Title: Stainless steel with limited impurity concentration
Inventor: TETSUI TOSHIMITSU
IPC: C22C38/40
Filed: 1996-11-12
Abstract: PROBLEM TO BE SOLVED: To obtain ferritic and austenitic stainless steels suitably used for a member of a boiler, etc., to be used at high temp. for a long time, and having low σ-phase forming velocity by controlling respective concentrations of the elements existing as impurities, particularly O, Al, and Si. SOLUTION: In these ferritic and austenitic stainless steels, the concentrations of O, Al, and Si are controlled to, by weight, <=5ppm, <=50ppm, and <=400ppm, respectively. O is an impurity element accelerating the formation of σ-phase and σ-phase forming velocity can be decreased by reducing the concentration of O. Although the formation of σ-phase can be inhibited when O concentration is <=50ppm, remarkable inhibiting effect cannot be produced when it exceeds 50ppm. As to Al, its function and the reason of the limitation of its concentration are the same as in the case of O. Although Si is an impurity element accelerating the formation of σ-phase, its effect is smaller than those of O and Al. The reduction in Si concentration, however, can decrease σ-phase forming velocity.  Although O concentration of <=400ppm suffices for the formation of σ-phase because the effect of O is small, remarkable inhibiting effect cannot be produced when its concentration exceeds 400ppm.

Title: Digital signal exchange processor
Inventor: SHIMIZU FUMIHIKO
IPC: H04Q3/52
Filed: 1990-11-07
Abstract: PURPOSE:To guarantee bit synchronization or word synchronization between input and output with a simple configuration by arranging signal processing devices in a matrix of M lines and N rows and respectively connecting triangular input and output phase adjusting sections to the top and bottom of the (M-1)th and (N-1)th rows. CONSTITUTION:In this exchange processor, 8X8 selection switches (with eight expansion inputs-outputs) are basically used as signal processing device (switches) D and a signal processing section 31 is constituted by cascade- connecting the devices D in a matrix of 4X4. An input phase adjusting section 32 is constituted to a lower triangle matrix structure by respectively cascade- connecting one to three switches D to the 2nd- to 4th-line input sections and an output phase adjusting section 3 is also similarly constituted to an upper triangle matrix structure. Therefore, word synchronization can be guaranteed between the input and output even when paths from inputs 1-4 to outputs 1-4 are different from each other, since the number of devices through which signals are passed does not change.

Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To cancel the offset that is caused by a 2nd current when the collector-emitter withstand voltage of a transistor TR is set at a low level and no input signal exists by setting a 1st current to compensate the base current of the relevant TR and accordingly securing the same voltage drop level between the 1st and 2nd resistors. SOLUTION: One of both ends of a resistor 6 of resistance value R1 is connected to an IC terminal 3 of a signal source 1 with the other end of the resistor 6 connected to one of both ends of a resistor 7 of resistance value R2 respectively. Meanwhile, the other end of the resistor 7 is connected to a voltage source 8 of a bias circuit 30. Then a current of current value IC is supplied to the circuit 30 to compensate the base current of a TR 9 which flows into/out of the connecting point of both resistors 6 and 7. The relation of R1/R2=|(IC-IB)/ IB| is secured between the current value IC and the current value IB which flows into/out of the connecting point of the terminal 3 and a differential input buffer 32 where the negative feedback is applied to one of its both input terminals. As a result, the base current is compensated for the TR 9.

Abstract: PURPOSE:To prevent drawn flaws from being generated and to improve the quality and yield by arranging 2nd pinch rolls on the upper stream of 1st pinch rolls and obtaining through each pinch roll the back tension to the excessive tension generated the instant that a strip is wound round a mandrel. CONSTITUTION:Immediately after the tip of the strip 3 passes the 2nd pinch rolls 6 and then the 1st pinch rolls 4, the rotation of the 2nd pinch rolls 6 is controlled to be reduced, and then immediately the rotation of the 1st pinch rolls 4 is controlled to be reduced.

Abstract: PURPOSE:To prevent a shaft from floating up and consequently integrally mold the shaft precisely at the center of a molded item by a method wherein molten resin is also poured on the shaft, which is to be assembled to the molded item, simultaneously with the pouring of the molten resin in a cavity. CONSTITUTION:Molten resin is filled through a sprue part 28 and runners 32 into a mold cavity 30. At this time, a shaft 10 tends to shift upwards by buoyancy applied thereto. However, a part of the molten resin reaches the upper end of the shaft 10 through the sprue part 28 and a resin path 40, resulting in applying injection pressure on the upper end of the shaft 10. Accordingly, the shaft 10 is pressed down so as to be precisely centered to a permanent magnet 12. Under the state just mentioned above, molding is done, resulting in integrally joining the shaft 10 and the permanent magnet 12.
