Title: Control device for engine
Inventor: AIGA SHOICHI
IPC: F02D45/00
Filed: 1990-09-21
Abstract: PURPOSE:To prevent impossibility of learning owing to production of a fluctuation in engine rotation by prohibiting variation of the magnitude of an external load by means of a load varying means when the degree of updating of learning is low, based on an output from a degree of updating detecting means to detect the degree of updating of learning of a learning control means. CONSTITUTION:A CPU 40 is provided with a learning control means to control learning of an air-fuel ratio, a degree of updating detecting means to detect the degree of updating of learning by a learning control means, and a prohibiting means to prohibit variation of the generating voltage of an external load (an alternator 13) by a load prohibiting means (a regulator 19) when the degree of updating of learning is low, based on an output from the degree of updating detecting means. The degree of updating of learning of the learning control means for an air-fuel ratio is detected, and when the degree of updating of learning is low, variation of the intensity of the generating voltage of the alternator 13 by means of the regulator 19 is prohibited, based on an output from the degree of updating detecting means. As a result, the fluctuation in rotation of an engine 16 owing to variation of the generating voltage of the alternator 13 during learning where the degree of updating of learning is low can be prevented from production and stable control of learning can be carried out.

Filed: 1998-09-08
Abstract: PROBLEM TO BE SOLVED: To enable the data transfer in a DMA(direct memory access) system which efficiently performs data transfer and also does not monopolize a bus even without providing an additional circuit or considering a DMA transfer cycle with a program. SOLUTION: An interval register 9 stores a DMA operation authorized period and a DMA operation enabling signal is made ON/OFF in each of the period. While a DMA transfer request signal in an ON state is supplied from a CPU 10, a DMA unit controlling part 6 checks the state of the DMA operation enabling signal, requests the CPU 10 for the right of using a system bus 14 when it is in an ON state, makes plural blocks transfer data between a memory 11 and input-output devices 12 and 13. On the other hand, when the DMA transfer enabling signal is made OFF, the DMA unit controlling part 6 interrupts data transfer with a DMA transfer interrupt signal and also releases the right of using the system bus 14 to the CPU 10.

Filed: 1985-11-14
Abstract: PURPOSE:To increase the frequency of a probe and to reduce its size and to improve microdefect detection performance by fitting a screen type electrode on one surface of flat plate type piezoelectric ceramics and sticking a sound absorber on the opposite surface. CONSTITUTION:The screen type electrode 14 which is applied with a pulse voltage 13 from an ultrasonic flaw detector 21 is fitted on one surface of the flat plate type piezoelectric ceramic 12 and the sound absorber 15 which absorbs a generated ultrasonic wave is stuck on the opposite surface. Then, the end edges of the piezoelectric ceramic 12 and sound absorber 15 on a surface-wave advance side are cut into a slanting plane 17 so as to propagate a surface wave 11 to an object body 8 efficiently. Further, a surface wave 18 sent to the opposite side from the surface wave 11 about the screen type electrode 14 impedes flaw detection, so corner parts of the piezoelectric ceramics 12 are rounded into a curved surface 19, so that the surface wave advance around to the reverse surface without being reflected and is absorbed by the sound absorber 15 on the reverse surface. Consequently, the surface wave 11 is propagated efficiently on the surface of the object body 8 to detect a microdefect on or nearby the surface accurately.

Title: Waveform shaping circuit
Inventor: KATO TERUO
IPC: H03K5/08
Filed: 1993-10-13
Abstract: PURPOSE:To suppress the production of an output signal due to noise when no input signal is received by providing a hysteresis characteristic on the waveform shaping circuit. CONSTITUTION:An input signal amplified by a differential amplifier 2 is amplified by a 1st stage amplifier circuit including a transistor(TR) 6 and further amplified by a 2nd stage amplifier circuit 15 including TRs 16, 17. An output of the differential amplifier turns on/off a TR 6 depending on a collector current of TRs 7, 8 flowing through current mirror circuits 3, 4, 5. Then a feedback circuit 18 comprising the current mirror circuit comprising TRs 19-23 and a current mirror circuit comprising a constant current source 24 and TRs 25-27 is used to apply a control signal corresponding to the output level to the input of the TR 6. Positive feedback is applied to the base of the TRs of the amplifier stage to provide an offset to the circuit thereby producing a hysteresis characteristic, and then the amplifier stage is not operated even with application of noise when no input signal is received and erroneous output is prevented.
