Abstract: A multi-stage motor-driven fuel pump including a motor section provided with an electric motor and a pump section to be driven by the electric motor, the pump section having a plurality of pump chambers partitioned by intermediate plates and communicated with each other by a fuel communication hole formed through each of the intermediate plates. A ratio of a sectional area of the fuel communication hole of any one of the intermediate plates between adjacent ones of the pump chambers to a sectional area of the pump chamber on a lower pressure side is set in a predetermined range such that a gradient of fuel pressure increase in the pump section is increased to early prevent vapor lock.

Abstract: A fuel injection controlling device for a two-cycle engine includes an electronic fuel injection system having a fuel injection quantity determining device for determining a fuel injection amount in response to rotational speed and throttle opening of the engine. At engine start, the controlling device, in response to operation of an engine kick starter, sequentially decreases starting fuel amount as the number of actuations of the kick starter increases. Fuel injection amount is also decreased in response to increasing engine temperature.

Abstract: There is described a composite sheet includes a textile layer containing an electrically conductive fiber with an electric resistance of 10.sup.5 to 10.sup.9 ohms/cm as disposed at spaced intervals not exceeding 30 mm and a semiconductive layer with a surface resistivity of 10.sup.6 to 10.sup.10 ohms as disposed on the reverse side of the textile layer. This composite sheet releases the static electricity of the charged body on mutual contact and is therefore suitable for use as a car upholstery material and particularly as a seat covering material.

Abstract: There is disclosed an air cleaner of an engine for a vehicle. The air cleaner shaped by fitting upper and lower cases together includes an air intake unit inclined downwards so that a cylindrical part, provided at the top end of the air intake unit, for joining an air valve is disposed in a relatively lower position than the air intake unit. During a process of airtightly fitting the upper and lower cases, this arrangement restrains an engine overall height to a low value and prevents fluctuations in sectional area of the air intake unit which are due to reconstruction of the air intake unit to eliminate the difficulty caused particularly in a portion for joining the air valve to the air intake unit.

Abstract: A control method for a valve-timing changeover in an engine having a valve operating mechanism capable of operating the intake valves or exhaust valves, or both, in a different manner, known as valve timing, such as the magnitude of valve lift or the duration the valve remains open, for improving the operation of the engine at different engine speeds. The control method uses various parameters to cause the changeover to occur when the engine output is substantially the same in the two different valve timing speed ranges between which the changeover is being made to minimize any shock loading during the changeover. In a fuel injection type engine, the preset quantities of fuel injection that would normally be supplied to the engine for those two different valve timing speed ranges are used to determine the engine output and return the proper time for the changeover.

Abstract: An image processing apparatus furnished with an overhead projector has an image projecting function and an image-forming function. The image processing apparatus is designed to detect the movement of an original support table or a reflection-type focusing plate during projecting of an original. The result is that the original support table is free from being heated by the focusing plate and also that the focusing plate is free from any deviation of its axis of light, thus preventing the reflected light from striking on the eyes of the operator.

Abstract: Apparatus is provided for controlling the size of the image plane in a camera having a zoom lens. The apparatus includes one or more aperture frames (31, 32, 120) which define the image plane size, and an actuator which is adapted to move the aperture frame or frames along the film plane in accordance with the optical position of the exit pupil of a zoom lens. Two frames can be moved in opposite directions over an equal displacement. Further, a single frame (120) can be moved along the optical lens axis in order to ensure that the film remains substantially flat during photography, and is moved away from the film path during film winding and unwinding operations. Additionally, the frame can be provided with projecting portions along opposite side edges of a central aperture in order to control the image plane size.

Abstract: A recording apparatus including an apparatus body having a front section on the operator's side and a rear section remote from the operator's side, a medium feeding device supported by the apparatus body, for feeding a substantially transparent recording medium along a predetermined feed path defining a boundary between the front and rear sections, such that one of opposite surfaces of the medium faces the operator's side, a recording device disposed in the rear section of the apparatus body, for recording an image on the other surface of the medium, and a control device for controlling the recording device such that the image is laterally reversed as viewed in a first direction from the recording device toward the above-indicated other surface of the medium, with respect to a nominal desired image as viewed in a second direction from the front section toward the one surface of the medium, whereby the laterally reversed image is seen as the nominal desired image when viewed in the second direction.

Abstract: A machine tool with a spindle for machining a large-diameter workpiece in that a servo motor for moving a spindle in the axial direction and a variable reluctance motor for rotating the spindle are installed in a housing, and a synchronous controller for synchronizing and driving the above-mentioned servo motor and the variable reluctance motor is provided. The variable reluctance motor has a characteristic in that a large driving torque can be obtained in a low rotating speed. By using a variable reluctance motor as a spindle motor, therefore, it is possible to obtain a large torque without providing a large size motor, and also possible to realize a large-diameter machining by a small-size unit.

Abstract: A keyboard is hinged at the front end of the main body of an electronic apparatus. The keyboard swings around the hinge section to have a folding position in which it is raised upright against the front face of the main body and an operating position in which it is laid down in a virtually horizontal attitude. The keyboard incorporates a key switch circuit board on which a matrix of electrical contacts is formed, and the main body incorporates a main controller board for the electrical apparatus. A connecting printed circuit board is used to connect the signal lines of the key switch circuit board to the corresponding signal lines of the main controller board. The connecting printed circuit board is flexible, and is bent when the keyboard takes one of the folding position and operating position. Its bend is relaxed when the keyboard takes the other position.

Abstract: A method wherein, when a multi-injection molded body made of at least a first and a second resins is molded, catching means are formed generally by pressing a part of the surface about an opening of a concave section formed in a first molded body made of the first resin to project interior side wall faces of the concave section inward, and injecting a second resin to mold a second molded body in the concave section. The multi-injection molded body thus formed has catching means in the concave section, so that the second molded body is tightly fixed to the first molded body.

Hence, the size and weight of the intake manifold and/or the exhaust manifold can be reduced.
