Title: Electrolytic washing method of cold rolled steel strip
Inventor: MIZUKAMI SUSUMU
IPC: C25F1/00
Filed: 1982-02-26
Abstract: PURPOSE:To prevent the generation of scratching flaws in the stage of unwinding of a coil and the contamination of electrode surfaces during electrolysis, by changing over the polarities of the final electrode before the prescribed wall thickness of the coil is attained in the stage of washing a cold rolled steel plate electrolytically in a sodium silicate bath and coiling the same. CONSTITUTION:A cold rolled steel strip is passed through an electrolytic cell 2 of sodium silicate bath prior to box annealing and the electrolytic washing is started at a positive electrode polarity. A signal is fed to a switch 5 by using the value of an operator 4 for winding diameter before the winding diameter of the coil wound on a tension reel 3 attains at least 50% the final diameter of the coil. A controller 6 upon receiving said signal changes over the polarities of the final electrode wherein the adjacent polarities of respective plural cell pairs are unified and arranged to a positive electrode polarity, and the electrolytic washing is continued. The generation of seizure in the stage of annealing and flawing in the stage of unwinding is prevented and the contamination on the cathode surfaces during electrolysis is reduced by the above-mentioned method.

Title: Track controller for recording medium
Inventor: AOKI YOSHITO
IPC: G11B21/08
Filed: 1993-02-19
Abstract: PURPOSE:To suppress the increase in the traverse speed of a head in the process of adjusting a positional deviation signal and to rapidly and precisely adjust the positional deviation signal by detecting the speed when the head traverses a track and controlling the head at the time of the gain adjustment and the offset adjustment of the track positional deviation signal. CONSTITUTION:The operation suppressing the moving speed V of the head is performed at every fixed time T2 when a head moving speed becoming a limit for precisely adjusting the track positional deviation signal, that is, a limiting speed is regarded as VLM. The moving speedy V of the head is obtained from the variable amount of a track counter 15 for the time T2 and a moving direction detection means 14 in a moving speed detection means 17. Whether the speed V is faster or slower than the limiting speed VLM is detected. When the V is faster than the VLM, a reduction speed E with a fixed value E0 is outputted in a direction that the head speed is reduced. E=E0.sgn(V), where, sgn(V)=1 when V>0, and sgn(V)=0 when V<0.

Title: Overcurrent protection material and fuse using it
Inventor: YOKOZAWA MASAMI
IPC: C22C13/02
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To provide an electric material having a low melting point and high sensitivity by containing at least lead and bismuth, and tin as a main constituent. SOLUTION: This overcurrent protection material contains tin as a main constituent, but has a low melting point, being excellent in workability and is suitable for a material for a high-sensitivity fuse. Since it uses relatively inexpensive tin as the main constituent, this material is prsferable from the viewpoint of a manufacturing cost. The overcurrent protection material should have a solid phase line, for instance, possibly at 140 deg.C or below, and preferably at 120 deg.C or below. When a composition of which the solid phase line in a melting point chart is located in a low temperature region, a liquid phase is produced in the low temperature region. The production of the liquid phase at low temperatures is advantageous for the overcurrent protection material. A temperature at which the solid phase line is present is further preferably 100 deg.C or below.  Preferably, the overcurrent protection material comprises 2-6 wt.% of lead and 4-8 wt.% of bismuth, and the remainder is substantially comprised of tin. Because the content of lead is 6 wt.% or less, it is particularly preferable from the viewpoint of environment protection.

Title: Duplexing file system by bus extended adaptor
Inventor: KIMURA TOSHIYUKI
IPC: G06F12/00
Filed: 1989-02-09
Abstract: PURPOSE:To eliminate the changing work of a program by asserting a BUSY signal so that the next bus cycle is not started, in the case when a conclusion signal (ACK) is not asserted before the operation of a master side is completed, and switching the master and the slave and allowing them to execute a reoperation, when a time-out signal is outputted. CONSTITUTION:When a file adaptor is brought to access and the file adaptor executes no answer, when a time-out monitoring circuit 21 on a bus extended adaptor operates and a time-out signal is generated, an error (ERROR) signal is sent out to the other of a pair of bus extended adaptors, and also, an interruption request IRQ is outputted and informed to a CPU 1. When the IRQ caused by the ERROR is received, the CPU 1 recognizes a fact that the present data transfer ends in failure, and executes a retry (reoperation). In such a manner, the changing work of a program can be eliminated, and also, a time loss for the processing can be decreased.
