A process control apparatus for controlling a control target includes, but is not limited to, first and second control units. The first control unit is designed in a design environment unspecifying any period of disturbance. The first control unit performs a feedback control to the control target by using a setting value of the control target and a measured value of the control target. The first control unit is included in a feedback loop. The second control unit is also included in the feedback loop. The second control unit is designed by using an internal model principle. The second control unit rejects the disturbance, which is applied to the feedback loop, by using the measured value of the control target.

A plasma display panel has a first plate and a second plate facing each other via a discharge space. A plurality of first electrodes and a plurality of second electrodes extending in a first direction, and a plurality of address electrodes extending in a second direction intersecting with the first direction are provided at the first plate. Also, a plurality of first barrier ribs extending in the second direction are integrally formed with the second plate at the first plate side of the second plate. Further, the plasma display panel has, for example, an antireflective film formed on a surface of the second plate at an opposite side of a surface facing the first plate. As a result, a contrast of an image can be improved.

The present invention relates to an optical fiber which has a structure for further increasing an FOM (=|dispersion|/loss) and which can be applied to a dispersion compensation module. The optical fiber is mainly composed of silica glass and has a core region including a center of an optical axis, a depressed region surrounding the core region, a ring region surrounding the depressed region, and a cladding region surrounding the ring region and doped with F. As compared with the refractive index of pure silica glass, a relative refractive index difference of the core region is greater than 2% but less than 3%, a relative refractive index difference of the depressed region is −1% or more but −0.5% or less, a relative refractive index difference of the ring region is 0.01% or more but 0.24% or less, and a relative refractive index difference of the cladding region is −0.3% or more but −0.1% or less. The FOM at the wavelength of 1550 nm is 250 ps/nm/dB or more.

A knee-protecting airbag apparatus is mountable on a door of a glove box that has a box body provided with an opening at the rear and the door. The airbag apparatus includes an airbag, a generally columnar inflator housed in the airbag, a case housing the airbag and inflator, and an airbag cover constituting a rear face of the glove box door and being openable at airbag deployment. The inflator includes a body that discharges inflation gas and a fixing section that secures the body and the airbag to the case. The fixing section includes a projecting portion and the projecting portion extends at an upward or downward angle to the thickness direction of the glove box door.

A plasma display panel includes a first and a second panel. The first panel includes a first plate provided with a plurality of display electrodes extending in a first direction. The second panel includes a second plate facing the first plate via a discharge space, a plurality of first barrier ribs provided on the second plate, and a dent part opened to a side of the first plate. The dent part is provided in between the barrier ribs adjacent to each other. A width of the dent part along the first direction is formed to be narrower toward a side of the second plate from the side of the first plate for at least within a range from a position at a half of a depth to a bottom part of the dent part. As a result, a luminescent efficiency of the PDP can be improved.

A power steering apparatus includes a steering shaft, a hydraulic power cylinder, a hydraulic pump, a steering shaft actuator, a condition sensor, and a fluid pressure controller. The steering shaft is connected to a steering wheel. The hydraulic power cylinder is mechanically linked to the steering shaft. The hydraulic power cylinder has first and second fluid pressure chambers for producing an assist steering effort. The hydraulic pump supplies a first fluid pressure to the hydraulic power cylinder. The steering shaft actuator receives a second fluid pressure from the hydraulic pump, and applies a torque to the steering shaft by the second fluid pressure. The condition sensor collects information concerning at least one of an associated host vehicle, an associated driver and an associated road. The fluid pressure controller receives the collected information from the condition sensor, and controls the steering shaft actuator based on the collected information.

An image display unit has a display region with a higher resolution than a number of pixels of an image. A base information storage unit stores viewing position information of a viewer and size information of the display region. A wide-angle transformation unit calculates a central area including a viewing center of the viewer of the display region using the viewing position information and the size information, divides the image into a first pixel area corresponding to the central area and a second pixel area corresponding to a peripheral area other than the central area, and transforms the first pixel area and the second pixel area by magnifying. A magnification ratio of the first pixel area is less than a magnification ratio of the second pixel area. The image display unit displays an image including the transformed first pixel area and the transformed second pixel area.

In conventional plasma display devices, reset by obtuse waves has been performed since discharge intensity becomes higher and background light emission is increased when reset by rectangular waves is performed. However, further improvement of the contrast to improve the image quality has been demanded. The present invention provides a driving method of a plasma display device using obtuse-wave reset in which sustain time of an achieved potential of the obtuse-wave reset is controlled in accordance with a display ratio of a video signal.
