Abstract: PURPOSE:To reduce pressure loss and to aim at miniaturizing an exhaust purifying converter, by arranging catalyst layers which are spaced in the direction orthogonal to an exhaust gas passage and in multi-stages within the converter, and by connecting adjacent upper and lower catalyst layers, alternately at both inlet and outlet sides of the converter. CONSTITUTION:In a catalyst converter composed of a gas inlet cone 11, a converter casing 12 and a gas outlet cone, the inside of the converter casing 12 is divided into right and left spaces by means of a partition wall 21, and catalyst casings 14 are arranged in the substantially horizontal direction in five stages at equal intervals in both left and side spaces. Gas permeable screens formed of wedge wire screens or the like are arranged on both surfaces of each catalyst casing 14. Further, the inside of each catalyst casing 14 is divided by a gas partition plate 15 between the converter casing 12 and the catalyst casing 14 and a gas partition plate 14 which connects the catalyst casings between the inlet side and outlet side thereof, alternately, and therefore, the gas inlet side 17 and the gas outlet side 20 of each catalyst layer are completely separated from each other, thereby it is possible to produce both gas down-flow stream 18 and gas upper-flow stream 19.

Title: Bioelement
Inventor: SAITO MINORU
IPC: G01N27/416
Filed: 1990-02-22
Abstract: PURPOSE:To dispense with an external pressure in the self-oscillation of an artificial film by a method wherein the pH of the salt solution on a low- concentration side among salt solutions, between which the excitative artificial film, which has adsorbed a fatty material having an oleyl group is interposed, is set at a specified value or lower. CONSTITUTION:An artificial film 11 is supported in a state that it is in contact to both of 100mMKCl of an aqueous solution 15a housed in an electrolytic cell 13a and 5mMKCl of an aqueous solution 15b housed in an electrolytic cell 13b. HCl is added to the aqueous solution 15b in this cell 13b and the self- oscillation of a potential in the case where the pH of the aqueous solution 15b is changed is measured. Whereupon, as the pH is decreased, an oscillation starting pressure is steeply reduced and when the pH reaches a pH4, the pressure becomes unnecessary. Moreover, when the pH is reduced, a DC current is also reduced gradually and becomes unnecessary in a pH2.5 or lower. In the pH2.5 or lower, the oscillation is generated without applying the external pressure and the DC current and this oscillation frequency is increased as the pH is reduced and is changed into a distorted waveform in a pH1 or lower.

Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To accurately detect malfunction caused by turbulence from a transmission line route by providing a detecting means for a pulse with a crest value out of a prescribed range of a terminal fitting. SOLUTION: A pulse row formed by outputting pulses by a pulse generating portion 4-1 in a defined crest value and width range by number proportional to watt-hour is fed to a terminal fitting 3 connected with a transmission line route via a pulse transmitting portion 4-2. A pulse row at the terminal fitting 3 that is most easily affected from the transmission line route is sent to a pulse detector 5-1. The pulse detector 5-1 detects existence of error pulse with a crest value and a width out of the defined range. Therefore, it can be detected that turbulence from the transmission line route causes the pulse error to occur at the terminal fitting 3. In addition, by transmitting the detection result to a receiving device, the receiving device can detect that count of pulses has error.
