Title: Delivery valve abnormality detecting device for fuel injection pump
Inventor: GOTO KEIZO
IPC: F02D45/00
Filed: 1990-08-28
Abstract: PURPOSE:To detect the abnormality of a delivery valve accurately during operation by detecting fuel oil pressure in a fuel injection pipe, and judging differential pressure between the residual pressure immediately before fuel injection and the lowest pressure generated immediately after fuel injection on the basis of the detected result. CONSTITUTION:When the fuel injection of a fuel injection valve is terminated, oil remaining in a fuel pipe 10 is closed in by a delivery valve 27 on the fuel pump 20 side and by a needle valve on the fuel injection valve side so as to hold the fixed residual pressure. Immediately after the termination of injection, this residual pressure is fluctuated because of pressure fluctuation caused by in-pipe reflected waves, secondary injection, and the like, but becomes nearly the fixed pressure P1 by the time immediately before the following fuel injection. On the other hand, the in-pipe lowest pressure Pmin becomes nearly the fixed value (around zero) immediately after the termination of injection regardless of the residual pressure P1. If the abnormality is generated in the delivery valve 27 at this time causing defective operation, the residual pressure P1 is lowered although no change is generated in the pressure Pmin. The abnormality of the delivery valve 27 can be thereby detected by a computer 103 by monitoring the differential pressure  P between P1 and Pmin by a pressure sensor 100.

IPC: H04N9/31
Filed: 1984-10-25
Abstract: PURPOSE:To obtain a compact projector free of image distortion and color aberration and capable of adjusting the size of the picture and white balance by providing the polarizing plates that pass polarized lights of various colors and plural means to respectively detect lights of different colors that pass the areas other than those corresponding to the screens of transmitting liquid crystal. CONSTITUTION:A dichroic mirror 9 that reflects blue lights and transmits yellow lights is used. The blue lights along the X-axis reflected by the dichroic mirror 9 is reflected by a mirror 10, and then pass through a liquid crystal 11 controlled by the signals B from a controller 25 and are polarized. By impressing voltages corresponding to the signals B to the transparent electrodes of different picture elements, the polarization axis of the incident lights is controlled. The luminance signals corresponding to the luminance aberration which are successively derived from the photoelectric element in accordance with the picture scan, controls through an amplifier 37 the gains of AC drive amplifiers 30, 31, and 32. Thus, the luminance aberration of the picture is corrected.

Title: Sound absorbing material
Inventor: TAKAGAKI MITSUTOSHI
IPC: B32B5/18
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To eliminate a foamed film and to impart good water barrier properties to a sound absorbing material by using a first nonwoven fabric having a larger apparent density than that of a second nonwoven fabric layer, and forming a structure in which a foamed resin region formed by foaming foamable resin composition from the first layer side. SOLUTION: The sound absorbing material comprises a structure in which a second nonwoven fabric 2 having a smaller apparent density than that of a first nonwoven fabric layer 1 is integrated on the layer 1. And, the absorbing material of the layer 1 side comprises a structure in which a foamed resin region X formed by foaming impregnated foamable resin composition is formed. Here, as the apparent density of the layer 1, if it is excessively small, its surface protrusions and recesses or voids are increased. Hence, open cell foams are easily formed in the foam resin composition X. As a result, its water barrier properties are lowered. Reversely, if the apparent density is excessively large, the resin composition sufficient to realize the water barrier properties is scarcely impregnated.

Title: Sealing sack for nonaqueous electrolyte battery
Inventor: HOSOKAWA TAKEHIRO
IPC: H01M2/02
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a sealing sack capable of sufficiently preventing production of fluoric acids. SOLUTION: This sealing sack for a nonaqueous electrolyte battery seals a nonaqueous electrolyte constituting a nonaqueous electrolyte battery and is formed out of a sheet material having at least two metal layers 22a and 22b between plastic layers 24 and 28. According to this structure, pinholes existing in the two metal layers 22a and 22b do not overlap substantially. Even if non-aqueous electrolytic solution is encapsulated in the sack, it is possible to sufficiently prevent production of fluoric acids originating from externally water infiltration. Because water intrusion from outside the sack can be prevented satisfactorily even if pinholes exist, the thickness of the metal layers 22 can be lessened sufficiently.

Filed: 1987-09-10
Abstract: PURPOSE:To easily mold an item with a complicated shape in a short time without developing the clogging of resin by a method wherein a material mixing device is provided at the outlet of a port to feed material to a mold and the mold is hermetically closed and at the same time a vacuumizing device to evacuate the interior of the mold is connected to the mold. CONSTITUTION:Resin, which is fed in a cylinder 13, is passed through a flow path 13-1 and fed from a material feeding outlet 13a at the tip part of the cylinder 13 to a mold 19. On the other hand, polymerizing agent is passed through a flow path 13-2 and fed from material feeding outlet 13b at the tip part of the cylinder 13 to the mold 19. The air in the mold 19 is withdrawn in advance by means of a vacuum pump. In addition, the resin and the polymerizing agent are mixed with each other by means of a mixing blade 11 when they are fed from the material feeding outlets 13a and 13b in the mold 19 and, after that, fed in the mold 19, which is held under vacuum. As a result, since no air mixed in molding material, a highly accurate molded item can be produced. Further, since no resin fixes to the material feeding outlets 13a and 13b and the like, every time when one molding cycle comes to an end, the mold 19 can be removed from the tip part of the cylinder and a new mold can be attached for next molding, resulting in allowing to efficiently perform a highly accurate molding.

Title: Surface treated steel sheet having superior rust resistance and its production
Inventor: EZURE KAZUYA
IPC: C25D5/12
Filed: 1986-09-26
Abstract: PURPOSE:To produce a steel sheet having superior rust resistance in the naked state and superior workability such as weldability by a small extent of coating by successively coating the surface of a steel sheet with specified amounts of Zn and Ni in layers by a specified total amount. CONSTITUTION:When the surface of a steel sheet is successively plated with Zn and Ni in layers, the amount of Zn is made <=2 times the amount of Ni and the total amount of Zn and Ni is regulated to <=10g/m<2>. In case where the amount of Zn is >2 times the amount of Ni, the rust resistance of the resulting plated steel sheet in the naked state is deteriorated and the adhesion of the layers to the Fe base is not satisfactory during working such as deep drawing. In case where the total amount of Zn and Ni is increased to >10g/m<2> per one side, the effect is not further enhanced and the cost is increased. The rust resistance of the plated steel sheet in the naked state can be especially improved by partially alloying the Zn and Ni layers by heat treatment at >=150 deg.C.
