摘要： A data processing system including a central processing unit (CPU), a memory device operating on a data word length of 2 m-bits, an input/output device operating on a data word length of m bits, an m-bit register and a direct memory access (DMA) controller for transferring data words in both directions between the memory device and the input/output device independently of the CPU. A 2 m-bit bus is connected between the memory device and two m-bit buses connected to a bus switching circuit which controls the transfer of m-bit data words between the 2 m-bit bus and the register and the input/output device. A control circuit generates timing and switching signals such that, during a first bus cycle a first m-bit data word from the input/ouput device is stored in the register, and during a second bus cycle a second m-bit data word from the input/output device is transferred directly via the buses to the memory device and, also, the first m-bit data word, stored in the register, is transferred to the memory device. For transfer of a data word from the memory device to the input/output device, during a first bus cycle m bits of data are transferred directly via the buses to the input/output device and, also, the following m bits are stored in the register, and during a second bus cycle the following m bits are transferred to the input/output device.

摘要： A liquid-condition detection element is provided which exhibits good sensitivity while having appropriate strength. The detector element forms part of a liquid-condition detection sensor in which breakage of the detection element is combated and which can accurately detect the condition of liquid. The detection element includes first and second ceramic insulating layers formed by simultaneous firing and a heat-generating resistor sealed in a liquid tight manner between the insulating layers. The resistor has a resistance varying with temperature, and is, in use, immersed in liquid. The first insulating layer is thinner than the second layer. A detection section of the liquid-condition detection sensor detects the condition of a liquid (e.g., the concentration of a particular component in the liquid) on the basis of an output signal from the heat-generating resistor.

摘要： The present invention provides a method and apparatus using a gas concentration sensor for accurately controlling an air fuel ratio in an internal combustion engine, featuring in that before the fuel-vaporized gas purged from the canister enters into the intake manifold whereat the sensor detects the gas concentration of the purged gas, the sensor is adjusted so as to adjust a zero point (or zero output level) of the sensor output. In step 100 of FIG. 7, a judgment is made as to whether the flow rate of air reaches a predetermined level. In step 110, processing for zero-point correction of the gas concentration sensor is performed. Specifically, in a state in which the purge valve 17 is closed, concentration of purge gas is measured by use of the gas concentration sensor 4, and a sensor output S1 at that time is obtained. Subsequently, the sensor output S1 is compared with a correct sensor output S0 in order to obtain a difference &Dgr;S therebetween. Accordingly, during subsequent gas concentration measurement, a value S3 obtained through subtraction of the difference &Dgr;S from an obtained sensor output S2 is used as a correct sensor output. In step 120, a supply amount of purge gas, i.e., a concentration of the purge gas to be supplied is obtained. In subsequent step 130, the purge valve 17 is driven in order to supply purge gas to the intake pipe 2 in a required amount (A%).

摘要： A gas concentration sensor comprises an ultrasonic element 33 opposite a reflection surface 34. A depression 34a is formed on an edge portion of a reflection surface 34 which is in contact with a side wall of a measurement chamber 32 such that a bottom surface of the depression 34a is substantially in parallel with the reflection surface 34. The distance between the ultrasonic element 33 and the edge portion of the reflection surface 34 becomes greater than the distance between the ultrasonic element 33 and a central portion of the reflection surface 34. As a result, an indirect wave, which impinges obliquely on the side wall of the measurement chamber 32 and propagates along the side wall, is reflected from the bottom surface of the depression 34a and propagates. Thus, the propagation distance of this indirect wave becomes greater as compared to the case where the reflection surface 34 is flat, so that the indirect wave is not combined with a direct wave in the vicinity of a modulation point of the direct wave. That is, since the modulation point of the direct wave can be detected accurately, a time interval between a modulation point of a transmitted wave and that of a received wave can be measured as the propagation time of an ultrasonic wave, thereby enabling accurate determination of gas concentration.

There are provided an adder for summing the length of decoded portions in the variable word length instruction in accordance with the progress of the instruction decoding, and another adder for adding the length of the decoded instruction portions to the program counter so as to update the program counter. Further, there is provided a circuit for calculating an operand effective address by using the value of the program counter in the course of the variable word length instruction decoding. Thus, the updating of the program counter and the generation of the effective address are concurrently executed.
