Title: Shelf device of refrigerator
Inventor: ARIMA KATSUHIKO
IPC: F25D25/02
Filed: 1990-06-12
Abstract: PURPOSE:To prevent a rightward or a leftward inclination of a shelf, enable the shelf to be moved with a low force and prevent a shelf device from hindering a storing of food at a lower part of it by a method wherein a geared shaft fixed to a spur gear connected under an operation of an electric motor is rotated and the shelf and a frame are moved up or down. CONSTITUTION:When a control switch 6 is turned on, a spur gear 5 connected to a shaft of an electric motor 7 is rotated and at the same time a geared shaft 4 fixed to the spur gear is rotated and concurrently another spur gear at the other end is also rotated so as to cause a shelf 1 and a frame 2 to be moved up or down. With such an arrangement, the shelf and the frame are moved up or down while being kept horizontal by the spur gears which are rotated or moved up or down on the right and left racks 13b. Since the sliding member 3 moving up or down within the sliding groove 13a can be smoothly slid without being inclined, no substantial load is applied to the electric motor. Due to this fact, a movement of the shelf can be performed only with an operation of the control switch, so that it is possible to make a small-sized device for moving the shelf for the electric motor or the like. The moving device does not hinder a storing of food at the lower part.

Abstract: PURPOSE:To repeatedly change the light path length of split light without providing a reciprocal movement mechanism, by rotating the optical system having a plurality of reflective surfaces provided on the light path between a beam splitter and a fixed reflective mirror. CONSTITUTION:A beam splitter 11 for splitting incident beam IR into two luminous fluxes, a fixed reflective mirror 12 for reflecting reflected beams from the beam splitter 11 to allow the same to be again incident to said splitter 11 and reflective mirrors 14, 15, arranged on a rotary stand 13 for reflecting transmitted beams to allow the same to be incident to a fixed reflective mirror 16 are provided. Two kinds of beams again incident to the splitter 11 from the fixed reflective mirrors 12, 16 are interfered and the interfered beam IL is allowed to irradiate a specimen. When the rotary stand 13 is rotated to one direction, the light path length between the splitter 11 and the fixed mirror 16 is changed. By this mechanism, the reciprocal movement of an optical system is unnecessary and the light path length of beam split by the splitter can be varied.

Filed: 1987-06-19
Abstract: PURPOSE:To exactly detect the bending of a sub-lance used for a converter by providing a light emitting device and light receiving device in the holder of the sub-lance at an arbitrary spacing and measuring the position of the light receiving part which receives the light from the light emitting device. CONSTITUTION:The sub-lance 6, the holder part 6a of which is inserted into the hollow part 5a of a probe part 5 having a sensor 9 for measuring the temp. and C content of molten iron at the front end part, is put into the converter to measure the temp. and C concn. of the molten iron. The above-mentioned measurement function loses the exactness if this sub-lance is bent by the high temp. in the converter and, therefore, the bending of the sub-lance needs be detected at all times. A bending detector consisting of the light emitting part 13 and the light receiving part 14 is, therefore, mounted in the holder part 6a of the sub-lance 6 and is covered by a protective cover 15. Many optical fibers 17 of an extremely small diameter are arranged regularly in the frame body 22 of the light receiving part 14. The ray from the light emitting part 13 is received in the position deviated from the central point O of the X-Y coordinates of the optical fibers in the light receiving part 14 if the holder part 6a bends by the effect of the high temp. The bending of the holder part of the sub-lance is thus detected from said position.
