Title: Drive method for solid-state image pickup element
Inventor: KAWAURA HISAO
IPC: H04N5/335
Filed: 1988-10-28
Abstract: PURPOSE:To reduce the after image through the smooth and quick transfer of a signal charge by modulating a potential of a light shield part so as to reduce the charge storage capacity of a photosensor section at signal readout. CONSTITUTION:In order to apply a pulse voltage (e.g., a negative pulse voltage) decreasing the capacitance of the photo sensor section 4 at signal readout, a pulse voltage generator 8 is inserted between a P-type substrate 5 and a light shield section 3. Moreover, solid lines represent a potential just before the signal readout and one-dot chain lines represent a signal charge stored in the photosensor section and dotted lines represent a potential at signal readout. Since a negative voltage pulse is applied to the light shield section 3 at signal readout, the potential of the photosensor section 4 is boosted and the charge storage capacitance of the photosensor section 4 is decreased than that before the readout. Thus, the readout is applied completely and the after image hardly takes place.

Title: Curl removing device for roll paper
Inventor: KANDA TSUTOMU
IPC: B65H23/34
Filed: 1984-12-27
Abstract: PURPOSE:To always exhibit the removing effect of curls in a roll paper, by providing a blade for removing curl in the roll paper, which is moved by a lever member rotating in accordance with the diameter reduction of the roll paper so that the space between the outer surface of the roll paper and the blade is maintained to be constant. CONSTITUTION:A lever member 7 having a press-contact roll 8 which is always urged to be pressed against on the outer surface of a roll paper is rotated clockwise in accordance with the diameter reduction of the roll paper on a wind-up core. In accordance with the rotation of the lever member 7, a curl removing blade 3 attached to the lever member 7 by means of a pin 9 is rotated counterclockwise about a pivot pin 5 as a rotating center. The front end edge 3' of this blade 3 is moved in the direction approaching the wind-up core 1. Accordingly even if the diameter of the roll paper on the wind-up core 1 is reduced, the space between the outer surface of the roll paper on the wind-up shaft and the front end edge 3' of the curl removing blade 3 may be maintained to be constant without being enlarged, and therefore the bent angle alpha the roll paper will not increase thereby the drawing action of the roll paper by the front end edge 3' will be not reduced.

Title: Parallel-plate mim capacitor for integrated circuit
Inventor: KATO TAKAYUKI
IPC: H01G4/33
Filed: 1988-10-28
Abstract: PURPOSE:To obtain a product at a high yield without a breakage by static electricity generated during a production process by a method wherein grounding conductor lines which can be cut at a final stage of the production process are formed individually at an upper-layer metal film and a lower-layer metal film. CONSTITUTION:In a parallel-plate MIM capacitor having a plurality of conductor metal films 2a, 2b between which an insulator film 3 is sandwiched at both sides, grounding conductor lines 5a, 5b which can be cut at a final stage of a production process are formed individually at an upper-layer metal film 2b and a lower-layer metal film 2a. For example, conductor metal films 2a, 2b are grounded by using a rear grounding metal through grounding conductor lines 5a, 5b and via-holes 4; static electricity generated by various treatments during a production process is not concentrated on the conductor metal films 2a, 2b and is discharged to the rear through the grounding conductor lines 5a, 5b and the via-holes 4. When an MIM capacitor is used actually, the grounding conductor lines 5a, 5b are cut at a final stage of the production process.

Title: Seed-box stacker
Inventor: TSURUMI MANABU
IPC: B65G57/00
Filed: 1985-12-06
Abstract: PURPOSE:To prevent malfunctions of switches by disposing switches which are actuated by abutment against the outside walls of a seed-box to generate timing signals for carrying, stopping, pushing-out or the like of the seed-box and providing soil scrapers in the travelling path of the seed box so as to act on the outside of the seed-box. CONSTITUTION:A lift 6 is provided with a soil scraper 61 acting on the outside wall of a lifting seed-box 3 to scrape soil or others adhered to the wall surface. This assures smooth actuation by abutment and pressing with respect to a switch 22 of a conveyer 16 and switches 46, 48, 52, 54 of right and left conveying passages 23, 24, reducing malfunctions due to adhered soil. A soil scraper 62 provided at the start end of the conveyer 16 acts on the bottom surface of the seed-box 3 to eliminate soil or the like adhered to the bottom surface. When moving on rollers of the conveyer 16, a seed-box with soil adhered to the bottom surface would shift the moving direction and could not advance straight, but elimination of the adhered soil assures straight advance, allowing reliable actuation with respect to the switch 22 and smooth operational association with a director 21.
