Title: File over preventing system
Inventor: NAGAO JUNICHIRO
IPC: G06F12/00
Filed: 1990-12-27
Abstract: PURPOSE:To prevent overflow by analyzing label information of files to calculate the use rates of files and extracting in advance and extending the file which is likely to overflow. CONSTITUTION:An input means 2 takes file label information from an input device 1 as the input and outputs it to an analyzing means 3. This means 3 calculates the use rates of files in accordance with inputted file label information; and if there is a file having >=90% use rate, this file is extracted. A discriminating means 4 discriminates whether the extracted file can be extended or not. That is, when the file is extracted, it is discriminated whether the same magnetic disk has two-fold or more idle area of the extracted file or not; and if it has no idle area, it is discriminated whether another magnetic disk has this idle area or not. An extending means 5 calculates the extension capacity of the extracted file to extend the file and stores it in the idle area.

Title: Power distribution system operating device
Inventor: HASEGAWA OSAMU
IPC: H02J13/00
Filed: 1990-12-27
Abstract: PURPOSE:To improve reliability and safety in the operation of a power distribution system by simulating a system after an operation by a closing command based on the state of a power distribution system, determining the presence or absence of an overload, and outputting an alarm signal if the presence of the overload is determined. CONSTITUTION:An overload discriminator 11 which receives a close command determines whether an overload is generated by the closure of an interlocking point switch 4c or not. That is, it is understood that a zone 5g is interrupted at present and with a zone 5g as a power source zone a charging state occurs by closing the switch 4c. When the power source side zone of the zone 5f is sequentially traced, it is known that a feeder for supplying power to the zone 5g is a feeder 2a. On the other hand, when a current I' flowing to the feeder 2a after the switch 4c is closed exceeds the allowable current of the feeder 2a, the presence of the overload is determined, and the discriminator 11 transmits an overload generation alarm signal to an operation desk 10.

Abstract: A windscreen-wiper system in which a wiper blade is rotatably mounted on a telescopically extendable part of the wiper arm and can be moved, lying substantially flat, laterally over the vehicle windscreen. The drive producing the pivoting motion of the wiper arm is transmitted to the wiper arm via two cable lines, the first of which causes the wiper blade to rotate when its two lengths of cable move relative to each other. The second cable line is used to alter the length of the wiper arm. It consists of paying-out a cable which passes over a first pulley driven by the wiper arm pivoting motion drive and over a second pulley mounted on the lower part of the wiper arm, and is attached to the telescopic part of the wiper arm, and a pulling-in cable which is made up of both the lengths of cable (8,9) and passes from the pulley (10) mounted on the telescopic part of the wiper arm back to the driven pulley (18).
