摘要:
Each cooling roll has parallel grooves formed in the peripheral surface thereof so as to extend in a direction which crosses the direction of the roll axis. The grooves on one of the cooling rolls are at a phase difference from the grooves on the other cooling roll. The grooves are arranged at a pitch of 0.05 to 3.0 mm and each of the grooves has a width of 0.01 to 1.0 mm and a depth of 0.03 to 0.5 mm.
摘要:
A method and apparatus for manufacturing a thin amorphous metal strip. Molten metal is injected onto a single cooling roll rotating at high speed. A gas flow impeding wall is disposed adjacent to the surface of a cooling roll and extends across the body of the cooling roll. The wall is located upstream of the molten metal injection nozzle. CO.sub.2 gas is jetted along one surface of the gas insulating wall which faces the molten metal injection nozzle and toward the surface of the cooling roll. An atmosphere rich in CO.sub.2 gas is maintained adjacent the roll surface just upstream of the molten metal injection nozzle.

摘要:
The present invention relates to a connection structure for a printed wiring board to be electrically connected to a FPC. The FPC comprises a long substrate, a plurality of conductors laminated on the surface of the substrate and extending along an axial direction of the substrate. The printed wiring board comprises a planar main wiring board, an insertion opening, and a plurality of the through-hole terminals. Each of the conductors of the FPC abuts the through-hole terminal upon the insertion of the FPC into the insertion opening of the printed wiring board. According to the invention, a connector structure to be connected to FPC is provided inside the printed wiring board in order to mount circuit element in high density, and thus improve degree of freedom in designing wiring pattern.

A thermal transfer type printing apparatus includes a monochromatic printing section and multi-color printing section. The monochromatic printing section includes a thermal head unit for thermally transferring an ink layer of a black ink ribbon onto a paper sheet according to a black image signal. The multi-color printing section includes a thermal head unit for successively transferring cyan, magenta and yellow layers of a multi-color ink ribbon in an overlap state onto the paper sheet according to image signals for the respective colors.
摘要:
A color printing apparatus is provided with a document moving mechanism for reciprocatably moving a color document four times, and a scanner for applying successively white, red, green, and blue lights to the color document during each of the forward movements to produce image signals representative of complementary colors of the color lights. A drum with a paper wound therearound rotates forwardly and reversely in synchronism with the reciprocal movement. At the time of the forward movement of the document and the forward rotation of the drum, the thermal head presses a color ink ribbon against the paper to thermally transfer the ink of the color ink ribbon to the paper. At the time of the reverse rotation of the drum, the thermal head is separated from the drum by means of a solenoid.
摘要:
The present invention relates to a connection structure for a printed wiring board to be electrically connected to a FPC. The FPC has an elongated substrate, and plural conductors are laminated on a surface of the substrate for extending along an axial direction of the substrate. The printed wiring board has an insertion opening provided at an edge surface for being inserted by a top end portion of the FPC, and plural line connecting terminals formed on an internal wall surface of the insertion opening. The top end portion of the FPC has a slider including plural elastic deformable first contacts, and a first housing for holding the plurality of contacts. The FPC is inserted into the insertion opening of the printed wiring board such that one end of the first contact presses the conductor and the other end of the first contact presses the line connecting terminal. The FPC can be connected to the printed wiring board on an edge surface thereof, allowing circuit elements to be mounted in high density, and improving freedom in designing wiring patterns.
摘要:
A connector comprises a housing and a cover housing. The housing has a recess formed for insertion of a FPC. The housing comprises a first contact, a second contact and a third contact. The first contact and the second contact includes a first arm, a second arm, and a horizontal leg. The third contact includes a fixing arm, an elastic arm opposing the fixing arm, and a connection leg connecting said fixing arm with said elastic arm. A cam is arranged between the elastic arm of the third contact and the bottom surface of the recess of the housing for locking at a tip of the elastic arm.

摘要:
An electrical connector for connection of a flat-type connection member is disclosed. The electrical connector comprises a cover adapted to be pivotally moved for opening or closing an opening of a housing. A first and a second contact are retained by the housing in a manner to face into the opening. The first and second contacts are press-inserted from a rear side of the housing into corresponding fixing holes so as to be fixed therein. The first and second contacts each include a lead exposed from the rear side of the housing. The leads of the first and second contacts are arranged in a zigzag fashion as alternately shifted forwardly and rearwardly relative to each other.
