Title: Electrification quantity distribution measuring method
Inventor: TAKEUCHI TATSUO
IPC: G01R29/24
Filed: 1990-05-10
Abstract: PURPOSE:To execute the separation, the catching and the measurement even in the case an electrification characteristic of toner particles is biased by applying an alternating electric field of a different duty ratio between a developer carrying member and an electrode which is opposed thereto and has an air inflow port. CONSTITUTION:When an alternating electric field is applied to an electrode plate 3 from an AC power source 10, and a developer carrying member 2 is grounded, in the case a voltage exists on the + (-) side, an electric line of force goes to the member 2 from the electrode plate 3, and toner particles T electrified to negative (positive) polarity contained in a developer 1 are separated from the member 2, go to the electrode 3, and are sucked by an air flow 5 which flows in toward the inside of a separating/carrying part A from its slit 4. In the case, the particles T are electrified to negative (positive) polarity, an alternating electric field in which an electric field in the negative (positive) direction is large, for instance, an alternating electric field of 33% duty is applied to the member 2. Also, the applied electric field is set so that the total quantity of the electric fields in the position and the negative directions becomes equal, when the time integration is executed. In such a way, since the duty ratio is made different, catching can be executed centering around the particles having a high triboelectrification quantity.

Abstract: PURPOSE:To obtain an ion implantation method which eliminates the electrification of particles, prevents a charged-up state and can measure also the amount of implantation by a method wherein an ion beam and an electron beam are mixed in a first magnetic field and the ion beam which has separated the excess electron beam is implanted into a wafer in a second magnetic field. CONSTITUTION:A positive ion beam is impinged on a metal cylinder 11 from a positive- ion generator 6; an electron beam is impinged from a window situated on the side face of the metal cylinder 11 from an electron gun 14 from a direction which is different from that of the positive ion beam. The electron beam and the positive ion beam are mixed and neutralized in a first magnetic field 15; neutralized ions and excess electrons are impinged on a second magnetic field 12. The motion direction of the neutralized ions is not influenced by the magnetic field; the motion direction of the electrons is changed by the magnetic field. Thereby, the neutralized ions are implanted into a semiconductor wafer 3, and the excess electrons are collected by the metal cylinder 11. When an electric-current amount by a measuring instrument 4 is zero, it is found that the positive ion beam has been neutralized completely; an ion implantation amount can be measured by means of an electric-current amount by a measuring instrument 13.

Title: Method for calculating diffraction angle of computer hologram
Inventor: MATSUO HARUO
IPC: G03H1/08
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To substantially eliminate the distortion of reproduced image even if a diffraction angle is increased and to increase the degree of design freedom of a reproduction device by correcting the positions of a light source and a screen by using the position information of the light source and screen with respect to a coordinate system when the diffraction angle at a computer hologram (CGH) is calculated. SOLUTION: The position of the screen of the CGH reproduced image, the position of the light source (BS) and the position of CGH are determined (S1). A CGH pattern is designed (S2). The coordinates of BS, CGH and the spot on the screen are determined (S3). The coordinates of the screen are converted (S4). The diffraction angles in (x) and (y) directions of the diffracted light in the transmission type CGH are calculated from BS, CGH and the spot on the screen (S5). When CGH is formed by using these diffraction angles, correction is necessary in the case the reproducing light is made incident at an angle exclusive of perpendicularity. This correction is fitted to the calculation using the diffraction angle when the reproducing light is made incident perpendicuarly on the surface of CGH after the calculation of the degree of distortion is carried out reversely.

Title: Device for discriminating recording system of magnetic tape
Inventor: MIHASHI TAKAMICHI
IPC: G11B5/027
Filed: 1983-06-30
Abstract: PURPOSE:To discriminate whether a frequency-modulated sound signal is recorded or not precisely and instantaneously by detecting the amplitude of a video signal in a horizontal flyback time from a signal component in a prescribed band from the high band part of a carrier color signal converted into a low band part to the low band part of a frequency-modulated luminance signal. CONSTITUTION:When a frequency-modulated voice signal is recorded in the prescribed band Bs from the high band part of a carrier color signal CL to the low band part of a luminance signal YF, sound signals LA, RA are obtained from the outputs of filters 21L, 21R by a head 1A and sound signals LB, RB are obtained from the outputs of filters 22L, 22R by a head 1B. Consequently, frequency-modulated sound signals are continuously obtained from the output of a switch 31 and the amplitude of a signal Sx from the output of the switch 31 is sufficiently increased even in the horizontal flyback time of a video signal. Therefore, the detected voltage SA of the output of an amplitude detecting circuit 32 is always higher than a reference voltage VR, so that a signal SD from the output of a monostable multivibrator 34 is always held at a low level.
