Abstract: PURPOSE:To satisfy both a good operation stability and a riding comfortableness by composing the lateral link of a trapezoid lower arm separately from the trailing arm of the lower arm, and combining the outer end of the lateral link to the trailing arm to allow to fluctuate freely in the longitudinal direction. CONSTITUTION:The lateral link 12 of a trapezoid lower arm 1 is composed separately from the trailing arm 11 of the lower arm 1, the lateral link is combined to the trailing arm 11 through a ball joint or a bush 11a, and the lateral link 12 is made possible to fluctuate in the longitudinal direction to the trailing arm 11. And the included angle alpha of the fluctuating axis X-X of the trapezoid lower arm 1 and the lateral link 12 is made in an acute angle. As a result, by making a bush 12a hard and the bush 11a of the trailing arm 11 soft, the lateral rigidity is increased to improve the operation stability, and the longitudinal rigidity is reduced to improve the riding comfortableness. And since the angle alpha is made in an acute angle, the steering-in condition is made in a braking so as to improve the stability in the turning braking operation.

IPC: H04L27/20
Filed: 1989-04-28
Abstract: PURPOSE:To make the band of a transmission spectrum narrow by subtracting a distortion wave component from an output signal of a class AB power amplifier and sending the resulting signal. CONSTITUTION:An output signal of a class AB power amplifier 8 is attenuated by an attenuator 9 and an output signal of low pass filters 3, 4 is subtracted from a signal resulting from applying phase modulation to the attenuated output signal with a synchronization detector 10 to obtain a component subject to synchronization detection from the distorted wave component of the class AB power amplifier 8. The component is subject to phase modulation again by an orthogonal modulator 13 and the result is amplified by a class AB power amplifier 14, then the output signal of the class AB power amplifier 14 is equal to the distortion wave component of the class AB power amplifier 8. When the output signal of the class AB power amplifier 14 is subtracted from the output signal of the class AB power amplifier 8, the distorted wave component of the class AB power amplifier 8 is eliminated. Thus, the band of the transmission spectrum is made narrow.

Abstract: PROBLEM TO BE SOLVED: To facilitate an assembly work for concrete forms and to facilitate a disassembly work. SOLUTION: A corner material 76 for an interior angle is arranged at a corner part where form plates 52 and 54 are orthogonally facing each other. A clip 70 is forcibly fitted in bars 56 and 58 of form plates 52 and 54 and the corner material 76 for an interior angle is coupled to the form plates 52 and 54. Outer form plates 2 and 4 are then coupled to the inside form plates 52 and 54.

A corner material 60 for an exterior angle is coupled to the outer form plates 2 and 4 with a clip 70 forcibly fitted in bars 6 and 7. This way completes assembly of the form plates.  When the forms are disassembled, coupling between the corner materials 76 and 60 and the bars 56, 58, 6, and 7 is uncoupled by strongly stretching a curved part 70b of the clip 70.

IPC: H03B19/14
Filed: 1984-05-30
Abstract: PURPOSE:To increase a frequency range which satisfies the oscillation conditions by connecting a source electrode of the 2nd dual gate FET to the 1st gate of the 1st dual gate FET to form a resistance feedback circuit and adding terminals through which the signals to be frequency divided with different phases are supplied. CONSTITUTION:A reverse-phase signal emerges at a drain electrode 12 in case a forward-phase signal emerges at the 1st gate electrode 14 of the 1st dual gate FET11. At the same time, a reverse-phase signal is also produced at a source electrode 22 of the 2nd dual a gate FET21 and then fed back to the electrode 14. Then a feedback circuit has oscillations as long as the gain of this circuit is larger than 1. The oscillation is possible up to about 6GHz with use ofa GaAs dual gate FET having its gate length set at about 1.0-0.5mum. Thus the oscillation is possible up to a range between a low frequency and 6GHz or so with use of the GaAs dual gate FET. Therefore the division is possible with this feedback circuit over an octave f=6GHz-12GHz when the mixing is carried out by means of gate terminals 16 and 25.
