Title: Connection device for universal joint
Inventor: YOSHIDA TORU
IPC: F16D3/26
Filed: 1993-12-28
Abstract: PURPOSE:To ascertain and facilitate connection of outer and connection flanges of connection device in a universal joint, shorten a neck of the connection flange, improve strength and save a space. CONSTITUTION:Teeth 23, 23' each having a wedge-shaped section and grooves 24, 24' each having a reversed wedge-shaped section are continuously formed on opposed surfaces of an outer flange 21 of a universal joint and a connection flange 22 connected thereto, installed on an end of a propellant shaft. A flat spline 25 which is concentrically meshed is formed when the opposed surfaces are abutted with each other. The flat splines each composed of the wedge-shaped teeth and the reversed wedge-shaped grooves 24, 24' are combined. A key is inserted between the splines perpendicularly to the spline, to prevent dislocation of the cores of the splines. It is thus possible to dispense with a space th which bolts and nuts are inserted, and to reduce length of a neck of the connection flange.

Title: Apparatus and method for detection of defect in optical-fiber base material
Inventor: FURUTA SHIGEYUKI
IPC: G02B6/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide an apparatus and a method in which the position of a defect is detected three-dimensionally and precisely by a method wherein wide-width sheetlike light is used as detecting light as well as a light source, a detector and an optical-fiber base material are turned around the central axis of the base material. SOLUTION: A light source 2 emits sheetlike light 3 as detecting light whose width is wide in the length direction of an optical-fiber base material 1 and which is dispersive. Since the sheetlike light 3 is incident perpendicularly on the surface of the optical- fiber base material 1, it is not subjected to the influence of the refraction on the surface of the optical-fiber base material 1, and it is passed straight through inside the optical-fiber base material 1. A detector 5a and a detector 5b detect scattered light 4 generated at a time when the sheetlike light 3 hits a defect. A rotation-driving part 6 fixes the optical-fiber base material 1 at its head top part, and it turns the optical-fiber base material 1 at a prescribed rotational speed around the central axis O in the length direction.  In addition, the detectors 5a, 5b and the light source 2 are attached respectively to slide-driving parts 7a, 7b, 7c, and they move the detectors 5a, 5b and the light source 2 to the length direction of the optical-fiber base material 1 so as to be fixed to desired positions.

Title: Automatic ticket examination device
Inventor: IMATSUKA KATSUO
IPC: G07B15/00
Filed: 1998-12-15
Abstract: PROBLEM TO BE SOLVED: To easily specify a collected ticket when a processing for a different ticket becomes erroneous by installing a collected ticket holding part, temporarily holding the collected tickets just before they are collected by a ticket collection part or a different ticket collection part by means of a stopper or selectively distributing the tickets transported by a means of a transportation path for ticket collection to the ticket collection part or the different ticket collection part. SOLUTION: Relating to an automatic ticket examination device corresponding to plural tickets, the first ticket which is normally processed is held in a collective ticket holding part 29 installed just before a temporary ticket collection part 31. When a writing processing for the second ticket becomes erroneous, the collected ticket which is previously held in a collected ticket holding part 29 is carried to a different ticket collection part 32. The error ticket (second ticket) is discharged to a take-out port 3 and a fault content is transmitted to a clerk monitoring device. Thus, a station attendant can specify the collected ticket, passage judgement can be made from all the tickets that users supply and be can discriminate illegality.
