Abstract: A driving mechanism for driving an electrophotographic photosensitive body operates through a torque limiter. The torque limiter is arranged on a support shaft for supporting the photosensitive body. A driving gear for driving a developing member is arranged coaxially with the torque limiter independently of the latter. This arrangement reduces the load applied to the torque limiter. In addition, the mechanism remains compact.

Abstract: A laminated glass structure comprises two glass sheets, a plastic layer arranged at the bonding surface of one of the glass sheets, and a functioning layer consisting of single- or multi-layered films provided on the bonding surface of the glass sheet to the plastic layer, wherein the functioning layer has a film having an energy gap of 4 electron volts or higher which is in contact with the plastic layer.

Abstract: A magnetic recording medium comprising a magnetic recording layer and at least one protective layer formed on the recording layer, wherein the outermost protective layer on the side exposed to air is made of an oxide film.

Abstract: An original scanning apparatus comrpises a scanning unit for scanning an original. The scanning unit has a mirror and a light source for illuminating the original. A connecting member is electrically connected to the scanning unit. A guide member supports and guides one end of the scanning unit. The guide member fixes a position of the one end of the scanning unit in a vertical direction. At least a part of a driving element is disposed at the position overlapping with the guide member in the vertical direction, but not overlapping with the mirror of the scanning unit. The connecting member is provided at the side of the guide member.

Abstract: A window glass has a heat ray reflective layer including metal nitrides as a component thereof and an antenna conductor for an automobile wherein the heat ray reflective layer has a surface resistance of at least 20 k.OMEGA./sq. for preventing interference with the antenna operation.

Abstract: The present invention relates to an image forming apparatus in which a sheet cassette for containing sheets is removably mounted to a body of the apparatus. The image forming apparatus comprises a frame structure having a pair of legs spaced apart from each other, a bottom plate arranged on the legs, a first side plate arranged at one ends of the legs and uprightly mounted on the bottom plate, a second side plate arranged in confronting relation to the first side plate at the other ends of the legs and having a lower end portion extending below the legs and covering the other ends of the legs, and stay members for interconnecting the first and second side plates at their upper portions.

Abstract: A sheet feeding device for use in an image forming apparatus provided with a sheet support plate and one or more rotary members for separating and feeding sheets. A recessed portion is formed on the sheet support plate in a position opposing to each rotary member. A detachable auxiliary member is provided to be fitted in the recess to form a plane coplanar with that of the sheet support plate. An engaging device can be provided, to engage with a step portion formed in a cassette housing portion of the apparatus to keep the cassette from being entirely removed from the housing. The engaging device may, for example, include an elastic part and an engaging part integrally molded with each other.

Abstract: A waste gas purification apparatus having an elongated vertical hollow furnace shaft adapted to receive pebbles therein with a waste gas inlet at the lower end with a pebble discharge means at said lower end. At the top of the shaft is a narrow exhaust gas duct with a pebble feed chute, a pebble charge device and a pebble recirculating tube extending from the discharge hoppers to the charge device. A blower is coupled to the gas inlet for force feeding waste gas through said gas inlet. At the upper end of the shaft is an inactive travel zone. Between the inactive travel zone and the lower shaft is an intermediate shaft with a temperature control chamber in parallel with said intermediate shaft. Pebbles move downwards in the shaft from the inactive travel zone to the discharge hoppers and are recirculated to the upper end while waste gas is fed to the lower end and travels up through the shaft, a portion of the gas passing through the temperature control chamber, the clean gas leaving the upper end.
