A device for electrically interconnecting and packaging electronic components and method for manufacturing the device. Specifically, in a frame, wire grid polarization elements are aligned and light shielding members are provided on end portions of the polarization elements. The seat rail provides support for a bicycle seat and provides means for securing the seat to the frame of a bicycle. 5 to 20% by weight of an oil-based additive; and from 0. The driver circuit is configured to change at least one of the value of the first voltage and the value of the second voltage so that a voltage difference between the first and second voltages becomes large when the power loss of the switching elements is estimated to exceed a certain value. An image forming method is also disclosed, comprising exposing the photothermographic material to light using a light source having emission within the wavelength region of 350 to 450 nm.
