Title: Working method for valve seat in cylinder head
Inventor: SUZUKI MASAHISA
IPC: B23K26/34
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To prolong the life of a cutting tool by minimizing the cutting margin of a highly hard boundary layer formed at a boundary between a cylinder head base material and a dissimilar metal layer. SOLUTION: A recessed groove 14 is formed on the opening edge side of the port 2 of a cylinder head 1. A dissimilar metal layer 20 is filling-formed on the recessed groove 14. Cutting work is applied to the dissimilar metal layer 20 to form a tapered guide surface 4 on the interior part side, a valve seat surface 5, and guide surfaces 15, 25 on the opening side, forming a valve seat. The guide surface 15 on the opening side is previously formed before filling- forming the dissimilar metal layer 20. The dissimilar metal layer 20 is then cut to flush with the guide surface 15 on the opening side. This minimizes the cutting margin t1 of a boundary 21 having unavoidable simultaneous cutting.

Title: Vehicle tracking syste using global positioning system (gps)
Inventor: ARISON KEI BURAUN
IPC: H04W64/00
Filed: 1992-05-06
Abstract: PURPOSE: To obtain a tracking system using a GPS satellite which can obtain a position, a speed and time information of a moving body such as vehicles or the like correctly. CONSTITUTION: The tracking system comprises a sensor 20 set to each object to be tracked, a communications link 30, a work station 40 and a GPS reference receiver 60. Position accuracy of the sensor is updated at any time by the work station via the communications link 30. The sensor continuously measures through a visible GPS satellite a pseudo area and a delta area, or a time difference, and a frequency error. Unprocessed measured values from the satellite are, together with a related timing and state information, supplied to the communications link 30 and returned to the work station 40 cyclically. The error is corrected at the work station, so that determination accuracy for a position of the object is improved. Although measurements at three points by the satellite are required in general to calculate the position of the object, measurements at least at two points will do in a short period if time, altitude and map-assisting information are fed to the work station.

Title: Compact disk reproducing device
Inventor: KONO EIICHI
IPC: G11B27/10
Filed: 1989-06-05
Abstract: PURPOSE:To contrive the efficient scheduling by distributing the difference of a musical performance time and the total musical performance time to intermusic. CONSTITUTION:When the head melody NO is inputted by ten keys and a SET key 14 is depressed, a control part 9 displays the head melody NO on a display 7. When the final melody NO is inputted by the keys 15 and the key 14 is depressed, the final melody NO is displayed. When the key 14 is further depressed, the control part 9 executes an access to a CD driving part 2, reads out the musical performance time extending from the head melody to the final melody, calculates the total time Tl and displays the melody NO to be performed and T1 on the displays 6, 7. Subsequently, a desired musical performance time T2 is inputted by the keys 15, displayed on the display 6 by depressing the key 14, a space time SP1 inserted into intermusic is calculated by dividing the time obtained by subtracting T1 from the time T2 by a value obtained by subtracting ''1'' from the number of melodies to be performed, and the device becomes a READY state. Next, by a PLAY key 12, the control part 9 repeats a musical performance of the head melody, insertion of SP1, a musical performance of the next melody, and insertion of SP1, and the musical performance of N melodies is ended during the time T2. In such a way, the efficient musical performance scheduling can be performed.

Abstract: PURPOSE:To prevent the sag of ink from an ink jet head at all times by mounting a check valve between the head and a two-way valve. CONSTITUTION:A check valve 10 is inserted between a two-way valve 9 and a head 1. A two-way valve 6 is ON-OFF controlled by a control signal (a) from a sequence circuit, and the two-way valve 9 is turned ON temporarily.

Abstract: PROBLEM TO BE SOLVED: To automatically detect the video part in which an erroneous image is inserted by reducing the image of an image changed point as a feature scene, displaying a still image, further, arranging the time information of the image changed point and displaying the time information. SOLUTION: An moving image reproducing device fetches an outputted frame image fn (304). Next, whether a cut point exists between the fn and the frame just before the fn or not is decided (306). If the cut point exists, the present time is substituted for Tcur, a difference is taken between the time and the time Tlast of the cut changed point just before, and cut time length Tdur is determined (310). Then, on the two-dimensional array I 1 for storing an icon image which is defined as a representative screen, the contents of the same array I 2 is copied (312). Subsequently, the frame image fn is reduced as necessary and the image is copied on the array I 2 (314). When the determined Tdur is smaller than a set threshold Th 1, the icon image stored in the I 1 is displayed on a display (318).

Abstract: PURPOSE:To obtain a perpendicular magnetic anisotropic film having high S/N even at <=100 deg.C substrate temp. by forming a magnetic layer consisting of Co, Cr, Ni, P and trace impurities on a substrate. CONSTITUTION:The magnetic layer consisting of Co, Cr, Ni, P and trace impurities is formed on the substrate. A thin film type magnetic recording medium for vertical recording having the high S/N even in a short wavelength region is thereby obtd. even if a substrate such as polyethylene terephthalate film having poor heat resistance is obtd. The perpendicular magnetic anisotropy is not enough and the vertical recording is not possible if the amt. of the Cr to be added is below 7wt%. The output in the short wavelength region obtainable in such a case is extremely low. Ms is too small and the output is extremely low if the amt. of the Cr to be added exceeds 26wt%. The amt. of the Cr to be added is, therefore, required to be maintained within a 7-26wt% range.
