Title: Motor driving and controlling device
Inventor: YOKOI YUJI
IPC: H02P6/12
Filed: 2005-01-14
Abstract: <P>PROBLEM TO BE SOLVED: To stop an object to be driven by a motor in a short time even in power failure without increase in the number of components, even though the motor does not have a speed reducing mechanism.  <P>SOLUTION: A motor driving and controlling device is for driving and controlling a DC brushless motor 5 having three-phase windings 8 and rotor permanent magnets 7. The device includes a power supply; an inverter circuit 4 connected between the power supply and the DC brushless motor 5; a power failure detection circuit 15 that detects power failure; and a computer 10 that, when power failure is detected by the power failure detection circuit 15, controls the inverter circuit 4 to short-circuit the winding terminals of the DC brushless motor. In power failure, the rotational energy of the DC brushless motor 5 is damped by dynamic braking through the winding resistance of the three-phase windings 8 and the rotor permanent magnets 7 of the DC brushless motor 5 within a time range for which control can be carried out with remaining electricity.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Light scattering type display element
Inventor: TODA ATSUSHI
IPC: G02F1/1335
Filed: 2005-01-19
Abstract: <P>PROBLEM TO BE SOLVED: To heighten a contrast ratio of a light scattering type display element compared with a conventional one by heightening only a reflectance in white display without heightening a reflectance in black display.  <P>SOLUTION: A projecting and recessing layer 22 is laminated on the uppermost surface of a display side substrate portion 2, and a projecting and recessing shaped portion 23 is formed on the surface. The projecting and recessing shaped portion 23 has slopes inclined toward a substrate surface and a light incident surface. A plurality of projecting and recessing shaped portions 23 are formed for each pixel. Due to the fact that the uppermost surface of the display side substrate portion 2 is formed to have a projecting and recessing structure with the slopes, internal reflection is reduced compared with the case of a flat uppermost surface, and, in the white display state, the ratio of light returning to the liquid crystal layer 30 side is reduced. The surface structure of the projecting and recessing layer 22 is not restricted to a curved surface (a spherical surface) with a perfect circle cross section, but is possibly a curved surface recognized as a recessing surface seen from the observer's side. For example, the cross section is optionally an elliptic curved surface, or further a distorted elliptic curved surface.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Insulated-gate semiconductor device and manufacturing method thereof
Inventor: OTSUKI MASATO
IPC: H01L29/78
Filed: 2005-01-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device and a manufacturing method thereof wherein switching loss is lowered, turn-on characteristic is improved, and higher dielectric strength is obtained while lower on-voltage is kept in the trench IGBT.  <P>SOLUTION: Potential of mesa region is fixed by connecting it to an emitter electrode so that the mesa region held by the trenches is freed from a floating structure. Switching loss is lowered and total loss generated can also be lowered, while the on-voltage of the trench type IGBT is kept as low as that of the IEGT by dividing the mesa region held by the trenches into a plurality of p-type base regions and forming the restricted region in the mesa region as the emitter structure. In addition, since the region is reduced where the gate electrode is facing to the emitter structure, a gate-to-emitter capacitance can be reduced. Higher dielectric strength can be attained by alleviating concentration of field to the bottom part of trench gate by adequately arranging the trench gate structure having the interval which is narrower at a certain degree. The n-layer of the mesa region held with the trench gates can easily be depleted by voltage application of several volts or so by narrowing the width of the mesa region held by the trenches.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
