Abstract: PURPOSE:To facilitate processing a sheet in jam attached to a heat roller by providing a separation plate on the entrance side of a recording medium, and disposing the forward end of the separation plate at a close position to a fixing nip part to be close to an outer circumference of the heat roller. CONSTITUTION:A separation plate 40 having an arc-like cross section is disposed between an entrance upper guide plate 35 and a heat roller 30. This separation plate 40 is formed of metal, heat-resistant resin, etc., to be relatively thin. For jamming of a sheet 12 between the heat roller 30 and a pressure roller 31 during fixing an image, an inversible motor is inversely driven to rotate both rollers 30, 31 inversely for returning the jammed sheet 12 to be guided by the entrance upper and lower guide plates 34, 35 through an entrance passage 36 to return to the sheet entrance side. The jammed sheet 12 is then taken out. In this case, when the jammed sheet 12 is attached to the heat roller 30, the sheet 12 is separated by a forward end 40c of the separation plate 40 to be returned to the sheet entrance side.

Filed: 1991-10-14
Abstract: PURPOSE:To safely and effectively perform peeling and shrinking treatment of a fiber structure containing a fibrillated conjugate filament composed of a polyamide component and a polyester component by lightly treating the fiber structure with an alkali and treating in an alcohol-water solution of oxalic acid. CONSTITUTION:A fiber structure such as woven fabric, knit fabric or nonwoven fabric containing a fibrillated conjugate filament composed of a polyamide component (e.g. nylon 6 or nylon 66) and a polyester component (e.g. polyethylene terephthalate) as at least a part of the structure is subjected to slight alkali-thinning treatment to dissolve a part of the polyester component to facilitate the splitting of the conjugate filament. The polyamide component of the treated filament is swollen with a solution produced by dissolving oxalic acid in a mixture of an alcohol and water to achieve the effective peeling and decomposition of the conjugate filament by the process advantageous in view of toxicity and waste water treatment. The obtained fiber structure has voluminousness, softness, feeling to hand, bulkiness and spun-like feeling.

Title: Pcm signal recording and reproducing device
Inventor: DOI TOSHITADA
IPC: G11B27/029
Filed: 1985-12-25
Abstract: PURPOSE:To enable after-recording by converting in series PCM signals of plural channels in which other PCM signals are inserted into an optional channel, supplying them to another magnetic head and recording them again. CONSTITUTION:When, for instance, channels 1...3, 5...8 are recorded, and a channel 4 is empty, after-sound recording of the channel 4 is made. When a connecting switch 5d is turned on, a changeover switch 12d supplies outputs of a series-parallel circuit to the input terminal 13d of a signal arranging circuit 13. Thus, when connection of circuits is made by a group of switches, signals of channels 1...3, 5...8 are read by a magnetic head A or C for reproducing, and then, reproduced channels 1...3, 5...8 are recorded by magnetic heads for recording B and D. At this time, after-sound recording can be made by making recording on the empty channel 4.

Abstract: PROBLEM TO BE SOLVED: To increase the sound-insulative capacity by forming a ventilation part and a non-ventilation part between counterposed surface panels and arranging porous board so as to make a detour of an air passage in the ventilation part. SOLUTION: Air vents 2 of counterposed surface panels 21 are connected by an air passage 20 to form a ventilation part 11 and a porous sound-absorbing material 3 is changed between the panels 21 to form a non-ventilation part 12. In this way, a soundproof door is constituted. In this time, porous boards 1 are arranged so as to make a detour of the air passage 20, between the panels 21 in the ventilation part 11 to lengthen the path of sound waves propagated through the air vent 2 and attenuate the waves and also absorb the sound through the boards 1.  When necessary, a laminated sound-absorbing body 31 that a layer 5 applied with a powdery material is laminated at the outside surface of the sound-absorbing material 3 arranged at both faces of the non-woven cloth 4 is filled in between the panels 21 of the non- ventilation part to absorb sound in the powdery layer 5 and further absorb a part of high frequency sound through the sound-absorbing material 3 and the non-woven cloth 4. In hits way, the sound-insulative capacity can be increased and the detour of the air passage can be easily formed and further, as it is light-weight and thin, the handling property at the execution can be improved.

IPC: B65D51/00
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To put balls into a container from outside, even when it stays uncapped by providing an opening on the cap with a size which the balls can pass through and by inclining the surface of the cap which is adjacent to the opening so that the balls put on them can run into inside the box. SOLUTION: A long slender opening 2 is longitudinally made at the near center of the cap 1. Since this opening 2 is for dropping the balls which are thrown onto the cap 1 into the accommodation box, the width of the opening 2 is formed to a size the balls can pass through there. The cap surface 3 which is adjacent to the opening 2, is inclined so that the balls on the cap surface can run toward the opening 2 via the effect of this inclination. In this case, since the opening 2 is made at the center of the cap, the cap surface 3 which is adjacent to the opening 2 consists of four surfaces, 3a, 3b, 3c, 3d that are all inclined.

Abstract: PURPOSE:To enhance the bonding strength between a metal foil and a fluoric resin impregnated base material, by bonding a material which is obtained by applying a powdery adhesive agent to the metal foil, to the opposite sides of a laminate of several fluoric resin-impregnated base materials, and molding the same while applying heat and pressure thereto. CONSTITUTION:A base material 2 is soaked and impregnated in a dispersion of fluoric resin, dried by an infrared ray and sintered. Several sheets of the fluoric resin- impregnated base materials 2 are then laminated one after another, to the opposite sides of which is bonded a material obtained by applying a metal foil 1 to a powdery substance 3 of fluoric resin. Then, the laminated base material 2 applied with the powdery substance 3 is molded with heat and pressure. As the above powdery substance 3, other than ethylene tetrafluoride.propylene hexafluoride copolymer, ethylene tetrafluoride perfluoroalkylvinyl ether copolymer, fluoric resin may be employed. As described above, since the powdery substance of fluoric resin is employed as an adhesive agent when the fluoric resin-impregnated base material and the metal foil are bonded each other, the contacting area between the metal foil and the fluoric resin is increased thereby enhancing the bonding strength.
