There is provided a deep hole processing device for forming a hole by rotational movement of a main spindle to which a tool is attached of a portal machine toward a workpiece, having, a bush having a hole diameter for guiding rotational movement of the tool, and a bush holding unit provided on a cross rail capable of moving on columns of the portal machine for holding the bush with respect to a spindle head on which the main spindle is mounted at a predetermined distance, wherein a position of the bush relative to the workpiece and a pressure at which the bush is pressed against the workpiece may be controlled by movement of the cross rail.

When a groove having a section of Christmas tree shape for fitting the blade legs of a turbine is to be generated in the outer circumference of a turbine shaft by cutting work, cutting blades cut that groove by moving them gradually in a direction perpendicular to an axis parallel to female groove center line while rotating them on the axis. Three wide portions are cut one by one. A method for that grooving work includes a first cutting step of cutting a slope portion, an outer circumference portion and an undercut portion by using a first cutting tool, and a second cutting step of cutting a constricted portion by using a second cutting tool.

Grooving work method and grooving work apparatus

Working machinery for working an elongated work comprises a work stocker configured to store a plurality of works, a work carrying-in machine configured to carry in the works from the work stocker to a working area, a positioning device configured to position the work in the working area, a work clamper provided in the working area and configured to clamp the work in a vertical direction, a plurality of working machines arranged on both sides of the working clamper to work the elongated work from both sides of the work, a plurality of driving devices configured to move the working machines respectively in a longitudinal direction, a controller configured to control the working machines and the driving device, and a work carrying-out machine configured to carry out the work which is completed in working from the working area.

Working machinery for elongated work

There is a sorting apparatus for mixed envelopes according to whether or not the envelopes are face-up, and whether or not they are upside-down. Each envelope is carried lengthwise and a parallel light beam is radiated on the envelope from the right and left oblique directions with respect to the carrying direction of the envelope. When the light beam is radiated on the backside of the envelope from the upper side of the envelope, the shadow of the flap is formed on the envelope. Whether or not the envelope is face-up and whether or not the envelope is rightside-up is determined by this shadow detection.

Sheet orienter using flap detection

A position determining mechanism for a magnetic head utilizes a plurality of steps of varying thickness formed on a rotatable disk to set the position of a magnetic head, e.g. in relation to tracks of a magnetic tape. Steps of the disk are selectively positioned between a member attached to the magnetic head and a fixed position reference surface, with the disk being normally held pressed between the magnetic head mounting member and the reference surface by a spring and being made free to rotate when the magnetic head mounting member is pulled apart from the position reference surface by a solenoid, to enable the disk to be rotated to select a step of different thickness for determining a different position of the magnetic head.

Magnetic head position determining mechanism

A letter sorting machine (LSM) system of the invention has a plurality of LSMs, each having a feeder, a reader, horizontal convey paths, bins with a push-out mechanism, an elevator mechanism, a separating mechanism for separating the postal matter from the trays, a destination label printer, and a bundling machine. These LSMs are connected to a centralized system controller. The centralized system controller has a computer and a magnetic disk for storing a schedule for determining the mode of each LSM. The computer reads out the schedule table from the magnetic disk and controls the modes of the LSM for performing the primary or secondary sortation according to the kinds and amount of the postal matter to be sorted.

Sorter system for postal matter

An apparatus for sorting postal matter or mail to a plurality of stacking bins arranged in a row in accordance with the result of optically scanning and reading ZIP codes and taking out the mail from the stacking bins to a conveyance section arranged along the row of stacking bins whenever a predetermined amount of mail is stacked in a stacking bin. When the sorting operation has come to an end, the mail sorting apparatus detects if there exists any mail on the conveyance section, and takes out the mail from the stacking bins which are opposite to the empty region on the conveyance section downstream the position where mail is on the conveyance path. After the conveyance section moves and there is an empty region opposite to the stacking bin, it then takes out the mail from the stacking bin which was opposite to the position where there was mail. This method is repeated until all mail is removed from the stacking bins.
