IPC: B41F31/20
Filed: 1987-03-09
Abstract: PURPOSE:To facilitate screwing of a screw even when a fixed screw is tightened, by placing a fine regulating device for a doctor blade contacting pressure between the head portion of the fixed screw and the plane of a doctor blade holding member through a belleville spring, thereby avoiding fluctuation of doctor blade contacting pressure due to loosening of the fixed screw. CONSTITUTION:When the contacting pressure of a wiping roller 26 with a type area is regulated, a fixed nut 34a is loosened to cause rotary operation of a handle 33. Consequently, a threaded shaft 34 advances/retracts through screw function so as to advance/retract a hydraulic cylinder 37 coupled to the threaded shaft 34 through a coupling 36 thus rotating an eccentric bearing 25 slightly. When the scratching operation of a blade 45 is regulated, a handle 55 is grasped and an adjusting screw 54 is rotated, then a blade holder 43 advances or retracts so as to regulate contacting pressure of the blade 45 which is integrated with the blade holder 43. Since the blade base 41 is simply urged by spring force of a belleville spring 48, the blade 45 can be adjusted with the fixed screw 44 being tightened.

Abstract: PROBLEM TO BE SOLVED: To reduce base resistance by forming a base electrode, composed of a low-resistance conductive layer made of metal, a silicide of metal or the like, on the surface of a base region in a self-aligning manner. SOLUTION: A base electrode 8a and a collector electrode 8b are formed by selectively evaporating a metal layer only on the surfaces of an external base region 7 and a collector lead-out region 6 through selective CVD, wherein types of gas and substrate temperature are set as required, in such a manner that the base region 7 and the collector lead-out region 6 will be exposed on the surface of a substrate. As the result of this selective CVD, the base electrode 8a and the collector electrode 8b are formed in the external base region 7 and the collector lead-out region 6 by self-alignment. Any metal, as long as it can be selectively grown on silicon, may be used for the metal layer that forms electrodes; a metal with lower contact resistance is better. This makes it possible to reduce the total base resistance of bipolar transistors to a small value.
