Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a waterproof sheet for roof underlayment which is excellent in nail hole water shutoff properties, highly strong and abundant in flexibility and is given slip-proof properties and cushioning properties. SOLUTION: Due to the elasticity of a film 2 of a thickness 50-200 μm which is used for an intermediate layer and contains polyolefin resin having a modulus of repulsion elasticity of 15% or above, nail hole water shutoff properties are excellent, and since fibrous nonwoven fabric 3 is laminated on the rear side, this sheet comes into close and flexible contact with a sheathing roof board so that it lies along this board, and has slip-proof properties, in combination with cushioning properties, in relation to the sheathing roof board. Since drawn threads 4 of synthetic resin are arranged and laminated on the surface side, moreover, the mechanical strength of the sheet is increased and also an effect of slip resistance in the case when a worker gets on the sheet is given.

Title: High-gain amplifier
Inventor: NAKATANI TAKAYUKI
IPC: H03F3/34
Filed: 1986-10-31
Abstract: PURPOSE:To keep the load resistance value at a constant level despite fluctuation of the collector potential of an emitter-earthed transistor, by inserting a base-earthed transistor in series between an amplifying active element and an active load containing a constant current circuit. CONSTITUTION:The current Iref outputted from an active load 3 is divided into a current ie flowing to a base-earthed transistor TR5 and a current id flowing to an active element 7 via a level shifter 6. The sum of both currents ie and id is always kept at a constant level. While the base current ib of an amplifying active element 5 and the current flowing through the element 7 flow to a constant current circuit 8. The circuit 8 functions to keep the sum currents (ib+id) at a fixed level. As a result, the resistance value is very large when the load side is viewed from the element 1 and also kept at the constant level. Thus a high-gain state is surely maintained with a high-gain amplifier.

Title: Base paper for thermal stencil printing
Inventor: KAWAZU YUKIO
IPC: B41N1/24
Filed: 1999-09-16
Abstract: PROBLEM TO BE SOLVED: To print a beautiful image from a first sheet even by printing by a high resolution type printer without changing a density of an image even by printing in a large quantity, by setting a pressure loss of the air in a porous support to a specific value. SOLUTION: In a porous support, a pressure loss of an inner air is set to less than 5 mmAg, preferably 4 mmAg or less or more preferalby 3 mmAg or less. If the loss of the air is 5 mmAg or more, a permeation resistance of an ink is increased. When printed by a high resolution type printer, a density of an image at initial several sheets becomes insufficient, and stable printed product cannot be obtained. A method for setting the resistance of the air to less than 5 mmAg includes the steps of mixing fibers of two or more types having different fiber diameters, regulating a crest amount or regulating a pressing pressure after papermaking.
