Abstract: Components (62-65) are consecutively taken out from a plurality of component feeders (52) which supply a multiplicity of components to a component feeding position (52a) in succession, transferred to a prescribed assembling position (54a, 154a, 157a), and assembled into a product (61), which is then transferred to and held in each of a multiplicity of holding recesses provided in a product storing means (53, 153). This method allows the components to be assembled into a product by a component assembling apparatus of compact and simple construction, as well as permits the assembled product to be held and carried in the holding recesses of the product storing means to the next step of the process.

Abstract: A machine tool of small scale, light weight, and low cost, yet accomplishing a high degree of precision in machining. A spindle (2) is encased in a body frame (1) and disposed preferably in such a manner that the spindle (2) is movable along an axial center thereof or Z-axis direction by means of a Z-axis moving means (4). Either Y-axis table (5) or an X-axis table (6), at least being capable of moving along X-axis or Y-axis direction, or both is provided at one end of the spindle (2) on one side of the body frame (1) and arranged to be vertical with respect to the axial center of the spindle (2).

Abstract: A parts arranger comprising a rotating disk (4) which has a plurality of part accommodating holes (6) for accommodating screws (5) arranged in a circumferential row or a plurality of concentric rows and is supported in a condition inclined at a predetermined angle .theta. relative to a horizontal plane, a circumference guide (7) which is disposed along an outer circumference of the rotating disk (4) so as to be substantially perpendicular to a surface of the rotating disk, and a stepping motor (1) which rotates the rotating disk (4) at a predetermined angle in a normal direction and then at a predetermined angle in a reverse direction.

Abstract: An exposure method for irradiating a mask from above the mask held in proximity to a substrate positioned below the mask to transfer a mask pattern of the mask to a photosensitive layer of the substrate by exposing the photosensitive layer to a light beam, includes the steps of using a gap-measuring device to measure a gap between a portion of the mask to be locally scanned and irradiated and a portion of the substrate to be locally irradiated, comparing a value measured by the gap-measuring device with a preset value, and locally deforming the mask and/or the substrate according to a difference between the value measured by the gap-measuring device and the preset value so as to cause the gap to approach a predetermined value.

Abstract: A component holder body is provided with a component arrangement section where an installation space for a component is defined, and holding parts for holding the component arranged in the installation space. The component arrangement section is constructed so as to be shiftable between a holding position in which the component arrangement section projects and a position projecting upward from the holding position. Meanwhile, the holding parts are designed so as to shift, in association with the shift of the component arrangement section between the holding and projecting positions, between a holding posture for holding the component and a retreat posture for opening the installation space.
