Title: Parallel transmission optical module and its manufacture
Inventor: ITO MASATAKA
IPC: G02B6/10
Filed: 1989-02-21
Abstract: PURPOSE:To obtain the inexpensive parallel transmission optical module whose optical axis is easily adjusted by arranging the array of optical elements on a plane substrate and setting the incoming/outgoing direction of light vertically, and coupling the elements with optical fibers whose end surfaces are cut obliquely almost at 45 deg.. CONSTITUTION:Guide grooves 11 for positioning an optical fiber supporting part 10 are formed on the substrate 21. The guide grooves 11 are held at an accurate distance to an LED array 23 and machined by grinding in a V or right-angled shape. The optical fiber supporting part 10 has light coupling part cut by grinding, etc., at 45 deg., the light beam 13 from the LED array 23 which is transmitted through the clad part 15 of the optical fiber 26 is reflected totally by a core part 14, and its optical path is bent by 90 deg. to guide the light onto the substrate 21 in a parallel direction.

Title: Straightening method
Inventor: UENO SHIGEYASU
IPC: B21D3/00
Filed: 1978-04-12
Abstract: PURPOSE: To make possible the straightening at comparatively good accuracy, by detecting the amount of straightening for the material to be straightened before applying the straightening load, at straightening the material to be straightened, and by measuring the proportional factor of the material to be straightened, after applying a specified load.  
     CONSTITUTION: The straightening angle of the material to be straightened is 6 degrees, for instance; after releasing the load, a load equivalent to the point C for giving a deformation to the extent unexceedable above started straightening angle 6 degrees is applied to the material to be straightened; and then, the load is temporarily released and again is applied. By this procedure, (variation of deformation/ variation of load = proportional factor of the material to be straightened) can be easily detected for the span C-C' or C'-C. Moreover, by increasing the torque to be applied to the material to be straightened, and by releasing this twisting torque at the point D where (twisting angle - proportional factor × twisting torque) reaches above stated straightening angle, the straightening at high accuracy becomes possible.
