Abstract: Provided is a work machine control system which enables a worker to perform a work more easily in the vicinity of a work machine executing a task automatically. A work machine control system comprises: a work machine that executes a task automatically as a work to be executed; and a task control device for controlling execution of the task. The work machine comprises a vehicle body control device and a hydraulic actuator used for executing the task, wherein the vehicle body control device comprises: a task content input section for receiving input of task content information; a movement control section for calculating a speed instruction of the hydraulic actuator based on the task content information; a receiving section for receiving task control information outputted from the task control device having a task control input section for receiving input of the task control information; and a task control section for controlling execution of the task based on the task control information.

Abstract: In an optical imprinting method, after pressing a mold with a mold pressing mechanism detachably holding a mold against a resist applied to a transferred body to firmly attach the mold to the transferred body and detaching the mold from the mold pressing mechanism, arranging a UV light source above the up side surface of the laminated body of the mold and irradiating UV light to cure the resist. Then, after completing the resist curing, retracting the mold and the transferred body from the UV light source and separating the mold from the transferred body.

Abstract: This invention relates to a work edge detection mechanism that enables an edge of a work to be viewed clearly through an aligning camera without adding an illumination device, and to a work transfer mechanism that uses the work edge detection mechanism. The work edge detection mechanism formed from a tubular body provided with an opening at one end thereof, the tubular body having a blocking member provided at the other end thereof, includes light-reflecting means on a lower surface side of the blocking member in order to reflect any light entering from the opening, is constructed so that the tubular body has an inside diameter (?1) at the opening of the tubular body and an inside diameter (?2) at a side of the blocking member, the inside diameter (?2) being greater than the inside diameter (?1), and enables vacuum suction transfer of the work.

Abstract: There is provided a method for spin coating, by which a resist is coated on a surface of a circular disc with a hole formed in its center. A method for spin coating coats a film-forming material discharged from a nozzle to an upper surface of a circular disc substrate with a through hole formed in a center while rotating the substrate. At an initial discharging stage where a discharge amount fluctuates, an inner diameter center of the nozzle is located at an initial discharge radius position apart from a position corresponding to a coat boundary of the disc substrate at an outer radial side. At a subsequent stage of stabilized discharging amount, the inner diameter center of the nozzle is moved from the initial discharge radius position to a stabilized discharge radius position around the coat boundary to further discharge the film-forming material.

Abstract: Spots of a resist are deposited in a concentric pattern on both sides of an annular disk. A motor which rotates the disk has a rotating shaft that can be inserted into or removed from a through-hole in the disk. Two ink-jet heads provided on the obverse and reverse sides, respectively, of the disk substrate are provided such that the heads are not in contact with the sides. A carriage for causing the two ink-jet heads to move radially inward or outward with respect to the disk substrate is also provided. The ink-jet heads are moved by the carriage while the disk is rotated by the motor to apply the spots of the resist.

Abstract: A rolling bearing, in which at least one of the races and a rolling element of the rolling bearing is made of a raw steel which is free from a Al.sub.2 O.sub.3 or an Al.sub.2 O.sub.3 -base inclusion particle with a 13 .mu.m or more average particle size; but which includes 80 or less Al.sub.2 O.sub.3 or Al.sub.2 O.sub.3 -base inclusion particles with a 3 .mu.m or more average particle size for each tested area of 165 mm.sup.2. The rolling bearing provides a very long life rolling bearing even under the severe conditions of a high bearing, the presence of a deflection in a bearing housing, defective lubrication, etc.
