IPC: C08L67/02
Filed: 1990-10-29
Abstract: PURPOSE:To obtain the above biaxially oriented film for a magnetic recording medium superior in sliding properties and further wear resistance, by a method wherein the title film is obtained by mixing a specific quantity of thermoplastic polyester resin and polyamide resin containing a mxylylene group. CONSTITUTION:This biaxially oriented film for a magnetic recording medium is a resin mixture obtained by mixing up 90-99.99 pts.wt. thermoplastic polyester resin and 10-0.01 pts.wt. polyamide resin containing a mxylylene group with each other. This biaxially oriented film for a magnetic recording medium possesses structure where the polyamide resin containing the mxylylene group is dispersed by forming a fine phase, that is, a particulate in thermoplastic polyester. Therefore, though the surface of the film is smooth, it has fine unevenness and is superior in sliding properties. Furthermore, since affinity between the thernoplastic polyester resin and polyamide resin containing mxylylene is favorable, a void is hard to generate on the circumference of the particulate and the film is superior in wear resistance.

Title: Structure for regulating amount by which high-pressure fuel injection device is lifted
Inventor: YOSHIDA TAKEO
IPC: F02M47/00
Filed: 1989-11-09
Abstract: PURPOSE:To enhance the accuracy of actuation of a high-pressure fuel injection device by causing the rear end face of an injection valve body to abut on the opposite face of a back pressure chamber directly or via a shim member so as to regulate the amount by which the valve body is lifted, and forming in the upper face of the shim member or the rear end face of the injection valve body a recessed portion into which hydraulic pressure is introduced. CONSTITUTION:When an injection solenoid coil is turned on a switching valve body 15 is lifted and a small hole 3c is opened and the pressure within a back pressure chamber 3b is lowered and an injection valve body 6 is lifted so that fuel is injected. When the injection solenoid coil is turned off a nozzle is closed. The amount by which the valve body 6 is lifted is regulated by the space between the upper face of a shim plate 28 and that face 3f of the back pressure chamber 3b which is opposite to the upper face, and, in the case of the amount being large, back pressure does not immediately act on the whole area of the upper end face 6h at the start of the closing movement of the valve body 6 when the upper end face 6h makes sealing contact with the shim plate 28 and the opposite face 28b, but because a hydraulic pressure introduction space is formed between the recessed portion 28b of the shim plate 28 and the upper end face 6h, the back pressure surely acts on the recessed portion 28b and the start of the closing movement of the valve body would not be delayed; the accuracy of actuation of the high-pressure fuel injection device is thereby enhanced.

Title: Internal filtering device
Inventor: KATO YUKIO
IPC: A01K63/04
Filed: 1990-10-31
Abstract: PURPOSE:To remarkably reduce the accumulation of sludge by providing a bottom plate in internal filtering device communicated with the passage holes of the inner partitioning plate in respective rooms and a passage space along the bottom plate between bottom surface of the filter member, thereby prohibiting proliferating configuration of bacteria to be as a filter film type. CONSTITUTION:In the filter medium room (b) flowing-in water from passage hole 6 of inner partitioning plates 3 becomes a forced stream along the bottom plate 4. When the filter member layers are present thereon, bacterias are made to flow out by the dynamic pressure of the stream and lose its functions, thus, an adverse effect by stream is not caused by changing the stream into the bottom passage. The stream is abutted on the wall face 18 and stirred and buffered and made to flow to the passage hole 6' of inner partitioning plate 3, cause rising stream in space layers 8-8'' by the pushing back condition and meanwhile penetrated and dispersed into the filter member 16 and cleaned by the contact with bacteria. In this exemplified case, excelsior type filter member having large passage space is used, so these actions are surely executed. Since the utilization of filter medium having large passage space, partial passage of water is prevented by the buffering action of the bottom passage so convenience utilizing only merits of the filtration medium is obtained.
