Title: Relief valve structure of oil filter
Inventor: HARA AKIO
IPC: F01M11/10
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To certainly prevent the penetration of a foreign matter and so on into an internal combustion engine, by arranging a relieve bracket having a filtering member at least in its peripheral surface part, on the inner side of the center of the end part of the filter medium of an oil filter, and supporting a relief valve in the inside of the relief bracket through a spring. SOLUTION: In an oil filter in which the end part of an approximately cylindrical filter medium is supported in the bottom part of a cylindrical case through a spring member, a relief bracket 23 arranged on the inner side of the center of the end part of the filter medium is formed, for example, of a metallic mesh member 24, by integrally arranging a cylindrical part 25 and a fixed part 26. Then, for example, two parts of the fixed part 26 which are opposed to each other in a diametral direction, are spot-welded and so on to the valve seat 17 of an end plate 3d, thereby the relief bracket 23 can be fixed on the end plate 3d on the lower side of a filter element. A relief valve is stored and supported by a spring 16 in this relief bracket 23, thus the penetration of a foreign matter and so on into the inside of the relief bracket 23, can be certainly prevented by the mesh member 24.

Title: Ink jet recorder
Inventor: MURAYAMA YASUSHI
IPC: B41J2/01
Filed: 1988-12-30
Abstract: PURPOSE:To obtain high-quality images by providing an ink absorber, a means for bringing the absorber into contact with an ejecting surface of a recording head and separating the absorber from the ejecting surface, a means for squeezing the absorber, a means for preventing color mixing of absorbed inks, a means for preventing the ejecting surface from being dried, and a wiping means for the ejecting surface. CONSTITUTION:A squeezing driving motor 6 is made to serve also as a cap-driving motor, and an electromagnetic clutch is provided for switching between driving of a cap mechanism and driving of a squeezing mechanism. A driving force transmitted by the clutch is transmitted through a gear train 75-78 to a squeezing driving cam 79, the rotation of which is converted into a reciprocating motion of an arm 82. The arm 82 can perform a rectilinear motion along a pin 83 provided on a cap side plate, and the motion is transmitted further through a lever 84 to an ink absorber-squeezing member 5, which deforms an ink absorber 3 by pressing the absorber 3 against an absorber guide 7, whereby an ink is squeezed from the absorber 3 and dropped. The squeezing members for each color are connected by a connecting bar 86, and the driving is transmitted simultaneously for all colors. The driving force of the motor 60 is also transmitted to an arm 92, whereby a blade 88 is rotted on a shaft 94. It is thereby possible to achieve stable ejection of the ink from an ejecting port of a recording head.

Title: Carrier for electrostatic latent image developer, electrostatic latent image developer and image forming method
Inventor: YANAGIDA KAZUHIKO
IPC: G03G9/10
Filed: 1995-12-25
Abstract: PROBLEM TO BE SOLVED: To maintain an adequate electrostatic charge level by specifying the work function of a resin, thereby preventing carrier contamination by a charge control agent and external additives and increasing the rising speed for electrostatic charge even if the charge control agent is not used or even if the amt. of silica, etc., to be added is decreased in spite of the slight use of the agent. SOLUTION: The electrostatic charge image developing carrier prepd. by forming a coating layer contg. conductive fine powder and resin on a core material is formed as the electrostatic charge latent image developing carrier of <=4.5eV in the work function of the resin. The work function of this case is a difference between a Fermi level and vacuum level and is the physical quantity measured by a Kelvin method utilizing a change in vibration capacity on the base of the principle of a contact potential difference. The value of the contact potential difference measured in such a manner is a difference between a reference electrode and the work function and, therefore, the conversion to the work function of the coating layer of the carrier is determined by subtracting the contact potential difference from the work function of the reference electrode.

Title: Manufacture and device of thermoplastic foam
Inventor: JIYAN SHII KOOBU
IPC: B29C48/00
Filed: 1989-12-27
Abstract: PURPOSE: To produce improved rubber-modified foam compositions at lower temperatures without sacrificing throughput rates by melting and mixing a thermoplastic resin, pressurizing the resin melt at a pressure sufficient to permit introduction of a blowing agent, introducing and dispersing the blowing agent substantially throughout the resin melt, and simultaneously cooling and depressurizing it. CONSTITUTION: A melting-mixing mean 10 is adapted to accomplish substantial mixing without sufficient shear to cause a localized temperature rise in the temperature of a resin melt to greater than about 40 deg.C to about 100 deg.C above the glass transition temperature (Tg) or the melt temperature (Tm) of a resin. The pressurized resin melt exiting a pump 12 via an outlet is led through a conduit to the inlet of a pressurized mixing means 13. While the resin melt is fed continuously into the pressurized mixing means through an inlet 15 under the preselected pressure, the blowing agent is continuously injected into the mixing chamber through another inlet 14. The resin gel is discharged under pressure from the pressurized mixing means 13 through outlet 16 and through a conduit to the inlet of the cooling-depressurizing means 19.  The cooled gel exits the cooling-depressurizing means 19 at an outlet and enters the foam-forming die orifice means 20. After the gel leaves the die orifice, the gel is formed into a foam or foamable composition.
