Title: Electrostatic charging device
Inventor: NAGASE YUKIO
IPC: H01T19/00
Filed: 1987-09-24
Abstract: PURPOSE:To charge an object member uniformly and electrostatically by providing a means which corrects electrostatic charging ability uniformly corresponding to the film thickness distribution of a 2nd dielectric. CONSTITUTION:A discharging member 1 consists of 1st and 2nd electrodes 4 and 5 embedded in 1st and 2nd dielectrics 2 and 3 and a bare electrode 6 as a 3rd electrode, and a discharge-resisting film as the 2nd dielectric 3 has an irregular film thickness distribution. Here, the 3rd electrodes 6 applied with a bias voltage is so formed that a part having larger film thickness is closer to the center of an AC discharging area 10 between the 1st and 2nd electrodes according to the film thickness distribution of the 2nd dielectric 3. Namely, the intensity of an electric field is larger and larger toward to the center of the discharging area, so the 3rd electrode 6 is put closer to the center of the discharging area to improve the electrostatic charging ability for increasing the attracting-out quantity of ions. Consequently, a charging current has uniform distribution characteristics and an irregular electrostatic charging current distribution due to the irregular film thickness distribution can be eliminated.

Title: Time synchronization system
Inventor: FURUYA TSUKASA
IPC: G06F1/14
Filed: 1988-09-27
Abstract: PURPOSE:To provide a precise time for plural devices by providing two counters, and constituting a correcting circuit for eliminating errors between the devices. CONSTITUTION:A first counter 10 receives a simultaneous notice signal, initializes a content, and starts counting up by a bus cross 52. The devices normally have the present time in a second counter 11, and the device obtains the necessary time by using the content. Namely, the first counter 10 performs counting up while the time is read from a main storage, and it has a correction value for the time in the main storage. The output of the first counter 10 and the time in the main storage are added in an adder 12, and are set in the second counter 11. Then, the value of the second counter 11 which has been set is subsequently timed by the bus clock 52 and the accurate present time is always maintained. Thus, the errors of time between respective devices can be eliminated.

Filed: 1996-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a mask positioning method by which the occurrence of the positional deviation of the projected image of a mask pattern can be prevented by adjusting the projecting magnification of a projection optical system. SOLUTION: Prior to the transfer of the image of a pattern formed on a mask R to a photosensitive substrate through a projection optical system PL, the projecting positions of at least two marks 19a and 19b for alignment formed in a prescribed positional relation with the pattern of the mask R before and after the projecting magnification of a projection optical system PL is changed are respectively measured in first and second processes. In a third process, the position of the mask R is adjusted so that the center of the projected image of the pattern cannot change even when the projecting magnification of the optical system PL is changed. Therefore, the occurrence of the positional deviation of the projected image of the pattern of the mask R can be prevented by adjusting the projecting magnification of the optical system PL.

Title: Current lead for superconducting electromagnet
Inventor: TAKITA KIYOSHI
IPC: H01L39/06
Filed: 1990-09-12
Abstract: PURPOSE:To prevent a phenomenon in which the temperature of one current lead excessively rises to become a runaway state by composing hollow tubes of two current leads in a constitution to be coupled by at least one heat transfer member. CONSTITUTION:Current leads 3A, 3B disposed in parallel are coupled by a coupling tube 30 made of an insulating material in such a manner that the inner spaces of hollow tubes 6 of the leads 3A, 3B are coupled.
