Title: Fitting device of packing for hydraulic cylinder
Inventor: MASUDA BUNJI
IPC: B25B27/14
Filed: 1991-12-17
Abstract: PURPOSE:To perform the fitting work of packing very simply with no fatigue, besides requiring no skilled labor by feeding the packing in lowering it up to the height of an inner circumferential groove in a state of being held between top and bottom of an unfloating shaft and a support shaft, while expansively restoring it with elastic resiliency and then housing it in the inner circumferential groove. CONSTITUTION:In an unfloating state of packing 4 of a packing unfloating shaft 34 by means of a down motion of this unfloating shaft 34, the packing 45 is inflected inward into an elastic recess and formed into almost heart form by a push motion from the side of a packing tip of a first inflection operating piece 62. In addition, it is elastically inflected by the simultaneous advance of a second inflection operating piece 73 and thereby the whole packing 45 is made so as to be housed within the range equivalent to a center hole 21 of an end member (bush) 20. Subsequently, the packing 45 is fed as lowered up to the height of an inner circumferential groove 22 installed in this end member 20 in a state of being held between top and bottom of the packing unfloating shaft 34 and then it is expansively restored in size by means of elastic resiliency, thus it is housed in the inner circumferential groove 22.

Title: Rolling vibration reducing device for engine
Inventor: HIRANO IZUHO
IPC: F16F15/26
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To avoid the engagement failure of the gear of an epicyclic gear mechanism resulted from the deflection change of a crank shaft by fixing a bracket for supporting and fixing the planetary gear of the epicyclic gear mechanism to an engine side member through a vibration isolating material. SOLUTION: A planetary gear carrier 13 is connected and fixed to the inside of a bracket 16 supported on a shaft 15 by a bearing 17. The arm part 16a of the bracket 16 is fixed to a front cover 8 which is an engine side member through a vibration isolating material 22. Although a crank shaft 1 tends to be whirled by the deflection change by combustion pressure or the deflection change in a specified vibration mode, the whirling motion of an internal gear 11 can be absorbed by the elastic deformation of the vibration isolating material 22. Consequently, the engagement failure of the gear of an epicyclic gear mechanism 10 can be avoided, and the rolling vibration reducing effect of an engine body can be improved.

Title: Image forming device
Inventor: OTA YUTAKA
IPC: B65H29/70
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To easily perform a jam process by openably constituting a transportation passage portion receiving straightening from a straightening means. SOLUTION: An interval of a paper transporting passage (sheet transporting passage) formed from a clearance between two facing members, namely a clearance between an inverse guide 1 and a lower guide 15, is maintained by an abut member 20. When a paper jam occurs in a state that a sheet P is transported with being nipped between an inverse roller 9 and an inverse roll 10, it rotates in the G direction around guide pins 17a, 18a provided for side plates 17, 18. Thus, a space C in an inverse transporting passage is released. Therefore, the inverse roller 10 provided for the inverse guide 1 separates from the inverse roller 9. As a result, inverse roller pressure generated by the inverse roller 9 and the inverse roll 10 is eliminated, and the sheet jammed at the place is easily removed.

IPC: E06B7/02
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To improve a function by covering a door end part by projecting a light shielding body having a specific width in a door stop removed part of a door frame by specifying a distance from a surface of a closed door. SOLUTION: A light shielding body T by interposing a prescribed distance S between it and a surface of a closed door 20 is projected at least in a partically removed part of a door stop arranged in a door frame main body 10. Next, the distance S is set to 1 to 20 mm, and a projecting width W of the light shielding body T is set to 5 to 20 mm. Air is always ventilated between the indoor and outdoor sides by forming an air passage between the door 20 and the door frame main body 10 and between the door 20 and the shielding body T at least in a part of the inner peripheral side of the door frame main body 10 when closing the door 20. The light shielding body T also blocks passing of the light between the indoor and outdoor sides by covering a surface end part of the closed door 20.  Therefore, it can be used even in a bedroom since the light does not leak, and adverse influence on the health by an organic solvent in a building material and harmful gas such as smoking can be eliminated since a required ventilation quantity can be secured.

Title: Container preventing poison from being mixed
Inventor: NAKAMATSU YOSHIRO
IPC: B65D8/00
Filed: 1998-11-18
Abstract: PROBLEM TO BE SOLVED: To easily distinguish a container with a poison injected as its appearance has changed to prevent damage before happens by a method wherein the container cannot be patched if it is bored or abnormality which cannot be easily repaired remains on a surface of the container even if it has been patched. SOLUTION: This container preventing a poison from being mixed comprises a can 1 coated 4 with a release agent such as silicone or Teflon on a surface. Thus even if a hole 2 is made and it is to be hidden by applying a patch 3, a can surface can be released from the patch. That is, since a pressure-sensitive adhesive cannot stick to a coating such as silicone or Teflon, the patch cannot be applied but easily releases 5 to have the hole 2 exposed. Further, since content liquid in the can may leak from the hole to contaminate the can or the like, mixture of a poison cannot be concealed to prevent damage. In addition, by coating styrene on the can surface, the hole 2 if bored causes the styrene coating to crack, and since patching the hole 2 cannot conceal the crack, a can with a poison mixed can be found.
