Title: Duplex optical communication method and communication equipment
Inventor: SATO AKIO
IPC: H04B10/00
Filed: 1993-02-25
Abstract: PURPOSE:To make the optical communications equipment small in size, light in weight and low in cost by using an infrared ray of the same wavelength so as to process vehicle sensing and data transmission reception by a single MPU. CONSTITUTION:In order to sense a vehicle, an optical sensor S on ground R emits an infrared ray of a predetermined wavelength to the ground R on which a vehicle V is in existence for a predetermined time for a predetermined period from a light emitting section and receives the ray. A processing section monitors a waveform of a received wave and when there is any waveform indicating the presence of the vehicle V, the processing section sends a signal to the vehicle V for a time set through time division during a predetermined period and receives the signal for a time through time division separately. On the other hand, when the vehicle receives the signal from the sensor S, the vehicle continues the reception for a set time through time division for a predetermined period and sends a signal from the vehicle for another setting time through time division.

Title: Vacuum cleaner
Inventor: ONDA MASAKAZU
IPC: A47L9/00
Filed: 1992-02-24
Abstract: PURPOSE:To reduce damage and noises by improving a running performance during the movement to absorb impact as caused by a floor surface, threshold and the like in a vacuum cleaner with a roller for moving. CONSTITUTION:A cylindrical bearing 10 is fixed being inclined outwards on the rear side of both sides of the main body 1 and a shaft 11 is inserted into a bearing 10 free to rotate to prevent slipping thereof with a pawl. A circular roller 13 is fixed on the shaft 11 through a side plate 12 and the side plate 12 is made up of an elastic member. For example, a thin synthetic resin material of polypropylene is used. When a user moves the main body 1, the weight of a vacuum cleaner works mainly on the roller 13 as the cleaner runs over a step of a floor surface. a threshold or the like. Thus, the cleaner deforms outwards (in the direction of the arrow) because of elasticity of the side plate 12 to absorb impacts.

Abstract: PURPOSE:To improve productivity and attain improvement of the life of cutting blades by sandwiching confronted joint billets with a pair of rotating drums from the upper and lower sides, and cutting out protruded parts by meas of cutting blades provided around the rotating drums. CONSTITUTION:A preceding billet S1 and a succeeding billet S2 are confronted and joined to each other by a joint device A. Arrival of a protruded object S3 generated by the confronted joint is detected with a position detecting device 3.

Abstract: PURPOSE:To grind a work uniformly without generating secondary burrs, by chamfer-grinding with grinding belts angular portions of a work, which is transferred on guide elements by a transfer means, while rotating the work by grinding pressures from the grinding belts. CONSTITUTION:A work 11 transferred on a guide element 12 by a transfer means comes into contact with a grinding belt 18 as it is moved. The work 11 is downwardly urged by the rotational force of the belt 18 to be rotated in the direction of an arrow. Since the direction in which the work 11 is rotated by the belt 18 is opposite to the direction in which the work 11 is urged by the transfer means 13, the work 11 is rotated as it keeps contacting a claw 15. Accordingly, an edge portion of the work 11 is chamfered uniformly in a short time by the gringing belt 18. In order to chamfer edge portions at both sides of the work 11, a guide element 24 and a grinding body 25 are arranged such that they face opposite sides with respect to the guide element 12 and the belt 18, respectively. In this structure, the work 11 transferred along the guide element 12 and chamfered at an edge portion thereof on one side is then chamfered at an edge portion thereof on the other side on the guide element 24.
