Abstract: A vehicular machine available for transplanting vegetal seedlings onto seedbed lines comprising; a planting unit which is furnished with a plurality of vegetal seedling mounting tables and planting levers for transplanting vegetal seedlings onto seedbed lines supplied from these mounting tables disposed on the back side of a working truck hauled by a tractive vehicle; and a working step which facilitates an operator to mount himself on the working truck in order to replenish vegetal seedlings to respective mounting tables of the planting unit. The working truck itself is held by a plurality of supporting wheels which are respectively aligned with the level line identical to that of those wheels of the tractive vehicle.

Abstract: An input signal specified by an input frequency is divided by an out-of-phase type input hybrid coupler, into two divided signals with regard to the power of the input signal, where the divided signals have different phases. The input frequency of each of the divided signals is multiplied by a frequency multiplier connected with the input hybrid coupler, producing frequency multiplied signals each specified by the multiplied frequency. The frequency multiplied signals are composed by an out-of-phase type output hybrid coupler with regard to power, producing an output signal specified by the multiplied frequency. A phase shifter is provided between the input and the output hybrid coupler for varying the phase difference between the frequency multiplied signals, so that the frequency multiplied signals are composed in in-phase.

Abstract: A structure for fixing an optical cable holding box to a printed circuit board whereby the fixed position of the optical cable holding box can be changed at will and occurrence of warping in the printed circuit board can be effectively prevented. A pair of extended first metal plates having a plurality of screw holes formed therein at equal spaces are fixed to the printed circuit board in the vicinity of its upper and lower edge portions along the upper and lower edges. A pair of vertically extended second metal plates having a plurality of screw holes formed therein at equal spaces are securely fixed to the pair of first metal plates with screws such that they are stretched between the first metal plates and spaced apart a predetermined distance from each other. Thereupon, the optical cable holding box is securely fixed with screws to the pair of second metal plates in a desired position.

Abstract: A Land transportation system has an unmanned mobile box which rides in a tube from one place to another. Guides are affixed to the center of the tube to cooperate with guide rollers on the box to stabilize the running of the box. Wings are provided on the side of the mobile box to provide a buoyancy effect while the box is running, thereby reducing the friction between the box and tube. Additional rollers are placed on the bottom of the box, and come into contact with the bottom surface of the tube when the box is running at slow speeds. The mobile box is driven by linear motor, with the controller for the motor being located outside the tube, and the primary and secondary coils of the motor being located in the tube and on the box. The mobile box also has a signal generator which transmits a prememorized identification signal to a receiver outside the box, to identify destination and other information about the mobile box as it traverses the tube.

Abstract: A building structure comprises three sections; a first section having a living area on each floor; a second section having an elevator; a third section having a path connecting the living area and the elevator entrance. The third section has a closable ventilation opening for exhausting smoke when the fire breaks out and closing device for closing the opening means at a normal time.

Abstract: An apparatus for transplanting seedlings from a nursery pan to vegetable beds or flower beds as the case may be. The apparatus automatically takes up seedlings from the nursery pan individually pot by pot, and prior to implanting them, levelling a soil around the bed, digging holes in the bed to implant the seedlings therein, and compacting the soil around the root portions of the implanted seedlings.
