Abstract: PURPOSE:To develop the title highly safe gaseous H2 generator without mixing gaseous H2 and gaseous O2 by dividing the inside of a high-pressure vessel into two sections by-a gas-impermeable partition wall, and providing an electrolytic cell consisting of a hydrogen ion-permeable membrane having a catalytic electrode on both sides at the lower part of the partition wall at the time of producing gaseous hydrogen by water electrolysis. CONSTITUTION:The electrolytic cell 2 consisting of a hydrogen ionpermeable membrane 6 having the catalytic electrodes 4 and 5 on both sides is arranged at the lower part of the high-pressure vessel 1 as the device for generating gaseous H2 and gaseous O2 by water electrolysis, and the upper part is divided by the gas-impermeable partition wall 3 into a hydrogen tank 9a and an oxygen tank 9b. Water is supplied into the high-pressure vessel 1 by a pump 12 from a water tank 11, and a DC voltage is impressed on both catalytic electrodes 4 and 5 of the electrolytic cell 2 to electrolyze water. The generated gaseous H2 and gaseous O2 are respectively stored in the tanks 9a and 9b separated by the partition wall 3, and taken out through pressure reducing valves 10. Since the gaseous H2 and gaseous O2 are not leaked and mixed, a dangerous explosive gas is not formed, and gaseous H2 and O2 are stably and continuously produced.

Title: Permanent magnet and its manufacture
Inventor: NAGAI TAKESHI
IPC: H01F41/02
Filed: 1991-03-15
Abstract: PURPOSE:To suppress the concentration of surface magnetic flux densities to the end sections of a permanent magnet by forming a ferromagnetic coating film on the principal surface of the magnet body in such a way that the film at the end sections is made thicker than at the central part. CONSTITUTION:In order to rectify the uneven surface magnetic flux density of a magnet blank, the film thickness of a ferromagnetic coating film 2 formed on a permanent magnet body 1 at the end sections 3 on the principal surface of the body is, preferably, made 1.5 to 10 times as thick as that at the central part 4. When the film thickness of the film 2 at the end sections 3 is 1.5-10 times thicker than that at the central part 4, the rise of the permanent magnet at the end sections 3 can be suppressed to a height (y), since the surface magnetic flux density of the permanent magnet body 1 becomes smaller as the film thickness of the film 2 becomes thinner. When the film thickness of the film 2 is controlled in such way, the (x-y)/x becomes about 5-30% and the concentration of magnetic fluxes to the end sections can be suppressed by 5-30%. As a result, the area of the principal surface having a uniform magnetic flux density is also increased.

Filed: 1995-03-31
Abstract: PURPOSE: To provide the gas piping leak inspecting device with which the presence/absence of minute leak at large capacity gas piping is prevented from being erroneously discriminated as the presence of fine leak by supplied pressure fluctuation or the like. CONSTITUTION: The flow rate of gas is measured by a flow rate detecting means 15 provided at a gas bypass path 11a parallel with gas piping 11 cut by a cutting means 13. Based on this flow rate of gas, a fine leak detecting means 27a-1 detects the presence/absence of fine leak. Based on the upstream side gas pressure detected by a gas pressure detecting means 14a, a pressure fluctuation detecting means 27a-2 detects pressure fluctuation and corresponding to this result, the flow rate detecting means stops measuring the flow rate of gas. Minimum value storage means 27c41 -27c49 collect the minimum value of gas flow rate measured on one day for several days as many as periodical life patterns at least and store them. Corresponding to the change pattern of this minimum value, the fine leak detecting means detects the presence/absence of fine leak.
