Title: Membrane separator
Inventor: TANIYAMA TSUKASA
IPC: B01D63/02
Filed: 1981-07-06
Abstract: PURPOSE:To prevent the breakdown of porous glass owing to differences in the coeffts. of thermal expansion by constituting a partition wall which partitions a fluid chamber communicating with the inner side of hollow porous glass fibers and a fluid chamber communicating with the outer side of said fibers of an elastic material. CONSTITUTION:When raw material liquid is introduced through the opening 16 of an end plate 3 into a porous tube 7, the fluid enters hollow fibers 4, flows through a fluid chamber 21 and is discharged through an opening 17. During the flow of the fluid through the hollow fiber bundle 4, part of the fluid permeates through the outside circumferential surface side of the fibers to the hollow part side, passes through the flow passages in the hollow part, penetrates through a partition wall 5 and enters a fluid chamber 20 communicating with the inner side of the hollow fibers. This fluid is removed through the opening 18 of an end plate 2. The material of the partition wall is natural rubber, synthetic rubber, rubber-like plastics, etc. that have superior heat resistance and withstand quick heating and cooling when the hollow fiber bundle is sealed. If a material of a small modulus of elasticity is used for the partition wall material, the forces acting upon the fibers are small and the failure thereof is prevented.

Title: Gas leak detector
Inventor: NAKAMURA MUTSUMI
IPC: F17D1/04
Filed: 1994-05-20
Abstract: PURPOSE:To provide a gas leak detector aiming at miniaturization, cost reduction and light weight. CONSTITUTION:An automatic opening/closing valve means 2 provided on the way of a gas supplying passage automatically opens and closes a valve body 24 according to the presence or absence of gas consumption on the downstream side. A pressure detecting means 3 detects pressure on the downstream side of the automatic opening/closing valve means, and the detected pressure is compared with the specific value previously determined by a comparison means of a judging means 4. The judging means judges that there are possibilities that gas leakage is generated when the times that the detected pressure becomes the specific value or more are less than the specific times for the specific period counted by a counting means. A diaphragm 32 is displaced by differential pressure between both gas pressures after receiving gas pressures on the upstream side and the downstream side of the automatic opening/closing valve means, and the displacement is transmitted to the valve body by a connecting member 47b of a valve body driving means 47 for connecting the diaphragm 32 to the valve body.

Title: Manufacture of aluminum etching foil for electrolytic condenser
Inventor: KOIKE ATSUSHI
IPC: H01G9/04
Filed: 1989-04-26
Abstract: PURPOSE:To prevent the hydration at a coil end from occurring thereby enabling an etching foil in even characteristics to be manufactured extending over the whole width direction by a method wherein, before winding around the title aluminum etching foil taking a coil shape, the foil is passed through atmospheric gas or an inert gas dried up at specific temperature so as to dehydrate a natural hydrate film formed on the surface of the foil. CONSTITUTION:When an aluminum foil dielectric condenser is etched and then wound around taking a coil shape to be heat-treated in an inert gas atmosphere, the aluminum foil, before it is wound around taking the coil shape, is passed through atmospheric gas or the inert gas dried up at 200-450 deg.C to dehydrate a natural hydrate film formed on the said foil. For example, a previously etched aluminum etching foil is passed through the atmospheric gas dried up at 200 deg.C and then the etching foil is wound around taking the foil shape to be heat- treated in Ar gas atmosphere at 500 deg.C for two hours. Through these procedures, the hydration at the coil end can be prevented from occurring, thereby enabling the etching foil in even characteristics to be manufactured extending over the whole width direction.

Abstract: PURPOSE:To grasp quickly and accurately a position of a magnetic head to a reference position by detecting contents of recording of a master tape by means of a magnetic head of a magnetic recording device and detecting a position of the magnetic head to the reference position from a timewise change of the detected output within a prescribed period. CONSTITUTION:The master tape is loaded to the magnetic recording device. Then the magnetic recording device is operated and a signal recorded on the 1st and 2nd signal tracks 35, 36 of the master tape is detected by a magnetic head 18. The timewise change of the signal level depends on the relation of position of the magnetic head 18 to signal tracks 35, 36, i.e., the relation of position among the reference track 32, side tracks 33, 34 and the magnetic head 18. Thus, the relative position of the magnetic head 18 to the tracks 32, 33 and 34 at that time is confirmed by observing the form of a reproducing signal displayed on a cathode ray tube.
