The ultimate goal of an industrial robot is to make full use of its real ability to communicate with any given intelligent device, and to do so independently of hardware, architecture and languages. This paper describes the necessary functions of a robot used in an integrated manufacturing system, and the basic philosophy of organization as applied to the robot controller. An example of a machine vision system called MYVIS is reviewed in relation to MAP and LAN in a practical cell application.

This paper shows that using the multivariable controller reduces the magnitude of fluctuations of the control signals which result improved control of the steam generator outputs. Comparison of the performance of the multivariable weighted adaptive controller(MWAC) with the performance of the existing PI controller and the self_tuning controller/1/, when the system goes through a transient mode, shows that the out-puts stay closer to their set points when they are controlled by the adaptive controller.

In this paper an FIR(finite impulse response) filter and smoother are introduced for discrete time-invariant state-space models with driving noises. The FIR structure not only quarantees the BIBO stability and the robustness to parameter changes but also improves the filter divergence problem. It is shown that the impulse responses of the FIR filter and the smoother are obtained by Riccati-type difference equations and that they are to be time-invariant and reduced to very simple forms. For implementational purpose, recursive forms of the FIR filler and smoother are derived with each other used as the adjoint variable.

The device that we are developing is a microprocessor-based, portable arrhythmia monitor that ultimately will need processing algorithm similar to those found now in monitoring systems in the cardiac care unit of today's hospital. Our initial goal is to replace the functions of the Holter tape recorder, the current device of choice for determining if an ambulatory patient has potential heart disease.

This paper describes the design of portable arrhythmia monitor and associated algorithm for automated diagnosis based-on micro-computer in the ambulatory ECG recording, analysis, and transmitting to a hospital host computer immediately through the telephone system.

Power plants are being met by integrating more functions into fewer displays and control devices. The trend toward more efficient man/machine interface, together with developments in distributed type systems, could lead to simplicity of the control benchboard.

The transition diagram, as well as the regular expression, can be used as a formal description for a language acceptable by a finite automaton or for the behavior of a sequential switching circuit. But, if we are given one of these two descriptions, we shall find that it is not easy to get the other counterpart description. This paper is to show an easy method to find the equivalet regular expression from the transition diagram, by the aid of a graph-transformation technique.

Design of electronic circuit should be both economical and reliable. If we put weight on economy, reliability will be lessened vice versa. But in some cases, a Designer should do exact design looking down upon economy. Especially, in integrated circuit, we should design as exactly as possible without much tolerance. In my thesis, I have studied the method for the exact design without much consideration in economy, and I also have developed Monte carlo Simulation program which can be operated by new generation of pseudo random number. Here, in my study, I have found out that new generation of pseudo random number was much more superior to any methods suggested by orthers.

An asymptotic solution of electro-magnetic waves diffracted by a dielectric wedge of the angle larger than $180^{\circ}$ is obtained in case of the incidence of a E-polarized plane wave. Based on the dual integral equation in the spectral domain, physical optics approximation is supplemented by correction currents distributed along the interfaces. Those currents are expanded in a series of Bessel functions, known as Neumann's expansion of which fractional order is chosen to satisfy the static edge condition as the limiting value of dynamic case. Numerical results of edge diffraction patterns and field patterns are presented for some typical cases.

The resonance frequency and the gain for oscillation of external cavity diode lasers are derived by approximating the phase and the gain conditions. By modifying single mode rate equations for the external cavity diode laser, steady state solutions and their stability are studied.
