Title: Manufacture of chrome plated cast iron roll
Inventor: SASAKI TSUYOSHI
IPC: C25D5/36
Filed: 1988-10-17
Abstract: PURPOSE:To make a roll usable under high loads and to prolong service life of the roll by increasing the number of peaks on the roll surface by specific numbers than the number of peaks before treatment by performing electrolytic treatment and chrome plating the roll in a chrome plating bath. CONSTITUTION:Before chrome plating on the surface of a cast iron roll containing >=2.0% C, by wt. is performed, the roll surface before electrolytic treatment is dull finished to have roughness corresponding to using purposes of the roll. Then, the roll is electreolytically treated by bringing the roll to an anode in an electrolyte to increase the number of peaks on the surface by 1-50% larger than that before the electrolytic treatment. Alkali and water washings of the roll are performed after the treatment and the roll is chrome plated by bringing the roll to a cathode in a chrome plating bath. Hence, the roll is usable under high load operations such as skin-pass rolling and cold rolling and service life is also prolonged.

Title: Apparatus for detecting normal conduction transition of superconducting magnet
Inventor: AIHARA KATSUZO
IPC: H02H7/00
Filed: 1985-11-22
Abstract: PURPOSE:To provide an apparatus for detecting normal conduction transition which does not operate errorneously when a plurality of superconducting magnets are combined, by providing a plurality of detection circuits for detecting normal conduction transition and generating a signal in a bridge circuit including a superconducting magnet coil as one side thereof. CONSTITUTION:When a superconducting magnet 1' is in the stop condition, a superconducting magnet 1 is excited. Normally, the bridge voltage to a circuit 5' for detecting normal conduction transition will be out of balance, generating a transition signal to an AND circuit 11, but since the bridge voltage to a circuit 5 for detecting normal conduction transition will not be out of balance, the transition signal to the AND circuit 11 is not generated, so a normal conduction transition signal is not generated at 12. Further, the superconducting magnet 1 is excited, and if normal conduction transition occurs, a transition signal is also generated from the circuit 5 for detecting normal conduction transition, and a normal conduction transition signal is generated at 12 by the AND circuit 11. Since this does not operate errorneously even against disturbance which is generated at the time of mutual induction, a highly reliable system for detecting normal conduction transition of a superconducting magnet is obtained.

When the mass matrix of the blade 9 is denotes as M, the modal mass m*=circumferential modal mass my*+axial modal mass mt*=phiy<t>Mphiy+phit<t>Mphit. A mode wherein the shaft 10 is twisted actually is only the mode phiy, so only the component phiy becomes interconnected mass mc* and then mc*=1<t>Mphiy. Therefore, an interconnected coefficient a=mc*/m*. Then equivalent mass meq, an equivalent spring keq, and additional residual mass DELTAm to the boss part 11 are determined and substituted to generate the target equivalent reduced model. Consequently, however complicate motion the blade 9 is in, the accurate reduced model is obtained.

IPC: G06F17/10
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To reduce the number of required clock cycles by detecting an accuracy bit relating to a solution, judging whether or not rounding calculation is required and setting the correction factor of the solution corresponding to the detected accuracy bit and a rounding mode when the rounding calculation is required. SOLUTION: In order to start the rounding calculation, a fix-up detector 60 asserts an RND-CALC line in the same clock cycle as the one for confirming the values of bits 53-56 and outputs control signals ACC-COL-CNTL to a latch. A floating point device controller responds to the assertion of the RND-CALC line, feeds an instruction relating to the rounding calculation, controls a multiplexer and outputs a round-down solution. Then, the latch outputs the control signals ACC-COL-CNTL to a multiplier and as a result, '1' is set to the name bit of a correction factor column. Then, a 54-th bit is added to a TEMP mantissa and the correction factor is introduced.

Title: Dispersion for optical element
Inventor: YOSHINO YUICHI
IPC: G02F1/19
Filed: 1990-10-02
Abstract: PURPOSE:To prevent the sticking of anisotropic particles to electrodes at the time of impressing an electric field without disturbing the optical characteristics of dispersion by dispersing the particles transparent to a dispersion medium together with the anisotropic particles into this medium. CONSTITUTION:The anisotropic particles 7 arranged in parallel of a cell 2 move back and forth in the electric field direction while rotating and vibrating according to the fluctuation in the AC electric field while the AC electric field is held impressed to this cell. The transparent particles 8, however, exist around the anisotropic particles 7 and the anisotropic particles 7 collide against the transparent particles 8. Namely, the transparent particles 8 act as obstacles to hinder the movement of the anisotropic particles 7. Then, the anisotrpic particles 7 cannot easily collide against the electrodes 5 anymore and the degree that the density of the anisotropic particles 7 decreases near the electrodes 5 decreases. The movement of the anisotropic particles 7 positioned in the parts apart from the electrodes 5 near to the electrodes 5 is suppressed.

Filed: 1992-09-03
Abstract: PURPOSE:To prevent the deterioration of the withstand voltage and quality of an aluminum oxide film when the film is impregnated with a metal oxide by using a mixture of lead dioxide and manganese dioxide as a solid electrolyte. CONSTITUTION:After electrode foil having a surface magnification of about 50 times is manufactured by performing electrolytic etching on highly pure aluminum foil having a thickness of 90mum, a dielectric film is formed by subjecting the electrode foil to 30V chemical conversion treatment with a neutral phosphoric acid solution. Then, after preparing a 100g/l aqueous solution of potassium permanganate and 300g/l aqueous solution of lead acetate, both aqueous solutions are mixed with each other and the electrode foil is impregnated with the mixture immediately after preparing the mixture. The electrode foil is left as it is for 30 minutes at a room temperature so that lead dioxide and manganese dioxide can deposit on the electrode. Thereafter, the title electrolytic capacitor is manufactured by applying colloidal carbon to the surface of the electrode, forming cathode leads with silver paste, and coating the surface with an epoxy resin. The capacitor thus manufactured is improved in leakage current characteristic and, since the capacitor has an excellent impregnating ability, increased in capacitance.
