In an air path portion arranged within the machine frame, there is provided means for opening or closing through an electric signal and the air path between the air ejecting unit and the means is made shorter, whereby the response to air ejection is improved, the pressure loss during air flow is reduced to a minimum, and jet air is accurately applied to punching chips (leavings) which adhere to the punch at the bottom dead center for peeling off the punch.

Abstract: An object of the present invention is to provide an apparatus for manufacturing a stacked type electronic part which can manufacture a stacked type electronic part dried at low temperature for a product by increasing a manufacturing speed. A base plate is placed in a predetermined linear section path to be moved back and forth and be moved vertically. Above the section path are juxtaposed one or more insulator layer forming means discharging an insulating resin paste, conductor layer forming means jetting a conductor paste by an ink jet system and drying means drying the pastes. A thin film layer having a predetermined conductor pattern placed on an insulator layer while the base plate is moved back and forth one or more times. Those steps are repeated to form a stacked type electronic part.

Abstract: A method for accurately determining a center of target marks provided on a workpiece. The method involves imaging, at an imaging station, a circular target mark associated with the workpiece. A signal produced by the imaging operation is binary-encoding, in an image processor, and displayed on a monitor screen connected to said image processor. Starting points X1 and X2 of a different level of intensity are detected by scanning in one of either an X-axis direction or a Y-axis direction on a center of a cursor (shown on the monitor screen) when the center of the cursor is within the target mark. Other starting points Y1 and Y2 of a different level of intensity are detected by scanning in another of the X-axis direction or the Y-axis direction on a mid-point of coordinates of the starting points X1 and X2.

Abstract: Disclosed is an air motor having an engine pack (with a rotor provided with front and rear retainers, a stator, and vanes) which can be assembled and replaced even by an unskilled person. An air supply joint is engaged with guide projections formed on the inner peripheral surface of a housing, with its forward end portion held in contact with the rear retainer; the forward end portion being fastened by a nut member which is threadedly engaged with the housing. On the rear face of the forward end portion are formed a plurality of first projections produced of a rigid synthetic resin, and on the front face of the nut member corresponding to the first projection are formed a plurality of second projections, so that a firm relation of engagement is established by an elastic force of restoration of the first projection; that is, the nut member will not accidentally become loose owing to the locking effect of the first and second projections.
