Title: Controlling method of powder spraying device
Inventor: TSUNODA MASAHIKO
IPC: F27D3/18
Filed: 1983-02-01
Abstract: PURPOSE:To eject a prescribed volume of air from a lance pipe irrespectively of the change in operating conditions by opening a constant flow rate valve for compensation, at the same instant when immersion of a lance pipe is started, to increase the pressure in a powder vessel so that said pressure coincides with the pressure increase near a powder discharging device. CONSTITUTION:The moment when a descending lance pipe 9 arrives at the surface of a molten metal 10 is detected by a detector 13 which detects the position of the pipe 9. The signal thereof is fed to a control device 14. The device 14 opens a constant flow rate valve 6 for compensation by measuring the time elapsed after arrival of the pipe 9 at the liquid surface thereby increasing the pressure in a powder vessel 1. The driving device 3 of a powder discharging device 2 is driven at the same instant to start discharging the powder. The degree of immersion of the pipe 9 and the increase in the discharging rate of the powder are controlled according to the program inputted preliminarily in the control device. The increase in the degree of immersion of the pipe 9 and the powder discharging rate is stopped by the device 14 and the valve 6 is closed when said values attain a prescribed value after a specified time.

Abstract: PURPOSE:To effectively automatically restart many hysteresis motors after a power source is recovered by detecting a counter-electromotive force of a common section of the motors at the time of a power interruption, resetting the output frequency of a VVVF inverter, and operating the inverter with the frequency at the time of recovery of the power source. CONSTITUTION:A power source interruption is detected by a power source interruption detector 2 at the time of a power interruption, a power source interruption signal is output to a controller 3, and a VVVF inverter 1 is stopped. A counter-electromotive force of a common section of hysteresis motors 4a, 4n is input to a counter-electromotive force detector 6 through a transformer 14, and a rotating speed obtained by the detector 6 is output to a frequency setter. At the time of recovery from the power source interruption, the signal is eliminated, and the inverter 1 is operated without load. An average current vector difference detector 5 judges whether an abnormal signal is detected or not. If the abnormal signal is not detected, a switch 10 is applied by an application signal from a load application controller thereby to automatically restart it.

Title: Method for rolling
Inventor: MITO YOSHIAKI
IPC: B21B27/00
Filed: 1989-01-25
Abstract: PURPOSE:To make a rolling load small and to reduce surface ruggedness and wear of a work roll by forming many recessed parts on the surface of a rolling work roll and performing rolling with a fluid being shut in the recessed parts. CONSTITUTION:Many spherical recessed parts 6 are formed on the surface of work rolls 1, 2. A rolled stock 01 is rolled while filling the parts 6 with a fluid 5 from nozzles 3, 4. In a contact arc (c), the fluid 5 in the parts 6 generates a pressure being enough to plastically deform the stock 01 to support the stock 01 and to form a fluid boundary film. As an area ratio of bounding frictional region is smaller, a frictional shearing stress is made to be smaller and the parts 6 effectively act. Lubricating oil, a mixture of water and lubricating oil, water, and a fused salt are used as the fluid 5. A rolling load is reduced and a rolling mill is miniaturized because friction coefficient during rolling is reduced; surface ruggedness and wear of the rolls 1, 2 are also reduced.

IPC: H02M3/155
Filed: 1983-01-31
Abstract: PURPOSE:To enable to readily increase the control range by performing a pulse width control and a frequency control on the basis of a common control signal. CONSTITUTION:A diode 30 is connected between the collector of a control transistor 15 and one input terminal of a control pulse forming comparator 9, and a triangular voltage period controller 33 having a series circuit of a diode 31 and a resistor 32 is connected between one end of a capacitor 18 and the collector of the transistor 15.

Thus, the frequency is maintained substantially constantly, and the pulse width modulation can be performed. To reduce the output voltage, the resistance of the transistor 15 is reduced if the level of the control signal decreases, and the period of the control pulse from the comparator 9 is lengthened.

Abstract: PURPOSE:To improve responsiveness by determining orientation directions of liquid crystal cells so that the direction of distinct vision is opposite to the direction of an observer and is within right and left ranges of about 30 deg. with respect to the center line viewed from the direction of the observer. CONSTITUTION:With respect to orientation directions of liquid crystal cells 6 and 7 and the direction of distinct vision, liquid crystal cells 6 and 7 are subjected to orientation treatment so that the direction of distinct vision is 12:00 as shown in the figure.

Title: Spectacle lens
Inventor: EGAWA MASARU
IPC: G02C7/06
Filed: 1978-02-13
Abstract: PURPOSE: To obtain a comfortable field of view by so forming the lens that curvatures become smaller in lower region and become larger in upper region as the intersecting line group that the plane perpendicular to the main meridian assumes goes away from the main meridian and the perpendicular components of prism quantity are nearly constant near the circular intersecting line.  
     CONSTITUTION: A far vision part F, progressive focus part P and near vision part N are provided along the main meridian MM' in nearly the central longitudinal direction of a progressive focus lens for farsighted glasses. At the point A, the circular intersecting line consisting of the plane intersecting at a right angle to the line MM' and a refracting face exists. In the F region, the curvature is larger as it goes away from the line MM' and in the N region the curvature becomes conversely smaller and therefore the distortions of the entire part of the lens may be minimized. Since the perpendicular components of prism are constant near the circular intersecting line intersecting perpendicularly at the A point with the line MM' on the refracting plane, the images with which fluctuations are difficult to feel as against the lateral changes of the eyeballs may be obtained.
