Inventor: HIRAI KIYOSHI
IPC: E04B9/30
Filed: 1993-01-12
Abstract: PURPOSE:To reduce the volume of a roof panel in the case of transportation and moreover labor at the site. CONSTITUTION:In the case where an eave soffit material. 24 is attached to the front eave part 11 of a roof panel 20 through a hanging member 30, the basic end part 31 of the hanging member 30 whose middle part 32 is bendable is previously rotatably attached to the roof panel 20 in a workshop. The hanging member 30 is paralleled to the back of the roof panel 20 by rotating it for reducing the volume of the roof panel in the case of transportation. In addition, since both the ends of the hanging member 30 are fixed to the roof panel 20 by bending the middle part 32, though the basic end part 31 is rotatable, the hanging member 30 is automatically controlled in its rotation and wholly fixed only by fixing a tip part 35.

Title: Position detector
Inventor: ABE KUNIHIRO
IPC: G01B7/00
Filed: 1982-01-13
Abstract: PURPOSE:To obtain detection sensitivity which is less influence by temperature and clearance by fitting a magnet and a magnetism sensing element to one side of an L-shaped magnetic circuit, providing the 2nd magnet to the other side, and applying the magnetism sensing element with a magnetic field which is zero or negative while magnetism is not detected. CONSTITUTION:The magnetism sensing element 2 and magnet 4 are fitted to the horizontal part and vertical part of the L-shaped magnetic circuit 1 and the magnet 5 is fitted to the opposite back side. Magnetic fields to be applied to the element 2 by pieces of magnetic flux by the magnets 4 and 5 are denoted as phi1 and phi2. When there is no body 3 to be detected, those magnetic fields to the element 2 are balanced completely or in a slidghtly negative state to obtain an initial condition shown in a figure A. When the body 3 to be detected is put closer, phi1>phi2 and a high value is obtained as shown in a figure B. With such a slice level that the magnetic fields are nearly balanced, the output voltage of the element 2 is 0 and a little influence of temperature is exerted. In this case, the zero magnetic field point is close to the value of the magnetic field A of the element 2 when there is no body to be detected, and the influence of clearance is hardly exerted. Thus, stable detection sensitivity is secured.
