Title: Floor heating panel
Inventor: MASUGUCHI YOSHITSUGU
IPC: F24D13/02
Filed: 1986-02-25
Abstract: PURPOSE:To prevent inter layer peeling-off of a floor board and its warping by providing a frame member on the upper peripheral face of a wooden base member and fixing on to the frame member a wooden intermediate board which is arranged on a metal plate and at the same time striking fixing nails from the intermediate board through long holes in the metal plate into the base member. CONSTITUTION:A frame member 2 is mounted on the periphery of a wooden base member 11, and a metal plate 5 is placed inside of the frame member 2 and on the upper face of the base member 1. The metal plate 5 has a heat generating body on its lower face and long holes 4 formed in it. An intermediate board 6 that is arranged on the upper side of the metal plate 5 is fixed on the frame member 2 and at the same time fixing nails 7 are struck into the base member 1 from the intermediate board through the long holes 4 to place a surface member 8 on the intermediate board 6. With heat generation from the heat generating body elongation and contraction take place between the metal plate and the wooden base member 1 and between the intermediate board 6 and the surface member 8. Even if there is a difference in the metal plate and base member and in the intermediate board and surface member will not reach other sections because the fixing nails slide along the long holes, and if there is a difference in elongations or contractions of the metal plate and base member and of the intermediate board and surface member, there is no possibility of having inter layer peeling-off or warping.

Title: Displacement sensor
Inventor: SEKII HIROSHI
IPC: G01B11/00
Filed: 1992-01-30
Abstract: PURPOSE:To make it possible to detect, by a linear output, even displacement of a substance to be measured which has a specular surface by a method wherein the optical axis is tilted to the surface of the substance, a reflected light is sensed through a pinhole and a light-sensing surface is disposed in parallel to the optical axis of a detection light. CONSTITUTION:A light emitted from LD 3 is applied onto a surface 4M at different angles as represented by projection beams 21 and 22 and it is focused on the surface 4M of a substance 4 to be measured which is located at a position indicated by a mark M. When the substance 4 is displaced, the projection beams 21 and 22 are reflected on surfaces 4L, 4M and 4N of the substance 4 and become reflection beams 21L, 21M and 21N and 22L, 22M and 22N respectively. A part surrounded by the reflection beams 21L and 22N herein is an area wherein a reflected light exists at whichever position of L, M or N the substance 4 is located. A pinhole 11 is provided in this area and the reflected light enters PSD 7 in the form of a slender beam. The PSD 7 measures the centroid of the incident beam and can detect the position of the beam even when the beam is expanded.

Title: Power focus limiter
Inventor: EGUCHI HARUKI
IPC: G02B7/09
Filed: 1992-01-30
Abstract: PURPOSE:To improve operability when a focusing enable range is set and to enable the setting while a finder is viewed by motor-driving a movable limiter, which sets the moving enable range of an adjustment lens, forward and backward. CONSTITUTION:The focus limiter(ring) 12 driven by a motor 11 is mounted on an interchangeable lens L. When a focus limiter driving switch 13 is operated, the motor 11 is driven forward and backward through a motor driving circuit 14. Then, the limiter ring 12 is rotated and moved by receiving the forward and backward rotation of the motor 11 and the focusing enable range(focus limiter range) by a focusing lens 15 is changed. It is changed by changing the focusing enable range toward a short distance side with an infinity photographing distance as a reference. Thus, the focus limiter is made powerful and an operator can set the focusing enable range without viewing aside from the finder.
