In a state of separating a front end face of an air injecting nozzle 23 from a worked work W by a predetermined interval h, the air injecting nozzle 23 is moved at a constant speed in an X axis direction, injects air from an injecting hole 27a of a nozzle main body 27 and is moved to pass centers O1, O2 of worked holes Wb, Wc of the work W. A variation in a pressure is measured by a pressure measuring unit 30. X axis coordinates of the centers O1, O2 of the holes Wb, Wc, a hole diameter E and a center interval distance D1 are calculated based on coordinates of center points T1, T2 of inclined portions Ld, Lu of a curve Lx of the pressure relative to the measured X axis coordinate.

A taper correcting apparatus for a grinding machine comprises: workpiece supporting means for supporting a workpiece in parallel with a grinding wheel spindle; a cutting and feeding device which moves back and forth a cylindrical grinding wheel with respect to said workpiece; a wheel slide which is attached to a bed so as to be movable back and forth with respect to said workpiece; a pair of grinding wheel bearing pedestals which rotatably support ends of said grinding wheel spindle via bearings with respect to said wheel slide, respectively; a first grinding wheel bearing pedestal support which is fixed to said wheel slide, and which clampingly supports one of said grinding wheel bearing pedestals; a second grinding wheel bearing pedestal support which is attached so as to be rotatable about a round shaft, and which clampingly supports another one of said grinding wheel bearing pedestals, said round shaft being attached below said grinding wheel spindle to said wheel slide in parallel with the center line of said workpiece; a pressurring device which presses said second grinding wheel bearing pedestal support to rotate said second grinding wheel bearing pedestal support about said round shaft, thereby changing a distance between a center of said grinding wheel spindle and a center of said workpiece; and controlling means for controlling a pressing amount of said pressurring device, so that parallelism between a center line of said workpiece and a center line of said grinding wheel spindle is corrected.

An HTML (Hyper Text Markup Language) file processing method of the invention comprises: specifying a character string not influencing a display at a user terminal in an HTML file received from another server according to a request from the user terminal by referring to a definition data storage storing data for specifying the character string not influencing the display at the user terminal; and changing the HTML file so as to reduce data amount in accordance with a method corresponding to an attribute of the specified character string, and transmitting the changed HTML file to the user terminal. As stated above, because the data amount of the HTML file is reduced by performing the processing with respect to the character string not influencing the display at the user terminal, the user at the user terminal is unconscious of the performance of the method according to this invention, and the smooth communication of the Web page data including the HTML file becomes possible. Besides, because the data amount is reduced, the communication charge can also be reduced.

In the tool change device, a tool change arm 27 for changing a tool 25 with respect to a main spindle 24, a main tool magazine 29 including a plurality of hold grooves 30 arranged linearly for holding the tools 25, and a tool storage member 41 including at least one storage portion 46 for storing the tool 25 are arranged in the back-and-forth direction of the tool change device. In order that the tools 25 can be delivered between the tool change arm 27 and main tool magazine 29, between the main tool magazine 29 and tool storage member 41, and between the tool storage member 41 and tool change arm 27, a single tool loader L is disposed in such a manner that it can be moved in correspondence to the tool change arm 27, main tool magazine 29 and tool storage member 41.

A reception unit for providing data supplied from a serial input circuit to an inner bus and a transmission unit for providing the data supplied from the inner bus to a serial output circuit hold at least two sorts of control procedures among HDLC procedure, BI-SYNC procedure and start-stop synchronous procedure as control procedures for data transmission/reception, and the control procedures held by these units can be selected alternatively based on a command of the processor.

A data processor has an execution unit, an instruction register in which macro instructions having a register field are set for specifying registers in the execution unit, a micro ROM in which micro instructions containing a register instruction field are set, a first decoder for decoding the register specification data from the instruction register, a second decoder for decoding the register specification data from the micro ROM, and a selector for selecting either of the output of the first decoder or that of the second decoder corresponding to the selection signals provided from the micro ROM and thus producing data for specifying the registers. In this data processor having such a configuration, the decodings of the two register specification data described above are carried out substantially in parallel and a high-speed operation is thus made possible.

A data memory system includes a plurality of buffer regions each having a constant size so that serial data may be stored by linking the buffer regions. A descripter provided to correspond to each of the buffer regions includes memory region addressing information indicating the head address of the corresponding buffer region, data delimiting information indicating whether or not the data to be stored is terminated in the corresponding buffer region, and chain information indicating the head address of a next subsequent descripter.
