Abstract: PURPOSE:To reduce inter-strand coupling loss by dipping a complex element wire in a plating bath of predetermined ingredients for electroplating, and forming a Cr plating layer having a predetermined thickness, followed by heat- treatment. CONSTITUTION:A complex element wire made of an Nb wire of about 3.4mum diameter and Cu-about 4.3% Sn alloy is electroplated in a plating bath of chromic acid anhydride and sulfuric acid under a predetermined condition, and a Cr plating layer is formed to be about 1-20mum in thickness and in the case of plural layers to be 3-20mum in total thickness. Fine pinholes are formed on the surface of the element wire by the action of sulfuric acid and metal Cr is deposited so as to form the Cr plating layer having a high degree of adhesion. The strand made of this covered wire rod by heat-treatment at a predetermined temperature shows excellent results in respective electric characteristics such as a contact resistance value, residual resistance ratio, specific resistance value, coupling loss time constant of a conductor. Thereby it is possible to reduce an inter-strand coupling loss of a large current superconductive conductor.

Title: Automatic temperature regulation type heater having excellent efficiency
Inventor: FUIRITSUPU ESU KAATA JIEIAARU
IPC: B23K3/047
Filed: 1985-10-24
Abstract: The impendance of an autoregulating heater is greatly increased by employing in one embodiment a return conductor in the form of a helix surrounded by and insulated from a magnetic conductor; the two conductors connected in series or as a transformer across an a.c. source whereby the current in the magnetic material is forced to follow a helical path. In a preferred embodiment, a multilayered coil is wrapped about and insulated from a magnetic sleeve disposed about a copper rod; the sleeve and rod forming the secondary of a transformer. The helical path of the current in the secondary plus the impedance transformation effect of the transformer greatly enhances the impedance of the load as presented to a current source. The winding is enclosed within another magnetic sleeve which provides another magnetic shield about the heater and if connected at one end to the inner magnetic layer increases the width to thickness ratio for purposes to be described.

Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent an abnormal drop of the battery voltage of a camera during image blurring correction without generating a large discrepancies between the objective value of an image blurring correcting amount and an actual value. SOLUTION: During the execution of an image blurring correction by driving motor driving circuits 8 and 9, when the dropping of a power supply voltage VB more than a specified value V1 is detected, a CPU 2 limits an input voltage Vin applied to each of the motor driving circuits 8 and 9 to a maximum voltage value by which the dropping of the power supply voltage VB more than the specified value V1 is prevented. Thus, a voltage Vout applied to each of motors 11 and 12 is limited to a maximum voltage value by which the dropping of the power supply voltage VB more than the specified value V1 is prevented, current consumption inside the camera is controlled and the power supply voltage VB is increased.
