IPC: B32B37/10
Filed: 1997-04-23
Abstract: PROBLEM TO BE SOLVED: To prevent a film from drooping into contact onto a base when pressure fixing with a lamination roll starts after temporarily fitting a tip of the film to the base. SOLUTION: In a film lamination device, after temporarily fitting a tip of a film 20 to a tip of a base 18 with a temporarily fitting component 21, a vacuum bar 22 for adding tensile force by holding by sucking a rear end of the film 20 is driven to a position near the base 18 prior to start of pressure fixing with lamination rolls 14, 16. The film 20 is stretched over between a temporarily fitted point and the suction held point, and prevented from drooping in contact onto the base 18.

Inventor: FUJII TAKASHI
IPC: H01L29/78
Filed: 1994-05-20
Abstract: PURPOSE:To achieve a proper amount of injection of positive holes and a low ON voltage and a small amount of turn-off loss by specifying the total amount of impurity of a collector layer in NPT-type IBGT with a high breakdown voltage. CONSTITUTION:A Gate oxide film 6 is formed on the surface of FZ substrate which becomes n-base layer and then a gate electrode 7 is formed. With the oxide film and the gate electrode as masks, boron is selectively implanted into an n-base layer 3, thus forming a p-base region 4. An n<+>-emitter region 5 is formed by selectively introducing donor-type impurity into one portion of the p-base region 4. Phosphor glass is deposited on the gate electrode 7 as an insulation film 10, an alloy of Al and Si is deposited as an emitter electrode 9 on the surface, and then a p<+>-collector layer 1 is formed on the reverse side by implanting B ion. The total amount of impurity atom of the collector layer 1 is set to 1X10<14>-5X10<15>cm<-2>. Finally, a collector electrode 8 is formed on the surface for completion.

Title: Measurement control of liquid and powder and measurement control instrument
Inventor: HIGUCHI NOBORU
IPC: G05B13/02
Filed: 1987-05-01
Abstract: PURPOSE:To realize a highly accurate and short time measurement and secure a wide measuring range by calculating an output to an operating unit for enabling a flow velocity to change by any of fuzzy control, learning control and optimum control methods from the observation of a deviation between a planned setting value and an actual measured value and the quantity of temporal change in the deviation. CONSTITUTION:A planned setting value is set to a measurement controller 3. A DRV (drain valve) 9 and a CDV (cleaning drain valve) 10 are changed over to a measuring system line to start a measurement. Thus, an SRV (stop valve) 8 is opened by the controller 3, the flow of a material is caused by adjusting the opening of an FCV (opening control valve) 7 and the raw material in a tank 1 is fed to a tank 2. A load cell 4 detects the weight of the raw material and feeds back the value of the weight to the controller 3. The controller 3 calculates a deviation between the actual weight value and a set value from an actual weight value thus obtained and the quantity of temporal change in the deviation. Further, the controller 3 issues a new opening command thus obtained to the FCV 7 by any of fuzzy control, learning control and optimum control systems and changes a flow velocity.

Title: Production of color filter
Inventor: AOYAMA HIROSHI
IPC: G02B5/20
Filed: 1989-04-26
Abstract: PURPOSE:To prevent the polishing of colored layers by the insufficient thickness of an over coat layer by forming the over coat film to >=10mum film thickness. CONSTITUTION:The over coat layer is formed to >=10mum film thickness in the process for producing the color filters by forming the colored layers on a substrate and forming the over coat layer thereon, then flattening the over coat layer and finishing the surface thereof to a specular surface. Such a problem that the polishing of the colored layers results by the insufficient film thickness and which is heretofore not infrequently generated is prevented in this way. Since the upper limit of the film thickness does not exist in principle, there is no need for providing the set value by all means.

Title: Stencil printing device
Inventor: SATO ATSUSHI
IPC: B41L13/04
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To obtain a clear image almost free from density unevenness, setoff and bleeding by reducing the transition amount of ink to a printing paper. SOLUTION: A plate cylinder part, with perforated holes 2a for ink feed on the outer periphery, around which a stencil paper 2 is wound is of a three- tier structure consisting of plate cylinders 6, 7 with formed perforated parts 6a, 7a and an ink diffusion members 5a held between the plate cylinders 6, 7. In addition, the perforated part 6a of the outer plate cylinder 6 is set to a position in which the perforated part 6a is blocked by the non-perforated part 7b of the inner plate cylinder 7. Consequently, a force applied to ink 5 to be pushed out to a printing paper P side from the plate cylinder 6 near the perforated hole 2a of the stencil paper 2, is almost uniform at a part where the perforated hole part 6a is present and at a part where the perforated hole part 6a is not present (non-perforated hole part).  Thus the thickness of an ink layer transferred to the surface of the printing paper P is almost uniform across the entire printing paper P.
