Abstract: A motorcycle being assembled on an assembly line is transferred from a first line to a second line by gripping and lifting a front wheel of the motorcycle up to a prescribed height to support the motorcycle only through a rear wheel thereof, moving the motorcycle from the first line to the second line while rolling the rear wheel, clamping the rear wheel, and thereafter lowering the front wheel to move the motorcycle along the second line. The motorcycle can automatically be transferred reliably and efficiently, and various motorcycles of different types can easily be transferred by a single apparatus by only gripping front wheels thereof.

Abstract: An automobile antenna control device generating a reset pulse which starts the operation of a microcomputer. The pulse is generated when an automobile radio power source is switched from "off" to "on," or when the power source is switched from "on" to "off," so that a so-called runaway of the microcomputer can be prevented. The power source is connected to an input port of the microcomputer; the antenna is extended when the power source is "on," and is retracted when the power source is "off." The extending or retracting action of the antenna is stopped when the starter power source of the master key switch of the automobile is "on.

Thus, the reliability of the system is improved and the installing and the servicing of the system is simplified.

Abstract: A method for preventing loosening of a bolt fastened to a metallic member coated with an anticorrosive paint film without removing the paint film. Anticorrosive painting is applied on a metallic member, and then the painted film is thinned by applying an urging pressure onto a bolt seat surface portion of the painted metallic member by means of a press rod. The bolt seat surface portion of the metallic member also may be flattened by applying an urging pressure on the bolt seat surface portion by means of a press rod or by machining the bolt seat surface portion before the anticorrosive painting is applied on the metallic member, and then the painted film is thinned by applying an urging pressure onto the above-mentioned bolt seat surface portion by means of a press rod.

Abstract: The present invention provides methods to take advantage of the exhaust gas pulses in an exhaust system of a multi-cylinder internal combustion engine to increase the volumetric efficiency over the complete operating range of the engine. It solves the problems of other systems which are only able to gain a beneficial effect from the exhaust gas pulses over a limited range of the engine operating speeds, by providing a means of varying the exhaust pipe lengths, combinations, and cross-sectional area of the exhaust passages of the multi-cylinder internal combustion engine. By this means it provides an exhaust system in which the exhaust gas pulse frequencies can be varied over the entire operating range of the engine to obtain desirable pulse frequencies matching the cylinder exhaust timing for efficient extraction of the exhaust gases, improvement in volumetric efficiency and a higher maximum engine speed.

Abstract: An exposure device for an image exposure onto a photosensitive recording medium includes a cathode ray tube serving as an exposure light source which supplies an optical radiant energy onto the recording medium. The photosensitive recording medium has an .gamma. characteristic in a relation between the density of the image recorded thereon and an optical radiant energy applied thereto. For recording an image corresponding in density to an image of an original, there is provided a driver circuit which receives an input voltage indicative of the density of the image on the original and when the input voltage exceeds a predetermined value, an output voltage applied to the cathode ray tube to cause an image of 0% (white) in density to be recorded on the recording medium. When the input voltage is below the predetermined value, the output voltage is applied thereto which changes in proportion to the input voltage.

Abstract: A power steering system for use in a motor vehicle is disclosed.

Abstract: A motorcycle has a head pipe, a pair of laterally spaced main frames extending rearwardly from the head pipe, and a receptacle supported on the main frames. In order to effectively utilize a space between the main frames, the receptacle has a bottom wall positioned between the main frames, the bottom wall having at least a portion positioned below a plane including an upper surface of the main frames.

Abstract: An automatic fuel boosting system for supplying an optimum amount of fuel to an internal combustion engine based on engine temperature. This fuel boosting system includes a sensor for sensing if the engine temperature at the time of starting is below a predetermined value, an advance angle control circuit, responsive to the sensor, for advancing the ignition angle based on engine temperature, and a solenoid, responsive to the control circuit, for actuating a fuel boosting device so that an optimum amount of fuel is supplied to the intake manifold of the engine based on engine temperature, if the engine temperature is sensed to be below the predetermined value.

Abstract: A power transmission system transmits rotative power from a driver pulley to a driven pulley through a toothed belt. The tooth tips (27b) and/or tooth bottoms (27c) of teeth of at least the driven pulley (10) lie in a plane including a central axis l.sub.2 of rotation of the driven pulley and are inclined with respect to the central axis l.sub.2. When the toothed belt (14) is operated to transmit the rotative power, the position where teeth of the pulley (10) and teeth of the toothed belt (14) start meshing with each other is progressively displaced, thus lowering the level of impact sounds produced when the teeth mesh with each other.

The endless belt has feed pins provided projectingly in a row at equal intervals on an outer peripheral face thereof, and a paper holder provided on the cover is positioned, on at least one side of the feed pins, in parallel to the outer peripheral face of the endless belt.

Abstract: Primary and secondary coils are wound on a differential type magnetic head, and a low frequency signal is applied on the primary coil. Based on the difference between the output voltages from the head when an object of detection is placed near the magnetic head on the detection side and the output voltage therefrom when an object is not placed near the magnetic head, the magnetization characteristic curve of the magnetic flux and the magnetic field is calculated. Since the magnetization characteristic detection is determined by dividing a magnetic flux by the measured area cross section, once the magnetic flux is determined, a general B-H curve can be simply calculated. The magnetization characteristic measurement device includes a differential type magnetic head portion having plural differential type magnetic heads in linear arrangement which is positioned on or near the magnetic thin film of a detection object.
