IPC: G06T7/00
Filed: 1989-08-04
Abstract: PURPOSE:To set proper retrieval conditions without reference to the size of a graphic form and to perform efficient graphic form recognition by setting the conditions for retrieving other segments according to the length of a segment which is extracted firstly. CONSTITUTION:For the retrieval 3 of the start point segment of symbol detection 4, the kind of an extracted segment and the range of segment length are set. Here, the segment kind is set to a vertical segment (v) and the segment length Ls is set to a value based upon segment length information. Namely, when the length of a read vertical segment is within the range of the set segment length Ls, the segment is stored in a segment register as the start point segment. In retrieval right after the start point segment is detected, it is conditioned that the start point of a segment to be retrieved is within a retrieval area of size corresponding to the length of the start point segment and the length of the segment to be retrieved is within a range corresponding to the length of the start point segment, and control 5 is performed so as to retrieve other segments.

Filed: 1992-07-30
Abstract: PURPOSE:To increase the efficiency of a result factor by a method wherein a refrigerant from a compressor is caused to flow to a liquid receiver through a condensing part as it is condensed, a refrigerant is caused to flow from the liquid receiver through a sub-cool part to be cooled in a sub-cool state, and a fixed throttle part is arranged in a refrigerant passage running from the condensing part to the liquid receiver. CONSTITUTION:A heat-exchanger 12 is partitioned into two regions by means of partition plates 26 and 29. A region to which a high temperature gas refrigerant flows through an inflow port 24 from a compressor forms a condensing part 13, and a region to which a liquid refrigerant flows through an inflow port 28 to the liquid receiver 15 forms a sub-cool part 16. A fixed throttle part 14 is arranged in a refrigerant passage 31 running from the condensing part 13 to the liquid receiver 15. Since a sub-cool region 40 the area ratio of which is changed according to a refrigerant flow rate is formed at the region on the downstream side of the condensing part 13, a result factor COP can be most efficiently increased by the fixed throttle part 14 regardless of the magnitude of a refrigerant flow rate. Further, a freezing cycle is reduced to a compact state and can be mounted in a limited place.

Abstract: PURPOSE:To prepare concentrated argon, by the independent pressure-swing operations using zeolite molecular sieve and carbon molecular sieve filled in separate adsorption devices. CONSTITUTION:Air is passed through the first adsorption device filled with zeolite molecular sieve, and subjected to the pressure-swing operation (PSA operation) to obtain a gas composed of e.g. 94% of O2, 1% of N2 and about 5% of Ar. The obtained gas is used as the raw material, and subjected to the short- time PSA operation using the second stage adsorption device filled with carbon molecular sieve to adsorb O2 and increase the Ar concentration to about 40%. O2 gas having a purity of about 97% can be obtained as the desorbed gas by this process, and accordingly, the process is useful for the concentration of O2 in the raw material gas. The obtained gas rich in Ar is further subjected to the PSA operation using the third stage adsorption device filled with carbon molecular sieve to adsorb and remove the remaining O2 and concentrate Ar to a concentration of 85%.
