Title: Solid sensible heat recovery system employing heat accumulating material
Inventor: KOUTAKA IKUO
IPC: F28D17/00
Filed: 1977-10-31
Abstract: PURPOSE: To provide a solid sensible heat recovery system employing a heat accumulating material enabled to obtain recovery heat uniformly despite the variation of the treated layer of solids by surrounding a solid sensible heat recovery portion with said heat accumulating material.  
     CONSTITUTION: In the case of using the melted salt or the like utilizing latent heat to recovery the sensible heat of a slab 1, such a construction is made that heat absorbing tubes 2a and heat accumulating material 6 are arranged longitudinally and a solid sensible heat recovery portion 2 as heat absorbing wall is surrounded with said heat accumulating materials 6. Heat from said slab 1 is transmitted to said heat aborbing wall 2 through radiation, and a portion of radiant heat is used as latent heat for melting said heat accumulating material 6 or accumulated as sensible heat. Namely, when a large amount of salb is treated and melted salt is used, an increased amount of heat acculating material is melted. If a small amount of salb is treated, a decreased amount of heat accumlating material is melted, and the variation of the vaporization amount of heat medium in said solid sensible heat recovery portion is reduced. Thereby, the variation of the vaporization amount of heat medium that accompanies that of the treatment amount or temperature of solids is reduced so that a totally economical system can be obtained.

Filed: 1991-05-31
Abstract: PURPOSE:To assemble parts on a car body which requires many assembling manhours in reasonable manners, in a mixed production line or plural kinds of car bodies. CONSTITUTION:A car body Bs which requires the much assembly manhour among plural kinds of car bodies Bv, Br, and Bs which are mounted on transport hangers H1 and H2 and move on a main transport line L1 is confirmed by a machine kind confirming mechanism D3 and branched to a side separating transport line L3. After the car body Bs is transferred to a specific machine kind assembly line S2 from the transport hanger H2, and the parts specific for the car body Bs are assembled, the car body Bs is transferred to a mixed machine kind assembly line S3 by a transfer mechanism T2. Into the mixed machine kind assembly line S3, other machine kind car bodies Bv and Br are transferred from a main transport line L1, and the parts which are comnon for three kinds of car bodies Bv, Br, and Bs are assembled. Since the need of returning the car body Bs which is demounted from the transport hanger H2 to an original transport hanger H2 is obviated, the flow speed of the specific machine kind assembly line S2 for the car body Bs can be varied independently of the flow speed of the main transport line L1.

Title: Reader tape for magnetic tape
Inventor: SHINTANI YUUJI
IPC: G11B5/627
Filed: 1984-06-25
Abstract: PURPOSE:To eliminate defects such as disorder in winding when a magnetic tape is wound and generation of ruggedness by providing a transparent resinous layer on a shading electrically conductive resinous layer, which is formed on at least one surface of a transparent substrate film in a specified pattern and on the part on which the shading conductive resinous layer is not formed. CONSTITUTION:A transparent resinous layer 3 is formed on the part, on which a shading electrically conductive resinous layer 2 is not formed, in a reader tape 1. The transparent resinous layer 3 is formed, for example, by printing or coating the same resin as the resinous binder under for the shading conductive resinous layer 2 (namely, a transparent resin not contg. a shading pigment and a conductive substance) on the part of which the shading conductive resinous layer 2 is not formed. Although the thickness of the transparent resinous layer 3 is necessarily regulated so that the difference in thickness with the shading conductive resinous layer 2 is adjusted to <=2mum, the thickness is preferably mae identical to the thickness of the shading conductive resinous layer 2. When the difference in thickness between the shading conductive resinous layer 2 and the transparent resinous layer 3 exceeds 2mum, disorder in winding a magnetic tape and the transfer of ruggedness to the magnetic tape are unfavorably generated.

Title: Underwater pump
Inventor: MORI YUUJI
IPC: F04D13/10
Filed: 1978-10-26
Abstract: PURPOSE: To ensure that the suction of foreign matter falling from the upper portion of a driven well can be avoided by arranging a thin-walled cylinder around an underwater motor, forming the lower portion of an underwater pump with a suction port, and communicating the port with the interior of the cylinder.  
     CONSTITUTION: When foreign matter such as sand has fallen from the upper portion of a pipe 1 and collected on top of a casing 8, the operation of an underwater pump 3 causes the matter to fall through the gap between the pipe 1 and a thin- walled cylinder 6 and collect in the lower portion of the pipe 1, i.e. in the bottom portion of a driven well. However, the foreign matter cannot be sucked into the pump 3 because a suction port 5 is not opening into the gap. The suction port 5 of the pump 3 is so arranged that water is sucked in from a water intake port 10 formed in the bottom portion of the pump 3 sufficiently distant from the bottom of the  well through the gap 9 between the cylinder 6 and the outside peripheral wall of an  underwater motor 2. Thus, suction of foreign matter such as sand present in the  bottom portion can be avoided.

Title: Method for measuring retardation of compound sheet
Inventor: SAKAI KIYOKAZU
IPC: G01N21/23
Filed: 1993-05-08
Abstract: PURPOSE:To calculate the retardation of a sample by applying light from the side of the polarization film of a compound film, detecting transmission light via an analyzer, and then actually measuring the relationship between the detection output and the rotary angle position of the analyzer. CONSTITUTION:Light with a specific wavelength is selected via an optical fiber 2 and a film 3 from the emission light of a white light source 1 and then is guided onto a light axis A of a device. A polarizer stand 4 and an analyzer stand 6 are rotated in one piece by a motor 8 via a pulley and a belt on a common shaft. Normally, measurement is made by mounting the polarization plate on the stands 4 and 6 in parallel to the polarization direction but only the polarization plate of the stand 6 is used excluding that of the stand 4 for measuring a compound film. A sample S is set to a sample stand 5 with the polarization filter facing upward. While an analyzer 61 is being rotated, the azimuth angle of the analyzer 61 and then the intensity change of the transmission light of the sample S and the analyzer 61 is measured. Namely. a control device 9 rotates the motor 8 and at the same time detects the rotary angle of the analyzer 61 by counting the number of drive pulses, thus outputting it from a light reception element 7 for each certain angle and then outputting it.
