Title: Backlash control system
Inventor: SAKAMOTO KEIJI
IPC: G05D3/12
Filed: 1987-06-24
Abstract: PURPOSE: To stably control a mechanical system even in a backlash area, by detecting the backlash area from a difference between the position of a motor and that of a machine, and adding a correction loop in a servo motor control system.  
     CONSTITUTION: The output of a velocity loop 4 consisting of a servo amplifier and a servo motor shows motor velocity Mv, and the output of an integrated item 5 goes to the position Mp of the motor, and backlash 6 is generated when the rotational direction of the motor changes, and the position MTp of the machine is fed back to a computing element 1. A computing element 7 detects the backlash area from the difference between the position Mp of the motor and the position MTp of the machine, and multiplies it by a proportional gain Ka, and negative-feeds it back to a computing element 3 as a correction signal Cs, and the excessive output torque of the servo motor in the backlash area can be prevented from being generated. In such a way, since a system is constituted so that the correction loop can be added in the backlash area, it is possible to control the mechanical system stably even in the backlash area.

Title: Contents transmitter and contents receiver
Inventor: OKAMURA SHINSAKU
IPC: H04N5/445
Filed: 1999-06-04
Abstract: PROBLEM TO BE SOLVED: To conveniently select and retrieve desired contents. SOLUTION: A transmitter 1 generates a key frame respectively based on a 'basic attribute' and a 'keyword' relating to the attribute and contents of various contents 5. Then the transmitter 1 gives each generated key frame to each of the contents 5 and transmits the resulting contents. A receiver 3 receives each of the contents 5', separates each key frame from them and references a 'viewer attribute' and a 'retrieval keyword' relating to each key frame and a stored viewer. Then the receiver selects contents to be displayed based on them. In the case of selecting a plurality of contents, the 'viewer attribute' is extracted by using a logical expression (e.g. AND, OR, EXOR) or the like and the contents are narrowed based on them.

Title: Automatic controlling device of waterway lining machine
Inventor: SHIMIZU MIYUKI
IPC: E02B5/02
Filed: 1979-12-05
Abstract: PURPOSE: To equalize the concrete thickness of the right and left slope of a curvilinear waterway by a method wherein a deflection due to a tyre difference is detected by fitting a steering sensor in a lining machine and a cylinder for adjusting the caterpillar width of a waterway lining machine is expanded.  
     CONSTITUTION: When a trimming groove 5 is curved, the center of a car body 20 deflects from the center of the groove 5 to the right hand because of the tyre difference of catapillars 21, 22 of a waterway lining machine 2. In accordance therewith, the center of a lining machine 6 also deflects from the center of the groove 5 to the right hand. In accordance with this deflection, a steering sensor 81 emits a signal. This signal is sent to a catapillar control system, and when the signal is discriminated as a value more than a given value, cylinders 23, 24 are expanded by a same stroke simultaneously. Accordingly, the grounding position and the catapillar width of the catapillars 21, 22 do not vary but only the car body 20 is moved to the left direction, therefore, the lining machine 6 is also moved to the left direction. In this way, the center of the car body 20 and the lining machine 6 is made to coincide with the center of the groove 5, as a result, the concrete thickness of both slopes 50, 51 can be made equal.

Abstract: PURPOSE:To produce the high molecular piezo-electric conductor provided with highly efficient thickness piezo-electric property. CONSTITUTION:The thickness piezo-electric property of the copolymer P (VDF- TrEE) composed of vinylindene fluoride (VDE) and trifluoroethylene (TrFE) is based on the findings that said property is under the remarkable influence of the composition ratio of VDF and TrFE as well as the production processes, heat treatment before pauling and the resultant minute composition (morphology) of the solid while the essence of said property is characterized by pauling the molding after the heat treatment of P (VDF-TrFE) formed by means of coating solution or casting at the approximate temperature between the crystalline phase transition point Tm' and the melting point (Tm) or pauling said molding P at the approximate temperature between Tm' and Tm. In this case, the Tm' is represented by the peak temperature absorbing heat at the rising temperature DSC curve of said molding normally several to scores derees lower than Tm. It is unknown yet to which phase transition the Tm' corresponds but it is evident that the phase transition is the high dielectric-constant dielectric phase transitions caused by turning around the molecular axis in parallel with the molecular chains.
