A polypropylene three-dimensional plexifilamentary fiber having a microwave birefringence of 0.07 or more and an Mw/Mn of 4.3 or less. Although a spreading agent is not included in this fiber, the fiber has a superior fiber spreadability and dimensional stability. The fiber in accordance with the present invention can be spun from a dope composed of an isotactic polypropylene having an Mw/Mn of 4.3 or less and an MFR of 20 or less, and a halogenated hydrocarbon, by a flash spinning technique. Further, the present invention provides a spinning dope and a method of manufacturing the fiber which effectively prevent ozone layer destruction by using a 2,2-dichloro-1,1,1-trifluoroethane, a 1,2-dichlorotrifluoroethane or a solvent blended a dichloromethane with either of the above two solvents as the halogenated hydrocarbon.

A meter module includes a meter panel in which meters and indication lamps are mounted, a centralized control circuit board in which control circuits for car electric devices including the meters and indication lamps are installed, an electric junction box for distribution of power, input and output signals and for integration of earth lines, and a module case. The electric junction box is formed by setting a bus-bar circuit board and an insulator cover in the module case. The centralized control circuit board and the meter panel are fixed over the electric junction box, whereby the meter panel, the centralized control circuit board and the electric junction box are intensively incorporated. The above arrangement simplifies electric wiring in the instrument panel portion of car and facilitates assembling of the electric devices such as the meter panel. A wiring harness protector includes a protector main body for protecting a wiring harness therein and a cover. A plurality of through holes are concentrated in the cover, and a plurality of connectors in the wiring harness set in the protector main body are set through the corresponding through holes in a direction perpendicular to the wiring harness extending direction. The connectors are fixed through a connector stopper to form a multipolar connector. The wiring harness protector simplifies the wiring harness, especially the wiring arrangement of instrument panel harness, and facilitates setting and assembling of wiring harness.

A printer which is compact, can accurately supply paper and has reduced noise characteristics. Additionally, the printer enables easy correction of paper jams and can be selectively operated in various modes according to the user's preference. The printer includes a paper feed roller which is pivotable between a paper feed position and a non-feeding position, a drive force transmitting mechanism for transmitting a drive force to the paper feed roller, a carriage reciprocatively movable along the width of the paper fed by the paper feed roller, and an intermediate transmission mechanism attached to the side of the carriage. Only when the carriage is in a stand-by position, the intermediate transmission mechanism couples with the drive force transmitting mechanism to transmit to the paper feed roller a paper-feed directional rotating force so as to rotate the paper feed roller to the paper feed position. The intermediate transmission mechanism is preferably an idler rotatably mounted on the side of the carriage. The paper feed roller is preferably driven through a planetary gear mechanism including a sun gear provided on a drive shaft, a paper-feed roller holder rotatably mounted on the drive shaft, and a planetary gear coaxially provided with the paper feed roller supported with the paper-feed roller holder.
摘要:
An automatic white balance adjusting method in which color difference signals (E.sub.R -E.sub.Y) and (E.sub.B -E.sub.Y) are respectively integrated on the entire screen and the gains of red and blue signals are controlled such that the average integration values can coincide with predetermined reference levels respectively. In the method, in integrating the color difference signals (E.sub.R -E.sub.Y) and (E.sub.B -E.sub.Y), the integration of the color difference signal that includes a chromatic color is prohibited. Whether or not the color difference signal includes the chromatic color is checked by whether at least one of a plurality of color signals including a color signal (E.sub.R +E.sub.B -2E.sub.Y), obtained by addition of the above-mentioned color difference signals, exceeds its associated one of a plurality of threshold levels which are set correspondingly to the respective color signals.

To effectively form a branch harness from a trunk harness, the wire harness comprises an insulating sheet, a plurality of horizontal harness conductors arranged in parallel to each other on the insulating sheet, and a plurality of second harness conductors also arranged in parallel to each other and perpendicular to said first harness conductors on the insulating sheet. The first and second harness conductors are selectively connected to each other through holes formed in another insulating sheet with soldering, welding, rivets or grommets or by cutting off harness conductor ends along a line inclined at 45 degrees with respect to the harness conductor. Further, it is preferable to directly form male or female connector terminals at each end of the harness conductors.

A composite camera apparatus employing a video camera device, a still camera device and a strobe device. The video camera device includes an electric circuit for picking up video data and processing the video data to record a video signal on a recording medium, such as a video tape. The electric circuit of the video camera apparatus includes means, associated with a strobe device and responsive to initiation of stroboscopic flashing, for controlling the electric circuit for recording the video signal so that a predetermined number of the video data picked-up at the occurrence of stroboscopic flashing, may not be reproduced when the video signal is reproduced by means of a VTR on a video monitor.
