Abstract: A floor panel including a protrusion portion which extends in a transverse direction of a vehicle and crosses a floor tunnel. The protrusion portion ensures a rigidity of the floor panel in the transverse direction of the vehicle. Therefore, it is possible to make a floor panel thinner while maintaining its rigidity. In particular, when a cross portion of a floor tunnel and a protrusion portion is protruded more than any other portion of the floor panel, the rigidity of the floor panel is increased. Further, when the protrusion portion is provided under a front seat and a slope face connects the top of the protrusion portion to floor face, a space under the rear side of the protrusion portion is available for disposing a fuel tank. Therefore, space efficiency is improved. Further, the slope face is available for a rear-seat footrest.

Abstract: A first rotational head of a first azimuth angle and a second rotational head of a second azimuth angle are arranged on a rotational drum rotated at a constant rotational speed. Also, input digital signals are processed in a signal recording system to form blocks of digital recording signals, a magnetic tape is moved by a tape driving unit according to an information signal generated in a control unit, and the blocks of digital recording signals and the information signal are recorded on the magnetic tape in a recording operation through the first and second heads alternately tracing the magnetic tape. In a reproducing operation, the signals are read through the first and second heads and are reproduced in a signal reproducing system. When the input digital signals are transmitted at a standard data rate, the magnetic tape is rotated at a first traveling speed in the recording and reproducing operations.

Abstract: A resin coated metal pipe has a plane surface portion formed with a coating resin as one body. By arranging many resin coated metal pipes in parallel such that the plane surface portions point upward, a lightweight structure, such as a bench, a flower stand, a draining board, and so forth can be assembled easily. Slippery or anti-slippery synthetic resin may be used as a part of or all the plane surface portion having a color different from the coating resin.

Abstract: A noise reduction circuit for a video signal, comprises a feedback type comb filter in which an output video signal of a delay circuit which delays a video signal by one or two horizontal scanning periods, is fed back to an input side of the delay circuit through a feedback path, and an equalizer circuit coupled in series with the feedback type comb filter. The feedback path comprises a highpass or bandpass filter circuit and a coefficient multiplier which are coupled in series. The equalizer circuit has a frequency characteristic complementary to an envelope characteristic in a frequency characteristic of the feedback type comb filter.

Abstract: A color video signal dubbing system comprises a reproducing apparatus and a recording apparatus. The recorded signal is a multiplexed signal of a frequency-modulated luminance signal obtained as the result that a luminance signal separated from the color video signal frequency-modulates a carrier wave to occupy a predetermined frequency band and a frequency-converted carrier chrominance signal obtained by frequency-converting a carrier chrominance signal having a color burst signal which is separated from the color video signal to a band lower than that of the predetermined frequency band.

Abstract: A system for controlling rotational direction switchover and for variably controlling the rotational speed of a motor comprises a circuit for switching over the rotational direction of the motor, a circuit for supplying rotation driving voltage to the motor thereby to drive it at a speed depending on the rotation driving voltage, a single voltage varying unit for varying voltage continuously, and a control signal generation circuit which receives variable voltage from the voltage varying means to generate a rotational control signal for the rotation driving voltage supplying circuit and further to generate a rotational direction switchover control signal for the switchover circuit. The voltage of the rotation control signal produced by the control signal generation circuit decreasing as the variable voltage approaches a predetermined value, reaching a minimum when the variable voltage coincides with the predetermined voltage, and increasing as the variable voltage goes beyond the predetermined value.

Abstract: A tape recording apparatus comprises a first mechanism capable of varying, between a maximum and a minimum length, a tape travel path extending between a recording and reproducing head and a tape take-up roll. A second mechanism controls the first mechanism so that the length of the tape travel path becomes the maximum length at the time of ordinary recording and at the time of editing. The length of the tape travel path becomes the minimum length at the time of a pause mode prior to the editing recording. A third mechanism pulls back the tape by a length equal to the difference between the maximum and minimum lengths, at the time of the pause mode, of the tape path between the tape roll on the tape supply side and the recording and reproducing head. A fourth mechanism detects when the first mechanism reaches substantially maximum tape length at the time of the editing recording mode, and causes the start of editing recording by the recording and reproducing head.

Abstract: The invention provides an apparatus for controlling the rotation of a rotating body in a recording and/or reproducing apparatus. First, the apparatus detects the rotational speed of the rotating body, as it is driven by a DC motor. Detection is in terms of a frequency which is n times the speed, in which n>> 1. Second, there is a detection of the rotational phase of the rotating body. The DC motor is driven to rotate in accordance with a controlling signal obtained by using first and second output error signals responsive to the first and second detections. The DC motor is driven by means for superimposing an AC signal generated with a constant period and the first and second output error signals. The superimposed signals are sliced at a predetermined level to perform "ON" - "OFF" operations and a smooth output to control the driving rotation of the DC motor.
