Abstract:
One field is formed of a plurality of sub-fields, and each one of the sub-fields includes an initializing period, addressing period, and sustained period. The sub-field is one of an entire-cell initialization sub-field or a selective-cell initialization sub-field. When the entire initialization sub-field is switched to the selective one or vice versa, an initializing voltage which generates initializing discharge in the entire initialization sub-field is controlled. This control allows varying the number of the entire initializations and stabilizing address discharge in a plasma display panel, and at the same time, making the black luminance inconspicuous for improving the picture quality.

Bioassay equipment which prevents a variation in concentration of a medium or deposition/bonding of a substance in the medium to be caused by drying of the medium being stored or held in a reaction region providing an inter-substance interaction field. The bioassay equipment (2) comprises at least a means for supplying a medium containing a substance pertaining to the interaction to the reaction region R providing the field of inter-substance interaction such as hybridization, and a means for supplying required water automatically. The bioassay equipment (2) may comprises a means for automatically detecting the volume of the medium held in the reaction region R.
Abstract:
One field period includes at least one subfield (SF) group made of at least two successive SFs. In the SF group, in the SF subsequent to a SF in which no sustaining discharge is caused, writing discharge is controlled to cause no sustaining discharge. One of all-cell initializing operation and selective initializing operation to be performed in the initializing period in the top SF of the SF group is determined depending on a signal of an image to be displayed. In the top SF of the SF group, the period allocated to the writing discharge in the case of the selective initializing operation is set longer than the period allocated to the writing discharge in the case of the all-cell initializing operation. This structure provides a plasma display panel and a driving method thereof capable of inhibiting increases in black picture level and displaying images at excellent quality.
Abstract:
An information recording and/or reproducing apparatus includes a laser light source from which a laser beam having a wavelength of from 220 nm to 280 nm exits; and a converging lens unit disposed at a nearfield area of a recording medium and upon which the laser beam from the laser light source is incident. The converging lens unit includes an objective lens and a solid immersion lens. The solid immersion lens is disposed between the objective lens and the recording medium, and is formed of a highly refractive material having a high transmittance. The information recording and/or reproducing apparatus records an information signal onto or reproduces an information signal from the recording medium by irradiating the recording medium with the laser beam from the laser light source.
Abstract:
One object of the present invention is to provide means for readily attaining a large scale cultivation of sphagnum moss under various conditions, in other words, means for establishing a sphagnum field under various conditions. Specifically, the present inventors have found that the above object can be attained through provision of a sphagnum cultivation base having a shape-imparted, aggregated mass of dried sphagnum and one or more units of live sphagnum whose stem portions have been aligned in bunch(es), such that the bunch(es) of live sphagnum stem is/are in contact with the aggregated mass of dried sphagnum, that the growth point of of live sphagnum is substantially exposed from the aggregated mass of dried sphagnum, and that the aggregated mass of dried sphagnum is capable of being brought into contact with water of a water basin, and through construction of a system on the basis of the base. The present invention can considerably contribute to environmental improvements, since, in particular, the present invention can grow sphagnum having a remarkable carbon dioxide fixation capacity.

A disk damper is fixed to an end portion of the hub to hold the disk on the hub. The disk damper integrally includes a clamp portion fixed to the end portion of the hub to hold a centre portion of the disk, and a substantially annular straightening portion extending outwards from the clamp portion in a radial direction and facing to a surface of the disk with a predetermined gap.
Abstract:
In an exposure apparatus and an exposure method, a disc master to be used in the preparation of an optical disc is applied to an exposure device, making it possible to perform exposure on a disc master for an optical disc which is substantially improved in recording density. An exposure laser beam by SHG having a wavelength of 300 nm or less is modulated by a modulator, and applied by near field effect to a disc master by using an objective lens having a numerical aperture of 1.0 or more.

Abstract:
A method of magneto-optically modulating light comprises the steps of linearly polarizing the light on its transmission path, placing a magnetooptic effect element on the transmission path of the polarized light with the spontaneous magnetization direction of the element being parallel with the transmission path, the polarized light being modulated into a first light component when the plane of polarization of the polarized light is rotated to assume the first rotational position by the magnetooptic effect element in the absence of the applied magnetic field, applying the magnetic field to the magnetooptic effect element with the internal magnetization of the element being oriented in a direction perpendicular to the transmission path, the polarized light being modulated into a second light component when the plane of polarization of the polarized light is shifted to a second rotational position by the magnetooptic effect element in the presence of the applied magnetic field. According to the method, the light is modulated under the condition that the transmission path is perpendicular to the applied magnetic field, thereby making it possible to direct the transmission path in one of a variety of different directions respectively perpendicular to the direction of the applied magnetic field.
Abstract:
A television receiver converts a television signal of a standard television system currently employed into a signal at a horizontal scanning frequency of n (an integer of 2 or more) times that of the original television signal, so that it can visually reproduce any one of a television signal of the standard television system and a television signal of a second television system, which has a horizontal scanning frequency of about n times that of the television signal of the standard television system. When receiving the television signal of the standard television system, the horizontal deflection circuit operates at a horizontal scanning frequency n times that of the standard television system. When receiving the television signal of the second television system, it operates at the horizontal scanning frequency of the second television system. For the reproduction of the converted signal with the n times horizontal scanning frequency, the interval between the adjacent scanning lines may properly be adjusted by moving them at the horizontal scanning period of the standard television system in the vertical scanning direction.
