Title: Metal molding device for molten metal casting
Inventor: SAKAKIBARA TATSUO
IPC: B22C9/06
Filed: 1979-10-23
Abstract: PURPOSE: To improve working efficiency and enable the products having no differences in quality to be obtained by providing a common pouring port and a sealing part to a lower mold forming plural cavities and forming excess metal spaces communicating the respective cavities.  
     CONSTITUTION: A recess 3 deeper than the insertion depth of a sealing part 5 with an upper mold 2 is formed to a lower mold 1 having plural cavities 4, to form an excess metal space 6 communicating the cavities 4. Molten metal is poured through the recess 3 of the lower mold 1 to fill the cavities 4 with the molten metal. The upper mold 2 is moved downward to insert the sealing part 5 into the recess 3 and pressurize the molten metal in the cavities 4. At this time, the molten metal in respective cavity 4 is pressed uniformly by way of the excess metal space 6. Thence, if the pressing force of the upper mold 2 is made constant and hydrostatic high pressure is applied, the molten metal in the cavities 4 decreases its volume while accompanying squeezing solidification and the molten metal is successively forced into the cavities by the downward movement of the upper molde 2 following this up, whereby the product of homogeneous and dense construction is obtained.

Abstract: PURPOSE:To attain the quick traverse of a tape in both directions and the switching of the tape driving direction by means of two electromagnetic mechanisms, by providing the 1st and 2nd mobile members which can have reciprocating movements in parallel to each other and a tape direction switch member which moves forward in the same direction together with both mobile members. CONSTITUTION:When the fast forwarding of a tape is desired to the left, for example, during a record or reproduction mode, the 1st changeover switch 50 is operated for energization of the 1st electromagnetic mechanism 43. Thus the 1st mobile member 8 is moved forward. As a result, the tape is quickly traversed in the left direction. When the tape is intended to traverse quickly in the right direction, the 2nd electromagnetic mechanism 44 is energized by the 2nd changeover switch 51 to move forward the 2nd mobile member 9. When the driving direction of the tape is switched, both switches 50 and 51 are operated for simultaneous energization of both mechanisms 43 and 44. Thus both members 8 and 9 are moved simultaneously forward.

Title: Floating point data processor
Inventor: NAKAJIYOU HISAO
IPC: G06F7/76
Filed: 1983-07-27
Abstract: PURPOSE:To speed up processing by setting floating point data to absolute zero forcibly if the data is nonnormalized data before use when the data is read out of a memory for processing. CONSTITUTION:Data read out of the memory is held in a data register 10. The most significant digit bit of the mantissa part of this fetched data is checked by a zero detector 11, which outputs logic 1 when this part is zero or logic 0 when not. When the output of an AND circuit 12 is logic 1, the output of a gate circuit 13 is all logic 0 and set to absolute 0 forcibly when the data is fetched for processing. Consequently, a check on whether the mantissa part of floating point data is normalized or not is omitted.

Title: Wire bonding method
Inventor: SHIBASAKA MITSUSADA
IPC: H01L21/60
Filed: 1984-07-02
Abstract: PURPOSE:To speed up bonding work by reducing the time of stopping a tool by a method wherein balls are formed while the tool is risen after finish of stitch bonding. CONSTITUTION:When the tool 1 is risen in the direction of an arrow (a), a wire 4 is drawn out of the tip of the tool 1 because a clamper 2 is opened. The clamper 2 is closed at the point of drawing the wire 4 by a length l and the tool 1 and the clamper 2 are risen, when the wire 4 is torn off.

Abstract: PURPOSE:To change a wide area into a single crystal by a method wherein energy beam intensity distribution is rendered roughly uniform and a part of the periphery of the beam cross section is kept oblique to the scanning direction. CONSTITUTION:With the cross section of a laser beam 15 convex along the direction of laser movement, the solidus-liquidus boundary surface 17 is consequentially convex at its central part along said direction. And the central part solidifies earlier than the flanks. A wide single crystal layer 16 is formed out of polycrystalline layers 16a and 16b that are much narrower. A laser beam 15' with an rectangular cross section is applied, oblique relative to the direction of scanning, the area covered by a first scan ahead of the area covered by a second scan. The solidus-liquidus boundary surface 17' solidifying first from the area covered by the first scan, a solidus grows accordingly in the single crystal layer 16 for the formation of a single crystal layer 16'. During the second scan, a polycrystalline layer 16'b is formed but under the scanned area and is very small in width. Repetition of this procedure results in efficient conversion of a desired area into a single crystal.
