Filed: 1985-07-17
Abstract: PURPOSE:To prevent completely the troubles caused at an interlocking switch part by providing the 2nd switch means which breaks the contact of the interlocking switch at the power supply side through this power supply side when the interlocking switch opens an energizing circuit. CONSTITUTION:A wiper blade has a reciprocating motion with revolutions of a wiper motor 5. When the motor 5 reaches a prescribed position, a mobile contact 6a of a cam plate 60 is separated from a fixed contact 6c. In this instant, a power supply circuit is broken and the motor 5 is revolved by inertia up to a position, i.e., a stopping position where a mobile contact 6b is connected to the contact 6c and stopped there. While the energization is discontinued to a relay coil 8 as soon as the contact 6a is detached from the contact 6c. Thus, a relay contact 8a is detached from a relay contact 8c and the power supply circuit is cut off to the contact 6a of the plate 60. In such a way, both contacts 6c and 6a are never damaged even in such a case where the motor 5 has reverse revolutions and therefore the contact 6a is connected again to the contact 6c.

Abstract: PURPOSE:To easily obtain a high regenerative output by providing a magnetic head, which impresses a magnetic field to be inverted corresponding to information to a magnetic film in the case of recording and detects the change of magnetic flux outputted from the magnetic film at the time of reproducing, counter to the magnetic film of a magneto-optical recording medium CONSTITUTION:When reproducing information, the irradiation of a laser beam 1 is stopped, and the magnetic flux outputted from a magnetic domain on a magnetic film 4 counter a gap 9 of a magnetic head 6 is guided through a magnetic core 7 to the center of a coil 8. According to the change of this magnetic flux due to the lapse of time, electromotive force to be inverted corresponding to the recorded information is generated at the both ends of the coil 8, and by such a force, the information recorded with high density as the crescent type magnetic domain is reproduced. Thus, since the information is reproduced not by the laser beam but by the magnetic head 6, it is not necessary to set a position between heads for recording and reproducing to require high accuracy especially at the time of high-density recording and reproducing. Thus, the high regenerative output can be easily obtained.

IPC: H04N1/387
Filed: 1994-07-11
Abstract: PURPOSE: To obtain a system and a method for converting color by which a desired gradation and high quality can be secured. CONSTITUTION: A target converted color and a target converting color are selected (inputted). The actual chroma and brightness values of the selected converted color are directly mapped on the chroma and brightness values of the converting color (point C). By using the line (a) connecting the point C and a point indicating the pure gray, namely a first function and the line (b) connecting the point C and a point indicating the pure hue, namely, a second function, the remaining chroma value, namely, the chroma value other than the chroma values of the selected converted color and converting color is mapped. In other words, chroma values smaller than the chroma value (point C) of the selected converted color are mapped by using the first function and chroma values larger than the point C are mapped by using the second function.  The mapping functions can be applied to the mapping of the lightness. Therefore, a desired gradation and high quality can be attained for the finally generated converting color.
