Title: Splitting method for billet
Inventor: WATANABE TSUNEO
IPC: B23K7/00
Filed: 1978-05-10
Abstract: PURPOSE: To shorten the breadth of the splitted section, and to improve the producibility and yield, when the billet is to be splitted, by giving the angle of lead to the gas nozzles at upper and lower part of the billet, and the proceeding direction of the splitting work, by giving the offset to the centers of the gas nozzles from the middle of them, and then, by carrying out the splitting work.  
     CONSTITUTION: When the breadth of the billet 1 is to be splitted, the angles of lead θ 1 , θ 2 , are formed in the proceeding direction of the billet 1; the splitting gas  nozzles 2, 2', are fixedly arranged at upper and lower part of the billet 1, and besides, the centers 4 of nozzles 2, 2', are δ 1 , δ 2 , offset from their middle; hereby, the breadth of the traveling billet 1 is splitted. The angles of lead θ 1 , θ 2 , are preferable to be 5°W45°, and the offsets δ 1 , δ 2 , of the nozzle centers 4 are preferable to be 5W15mm. As a result, the gas streams from nozzles 2, 2', cross each other; however, the offsets δ 1 , δ 2 , of the nozzles 2, 2', prevent the collision of gas streams; hereby, the splitting chip is discharged passing through the splitting line 3 of the opposite nozzle. According to this method, the producibility is greatly improved without reducing the casting speed like as the conventional method, and also, the breadth of the splitting line is shortened, and the yield is imporved.

Title: Integrated circuit
Inventor: ISODA YUTAKA
IPC: H03K19/173
Filed: 1978-05-10
Abstract: PURPOSE:To make it possible to constitute arbitrarily a desired logical operation circuit by arranging circuit elements constituting the logical operation circuit individually and perfoming wirings among these circuit elements selectively as required. CONSTITUTION:Plural circuit element groups such as tri-state element TS, totem pole element (or pull-up resistance element) TP, gate element G and inverter element INV are formed on a wafer or a chip and are connected selectively to constitute an arbitrary logical operation circuit. For example, a totem pole output circuit is constituted by connecting G, TP and INV and taking out the output from the connection intermediate point between TP and INV, and an open collector output circuit is constituted by connecting G and INV and taking out the output from INV. Thus, logical operation circuits can be constituted arbitrarily, and a wide-range design is possible.

Title: Casing of centrifugal fan
Inventor: SHIKAUCHI NORIO
IPC: F04D29/44
Filed: 1996-02-20
Abstract: PROBLEM TO BE SOLVED: To suppress the reduction of pressure of discharge air at a discharge port and increase wind velocity and wind volume by forming a tapered face which is extended to a nose side in the inside on an anti-nose side of the discharge port in a casing of a centrifugal fan which is communicated with a small clearance part on the uppermost stream side on the nose side of the discharge port on the lowermost stream side. SOLUTION: A tapered face 3-1 which is extended to a side of a nose 2-2 is formed in the inside on an anti-nose side which is in proximity with a discharge port 2-4 in a casing 1 of a centrifugal fan, in particular, a centrifugal fan in which the discharge port is short. Consequently, it is possible to prevent abrupt expansion of a cross section of a passage in the vicinity of the short discharge port 2-4, stabilize a stream of air to be discharged, and suppress noise because area of a spiral passage 2 from a terminal part to an end of the discharge port 2-4 of the passage 2 is changed gently. Moreover, a straightening plate 4 may be provided in opposition to the tapered face 3-1 which is extended to the nose 2-2 side at the discharge port 2-4. In this case, it is possible to increase the maximum wind velocity further.

IPC: H03M1/76
Filed: 1993-03-16
Abstract: PURPOSE:To provide a D/A converter from which a highly accurate analog output is obtained, whose chip size is decreased and whose cost is reduced. CONSTITUTION:A 2nd D/A converter 12 is connected directly in parallel across a reference resistive element RM of a 1st D/A converter 11 to eliminate the need for a switch element used to connect the 1st D/A converter 11 and the 2nd D/A converter 12. Thus, a distortion component of an analog voltage is reduced and high accuracy is attained. Moreover, number of resistive elements of the 1st D/A converter 11 connected between one terminal of the reference resistive element RM and a point of a 1st reference potential Vcc and between the other terminal of the reference resistive element RM and a point of a 2nd reference potential Vss is selected in response to an output of a 1st decoder 11i. Thus, a size of a transistor (TR) forming a switch element does not give effect on the accuracy of the analog voltage, the size of the TR and a chip size are decreased and the cost is reduced.
