Title: Sound volume control circuit
Inventor: SAITO MASAMI
IPC: H04N5/445
Filed: 1987-04-27
Abstract: PURPOSE:To eliminate the disadvantage such as remaining sound by generating another analog DC voltage corresponding to a sound volume control pulse, monitoring it by a switching means and making the characteristic curve steep at a low sound volume thereby decreasing forcibly the sound volume control voltage. CONSTITUTION:When the pulse width PW of the sound volume control pulse VP is comparatively wide, since a DC voltage ce' is low, a transistor (TR) 66 is turned off. When the pulse width PW of the sound volume control pulse VP is narrower than a prescribed value, the DC voltage ce' is increased more than the prescribed value and the TR 66 is switched to the on-state (conductive state). When the TR 66 is turned on, part of the electric charge to be charged in the capacitor 28 goes to earth through a resistor 68 and the sound volume control voltage CE is decreased by the value. Thus, the sound control characteristic curve L2 which is smooth at the middle and high sound volume regions and steep suddenly at low sound volume region is obtained and the sound remaining at the lower sound volume region is avoided while the smooth on- screen display control is ensured at the middle and high sound volume regions.

Abstract: PROBLEM TO BE SOLVED: To establish a system with which highly precise inspection of a high quality surface having tiny defects can be carried out by installing a phase plate in a region near the optical axis of laser light beam and where the intensity of the beam is almost zero and making delay. SOLUTION: Beams, for example laser beams, emitted by a coherent light source 12 are filtered by a spatial filter/beam expander 13 to have their axes parallel and pass through and proceed toward a phase plate 16. The phase plate 16 introduces phase delay in a region near the optical axis and where the intensity of the beam is almost zero. Qualified light beam is continuously transmitted while the phase information being buried in the beam structure. When the beam position is controlled along scanning beam by installing a servomechanism 17, the y-coordinate of an object 24 to be processed is moved and the scanning servo is sent to a computer 19 and a signal with which wide scanning can be carried out is generated. In the case the object 24 to be processed is mounted on a frame/servomechanism 28, the x-coordinate of two-dimensional scanning is obtained by the movement.

Abstract: PURPOSE:To prevent the damage to a tape at the time of tape unloading by providing a tape tension control means to suppress the increase of contact force between the tape and a tape guide means in a process that the tape guide means is moved between a first position and a second position. CONSTITUTION:Until a first detection signal is obtained after the start of unloading, the take-up torque of reel motors 4 and 5 is increased in the shape of a step or in a linear shape. Until a second detection signal is obtained after the first detection signal, the take-up torque of the reel motors 4 and 5 is fixed and until a third detection signal is obtained after the second detection signal, the take-up torque of the reel motors 4 and 5 is decreased in the shape of the step or in the linear shape. In such a manner, the increase of tape tension is suppressed during unloading. Thus, the tape damage such as the insertion of a tape 18 between a tape guide end part and a guide roller 7, etc., can be suppressed.
