Abstract: PURPOSE:To improve cooling capacity of an accelerating electrode for lowering temperature rise so as to suppress thermal distortion and an out gas amount to a small extent by arranging a cooling dome in a ring-shaped space part inside an accelerating electrode so as to form a circulating passage of a fluid on the outer peripheral side and the inner peripheral side of the cooling dome. CONSTITUTION:A cooling dome 11 is mounted inside a ring-shaped space part 3a of an accelerating electrode 3 for being connected to a supply tube 9 and a discharge tube 10, while passages 12a of plural stripes of spiral grooves are processed on the outer periphery of the cooling dome 11. Further, the passages 12b are formed on the inner peripheral side of the cooling dome 11 and the passages 12c are formed on the tip part. The fluid having constant temperature supplied from the supply tube 9 enters the outer periphery of the cooling dome 11 and spirally flows through the spiral groove passages 12a processed on the outer periphery. By forming the passages like these almost allover the accelerating electrode 3 can be uniformly cooled without stagnation of the fluid, while improving cooling capacity due to an increased heat transfer rate so as to reduce temperature rise.

IPC: A61K38/00
Filed: 1985-03-30
Abstract: PURPOSE:To provide an antitumor agent containing ganglioside GM3 as an active component and useful for the remedy of leukemia. CONSTITUTION:The objective agent contains ganglioside GM3 as an active component. Ganglioside GM3 is a kind of sphingoglycolipid existing as a minor constituent component of cell membrane. It has been found recently that highly characteristic increase of ganglioside GM3 takes place by the differentiation of monocytic macrophage cell and that ganglioside GM3 is effective to induce and promote the differentiation of said cell. The activity of ganglioside GM3 to induce the differentiation of the transformed cell and to develop the activity of functional cell is supposed to be effective to induce the cancerized cell to decancerized cell thereby developing the original functions of the cell and curing leukemia. A significant life-prolonging effect was clearly found in an experimental leukemia mouse.

Title: Printed matter inspector
Inventor: KIMURA HIROAKI
IPC: G01N21/892
Filed: 1991-04-01
Abstract: PURPOSE:To achieve a higher capacity of detecting defects of a printed matter by a method wherein scanning is performed separately using two filters and two systems of line sensors corresponding thereto and outputs thereof are added being weighted to make sensitivities of color inks equal with relative ease. CONSTITUTION:Multi-color printed matter running is lighted and the resulting reflected light is received and converted into an electrical signal with a line sensor. An inspection of the printed matter is performed based on the electrical signal. Line sensors 1a and 1b employ adhesion line sensors using a crystal semiconductor. A white light source uses a 3-wavelength type fluorescent lamp to perform a high frequency lighting. Adhesion line sensor filters 2a and 2b use interference film filters; the filter 2b is a blue color filter and the filter 2a a red color filter. Output signals of the line sensors 1a and 1b are added up with an inversion addition circuit. The weight of the two outputs varies depending on a ratio of a resistance R1 to that R2 and thus, sensitivity ratios of inks are kept almost constant by adjusting the resistance thereby enabling judgment of defects.

Title: Metallic film formation
Inventor: ANDO YASUNORI
IPC: H01L21/3205
Filed: 1987-03-23
Abstract: PURPOSE:To prevent increase of contact resistance at the boundary by conducting, in addition to deposition of a metal to a base material, a first ion irradiation using an ion of hydrogen and inactive element and a second ion irradiation using at least a kind of ion among silicon, group IIIb and group Vb elements and then conducting again the first ion irradiation. CONSTITUTION:A base material 6 is loaded, for example, to a holder to be housed in a vacuum vessel. A vaporization source 12 and an ion source 20 are arranged toward the base material 6. With deposition of a metal to the base material 6, irradiation of a first ion consisting of at least a kind of ion of hydrogen and inactive element and irradiation of a second ion consisting of at least a kind of ion of silicon, group IIIb elements and group Vb elements are conducted and thereafter the first ion irradiation is conducted again. Irradiation of ion in addition to deposition of metal allows formation of a metal film having good crystal property on the surface of base material and also prevents increase of contact resistance at the boundary of metal film and base material due to irradiation of ion. Moreover, increase of specific resistance of metal film is little detected.

Title: Thin film transistor
Inventor: HOSOKAWA YOSHIKAZU
IPC: H01L27/12
Filed: 1985-04-02
Abstract: PURPOSE:To make it possible to obtain low-ON-resistance even if high OFF resistance is provided, by constituting a polycrystalline silicon thin film by two layers of a high resistance layer and a low resistance layer, and forming a channel in the low resistance layer. CONSTITUTION:A high resistance polycrystalline silicon layer 12 and a low resistance polycrystalline silicon layer 13 are laminated on an insulating substrate 11, and a polycrystalline silicon region is formed. The thickness of the high resistance layer is formed, e.g., within a range of 0.1-1.0mum. The thickness of the low resistance layer 13 is formed, e.g., within a range of 0.01-0.3mum. Since the substrate 11 is contacted with the high resistance layer 12, a parasitic channel is not formed even if electric charge is accumulated at an interface with the substrate. Therefore, a current is not increased at the OFF state. Thus, the device, whose ON resistance is low and OFF resistance is high, can be obtained. A device, in which P-type or N-type impurities are doped in the low resistance polycrystalline silicon layer 13 and the resistance is made further lower, can be used. Thus, the film thickness can be made thin, without decreasing the electric field mobility of the polycrystalline silicon layers, which form the channel region.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To easily change the size of an active window by calculating a zoom- out size and performing display on a display device in response to focus transition from a first window to a second window. SOLUTION: A display screen 200 can display an optional number of windows, and the window 210 is provided with a focus in a default state. Thus, a graphical user interface(GUI) places the window 210 in the highest layer of the other windows. Besides, the GUI delivers the focus to the window 210, and in the case that the window 220 or 230 is present, simultaneously 'zooms out' the window. Thus, for the windows 210, 220 and 230, respective zoom-out buttons 212, 222 and 232 are switched between the default state and a zoom-out state. At the time, the windows 220 and 230 keep displaying original contents, however, the dimensions of the height and width are automatically reduced by a prescribed calculation.
