Title: Distortion compensation circuit
Inventor: HASEGAWA JUNICHI
IPC: H03F1/32
Filed: 1988-06-13
Abstract: PURPOSE:To send an input signal not requiring compensation of distortion as the input signal without any modification by discriminating whether or not the input signal requires distortion compensation depending on number of carriers of the multi-carrier input signal and connecting/disconnecting an output of a distortion generator based on the result of discrimination. CONSTITUTION:The multi-carrier signal is inputted to a carrier number discrimination circuit 7 so as to discriminate whether or not the carrier number of the carrier input signal requires distortion compensation. As a result of the discrimination, when it is discriminated that no distortion compensation is required for the multi-carrier input signal, a switch circuit 8 interrupts the output of the distortion generator 2, and if the necessity of distortion compensation is discriminated on the other hand, the output of the distortion generator 2 is sent to a phase shifter 3 and a variable attenuator 4. Thus, undesired distortion compensation is avoided for the multi-carrier input signal with less carrier number.

Title: Magnetic recorder
Inventor: YAMANAKA TAKESHI
IPC: G11B15/66
Filed: 1978-11-25
Abstract: PURPOSE: To realize a miniature recorder by making a tape run at a desired speed by the small-diameter part of a capstan in recording and playback modes and by its large-diameter part in rewind mode.  
     CONSTITUTION: A VTR main body has a two-stage cassette insertion part. With a video tape cassette inserted into guide member 22 at the lower stage, the cylinder of VTR intrudes into the cassette and while a magnetic tape is automatically wound around its outer circumference, the small-diameter part of capstan 44 is pressed against pinch roller 11 to rotate at a low speed, a recording or playback speed, with the tape sandwiched. With the cassette inserted into the upper-state insertion part, the large-diameter part of capstan 44 comes in contact with pinch roller 11 and is reversed to rewind the tape at a high speed. At this rewind position, the cylinder never intrudes into the cassette and the tape does not touch the cylinder. As a resutl, fractional resistance is low, and consequently a small-output driving motor can be used, so that the VTR main body can be miniaturized.

Abstract: PROBLEM TO BE SOLVED: To keep a delay effect of freeze longer by arranging crushed stones having a large water absorption so as to be exposed on a pavement face. SOLUTION: Precoated water absorptive crushed stones are scattered and pressed in a rolled asphalt paving method to expose the water absorptive crushed stones on a pavement face, or an asphalt mixture including a large quantity of water absorptive crushed stones is used. The asphalt covering the water absorptive crushed stones is worn out before long due to deterioration caused by weather, rubbing-off by car tires, frictional wear, etc. Hence, the water absorptive crushed stones having a water absorptive function are exposed on the road face.
