An electrode bonding method according to the present invention includes: a plasma cleaning step of irradiating an electrode surface to be cleaned of at least either one of a part, such as a semiconductor device, and a substrate with atmospheric pressure plasma for cleaning; an inert gas atmosphere maintaining step of covering the electrode surface to be cleaned and its vicinity with a first inert gas before the irradiation of the atmospheric pressure plasma is ended, and maintaining that state even thereafter; and a bonding step of bonding an electrode of the part and an electrode on the substrate before the inert gas atmosphere maintaining step is ended. The electrode surface is thereby plasma-cleaned without the possibility of damaging the part to be bonded to the substrate, and the cleaned state is maintained while bonding the electrodes to provide an electrode bonding state of high bonding force and high reliability.

A method for manufacturing a heat resistant flexible laminate effectively enabling avoidance of not only visual defects but occurrence of dimensional changes, and a heat resistant flexible laminate are provided. In a process for laminating a heat resistant adhesive material and a metallic foil by thermal lamination, a film-like protective material is disposed between a pressurized surface and the metallic foil at the time of thermal lamination. At this time, coefficients of linear expansion in a temperature range of 200 degree C. to 300 degree C. of the heat resistant adhesive material and the protective material are within a range of a coefficient of linear expansion of the metallic foil ±10 ppm/degrees C. Thereby, occurrence of visual defects is not only effectively avoidable, but excellent dimensional change after etching may be exhibited.

An image forming apparatus including plural image forming units arranged for respective color components at predetermined intervals. A transportation unit transports a recording medium to the plural image forming units. A delay memory delays sending of image data for a time required to transport the recording medium between the plural image forming units. A length holding unit stores, for each page, plural pixel counts, the pixel counts representing respective numbers of pixels in rows of pixels spaced in the sub-scan directions, which pixels represent the image data for image formation. A reading control unit controls reading of the image data stored in the delay memory on the basis of the pixel counts of each page stored in the length holding unit.

A transmitter 1 transmits from a transmission antenna 7 a mixture signal containing a radio-frequency (RF)-band modulated signal, and a portion of power of a local oscillation signal used for frequency conversion. Meanwhile, a receiver 8 detects the transmitted signal by means of a reception antenna-detection section 9. In the reception antenna-detection section 9, a plurality of base unit reception circuits 11 are disposed. Each base unit reception circuit 11 includes a planar printed antenna 12 such as a patch antenna, an amplifier circuit 13 formed on a very small planar circuit by means of an MMIC technique, and a mixer circuit 14 serving as a square-law detector. Respective outputs of the base unit reception circuits 11 are power-mixed and fed to the IF signal demodulation section. The IF signal demodulation section 10 demodulate reception data. This configuration enables realization of a reception antenna which occupies a very small space, has a detection function and a high gain, and has a wide beam characteristic comparable to that of a single-element antenna.
