Title: Steering controller for unmanned traveling vehicle
Inventor: SASAKI TAKASHI
IPC: G05D1/02
Filed: 1992-05-21
Abstract: PURPOSE:To reduce the meander or vibration of a vehicle by performing change gear control for steering velocity in a direction to return the vehicle based on the magnitude of getting the unmanned traveling vehicle out of a guiding line. CONSTITUTION:Concerning the unmanned traveling vehicle to enable unmanned traveling by automatically controlling the steering while detecting the guiding line embedded in the ground with guide sensors 5L and 5R, the absolute value of the composed voltage of the left and right guide sensors 5L and 5R arranged on the left and right sides of a sensor frame 1 for detecting the guiding line is calculated and corresponding to the level of this absolute value, the steering velocity is changed. Namely, when the machine body is considerably gets out of the guiding line, the composed voltage absolute value of the left and right guide sensors 5L and 5R is increased. Since it is necessary to speedily return the machine body to the position of the guiding line in this case, the steering velocity is accelerated. Reversely when the machine body is slightly shifted on the right and left sides of the guide line, the steering velocity for return is decelerated. Thus, the state of repeating the meander for a long time or traveling the vehicle while vibrating it at all times because of the convergence difficulty of control can be eliminated.

IPC: H04B1/06
Filed: 1997-05-20
Abstract: PROBLEM TO BE SOLVED: To improve the operating convenience by setting a reception frequency of a reception circuit according to frequency data of a data table when a prescribed key operation is made to select a broadcast station broadcasting a teletext multiplex broadcast program thereby allowing the receiver to quickly select the teletext multiplex broadcast station. SOLUTION: In the step 102, a frequency division ratio N corresponding to a frequency that is higher than and closest to a frequency received at present among frequencies stored in a data table is selected and set to a variable frequency divider circuit. Thus, the frequency division ratio N of the variable frequency divider circuit is updated, and from the point of time of this revision, then a broadcast program with the frequency selected from the table is received. Then in the step 111, a level of a level detection signal S33 is checked. When the broadcast wave signal with the selected frequency cannot be received according to the level check, a succeeding frequency division ratio N on the data table is read in the step 112.  The processing above is repeated and whether or not a broadcast program with the frequency resulting from the selected frequency division ratio N can be received is sequentially checked.

When the quantity of used water decreases in the nighttime, etc., the swing angle of swing plate 18 provided to sending-out side 2 of control valve 1 decreases and communicating tube 13 is cut off by alternation valve K. As a result, only low-pressure pilot valve P 2  operates to hold sending pressure low. When the quantity of used water increases, plate 18 swings, communicating tube 13 is opened and high-pressure pilot valve P 1  operates to increase the sending pressure.

Title: Manufacture of cupronickel clad uoe steel pipe
Inventor: HIRANO OSAMU
IPC: B23K9/00
Filed: 1990-05-22
Abstract: PURPOSE:To manufacture the cupronickel clad steel plate excellent in quality such as seawater resistance with high efficiency by combining plasma keyhole welding and TIG welding of high quality in the manufacturing state of the UOE steel pipe of high quality with high efficiency. CONSTITUTION:At the time of edge penetration, cutback edge penetration 1 of cladding material is first carried out in consideration of cladding by welding carried out later on. Since tacking is carried out by TIG welding, variation of thickness at the time of welding of a root part carried out by plasma keyhole welding later on is suppressed and a plasma arc is stabilized. In addition, since the root part is subjected to plasma keyhole welding, the root part is completely molten and a narrow and deep nugget shape is obtained. As a result, at the time of cutback edge penetration, its groove can be narrowed and the rate of dilution at the time of TIG cladding by welding can be reduced. Accordingly, the clad steel pipe excellent in seawater resistance almost similar to clad material around a weld zone is obtained.
