Title: System and method for automatically correcting registration error in color television camera
Inventor: ROBERT J TOPPER
IPC: H04N9/093
Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To automatically detect and correct a registration error by mutually combining weighted prescribed waveforms and generating an error correction waveform. SOLUTION: An edge detecting part 110 uses one raster relation signal as a reference value and decides the amount and direction of misregistration of each raster relation signal, and a control microprocessor 120 collects and analyzes an error signal that is offered by the part 110, generates a proper weighted value to gain stages 150 and 155 and generates a correction waveform. The stages 150 and 155 apply the weighted value to plural prescribed waveforms 140, an adder 160 adds them and offers an appropriate synthetic correction signal to a pixel shifter/interpolator 170. The interpolator 170 changes the timing of an R signal and a B signal in accordance with the size of a correction signal and generates an R signal and a B signal which are temporally aligned by a G signal.

Title: Speed control method of crane travelling body
Inventor: OUBI NORIO
IPC: B66C13/18
Filed: 1978-01-25
Abstract: PURPOSE: To easily control travelling speed at low speed, by dividing a plurality of induction motors for operating a crane into ones for generating travelling torque and ones for blacking braking, and by each operating said induction motors.  
     CONSTITUTION: The operation of a travelling body is controlled by closing electromagnetic contactors 52R, 52L for positive and reverse revolution and electromagnetic contactors 52PR, 52PL for blacking control. When the positive revolution that needs low speed operation, the contactors 52R, 52PL are closed, and IM-1 and IM-3 are changed into a positive revolution operation mode and IM-2 and IM-4 into a reverse revolution operation mode. If resistances R 1 WR 4  at the secondary side are adequately selected, a work T can suitably be selected to speed V in a resultant torque, and the travelling body is apparently operated in heavy loads even in light loads, thus allowing the control of operation at low speed.

Title: Stationary auxiliary power-supply for vehicle
Inventor: SATO TADAKI
IPC: H02J3/01
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To obtain a stationary auxiliary power-supply which maintains the function of a harmonic-component removal filter as in conventional cases, which makes effective use of energy wasted to the outside and whose efficiency is enhanced by a method wherein a harmonic transformer which is operated by a harmonic-component voltage shared by a harmonic filter is installed and the output of the transformer is utilized for many purposes. SOLUTION: A harmonic-component voltage which is shared across both ends of a filter reactor 2 is input to a harmonic transformer 6. The harmonic transformer 6 is designed in such a way that a voltage at 1.2kHz or higher is output. Consequently, the harmonic transformer 6 outputs a harmonic voltage which is decided by a voltage transformation ratio. The output of the harmonic transformer 6 is utilized as a charging device so as to charge a storage battery. Thereby, a harmonic component which is wasted to the outside as thermal energy can be utilized effectively (as the charging device), and the efficiency of an auxiliary power-supply apparatus is enhanced.

Title: Information retrieving method
Inventor: YAMADA NAOYUKI
IPC: G06F12/00
Filed: 1986-01-17
Abstract: PURPOSE:To retrieve information efficiently by finding a group, which has address information related to the value of a changed object or attribute, from groups stored in a storage device and erasing this group. CONSTITUTION:When one object has only one higher level, hierarchical relations are expressed with a tree structure. That is, indexes are added successively to individual objects in hierarchical relations from the highest level in this case. When one object has plural higher levels, level skip occurs in hierarchical relations. A required number of virtual objects are inserted to the position of level skip in this case to add indexes to objects successively from the highest level. With respect to pointers which are retrieved once and are stored, only pointers to changed objects or objects having changed attributes and attribute values of objects in higher levels cannot be used in relation to changed objects and objects having changed attribute values.

Abstract: PURPOSE: To prevent propagation of bacteria by coating parts brought into contact with water in a water purification device and the insides of branch pipes into which clean water flows with resin containing antibacterial agent. CONSTITUTION: City water flowing into a water purification device 50 from a water supply pipe 54A flows in a filter section 55, and clean water refined by eliminating chlorine and organic matters from the city water therein is supplied to a pipe 4D from a discharge pipe 54B. In order to prevent the propagation of bacteria when chlorine as a sterilizing agent is eliminated, the insides of the discharge pipe 54B of the water purification device 50 and pipe 4D are coated with resin mixed with the antibucterial agent.  When the clean water is stored int he discharge pipe 54B and pipe 4D, the clean water flows backward from the filter section 55 little by little to mix it with the city water in the water purification device 50, and in order to prevent the propagation of bacteria, every part of the water purification device 50 brought into contact with the city water is also coated with resin containing the antibiotic agent. By the constitution, even if the clean water is not used for a long time, the propagation of bacteria contained in the clean water can be prevented.

Abstract: PURPOSE:To secure such a low vibration type engine that is more quiet than a conventional engine,, by setting it down to a fully symmetrical type engine which divides a crankshaft into two shafts,, having respective pistons out of both these crankshafts opposed to each other, and houses them in a cylinder. CONSTITUTION:With pistons 1a and 1b are advanced toward the central part from a bottom dead point at the double end position of a cylinder 3, if they run past suction ports 7a and 7b, an air-fuel mixture is led into each of crank chambers 10a and 10b from a carburetor by way of these suction ports 7a and 7b. Furthermore, if a piston position advances forward, the air-fuel mixture in a combustion chamber 8 is made into high pressure, and when it is reached to a top dead point, it is ignited by spark plugs 11a and 11b, exploded into combustion, thereby pushing these pistons 1a and 1b back. And these pistons 1a and 1b open exhaust ports 5a and 5b, discharging exhaust gas to the outside. Then, the mixture flows into the combustion chamber. Therefore, vibrations to be produced by reciprocating motion of a piston system are negated to each other so that a vibration acting on an engine body is thus abatable.

Title: Pellet bonding device
Inventor: AKIYAMA HIROTERU
IPC: H01L21/52
Filed: 1989-01-13
Abstract: PURPOSE:To remove bubbles in layers of a solder foil and the like and prevent characteristic failure by causing a pellet to earth to a substrate or a lead frame after tilting its pellet and gradually making its angle of inclination small. CONSTITUTION:A collet 1 is allowed to attract a pellet 2 and to place its pellet on an upper part of a frame 3 on which the pellet 2 is mounted in a state that a bonding arm 4 is held in the horizontal position. Once a movable block 7 comes down by the rotation of a motor 11, a supporting shaft 6 comes down and the pellet 2 which is attracted to the collet 1 abuts on the frame 3 where a silver paste and so on are attached in a state that the pellet has an inclination of only an angle theta. If the block 7 comes down, the arm 4 rotates clockwise by taking the supporting shaft 6 as a supporting point and the pellet 2 gradually decreases its inclination. The pellet 2 is thus stuck fast to the frame horizontally while expelling bubbles in the silver paste and then characteristic failure decreases.
