Title: Condenser
Inventor: HIRASAWA SHIGEKI
IPC: F28B1/06
Filed: 1981-10-29
Abstract: PURPOSE:To improve condensing performance without increasing any pressure drops in heat transfer tubes by changing the intervals of the partition plates in headers to decrease the number of heat transfer tubes per pass of flow passages for a heat medium gradually from a steam inlet thereby making the flow speed of the steam per pass constant. CONSTITUTION:Headers 1 which distribute heat medium steam into the inside of heat transfer tubes 2 are provided on both end sides of the many heat transfer tubes 2, and partition plates 3 for constituting flow passages for the heat medium in plural passes are provided in the headers 1. The numbers N1, N2... of the heat transfer tubes per pass are changed by setting the intervals of the plates 3 suitably by setting the intervals of the plates 3 suitably. Therefore the flow speed of the steam in the heat transfer tubes other than the final pass is made constant and the performance of condensation is improved without increasing the pressure drops in the tubes.

Title: High speed pattern recognition manhattan distance calculation process using thermometer coding
Inventor: L RODNEY GAUK
IPC: G06K9/62
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To provide high speed pattern recognition process high in the processing efficiency of a hardware. SOLUTION: Pattern collation requires the calculation of 'distance function' for measuring the level of a difference between two patterns. This calculation uses 'sum of absolute value of difference' or the function of 'Manhattan distance'. When a high speed Manhattan distance function is executed for a vector having a short component, an input feature vector and a known vector are transformed into thermometer coding form (404). Next, by XORing two thermometer code vectors, the difference of these vectors is calculated (406). Next, by counting the number of bits of a value '1' in the result of XOR, the Manhattan distance is calculated. By storing two thermometer code vectors in bit slice form, the utilization of parallel calculation is possible.  By storing a binary code feature vector in bit slice form, a required memory capacitance is reduced and the transformation from the binary code to the thermometer code can be utilized.
