Abstract: PROBLEM TO BE SOLVED: To increase the current density of a normally wound high-conductor density coil through increase in the conductor density of the coil by normally winding an insulated wire manufactured by coating a copper wire having a specific diameter with a polyamide-imide resin coating having a specific film thickness proportional to the diameter of the copper wire. SOLUTION: A normally wound high-conductor density coil uses a copper wire, having a diameter of 0.5-0.04 mm as the conductor of the coil. The copper wires is coated with an insulating film, having a thickness which is 0.5-2.0% as thick as the diameter of the copper wire. In order to meet the electrical, mechanical, and heat-resistance requirements of the coil using the thin insulating film, the film is formed of a polyamide-imide resin or polyester-imide resin. Both the resins have main chains in their structural formulae. Therefore, the resins have very high heat resistances, high mechanical strengths, and good electrical characteristics and enable the copper wire to exhibit satisfactory performance as the electric wire of the normally wound coil, even if the films are thin.  In addition, the conductor density of the coil can be improved to 75-86%, because the conductor ratio of the coil can be increased to 92-98%.

Title: Electron microscope
Inventor: SHINKAWA TAKAAKI
IPC: H01J37/21
Filed: 1989-09-08
Abstract: PURPOSE:To allow smooth adjustment of a focal point and an axis while shifting a magnification in observation into a high level by keeping the shift of an image constant, regardless of any magnification, in observation on a displaying means when signals are supplied to lens means or a deflecting means. CONSTITUTION:In a memory attached to a CPU 13, data are stored which show magnification in observation and the amplitude of wobbling signals. The wobbling signals which are produced by the CPU 13 through the read-out of the data have different amplitude values corresponding to a magnification in observation. The amplitude values of the signals are set so that the shift of an image on a display device can be kept constant regardless of any magnification. On this account, in case of adjusting a diaphragm axis using a wobbler while shifting a magnification in observation into a high level, the shift of the image is kept always constant to allow smooth adjustment of the axis.
