Abstract: A probe replacement method for a scanning probe microscope for measuring the surface of a sample, having a cantilever (21) having a probe (20), and a measurement unit for measuring a physical quantity between the probe and sample. The scanning probe microscope is provided with a cantilever mount (22), a cantilever cassette (30), an XY stage (14) and Z stage (15) for moving the cantilever cassette, and an optical microscope (18). In a first step, a cantilever is selected from the cantilever cassette and is mounted on the cantilever mount. In a second step, an optical microscope is moved and the mounted cantilever is set in a prescribed position in the field of view after the cantilever is mounted in the scanning probe microscope. In the second step, a step is provided for moving the optical microscope side or the cantilever side and performing positional adjustment.

Abstract: A plasma display device which has sufficient levels of gradation for displaying a dark image, and a sufficiently low display luminance for a black level. A unit cell is composed of a large sub-cell 37 and a small sub-cell 38, and the luminance level of the small sub-cell 38 is set to 1/16, ?, ¼, or ½ from one sub-field to another, so that the gradation of a dark image is smoothly displayed. Also, since the light emission luminance is sufficiently reduced when black is displayed by producing a priming discharge in the small sub-cell 38, a satisfactory image is displayed.

Abstract: A plasma display device and its driving method are provided which are capable of displaying an excellent image, without an increase in costs caused by an increased number of driving circuits, by shortening a scanning period while writing discharge is made to occur with reliability and by improving contrast. In a plasma display panel (PDP) in the plasma display device, a group of unit cells is formed at intersecting points between each of groups of row electrodes and a group of column electrodes. Each of unit cells is made up of a display cell and auxiliary cell and is surrounded by a horizontal rib and a longitudinal rib. A horizontal communicating aperture is formed in the longitudinal rib to partition among two or more auxiliary cells and a longitudinal communicating aperture is formed in the horizontal rib to partition between the display cell and auxiliary cell both being arranged in the column direction.

Abstract: In a plasma display panel, cells are disposed in a column direction and in a row direction in the form of a matrix, and electrodes are formed such that, in cells located in each column, a cell has a priming electrode (auxiliary electrode) electrically connected via an interconnection to a scan electrode of a cell at an upper adjacent location. This structure in terms of electrodes allows a write discharge to occur without fail in a reduced scanning period.

Abstract: A method of driving an ac-discharge type PDP is provided, which expands the permissible range of the voltage applied across the scan and data electrodes at writing discharge and which ensures desired writing discharge generation even if the writing voltage has a comparatively small amplitude. First, (a) a wall-charge adjustment step of storing first wall-charge of a first polarity near the respective scan electrodes and second wall-charge of a second polarity near the respective sustain electrodes is performed, where the second polarity is opposite to the first polarity. The first wall-charge of the first polarity stored near the respective scan electrodes generates an associate electric-field in the cells. The step (a) is performed by common application of at least one of a first wall-charge adjustment voltage pulse to the scan electrodes and a second wall-charge adjustment voltage pulse to the sustain electrodes.

Abstract: In a plasma display panel, data electrodes are formed parallel to each other on a first substrate, and a selection voltage is to be applied to them. A dielectric layer covers a surface of the first substrate to include the data electrodes. Linear partitions are formed at a predetermined interval on the first substrate to be parallel to the data electrodes. A second substrate opposes the first substrate. A closed space between the first and second substrates is filled with a gas. Intersections of a pair of sustain discharge electrodes and data electrodes form matrix-like discharge cells. Stepped partitions are formed at a predetermined interval on the first substrate in a direction intersecting the linear partitions.

Abstract: A still picture reproducing system for a magnetic recording and reproducing apparatus is disclosed. The system sends one frame in order to shift a reproduction mode from ordinary reproduction to reproduction of a still picture by use of so-called "fine slow", sends one more frame if a noise is detected on a picture at this time, and stops if no noise is detected.
