Patent number: 10195521Abstract: An information processing apparatus erases, on the basis of a chained state of a plurality of pieces arranged on a game field, the pieces in the chained state. The arrangement of the pieces in the game field is controlled such that, in a predetermined region on the game field, an odd number of pieces and an even number of pieces are alternately arranged on imaginary lines in an advancing direction on the game field. For example, the information processing apparatus erases a serial piece group formed as a chain by determining, starting from operation for any one piece on the imaginary line corresponding to a frontmost row among the imaginary lines, whether a piece of a same kind as the one piece is present in left and right pieces adjacent to the one piece present on a next imaginary line in the advancing direction from the operated one piece.Type: GrantFiled: January 27, 2016Date of Patent: February 5, 2019Assignees: Akatsuki Inc., BANDAI NAMCO Entertainment Inc.Inventors: Genki Shiota, Koji Tezuka, Kunio Hashimoto, Ken Kanai, Shohei Sekii

Patent number: 6086704Abstract: The invention is directed to a method of manufacturing an optical connector according to which it is possible to adjust a projection length a bare optical fiber (7) projects from a connection end surface (3) of a ferrule (1). At a step (a), an optical fiber cored line (5) is inserted through and attached to an optical fiber insertion hole (4) of the ferrule (1), and the bare optical fiber (7) and the ferrule (1) are bonded to each other by hardening a heat-hardening adhesive (11) at a first hardening temperature. Next, at a step (b), the connection end surface (3) is ground so that the connection end surface (3) becomes flat and flush with a tip surface of the bare optical fiber (7). Following this, at a step (c), the heat-hardening adhesive (11) is heated again to be hardened at a temperature which is higher than the first hardening temperature, so that a tip of the bare optical fiber (7), causing pistoning due to the reheat hardening, projects from the connection end surface (3).Type: GrantFiled: June 10, 1998Date of Patent: July 11, 2000Assignees: The Furukawa Electric Co. Ltd., Nippon Telegraph and Telephone CorporationInventors: Ken Kanai, Jun Yamakawa, Naoko Shimoji, Shinji Nagasawa

A front end surface (2) of a ferrule (1) comprises a flat surface (16) vertical to the central axes of optical fiber insertion holes (3) and a slanting surface (15). A step (17) is provided at the upper end of a slanting surface (15) and the flat surface (16) protrudes frontward by the step (17) with respect to the slanting surface (15). The optical fiber insertion holes (3) open at the slanting surface (16) and pin engagement holes (4) are provided on both sides of the optical fiber insertion holes (3).Type: GrantFiled: June 12, 1998Date of Patent: April 4, 2000Assignees: The Furukawa Electric Co.
