Title: Reconstruction system for data base
Inventor: NAKAJIMA KOICHI
IPC: G06F12/00
Filed: 1990-11-22
Abstract: PURPOSE:To attain the reconstruction of a data base by recognizing the type of a chain based on the corresponding chain type number contained in the chain control information which is included in a data record. CONSTITUTION:A chain definition maintenance means 11 is started with an instruction and registers a chain definition part in a directory 12. Then a chain production means 15 is also started with an instruction and produces a chain related to the corresponding chain type into a prescribed date record stored in a data base 1 by reference to the chain definition and by means of a work file 18. A chain deletion means 16 deletes the chain out of the base 17 by referring to the directory 12. A work program 13 performs the prescribed processing in parallel with definition and the cancel of the chain type. A date operation means 14 is started by a program 13 and performs the operation of the date record stored in the base 17. In regard of the chains to be processed by the means 11, 15 and 16, the means 14 performs each processing with monitoring so as to evade the reconnection of chains. In such a constitution, the base 17 reconstructed with no saving operation.

Title: Video image recording and reproducing device
Inventor: MORISHIMA NORIHIRO
IPC: H04N11/04
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To obtain the small sized and inexpensive video image recording and reproducing device by utilizing an arithmetic unit used for image coding without addition of a PLL circuit so as to reduce the circuit scale. SOLUTION: An input video signal is converted into a digital signal at an A/D converter 10 by using a clock signal which is the quadruple of the frequency of a color burst signal from a clock signal generator 40 and received by a frame memory 20. An MPU 30 conducts modulation/demodulation of a luminance signal and color difference signals of an image of the received video signal and compression/expansion of the image and records the compressed image code to a recording area 50. Since phase information required for color separation is obtained from a color burst signal, no PLL circuit is required for color demodulation and data with the luminance and chrominance signals superimposed on them are received, the capacity of a frame memory is saved, the circuit scale is reduced and the small sized and inexpensive video image recording and reproducing device is obtained.

Title: Processing method for cylinder of engine
Inventor: FUJII TAKASHI
IPC: B65B33/02
Filed: 1987-12-17
Abstract: PURPOSE:To grind a cylinder wall of an engine sufficiently, by making a ratio between stroke displacement speed and rotational direction displacement speed of a grindstone small at around the deepest position at the combustion chamber side at the time of coarse finish, and making the ratio uniform at the time of finish. CONSTITUTION:At the time of honing coarse finish, the stroke displacement in the axial direction of a cylinder 11 is temporarily stopped at the lowest end position for the stroke displacement of a grindstone 5; and if rotation alone is conducted during that period, the grinding amount for the lower part of a cylinder wall 11A, which is adjacent to a curved surface 11B, is increased; therefore, insufficient grinding does not happen; the precision of cylindrical degree for the cylinder wall 11A, even for holes which are not bored through, is improved. However, on the lower part of the cylinder wall, a pattern in which grooves in parallel emphatically runs is given; under this condition, forming of oil film becomes uneven. Because of thin, for the finishing stage, the ratio between stroke displacement speed and rotational direction displacement speed of the grindstone is made uniform; if the grindstone is made to stroke continuously while rotating, on the whole surface of the cylinder wall 11A, a uniform crosshatch pattern is completed.

Title: Parabolic antenna device
Inventor: MAKINO TETSUO
IPC: H01Q15/24
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To finely adjust the polarization plane of radio wave. SOLUTION: A polarizing plane adjusting means 30 is provided for rotating a radiator 25 provided at a parabolic antenna 10A around its radiation axis (z). The polarizing plane adjusting means 30 performs the fine adjustment to the polarization plane of radiator. While any adjacent channel interference or the like occurs, the radiator 25 is rotated around the (z) axis and the polarizing plane is inclined. When the polarization plane is inclined, even when any interference wave enters, its received electric field strength is reduced in comparison with a desired wave so that the influence of interference wave upon the desired wave can be reduced and since the received electric field strength is improved by adjusting the deviation of polarized waves on the transmission side, the quality of received radio waves can be improved in any case.
