Abstract: PURPOSE: To stably produce a non-aging hot rolled steel plate with excellent workability by properly regulating cooling starting temp. after hot rolling and also cooling the resultant hot rolled plate rapidly down to a temp. in a specific range at the time of producing a hot rolled plate of Al killed steel. CONSTITUTION: An Al killed steel slab containing <0.05wt.% C is previously subjected to strain working at 600-750 deg.C to accelerate the precipitation of contained harmful solid-solution nitrogen into the form of AlN. The steel slab is heated to undergo temp. rise up to a temp. in the range between the Ac3 transformation temp. and 1000 deg.C and hot-rolled at a temp. not lower than the Ar3 transformation point. Cooling is started within 0.5sec after the finishing of hot rolling to prevent the re-entering into solid solution of precipitated AlN and to improve workability. The hot rolled plate is cooled rapidly down to 250-450 deg.C at >=20 deg.C/sec cooling rate and held at this temp. for at least 60min to precipitate solid-solution carbon in the steel as cementite (Fe3 C) and to improve the non-aging characteristic of the steel.  By this method, the non-aging hot rolled steel plate, satisfying TS×EL>=15000MPa, having <=30MPa aging index AI, and excellent in workability, can be inexpensively produced.

Abstract: PROBLEM TO BE SOLVED: To operate a file according to its sorting for any sorting index and to prevent the operation defined based on a specific sorting index from being sacrificed by defining the sorting item of every index as an attribute if plural indexes are available to sort the files. SOLUTION: The identification of a file defined by a logical expression set by an attribute and an individual file name is used to designate a file based on the condition that is shown in a logical expression concerning the attribute. Meanwhile, a logical expression set by an attribute called a working directory is allocated to a job and only a logical expression that is added to the logical expression of the working directory can be used via the designation of a file. At the same time, a command is added to change the working directory. Furthermore, a command is added to give a new name to a logical expression set by an attribute and this name is called a secondary attribute. This secondary attribute can also be used for the designation of a file that is carried out via a file operation.

Title: Controller
Inventor: NAKAE KAZUMI
IPC: G06F1/30
Filed: 1992-11-30
Abstract: PURPOSE:To prevent the operation stop of a main control circuit on account of the interruption of a power source by restoring a system from a stop mode to an operation mode when power voltage is restored to more than prescribed voltage by an auxiliary control circuit executing a limited interpolation operation instead of the main control circuit when power voltage does not exceed prescribed volate. CONSTITUTION:The operation mode of the main control circuit 12 differs from that of the auxiliary control circuit 13 in accordance with the height of power voltage as against prescribed voltage Va. When the output voltage of a power vicircuit 7 exceeds prescribed voltage Va, the main control circuit 12 is at the operation mode executing a prescribed operation program. When power voltage does not exceed prescribed voltage Va, the execution of the operation program is interrupted and the system shifts to the stop mode suppressing power consumption. On the other hand, the operation of the main control circuit 12 is monitored by the auxiliary control circuit 13 when the output voltage of the power circuit 7 is more than prescribed voltage Va. When power voltage does not exceed prescribed voltage Va, the limited interpolation operation is executed instead of the main control circuit 12, and it is restored again when it exceeds prescribed value Va.

Title: Absolute coordinate value reading system
Inventor: KONDO TAKAHIDE
IPC: G06F3/03
Filed: 1990-11-27
Abstract: PURPOSE:To attain precise coordinate value reading by inputting an average value except a maximum value and a minimum value from a sampled absolute coordinate value to a CPU device. CONSTITUTION:A register R4 inputs the maximum value of a coordinate value obtained by sampling for N times and a register R5 inputs the minimum value of the coordinate value obtained by sampling for N times. Then, comparators 2 and 3 compare the coordinate value inputted in order and the value of the register R4 and the register R5 respectively and it is discriminated whether the coordinate value inputted newly becomes the maximum value or the mini mum value or not. Besides, gates 10 and 11 open when the coordinate value inputted newly is smaller than the value of the register R4 and gates 12 and 13 open when the coordinate value inputted newly is smaller than the value of the register R5. Moreover, a gate 14 opens by a signal from an AND 15 when the coordinate value inputted newly is between the value of the register R4 and the value of the register R5. Thus, precise coordinate value reading can be executed.
