IPC: G01G11/00
Filed: 1994-05-17
Abstract: PURPOSE:To provide a weighing device which can automatically adjust the timing for starting the processing of weighing signals when a conveyor in which a taking conveyor and a weighing conveyor are made to overlap each other is used. CONSTITUTION:A computing means 30 computes the time required for an article M to pass the overlap portion R between a weighing conveyor 12 and a taking conveyor 14, according to such parameters as conveyor velocity V, the length L of the article, and the length A of the overlap, and so the timing for starting the processing of weighing signals can be adjusted automatically through the detection of the article M by a sensor 8. A weighing signal processing circuit 38 starts processing of the weighing signals from the adjusted timing and can obtain data on the weight of the article M which show measured values.

IPC: G06T7/00
Filed: 1990-05-19
Abstract: PURPOSE:To improve fingerprint collation rate by excluding the small part of low quality such as a bridge generated due to sweat in a fingerprint ridgeline part in a fingerprint picture from the selected object of dictionary data when a fingerprint dictionary is generated. CONSTITUTION:A fingerprint input part 1 receives the ridgeline part of a fingerprint by a CCD element 45 through a glass plate 43 and a lens 44, and outputs analog data. A picture input part 2 is provided with a binarization circuit and a binary memory, and binarizes and stores the analog data of the fingerprint in the memory. Then, a collation circuit part 3 is provided with a collation circuit and a dictionary memory, and stores the fingerprint registered before in the dictionary memory, and the collation circuit compares and collates inputted binary data and the contents of the dictionary memory with each other. At that time, the fingerprint picture detected by a fingerprint sensor is divided into plural small areas, and when the small area containing a feature point and brighter than a prescribed threshold is detected in the fingerprint picture, the picture data of the bright small area is excluded from the generation of the fingerprint dictionary. Thus, the collation rate can be improved.

Title: Water lifting type cylindrical network filter
Inventor: TANAKA KAZUMA
IPC: B01D47/00
Filed: 1981-08-18
Abstract: PURPOSE:To purify air by immersing the bottom end of a filter produced by contg. plural sheets of circular nets spacially in a perforated cylinder into water and rotating the filter thereby producing water foam films covering the meshes continuously and capturing the fine dust contained in the air forcibly. CONSTITUTION:An annular filter which is produced by adhering circular nets 3 to both surfaces of cap rings 1 provided with bucketlike cuts 2 on the inner side and contains a water lifting bucket on the inner side is contained at suitable intervals in a cylinder 4 made of a perforated plate. Rotating shafts 5 are mounted to both ends of the cylinder 4 and the stanchions supporting the shafts 5 are formed into a screw shape so that water feeding force is generated when the filter is rotated. The laminated cylindrical filter obtained in such a way is kept immersed in the semicircular part in the water tank of an air purifier and is rotated in said state, whereby air is sucked. The water foam films produced when the nets 3 submerge in water contain the fine dust in the air and form water drops which are adsorbed by the water overflowing from the buckets, and are further washed when the filter is immersed in water by rotation.

Abstract: PURPOSE:To decrease unbalance voltage and to obtain the Hall element having good sensitivity by rounding the four inside corner parts existing on the outside circumference of a pattern part having a cruciform shape. CONSTITUTION:The four inside corner parts 3 existing on the outside circumference of the pattern part 2 having the cruciform shape of the photomask for printing the pattern of the Hall element having the cruciform shape on a photoresist are rounded 12.
