Title: Ion implantation method
Inventor: TOYODA HIROYUKI
IPC: H01L21/265
Filed: 1985-06-24
Abstract: PURPOSE:To ensure a prompt and sure neutralization of electric charges that accumulate during an ion implantation process by a method wherein a conductive film so thin as to let ion beams through is built on the entirety of a semiconductor wafer primary surface whereon a mask is formed and the implantation of ions into the semiconductor wafer is accomplished simultaneously with the supply of electrons into the conductive film. CONSTITUTION:A semiconductor wafer 1a is provided, on its primary surface to be implanted with ions, with an insulating surface layer 9 and resistance layer 10 as in a conventional method. Thereafter, a conductive film 12, for example a metal film deposited by evaporation, is formed to cover the entire primary surface. A process follows wherein a mask 11 is selectively formed on the conductive film 12. Ion implantation is accomplished while electrons are supplied to the conductive film 12 through clampers 5. The electrons introduced into the conductive film 12 steadily neutralize the positive electric charges generated in the insulating surface layer 9 and resistance layer 11 during ion implantation, which eliminates the possibility of electric charges excessively accumulating.

Title: Magnetic shield for axial fan
Inventor: ITO TAKAHIRO
IPC: H02K7/14
Filed: 1995-06-06
Abstract: PURPOSE: To shield the leakage flux while eliminating loss of air flow by disposing shielding plates having outside diameter larger than that at the rotor section and high permeability at the rotor section and a rotor supporting section and coupling the shielding plates magnetically through a shielding band member having high permeability. CONSTITUTION: The magnetic shield 20 comprises shielding plates 21, made of a material having high permeability and having outside diameter larger than that at a rotor section 3, disposed closely to the rotor section 3 and a rotor supporting section 4 and perpendicularly to the direction of rotary shaft of an axial fan motor 1 in front and rear thereof in the flow direction. The shielding plates 21, 21 are coupled magnetically through a plurality of shielding band members 22, 22 made of a material having high permeability and disposed symmetrically with respect to the rotational axis of motor 1. Since the flux leaked from the rotor supporting section 4 passes through one shielding plate 21, the shielding band member 22, and the other shielding plate 21 and flows into the rotor part 3, the flux can be prevented from leaking to the air.

Title: Information recording and reproducing device
Inventor: ITO KENICHI
IPC: G11B7/085
Filed: 1988-06-06
Abstract: PURPOSE:To obtain the follow-up property to a target position with high stability by using a signal which has added outputs of first and the second compensating means as a driving signal of the second driving means for moving a light spot extending over a recording area of a recording medium. CONSTITUTION:To a tracking actuator 13, a driving signal VA is inputted, and a displacement detecting means 14, a displacing signal X'A of the tracking actuator 13 is detected. As for this displacing signal X'A, its high frequency component (X'A)H is fetched through a high-pass filter 15, and as for the driving signal VA, its low frequency component (VA)L is fetched through a low-pass filter 16. The low frequency component (VA)L which has been fetched is added to the high frequency component (X'A)H by an adder 18 through an amplifier 17 having a suitable gain K in order to allow the sensitivity to conform with the high frequency component (X'A)H. An output XA of the adder 18 is obtained by (X'A)H+K.(VA)L, and becomes a driving signal of a linear motor. In such a way, a complicated adjustment becomes unnecessary, and the follow-up property to a target position is secured with high stability even against a temperature variation.
