摘要:
A double-side printing apparatus for printing on double surfaces of a recording medium is constructed to prevent both an adverse influence on an image forming unit from a fixing unit and an offset of a toner image on the recording medium. The double-side printing apparatus includes a first image forming unit for forming the toner image on one surface of the recording medium, a second image forming unit, provided downstream of the first image forming unit, for forming a toner image on the other surface of the recording medium, a first fixing unit for fixing the toner image on one surface of the recording medium by a light, a second fixing unit, provided downstream of the first fixing unit, for fixing the toner image on the other surface of the recording medium, and a preventing member, provided between the first fixing unit and the second image forming unit, for preventing the light from the first fixing unit from reaching a photo sensitive body of the second image forming unit. The double-side printing apparatus further includes a guide member for guiding the recording medium, and a charger for charging the recording medium to prevent an offset of an unfixed image to the guide member.
摘要:
Character codes having underline bits are read out of a memory (22). A character generator (18) generates character video signals in the form of horizontal scan lines corresponding to the codes. A line generator (30) generates line video signals corresponding to the underline bits. Where the apparatus is provided in a facsimile transmitter, the codes correspond to an identification of the station or the like and are entered into the memory (22) manually. Where the apparatus is provided in a facsimile receiver, the codes are received by a low speed modem (43) and stored in the memory (22). In either case, the receiver reproduces an original document in response to facsimile video signals with the identification characters, underlined where desired, superimposed on the document pattern.

A sorting member with an optimized surface shape is adopted to pressurize a mixture heated on the sorting member to allow a melted resin mixed in the mixture to adhere to the sorting member to sort the resin from an unmelted resin. Thus, resin materials are sorted and recovered from unwanted home electric appliances and the like at a high purity.

A chip is bonded on a circuit board by aligning in position bumps with board electrodes with interposition of an anisotropic conductive layer between the chip and the circuit board. The anisotropic conductive layer is a mixture of an insulating resin, conductive particles and an inorganic filler. The chip is pressed against the board with a pressure force of not smaller than 20 gf per bump by virtue of a tool, while warp of the chip and the board is connected, the bumps are compressed, and the insulating resin is hardened.

摘要:
A package is formed by covering a circuit board with a thermoplastice film. The cylindrical or sheet-like thermoplastic film is decompressed and used to cover the circuit board to protect the board and components mounted on the board.

An IC chip (2) can be provided to a pre-mount process while being held on a tape-shaped supporting member (5), without being taken out of the tape-shaped supporting member (5).

Within the hermetically sealed interior of a housing 9, a driving bevel gear 15 is fixedly secured to an input shaft 12 coupled via a rotation transmission cable 5 to an output shaft of a drive unit. A spindle 19 rotates jointly and coaxially with the driving bevel gear 15, which meshes with a driven bevel gear 17 coupled in such a manner as to allow a relative displacement in the axial direction. The spindle 19 has an externally threaded portion 19A screwed in an internally threaded portion 20A of a master metal 20. The spindle 19 has one end protruding from the housing 9 to the exterior, the one end being provided with a spindle chuck 21 for retaining a tap T.
摘要:
A printing apparatus for printing on double-sides of a recording medium has a first print control unit for controlling an one-line exposure for the right or reverse side by a horizontal synchronous signal, and a second print control unit for controlling the one-line exposure for the reverse or right side by using this horizontal synchronous signal. A print start timing for the right side can be synchronized with a timing for the reverse side, and is capable of preventing a deviation in print position between the right side and the reverse side of the recording medium even by providing the print control units for the right side and the reverse side, individually.
摘要:
A parts-packaging substrate comprising a metal wiring plate having a mask coated on its surface with several openings. This structure eliminates the need for a thick base formed of an insulating body and a resist layer required in prior art substrates. By bending a terminal of the metal wiring plate to form a connecting terminal, a connector used to connect to another substrate can be eliminated, reducing the cost of manufacture.
