Abstract: ABSTRACT OF THE DISCLOSURE         A miniature helical scan video tape recorder (VTR) utilizes a reduced-diameter guide drum, but the video signals recorded thereby onto the tape have a standard track pattern and can be reproduced using a standard VTR having a guide drum of standard diameter D1.  In the miniature VTR, the tape is wrapped for a tape wrap angle .alpha. (e.g., substantially 300 degrees) at a still angle .THETA.2, whereas the standard VTR uses a wrap angle of 180° and a still angle of .THETA.1.   In order to ensure that the miniature VTR achieves the same record track length ?'N and recording angle .THETA.0 as the standard VTR, the diameter D2 of the miniature VTR is selected to satisfy the equation  ; where fV is the video field frequency.  The still angle .THETA.2 satisfies the equation       , and the video signal to be recorded is given a non-standard horizontal scanning frequency f'H according to the relation   , where fH is the standard horizontal scanning frequency.  The recording head can be provided with two gaps for double-azimuth recording of the video signal.

Abstract: ABSTRACT:         A method of manufacturing a field effect device, the source and drain zones of which (15,16) have exten-sions (12,13) of an accurately and reproducibly determined length adjoining the gate electrode (4A).  According to the invention, on a first silicon layer (4), from which the gate electrode is to be formed, there is provided an oxidation-preventing layer (5) and thereon a second sili-con layer (6).  A part of the second silicon layer (6) is removed, the edges of which part substantially coincide with those of the gate electrode to be formed.  The edges (8) of the remaining part of the second silicon layer are oxidized.  Through successive maskless selective etching steps, the first silicon layer (4) is exposed and etched away at the area of the oxidized edge portions (8). through the openings (11) thus obtained, the extensions of the source and drain zones (12,13) are implanted.

Abstract: ABSTRACT A lug loader for loading individual boards of lumber from a feed transfer to a lugged transfer in a lumber mill.  A plurality of saw-toothed wheels engage each board in turn and propels it onto the lugged transfer.  A plurality of parallel stop members receive boards individually from the feed transfer, each stop member having a board-receiving portion to receive and support a board lying transversely across the stop members and a stop portion preventing further travel of said board when resting upon the stop members.  The stop members are movable between raised and lowered positions and are located relative to the saw wheels such that a board lying across the stop members is maintained out of engagement with the saw wheels in their raised positions and may be lowered into engagement with the saw wheels.  The presence or absence of a board on the stop members is detected and a control signal is generated in accordance with the condition detected.  A lug index associated with the lugged transfer generates a control signal at predetermined points of progression of the lugged transfer whereat a lug is at a position to receive a board from the feed transfer.  The control signals are applied to a controller which actuates the stop members such that when the lugged chain transfer is at an appropriate point to receive the board and the presence of the board on the stop members is verified, the signals applied to the controller causes the stop members to move to their lowered position and when it is detected that the board has been propelled forward by the saw wheels, the stop members are returned to their raised position to receive the next board.  The combination of the positive saw wheel drive for the boards and the board detecting means eliminates many problems associated with conventional "backlog-fed" devices.
