Abstract: An actuator unit 100 which moves a light reflection element 32 in a predetermined optical path-switching-position includes a mover 120 to which the light reflection element 32 is fixed, and a fixed part body 110 including an E-shaped yoke 113. When the mover 120 is located at one end in its moving range, the posture of the mover 120 is specified by magnetic attraction forces in two directions orthogonal to each other which are generated between one end portion 113a yoke 113 and an orthogonal part 113c of the E-shaped, and the mover by a permanent magnet 121 and an electromagnet 118, whereby a tilt of the mover 120 can be prevented.

Abstract: The invention is to offer an optical device which is capable of reducing the insertion loss comparing with a conventional one. The optical switch comprises a fiber collimator for input an light beam, a fiber collimator for output the light beam to the outside, an optical path switching element, an optical path switching element as well as a slider arranged in the optical paths between the fiber collimator and the fiber collimator to change the light path and the optical characteristics, a solenoid actuator for moving the slider, a guide mechanism for guiding the slider as the slider moves, a magnet for generating a magnetic field, the magnet being arranged at a position where the slider is pressed against the guide mechanism by means of a magnetic force of a magnetic field generated by the magnet.

Abstract: The disclosed herein is a novel and less expensive optical path switching apparatus for switching at least one input optical path selectively into at least one output optical path which comprises; switching means for switching the input optical path selectively into the output optical path which has at least one switching optical path to permit a light beam to pass thereon, inputting means for inputting at least one light beam to the switching means, and outputting means for outputting at least one light beam from the switching means, the switching means being essentially consisting of (i) a housing, (ii) at least one switching element having a first reflection surface to reflect the light beam inputted from each of input optical paths and a second reflection surface to reflect the light beam reflected from the first reflection surface toward the output optical path of the outputting means, and a reflection space formed between the first and second reflection surfaces of a switching element body, and (iii) at

Abstract: A vehicle air conditioning system has an interior unit in which a width dimension, that is, a dimension parallel to the width of the vehicle, is smaller than competing devices. A blower unit, an evaporator as a cooling heat exchanger, and a heater core as a heating heat exchanger are integrally disposed inside a casing for blowing air toward a vehicle compartment. A face passage is formed above the heater core such that the temperature-controlled air passes through the heater core and is lead to a face opening by the face passage. A foot passage is formed inside the casing and above the heater core so as to protrude from the rear face of the casing toward the face passage. A foot door for opening and closing a foot opening of the foot passage is disposed inside the face passage.

Abstract: A magnetic recording and/or reproducing apparatus and methods thereof for a composite color TV (television) signal arranged such that a luminance signal and a high band component of a chrominance subcarrier signal of the composite color TV signal are frequency modulated, recorded and reproduced, while a low band component of the chrominance subcarrier signal is frequency down converted to a frequency at a band lower than that of the frequency modulated signal, thus improving resolution of the color signal component.

Abstract: Color video still picture playback apparatus enhances the quality of a color still picture reproduced from a video record medium. The reproduced signal is formatted as one field of video containing a succession of lines with first and second color difference signals provided in alternating line sequence. The reproduced picture, after processing, is formatted as alternating first and second fields, each having a plurality of lines such that the lines of the second field are interpolated between successive lines of the first field, and the color difference signals are provided as continuous signals, with interpolated signals being provided in alternate lines. To achieve this, first and second switches operated at the field rate are associated with first and second delay lines of one-half-line and one line delay times, respectively, and an adder circuit connects the outputs of the delay lines to one input of the second switch.
