Filed: 2002-04-11
Abstract: <P>PROBLEM TO BE SOLVED: To provide a powder transporting method and regulation of high efficiency, capable of performing the compact next-generation image formation of high quality by accurately controlling the movement of powder with light load while saving a space.  <P>SOLUTION: A transporting electrode to which three-phase alternating current can be applied is formed on a dielectric such as glass with a width and a space of an electrode approximately same as that of the powder (toner), and the powder dispersed in insulating liquid carrier is transported by traveling wave field formed by three-phase alternating current. By applying the transportation by electric field, a transporting amount and a transporting speed can be accurately controlled, and the thinly-layered powder on a plane is suitable for the image formation (liquid development/ink jet). The insulating liquid stabilizes the charging of the transported powder, and realizes the stable transportation of powder for a long period.  <P>COPYRIGHT: (C)2004,JPO

Title: Method for manufacturing semiconductor laser element
Inventor: MIYAZAKI KEISUKE
IPC: H01S5/343
Filed: 2002-04-15
Abstract: <P>PROBLEM TO BE SOLVED: To form a semiconductor laser element having proper characteristics, by sequentially growing a plurality of semiconductor lasers on a single semiconductor substrate.  <P>SOLUTION: A method for manufacturing the semiconductor laser element comprises the steps of forming an AlGaAs semiconductor laser 29 on an N-type GaAs substrate 21; and then forming a non-doped GaAs protective layer 30. Thus, when the partial region of the laser 29 is removed by etching to expose the substrate 21, an impurity Zn is prevented from being vaporized from a P-type GaAs contact layer 28. Accordingly, it prevents the contact characteristics of a P-type electrode from being deteriorated due to the decrease in the carrier concentration of the layer 28. Further, it can prevent impurity vaporized from the layer 28 from readhering to the exposed substrate 21. Therefore, when the laser 28 is later formed, a layer in which the substrate 21 is mixed with the readhered impurity, it is not formed, and hence the reliability in the case of driving over a long period can be improved.  <P>COPYRIGHT: (C)2004,JPO

Title: Composite sintered bearing and method for manufacturing the same
Inventor: TAKEHANA TOSHIICHI
IPC: F16C33/14
Filed: 2002-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem concerning chips posed when a clearance portion (recess) is formed at the middle portion of the inside surface of a sintered bearing by machining, and also to solve the problem where the middle portion of the outer peripheral surface is also expanded and an after treatment becomes necessary to remove the expanded portion when the middle portion is expanded by plastic forming.  <P>SOLUTION: The sintered bearing is inserted into a sleeve which has a recess formed beforehand at the middle of its inner peripheral surface, and a core rod is inserted into the sintered bearing so as to penetrate the bearing. In this state, when the bearing is compressed from the upper and lower sides, the middle portion of the bearing expands, and the clearance portion (recess) is formed at the middle portion of the inside surface of the bearing. On the other hand, because the recess of the sleeve is filled with the expanded portion of the outer peripheral surface of the bearing, the sintered bearing is coated with the sleeve as a whole and a composite sintered bearing having no undulation on its outside surface is manufactured.  <P>COPYRIGHT: (C)2004,JPO
