Filed: 1990-05-02
Abstract: PURPOSE:To obtain a heat insulating door for a refrigerator, which does not restrain the place of installation of the refrigerator, by connecting two sheets or more of heat insulating doors through hinges. CONSTITUTION:A heat insulating door 1 is constituted of two sheets of door pieces 1a, 1b connected pivotably to each other through a hinge 7 while the seal member 8 of soft urethane foam or the like, excellent in heat insulating property and prominent in the restoring property against compression, is mounted to one side of the connecting surfaces of the door pieces 1a, 1b. When the handle of the left side door piece 1b of the heat insulating door 1 constituted in such a manner is pulled to this side to open it and, then, the handle is pulled rightward successively, the door piece 1b is pivoted with respect to the door piece 1a about the supporting point of the hinge 7 and is opened to this side of rightward while being bent into the shape of a chevron. Accordingly, the door can be opened even when there is no room, corresponding to the width of the heat insulating door 1, in front of a refrigerator. When the heat insulating door 1 is closed, the seal member 8 prevents the leakage of cold air through a space between the door pieces 1a, 1b whereby the refrigerating performance of the refrigerator will never be deteriorated. Accordingly, a large-size refrigerator, whose heat insulating door can be opened and/or closed without any restriction in the place of installation, can be obtained.

IPC: G01N21/41
Filed: 1991-04-19
Abstract: PURPOSE:To simplify the constitution of a measuring apparatus, which measures the distribution of the refractive indexes at the cross section of an optical waveguide by an RNF method. CONSTITUTION:The apparatus for measuring refractive indexes by an RNF method has a projecting system and a light receiving part 5. The projecting system emits measuring luminous flux from one edge into an optical waveguide part 3, which is provided at one surface of a substrate part 2. The light receiving part 5 receives the luminous flux 4, which leaks from the optical waveguide part. The distribution of the refractive indexes at the cross section of the optical waveguide is measured based on the change in amount of the incident light into the light receiving part 5. The light receiving part 5 is arranged so as to shield the leaking luminous flux. The edge of the light receiving part on the side of the center is positioned in the leaking luminous flux so that the receiving part passes a part of the leaking luminous flux on the side of the center. The incident point of the measuring luminous flux is moved. The distribution of the refractive indexes is measured by obtaining the change in amount of the received light.

Title: Cable insulator layer step separating device
Inventor: SAKABA MASAHIRO
IPC: H02G1/12
Filed: 1995-05-15
Abstract: PURPOSE: To cut and remove each insulator layer in the shape of staircase, without giving any external damage to a lower layer of the insulator layers to be cut by arranging each cutting blade with an inclination to the cable inserting direction and shearing the lowest layer of the insulator layers to be cut with a rotating force of each cutting blade. CONSTITUTION: Since each cutting blade 5a, 5b is arranged with an inclination to the inserting direction of a cable 8, cutting is initiated in the direction of vector sum of the inserting force of cable 8 and rotating force of a cable guide 3. When the cutting blades 5a, 5b rotate integral with the cable guide 3, a distinctive friction force is generated between the end portions 29a, 29b of the blades 5a, 5b in the rotating side and the insulators 9a, 9b of the cable 8 in the fixed side. Therefore, the lowest layer of the insulators 9a, 9b to be cut with the shearing force by this friction force is sheared. The insulating layers 9a, 9b having been cut are pushed upward along the flat area in the front side of the rotating direction of the cutting blades 5a, 5b and are then exhausted from a window section.

Filed: 1987-05-14
Abstract: PURPOSE:To switch virtual spaces in nonprivileged without spoiling a protecting function among the virtual spaces by providing a means which has plural candidates to be employed as the value of a register stored with information of an address conversion table and which selects a candidate to be employed in nonprivileged mode. CONSTITUTION:Address conversion tables AT8 and AT9 are provided and a register (ATBR) table 10 determines which is used.
