Title: Alignment device
Inventor: UMAGOME KAMITAKA
IPC: H01L21/027
Filed: 1989-03-03
Abstract: PURPOSE:To simplify the structure of an alignment optical system and to cope with a change in mark position by separating a diffracted beam of 0th order and a diffracted beam of high order, which are generated by an alignment mark by irradiation with a light beam, through an objective system, and guiding them to a photoelectric detector. CONSTITUTION:The alignment mark RM is composed of a diffraction grating and the objective system consisting of an objective 21A, a bifocal element 21B, etc., moves corresponding to the change in the mark position; and light information from the alignment mark is sent to a phase detection system 40 through the objective optical system. When the diffracted beam of 0th order (regularly reflected light) and diffracted beam of high order (e.g. primary light) of the light information generated by the alignment mark are guided to a phase detector 40 through the objective optical system, the objective optical system is moved and controlled within the range wherein the diffracted beam of 0th order and the diffracted beam of high order are separated from each other at the light beam waist position BW of a light transmission side or at a nearly conjugate nearby position. Therefore, the need for a special optical path length correction optical system is eliminated.

Title: Columnar material
Inventor: ANDO YUICHI
IPC: E04C3/42
Filed: 1995-02-15
Abstract: PURPOSE: To increase a buckling resisting strength, to reduce weight, and to facilitate and ensure connection with the other member by a method wherein a hollow part is partitioned and a reinforcing member is longitudinally arranged, and during connection with other member, the reinforcing member is processed to form a tenon. CONSTITUTION: A hollow part 3 is arranged at the interior and the weight corresponding to the hollow part 3 is reduced, total weight is reduced, and conveyance and handling are facilitated. Besides, a reinforcing member 4 extending in the longitudinal direction of a columnar material 1 is arranged at the interior, and a strength against a compression load when the reinforcing member is used as a column is increased. Moreover, the reinforcing member 4 has the hollow parts 3 partitioned from each other, and peripheral wall parts 2 are coupled together between the hollow parts 3 to improve integral properties on a whole. Thus, a high buckling resisting strength as the columnar material 1 is provided.  Further, since the reinforcing member 4 is arranged throughout the longitudinal direction of the columnar material 1, when the columnar material 1 and other member are connected together, even when the columnar material 1 is cut in any position, the reinforcing member 4 is located at the end part. This constitution forms a tenon by using a reinforcing member at an end part and facilitates formation of connection structure with other member.

Title: Optical connector
Inventor: SUZUKI NORIO
IPC: G02B6/32
Filed: 1988-03-04
Abstract: PURPOSE:To eliminate a need of complicated optical axis adjustment and to obtain a high coupling efficiency by closely bringing end parts of a pair of optical fibers into contact with converging rod lenses respectively to support them and supporting at least one optical fiber freely attachably to and detachably from the converging rod lens and freely turnably. CONSTITUTION:Since optical fibers 1 which are so supported that they are closely brought into contact with converging rod lenses 2 are supported freely turnably to converging rod lenses 2, optical fibers 1 generally supported with slight decentering are turned to perform such adjustment that a maximum coupling efficiency is obtained. Since optical fibers 1 are supported freely attachably to and detachably from converging rod lenses 2, contacting end faces of optical fibers 1 or converging rod lenses 2 are prevented from being flawed when optical fibers 1 are turned to converging rod lenses 2. Thus, a high optical coupling efficiency is obtained without complicated optical axis adjustment.
