Title: Erasing of data
Inventor: KOYAMA KENICHI
IPC: G11C16/14
Filed: 1992-02-19
Abstract: PURPOSE:To suppress the variation of threshold voltage after erasion by leveling threshold voltage by applying positive voltage after lowering the threshold voltage by applying negative voltage to a control gate electrode. CONSTITUTION:Firstly, a drain diffusion layer is set to be 0V, and a control electrode and a source diffusion layer are applied with pulses of -14V and 5V, respectively, for a floating gate to be charged with positive voltage. Then, the source diffusion layer, the drain diffusion layer and a substrate are set to be 0V, and the control gate electrode is applied with +14V pulses for 0.5 seconds. FN tunnel current flows between the floating gate electrode and the substrate, and electrons are injected into the floating gate electrode. As a result, the floating gate voltage drops so that feedback mechanism is formed between the amount of electrons to be injected into the floating gate electrode and the floating gate voltage. By the feedback mechanism, the floating gate voltage converges into a certain value and the threshold voltage with respect to the control gate electrode, also converges into a certain value, so that the variation of the threshold value can be suppressed.

After being moved over the tip end of a main body 22 at first, the guide tube functions as the major guide wire of the catheter main body 22 and has rigidity sufficient to aid penetrating a tubular organ in a body. Consequently, when the guide tube 30 projects laser energy from the tip end, moves and rotates in the inside of the catheter main body 22 in the longitudinal direction and can move a substantial distance over the end part of the catheter main body. Next, when the catheter main body moves forward in a tubular organ in a body and further removes blocked plaque or tissue, the member 30 is very useful as a guide means of the catheter main body.

Abstract: PROBLEM TO BE SOLVED: To lessen the useless consumption and discarding of a plating liquid and to enhance the recovery efficiency of this plating liquid by sealing the peripheral part of a wafer with a sealing member for the purpose of preventing plating to the peripheral part of the wafer and extending the front end of a plating liquid discharge pipe near to the front surface of the wafer. SOLUTION: The following remedy is executed in order to recover the plating liquid existing in the part lower than the drain piping 5 on the wafer 6, more particularly the plating liquid remaining in the O-ring seal 11. A plating liquid draw-out port is extended near to the surface of the wafer 6 and a second drain piping 17 arranged apart a slight clearance from the wafer 6 is disposed. The recover of the plating liquid is executed by establishing a hermetic state in a plating treatment bath, introducing gaseous nitrogen into the bath from the prescribed piping and forcibly feeding the plating liquid by pressurizing the inside of the plating treatment bath. As a result, the recovery of the plating liquid accumulating in the part lower than the drain piping 5 which is heretofore impossible to be recovered is made possible.

Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To drive an image carrier and a developing roller with a motor having low torque and to prevent the occurrence of the skip of an image and surface staining. SOLUTION: The developing roller 15 is provided with a roller main body 32, a roller shaft 33, a developing region 34 which is formed on the outer periphery of the middle part of the roller main body 32 and brought into contact with the image forming region of the image carrier and large-diameter parts 35 which are set to obtain outside diameters larger than that of the developing region 34 and formed in both end parts of the roller main body 32. Therefore, even if the press-contact force of the developing roller 15 with the image carrier is great, the press-contact force of the developing roller 15 with the image forming region of the image carrier can be suppressed smaller.  Thus, the image carrier and the developing roller 15 can be driven with the motor having the low torque and the occurrence of the skip of the image caused by the peeling of the developer from the image carrier and the surface staining caused by the reverse electrification of the developer is prevented.
