Title: Valve switching control method for tappet system for internal combustion engine
Inventor: FUKUO KOICHI
IPC: F01L1/26
Filed: 1986-12-19
Abstract: PURPOSE:To perform valve switching smoothly, by installing a device which connects or releases plural rocker arms, and controlling these rocker arms so as not to operate this connecting means at a time when they are situated in and around a valve opening initial position. CONSTITUTION:Rocker arms 8 and 9, opening or closing plural suction valves and exhaust valves, are installed adjacently to each other. A piston 15, connecting or releasing these rocker arms 8 and 9, is installed in guide holes 15 and 21 of these rocker arms 8 and 9, making hydraulic pressure act on them from a passage 19. When these rocker arms 8 and 9 are situated in a valve opening initial position, a hydraulic circuit is controlled so as not to make the piston operate. With this constitution, connection and release are performed excepting the initial stage of valve opening operation of these rocker arms, so that valve switching is smoothly performable.

IPC: G06T1/00
Filed: 1991-11-19
Abstract: PURPOSE:To provide the information on a three-dimensional face as well as the feature points of a three-dimensional object by sorting shield patterns, and determining the connection point. CONSTITUTION:The corresponding point extraction section C1 of a three-dimensional information extraction section reads the image information from an image input section A, reads the motion information from a motion information input section B, converts them into an epi-polar image, and the correspondence of the feature point is searched and determined. A three-dimensional coordinates extraction section C2 determines the three-dimensional coordinates from the determined corresponding point and the image input section speed obtained by the motion information input section B. A shield pattern determination section D1 determines the shield pattern of the corresponding point on the epi-polar image. A connection point determination section D2 compares the shield pattern and determines the corresponding point to be connected. The accumulation section E1 of a face information generation section E accumulates the obtained connection point information. A three-dimensional face interpolation section E2 generates the three-dimensional face to be interpolated from the accumulated connection point information. The shield patterns are sorted to determine the connection point, thus the information on the three-dimensional face as well as the feature point of a three-dimensional object can be obtained.

Title: Digital information signal recording device
Inventor: SUZUKI TAKAO
IPC: G11B20/12
Filed: 1988-11-30
Abstract: PURPOSE:To improve performance interpolating an error which occurs in a scar in the longitudinal direction of a tape by separately recording an even- numbered sample and an odd-numbered sample, substituting the positions of sectors and setting the continuous recording positions of the samples to have equal distances in the direction of a tape width. CONSTITUTION:The recording area of PCM audio signals are set to be sector constitution, and the even-numbered samples SCA1... and the odd-numbered samples SCA4... are respectively recorded in respective sectors. The sector in which the even-numbered samples SCA1... are recorded and the sector in which the odd-numbered samples SCA4... are recorded can be substituted is SCA1 and SCA4 between recoding areas generated by two continuous scanning. A shuffling processing (rearrangement of array) is performed in such a way that the recording positions of the samples which continue in the time band of a sample sequence have respectively equal distance in the direction of the tape width. Thus, a fear that the samples which continue in terms of time come to error data can be reduced by the scar in the longitudinal direction of the tape.

Title: Sealed lead-acid battery
Inventor: TOKUNAGA AKIO
IPC: H01M10/08
Filed: 1989-11-22
Abstract: PURPOSE:To make addition of only water enough for the initial charge to simplify the production process of a battery by forming secondary or tirtiary particles having a specified particle size by the aggregation of silica fine particles having a specified primary particle size, and impregnating a necessary amount to discharge of sulfuric acid, then filling them in a battery container. CONSTITUTION:Secondary or tirtiary particles having a particle size of 50-200mu are formed by the aggregation of hydrous silica fine powder having a primary particle size of 10-40mmu. A necessary amount to discharge of sulfuric acid is impregnated in these fine particles to form sulfuric acid-impregnated powder 3. Since the powder 3 has fine primary particles and large specific surface area, it keeps a powdery state even if a large amount of electrolyte is impregnated. The powder 3 is filled in a space between a positive plate 1 and a negative plate 2 and in the surrounding of the plates to form a battery. Since the addition of only water is enough for the initial charge, the production process of the battery is simplified. In addition, handling of corrosive sulfuric acid is made unnecessary and productivity is increased.
