Title: Planet surface observing device
Inventor: ONAKA SUEO
IPC: B64G1/66
Filed: 1993-03-31
Abstract: PURPOSE:To improve an scanning efficiency of a planet surface observing device mounted on a spinning satellite remained stationary in the sky above the equator of the planet or circling on the track around the planet to scan the surface of the planet by utilizing the spinning of the satellite. CONSTITUTION:While a satellite 2 spins, a light guide means 4 mounted on the satellite 2 is rotated in the opposite direction to the spinning direction of the satellite 2. Thus, the light guide means 4 will scan in the spinning direction with the rotational speed corresponding to a difference between the spinning speed of the satellite 2 and its own relative rotational speed. By setting the differential rotational speed lower than the spinning speed, a time taken for scanning a field of view gets long to improve a scanning efficiency, so that the picture image of the planet surface can be taken sharply.

Title: Ink jet head
Inventor: USUI MINORU
IPC: B41J2/055
Filed: 1990-03-22
Abstract: PURPOSE:To make it possible to print colors in full at a low cost by using piezoelectric material having electrodes on the surface thereof as a pressure generating member, providing piezoelectric charging means constituted of means for exciting the piezoelec tric material at a natural period of a thickness oscillation thereof and means for controlling the excitation frequency of the thickness oscillation of the piezoelectric material. CONSTITUTION:A piezoelectric material 30 is layered on a base board 10, a common electrode 32 is arranged therebetween, and drive electrodes 31 are arranged crosswise. Nozzles 21 formed on a nozzle plate 20 are arranged on the piezoelectric material 30 so as to face activating areas 33. The space between the nozzle plate 20 and the piezoelectric material 30 is several tens mum being filled with an ink 40. When a voltage is charged to the active part 33 at the same period as the natural period of the active part 33 of the piezoelectric material 30 by only a half time thereof, the active part 33 makes a displacement. The natural period of the active part 33 becomes longer than that of other parts of the piezoelectric body by a rate that the electrodes are attached to both sides. As a result, the oscillation of the active part 33 is sealed only at the place of the active place 33 and only this part can selectively be oscillated, so that the quantity of an ink drip 41 can be controlled.

Abstract: PURPOSE:To reduce the discrimination operation of a slave equipment by releasing a data link in accordance with the discrimination of dissidence between an address signal obtained after sending a burst signal from a master equipment to the slave equipment and the address signal of the slave equipment itself. CONSTITUTION:When an address signal or a control signal is sent from the master equipment 1 to slave equipments 2, all slave equipments 2 discriminates whether the address signal obtained after sending a burst signal coincides with the address signal of itself or not, and a slave equipment 2 which is decided to be dissident releases its data link with the master equipment 1 by a CPU M2 and a data link switching part G2. Since all the slave equipments receiving no transmission request from the master equipment 1 interrupt communication with the master equipment 1 until detecting a burst signal again from the laster equipment 1, the slave equipments receiving no communication request are released from the discrimination processing of signals successively sent from the master equipment 1.

Title: Traveling device
Inventor: YAMAMURA NORIO
IPC: B62D55/075
Filed: 1996-03-28
Abstract: PROBLEM TO BE SOLVED: To change the direction of a traveling device safely even during moving up and down the stairs by involving a controlling means which controls a driving device so that it may restrain a difference in rotational speed given to the right and left crawlers based on a detected siginal from an inclination angle detector when counter/counter-clockwise turning indication of the traveling device is inputted into an inputting device. SOLUTION: When a device is located halfway on the stairs, an inclination angle detector 3 which is incorporated in the device detects the angle of the stairs and outputs it to a controller 4. The controller 4 compares the angle with a preset angle, and when the detected angle is larger, it determines that the device is located on the stairs automatically, and furthermore, a command value is multiplied by a deceleration coefficient (which is set to 1 on a flat and to 1 or less on the stairs). For example, if the deceleration coefficient is 0.5 and the device is turned halfway on the stairs, the rotational speed of the left crawler is decreased to a half and that of the right crawler is decelerated to 1/4. A difference in the rotational speed between the right and left crawlers is thus decreased, and the speed of the traveling device is decelerated.

Title: Variable magnification optical device
Inventor: KITAJIMA TADAYUKI
IPC: G02B15/00
Filed: 1979-06-11
Abstract: PURPOSE: To achieve the compactification and cost reduction of the device by suitably changing the focal length of an in-mirror lens along with the dislacement of the in-mirror lens holding base having the optical axis direction of the in-mirror lens as its moving components at the time of changing copying mangification.  
     CONSTITUTION: The optical drive wire 20 from one end 21 of a base 19 is inverted by a movable pulley 16, is wound by required number of turns on a drive pulley 17, and goes toward the driven pulley 18 on the opposite side. At the ordinary copying, the reversible revolutions of the drive pulley 17 cause the 1st mirror 11 and the 2nd mirror 12 to perform scanning parallel to an original platen 10 at the speed ratio of 2:1. At the varied magnfication, for example, at the scale-down, the table 19 displaces by the specified amount in the arrow A direction, causing the 2nd mirror 12 to displace in the same direction by half as much as that of the in-mirror lens 14. Also, the focal length of the lens 14 is suitably changed by the drive system. After this, the speed of the 1st reflecting mirror 11 and the 2nd reflecting mirror 12 becomes the speed inverse times the copying magnification as compared to that at the equal magnification, thus the scanning is done at a speed of 2:1. In this way, the compactification and cost reduction of the device are made possible.

Abstract: PURPOSE: To prevent fuel in the mixed air from condensation by providing the air inlet chamber on the wall side of the crankcase, in a crank chamber precompression type two-stroke engine.  
     CONSTITUTION: An opening port 1b to communicate the inside and outside is formed on the wall side of a crankcase at the lower part of an air inlet path 11, and a cover 15 which is expanded outward is fixed to be able to be mounted and dismounted by bolts and other means on the outside.

Though when a piston 3 comes into the descending stroke, the moving wall 16 is as shown by broken lines at two points, since counterflow is checked by means of a check valve 12, and at the same time as scavenging ports 7a, 7b are opened, the mixed air is induced into a combustion chamber 5. Since heat is received through the crankcase 1 into the air inlet chamber 17, fuel in the mixed air is not involved in condensation.
