Title: Screening method for semiconductor device
Inventor: YANAGI YUJI
IPC: H01L21/66
Filed: 1985-05-14
Abstract: PURPOSE:To enable the elimination of the damage of a semiconductor device having no defect and to apply to the semiconductor device having a constant-voltage circuit by applying a high frequency voltage. CONSTITUTION:An insulating film 2 of the first layer is formed on a semiconductor substrate 1, a conductor 3 of the first layer such as aluminum is formed on the film 2, an interlayer insulating layer 4 of the insulating film of the second layer is formed on the conductor 3, and a conductor 5 of the second layer is further formed. In this process, a defect 6 occurs at the time of forming the film 2 and the conductor 3. When a high frequency voltage is applied between the conductor 3 of the first layer and the conductor 5 of the second layer, power is consumed by the layer 4 of a dielectric unit concentrically at the defect which is reduced in the thickness of the insulating film. Even if a semiconductor controller which contains a constant-voltage circuit in a power source is provided, the voltage is affected to the defect of the insulating film in the device. Therefore, it is not necessary to apply a high voltage to the semiconductor device, and even if the semiconductor device contains a constant-voltage circuit in the power source, a stress can be concentrically applied to the defect 6 of the film 4 to shortcicuit it in a short time, thereby picking up the semiconductor device having an internal defect.

Title: Drawing control system
Inventor: MATSUDA JIRO
IPC: G06F17/50
Filed: 1988-04-22
Abstract: PURPOSE:To image a drawing exactly equal to the original one with a simple operation by using a transmission/reception means for graphic information, a means which converts the received graphic information into the picture information, and a means which stores the graphic information and the picture information related with each other. CONSTITUTION:When the graphic information delivered from a CAD system 1 is stored in an optical disk 9, this information is received by a transmission/ reception part 4 via a control part 3 and written into a file part 5 for each reception. Then the part 4 decides the reception of all graphic information forming a sheet of drawing in case no graphic information is received for a fixed time. Hereafter the part 4 interprets the received graphic information and calculates the maximum coordinate point to be drawn from a graphic identifier and a parameter. Thus the size of the drawing is decided and written into the part 5 when the graphic information is converted into the picture information. Then the drawing size information is produced at the part 5 together with the graphic information byte number and the graphic information forming a sheet of drawing. Thus it is possible to image a drawing exactly equal to an original one with a simple operation.

Title: Separating device
Inventor: SAITOU JIYUN
IPC: G03G15/00
Filed: 1982-06-11
Abstract: PURPOSE:To prevent a separating member from deforming when a separation part is inserted and to eliminate sheet contamination due to the contamination of the separating member, by using the separating member which has curling characteristics perpendicular to a tension direction for separating a sheet after transfer from an image carrier. CONSTITUTION:When a separating and conveying part after jam processing is inserted into a photoreceptor 1, a separating belt 42-2 uses a material which has curling characteristics perpendicular to the tension direction as shown by a chained line 42-2a and curls projecting to the side of a photoreceptor 1, and the edge of the separating belt 42-2 on the engaging side with transfer paper is beveled so that the extent of engagement with the paper decreases in the conveyance direction of the paper. Therefore, even when the separating and conveying part contacts the end part of the photoreceptor 1 when inserted, the belt 42-2 is easy to move away from the photoreceptor 1 by the synergistic effect between the curling characteristics and the inclination of the edge and the belt never deforms.
