Abstract: PURPOSE:To prevent interference with a cradle roll when applying a half coil, by providing a plurality of stoppers with a reduced diameter in a wire coil automatic packer composed of a plurality of tucking-in arms constituted by a ring structure. CONSTITUTION:Tucking-in carriers 1, 2 are positioned at the retreated limit and tucking-in arm 8 is fully opened. The tucking-in carriers 1, 2 are moved forward and the tucking device is transferred to the endface of the cradle roll 5 to close the arm at the upper face position of the cradle roll 5. Subsequently, after the tucking-in arm 8 is contracted up to the upper face of the cradle roll 5, the tucking-in carriers 1, 2 cease to move forth and the tucking-in arm 8 opens fully and then a material is inserted in the inside of the wire coil 3. And the cradle roll 5 is rotated in the opened state of the tucking-in arm 8 up to non-interference position at the inner face of the wire coil 3. Finally the coil 3 is made flexible and the material is packed with the coil 3. And hence, a high grade winding-up on a material can be applied.

Title: Resistance-welded joint of material with high conductivity and its manufacture
Inventor: KAJIWARA RIYOUICHI
IPC: B23K20/00
Filed: 1982-03-03
Abstract: PURPOSE:To obtain the titled welded joint which has a joint part with invariable  stable strength while increasing electric resistance between joint members under high  pressure condition by using metal having greater electric resistance than a base material as a constituent component and forming an interposing alloy layer having a lower  melting point than the base material for jointing. CONSTITUTION:Metallic powder 2 which has high electric resistance and a high melting point and also has the lower melting point of alloy with base materials 1 and 1 to  be jointed than those of the base materials 1 and 1 is sandwiched in the joint interface  between the base materials 1 and 1. In this stage, pressure is applied by an electrode 4  on a pedestal 3 and an electrode coupled with a pressurized cylinder 5 and a pressurized shaft 6. In this case, Cu tube are used as the member 1 to be jointed and Ti  powder is used as the metallic powder 2 to perform pressure application and electricity feeding. Consequently, the metallic texture in the section of the joint part form the uniform joint part while Ti is melted completely. Namely, when the joint interface between Ti and Cu rises in temperature above 9,000 deg.C, a liquid layer of low-fusion-point alloy of Ti and Cu is formed and Cu in the liquid layer moves to the Ti side by diffusion to accelerate the melting of the Ti, thus obtaining the target resistance-welded joint of the material with high conductivity.

Title: Multibeam optical head
Inventor: WATABE AKINORI
IPC: G11B7/135
Filed: 1991-02-27
Abstract: PURPOSE:To concel a difference between focus positions of beams having different wavelength without using a high performance lens whose color aberration is corrected by correcting the aberration with using image surface curvature. CONSTITUTION:Light having wavelength at 830nm emitted from a semiconductor laser is made incident on an objective lens 4 and the recording surface of an optical disc 5 perpendicularly and forms a light spot on the recording surface of the optical disk 5. Light having wavelength at 780nm emitted from a second semiconductor laser forms a spot on the position apart from the objective lens by 0.5mum on the same path. Then, since the image surface curvature is 240h<2>mum, (h) is the height of an image (mm), the height of the image (h) is decided so that the curvature is equal to 0.5mum, thus, when inclination of the incident beam is 0 deg. 39', the focus positions are coincident with each other. By this method the need for using a composite lens whose color aberration is corrected is eliminated, and the miniaturization of the objective lens and the reduction in weight are attained.
