A vertical machining center equipped with a rotary pallet changer, the center comprising a pallet clamp unit provided along the front face of the bed, with the clamp unit holding a pallet in a vertical position, and being capable of rotating around a horizontal axis. A rotary pallet changer provided in front of a front face of a bed of the vertical machining center, a saddle provided on an upper surface of the bed. The being saddle is slidable along the X axis, and a column is provided on a top surface of the saddle, with the column being slidable along the Y axis. A headstock is provided on a front face of the column with the headstock being slidable along the Z axis. A tool magazine and an automatic tool exchange device are arranged alongside the bed with a numerical control unit being provided for numerically controlling the saddle, the column, the headstock, the pallet clamp unit, the rotary pallet changer, the tool magazine and the automatic tool exchange device.
摘要:
An exposure apparatus that emits light toward a latent-image bearing member configured to bear a latent image, the latent image formed on the latent-image bearing member being used in a developing process performed by a developing device. The exposure apparatus includes a first light-emitting unit including an organic electroluminescence element disposed along a main scanning direction of the latent-image bearing member, the first light-emitting unit emitting light toward the latent-image bearing member, and a second light-emitting unit disposed along the main scanning direction, the second light-emitting unit correcting an amount of light to which the latent-image bearing member is exposed in cooperation with the first light-emitting unit.

A sheet processing apparatus includes a heater, an irradiation unit, and a contact unit. The irradiation unit irradiates a sheet with heat rays from the heater to heat the sheet by radiant heat. The contact unit includes a member that heats a region of the sheet by coming into contact with the radiant heated sheet on a downstream side of the irradiation unit. A part of the heat rays output from the heater is radiated onto a part of a structure constituting the contact unit to raise a temperature of the member.

In an electromagnetic switch device, a direction where a first plunger moves at the time a solenoid for pinion extrusion operates and a direction where a second plunger moves at the time a solenoid for motor energization operates are constituted in the same direction. A concave portion having a predetermined depth D is formed in a first fixed iron core used for the solenoid for pinion extrusion and a stopper member that controls a returning position of the second plunger is arranged therein. A part of the second plunger overlaps to the first fixed iron core in the axial direction.

A position measurement system for measuring positional coordinates of a point under measurement includes a first noise removal unit, a parameter determination unit and a second noise removal unit. The first noise removal unit removes noise from the measured positional coordinates to acquire first positional coordinate values. The parameter determination unit determines a noise removal parameter on a basis of the first positional coordinate values. The second noise removal unit again removes noise from the first positional coordinate values with using the noise removal parameter, to acquire second positional coordinate values.

摘要:
In a method for removing punched fragments in a workpiece formed using a punch and a die, the workpiece, which is tightly attached to a stripper, is lifted without extracting the punch from the perforations formed in the workpiece, subsequently pushing back the punch lifted from the die so as to make it protrude slightly from the bottommost end of the perforations, and performing an operation for removing punched fragments in that condition. The method for removing punched fragments can easily be performed even if only a very narrow space is available in a counterbore of a die, and can ensure that no punched fragments remain inside the perforations, and therefore can improve yield of a product being fabricated. A method for producing an article by punching inclusive of the method for removing the punched fragments is also disclosed herein.
