IPC: B22D47/02
Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To surely hold out a casting even if a casting line is meandered by calculating sprue size and sprue position with an image pickup means arranged above the sprue, discriminating whether the sprue can be held out or not, and also, positioning a sprue holding tool. SOLUTION: After pouring molten metal, a sand mold M is carried by one pitch with a carrying device 1 and stopped below a camera 16. The image of the upper surface of the sand mold M is picked up with the camera 16. The image pickup result is picture-processed to calculate the size and the position of the sprue 8 with a control device. It is discriminated whether the sprue 3 can be held out or not from the size of the sprue 3. The sand mold M is sent to the carrying device 1 and come to the hold-out position at the finish end. At the time of enabling the hold-out, a traverse device 14 is worked and the position of a hold-out device 4 is made to coincide with the sprue 3. A travelling device 12 is worked and a sprue hook 10 is inserted into the sand mold M from the front face side of the sand mold M and the casting W is held up.  It is unnecessary to arrange the projection for holding out in the casting W and thus, the good yield to the product is obtd. Since the casting is held out from the finish end part, reaction force is small.

Filed: 1985-02-18
Abstract: PURPOSE:To reduce the thickness of the device by constituting the device so that the thickness of the magnetic disc recording/reproducing device is not restricted with the pressing arm.

Abstract: PURPOSE: To reduce the dv/dt applied to the auxiliary thyristor by connecting the anode of the auxiliary thyristor to the connection between the resistance and the capacitor of the CR absorber circuit coincided to the dv/dt rating of the main thyristor.  
     CONSTITUTION: The CR absorber circuit containing resistance R 4  and capacitor C 3  connected at the anode and cathode sides each is provided to main thyristor SM, and the time constant is set comparatively small in accordance with the dv/dt of thyristor SM. When the main thyristor is turned off via the commutating means, the voltage featuring the positive anode polarity and the negative cathode polarity emerges with the changing ratio dv/dt reduced by the absorber circuit. The dv/dt is reduced greatly for above mentioned auxiliary thyristor SA since its area between the anode and the cathode is connected to both sides of capacitor C 3  via the gate of SM. Thus, the misignition can be prevented even with the small dv/dt of SA.
