Title: Superconducting rectifier
Inventor: NOGUCHI TAKU
IPC: H02M7/00
Filed: 1986-07-23
Abstract: PURPOSE:To obtain a superconducting rectifier capable of operating at a low temperature such as liquid helium temperature by using at least one control line magnetically connected to a Josephson device, and applying a d.c. current and an a.c. input signal to the control line. CONSTITUTION:When a constant d.c. current IB flows from a terminal 12 to a Josephson device 10, a voltage  V appears across the Josephson device 10. Now suppose that a control current IC1 flows through a control line 1 to magnetically bias the Josephson device 10 (the bias current IB is kept to flow through the Josephson device 10), and that an a.c. current is delivered to a control line 2. Both currents are mathematically added together to apply a magnetic field to the Josephson device 10. After d.c. components are removed by a blocking capacitor 5, the output voltage is further smoothed by a smoothing circuit 11 and a d.c. voltage is obtained. With this, a rectifier which is capable of operating at a very low temperature and has a remarkably small thermal noise effect and a high resolution can be obtained.

Title: Hardening method for mushroom valve stem end
Inventor: KOYAMA TAKAO
IPC: F01L3/02
Filed: 1986-07-23
Abstract: PURPOSE:To accomplish the inexpensive hardening of a valve stem end without any decrease in a product performance by providing a hole at a mushroom the stem end of which is made of a non-quenched material, requiring an abrasion resistance and pressing an abrasion resistant member formed protrusively into the hole. CONSTITUTION:A mushroom valve which is made of a non-quenched material and requiring an abrasion resistance is provided with a carburized quenched medium or other abrasion resistant member 3 at the valve stem end surface. In this case, a press fit protruding portion 4 is formed at the center of the abrasion resistant member 3. On the other hand, a press fit hole 5 in which the press fit protruding portion 4 is to be pressed is provided at the stem end surface of the non-quenched medium 1. Then respective contact faces of the abrasion resistant member 3 and the non- quenched medium 1 are made to stick together by pressing the press fit protruding portion 4 into the press fit hole 5 under an ordinary temperature, thereby the abrasion resistance of the stem end surface of the non-quenched medium 1 is made to improve by providing the abrasion resistant member 3. This enables the simple and inexpensive hardening for the valve stem end surface of the mushroom valve without a decrease in a product performance.

Abstract: PROBLEM TO BE SOLVED: To compactly fix up a valve main body and a cutoff device, and reduce required costs and times to a great extent by integrally combining a lock releasing device releasing the lock of the emergency cutoff valve which automatically actuates a valve closing action in case of emergency such as severe earthquakes and the like. SOLUTION: When vibrational acceleration as specified is applied thereto because earthquakes take place, a pendulum 14 is rocked so as to allow an action plate 15c to be pushed up by a brim 14a, a lock releasing member 15 is revolved by the action of a spring 24, and the locking condition of a pin 15a with a recessed part 12b is thereby released. By this constitution, a locking member 12 is revolved so as to allow a locking condition with a locking step part 11 to be released, a valve shaft is thereby revolved by an arm connected with a revolving member 10 by way of a link mechanism so as to allow a valve body to be closed, and a fluid pipe line is thereby urgently cut off. In this case, a valve body is compactly fixed up with a cutoff device by providing a lock releasing device 16 integrally with the valve box of an emergency cut-off valve.  Besides, a power supply can be eliminated, and costs and times can thereby be reduced, which are required for the installation of the emergency cutoff valve, the cutoff device and the like.

IPC: C23C2/00
Filed: 1994-07-25
Abstract: PURPOSE:To surely hold a molten metal bath in a hollow pot by making the sealing members in the parts facing metallic sheet surfaces slidable in the thickness direction of the metallic sheet. CONSTITUTION:The bottom of the hollow pot 2 in which molten zinc 5 is put is divided by a steel sheet passing plane to form long-side sliding members 3, by which the sealing members facing the steel sheet surfaces are formed. The long-side sliding members 3 are made movable by a forward and backward driving device in correspondence to a fluctuation in the steel sheet surfaces. As a result, the distance between the steel sheet and the side walls of the aperture is kept constant even if the sheet thickness changes. The sealing members are made slidable in the transverse direction of the metallic sheet. The position and size of the aperture are made further continuously changeable in such a manner. The improvement in the yield of the steel sheet and the reduction of the cost required for maintenance of the device are thus attained.

Abstract: PROBLEM TO BE SOLVED: To provide a fuel cell and its fastening method which can be embodied while the configuration remains simple and can reduce the ion conduction resistance of a solid highpolymer electrolytic film itself and also the ion conduction resistance and contact resistance between the electrolytic film and an electrode plate. SOLUTION: A first separator 16 made of a dense substance is fitted in a hole 24 furnished in a second separator 18 made of dense substance, and a chamber 25 is partitioned by the first and second separators 16, 18 and filled with a filler 83. The first separator 16 is pressed toward a solid highpolymer electrolytic film 60 by the pressure of water introduced to the chamber 25 and is moistened with water and swollen. At the same time, the filler 83 in the chamber 25 will moisten and swell. This moistening/swelling effect increases the pressing force for cells of the fuel cell and strengthens the tightening force for the stack of the cells.  Through moistening and swelling, the internal resistance of the electrolytic film 60 reduces, and also the ion conduction resistance between the film 60 and the first separator 16 is reduced along with the reduction of the contact resistance for electron conduction.

Title: Grinding
Inventor: KAWADA KENJI
IPC: B24B31/112
Filed: 1983-09-21
Abstract: PURPOSE:To permit fine grinding even if a ground surface is not uneven, by allowing a magnetic field to act onto the magnetic fluid containing several kinds of non-magnetic grinding grains having different values of specific gravity and grinding the surface of the ground body by the grinding layers of non-magnetic grinding grains which are discriminated for each species. CONSTITUTION:When the magnetic field due to a magnet 3 is allowed to act onto the magnetic fluid 2 containing minute non-magnetic grinding grains 11 and 12, the downward gravity Fg and an upward magnetic floating force Fl act onto the non-magnetic grinding grains. Under the condition where F1<F2<0 or F2< F1<0, the non-magnetic grinding grains 11 having a specific gravity of rho1 and the grinding grains 12 having a specific gravity of rho2 form grinding layers 41 and 42 which can not be distinctly discriminated in the magnetic fluid 2, and when the both or either of a grounded body 5 or the grinding grains is transported under friction state, the surface of the ground body 5 is ground by the floating-up force of the non-magnetic grinding grains 11 or 12. Therefore, continuous grinding in the state where the ground surface has any different shape is permitted.
