Abstract:
An axial type electronic component inserting apparatus is provided for inserting into holes of a board a pair of lead wires of each of axial type electronic components connected by a tape at regular intervals. A first kind of the components have a larger tape interval and a second kind of the components have a smaller tape interval. The apparatus includes a pair of centering chucks having recesses for contacting both sides of the body of the component, and being movable in a symmetrical manner with respect to the center to adjust the body of the component from both sides of the main body while the recesses come in contact with both sides of the body of the component, thus resulting in centering of the component.
Abstract:
To reliably and simply prevent the output of specified image data, a unit to detect a pattern is installed in one of the devices in a system consisting of an image scanner 1, control device 2 (a personal computer) and printer 3 which are connected consecutively. This pattern detection unit contains a unit which detects a specified pattern from the mass of image data representing a document. Once this pattern has been found, either the subsequent image data are altered before being output or output of the image data is interrupted. When the system starts up, the control unit for each device checks whether that device, or one of the other devices in the system, has a pattern detection unit as described above. If it determines that no device has such a unit, it halts operation.
Abstract:
An automated means for hydrating a molded hydrophilic contact lens is provided in which a first robotic assembly removes a plurality of contact lens molds from a production line carrier, each of the lens molds having a contact lens adhered therein. The first robotic assembly transports the molds to a first staging area where the lens molds are sandwiched between a lens mold carrier and a top chamber plate to form a first hydration carrier. A first rotary transfer device then hands the first hydration carrier to a second robotic assembly which immerses the first hydration carrier in a hydration bath to hydrate the lens and to release the lens from the lens mold. While the lens is immersed in the hydration bath, each lens is transferred from its respective mold to a lens transfer means found within the top chamber plate. After a predetermined period of time, the second robotic assembly removes the first hydration carrier from the hydration bath and hands the hydration carrier off to a second rotary transfer device which rotates the first hydration carrier and aligns it for transfer to a third robotic assembly. The third robotic assembly then carries the top chamber plate and contact lenses through a series of steps in which the lens mold carrier and lens molds are removed from the top chamber plate. The lenses carried on the lens transfer means are then flushed and transported for assembly with a hydration base member to form a second hydration carrier for processing the lens in subsequent extraction stations. The second hydration carrier is then transported through a plurality of flushing or extraction stations wherein fresh deionized water is introduced into the hydration chambers at each hydration station to flush leachable substances from the hydration chamber. At each flushing station, fresh deionized water is introduced into the hydration chamber to remove previously extracted impurities and the products of hydrolysis. A final robotic dis-assembly device separates the top chamber plate and lens transfer means from the hydration base member, to provide fully hydrated lenses in a concave lens holding means ready for transfer to inspection and packaging stations.

Abstract:
A double-picture type television receiver for displaying two different pictures on its screen. The television receiver is equipped with an image memory having a capacity required for storing a child picture signal to be inputted, the child picture signal to be stored being for one picture and a line memory coupled in series to an output of the image memory. Also included are multipliers, one being directly coupled to the output of the image memory for multiplying the output of the image memory by a predetermined coefficient and the other being coupled to outputs of the line memory for multiplying the outputs of the line memory by a predetermined coefficient. An adder calculates the sum of outputs of the multipliers and outputs the sum signal as a child picture signal. A switching device is responsive to a parent picture signal inputted from an external circuit and further to the output of the adder for performing a switching operation between the parent picture signal and the output of the adder with respect to a display device.
Abstract:
A video signal gradation corrector used in a television receiver or the like for preventing the destruction of the gradation of the black side and the floating of the luminance level of the black side and/or an excessive increase of the luminance level of the white side. The corrector can be realized with a small circuit scale. A histogram operating circuit includes an average luminance level detecting circuit. A constant is subtracted from an output signal of the average luminance level detecting circuit by a subtracter. The result of subtraction is multiplied by a constant by a constant-multiplication circuit. A lower-limit limiter circuit limits an output signal of the constant-multiplication circuit to a signal having a value not smaller than 0. An output signal of the lower-limit limiter circuit is provided as an accumulation start luminance level, thereby enabling a gradation correction in which the floating of the luminance level of the black side and the destruction of the gradation of the black side are prevented.
