摘要:
A reflective color liquid crystal display device with a liquid crystal layer sandwiched between a first substrate having a light reflectibility and a second substrate having a light transmissibility. The liquid crystal layer being composed of twist-aligned nematic liquid crystal having a positive dielectric anisotropy. A circularly polarizing unit, including a single linear polarizer plate, selectively passes either right handed or left handed circularly polarized light out of natural light. The circularly polarizing unit is disposed so that a major surface of the circularly polarizing unit is on a liquid crystal layer side, the circularly polarized light exiting the circularly polarizing unit through the major surface when natural light enters the circularly polarizing unit. Various parameters of the liquid crystal layer are optimized for a liquid crystal layer having a twist angle in the range of 0° to 100°.

A high pressure rubber hose has a plurality of reinforced layers. Each reinforced layer is buried by way of an intermediate rubber layer between an inner rubber layer and an outer rubber layer, in which an organic fiber reinforced layer braided from organic fiber cords into two spiral layers or one braided layer is disposed to the inner rubber layer on the outer circumference thereof. A steel wire reinforced layer braided from steel wires into two spiral layers is disposed to the organic fiber reinforced layer at the outer circumference thereof. The braiding angle of the organic fiber reinforced layer is less than braiding angle of the steel wire reinforced layer and the braiding tension of the organic fiber reinforced layer is higher than the braiding tension of the steel wire reinforced layer.

An impact-resistant display apparatus is constituted by a display panel, a drive circuit for driving the display panel, a face plate disposed in front of the display panel, and a support member for supporting the display panel and the drive circuit. The display apparatus further includes a first elastic member between a rear side of the display panel and the support member, and a second elastic member between a front side of the display panel and the face plate. The first and second elastic members may preferably respectively define and almost closed space together with adjacent associate members so as to provide an air damper-effect.

A scheme for detecting shot boundaries in the compressed video data at high speed and high accuracy. In this shot boundary detection scheme, a Predictive-picture (P picture) change is calculated from a P picture sequence in the input video data which is compressed by an inter-frame/inter-field forward direction prediction coding scheme, according to coded data contained in the P picture sequence, while an Intra-picture (I picture) change is calculated from an I picture sequence in the input video data which is compressed by an intra-frame/intra-field coding scheme, according to coded data contained in the I picture sequence. Then, a shot boundary is detected by evaluating both the P picture change and the I picture change.

A modified polyolefin resin obtained by reacting a polyolefin resin with an epoxy group-containing acrylamide monomer represented by the following general formula I:H.sub.2 C.dbd.CR--CO--NH--CH.sub.2 --Ar:wherein Ar represents an aromatic hydrocarbon group having 6 to 24 carbon atoms which is substituted with at least one glycidyloxy group and R represents a hydrogen atom or a methyl group) in the presence of a free-radical initiator is herein provided.A thermoplastic resin composition comprising 5 to 95% by weight of the foregoing modified polyolefin resin and 95 to 5% by weight of another thermoplastic resin is herein provided.Further, a filler-reinforced polyolefin resin composition comprising 100 parts by weight of the foregoing modified polyolefin resin and 3 to 300 parts by weight of an inorganic or organic filler is herein provided.
摘要:
Disclosed is a method of detecting the position of a symmetrical article by converting image signals of the article into binary information and detecting the position of the article based on the binary information. A first median point is determined, from the binary information, that is between two points of intersection between a first straight line intersecting the article and the sides of the article. A second median point is determined, from the binary information, that is between two points of intersection between a second straight line passing through the first median point, crossing the first straight line at right angles and crossing the sides of the article. Sequentially, 3rd to (n-1)th median points are similarly determined from the binary information, and finally, an n'th median point is determined from the binary information, that is between two points of intersection between an n'th straight line passing through the preceding (n-1)th median point, crossing the preceding (n-1)th straight line at right angles and the sides of the article. The position of the symmetrical article is detected by using the n'th median point as the central point of the article.
摘要:
In a MIS random access memory device including a data-in amplifier and MIS memory cells, a device is provided for holding the output level of the data-in amplifier at the precharge potential of the memory cells except during a write operation by controlling an input circuit and a driver circuit of the data-in amplifier through utilizing the read/write signal and the control signal for the memory. Data stored in the memory cells are free from the influence of the output of the data-in amplifier during a non-write operation.

A method for producing a group 13 nitride single crystal includes dissolving and crystal growing. The dissolving includes dissolving nitrogen in a mixed melt in a reaction vessel that contains the mixed melt, a seed crystal, and a surrounding member. The mixed melt contains an alkali metal and a group 13 metal. The seed crystal is a seed crystal that is placed in the mixed melt and includes a group 13 nitride crystal in which a principal face is a c-plane. The surrounding member is arranged so as to surround the entire area of a side face of the seed crystal. The crystal growing includes growing a group 13 nitride crystal on the seed crystal.

A gallium nitride crystal having a hexagonal crystal structure includes a first region located on an inner side of a cross section intersecting c-axis of the hexagonal crystal structure, and a second region surrounding at least a part of the outer periphery of the first region in the cross section. An emission spectrum of each of the first region and the second region with electron beam or ultraviolet light excitation has a first peak including a band edge emission of gallium nitride and a second peak located in a longer wavelength area than the first peak. A peak intensity of the first peak is smaller than a peak intensity of the second peak in the first region, and a peak intensity of the first peak is greater than a peak intensity of the second peak in the second region.
