Title: Manufacture of laminated metal tube
Inventor: KOMIZO YUICHI
IPC: B21C37/06
Filed: 1988-04-05
Abstract: PURPOSE:To obtain the laminated tube metallurgically joining inner and outer tubes by interposing an amorphous metal layer between two metal sheets of different kinds, laminating by forming an amorphous metal layer on the end face in the width direction of the both sheets as well and heating with its resistance welding after forming it in a cylindrical shape. CONSTITUTION:The metal stripe sheet 1 becoming an inner tube and the metal strip sheet 2 becoming an outer tube are fed in the same direction under being opposed mutually. An amorphous layer is then formed by arranging plural thermal spraying nozzles 7 at one part or both parts of the end face and opposing face in the width direction of the both 1, 2. The both 1, 2 are then laminated in the thickness direction and formed in a cylindrical shape with the metal strip sheet 1 becoming an inner tube being made at the inner side and the end face of the metal strip sheet 1 becoming the inner tube and the metal strip sheet 2 becoming the outer tube is formed in a tubular body with its resistance welding.

Abstract: PURPOSE:To make an optical head device to be reloadable type by suppressing a returning light to a semiconductor laser by using a Faraday rotator, improving an optical utilizing rate by using the collimator lens of a large aperture number and forming a circular beam by using a beam shaping prism. CONSTITUTION:The outgoing light of a semiconductor laser 1 is transmitted through the Faraday rotator, which is composed of a garnet thick film 2 and a magnet 3, and an optical rotator 9 according to such an order to be mentioned. For the semiconductor laser 1, when an active layer is set so as to be coincident with a P polarizing direction, the elliptical cross section of the outgoing light and P polarization are obtained. This light is transmitted through the Faraday rotator and after that, a polarizing surface is revolved by 45 deg.. This light is transmitted through the optical rotator 9 and after that, the polarizing surface is revolved by 45 deg. in a reverse direction. Then, the light is returned to the P polarization. Since the minor axis direction of the elliptical shape and polarizing direction are coincident for this light, a beam diameter in the minor axis direction can be enlarged by using a beam shaping prism 10. Accordingly, it is not necessary to use the collimator lens of the small numerical aperture, which generates the lowering of the optical utilizing rate, and the high optical utilizing rate can be obtained.

Title: Clutch/brake interlocking apparatus for automobile
Inventor: IKEDA TOSHIO
IPC: B60W10/18
Filed: 1978-07-13
Abstract: PURPOSE: To accomplish smooth transmission by controlling the clutch at the depressing stage following intermittent movement thereof an intermediate depressing position of the pedal arm.  
     CONSTITUTION: Upon depressing of a pedal arm 2, a cam 10 turns to allow a lever 7 to be pushed up with a lift surface 10c of the cam 10 while a clutch cable 9 is pulled so that the clutch moves to the position at which it is disengaged completely. Thus, transmission is accomplished. On the other hand, even if the pedal arm 2 is depressed to the intermediate position, no brake is applied because an working rod 5a is connected with a play l. Under such a condition, further depressing  of the pedal brings the lever 7 into contact with a slide surface 10 of the cam 10.  Thus, the depressing of the pedal arm is made possible and the working rod 5a is  pushed thereby ensuring sufficient braking force.
