Title: Controller
Inventor: KURIHARA YOUICHI
IPC: G05B23/02
Filed: 1984-03-21
Abstract: PURPOSE:To improve both promptness and safety for operations of a controller by providing a real input correction circuit, by distributing a feedback signal after correcting it into a form where the feedback signal is produced with no time delay when a control signal corresponding to said feedback signal is delivered. CONSTITUTION:The state of a control subject 5 such as a motor, etc. is displayed to a display device 6 via a transmitter 3. An operator operates an operation device 1 while observing the display of the device 6 and drives the subject 5 via a controller 2, the transmitter 3 and a driver 4. In this case, a real input correction circuit 9 receives the input of a feedback signal 8b and a control signal 7a obtained by the device 1 and sent from the controller 2. Then the waveform of the signal 8b is corrected to that of its estimated value and this corrected waveform is displayed to the device 6. Thus it is possible to improve both promptness and safety for operations of a controller having a time delay.

Moreover, the computer receives a car speed data 12A from a counter 12 and outputs a reset command 13B. Then the on-off state of switches 14, 15 is inputted. These inputted data are once stored in the internal memory of the computer 13. The state of the switches 14, 15 is checked here. After that, judgement is made about the condition of exhaust gas absorption, and the data of the distance between cars and car speed data are compared with setting values for judgement. When any car is running just ahead, and its speed is low, the control flag FI is unequivocally set to zero. The result is supplied to an electricity-machine converter 17 as a control command 13D, and a damper 19 is shifted to the intenal air intake direction via a link 17A.

Abstract: PURPOSE:To prevent deterioration of electrical characteristic of a device by stacking two layers of insulation films with different etching rates on an Si substrate, forming an aperture to the upper layer by anisotropic etching, also forming an aperture to the lower layer and thereafter covering the surface with a conductive layer. CONSTITUTION:A P-N-P transistor part and CMOS elements Qp, Qn are formed by the ordinary method on a P<-> Si substrate 1. After covering the surface with SiO2 film 9 and conductive layer 10, the Si3N4 16 and SiO2 17 are stacked thereon. The SiO2 film 9 alleviates a stress on the Si layer 2 by the Si3N4 16. Next, the anisotropic etching is carried out to the SiO2 17 with CHF4, and fine apertures are opened. Thereby, Si3N4 16 prevents damage on the surface of the diffusion layers 12-14 and the SiO2 17 is quickly etched. Moreover Si3N4 16, 9 and deposited contamination are etched with thermal phosphoric acid and an aperture 18 is formed. Next, the conductive layers 19A-19D are provided on the SiO2 film 17 and are connected with the diffusion layers 12-14, and the N<+> emitter 20 is formed by impurity diffusion to the P-type base 13 from the conductive layer 19B. On the occasion of forming an insulation film 21 and an aperture 22, the Si3N4 16 prevents damage and contamination on the surface. A device can be completed with addition of the Al layer 23. Deterioration of electrical characteristic can be suppressed by this structure.
