Title: Controlling method for rolling work for pipe
Inventor: YAMADA TAKEO
IPC: B21B17/02
Filed: 1978-12-27
Abstract: PURPOSE:To contrive the uniformization of thickness distribution along the longitude of the finished pipe, by keeping the peripheral speed of each reducing roll at the reference peripheral speed or lower before biting the tip of the pipe blank, and by gradually increasing the peripheral speed after biting the tip of pipe blank. CONSTITUTION:The mandrel 2 is inserted into the pipe blank 1; under this condition, the pipe blank 1 is rolled with the reducing rolls 31a-38a. In this case, before the tip of the pipe blank 1 is bitten into rolls 31a-38a, the peripheral speed of reducing rolls 31a-38a is previously set at the reference peripheral speed or lower with the controller 4. After the tip of the pipe blank 1 is bitten into rolls, the peripheral speed of each reducing rolls 31a-38a is successively increased up to the reference peripheral speed. That is, at biting the tip of the pipe blank 1, the compression force is impressed on the tip of the pipe blank 1 longitudinally, in order to restrain the tendency of thinning the wall thickness. Accordingly, the degree of thinning of wall thickness at the tip of the pipe blank 1 is greatly improved, which in its turn improves the yield of the product.

Abstract: PURPOSE:To improve the damage quantity measurement accuracy by calculating the frequency distribution area of an ultrasonic wave surface wave in a material to be inspected and comparing the area with master data which is generated previously. CONSTITUTION:If the material 11 to be inspected is fatigued, the surface wave of the ultrasonic wave which is sent by a transmitter 3 and propagated along the surface layer part of the material 1 to be inspected is scattered or reflected because of variation of the molecular structure of the fatigue part and the remainder is sent to an ultrasonic wave transmitter receiver 5 through a receiver 4.

Abstract: PROBLEM TO BE SOLVED: To obtain a skin lotion having an effect comparable to or exceeding an extract derived from an animal by containing an extract of seeds of a family Leguminosae plant and an extract of a family Lamiacea plant. SOLUTION: This skin lotion contains an extract from seeds of Lupinus albus L. as a family Leguminosae plant and an extract from Thymus vulgaris L. as a family Lamiacea plant as active components. The preparation contains 0.1-50wt.% in total amount of both extracts and is prepared to creamy, an ointmentlike, a milky lotion-like, a gel-like, filmy or a liquid-like. A highly polymerized protein contained in the Lupinus albus L. exhibits a tightening effect for skin and makes the surface of skin smooth by forming a film on the skin. Flavonoid or tannin contained in the Thymus vulgaris L. promotes hydroxylation of proline or lysine important in transforming procollagen to collagen and assists reconstruction of a tissue by an anti-elastin action.  Therefore, the preparation exhibits a tightening effect for skin, reducing depth of wrinkle on the skin and further reducing microscopic undulations on the skin, then smoothing the skin.

Filed: 1980-11-21
Abstract: PURPOSE:To realize the monitoring for the power supply of a motor valve without adding any new relay nor any cable, by making use of a device which is used for the monitoring of the open/close state of the motor valve. CONSTITUTION:In case when the driving power supply of a motor valve is missed, the power supplies of auxiliary relays 8 and 9 are obtained via a transformer 7. Thus these power supplies are also missed in the same way as the motor valve, and the relays 8 and 9 are not energized with contacts 10 and 11 opened. Accordingly the missing of the power supply is decided for the motor valve in case when both contacts 10 and 11 are opened and stored in a storage function 16 of a state monitor device 14. Then the output decided by a deciding function 15 that decides the state of the present contact is compared with the output of the function 16 by a comparing function 17. In such way, the monitoring is possible not only for the open/close state of the motor valve but the missing of the power supply of the valve.
