Title: Polarized wave converter
Inventor: ABE HISASHI
IPC: H01Q15/24
Filed: 1984-02-08
Abstract: PURPOSE:To convert a vertically polarized wave (or horizontally polarized wave) into a horizontally polarized wave (or vertically polarized wave) without changing the progressing direction of a radio wave by installing oppositely a converter converting a linearly polarized wave into a circularly polarized wave and a converter converting a circularly polarized wave into a linearly polarized wave. CONSTITUTION:In using a meander line as a circularly polarized wave generator 4 and as a converter 5 converting a circularly polarized wave into a linearly polarized wave, the direction of inclination of the meander lines is arranged in the same direction. When a polarized wave EV (vertically polarized wave) is made incident with an angle of 45 deg. in the direction of the meandering line, the polarized wave EV is decomposed into polarized waves EC and EL having a slope of 45 deg. to the EV and orthogonal to each other. In selecting properly the line constant of the meander line, since the polarized wave EL has a phase lead by 90 deg. to the polarized wave EC after the transmission of the meander line, the polarized wave EV transmitting through the circularly polarized wave generator 4 is converted into a right-handed rotatary circularly polarized wave. After the right-handed rotatary circularly polarized wave incident on the converter 5 after the transmission of the converter through the simple principles is converted into a polarized wave EH (horizontally polarized wave) and the vertically polarized wave is converted into the horizontally polarized wave without changing the progressing direction of the radio wave.

Title: Ultrasonic wave probe
Inventor: SAITO TAKAYOSHI
IPC: G01S7/521
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To extend the directive angle of an ultrasonic wave in an arrangement direction of piezoelectric elements in the ultrasonic wave probe in which the plural piezoelectric elements are arranged. SOLUTION: Acoustic matching layers 4, 5 are provided to front face of plural piezoelectric elements, arranged in straight lines to configure the ultrasonic wave probe. The respective acoustic matching layers 4, 5 are divided into plural parts. The respective ultrasonic wave sources is decreased by dividing the acoustic matching layers and an ultrasonic wave close to a spherical wave or a cylindrical wave is emitted, then the difference between the forward intensity and the intensity in an oblique direction is decreased. Thus, directivity is made flat and the plural piezoelectric elements are driven by changing the phase. When electrically converging or deflecting an ultrasonic wave, the ultrasonic wave is emitted over a wide angle. Furthermore, since the ultrasonic wave beam can be made to converge thinly, the resolution is improved.  Even in the case of receiving an ultrasonic wave, since the reflected ultrasonic wave in an oblique direction is received efficiently, the sensitivity in the oblique direction is enhanced to widen the directivity characteristic.

Title: Driving release mechanism of paper feeder
Inventor: KUSAFUKA YOSHITO
IPC: B41J13/00
Filed: 1988-02-01
Abstract: PURPOSE:To make it easy to change the operation of a printing shifting for use with a continuous paper and for use with cutform papers, by so arranging that when a command for changing the type of papers to be fed is issued to a printer, a release lever and a lock lever are driven to release or couple the engagement of gears. CONSTITUTION:In the case of using a continuous paper 2, a command is so issued that a release lever 26 is pulled down to separate a feed roller 10 from a platen 3, which is transmitted to a tractor 4 within a main body of a printer. A lock lever pushing part 28 of a lock lever 27 is abutted against the tip end of the lever 26. As a result, the driving force of a platen gear 37 is not transmitted to a paper feed gear 38. Therefore, the paper feeding operation by the paper feeder is not carried out, without feeding a cutform paper in the printer. On the other hand, when the cutform paper 1 is used, the lever 26 is pulled down so that the roller 10 is pressed in contact with the platen 3, and the tip end of the lever 26 is separated from the lever 27, and accordingly the driving force of the platen gear 37 is transmitted to a gear 29. Thus, the paper feeder is easily switched for feeding the cutform of papers with ease.

Filed: 1984-02-08
Abstract: PURPOSE:To make a run along a sharp curve excellently by decresing the responsiveness of the steering operation of a steering wheel to small oscillations of sensos in a straight run, and increasing it to large turns of the sensors at a curved course. CONSTITUTION:A frame 13 for steering supports the steering wheel 14 pivotally in the automatic steering device for an unmanned vehicle. A couple of sensors 17a and 17b detect a right or left position shift from a guide line and drives a motor 19 on the basis of the detection result to control the steering wheel 14 automatically. The ratio transmitting mechanism 21 consisting of noncircular gears 22a and 22b is interposed in the driving system for the steering wheel 14, so while the steering angle from the straight run is small, the steering wheel 14 rotates in a speed reduction state to the rotations of the couple of sensors 17a and 17b and the speed reduction ratio decreases gradually as the steering angle increases. When the angle increases, the steering rotation is carried out in a speed increase state.
