Title: Fault processing system for arithmetic processor
Inventor: HASHIGUCHI TATSURO
IPC: G06F11/20
Filed: 1989-09-07
Abstract: PURPOSE:To prevent system operation from being stopped by closing an exclusive arithmetic unit when a fault occurs in the unit, and retrying an instruction under the closed state of the failed unit. CONSTITUTION:A fault processor 1 executes recovery processing such as the collection of fault information and the retrial of an instruction at the time of generating a fault in an arithmetic processor 2 and a microprogram control part 3 controls a basic arithmetic processing part 4 and plural exclusive arithmetic processing parts 5-1, 5-2 and executes software instructions. If a fault is generated in the processing part 5-1, the processor 1 closes the processing part 5-1 and retries the instruction. Since the fault is removed, the instruction retrial surely succeeds by an alternative microprogram routine. Consequently, the system can be prevented from stopping its operation.

Abstract: PURPOSE: To reduce a gas generation amount in a bubble generating stage of the charging process of a lead storage battery, without elongating its charging time, by making the charging voltage - current characteristic curve every its cell intersect a bubble generating level at 0.5 I when I is its nominal load current, and by making the gradient of the characteristic curve about -0.5V/I--0.1V/I. CONSTITUTION: In a charging process according to the present invention, the charging current of a cell is maintained in a fixed value I5 until a cell voltage Uc reaches the bubble generating level of 2.4V to follow an I characteristic 1. Thereafter, the charging current follows a U-characteristic 2 until it lowers to 0.5 I5 to intersect thereafter a voltage axis of ordinate at 2.5V per cell, following a W-characteristic 3. Thereby, a gas generation amount in the charging process of a lead storage battery can be reduced without increasing its charging time beyond an allowable range.

IPC: G11B5/588
Filed: 1983-12-12
Abstract: PURPOSE:To eliminate the stored error voltage by subtracting the error voltage equivalent to two tracks when the stored error voltage exceeds a fixed threshold level. CONSTITUTION:The loci of magnetization are shown by A1, B1..., and a state (c) shows that the actual tape speed is lower than the expected speed. The voltage applied to a bimorph 17 is set at O in the 1st scan, and the voltage equivalent to 0.5TP (track pitch) is applied to the bimorph 17 in the 2nd scan to perform a scan on a track A2. The errors are gradually stored, and the bimorph applied voltage corresponding to an arrow head is stored to a memory circuit. When a head 18 reaches a position 39 with application of the 2TP threshold voltage, the value obtained by subtracting the 2TP potential from the bimorph applied voltage is applied to the bimorph 17 in the next scan mode 40 to set the head at a position 41. Therefore A5 is scanned again after scanning A1-A5, and then A6 is scanned.
