A system for controlling the speed of a DC motor so that the material fed to a rotary cutter is successively cut to desired lengths. The speed of the rotary cutter driving DC motor is controlled in accordance with a rotary cutter speed control pattern which is determined by the relation between the length of the rotary cutter circumference and the length to which the material is to be cut. This rotary cutter speed control pattern is provided in the form of speed command signals in accordance with a function output derived by setting the length of the rotary cutter circumference, the length to which the material is to be cut and the cutting distance during which the rotary cutter speed and the material travel speed synchronize with each other. The system also accomplishes the necessary control for correcting any error caused between the speed control pattern and the actual rotary cutter speed as well as the required acceleration control of the motor in accordance with the speed control pattern.

A control computer as a master apparatus in a control network system includes a packet generation unit. The packet generation unit: selects a control command for writing a data from among packet generation information; references the packet generation information for each of the selected control command; and includes a data for write which is read from an address in a storage section corresponding to the each control command, in a control packet to generate the control packet. A communication unit transmits the generated control packet to a controlled object as a slave device.

An image forming apparatus includes a plurality of sheet feed trays, a tray information management unit, a sheet feed control unit, and an image forming unit. The sheet feed trays contain recording sheets. The tray information management unit manages tray information in which tray identification information on the sheet feed trays is associated with sheet type information on sheet types of recording sheets contained in the sheet feed trays. The sheet feed control unit selects, from among the sheet feed trays, one sheet feed tray containing a recording sheet of one sheet type designated in an image forming request by referring to the tray information, and controls a sheet feeding operation for feeding the recording sheet from the selected tray. The image forming unit forms an image on the recording sheet fed from the selected tray according to image forming data input with the image forming request.

A motor controller having the electronic cam function that makes it smooth operation even if the number of operation patterns is lessened is provided. The electronic gear function included in a servo-amplifier and a divider are used to vary the gear ratio of an electronic gear in a previously provided ratio in accordance with an external rotation position so that the electronic cam function is realized. The motor controller further includes a program execution unit so that the electronic gear is operated in accordance with programs. Since the electronic gear function and the divider is included in an inexpensive servo-amplifier and is used to realize the electronic cam function, the inexpensive and intelligent system can be realized. Since the divider is provided in the system, the number of data and the reading frequency of the cam pattern can be decreased and accordingly the inexpensive system is realized.

A pulse noise canceler in which the sensibility of FM pulse noise detection is decreased when an FM wave exceeding the minimum bandwidth which is predetermined of an FM wave detector is input to the pulse noise canceler. In order to detect pulse noise from an output from the FM wave detector in an FM tuner to open a holding gate, an FM pulse noise detector is constituted by a high-pass filter, a variable control amplifier, a full wave detector, and the like. An over deviation detector is constituted by a signal meter for detecting a received field strength, an attenuator, and a high-pass filter, thereby detecting an over deviation level of the FM wave detector. This detection output from the over deviation detector is input to a bottom peak detector and becomes an over deviation signal. An over deviation signal from the over deviation detector is incorporated in the arrangement of a noise AGC amplifier in the FM pulse noise detector to influence control of the holding gate.
