Abstract: A grinding method of a crank pin that grinds an outer circumferential surface of the crank pin of a crankshaft having a crank journal and the crank pin eccentric to the crank journal by rotating a crankshaft around a central axis (a center of the journal) of the crank journal and moving a rotating grinding wheel in a diametric direction of the crankshaft according to rotation phase angle of the crankshaft, in which a rotation number of the crankshaft is changed in one revolution of the crankshaft to perform a grinding process.

Abstract: A grinding method comprises steps of simultaneously grinding plural grinding portions of a workpiece by plural grinding wheels T1, T2 moved individually each other, and terminating said grinding by a predetermined grinding wheel T1 prior to a termination of said grinding by the other grinding wheel T2. Whereby, a content of the grinding by each grinding wheel T1, T2 can be same. A grinding condition in each grinding by each grinding wheel T1, T2 can be changed in accordance with a measuring result of the grinding portion in the grinding.

Abstract: A machining apparatus for machining a workpiece by moving a tool in direction relative to the workpiece comprises, tool moving means for moving the tool in the direction relative to the workpiece, tool movable range setting means for setting a movable range for the tool to inhibit the workplace from exceeding a reference size by inputting the reference size, and halting means for halting a movement of the tool when a position of said tool exceeds the tool movable range set by said tool movable range setting means.

Abstract: A numerically controlled grinding machine of the present invention grinds a cylindrical surface of a workpiece by a relative movement between the workpiece and a grinding wheel. The grinding conditions such as a grinding method and a finishing diameter of the workpiece are inputted so that data necessary for grinding the Workpiece are automatically determined in dependence upon the grinding conditions. The automatically determined grinding data are displayed on a display means. The grinding data displayed on the display means are modified by one of the four rules of arithmetic. The modification are carried out in accordance with a compensation rate set by override switch and the like or a compensation value inputted by a key operation.

Abstract: A spindle apparatus for supporting and rotating a workpiece in a grinder. The spindle apparatus includes a workpiece spindle rotatably supported on a spindle head and driven for rotation by a motor, and a spindle plate mounted to the front end of the workpiece spindle and including an eccentric drive pin. The workpiece spindle has a bore in which a ram is axially movable. A center is fit in the front end of the ram. A unit is provided to advance the ram to engage with one end of the workpiece when the workpiece is to be supported. A rotary sleeve is rotatably supported on the front end of the ram and includes an engagement portion which is displaceable in the axial direction of the spindle and engageable with the drive pin in the direction of rotation. A driving unit is mounted to the front of the rotary sleeve to engage the workpiece in the direction of rotation when the ram is in its advanced position to thereby transmit rotation.

Abstract: An image reading apparatus for repeatedly reading an image of a fixed manuscript by reading the fixed manuscript line-by-line in a first direction and scanning in a second direction each line of the fixed manuscript. The image reading apparatus also repeatedly reads an image of a moving manuscript. The moving manuscript is transferred from a manuscript supplying section also in the first direction and each line of the moving manuscript is also scanned in the second direction. The image information read by the scanning of the moving manuscript in the second direction is memorized in the sequential read order and then is read-out in an order opposite to that of the sequential read order. The image information read by scanning the fixed manuscript in the second direction may be memorized in the sequential read order.

Abstract: An original table is provided on which an original is placed. This original on the original table is scanned by a first optical unit. A conveyance path, constituting an auto document feeder, is provided near the table, and one side of the original moving on the conveyance path is scanned by the first optical unit and the other side of the original is scanned by a second optical unit disposed near the first optical unit. The scanned output of the first optical unit is stored in a memory which can delay its content by a time corresponding to the distance between the first and second optical units. The signal stored in this memory and the scanned output of the second optical unit are sequentially outputted.

Abstract: An image scanning section has an optical system for scanning an original in a two-dimensional manner, and a photoelectric converter for converting an optical image obtained by the optical system into an electrical signal. A binary coding section performs simple binary coding of the electrical signal supplied from the photoelectric converter in such a manner as not to accompany pseudo-gray scale coding, and performs pseudo-gray scale binary coding of the electrical signal supplied from the photoelectric converter in such a manner as to accompany pseudo-gray scale coding. An area designating section designates an area on the original. A scanning mode designating section designates image scanning modes within and outside an area designated by the area designating section and has at least a first scanning mode designating section which does not accompany pseudo-gray scale coding and a second scanning mode designating section which accompanies pseudo-gray scale coding.
