Title: Blow-by gas discharging device for engine
Inventor: ABE KENJI
IPC: F01M13/00
Filed: 1994-07-14
Abstract: PURPOSE:To suppress the increase of a cost to a minimum and maintain the overall height of an engine to a low value on the cassion of prevention of oil in a valve system chamber from flowing to an air cleaner. CONSTITUTION:An air chamber 40 is formed in a head cover by the chain damper 23 of a head cover 5 serving as a partition. The air chamber 40 is communicated with a chain chamber 17c through an air flow port 41 and communicated with an air cleaner. Since the chain damper 23 is also functioned as the lower wall of the air chamber 40, there is no need to add a new part so as to prevent inflow of oil to an intake system. This constitution reduces the increase of a cost and eliminates a need for variation of the structure of the head cover 5, whereby the overall height of an engine is not increased.

IPC: E02B3/00
Filed: 1992-05-28
Abstract: PURPOSE:To make the inner district of a harbor where the mouth of a river is formed a calm area, and enable turbid water including sediment which flows out of the river to the inside of the harbor to be discharged out of the inside of the harbor to the outside of the harbor. CONSTITUTION:Each turbid water passage caisson 10 is arranged in a sea district 40 opposite to the river mouth 42a of a river 42. A first opening 22 is formed in an inner surface 12 faced to the inside 44 of a harbor partitioned by the caissons 10, and a second opening 24 is formed in an outer surface 14 faced to the outside 46 of the harbor, so that a turbid water passage hole 20 connecting both the openings to each other is provided. The first opening 22 is formed at a place higher than the second opening 24, turbid water flowing in the harbor 14 is discharged out outside the harbor through the turbid water passage hole 20 as water level in the vicinity of the outer surface 14 fluctuates due to the movement of waves outside the harbor 46. The passage effect of turbid water is accelerated by letting waves reflected downward by a wave reflecting surface 18 flow in the turbid water passage hole 20 through a wave inflow port 30.

Abstract: PURPOSE:To minimize the deterioration in the electric characteristic due to a dielectric plate by adopting a double structure for a dielectric cap so as to adjust the interval of the dielectric material plates. CONSTITUTION:A double structure comprising 1st and 2nd dielectric plates 2a, 2b is adopted for a cap part covering the tip opening of a horn of a dielectric resin cap 2.

Abstract: PURPOSE:To decrease the splashing of excess mists by providing an object which has a surface wider than the surface of materials to be coated and moves cyclically on the rear surface of the materials to be coated and sticking the oversprayed mists onto this object. CONSTITUTION:Liquid or the like is sprayed SP1 from a spray nozzle 1 and the atomized particles are stuck and applied on the surfaces of the materials O1, O1a,... to be coated. Since the size of the spray coating patterns is larger than the individual surfaces of the objects O1, O1a,... to be coated, the oversprayed particles passes the spacings S between the objects which are continuously fed and passes along both sides of these materials O1, O1a,... as well and arrive at the surface of a conveyor belt 7 traveling below the same, thus sticking thereto. The mists sticking onto the conveyor belt 7 gather to form a liquid layer Pl. The liquid is turned back and is scraped Pl1 by a scraper 8 or the like, by which the liquid is accumulated PL in a liquid collecting layer 9 below (Pl1), from which the liquid is returned to a tank and is reutilized.

Title: Recognition system for linear pattern
Inventor: HARADA HIROAKI
IPC: G06V10/44
Filed: 1981-10-13
Abstract: PURPOSE:To recognize the shape of a block diagram even in case of a compound gate circuit by allowing a sensor to move only on segments constituting a rectangular figure. CONSTITUTION:For the recognition of a compound gate circuit shown in the figure, when a sensor reaches an intersection P1 on a connecting line, connection information on the terminal point P1 of the segment is written in a connection information memory. Then, an advance from the intersection P1 is made as shown by an arrow. At an intersection P2, the sensor start moving straight. Then, the sensor advances on block lines even at intersections P3-P7 similarly to return to the starting point P1. Thus, segments of the block diagram as a symbol are scanned to obtain a sequence of feature points of the block diagram. On the basis of this feature point sequence, the symbol is specified. For symbol extraction, a feature-point extracting circuit starts to read feature point coordinates out of the connection information memory and unprocessed picture elements out of an origin picture memory, generating a sequence of different points. This feature information is written temporarily in a shape information memory and then a matching circuit starts processing.

Data of the channel which generates the correct result can be used as it is. Even if two channels don't generate correct results by themselves, data of each channel is analyzed, and correct parts of their data are combined to generate one correct decoded result.
