Filed: 1987-06-02
Abstract: PURPOSE:To ensure a working space and improve an operation property and a maintenance property by installing in such a way that the shaft core of a bobbin holder makes an acute angle to a virtual line connecting the same place of each winder. CONSTITUTION:Winder W are installed in such a way that the shaft cores of bobbin holders 2, 3 make an acute angle to a virtual line which connects the same place of each winder W, with their operating sides being outwardly faced. Thereby, the adjacent winders W are shifted from each other by a defined quantity in the longitudinal direction and each operator can be positioned in the shifted place. In addition, since the bobbin holders 2, 3 of a winder W are obliquely positioned from a working face, the operating distance for an operator to the winder W is substantially reduced. Hence, a working space for the operation of yarn putting, removing entwined yarn, or replacing a traverse chip can be ensured improving an operation property and a maintenance property.

Title: Land inspecting apparatus for printed wiring board
Inventor: ARASE MASAYUKI
IPC: G01N21/88
Filed: 1989-05-31
Abstract: PURPOSE:To judge the pass or fail of a land without the effect of the part of a pattern by providing a land lead-out circuit, and inputting the outputs into length measuring circuits. CONSTITUTION:The reading pixels of a parallel reading circuit 4 are aligned in three lines for U, D, L and R. The length is formed of 16 pixels. The pixels constitute three lines of I, II and III. UD-C and LR-C are provided at the centers. The interval between the arms is separated by two picture elements. The resolu tion of an image sensing element 1 is determined so that the width of a pattern is about three pixels. The data of the arms U - R, UD-C and LR-C from the circuit 4 are inputted into a land lead-out circuit 5. The data of each of three lines are inputted into an AND gate as the data of each arm. Since a copper foil part is made to be '1' and a base material part is made to be '0', a copper foil is specified only when all three lines are '1'. The outputs of the circuit 5 are inputted into length measuring circuits 6A - 6D. The circuits 6A - 6D judge the distance from the starting point at the center C to a point where the copper foil is changed into the base material at first, based on the binary- coded image data of the arms U - R and the central bit. Thus the pass or fail of a land can be judged without the effect of the pattern part.

Abstract: PURPOSE: To avoid impact upon the opening and closing of a valve with a valve box transferred by an electric driving system for converting the rotation of a motor into reciprocation.  
     CONSTITUTION: When voltage is impressed to a DC motor 101, generated rotational force axially slides a driving ring 107 using a driving shaft 103, a flat gear portion 108b and a female thread portion 107a. When the ring 107 slides in direction A, an operating ring 40 slides in direction A counter to the force of a spring 43. This motion transfers a valve box 21 using a movable disc 31 and an insulating connecting member 26. Thereby, a clearance through which liquid flows is caused between a valve portion 3 and a valve seat 25. A driving ring 107 slides in counter- A direction to initial position through the change-over of impression voltage. Since the ring 40 is outside, change-over can be made to manual operation if any trouble has occurred to a driving system.

Abstract: PURPOSE: To provide an electric discharge machine that is able to enhance a removal rate, and also to prevent any drop in product accuracy in a workpiece from occurring. CONSTITUTION: This electro-discharge machining unit is provided with an automatic voltage regulating means being connected to a primary power source 41, and keeping the voltage of this primary power source 41 constant, a pulse generating means generating a pulse, a discharge voltage generating means generating the set waveform voltage on the basis of the voltage and the pulse made constant, and impressing each discharge voltage onto a workpiece 26 and an electrode 22, a voltage detecting means detecting the discharge voltage, and an abnormal discharge preventing means lengthening a span of quiescent time if the discharge voltage detected by the voltage detecting means is less than the setting value, respectively.  Since even if the voltage in the primary power source 41 becomes lowered, the discharge voltage will not go down at all, the abnormal discharge voltage preventing means will not operate at all unless there is abnormal discharge happening, therefore a span of machining time can be shortened in that degree.
