  • Publication number: 20220275779
    Abstract: An object of the present invention is to provide a working method of an orifice, which has excellent working accuracy and high productivity in order to work an inclination portion (tapered portion) on the entire circumference of an inner wall of an orifice. Therefore, a working method of an orifice includes a first step of forming an orifice hole 54d in an orifice forming member, a second step of pressing a downstream end surface of the orifice forming member in which the orifice hole 54d opens, in a direction toward an upstream side of the orifice hole 54d by a punch 46 having a cutting blade portion 46a larger than a cross section of the orifice hole 54d. The second step causes a material of the orifice forming member to flow from an entire circumference at the downstream end portion of the orifice hole 54d to an inside of the orifice hole 54d to form a cross-sectional area reduction portion 54s in which a cross-sectional area of the orifice hole 54d is reduced from an upstream side to a downstream side.

  • Publication number: 20130003022
    Abstract: A polarizing prism is shaped in the form of a hexahedron. A polarizing beam splitter film (PBS film) is arranged approximately in a diagonal direction of the hexahedron. The polarizing prism holds a relationship of A<B when the dimension thereof in an outgoing direction (Y direction) of a light beam to a screen is A and the dimension thereof in an incident direction (X direction) of a light beam from a light source is B. For example, the polarizing prism is shaped in the form of a rectangular parallelepiped. At a plane on which the light beam is launched from a scanning mirror, one end of the PBS film is placed so as to intersect with the incident plane at an angle of approximately 45° at a position deviated inside by a difference between the dimensions A and B from the end of the incident plane.

A block unit movement vector searching unit (4) detects a block unit movement vector (BMV) by carrying out block matching processing. A movement vector correcting unit (5) carries out miniblock division processing to generate a movement vector (BV) if a movement correction error is equal to or greater than a threshold value. A pixel unit movement vector generating unit (6) generates a movement vector with a smallest error component between a frame signal of a current frame and a frame signal of an immediately preceding frame as a movement vector of a pixel.

  • Patent number: 5249037
    Abstract: In a motion-adaptive television signal processor, a field as a reference for a moving picture signal includes a signal delayed by a frame memory or a field memory. A non-standard signal is beforehand processed so as to separate Y and C signals, and the signal thus processed is input to a motion-adaptive processor to thereby reduce a deviation in center of gravity between a still picture signal and a moving picture signal on the timebase to thereby suppress unnatural motion of the picture.
