Abstract: An inking device for feeding ink that is fed to an ink rail to a printing plate on a plate cylinder via a group of rollers that are sequentially in contact with each other, comprising a first roller part of the outer periphery of which faces an ink feeding surface of the ink rail, a second roller that is disposed downstream of the first roller in the ink feeding process and in contact with the outer periphery of the first roller on the downstream side in the rotating direction from the position at which the first roller faces the ink feeding surface of the ink rail, a third roller that is in contact with the first roller on the downstream side in the rotating direction from the position at which the second roller comes in contact with the outer periphery of the first roller, and a fourth roller that is in contact with the outer peripheries of the second and third rollers and blocks the front side in the rotating direction of the first and second rollers at the position where the first and second rollers are i

Abstract: A container including a tube member having a truck portion which is elastically squeezable, and a wide-mouthed neck portion extending upwardly from the trunk portion, a top wall closing a top surface of the neck portion and having a discharge port, said top wall also having a peripheral portion connected to a top end of the neck portion, from which the peripheral portion is made undetachably, and a cover plate connected by a hinge to the neck portion and having a plug for closing the discharge port, the plug depending from an underside of the cover plate, wherein the top wall has a first breaking line which is formed within the peripheral portion of the top wall, and a knob for tearing the first breaking line, said knob is formed on the top wall within the first breaking line.

Abstract: A microwave signal amplifier comprising transistor having input and output terminals further includes input and output matching circuits connected to the input and output terminals, respectively, and corresponding bias supply circuits connected in parallel between said transistor and said input and output matching circuits, respectively. The input and output matching circuits are each implemented by high pass filters, and the bias supply circuits are each implemented by low pass filters. Furthermore, said high pass and low pass filters respectively have capacitors and inductors connected to the transistor, and said low pass filters have termination resistors.
