Title: Fuel feed system for plurality of cylinders internal combustion engine and control device thereof
Inventor: NAGANO MASAMI
IPC: F02M69/04
Filed: 1989-06-19
Abstract: PURPOSE:To modify an exhaust gas component produced during a time between the low temperature starting and warming up of an engine by a method wherein the fuel injection timings of a plurality of cylinders are moved from the exhaust stroke side to the suction stroke side of each cylinder of an engine in response to an engine running temperature selected from an engine running state. CONSTITUTION:In a device in which the opening time and the opening timing of a fuel injection valve 23 disposed in the vicinity of the suction port of each cylinder are controlled by a control unit 25 based on an engine running state, during the starting of an engine when a cooling water temperature detected by a water temperature sensor 29 is a low temperature, for example, -30 deg.C, the injection timing of each fuel injection valve 23 is set to the suction stoke side of each cylinder. When a cooling water temperature is increased to, for example, 0 deg.C with the progress of running of an engine, an injection timing is gradually transferred from the suction stroke side to the exhaust stroke side. Further, when a cooling water temperature is increased to, for example, 60 deg.C, the injection timing is transferred to the exhaust stroke side, and control is effected so that, in a normal running state (a water temperature of approximate 80 deg.C), the injection timing is restored to an ordinary value.

Title: Method and apparatus for polishing surface of lens
Inventor: HAWAADO JIEIMUZU BAANETSUTO
IPC: B29D11/02
Filed: 1982-09-07
Abstract: arious forms of multifocal contact lenses can be produced having improved properties. The surface of a lens (1) to be polished is brought into contact with a polishing compound (19) associated with a flexible (but non-resilient) sheet (18), causing the sheet (18) to flex. Fluid pressure is applied to the sheet counteracting the flexing as a result of lens contact, so that polishing compound associated with the sheet makes contact with the lens surface with uniform force distribution. Relative rotation between the lens (1) and sheet (18) is effected so that all portions of the lens surface in contact with the polishing compound are polished to the same extent. The lens is then ground to provide a multifocal lens. A hydrophilic or silicone multifocal contact lens having desired distance and intermediate powers may be constructed by acting on the lens (2) so that it is capable of accepting grinding activity, and the grinding it without distorting it. The lens (2) may be backed by a chuck (34) or hard lens (3), or frozen, and ground by grinding apparatus (60) while backed or frozen.

Title: Forming method for ceramic formed body
Inventor: TAGUCHI MICHIO
IPC: B01J4/00
Filed: 1992-06-15
Abstract: PURPOSE:To provide a method, with which a tree-dimensionally shaped formed body different in thickness in extrusion direction can be formed, the degreasing and drying of the formed body can be performed in a comparatively short period of time and, at the same time, the highly densely packed body is formed with no surface defect. CONSTITUTION:Mixed material 4 under the predetermined mixing ratio is prepared. Under the condition that a mold 6 is rotated about the extrusion direction of the mixed material 4, the mixed material 4 is extruded in a three-dimensionally-shaped cavity so as to fill the mixed material 4 in the cavity 6 and, at the same time, shape the mixed material 4 by the cavity 6a by the pressure at the extrusion. Ceramic powder is kept under clay-like condition, which is suitable for filling in the three-dimensionally shaped cavity 6a and, at the same time, shaping by the same cavity 6 by the pressure at the extrusion, by being turned into the mixed material 4 under the above-mentioned mixing ratio. Further, since the fluidity of the mixed material becomes larger in nearly proportional to the shearing force applied to the mixed material through the rotation of the mold 6, the mixed material ideally flows in the cavity 6a by the pressure at extrusion. Furthermore, no much organic binder is employed as compared with the binder employed in injection molding method.
