Title: Multiple function optical fiber
Inventor: SHIODA TAKAO
IPC: G02B6/02
Filed: 1985-02-12
Abstract: PURPOSE:To miniaturize the device by unifying two or three optical fibers having different functions to one optical fiber. CONSTITUTION:Light power sent by a glass part 20 for power transmission is converted to electric power in a subscriber's terminal by, for instance, a solar battery etc., and used for power source of the receiving device of the glass part 10 of an optical fiber for information transmission. A glass part 30 for a sensor is used to detect abnormality of a light transmitting path. When there is bending or breaking due to defective laying work of a multiple function optical fiber 70, occurrence of it and the position can be detected by a detector 93. Temperature can also be detected utilizing the fat that the amount of scat tered light changes with change of temperature. Thus, as glass parts of plural optical fibers having different functions are drawn included in a common glass jacket 40, the equipment in a subscriber side can be made small.

Title: Surface-treated steel sheet for cationic electrodeposition coating
Inventor: TAKEUCHI TAKESHI
IPC: C25D13/20
Filed: 1987-02-05
Abstract: PURPOSE:To prevent the generation of pinhole defects in an electrodeposited film by plating a Zn-based metal having excellent corrosion resistance on the surface of a steel sheet, and then electroplating Mg-contg. Fe on the Zn-based metal plated layer, and electrodepositing thereon. CONSTITUTION:The Zn-based metal such as Zn, a Zn-Fe alloy, and a Zn-Ni alloy is plated by a molten-metal plating method on the cold-rolled steel sheet as the outside plate for an automobile. An Fe electroplated layer contg. 0.1-2.0wt.% Mg is formed on the Zn-based metal plated layer at >=1g/m<2> by using an Fe plating soln. contg. MgO. The surface is subsequently phosphate, and then the electrodeposited film of a cationic electrodeposition paint is formed thereon. The phosphate film forms a dense phosphofilament by the presence of the Mg-contg. Fe plating layer, and the generation of the pinhole defects due to the gaseous H2 generated from a material to be coated as the cathode in electrodeposition can be prevented.

Title: Resin composition for antifouling paint
Inventor: WATADA YUKIO
IPC: C09D5/16
Filed: 1988-02-04
Abstract: PURPOSE:To obtain the title composition which is nontoxic, can retain its effect of preventing the deposition of life and has easy removability, by mixing a specified room temperature-curable silicone rubber with a specified amount of a silicone-containing vinyl resin. CONSTITUTION:A room temperature-curable silicone rubber (A) based on a diorganopolysiloxane having terminals blocked with hydroxyl groups and a silane of formula I (wherein R<1> is methyl, vinyl or phenyl, and X is methoxy, ethoxy, methyl ethyl ketoxime or the like) or its partial hydrolyzate is mixed with a homopolymer of a silicone-containing acrylic monomer of formula II (wherein R<2> is H or methyl, R<3> is a 1-6C bivalent hydrocarbon group, and n is 0 or 1-200) or a copolymer thereof with a copolymerizable vinyl monomer in a weight ratio of A to B of 100:3-80 in terms of solid content. Although the use of only resin A known as a nontoxic vehicle for antifouling paint cannot bring about a long-term effect of preventing the deposition of life, the combined use with resin B can bring about a remarkably improved effect of preventing the deposition of life, presumably because a discontinuous phase is formed by the addition of resin B.

Title: Abnormality detecting apparatus for grain-moisture measuring device
Inventor: UEJI HITOSHI
IPC: G01N27/04
Filed: 1989-02-03
Abstract: PURPOSE:To facilitate the judgment for the presence or absence of abnormality in a grain-moisture measuring device and to make it possible to make the cost of an abnormality detecting apparatus low by providing a checker which conducts both detecting rolls at one side of a pair of the detecting rolls. CONSTITUTION:When a grain-moisture measuring device detects abnormal grain moisture or does not detect the moisture in the grain during drying work, whether abnormality occurs in said grain-moisture measuring device or not is judged with an abnormality detecting apparatus. At the time of judgment, a checker 2 is mounted on one detecting roll 1 of a pair of detecting rolls so that both detecting rolls are conducted. When the grain-moisture measuring device is started, both detecting rolls become conductive at a specified time interval. The resistance value is detected by the same way when the grain is compressed and crushed. When the detected resistance value is equal to the specified value, it is judged that the grain-moisture measuring device is normal with the checker 2. When the detected resistance value is out of the specified value, it is judged by the checker 2 that the abnormal state occurs in this grain-moisture measuring device.

Filed: 1982-02-18
Abstract: PURPOSE:To simplify a demagnetizing apparatus by making the magnetic resistance of a mask body smaller than that of a frame so as to permit the demagnetizing action to be developed effectively. CONSTITUTION:The magnetic resistance of a mask body 4b having an aperture 4a is set smaller than that of a frame 4c which supports the peripheral edge part of the mask body 4b. The mask body 4b and the frame 4c are connected to each other through welding. As the magnetic resistance of the mask body 4b is thus set smaller than that of the frame 4c, it becomes difficult for the magnetic flux from a demagnetizing coil to pass through the frame 4c, said magnetic fluxes are concentrated onto the mask body 4b, and the demagnetization effect of the mask body 4b can be improved.

Title: Semiconductor laser device

IPC: H01S5/00
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To restrain generation of heat cycle, in a semiconductor laser device in which a semiconductor laser chip and a heat sink are integrated. SOLUTION: When the output of a semiconductor laser is stopped, or in the case of standby, or when pulse driving is turned off, heat equal to the amount of heat generated when a semiconductor laser chip 31 is operated is generated by a heat generating source 36. In this case, the difference of temperatures of the heat sink 32 and the semiconductor chip 31 is made equal to or nearly equal to the temperature difference when the semiconductor laser power is outputted or pulse driving is turned on. As a result, the number of times of heat cycle caused by fluctuation of temperature diference between the semiconductor laser chip 31 and the heat sink 32 is reduced as compared with the practical number of times of ON and OFF of the semiconductor laser.
