Title: Apparatus for producing metallic sheet
Inventor: MIHARA YUTAKA
IPC: B22F9/08
Filed: 1988-06-11
Abstract: PURPOSE:To provide the title apparatus for production which can produce a sheet of a hard-to-work material such as intermetallic compd. by constituting the apparatus in such a manner that a deposit is formed of the metal particles sprayed from a low-pressure plasma thermal spraying nozzle on a rotating type substrate in an inert gaseous atmosphere and is continuously supplied to constant-temp. working. CONSTITUTION:The molten metal particles are sprayed by a plasma jet from the thermal spraying nozzle 1 onto the substrate 2. The sprayed metal particles (m) are rapidly solidified and deposited on the substrate 2 to form the plate- shaped deposit D. The deposit D is then subjected to temp. regulation 3 for heating or cooling at need; thereafter, the deposit is drawn out of the substrate 2 and is rolled by a constant-temp. working machine 4. The sheet S emitted from the working machine 4 is subjected to a heat treatment intended to assure strength in a heat treatment furnace 5 and is then coiled by a coiler 6. Since all the above-mentioned operations are carried out in the inert gaseous atmosphere, the oxidation of the material is prevented.

Title: Magnetic sensor
Inventor: KOJIMA KAZUYOSHI
IPC: G01R33/07
Filed: 1987-06-09
Abstract: PURPOSE:To measure magnetic flux density with high sensitivity by amplifying the magnetic flux density detected by a 1st superconductive coil with large inductance and producing magnetic flux in a 2nd superconductive coil with small inductance. CONSTITUTION:The inductances L1 and L2 of the 1st and 2nd superconductive coils 1 and 2 which are connected by a superconductor are so set that L1>L2; and the coil 2 and a Hall element 3 are shielded by a magnetic shield 4. Then the coils 1 and 2 are put in a low-temperature state where they enter a superconductive state and the coil 1 is put in an external magnetic field to be measured. Its magnetic flux density is denoted as B. Here, magnetic flux which enters the loop formed of the coils 1 and 2 becomes 0 on the whole because of complete diamagnetism by the superconduction. When detection magnetic flux phi1 is interlinked with the coil 1 at a detection position, magnetic flux phi2 interlinked with the coil 1 in the opposite direction is interlinked with the coil 2 because of the magnetic shielding. When the magnetic flux density in the coil 2 is denoted as B2, B2approx.=(L1/L2)B. Here, L1>L2, so the density B2 in the coil 2 is larger than B. Namely, the magnetic flux is amplified and applied to the element 3.

Title: Molten carbonate fuel cell
Inventor: TSUKAGOSHI ICHIROU
IPC: H01M8/24
Filed: 1983-08-09
Abstract: PURPOSE:To improve reliability and maintainability in a long time of operation by installing a spring, comprising shape memory alloy, which expands and contracts in a stacked direction of a fuel cell stack. CONSTITUTION:Elasticity of a spring 20 is weak and fastening force applied to a fuel cell stack 11 is small at normal temperature. When the spring 20 reaches martensite transformation temperature by heat conducted from the cell through a fastening pressure and heat conducting rod 19, the spring expands to original shape, thereby fastening pressure is applied to the stack 11. When temperature is decreased, the spring 20 yields at martensite transformation temperature, and fastening force applied is released. When temperature of fuel cell stack is increased, proper fastening pressure is applied to absorb thickness change, and when temperature is decreased, fastening force is released. Therefore, breakage of electrolyte layer is prevented.

Title: Semiconductor device
Inventor: TAGAMI TOMOYUKI
IPC: G11C29/00
Filed: 1986-06-20
Abstract: PURPOSE:To shorten the substituting time without increasing the area of a chip by selecting a preliminary signal line circuit corresponding to a signal input to a signal line circuit in activated by opening a circuit opening element by a selector. CONSTITUTION:In order to replace bit lines BIT1,-BIT1 becoming improper with redundancy bit lines GIT1R,-BIT1R, a fuse FUSE is, for example, melted by a laser. Thus, a node 5 becomes 'H' by a transistor TP1, a node 6 becomes 'L', and the bit lines BIT1,-BIT1 are not permanently selected to be inactivated. Since the output of a gate NAND1 is 'L' and a transistor TP2 is turned ON, a node 12 is 'L' and a node 14 is 'H', thereby selecting redundancy bit lines BIT1R,-BIT1R. Thus, the increase in the area of a chip by a selector is suppressed, and the replacing time of the redundancy line can be shortened to reduce a chip cost.

Title: Pressure sensor
Inventor: SHOJI MASATO
IPC: G01L9/16
Filed: 1989-06-08
Abstract: PURPOSE:To make it possible to provide a sensor at an arbitrary position of a cylindrical pipe without a space by fixing amorphous magnetic alloy to the surface of the cylindrical pipe wherein fluid is transmitted. CONSTITUTION:When fluid flowing through the inside of a cylindrical pipe 1 is changed, the surface of the cylindrical pipe receives stress in the expanding or contracting direction. As a result, amorphous magnetic alloy 2 which is fixed to the surface of the cylindrical pipe 1 receives strain. The permeability of the alloy 2 is changed by an inverse magnetostriction effect from said strain. Then said change is detected by a pressure detecting coil 3 as the change in inductance. The pressure is obtained through a detecting circuit 6. In this way, the sensor can be attached to an arbitrary position without occupying an extra space.
