Title: Oxygen concentration detecting device
Inventor: MIZOGUCHI ASAMICHI
IPC: G01N27/41
Filed: 1993-04-06
Abstract: PURPOSE:To accurately detect the oxygen concentration in an intake gas in a short time by using a limiting current-type oxygen sensor. CONSTITUTION:A microcomputer 60 detects that the current flowing to the sensor main body 20 of an oxygen sensor S becomes to make less changing together with a current detection circuit 50 while the computer 60 impresses a gradually increasing current upon the sensor main body 20 in cooperation with a voltage applying circuit 40. When the detected current stops changing, namely, when the current-voltage characteristic enters a limiting current area, the microcomputer 50 decides the detected current as a limiting current value IP and decides the oxygen concentration (air-fuel ratio) of an intake gas based on the value IP. The oxygen concentration can be accurately detected in a short time, since the limiting current value does not change even when the current-voltage characteristic of the limiting current-type oxygen sensor S changes in accordance with the temperature, but changes in accordance with the oxygen concentration.

Title: Preventing method for corrosion of heat exchanger for heating aqueous salt solution
Inventor: WATANABE SABUROU
IPC: C01D3/04
Filed: 1981-05-27
Abstract: PURPOSE: To improve the corrosion resistance of a heat exchanger and to enable the use of an inexpensive SS material as a material of the exchanger by charging an aqueous NaCl soln. into an electrolytic cell after adding a reducing agent and by heating the soln. through the heat exchanger.  
     CONSTITUTION: In a heating method for an aqueous NaCl soln. charged into an electrolytic cell through a heat exchanger, to the soln. to be heated is added a reducing agent beforehand. The preferably used reducing agent includes Na 2 SO 3 . By adding a very small amount of CoCl 2 .6H 2 O as a reduction accelerator together with Na 2 SO 3  as the reducing agent, the corrosion of the exchanger is preventd almost thoroughly. The reason why the corrosion is inhibited by adding the reducing agent is estimated to be that a trace of O 2  dissolved in the soln. takes part in the corrosion and the dissolved O 2  is removed by adding the reducing agent or further adding the reduction accelerator.

Abstract: PURPOSE:To make uniform the temperature distribution between crystal substrates and also between each crystal substrate and the next as well as to grow a high quality crystal in an excellent mass-productive manner by a method wherein a high frequency coil to be used for heating is provided on both sides of a doughnut-shaped susceptor. CONSTITUTION:The first high frequency coil 27 for heating and the second high frequency coil 28 for heating are provided on both sides of a doughnut-shaped susceptor 22 on which a plurality of crystal substrates 23 can be placed. The substrate 23 are heated up by the high frequency current which is induced by the action of the magnetic field formed by the coil 27. The current flowing to the circumferential part of the outer substrates 23 is larger than the current flowing to the inner circumferential part, the temperature of the outer circumferential part is higher than that of the inner circumferential part. The substrates 23 is heated up by the high frequency current induced by the action of the magnetic field formed by a coil 28. As the current flowing to the inner circumferential part of the substrate 23 is larger than the current flowing to the outer circumferential part, the temperature of the inside part is higher than the temperature of the outer circumference. The temperature distribution between the substrates 23 and the temperature distribution on the substrate 23 are made uniform on the whole. As a result, high quality crystal can be grown in an excellent mass- productive manner.

Title: Method and apparatus for representation of feature of fingerprint
Inventor: ARASUTEA SHIBARUDO
IPC: G06V10/42
Filed: 1991-03-22
Abstract: PURPOSE: To make it unnecessary to analyze a fingerprint itself by an automatic correlation technique for comparison by comparing recorded data with data indicating at least another automatic correlation pattern, deciding the same fingerprint, and displaying the characteristic of the fingerprint. CONSTITUTION: An automatic correlation pattern is generated when two same pictures are superimposed. The correlation pattern depends not only on the feature of an original picture, but also on a coefficient, vector declination between common reference points on each picture, and relative angle displacement (orientation) between two pictures. When two pictures are mutually displaced so that a displacement distance can be half an interval between the ridges of a 'fingerprint' pattern, the 'dark' line of a second picture traveling in parallel to the direction of the displacement is not affected, and the 'dark' line of the second picture traveling in a direction orthogonally crossing the displacement direction arrives on a space between the 'bright' lines on a first picture so that the new 'dark' area, that is, an interference 'domain' can be formed.
