Abstract: PURPOSE:To improve the performance of an on-line system by outputting the content of a journal buffer to a spare external memory device when a fault is generated. CONSTITUTION:Records (1-10) as history information are buffered in the journal buffer 31, and a CPU issues the output request of the records (1-5), and the records (1-5) are buffered in the buffer 51 of a magnetic tape device, however, figure shows a case where the records (1-3) are outputted to the tape 52 actually. In such a case, a pointer PB indicates the record 5, and a pointer PR indicates the record 3. The CPU issues the output request of the records to the record 5 in the journal buffer 31, and since the records (1-3) are already outputted to the tape 52, the storage areas of the records (1-3) in the buffer 31 can be used again, and since no output request of the records (6-10) is issued, the CPU issues the output request to the tape device successively. In such a way, it is possible to improve the performance of the on-line system.

IPC: B23K1/20
Filed: 1991-03-29
Abstract: PURPOSE:To enable a glass layer to be easily removed at a low cost by a method wherein a thick film conductor provided onto a support is cleaned with organic acid solution to remove the glass layer induced on the surface of the thick film conductor. CONSTITUTION:A thick film conductor provided onto a support is cleaned with organic solution to remove a glass layer induced on the surface of the thick film conductor. Material whose main component is Ag, Ag-Pd, Cu or the like can be used as the material of the thick film conductor concerned. The water solution of carboxylic acid or hydroxy acid such as citric acid, ammonium citrate, lactic acid, oleic acid, stearic acid or the like can be employed as the organic acid concerned. For instance, a Cu thick film conductor is dipped into the water solution of 0.2-4.0% by weight of citric acid or ammonium citrate for 5-120 seconds, whereby a thin glass layer generated on the surface of the Cu thick film conductor is removed. By this setup, a glass layer can be easily removed from a thick film conductor at a low cost before the thick film conductor is subjected to a soldering process or an electroplating process.

IPC: F16H9/12
Filed: 1995-02-28
Abstract: PURPOSE: To lessen frictional resistance at sliding so as to shift a mobile pulley with small thrust, by uniting resin tips for sliding with the crests at the tips of a plurality of salient pillars projected at intervals at a torque cam thereby forming cam faces. CONSTITUTION: Three salient pillars 5d are projected each integrally at specified intervals at a base 5b, and a cam face 5a is made in crest shape at the tip of each salient pillar 5d. A resin tip for sliding the crest at the tip of each salient pillar 5d is united, and the cam face 5a is made of resin tip for sliding. Therefore, it follows that the cam face 5a at the tip of each salient pillar 5d abuts and slides on the gently slanting cam face 6a of the hub 6 fixed to an output shaft, and for the cam face, the frictional coefficient by resin tip for sliding is small, and a mobile pulley can be shifted to the side of a fixed pulley, in condition that the sliding resistance of the torque cam is small.

Title: Method and apparatus for testing switch gear
Inventor: MATSUDA MATSUO
IPC: G01R31/333
Filed: 1985-03-30
Abstract: PURPOSE:To verify the interrupting performance allowed for a high frequency rush current based on the restored voltage to be applied to a sample after the interruption of the current, by making the high frequency rush current overlap a combined current of a lagging power-factor current and a leading power-factor current flowing during the closing of the sample. CONSTITUTION:After a capacitor (C) 20 is charged with a power source 23 and a rectifier 22, a charge current of the C20 is applied to a sample 4 via reactor 21 when a switch gear 24 is closed. Under such a condition, upon the closing of the sample 4, a high frequency rush current starts to flow from the C20 via the unit 24 and the reactor 21. At the same time, when a switch gear 3 is closed, a lagging power-factor current flows to the sample 4 from a power source 1 via the reactor 2 and the unit 3 while a leading power-factor current flows to the sample from a power source 5 via the unit 6 and a unit 6 and C7 when the switch gear 6 is closed. With such an arrangement, the interrupting current flowing to the sample 4 will be a combined current of the lagging and leading power-factor currents and the high frequency rush current overlapped thereby. Here, when the unit 3 and the sample 4 are interrupted, after the interruption of the unit 24, a restored voltage is applied to the sample 4 from the power source 5. Thus, interrupting performance test can be done by verifying the generation of refiring with respect to the voltage.
