Title: Lubricating-oil draining structure for supercharger
Inventor: MIYASHITA TAKESHI
IPC: F01D25/18
Filed: 1979-01-26
Abstract: PURPOSE: To prevent blocking of oil draining ports by lubricating oil itself and to eliminate leakage of oil to blower, by forming a relief groove having a concave cross section on the surface of a seal plate facing a thrust metal in the manner that lubricating oil is by-passed from the inner wall of bearing chamber to oil draining ports.  
     CONSTITUTION: In the surface of a first seal plate 12 facing thrust metal 15, there is formed a relief groove 16 having a concave cross section, which is shaped as a whole in a convex circular form in its front view, disposed eccentrically to the axis of shaft 5, and has a width W 1  equal to or slightly larger than width W 2  of cutout 21 of the first seal plate 12. After completion of lubrication, most part of lubricating oil is passed from the postions of thrust metal 15 and thrust collar 14 to the side face of thrust collar 11 and thrown away in radial direction by the centrifugal force acted thereto. Then, a portion of lubricating oil is dropped by its own gravity and attached to the wall surface of bearing chamber 3, whereas remainder of lubricating oil is passed through relief groove 16 and discharged to the outside from outlet ports 17, 18 without causing blocking of the same.

IPC: H03M7/40
Filed: 1994-01-31
Abstract: PURPOSE:To perform encoding at a high speed, to use a code chart and to provide a high compressibility adapted to data. CONSTITUTION:In this method, the order of the appearing frequencies of characters in input data is divided into the prescribed number of the groups of the appearing probability of 1/a-power-of-two for instance and the input data is encoded by codes consisting of Prefix codes indicating the groups to which the orders belong for the orders of the appearing frequencies and Suffix codes indicating element numbers inside the groups corresponding to the orders. Every time more than one character are inputted, the element number of the group is increased/decreased corresponding to the group of the appearing probability to which the input character belongs. When the input character belongs to the appearing frequency order 1/2<j>, the element number of a probability group (j) is increased/decreased, the element number of the other probability group is increased for the decreased portion and the ratio of the element number to be increased is made proportional to the appearing frequency order probability of the respective probability groups.

Title: Tarbine rotor material
Inventor: KAWAGUCHI KANJI
IPC: C22C38/00
Filed: 1978-01-31
Abstract: PURPOSE: To manufacture a turbine rotor material with superior creep strength at high temp. and superior low temp. toughness by subjecting a steel contg. specific alloying elements to vacuum carbon deoxidation.  
     CONSTITUTION: A molten alloy steel contg. Cr; 10W13%, Mn; 0.3W1.5%, MO; 0.5W1.5%, Si<0.2%, Ni; 0.1W1.0%, Ta; 0.03W1.0%, V; 0.15W0.5%, C; 0.1W 0.3% and N; 0.01W0.1% is subjected to vacuum carbon deoxidation. The deoxidized steed is cast, forged at 1100W1300°C, and heated at 1000W1150°C to form a perfect asstenite structure. It is then quenched to 100°C to convert the structure into a uniform martensite one, and held at around 100°C to be homogenized. Tempering is further carried out at 550W650°C to obtain a tempered martensite structure. Ta(CN) is finely dispersion precipitated in the structure to give superior creep strength at high temp. The vacuum carbon deoxidation reduces the amt. of Si added as a deoxidizer, thus minimizing SiO 2  type inclusions in the alloy and enhancing low temp. toughness.

Abstract: PROBLEM TO BE SOLVED: To shorten the test time by pulling up or down a data bus by the value obtained by inverting the data written on the data bus and then reading the data after writing them in a test object address when the data bus and a memory are tested. SOLUTION: This control system includes a register which stores the data written at a CPU and the circuits 6 to 11 which pulls up or down the data stored in a memory by the value obtained by inverting the data stored in the register. Then a transistor is driven by the output of the register and via a resistance, and a transistor which is inverted in every bit of a data bus is turned on and connected to a power supply or a GND via a resistance. The written data are inverted and the data bus set at the memory is pulled up or down. Thus the failures that are not outputted from the data bus nor the memory can be decided in every bus or bit.

Title: Method for displaying surface of volumetric data without executing interpolation, and graphic system
Inventor: CLINE HARVEY ELLIS
IPC: G06T15/08
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To quickly display the surface of volumetric data and also to display the surface of volumetric data at a speed equivalent to that of a conventional system using the considerably inferior facilities. SOLUTION: A center voxel is selected and tested against the threshold. If the center voxel is lower than the threshold, another voxel is selected as the center one. If the center voxel is higher than the threshold, the diagonal vixels sharing the apex of the center voxel are tested against the threshold. If at least one of diagonal voxels is lower than the threshold, the center voxel is sorted as a surface voxel. The normal vector is decided to the surface of the center voxel based on the value of an adjacent voxel. This process is repeated to many center voxels to decide their surfaces. When an anisotropic voxel 11 is used, the angel of elevation is changed into the effective one. The normal vector decided to the surface of the center voxel is corrected against the anisotropy of data.  Then it's supposed that the voxel has an effective angle of elevation and also has the isotropy that is shown by a controlled surface.

IPC: G10L15/22
Filed: 1994-01-31
Abstract: PURPOSE:To prevent dangerous command execution due to misrecognition of a system by making a user reconfirm whether or not a dangerous command may really be executed. CONSTITUTION:This processor is equipped with a command dictionary 109 wherein whether or not the user reconfirms a command recognized by the system or not is registered, command by command, a reconfirmation decision part 108 which decides whether the user reconfirms the recognized command, and a command execution confirmation part 110. Then it is decided whether or not the user reconfirm the command held by the recognized command holding part 107 by referring to the command dictionary 109. When the user reconfirms the command, the command execution confirmation part 110 makes the user reconfirm whether or not the command recognized by a speech recognition part 106 may be passed to an application program through a speech recognition part 106. Consequently, a dangerous command such as 'file delete' and 'log-out' can be prevented from being executed as a result of misrecognition.
