摘要： Automatic clutch control to reduce shocks to a vehicle during a rapid switching of a shift lever between its drive D and reverse R positions. The shift lever position and the direction of movement of the vehicle are detected by means of a switch and an electrical circuit. A microprocessor delays the initiation of the clutch engagement by a given time as compared with the clutch engagement occurring when the vehicle is at rest, if the shift lever position is in contra-distinction to the direction of movement of the vehicle, namely, when the shift lever is in its drive D position while the vehicle is moving backward or when the shift lever is in its reverse R position while the vehicle is moving forward.

摘要： A planar inverted F antenna with stable radiation characteristics, which is not vulnerable to ambient influence, having, an insulator, a radiation device formed on one surface of the insulator and a grounding plate formed on the other surface thereof. A coaxial cable has a central conductor electrically connected to the radiation device and an outer conductor electrically connected to the grounding plate at two points spaced from each other by approximately a quarter of the wavelength of current flowing through the outer conductor. If leakage current flows along the outer conductor, the leakage current is negated by an inverse-phase current flowing through the grounding plate.

摘要： A magneto-optical converter utilizing the Faraday effect is disposed between the opposed ends of an iron core having a magnetic field extending therebetween. The magneto-optical converter is comprised of a body of material exhibiting the Faraday effect which is provided with a light receiving surface and a light exiting surface. A polarizer in the form of a polarizing beam splitter is located adjacent the light receiving surface whereby an incident beam of light perpendicular to the magnetic field will be deflected and polarized at right angles to the incident beam of light and directed into the receiving surface of the body of material. An analyzer comprised of a polarizing beam splitter is located adjacent the light exiting surface whereby the beam of light from the body of material will be deflected and polarized and exit the analyzer at right angles to the magnetic field. The receiving and exiting surfaces of the body material may be bevelled and optical rotators may be disposed intermediate the bevelled surfaces and the polarizer and the analyzer respectively.

摘要： A high-pressure vessel is allowed to be in an initial state, and a first chamber is disposed downward. Copper or copper alloy is placed in the first chamber, and SiC is set in a second chamber. The high-pressure vessel is tightly sealed, and then the inside of the high-pressure vessel is subjected to vacuum suction through a suction pipe. An electric power is applied to a heater to heat and melt the copper or copper alloy in the first chamber. At a stage at which the molten copper in the first chamber arrives at a predetermined temperature, the high-pressure vessel is inverted by 180 degrees to give a state in which SiC is immersed in the molten copper. An impregnating gas is introduced into the high-pressure vessel through a gas inlet pipe to apply a pressure to the inside of the high-pressure vessel. Thus, SiC is impregnated with the molten copper. The high-pressure vessel is inverted by 180 degrees, and then the impregnating gas in the high-pressure vessel is discharged through a gas outlet pipe, simultaneously with which a cooling gas is introduced into the high-pressure vessel through the gas inlet pipe to cool the high-pressure vessel.
