Patent EP-0430269-A2 (EP)
Inventor: KATOH KENJI
IPC: B01D53/94
Filed: 1990-11-29
Abstract: An exhaust gas purification system for an internal combustion engine using an alcohol blended gasoline fuel includes a lean NOx catalyst (2) capable of reducing nitrogen oxides under an oxidizing gas condition and in the presence of hydrocarbons. A bypass conduit (3) is provided with a bypass valve (4) so as to bypass the lean NOx catalyst (2). Opening of the bypass valve (4) to cause the exhaust gas to flow through the bypass conduit (3) is controlled in accordance with the alcohol concentration of the fuel. When the alcohol concentration (C AL ) is low, the bypass valve opening range is limited to a high engine speed and high engine load range, so that the exhaust gas is caused to flow through the lean NOx catalyst (2) at low and medium engine speeds and low and medium engine loads, and the catalyst (2) is utilized at a maximum. On the other hand, when the alcohol concentration (C AL ) is high, the bypass valve opening range is determined so as to include a medium to high engine speed and medium to high engine load range, so that the exhaust gas is caused to flow through the bypass conduit (3) at medium engine speeds and medium engine loads, and useless degradation of the lean NOx catalyst (2) is prevented.

Abstract: A digital-to-analog converter device includes a digital filter (6) for producing a digital signal (Vd) which is applied to an attenuator (16). The attenuator (16) attenuates the digital signal by a level (L DTH ) corresponding to the level of a dither signal (Vg, Vℓ) to be added to the digital signal, and produces an attenuated digital output signal (Vh) having an attenuated level (L ATT ). The dither signal (Vg, Vℓ), which is generated by a dither generator (14, 17), is added to the attenuated digital signal (Vh) by an adder (11). A sum signal (Vi) from the adder (11) is converted by a D/A converter (12) into an analog signal (Vj), from which the dither signal (Vg, Vℓ) is removed by a low-pass filter (8).

Abstract: A gene from  Clostridium thermohydrosulphuricum  DSM 3783 encoding a thermostable alpha-amylase-pullulanase enzyme was cloned encoding in  Escherichia coli  as a 7 kb insert using a lambda-vector. For subcloning pUC18 and pUC19 plasmids were used. Using a  C. thermohydrosulphuricum  promoter at least ten different sizes of soluble intracellular thermostable, mostly degenerated polypeptides having both alpha-amylase and pullulanase activities and M r  in the range 165 000 to 100 000 were produced. The temperature optimum of these polypeptides was (80-85°C), some 5°C lower than the temperature optimum of the extracellular enzyme from the native host, but the heat stability was the same as that of the native enzyme. The enzymes can be used alone or in combination with a glucogenic or a maltogenic enzyme for effective hydrolysis of starch and pullulan.

Abstract: An integrated circuit input buffer is adapted to operate at either of two input levels, typically either TTL or CMOS logic levels. This is accomplished by switching an additional transistor (e.g. 15) into a path between the output node (e.g. 12) and a power supply voltage (e.g. V DD ), thereby changing the ratio of the pull-up to pull-­down devices (e.g. 14, 13). The desired input level may be selected after the manufacture of the device, as by applying a voltage to a package terminal, or by programming a register during operation of the integrated circuit.

Abstract: A method of producing a hose having low permeability comprises the steps of preparing a rubber mandrel (2) having an outer releasing layer made of fluoride rubber, applying a silicon-based releasing agent having a viscosity of 300 - 1000 cs to the releasing layer in a state where the mandrel (2) is being moved, and extruding a molten resin and coating it onto the releasing agent-applied mandrel (2) while the mandrel (2) is being moved, thereby forming a resin layer (7). By virtue of the provision of the releasing layer and also the application of the releasing agent to the releasing layer, the releasability of the mandrel (2) is enhanced, thereby preventing the resin layer of the resultant hose from being injured when the mandrel (2) removed therefrom. Hence, if the hose is used for transferring a refrigerant gas such as Freon, it is free from gas leakage, and shows high durability.

Abstract: The bar-code reading apparatus and method identify a block of a main-part bar code by detecting the start (SB) and end (EB) guard bars, determine the right end (RGB) of the main-part bar code based upon whether all the characters in the block carry even parity, detect an add-on bar code a predetermined interval after the right end, and read the add-on bar code thus detected. The apparatus and method also determine whether a plurality of sets of add-on characters are read which differ in the number of characters, as a result of different scans of the bar code (scan B, scan C). The sets of add-on characters are compared character-by-character for equality in character code and in parity, up to the final character of the smallest set, and, on a match, the set having the largest number of characters is selected as being the correct add-on bar code. As a result, add-on bar codes can be detected reliably and efficiently.
