Title: Propellant tank for space plane
Inventor: MORI TAKASHIGE
IPC: B64G1/14
Filed: 1991-04-10
Abstract: PURPOSE:To reduce the movement of the center of gravity as a tank so as to stabilize flight and to control the center of gravity of an airframe by partitioning the interior of a propellant tank into plural chambers in the longitudinal direction by light-tight partition walls, and making the propellant in each chambers move relatively between required chambers. CONSTITUTION:Even if a space plane take an elevation angle, for example, and a tank 1 is inclined, with the tail lowered, a propellant is kept from totally moving to one end of the tank 1 by a partition wall 2 to stay in the first, second and third chambers, keeping the liquid levels 5 as shown in the drawing. Accordingly, as the whole tank, the center of gravity little moves so as to continue normal flight. All of the transfer pumps 4 provided on the lower ends of the respective partition walls 2 are operated in the direction of a propellant's moving to the first chamber or the third chamber, whereby the center of gravity of the tank 1 can be moved to the right or the left. By utilizing the above principle, the center of gravity of the space plane can be always kept in a required range regardless of the attitude.

Abstract: PURPOSE:To regenerate and adsorbent for carbon dioxide for removing carbon dioxide from aspiration gas and realize the continuous use of the adsorbent in the title system mounted onto an aeroplane in which aspiration gas from which carbon dioxide is removed is allowed to circulate into a gas feeding passage. CONSTITUTION:The gas for aspiration which is bleeded from the compressor of an engine is supplied into the mask M of a driver through a gas feeding passage L1 by the supplement of the oxygen supplied from an oxygen cylinder 3 in a mixing chamber 2, and the aspiration gas discharged into the mask M is returned into the mixing chamber 2 through a gas circulation passage L2. In this case, the gas circulation passage L2 is branched into two branched passages L2a and L2b through a pair of rotary selector valve 8 and 9 which are interlocked with each other, and carbon dioxide gas removing devices 10a and 10b are installed and the both devices 10a and 10b can be regenerated alternately. The regeneration is carried out by introducing the high temperature air into heating tanks 13a or 13b through a selector valve 25 and by discharging the carbon dioxide adsorbed onto an adsorbent 12.

Title: Circuit for driving display device, display method, mechanically readable recording medium and display system
Inventor: LIN TSUNG-NAN
IPC: G09G3/36
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To make gradation plottable in a display device by generating uniform dot patterns by using a distributed dot screening technique to a distributed dither matrix. SOLUTION: The output of a multiple threshold processor 58 is a quantized dither matrix value Dij Q to be inputted to an active level comparator 60. Moreover, active levels of a linear quantization table 62 are also inputted to the comparator 62. The comparator 62 decides whether the dither matrix value corresponding to a current pixel is in an active level or an inactive level by comparing respective active levels with the current quantized dither matrix value Dij Q. A pixel output generator 56 receives a dither pixel value Pdith from a comparator 54 and receives a level active value Latv from the comparator 60. Then, when the current pixel value exceeds a corresponding dither matrix threshold value and the quantized dither matrix value is one of active values of the quantization table of a current frame, the generator 56 generates Pout =1.

Title: Grooved drill
Inventor: OKADA YOSHIYASU
IPC: B23B51/02
Filed: 1986-04-05
Abstract: PURPOSE:To shorten a time required for grinding of a blade and to reduce the occurrence of seizure of a cutting edge, by a method wherein a V-shape groove is formed in a spiral manner along the two roots of a drill. CONSTITUTION:The thickness of the center of a cutting edge is divided into three equal parts, and a V-shaped 60 deg. groove with a depth being one third the thickness thereof is formed in a spiral manner along the two roots of a drill. Since an outer blade breaks after a blade of groove breaks and a drill serves as a 2-stage type, vibration of a core can be prevented from occurring. Since a work of removing the thickness wall of a central part is eliminated, a grinding time can be decreased, seizure of a cutting edge is difficult to occur, and sharpness of a blade is improved.

Abstract: PURPOSE:To detect the center position of a through hole accurately in a non- destructive and non-contact manner, by scanning the detection surface of a proximity switch which generates the oscillation amplitude varying according to the eddy current loss as detection output on a multi-layer printed circuit board. CONSTITUTION:A proximity switch 7 is so arranged that the oscillation amplitude at an oscillator section 7a changes due to an overcurrent loss as a metal material approaches a leakage magnetic field generated in an oscillation coil 7b and the output level varies according to the changes in the amplitude. A decision section 8 discriminates the coordinate point of the position where the output level of the proximity switch 7 decreases depending on the presence of a through hole while determining the center position based on the results of the discrimination. Then, the surface of a printed circuit board 4 is scanned with the proximity switch 7 to detect the position of the through hole with the decision section 8.
