Title: Sorter
Inventor: INOUE MAKOTO
IPC: G01R31/26
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of erroneous sorting with a device for sorting objects to be measured in accordance with the results of measurement with a measuring instrument by controlling the opening and closing of the door of a passage comunicating with a specified place for housing the objects to be measured in accordance with the results of the measurement. SOLUTION: The manual sorter 1 is composed of the measuring instrument 2, a controller 3 and a switchgear 4. The measuring instrument 2 measures electrical characteristics of each product and lights a pilot lamp 2A in the case the results of the measurement are nondefective. A pilot lamp 2B is lighted in the case the results of the measurement arranged defective. The controller 3 is connected to the measuring instrument 2 and opens a solenoid valve 5 when a nondefective decision signal SGO is inputted to a set terminal. As a result, the air from an air source is supplied to the cylinder of a switching mechanism 4C which opens a switching plate 4C1 to the state of allowing the admission of universal semiconductor devices into an opening 4B1.  Namely, an operator is unable to put the universal semiconductor device into a housing box 4A for the non-defective unless the switching plate 4C1 opens and, therefore, the possibility of the erroneous sorting is eliminated.

IPC: H04N1/00
Filed: 1993-02-03
Abstract: PURPOSE:To provide a facsimile connection controller in which the connection or disconnection of a facsimile equipment can be easily attained. CONSTITUTION:A facsimile managing part 12b is equipped with the management information of each facsimile equipment connected with facsimile connecting parts 13a-13n. At the time of newly connecting the facsimile equipment, or disconnecting the already connected facsimile equipment, a control part 12a instructs the connection or disconnection of the facsimile equipment to the facsimile managing part 12b. In the case of the connecting instruction, the facsimile managing part 12b generates the management information corresponding to the facsimile connecting part of the facsimile equipment to be connected, and in the case of the disconnecting instruction, the facsimile managing part 12b cancels the management information corresponding to the facsimile connecting part of the facsimile equipment to be disconnected. Thus, the connection or disconnection of the facsimile equipment can be attained only by changing the management of software, so that this processing can be easily attained.

Title: Steel pipe sheet pile having outside surface projection
Inventor: TERASAKI SHIGEKI
IPC: E02D5/04
Filed: 1995-02-03
Abstract: PURPOSE: To prevent generation of a clearance between a joint member and a steel pipe, and secure a water stopping function as a steel pipe sheet pile wall by fixing the joint member to a steel plate bent in the same curvature with an outside diameter of the steel pipe, and fixing it to the steel pipe through a deformable filler. CONSTITUTION: A joint member 2 is fixed to a steel plate 3 bent in the same curvature with an outside diameter of a steel pipe 1 having an outside surface projection 5. Since a steel plate 3 is fixed to the steel pipe 1 through a deformable filler 4, even if the projection 5 exists, a clearance is not generated between the joint member 2 and the steel pipe 1, and a water stopping function as a steel pipe sheet pile wall is secured. A water swelling material is used as the deformable filler 4. The joint member 2 is fixed by bolts 12 penetrating through the steel plate 3, the filler 4 and the steel pipe 1. The projection 5 on an outside surface of the steel pipe 1 prevents dislocation between a steel pipe earth retaining wall and a reinforced concrete wall.
