Title: Antenna unit
Inventor: GOMI SHINTAROU
IPC: H01Q3/24
Filed: 1979-08-15
Abstract: PURPOSE:To improve remarkably the performance of excluding disturbance due to a multipath phenomenon by using outputs of two loop antenna elements by switching. CONSTITUTION:A received radio wave arrives in the direction where antenna element 3b nearly has maximum sensitivity. As the incident direction of the radio wave changes from arrow X to arrow Y, the sensitivity of element 3b decreases accordingly, reducing its output voltage. As the incident direction of the radio wave becomes closer and closer to the tangential direction of the directivity curve shown by the solid line, the input level of the receiver lowers suddently. When the input level decreases below a fixed threshold value, the switch method is put into operation to change the antenna element to be used over to 3a.

Title: Photo repeater feeding system
Inventor: MOTEGI MITSUHIRO
IPC: H04B10/80
Filed: 1978-08-26
Abstract: PURPOSE:To feed power without causing no induction by supplying the power of a photo repeater by photo energy by making use of optical fiber for photo-signal transmission. CONSTITUTION:From feeding light sources PLI and PL2 of light wavelength (lambda2) different from light wavelength (lambda1) of a photo signal light source, photo energy is supplied to photo repeaters REP1 and REP2 via optical fibers F1 and F4 for photo- signal transmission. In the photo repeaters, branching filters D1 and D2 separate photo energy, from feeding light sources PL1 and PL2, from the photo signals and then supply it to photoelectric converters LE1 and LE2, whose electric conversion output is used as feeding power. Consequently, the terminal station and repeaters are connected by only optical fibers, which results in non-induction constitution.

As frequency, it is tens of KHz, for example. If so, in the detector 7 at the light receiving side, there is seen such a phenomenon as reducing the width of an optical pulse detected according to force given to the optical fiber 5.  Utilizing this phenomenon, such a fact that the optical pulse width passed through the fiber 5 is periodically altered in response to the discharge frequency of a Karman vortex is detected, from which the vortex discharge frequency is taken out by means of signal processing.

Title: Wheel
Inventor: URANO KOUSAKU
IPC: B60B19/00
Filed: 1979-08-20
Abstract: PURPOSE: To enhance accuracy and durability of a wheel, by making the peripheral side of wheel of a vacuum cleaner or the like, of a thin and a thick elastic walls.  
     CONSTITUTION: When the suction head of a vacuum cleaner is reciprocated on a floor, a wheel 13 is rotated as its thin wall 16 is deformed inwards depending on load. Since the thin wall 16 is soft and elastic, it is deformed in accordance with the recesses and profections of the floor 20 to absorb fluctuation due to the recesses and projections. When the thin wall 16 is deformed across a space 17, the wall comes into contact with a cylinder 18 so that the wall is reinforced and protected by the cylinder. The deformation of the thin wall 16 is thus restricted within its elastic limit even if overload is applied. This results in protecting the thin wall from damage or the like.
