Abstract: PURPOSE:To prevent a bad influence caused by the leaked magnetic flux of an actuator by providing a magnetic head in the tip part of a second arm, which is turned in a direction orthogonal to the surface of a magneto-optical disk by a support shaft provided in the tip part of a first arm, and balancing the weight of the second arm to the support shaft. CONSTITUTION:A magnetic head 1 is fitted to one end of a second arm 2 and the second arm 2 is turned with a support shaft 4, which is fitted to a base 3, as a center. Then, a coil 5 is fixed to the other end of the second arm 2. A magnetic circuit, which is composed of a magnet 6 and a recessed yoke 7, is fitted to the base 3 and an electrodynamic driving mechanism is formed by making the magnetic flux interlink one part of the coil 5. In such a case, the second arm 2 balances the weight between the magnetic head side and coil side with the support shaft 4 between. Thus, since a supporting point is provided in the arm and the weight is balanced in the both sides, force caused by gravity is not applied to a dumper for reference position return and there is no danger of a change with the passage of time. Then, since a driving part is arranged in a side opposite to the magnetic head with the supporting point of the arm between, the surface of the magneto-optical disk is not affected by the leaked magnetic flux.

Title: Chattering preventing circuit
Inventor: OGURA TAKAYUKI
IPC: H01H9/54
Filed: 1987-06-04
Abstract: PURPOSE:To prevent the chattering to occur at the time of the on and off of a single contact by providing a pulse generating means to generate a prescribed period pulse, a differential means connected to the output and a memory means to output a signal corresponding to an input signal and the time point of a differentiated output. CONSTITUTION:When an input signal is changed, for example, from on to off, a pulse generating means 70 outputs the pulse of a constant period. At this time, chattering to occur by changing over a switch occurs at the input signal to the means 70, and since the interrupted time is short, the pulse of a constant value included in the above-mentioned pulse is outputted for a constant period. The output is inputted to a differential means 80 and differentialized by the fall part. The differentiated output is added to one side input of a memory means 110 and a signal to branch the input signal is added to other input. At the means 110, a pulse which comes to be on when the input signal is on and comes to be off by the output of the means 80 is outputted.

Title: Fluorination method
Inventor: YASUDA ARATA
IPC: C07C67/00
Filed: 1983-08-02
Abstract: PURPOSE:To carry out the selective substitution of trimethylsiloxy group of an organic compound having trimethylsiloxy group bonded to a carbon atom with fluorine atom, by fluorinating the compound with an aminosulfur fluoride-type fluorination agent.

Title: Control system for structure of data processing system
Inventor: INOUE MASANOBU
IPC: G06F15/16
Filed: 1986-06-16
Abstract: PURPOSE:To maintain a system so as not to introduce break down in the tilled system capable of dynamically switching a couple (C) mode and a separate (S) mode by permitting a SVP to hold and control information on failure of each device and exchanging information controlled as separate systems so as to process in a lump when the operation shifts from the S mode to the C mode. CONSTITUTION:If a CPU 10 develops failure, it instantaneously stops operations under execution, and notifies the service processor SVP 16 of the failure. After the SVP 16 logs out the inner state of the CPU 10, it judges whether a retrial is possible or not. If so, the inner state of the CPU 10 is restored to the state of beginning the retrial, and the retrial is activated. If it proves successful, operations continue. If it fails, the CPU 10 is isolated from the system, and tasks that the CPU 10 is executing are shifted to a CPU 11, and a simular retrial is executed. If the troubled part in the CPU 10 can be separated, like a cache memory, a partial separation is made, and a retrial is conducted. In that case the retrial proves successful.

IPC: B22D7/06
Filed: 1983-08-01
Abstract: PURPOSE:To improve the contact between a casting and water-cooled copper plates and to cast a steel ingot having no internal defects in the stage of casting the steel ingot with an upward expanded casting mold consisting of long-side plates and short-side plates by attaching the water-cooled copper plates to the inside of the long-side plates and making the same movable toward the inside. CONSTITUTION:Water-cooled copper plates 10A are attached to the inside of the long- side plates 8 of a casting mold formed of the long-side plates 8 and short-side plates 12 so as to expand upward at an angle theta on the double molding boards 2B on a molding board 2A. A clearance 11 is provided between the bottom end thereof and the boards 2B and is kept closed with asbestos, etc. A molten steel 32 is cast by bottom pouring through a pouring pipe 4 and a runner 6 into the casting mold. The molten steel begins to solidify from the surface in contact with the boards 2B and the plates 10A and forms a solidified shell 34. The steel ingot shrinks on progressing of the solidification and a clearance is made between the shell 34 and the plates 10A and therefore the plates 12 are moved upward to form a spacing from the plates 8. The plates 8 are pressed by hydraulic cylinders 30 to bring the plates 10A into contact with the solidified shell at all times. The decrease in the cooling speed of the steel ingot is obviated and the steel ingot having no internal defects such as reverse V segregation, porosity, etc. is produced.
