The present invention provides an exhaust gas purifying catalyst that is capable of substantially reducing the degree of deterioration in an exhaust gas purifying capability, which results from dissipation of an absorbent agent. Accordingly, an exhaust gas purifying catalyst, which includes a carrier and a catalyst layer, and to which at least one material selected from a group of alkali metals and alkali earth metals is added as an absorbent agent, is characterized in that acid material with a high affinity with respect to the absorbent agent is mixed in the catalyst layer so as to fix the absorbent agent, and an inhibiting layer is formed between the catalyst layer and the carrier so as to inhibit the movement of the absorbent agent toward the carrier.

摘要:
In an exhaust gas purifying catalyst, an acid material with a high affinity with respect to an absorbing agent is dispersed and mixed in a catalyst layer, to which the absorbing agent is added, or a layer of the acid material is formed inside the catalyst layer in order to prevent the absorbing agent from moving from the catalyst layer into the carrier. This reduces the permeation of the absorbing agent added to the catalyst layer into a carrier, the evaporation and splash of the absorbing agent from the catalyst, and the deterioration in the durability and the exhaust gas purifying performance of the catalyst.

A screw member having a loosening prevention function is provided to improve a fastening power and a relative strength in thread connection. With an arrangement to provide a first crest portion and a second crest portion at the opposite ends of a thread point, a first screw member generates a loosening prevention effect due to elastic deformation of the first crest portion and the second crest portion, with the entire thread flank from the base portion to the point brought into contact with a second screw member on the both surfaces of the thread flanks. With this arrangement, a strong fastening power can be obtained, and a clamping force applied to the thread is distributed over the thread, thereby enabling improvement in the relative strength in thread connection.

A precharge circuit and a bit line load circuit are provided to a read bit line pair. The bit line load circuit continuously supplies a prescribed current to a read bit line. When data is written to one of memory cells selected in common by one read word line, the level of each read bit line will not be lowered to the level of the ground potential by the bit line load circuit if a read word line is activated, and therefore the loads of both discharge and charge operations by transistors in the memory cell are reduced.

A cache memory with a data memory divided into a plurality of word arrays, each of which is selectable by a word select indicator. Each word array is further divided into a plurality of bit arrays, each of which correspond to a bit of a word, and include congruence set memories for each congruence set. A bit array is connected to a sense amplifier via a congruence set selector, thereby one set of congruence set memories of the word arrays in the data memory is selected, and one congruence set memory is selected from each of the bit arrays by a congruence set selector to be connected with a sense amplifier, so that only one sense amplifier has to be provided for each bit in each word in an entry of the data memory, thus eliminating the need to increase the number sense amplifiers as the number of congruence sets increases. Furthermore, as only the sense amplifier associated with the selected word array is operational, current consumption is reduced.

A pipeline data processor includes an instruction fetch unit, an instruction decoding unit, an address calculation unit, an operand fetch unit and an instruction operation execution unit. After an instruction, or a part of an instruction, is sent from the instruction fetch unit to the decoding unit, the decoding unit decodes at least a portion of the instruction. For some instructions, the decoding unit outputs two or more step codes to achieve processing of a single operand address. In one embodiment, the operand specifier of the instruction includes a base value and at least one address extension field. The decoding unit outputs a first step code based on the base value and, subsequently, a second step code based on the address extension field. In another embodiment, an operand specifier can include up to an arbitrary number of address extension fields. The decoding unit outputs a step code corresponding to the base value of the address and another step code for each of the plurality of address extension fields. The address calculation unit sequentially receives the plurality of step codes which relate to a single operand and, when address calculation of the operand is completed, sends the result as a fuuther step code to the operand fetch unit.

A data processor of the present invention adopts a multi-stage indirect (chained) addressing mode, and merges pipeline processing units which are generated with respect to each designation of the chained addressing mode into a pipeline processing unit expressing the operation information for the operand of the instruction after completion of address calculation, thereby processing loads at each stage are equalized and processing speed as a whole apparatus increases.

A vibratory transducer comprising a vibratory beam composed of an n-type layer and having at least one end fixed. The vibratory beam is formed by selectively etching an n-type layer formed by adding impurities locally to a single silicon crystal. The vibratory transducer also comprises means for vibrating the vibratory beam and means for detecting vibration of the vibratory beam. The vibratory transducer measures pressure, temperature, density, etc, by detecting change in the resonant frequency of the vibratory beam. The vibratory beam can be finely etched irrespective of the density of the impurities therein by forming the vibratory beam in an alkaline aqueous solution while applying a negative DC or pulsed voltage to a p-type layer and a positive DC or pulsed voltage to an n-type layer. The vibrating and detecting means for the vibratory beam can be easily provided by making a diode and a transistor including the vibratory beam in the transducer.

An insole the material for which is made from a elastomer showing gum-like elasticity under the normal temperature, and which is provided with a wedge-shaped profile, irregularities, curves, and the like for the purpose of making the sole incline or correcting the state of unevenness thereof. It is used by being inserted inside shoes, slippers, sandals, etc., or by being worn on the sole of the foot with the aid of socks, simple holders or band bodies being molded integrally with the holders. Further, it may be made by utilizing a foam-formed body, or by boring small holes for air permeation therein for retaining warmth or making it light-weight.
