Title: Control system for thermal power plant
Inventor: ONO KEIMEI
IPC: G05B13/04
Filed: 1986-08-27
Abstract: PURPOSE:To obtain the best review timing for a control gain by deciding visually deterioration in the performance of a controller due to characteristic variation of a process. CONSTITUTION:The difference between a state predicted value calculated by a process model 3 and the state quantity of a process 1 is computed by a subtracting mechanism 5, whose subtraction result value is smoothed exponentially by a data processing block 6 so as to eliminate variance in value and then compared with a positive and a negative preset guide line value; if the value exceeds the positive or negative guideline value, the absolute value of excessive data is integrated. Thus, excessive data on all state quantities are integrated and then the respective integral values are multiplied by weight values set for the respective state quantities and all summed up, so that the sum is compared with a predetermined criterion. If the value exceeds the criterion, it is decided that the difference in characteristics between processes 1 and 3 is large, and it is indicated on a CRT 7 that the state quantities are improper for the control over the process 1.

Filed: 1989-08-04
Abstract: PURPOSE:To display only the detection signal image in which the closed crack by excitation is in a prescribed open state and to allow the execution of the checking of the presence, size, position, etc., of the flaws by detecting the phase of the oscillation that an exciter excites an object to be tested and applying modulation of luminance, color, etc., to the detection signal image in sychronization with this phase. CONSTITUTION:The body 1 which is to be tested and is excited by the exciter 5 is opened and closed in the closed crack of a flaw 2 according to the oscillation thereof. Since the propagation characteristics of ultrasonic waves fluctuate according to the open state of the flaw 2, the reflection of the ultrasonic waves transmitted from a probe 3 changes as well. The reflected waves in the flaw 2 detected by the probe 3 are sent to a display device 6 where the waves are displayed as the detection signal image. A luminance modulating circuit 7 detects the phase of the oscillation generated by the exciter 5 and controls the modulating function of the display device 6 in synchronization with the phase thereof. The detection signal image is modulated in luminance in this way and only the detection signal image corresponding to the open state meeting the phase is brightly displayed. The other detection signal images are not displayed.

Particularly, the chitosan is harmless to the human body.  In addition, the calcium-chitosan composite has the extremely high bond as compared with the chitosan composite with other metals and even more this composite has the property of the extremely high power to adsorb amino acid materials (including bacteria) and therefore, the composite is the antimicrobial agent most adequate for the apparatus for medical goods and food.

Abstract: PURPOSE:To provide an ultrasonic touch panel where touch position is specified by providing an ultrasonic transmission/reception means on the surface of a non-piezoelectric substrate and sensing the touch of a finger, a material, or a spot of laser light to this surface. CONSTITUTION:When a linear chirp signal having a frequency band DELTAf1-1 or DELTAf1-2 is inputted from an interdigital electrode for input, the electric signal having the frequency which is changed in accordance with the electrode period length of the interdigital electrode for input is converted to a surface acoustic wave and is propagated in a non-piezzoelectric substrate 1, and the surface acoustic wave whose wavelength is approximately equal to the electrode period length of an interdigital electrode for output is converted to a delay electric signal, and this signal is outputted.
