1.

Title: Cross-linked emitter-doped silicide transistor
Inventor: MAJIYUKAARU BII BORA
IPC: H01L27/082
Filed: 1990-03-28
Abstract: PURPOSE: To create a bipolar transistor with a minimum effective area by forming a contact with an extrinsic base region by a bridge made of doped metallic silicide. CONSTITUTION: A region 12 gives a contact with a collector 15, a region 21 functions as a base and a region 40 serves as a base contact. A region 43 is an emitter in contact by emitter contacts 25/28 and the base contact 40 is connected by an electrode 38. Since a silicon dioxide layer 30 isolating the base contact 38 from an emitter contact silicide 28 is removed before the deposition of the base contact, the contact 38 is short-circuited to the contact 28, and hence, the emitter of one transistor is connected to the base of another transistor. Thus, a bipolar transistor with a minimum effective area is manufactured.
