Title: Method for continuously casting active element-containing copper alloy
Inventor: HOSOKAWA FUMIHIRO
IPC: B22D11/00
Filed: 1997-02-05
Abstract: PROBLEM TO BE SOLVED: To add the active elements of Ti, Zr, Cr, Al, etc., in high yield and to obtain an ingot having high quality. SOLUTION: This casting method is constituted so as to flow molten copper 10 of low oxygen tapped from a melting so as to flow molten a trough 30, continuously add the active element 32 at a prescribed position in the trough 30 and to flow the molten copper alloy 11 after adding the active element 32 into a mold 50 through a tundish 40 to execute the continuous casting. In such a case, at least the surrounding of the molten copper alloy 11 after adding the active element is made to an Ar gas atmosphere. Therefore, since the surrounding of the molten copper alloy after adding the active element into the molten low oxygen copper, is made to the Ar gas atmosphere having non- activity with the active element, the adding yield of the active element is improved, and since oxide and nitride are not generated, the quality of the ingot is improved.

Title: Amplitude limit circuit
Inventor: SAWAMURA AKIRA
IPC: H03G11/00
Filed: 1991-01-23
Abstract: PURPOSE:To manufacture the amplitude limit circuit by a usual CMOS process so as to apply amplitude limit to both minimum and maximum signals uniformly. CONSTITUTION:When a voltage at an output terminal 5 is lower than an inverting input terminal 3, since an output of a comparator 18 goes to an H and an output of an inverter 19 goes to an L, a 1st analog switch 14 and a 4th analog switch 17 are turned off, and a 2nd analog switch 15 and a 3rd analog switch 16 are turned on. Thus, a back gate terminal of a P-channel MOSFET 13 is connected to an inverting input terminal 3 and a gate terminal is connected to an output terminal 5. Thus, when a voltage between the output terminal 5 and the inverting input terminal 3 reaches a threshold level Vth, a current flows to the output terminal 5 through the P-channel MOSFET 13 from the inverting input terminal 3. As a result, a minimum voltage of the output terminal 3 is limited to VB-Vth. Similarly when the voltage at the output terminal 5 is lower than the inverting input terminal 3, a maximum value of the voltage at the output terminal 5 is limited to VB-Vth.

Abstract: PURPOSE: To achieve the reduction in measurement time and the improvement in measurement accuracy by using a ring laser oscillator.  
     CONSTITUTION: A photo detector 12 and a prism 21 which is mounted with a reflecting film 23 for making the quantities of laser light 19 and reflected light 20 equal and gives a slight angle θ between the laser light 19 and reflected light 20 are combined to a ring laser oscillator consisting of total reflecting mirrors 14, 15, an output side mirror 16 drawing out laser light and a laser medium 17. As a result, the two laser lights 18, 19 of the same frequency are drawn out from the ring laser oscillator and the laser light 18 of the one side is reflected by the reflector 9 installed to the moving object under measurement to become reflected light 20 and is further reflected by the prism 21 to become reflected light 22. This reflected light 22 and the laser light 19 are then superposed and are radiated to the photo detector 12, by which the moving distance and direction of the moving object are measured. Hence, the highly accurate measurement is accomplished without requiring warm-up time.

Title: Convection heating utilizing forced swirling of air under pressure reduced and balanced condition
Inventor: KUBOYAMA NOBUYOSHI
IPC: F24J3/00
Filed: 1981-02-23
Abstract: PURPOSE:To make it possible to generate uniform distribution of a heated air current within a closed hollow chamber by a method wherein air in the closed hollow chamber is discharged outside the chamber by sucking the air forcibly through the rotation of a rotary member i.e. a pressure reducing operation, and frictional heat is generated by making use of the friction between the air and the rotary member, i.e. heat generating operation. CONSTITUTION:When a rotary vane 6 is rotated by a motor 5, a pressure reducing frictional heat generating mechanism X is operated so that the pressure of the air in the closed hollow chamber 1 is gradually reduced by the air sucking and discharging action of the rotary vane 6 and is brought under a balanced condition when the pressure difference between the air inside the chamber and the air outside the chamber reaches a pred termined value. Under the above balanced condition, an air stagnating phenomenon takes place in a region A in which the rotary vane 6 rotates so that the friction of the air with the rotary vane 6 is repeated continuously and the temperature of the air is elevated due to the friction heat. At the same time, a rotary impeller 7 of a follower rotary mechanism Y is rotated in the same direction as the direction of rotation of the rotary vane 6 due to a swirling air current effected by the rotary vane 6 and a stream of air designated by the arrow is generated by the rotation of another rotary vane 8 coaxial with the rotary impeller 7 so that the temperature of the air within the chamber 1 is elevated gradually.

Abstract: PURPOSE: To prevent the release of prestress by a method in which a PC pile in which plural stoppers are projectionally provided at proper intervals to the head part of PC steel bar is driven into the ground and then the head part of concrete of the pipe is chipped at a place higher than the stoppers at the lowest position.  
     CONSTITUTION: A stopper 6 is made up by forming male screw in the heat part of PC steel bar 1 and then screwing plural nuts at proper intervals on the male screw whose one side is fitted with a bearing plate. A PC pile A is driven into a given depth under the ground, the ground is excavated to form an excavated part (a), and then the head part of concrete of the pile is chipped at a place higher than the stopper 6 at the lowest position. In this case, since the stopper is projectionally provided, the movement of the PC steel bar 1 into the foundation can be prevented by the stopper 6 even when the contact part between the peripheral area near the heat part of the PC steel bar 1 and the concrete part is exfoliated. Thus, the release of prestress can be prevented.
