Title: Snow melting structure of railway crossing
Inventor: HARASHIMA JUNKO
IPC: E01C9/04
Filed: 1997-07-09
Abstract: PROBLEM TO BE SOLVED: To improve the performance by embedding a heat pipe in a crossing board provided between rails at the crossing, and interposing a damping rubber between the crossing board and a crossing foundation. SOLUTION: A damping rubber 4 is interposed between a crossing board 3 of a crossing A and a foundation 1 to prevent the vibration of a vehicle traveling on rails 2 from being propagated to the crossing board 3. Then, the crossing board 3 comprises a lower heat insulation plate 3-1 consisting of foamed urethane, etc., and an upper concrete plate 3-2. A pipe storage space S is provided in the plate 3-1 and a heat pipe M is embedded therein, and heat transfer particles 5 such as sand are filled in a clearance around the outer circumference of the pipe M.  When hot water is passed through a heat source pipe in the pipe M, the pipe M is heated by the fluid for heating medium in the pipe M, and the heat is transferred to the plates 3-1, 3-2 as the heat source having the far infrared wavelength through the particles 5 to melt the snow on the upper side or an end part of the crossing board 3. Functional degradation of the heat pipe caused by the vibration of a vehicle can be prevented, and snow can be efficiently melted.

Title: Semiconductor device
Inventor: MAYUZUMI SHIRO
IPC: H01L23/52
Filed: 1985-08-23
Abstract: PURPOSE:To reduce the displacement of aluminum wirings at the four corners of a semiconductor chip for a resin seal semiconductor device by forming the aluminum wirings on at least the insides of bonding pads at the four corners. CONSTITUTION:Al wirings 2 are shaped on the insides of bonding pad sections 3 at the four corner sections of an Si semiconductor chip 1, thus avoiding the formation of the Al wirings at the four corners. The pads 3 are subjected directly to the effect of stress sigma at that time, but the concentration of stress can be obstructed at a minimum while the pads are used as shields in the Al wirings 2. Bonding pad itself has a large area and is bonded with an SiO2 film 5 on a substrate, and adhesive strength thereof is extremely large, thus preventing displacement by stress of bonding pad itself. Since the first layer wiring is displaced by stress and the second wiring returns to an original position when stress is removed even when the second wiring is displaced by stress, it is preferable that the wiring is lead out of the bonding pad in the second layer wiring.

Abstract: PURPOSE:To reduce wirings on a substrate and to withstand electric and magnetic noises by converting light into current, injecting the current into a superconductor, and switching an SIS element by utilizing the current-voltage characteristic of the superconductor. CONSTITUTION:An insulating film 9 is formed on only the half of a non-doped Si wafer substrate 8. A lower electrode 10, an insulating layer 11 and an upper electrode 12 are further laminated on the film 9, and an SIS element 13 is formed. The element 13 is a signal detecting part using a Josephson junction. The electrodes 10 and 12 are constituted of superconductors. At this time, the current which is generated in a light receiving part is injected into the superconductors. Thus the element 13 is switched by utilizing the voltage-current characteristic of the superconductor. When the material of the light receiving part is appropriately selected, the light in a required wavelength region can be detected. When this element is operated as a memory element, light signals are used. Thus the wirings of the substrate 8 are reduced. Therefore, the element which is highly resistant to electric and magnetic noises is obtained.

Title: Coated electrode for welding of cr-mo steel
Inventor: HATSUTORI NAOJI
IPC: B23K35/365
Filed: 1981-11-18
Abstract: PURPOSE:To improve the strength, toughness and weldability of a coated electrode for Cr-Mo steel by coating a coating material which contains specified weight ratios of metallic carbonates, metallic fluorides and metallic oxides and is limited of component compsn. at specific weight ratios on an electrode which is limited of component compsn. CONSTITUTION:A coating material contg., by weight, 30-60% metallic carbonates, 10-30% metallic fluorides and 4-20% metallic oxides is coated on the outside circumference of a core wire in such a way that the ratio of the coating material to the total weight of the electrode attains 23-33%, and 0.06-0.12% C, 1.0-1.8% silicon, 0.4-1.0% Mn, 6.5-8.7% Cr, and 1.5-2.0% Mo based on the total weight of the electrode are contained in the covering material and/or the core wire. The reasons for limiting the component compsns. in the covering material and core materials lie in that if the carbon is too much weldability degrades. If the silicon is too little, blowhole are produced in deposited metal and if the silicon is too much, toughness degrades. If the Mn is too much, as- welded hardness is too high. If the Mo is too little, high temp. hardness is not obtained and if the same is too much, the deposition of a ferrite phase increases.
