Abstract: An image forming apparatus includes a paper transport apparatus having a paper supply path, a paper supply tray, and an invert-transport path for alternately transporting blank copy paper sheets and single-face copy paper sheets. The invert-transport path includes an inversion path, a double-face-copy invertor apparatus, and a double-face-copy transport path member. The invert-transport path is connected via the double-face-copy transport path member to the paper supply path, and the paper supply tray is coupled to the double-face-copy transport path member. The single-face copy paper sheets are fed from the paper supply tray via the double-face-copy transport path member to the paper supply path. The paper transport apparatus further includes a control unit for performing a first operation and a second operation.

Abstract: A sheet forwarding apparatus for supporting a sheet on a transfer drum in a electrophotographic copying machine, onto which a toner image on a photoreceptor drum is transferred, which apparatus includes a pressure roller for pressing the sheet onto the transfer drum while forwarding. An arm member supports the pressure roller and is pivotable around a shaft so as to cause the pressure roller to alternately contact and distance from the transfer drum. An oscillating unit is included for oscillating the arm member, and to apply a constant pressure to the sheet through the pressure roller when the pressure roller is in contact with the transfer drum.

Abstract: A sheet registering unit for an image forming apparatus in which in the location upstream of the transfer stage, a preregistering roller device and a registering roller device are disposed while being separated with a predetermined distance from each other, and the leading edge of a sheet of paper is positioned with the aid of a loop of the sheet formed in a manner that the leading edge is thrust against the nip of the paired rollers of the registering roller device, and in this state the sheet is additionally pushed by the preregistering roller pair. In the sheet registering unit, the shafts supporting the roller members of the registering roller device or the roller members are supported by the combination of linear bearing members and springs, and by a pressure in the oblique direction caused in the sheet nipped by the registering roller device, the roller members of the registering roller device are shifted in the axial direction.

Abstract: A paper feeding apparatus for use in an image forming apparatus which transfers a toner image onto a paper, the paper feeding apparatus comprising paper feed device for feeding paper into a paper feed path, a paper sensor device provided adjacent to the paper feed path for detecting paper on the paper feed path to produce a detection information signal, a control device responsive to the detection information signal from the paper sensor device for controlling movement of the paper wherein the paper is fed into an image transfer portion of the image forming apparatus in proper timing with the operation of an image carrying body of the image forming apparatus and wherein the feeding of paper into the image transfer portion is temporarily stopped until the proper timing occurs with the operation of the image carrying body.

Abstract: An aqueous solution comprises lysozyme hydrochloride, dipotassium glycyrrhizinate, at least one selected from the group consisting of sodium chloride, potassium chloride, calcium chloride, magnesium chloride, sodium phosphate, potassium phosphate, sodium citrate, potassium citrate, sodium carbonate and potassium carbonate and water, has a pH of 5 to 9 and is useful for eye drops.

Abstract: A dye mixture and a method of dyeing cellulosic fibers by use of the dye mixture, the dye mixture being capable of dyeing the cellulosic fibers favorably even in the presence of a small amount of an inorganic salt at dyeing, and being composed of a blend of a red water-soluble reactive dye to be represented by the following general formula (I) in the form of free acid, and a specific yellow and/or blue water-soluble reactive dye: ##STR1## (where: each of R.sup.1 and R.sup.2 denotes a hydrogen atom or a lower alkyl group which may contain therein a substituent; R.sup.3 represents a hydrogen atom, a lower alkyl group or a halogen atom and X designates --CH.dbd.CH.sub.2 or --C.sub.2 H.sub.4 OSO.sub.3 H).

Abstract: Disclosed herein is an aqueous solution containing a lipid-soluble active vitamin substance and/or ubiquinone. The solution has a pH of 5.5-8 and additionally contains a hydrogenated lecithin and neutral amino acid. It is stable and free from side effects, and is rather easy to prepare.

Abstract: An aqueous solution containing ubidecarenone which is characterized by the fact that a hydrogenated lecithin is incorporated. This solution is stable and free side effects.

Abstract: A paper guide member adjacent a receptor along a paper transport path is provided with a bifurcation slot having a width greater than the typical width of a stiff paper but narrower than the width of most thinner papers to permit the stiff papers to deform out of the paper transport path upon contacting the receptor.

Abstract: A device for mounting an electronic flash on a camera, which comprises a flat box accommodating film, a substantially pyramidal-shaped projection protruding from the flat box, a lens provided at the end of the projection and a flash receptacle. The device includes a portion for mounting the electronic flash, a portion surrounding and secured to the projection and a hinged portion for removably securing the device to the camera.
