Abstract: A shopping car which can prevent a person walking on a dark road in the night while pulling the shopping car from stumbling by lighting up the step, or can hold an electronic calculator, a folding umbrella, a portable telephone, and the like, surely as required. LED lights (40) connected sequentially by a feeding cord (41) is arranged on the outer surface on the backside of a bag (30) attached removably to the frame (10), a pocket (45) for an electronic calculator is provided on the inside of a lid (32) covering the upper opening, a pocket (46) for a folding umbrella and a pocket (47) for a portable telephone are provided on the left and right side of the bag (30), and an electronic calculator, a folding umbrella, and a portable telephone are held in these pockets (45, 46, 47).

Abstract: A display raster cancellation system using a microprocessor and associated program is disclosed to control moiré pattern appearance on the display's screen. The program of microprocessor (126) controls a signal that is applied to a moiré circuit (130). Input to the microprocessor may be data obtain from the system's video input signal. A synch separator (120) may output horizontal pulses and vertical pulses obtained from the video signal. The following three functions may be performed on the video signal: interlace-progressive (I/P) discrimination (122), scan rate discrimination (124), and vertical resolution discrimination (125). The system may be used for standard television sets, digital television units, computer monitors or other raster display systems. The system may have the I/P, scan rate and vertical resolution input directly to the microprocessor (127) from an external video source via certain control signals.

Abstract: A multi-winding transformer with a short ring includes an electrically conductive discharge path connected to the short ring for discharging the short ring and/or the transformer. Discharging the short ring suppresses or eliminates electrostatic interference caused by the structure and operation of the transformer.

Abstract: A microcomputer for automatically controlling the sound in an audio or audio-visual system. Incoming audio signals from multiple channels are combined and fed to a pair of detector-rectifier circuits. One detector-rectifier circuit is a smoothing circuit with a time constant longer than that of the other detector-rectifier circuit. The signals with a longer time constant are fed to the microprocessor to control the volume function of an audio or audio-visual system. The signals with a shorter time constant are fed to the microprocessor to equalize the source frequency spectrum of an audio or audio-visual system.

Abstract: A circuit for directly differentiating stereo and mono signals regardless of whether a pilot carrier signal is present. The circuit generally includes a detection circuit coupled to a control circuit. The detection circuit subtracts the left and right audio signals, and the control circuit compares the resulting difference to a reference signal. When the reference signal exceeds the difference between the left and right signals, the control circuit judges that the inputs are mono. The circuit is advantageously used to automatically disable a repercussion function of a stereo system when a mono signal is received.
