Abstract: A semiconductor device for absorbing a noise comprises a first (12) and second (14) buffer. The first and second buffers receive an external signal (S) having a rising edge and a falling edge, and performs waveform shaping thereof to produce an output signal. The first buffer (12), which issues an output signal (Sa) for controlling the internal circuits of a chip of the semiconducteur device so as to make the chip's internal circuits active/stand-by, is not sensitive to the rising edge of the external signal (S), but is sensitive to the falling edge of the same external signal. The second buffer (14), which issues an output signal (Sb) for controlling an output circuit of a chip of the semiconductor device so as to make the output circuit active/stand-by, is sensistive to both the rising and the falling edges of the external signal.

Abstract: The device has a transfer cylinder (2) with a drum (4) which is adjustable in the circumferential direction relative to its shaft (3) and which carries sheet grippers (8) with a front stop (8a) for the sheets (B). The diameter of the transfer drum (2) is equal to 1/N of the diameter of the plate cylinder which carries N printing plates. The shaft (3) of the transfer cylinder (2) rotates at a constant speed and executes N revolutions when the plate cylinder is executing one revolution. By means of a controllable setting device, the drum (4) is so displaced relative to the shaft (3) during each revolution that the front stop (8a), when its transfer position in which a sheet is transferred to the impression cylinder (D) is passed, assumes a position by which the exact register of this sheet in relation to the position of the printing plate printing it on the plate cylinder is set. This guarantees that the width of the front margin between the sheet front edge and print start is of the same size on all the printed sheets, without the need to adjust the printing plates exactly on the plate cylinder in a time-consuming way.

Abstract: Apparatus for use with a printer which has a pair of tractors that engage sprocket holes in the paper to adjust for different paper widths or to adjust the lateral position of the paper. The apparatus comprises a pair of coaxial lead screws (25, 26) one (25) attached to a rotatable shaft (29) and the second (26) rotatable on the shaft (29) adjacent to and relative to the one lead screw (25). One tractor is coupled to each lead screw (25, 26). Rotation of the one lead screw (26) is obtained by a knob (30) keyed to an end of the rotatable shaft (29). Rotation of the second lead screw (26) is prevented during rotation of the knob (30) by spring loaded fingers (31a) with detent elements engageable with detention gearing (26c) on the end of the second lead screw (26). Rotation of both screws (25, 26) is obtained by rotation and axial movement of the knob (30) on the shaft so that a cam surface on the knob engages cam means of the spring fingers (31a) to disengage detent elements from the detention gearing and drive gearing on the knob (30) engages drive gearing on the second lead screw (26).

Abstract: The present invention relates to the identification and purification of a herpes protease and a nucleic acid segment coding for two proteins. The first protein is the herpes protease which is able to cleave itself and also cleave the second protein. This protease is required for the assembly of the herpes virus capsid, therefore is essential for replication. The second protein has previously been designated as the family of proteins in viral infected cells, ICP35. The protease and its substrates are encoded by overlapping nucleic acid segments. This invention also relates to a promoter sequence for the second protein. Methods are presented of producing a viral protease, screening a protease inhibitor which may be used in a drug designed for the treatment of herpes disease, methods for treating herpes and other viral infections wherein the virus employs a protease substantially similar to the herpes protease, for capsid production. Methods for detecting herpes infections and other viral infections are also disclosed.
