  • Publication number: 20240132566
    Abstract: Disclosed is a method for producing a fusion protein of human serum albumin and human growth hormone. The method comprises (a) a step of culturing a mammalian cell capable of producing the protein in a serum-free medium and causing the protein to be secreted into the culture fluid, (b) a step of collecting a culture supernatant by removing the mammalian cell from the culture fluid, and (c) a step of purifying the protein from the culture supernatant by using column chromatography using a material to which an antibody having an affinity for the protein is bound as a stationary phase, column chromatography using a material having an affinity for phosphate group as a stationary phase, cation exchange column chromatography, and size exclusion column chromatography.

  • Patent number: 11938346
    Abstract: A particle beam therapy apparatus has a position and posture setter that moves a movable body, that is at least one of the irradiation nozzle and the treatment table. A movement path of the movable body is determined when adapting the positional posture of the movable body from one condition among a plurality of prescribed conditions to another condition. An evaluation value is obtained for adapting the positional posture of the movable body to each of a plurality of prescribed conditions. This evaluation value is for a case of moving the movable body according to the movement path. A setting order is determined for adapting the positional posture of the movable body to each prescribed condition based on the evaluation value; and the positional posture of the movable body is adapted to each of the plurality of prescribed conditions by moving the movable body according to the determined movement path.

  • Patent number: 11342211
    Abstract: The present disclosure provides a wafer inspection technology that involves less degradation of the image quality even when an object to be observed has a variation in height due to warpage, etc. of a wafer. This wafer inspection apparatus obtains an image with less degradation by: adjusting the focal point of an observation optical system to a height measured by a height sensor for measuring wafer surface heights; and further, correcting a switching signal for a CCD line sensor on the basis of stage position data and optical magnification data corresponding to the height so as to make a correction corresponding to the wafer surface height.

  • Publication number: 20040043219
    Abstract: Upon wet etching and thereby patterning carbon nanotubes (106) by a transfer method, a solution for dissolving a binder used in the transfer method as a solution used for the wet etching is used, and the carbon nanotubes (106) tangled with each other are rubbed off with a cloth-like substance (112) upon the wet etching. Furthermore, upon patterning the carbon nanotubes (106) using a dry etching method, a metal film or a film made of a substance resistant to damage upon the dry etching and causing no damage to the carbon nanotubes (106) when removed is used as a mask. A fine carbon nanotube pattern having an excellent flatness is formed.

  • Publication number: 20040036401
    Abstract: To provide a method for manufacturing a high-performance field electron emission apparatus, wherein occurrence of damage to a CNT during a manufacturing step is prevented, and thereby, the CNT can adequately keep an inherent electron emission characteristic of exhibiting a large current density with a low threshold value. This method for manufacturing a field electron emission apparatus is related to the manufacture of a field electron emission apparatus using the CNT as an electron source. In the method, a protective film formation step is performed in order to form an aluminum film 4 as the protective film on the surface of the CNT film 2 during a manufacturing process of at least a part of the apparatus. The CNT surface structure is protected with this conductive protective film (aluminum film 4, 40), while the structure significantly affects the electron emission characteristic. Consequently, the electron emission characteristic inherent in the CNT can be adequately ensured and be exhibited.

  • Patent number: 5119189
    Abstract: A stereoscopic imaging system enabling observation of a stereoscopic image due to parallax by reproducing, on a single screen in an image-reproducing means two kinds of images of an object which are taken by two imaging units and between which there is parallax and by observing the images in such a manner that the left and right eyes of the observer observe only the separate images taken by the separate imaging units corresponding to the left and right eyes, wherein there is provided swing means for mechanically or electronically shifting the optical axes of the respective lenses of said two imaging units, by which swing means the observer can view a stereoscopic image without fatigue and in a natural condition.
