Title: Deciding system for memory parity error
Inventor: KUMAKURA HIROSHI
IPC: G06F12/16
Filed: 1988-04-15
Abstract: PURPOSE:To improve the working efficiency in a debugging mode by using a deciding part to decide whether a parity error is produced in a using area or an unused area. CONSTITUTION:A parity check part 2 detects the parity errors with collation of the parity bits obtained in the write and read states of a memory 1. A deciding part 3 is connected to an address bus 4 and decides whether a parity error is produced in a using area or an unused area based on the read address information on an address bus 4 at reception of a parity error detecting signal from the part 2. Based on the result of said decision, the part 3 outputs a hardware error signal or a program error signal to the outside.

Abstract: PURPOSE:To contrive making the total accommodating capacity of a smoothing reactor into a compact size in such a way that a current smoothing reactor is installed on a rectifying arm through which battery charging current in a bridge circuit is flowed, in an electric railway using a direct current feeding system. CONSTITUTION:If thyristors 7a, 7d are turned on when charging a battery 6, charging current Ic flows through a feeder line 2 - a disconnector 9b - HSCB 9a - a battery 6- a reactor 10 - a thyristor 7a - a rectifier 8 - a thyristor 7d - a disconnector 9c - rails 3. On another hand, when discharging, if thyristors 7b, 7c are turned on, discharging current Ip flows through the rails 3 - the disconnector 9c - the thyristor 7c - the rectifier 8 - the thyristor 7b - the battery 6 - the HSCB 9a - the disconnector 9b - the feeder line 2. Thus, since current Ic only flows to the reactor 10, its capacity is enough with small capacity corresponding to the current Ic, and it is unnecessary to have such a large inductance as to be required for the current Ip.
