Title: Multi-stand continuous drawing and rolling method for metallic pipe
Inventor: HIRAKAWA TOMOYUKI
IPC: B21B37/00
Filed: 1985-03-22
Abstract: PURPOSE:To decrease the generation of a square bulge on an inside surface by controlling the circumferential speed of rolls so as to increase or decrease the stretch of a metallic pipe, namely so as to generate a relative speed between the circumferential speeds of the rolls and the speed of the pipe. CONSTITUTION:The pipe is meshed with the respective stands of a stretch reducer body 1 for, for example, 5-stand rolling. The rolling load during rolling, the torque of each stand and the rolling speed of the pipe are measured by load meters 2, torque meters 3 and speedometers 4 and the information thereon are fed to a computer 6. The rotating speeds of the rolls are measured by roll rotating speedometers 5 and are fed to the computer 6. The computer 6 determines the controlled variable of the number of revolutions of the rolls by the signal fed therefrom and feeds an output signal to the body 1 to control the circumferential speeds of the rolls so as to increase or decrease the stretch (tension) of the metallic pipe, thereby decreasing the generation of the square bulge on the inside surface.

Abstract: PROBLEM TO BE SOLVED: To quickly and accurately move a target for fixation to a position corresponding to the part to be photographed for each purpose. SOLUTION: If an affection is detected in the fundus oculi Er during funduscopy, an examinant guides the line of sight of the eye E to be examined by use of a display position indicating part 26 and a liquid-crystal display part 19 to cause the line of sight to move within the observation range of an image of the fundus oculi in order to take the most effective image of the fundus oculi for diagnosis. After the photographic range of the image of the fundus oculi has been determined, a photographing switch 25 is depressed to input the output of the photographing switch 25 to a function control part 24, which in turn causes a mirror 5 to move back to a position indicated by the broken line, while causing a photographic light source 12 to emit light to record the image of the fundus oculi on film 6.

Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To obtain a process for controlling the density of the oxygen precipitation nucleation centers in single crystal silicon.  
     SOLUTION: In the process for controlling the density of the oxygen precipitation nucleation centers in the single crystal silicon, the single crystal silicon is annealed at least at 350°C and during this annealing step, the single crystal silicon is heated (or cooled) to a first temp. of T 1  of about 350 to about 500°C and thereafter, this temp. is increased from T 1  to second temp. T 2  of about 500 to about 750°C in order to form the oxygen precipitation nucleation centers in the single crystal silicon. The average rate of increase of the temp. from T 1  to T 2  is about <25°C per minute. The annealing is terminated at a point in time when the oxygen precipitation nucleation centers are capable of being dissolved by heat-treating the silicon at a temp. not in excess of about 1150°C.

Abstract: PURPOSE:To enable to obtain greater dynamic range even at the input of large signal with a simple constitution, by combining two diode series connections and two diode and resistor circuits. CONSTITUTION:D18, 19 are connected in series to the diodes D7, 8 as automatic gain control, and the series circuits of D20 and resistor 21, and D23 and resistor 22 are respectively connected parallelly. The voltage-current characteristics are respectively the curves (a) and (b), to the combination of Ds7, 8 and D20 and resistor 21. As to two types of circuits, the characteristics are parallel circuit of both the curves, but when the input signal is small, they are approximated to the curve (a), and the output signal has good linearity and obtains sufficient gain. When the input signal is great, the curve (b) is dominant, and operation is made around the point B, and the linearity is good with the characteristics of the resistor 21 shown in the curve (c). Further, the curve (d) shows the characteristics of D20. Thus, even at the input of large signal, the dynamic range can be taken greater.

Filed: 1990-03-07
Abstract: PURPOSE:To prevent the superposition of an error by providing plural latches, and fixing data by one of the latches and outputting data from the other multistage latches in response to a clock. CONSTITUTION:The output of an inverter IR 8 is connected to the input of the IR 12 through a transmission gate 10, and the output of the IR 12 is connected to the input of the IR 13, and the output of the IR 13 is connected to an output terminal 14, and a latch circuit is constituted. Besides, the output of the IR 13 is fed back to the input of the IR 12 through the transmission gate 11. In the preceding stage of the latch circuit, the latch circuit operating at the same timing and of the same configuration is provided, and when the clock phiA contained in a non-superposed two-phase clock is given, it responds to its trailing edge, and fixes the read data. Next, when the clock phiB is impressed to the latch circuit of the above-mentioned poststage, the fixed data is outputted from the output terminal 14. Then, the hold period of the fixed data becomes longer, and the temporal allowance of a data changed point and an input data fixed point becomes larger. Thus, even if the latch circuits are connected into a multistage, the error can be prevented from being superposed.

Consequently, even when rainwater flapped by a wind blows in from the narrow clearance Z between the lower end of the external wall panel and the cut-off material 5 functioning as the molding material in combination, a wind is introduced from an extremely narrow clearance X between the lower side frame of the external wall panel and the cut-off material 5 functioning as the molding material in combination little by little, thus quickly decreasing the speed of the wind in a wide space Y between the external wall material of the external wall panel having no frame and the cut-off material 5 functioning as the molding material in combination. Accordingly, rainwater flapped by the wind falls by its own weight.
