Abstract: A breather device of a vehicle engine is arranged so as to shut off an engine intake system from heat of an engine exhaust system and to make effective use of dead space for location. The breather device includes a breather tank arranged independently between the engine intake system and the engine exhaust system on the rear side of a cylinder assembly of the engine above a crankcase thereof; and a plurality of breather pipes connecting the breather tank to the engine and the engine intake system.

Abstract: An apparatus for measuring the life time of minority carriers includes a light source for irradiating a first region of a semiconductor wafer, a microwave generator for generating microwaves, a transmission line for transmitting a first part of the generated mark raised to the region of the semiconductor wafer that is radiated by the excitation light and a second portion of the generated microwave to a region of the semiconductor wafer that is not radiated by the excitation light. The intensity of the microwave signals reflected from the semiconductor wafer are detected and the life time of the minority carriers is calculated based upon the detected intensities.

Abstract: A charged particle accelerator capable of accelerating arbitrarily charged particles to an arbitrary energy level and resonating at a low frequency suitable for accelerating heavy ions, including quadruple electrodes which are supplied with high frequency power and disposed in the direction of the center axis of a cylinder-shaped container and a resonant circuit having a capacitor and an inductor for supplying a voltage to the quadruple electrodes. The capacitor is composed of a plurality of metallic plates provided along the center axis at specified intervals in the vicinity of the quadruple electrodes, and a plurality of conductive supports supporting the metallic plates which are directly connected to the container together with the supports and the container form the inductor.

Abstract: An apparatus for detecting position/variance of input light is disclosed which includes a photoelectric conversion device receiving input light constituted of a first resistive layer formed of a first photoelectric conversion material and a second resistive layer formed of a second photoelectric conversion material connected with the first resistive layer through a depletion layer or directly, wherein the first resistive layer is provided with uniform resistivity throughout its surface so that a linear output proportional to the average of the distances between one end of the photoelectric conversion device and positions of the input light is detected and the second resistive layer is provided with resistivity dependent upon the distance from its one end so that a quandratic ouput proportional to the average of the squares of the distances between one end of the photoelectric conversion device and positions of the input light is detected.

Abstract: A method an apparatus for measuring the distance to a target wherein FM wave is transmitted to the target and its reflected wave is received. A beat wave is then obtained using the thus-received wave and the FM wave. A sine wave is mixed with the beat wave and a first sideband wave of a plurality of sideband waves of the resultant mixed wave is obtained. Another sine wave is mixed with the sideband wave. Then, a second sideband wave of the thus-obtained mixed wave is separated and detected. In the above manner, phase modulation is applied directly to the above-described beat wave. Information pertaining to distance can then be obtained from the number of peaks of the thus-modulated beat wave. A microwave profile meter suitable for use in the determination of the surface profile of a burden in a blast furnace is also disclosed.
