Title: Magnetic tape recording and/or reproducing apparatus with recorded channel indicator
Inventor: OGURO MASAKI
IPC: G11B33/10
Filed: 1986-06-03
Granted: 1993-05-25
Abstract: ABSTRACT OF THE DISCLOSURE          A  recording  and/or  reproducing  apparatus selectively   performs   video   recording   and   audio recording  on  a common magnetic  tape.    In  an  audio recording mode, the video recording area used to record video signals in a video recording mode is divided into a  plurality  of  segments  serving  as  audio  recording channels.   The recording and/or reproducing apparatus is provided with a recorded channel detector and an indicator including a plurality of indicator segments, each  of  which  corresponds  to  one  audio  recording channel.    The  detector  produces  a  detector  signal representing   that   the   current  channel   is  pre-recorded.  The indicator segments are responsive to the detector signals from the recorded channel detector to turn  ON  to  indicate  that  the  corresponding  audio recording  channel  is  occupied.    This  arrangement facilitates channel selection for the audio recorder by simply monitoring the indicator.   In order to detect pre-recorded channels, it is most convenient to scan a pilot  signal  superimposed  on  the  audio  signal  and recorded on the corresponding channel.  Therefore, the recorded channel detector can scan the tape and produce detector signals by referring to the pilot signal.

Abstract: HITCH Abstract of the Disclosure A tractor has a typical three-point hitch with lower lift arms and an upper stabilizing arm comprising, in part, of a transverse horizontal rod extending between the lift arms.  A pair of connecting structures are mounted on the implement and spaced on the order of the lift arms but being transversely offset therefrom.  Each of the connecting structures includes a vertical plate having a U-shaped edge opening vertically for receiving the transverse bar.  A link is mounted on the fore-and-aft plate and extends from one position in which it traverses the opening of the U so as to retain the bar in the nip area of the U-shaped edge and a position in which it extends vertically and opens up the U-shaped edge so that the bar may have ingress and egress from the nip area.  A latching rod extends from the plate and there is provided an opening in the link that receives the latching rod.  The link is mounted on the plate so that it may yield transversely to bypass the latching rod and is biased to lie alongside the plate and to be locked by the latching rod in its first position.

Granted: 1991-07-09
Abstract: ABSTRACT OF THE DISCLOSURE           A peristaltic pump  for pumping  fluids  through  a flexible tube  is described which has a quick release and engagement mechanism that permits easy and rapid removal or insertion of the flexible tube into the device.  The quick release and engagement mechanism of the invention consists of a shoe mounted for vertical displacement on the body of the pump.  Upward movement of the shoe engages the flexible tube holding the fluid to be pumped and locks the tube against the roller assembly containing an eccentrically mounted roller which intermittently engages the tube and forces fluid out of it.  To disengage the flexible tube from the pump, the shoe is moved downward out of contact with the flexible tube.
