Title: Developing device
Inventor: FUKUDA MOTOYUKI
IPC: G03G15/09
Filed: 1991-11-29
Abstract: PURPOSE:To develop a line in the rotating direction of a photosensitive surface and a line in a direction orthogonally crossed with the rotating direction of the photosensitive surface to have nearly the same thickness by providing a magnetic member which is arranged so that at least a part of a periphery may be faced to a direction which is not orthogonally crossed and not parallel with the rotating direction of a sleeve in substance on the surface of the sleeve and which has specified form by which the magnetic flux density of a magnetic pole arranged on a photosensitive surface side is changed. CONSTITUTION:In the case of seeing the sleeve 2 of a developing roller 1 from the photosensitive surface side, a magnetic member 4 spirally formed is formed as a belt- shaped area which is inclined, for example, by 45 deg. to the rotating direction of the sleeve 2. Then, the high magnetic permeability area of the magnetic member 4 and the low magnetic permeability area of a sleeve base substance 8 are alternately arranged to be a striped pattern. Therefore, the magnetic toner attracted to the surface of the sleeve 2 is formed to be a magnetic brush whose density is higher than that of a magnetic brush at the part of the sleeve base substance 8 along the belt shape of the member 4 in a state where it is inclined by 45 in a developing direction. Thus, an electrostatic latent image is developed in nearly the same thickness regardless of the direction of the surface of a drum.

Title: Electrostatic attracting equipment
Inventor: SAKAKIBARA YASUSHI
IPC: H01L21/683
Filed: 1990-11-21
Abstract: PURPOSE:To eliminate the uneven distribution of attractive force caused by a bias voltage, by a method wherein, before plasma is formed, two plate electrodes are charged so as to have mutually different polarities, and after plasma is formed, the two plate electrodes are positively charged to the earth. CONSTITUTION:In flat plate electrodes constituting an electrostatic chuck 21, two flat plate electrodes 1A, 1B are arranged in a plane along an insulating layer. A power supply for generating attractive force between the electrodes 1A and 1B is constituted of three DC power supplies 4A, 4B, 4C whose terminal voltages are equal. The one electrode 1A is always positively charged to the earth with the DC power supply 4A. Before plasma is formed, the other electrode 1B is negatively charged to the earth with the DC power supply 1C, via a changeover switch 7. After plasma is formed, the electrode 1B is positively charged to the earth with the DC power supply 4B, by changing-over the switch 7. The electrodes 1B generates the same attractive force as the electrode 1A with respect to the wafer 3. Thereby uniform attractive force retains the whole surface of the wafer 3, on the surface of the insulating layer 2.

Abstract: PURPOSE:To decelerate the lifting speed of a lifter plate and to prevent the position variation of a work on the lifter plate by providing a lifter transmission mechanism in which three elastic bodies having different characteristics are combined. CONSTITUTION:The lifter plate 26 carries out elevating and lowering operation according to displacement of a pusher pin 21 by elevating and lowering operation of an upper die 7. In the three elastic bodies S1, S2 and S3 interposed between the pusher pin 21 and a case 22, at the time of lifting the lifter plate 26, the elastic body S2 of the middle stage starts to extent after the elastic body S1 of the lower stage finishes to extend and further, the elastic body S3 of the upper stage starts to extend in parallel to the elastic body S2 of the middle stage from the middle of extension thereof. Accordingly, since the speed of the lifter plate 26 is decelerated as it is lifted, surging of the respective elastic bodies S1, S2 and S3 when the lifter plate 26 is stopped at the lifted position and the positional deviation of the work W on the lifter plate 26 in accordance with it can be prevented. Accordingly, trouble at the time of conveying the work after press work can be prevented.

Title: Peak detector
Inventor: BEERUUZU ERU ABUDEII
IPC: G01R19/04
Filed: 1990-11-26
Abstract: PURPOSE: To detect the positive peak voltage level of an input signal by charging a capacitor up to the positive maximum peak voltage of the input signal in the case of an output signal, and outputting the voltage across it through a buffer circuit. CONSTITUTION: In the case that input signal voltage is larger than output signal voltage, the total current IT of constant current source 13 passes through a transistor 10, and one transistor 12 is off. Therefore, the total current IT/2 of a constant current source 17 runs through the base of a transistor 22, so that a capacitor 24 is charged with the current where the current amplification factor is multiplied by IT/2. A differential amplifier pair consisting of transistors 26, 28 functions as a buffer circuit for converting the voltage across the capacitor 24 into the output voltage to a terminal 16, therefore, the voltage across the capacitor 24 indicates a positive peak voltage level in a terminal 14. It is thus possible to obtain the positive peak voltage level from the terminal 16 as an output signal.
