Title: Apparatus and method for detecting leakage
Inventor: KURAUSU HANDOKE
IPC: G01L21/00
Filed: 1990-11-30
Abstract: PURPOSE: To detect leakage from an object to be tested in a testing container by using a pump device incorporating a mass spectrometer, a primary vacuum pump, and a spiro-molecular pump and making the atoms of a rare gas to flow toward the mass spectrometer through the pump device in the direction opposite to the pumping direction. CONSTITUTION: A testing container 2 is terminated with a purge gas duct through a valve 3 and has a purge carrier gas outlet 5 provided with a control valve 4. The container 2 is closed with a lid 6 after an object 1 to be tested is put in the container 2. In addition, the container 2 is connected to an accumulator 8 through a shut-off valve 7. The chamber 8 has a volume which is distinctly larger than the volume of the space around the object 1 in container 2. The chamber 8 is connected to the outlet 10 of a spiro-molecular pump 11 and, at the same time, to the suction side of a primary vacuum pump 13 through a shut-off valve 12. Since a mass spectrometer 14 is positioned on the suction side of the pump 11, helium atoms sent from the object 1 approach the spectrometer 14 in the direction opposite to the normal pumping direction of the pump 11.

Title: Overcurrent protecting ptc thermistor
Inventor: INOUE KIYOSHI
IPC: H01C7/02
Filed: 1990-11-30
Abstract: PURPOSE:To obtain a PTC thermistor device which can meet the requirements of a low specific resistivity and a high breakdown strength by a method wherein lead wires are fixed to ohmic silver electrodes with conductive paste. CONSTITUTION:Lead wires 4 are fixed to ohmic silver electrodes 2 with conductive paste 3. For instance, the ohmic silver electrodes 2 having diameters of 20mmphi are printed and baked on both the surfaces of a barium titanate system porcelain having a thickness of 2.2mm and a diameter of 22mmphi to form a PTC thermistor device 1. The copper wires 4 having diameters of 0.15mmphi are attached to the device 1 as shown in the figure and suitable quantities of silver paste 3 are put on the electrodes 2 and the wires 4 as the conductive paste and exposed to a temperature of 150 deg.C for 45 minutes to cure. With this constitution, as plating and soldering are not necessary, the deterioration of a breakdown voltage which is caused by the penetration of Cl ions in plating solution and flux can be avoided and, further, a solder melting voltage can be eliminated, so that high characteristics can be obtained.

IPC: C02F1/20
Filed: 1992-12-17
Abstract: PURPOSE:To recover and reuse ammonia as ammonia water by means of a system of a simple structure without gnerating odor pollution by counting ammonium ion into ammonia and then making the ammonia permeate together with water vapor through membrane thus removing ammonium ions. CONSTITUTION:Alkali is added to an ammonium ion-containing liquid from a storage tank 1, and then the liquid is agitated by a mixer 3, to adjust pH, and fed into a deaeration membrane module 5.

Title: Recording medium raid library device
Inventor: MATSUMOTO TADASHI
IPC: G06F11/00
Filed: 1998-11-30
Abstract: PROBLEM TO BE SOLVED: To provide a recording medium RAID library device capable of continuously performing preprocessing even if the space area of an 'alternate sector' of plural recording media in which data write processing is simultaneously performed is used up. SOLUTION: A dedicated management area where data can be saved separately from alternate sectors is provided in every plural recording media being objects of data striping processing. A controlling means can write data in the management area after using all of the alternate sectors and read data written in the management area. By doing this, it is possible to increase the data area capacity of the alternate sectors in an auxiliary manner and to successively perform data write processing even if the capacity of the alternate sectors is overed. Because the capacity of the management area can optionally be decided by a user side and the capacity can be easily grasped, it is possible to confirm a space area before the data write processing.
