A control apparatus comprises a plurality of process units operating in accordance with parameters, a storing section for storing parameters relevant to processings by the process units, a touch screen for setting predetermined parameters for the process units, and a parameter administration section. The parameter administration section sends corresponding one of the stored parameters to one of the process units in reply to a request issued thereby, transfers the set parameter to the process uni...

A control system which comprises a reduction gear unit containing gears, a motor being disposed on an input side of said reduction gear unit, a sensor for detecting a turning angle of said motor, and control means for inputting output from said sensor and controlling turning of said motor. The control system further includes gear output angle variation estimation means for estimating a gear output angle variation of said reduction gear unit based on the motor turning angle. An angle transmission...

A control element for control functions within a passenger area of a vehicle having several turning knobs whose positions are indicated by an illumination display, includes an LED (Light Emitting Device) and a light-guide coupled directly with the LED and having a light-exit surface that is coupled with a light-entry surface leading to at least one turning knob, a light-conducting plate (7) adjacent the light-guide, and a housing. The light guide (4) is connected with the turning knob (2) and ha...

The invention relates to a control method and a control arrangement which comprises a feedforward power amplifier (10), which receives and amplifies a signal and which on amplifying the signal causes non-linearities to the signal. The control arrangement also comprises adjusting members (50, 80) and adaptation means (110, 130), which form an adaptation factor and control the operation of the adjusting means (50, 80) by means of the adaptation factor by adapting the amplitudes and phases of signa...

An incorrect operation is prevented from occurring in a tracking system for keeping track of a photographic object and taking a picture of the photographic object. When a body which is most likely to be recognized incorrectly as a photographic object exists, pan/tilt driving is carried out on a lens block employed in the tracking system so that an optical axis of the lens block is brought into the range of an angle set as an allowed-drive range. By doing so, the lens block will never take a pict...

A connection device allows for mounting a control panel in a manner such that the panel projects from the front lower edge of a control apparatus. According to the invention, optimum adjustment of the control panel relative to the front of the control apparatus is achieved in that the connection devices take the form of angle plates which are assembled from two leg parts and can be set and secured in a plurality of angular positions about an axis aligned parallel with the lower edge of the contr...

In a control method, the first controlled variable is made to coincide with a predetermined controlled variable set point. A relation variable representing the relationship between second controlled variables which are designated in advance from measured second controlled variables different from the first controlled variable so as to maintain a predetermined relationship is calculated. A control actuator is so controlled as to make the calculated relation variable coincide with a predetermined ...

Complex control procedures employ direct memory access by a first DMA processing unit 54 to send control data to a first controller by means of DMA channels 54.sub.-1 to 54.sub.-n, and by a second DMA processing unit 56 to send control data to a second controller 36 by means of DMA channels 56.sub.-1 to 56.sub.-m. The first DMA processing unit 54 also has a branching controller 52 as a DMA channel for transferring timing data to a second timer 40. When a time specified by the received timing dat...

A control unit, which divides a controlled system into a plurality of zones and carries out control of the individual zones separately, can match the timings for the zones to reach a steady-state reference temperature by basic control. It can effectively reduce overshoot and undershoot after reaching the steady-state reference temperature, and suitably control the temperature of a wafer in the fabrication process of semiconductor devices.

In an automotive vehicle, a shift in speed position is suppressed by increasing a hysteresis amount in vehicle speed between an shift-up vehicle speed and a shift-down vehicle speed when a periodic variation in engine output is effected under the control of a slip control unit, or by inhibiting a downshift for a predetermined length of time during the periodic variation in engine output effected under the control of the slip control unit.
