Title: Tuning voltage display device for a color television receiver with an electronic tuner
Inventor: KAMIYA MASANORI
IPC: H04N5/50
Filed: 1979-03-15
Granted: 1982-04-01
Abstract: The display device uses a diode to control an associated primary color output TR(transistor) so that a specific color is intensely reproduced.  A diode is associated with each of 3 primary color outputs TRs(81,82,83) which provide an output for switching in accordance with received bands of TV signals.  These associated switches are provided between the electronic tuner(3,4) and the power source for the circuitry.  The diode associated with each primary color output TR is on-off controlled by a pulse so a predetermined pluse width is generated following the termination of a period responsive to the magnitude of the tuning voltage.

Title: Means for pulling tape from reel
Inventor: HERITRICH FRIEDRICH R
IPC: G11B15/00
Filed: 1985-06-12
Granted: 1993-06-22
Abstract: The present arrangement includes a first tape leader (11) which can be readily and automatically coupled to a second tape leader (23). In a preferred embodiment the first tape leader is connected to be wound on a take up reel while the second tape leader is connected to a tape to be pulled from a supply reel. The first tape leader (11) has one end formed into a mushroom like tab (13) with a supporting stem (17). The second tape leader (23) has a locking aperture (21) at one end thereof which is proportioned so that a wide section thereof can fit over said mushroom like tab (13) while a narrow section thereof will accept the stem (17) but block passage of the mushroom tab (13) therethrough. Accordingly when the tab (13) is passed through the wide section and the leader (11) is moved (pulled) toward the narrow section of the locking aperture (21), the tab (13) and part of the stem (17) become locked in the narrow section. Hence the leaders are locked, or, buckled, to enable the first tape leader (11) to pull the second leader (23). The first and second tape leaders each have a smoothing aperture (25), (33) therein which provides a means to accept the bumps created by buckling the tab (13) into the locking aperture (21) so that the wrapped around leaders are in a smooth configuration when pulling a tape.
