Abstract:
An optical scanning device includes a light source, an optical system, and a housing. The light source projects a light beam. The housing includes a holder and encloses the optical system. The optical system includes a liquid crystal element held by the housing via the holder, to modulate a phase of the light beam projected from the light source against a scanned surface. The liquid crystal element includes a plurality of substantially transparent substrates, a liquid crystal layer, and a sealing member. One of the plurality of the transparent substrates has a size larger than any other transparent substrates and is positioned in the holder. The liquid crystal layer is sandwiched between the plurality of substantially transparent substrates. The sealing member seals the liquid crystal layer between the plurality of substantially transparent substrates.
Abstract:
A contact image sensor is provided including a housing, a slit plate a lens, one or two light sources and a light-receiving element array mounted on a light-receiving element array substrate. The housing contains the slit plate, the lens, the one or two light sources and the light-receiving element array substrate. The optical system of the contact image sensor is aligned and one or more depressions are formed on an end of the substrate for the alignment. Power to the one or two light sources is applied through one or more leads. Each of the one or more depressions is large enough so that each of the leads can be passed through the respective depressions.
Abstract:
An optical scanning apparatus constructed to dispose optical elements guiding light beams to a deflector such as a rotary polygon mirror at a low cost with high accuracy, includes a first light source, a second light source, a deflector, a first optical member provided on a first optical path between the first light source and the deflector, a second optical member provided on a second optical path between the second light source and the deflector, and one wall holding both of a side surface of the first optical member and a side surface of the second optical member.
Abstract:
A semiconductor device includes a semiconductor chip with a functional surface, a substrate opposing the functional surface of the semiconductor chip at a space formed between the substrate and the functional surface, a power supplying device electrically connected to a part of the functional surface of the semiconductor chip and separated by a slight gap from the substrate, a fixing member that fixes the semiconductor chip to the substrate, and a sealing member that seals the space formed between the substrate and the functional surface of the semiconductor chip other than a space formed between the substrate and the functional surface of the semiconductor chip that are fixed to each other through the fixing member and other than the gap formed between the power supplying device and the substrate. The sealing member has greater elasticity than the fixing member.

Abstract:
The invention relates to a joining construction for mounting the CCD cells of a color line camera on a color splitting prism (30) attached to a prism housing (2). Each CCD cell (6, 7, 8) is attached, by a first glue joint (13), to its fastening element (9), the length (L2) whereof is essentially larger than the length (L1) of the CCD cell, and which fastening element (9) extends from the housing margin (12a) located on one side of said exit surface (20a, 20b, 20c) of the color splitting prism to the other housing margin (12b) located on the opposite side thereof. Each fastening element (9) is attached to said margins by third glue joints (11).
